How do i parse the KairosSDK JSON recognise response in Swift? - json

For those who don't know what the Kairos SDK is, it's basically a facial recognition api.
When you give it an image, it will tell you who if they can match you with someone in the database.
When i give it an image; the api sends me back this response:
[images: (
{
attributes = {
gender = {
confidence = "80%";
type = F;
};
};
candidates = (
{
"enrollment_timestamp" = 1436883322;
face3rd = "0.988351106643677";
},
{
"enrollment_timestamp" = 1436883214;
hi = "0.94137054681778";
},
{
"enrollment_timestamp" = 1436883132;
hi = "0.94137054681778";
}
);
time = "6.43676";
transaction = {
confidence = "0.988351106643677";
"distance_apart" = "0.046980559825897";
"gallery_name" = test1;
height = 482;
"matching_threshold" = "0.4";
"next_subject" = hi;
"next_subject_confidence" = "0.94137054681778";
"simularity_threshold" = "0.1";
status = success;
subject = face3rd;
topLeftX = 148;
topLeftY = 92;
width = 482;
};
}
)]
What i have done is put three images in the database and have called each of them respectively, face3rd, hi, hi (sorry for the two hi's)
I have been trying to parse the names and the number next to it for soo long, i can get around the 6 second response time.
The reason i have not been able to get the names is because, as you can see, i don't know what to tell Swift to look for. The image name changes depending on who i get back.
I don't know if i've explained my situation, bestly, but if you look at the response. The parts that say:
face3rd = "0.988351106643677";
hi = "0.94137054681778";
hi = "0.94137054681778";
I need the information on both sides of the equal sign.
Thank you for your help and apologise, if reading it was pedantic or you felt like their was a lot of repetion.
Thanks!

Yes, it is poorly formatted JSON that we are returning. We will fix it in an upcoming version of the API (no release date at this time..sorry).
If all you need is the closest match, you can just access the subject variable directly and ignore the candidates array.
Otherwise, you would need to parse the candidates array manually unfortunately. I'm not sure how to do that in Swift.

trying to get properties of objects inside object properties

Sometimes JavaScript is playing with me (although the deal was that I would be playing with it...) This test code below keeps resisting so I'm looking for a little help from more clever people around here.
Answering to a recent question I tried to create a readable list of all the color IDs useable in Google Advanced Calendar API.
The request is very simple : Calendar.Colors.get()
The response is an object with a couple of properties, each one being other objects with other properties.
I can go down to the second level but the last -and most useful in this case - level returns a disturbing "undefined" (see partial log below)
And that's my question...
code with comments :
function getColorList(){
var colors = Calendar.Colors.get();
//Logger.log(JSON.stringify(colors));
for(var cat in colors){
Logger.log("category "+cat+" = "+JSON.stringify(colors[cat])+'\n\n')
}
// from there I try the "event" category
var events = colors["event"];
Logger.log('object colors["event"] = '+ JSON.stringify(events))
// then I try to get every properties in this object
for(var val in events){
Logger.log("key "+val+" = "+JSON.stringify(events[val]))
}
}
Full log is viewable here (externalized to keep this reasonably short)
Looks like (key) may be indicating a read-only definition as Sandy was eluding to.
Just make your own object from colors to loop through after converting it to string:
var json = JSON.stringify(colors["event"]);
var myObj = JSON.parse(json);
for(var val in myObj){
Logger.log("key "+ val +" = "+JSON.stringify(myObj[val]))
}

Include nested entity details but don't group by then when grouping by other fields

I working with Database first C# MVC, EF6, LINQ and JSon to try and pass data to both Highcharts and Google Maps for some of my reporting.
If I could add an image I would show you the relevant portion of my model, but sadly I need more reputation to do that...
The portion of the Entity Model I'm concentrating on right now is based on a central Docket that contains a BuildingCode as part of a one-to-many relationship to a building with and address and further relationship to the buildings polygons (for mapping). Dockets are also classified by one or more DocketTypes and thus there is a many-to-many relationship between Dockets and DocketTypes, which is not directly exposed to through the EF.
As an example a Docket which represents an investigation, could be related to the theft of a mobile phone in building A located on Campus X, not only was the cellphone stolen but the assailant also assaulted the victim in order to steal the mobile phone. So there are 2 DocketTypes here 1. Theft of mobile phone and 2. assault. Note: this is fictitious and for illustration purposes only .
One of my fundamental reports requires that I count how many docketTypes affect each building and each campus in a given period. When I display this I also need to show what the DocketTypes are.
I have no end of nightmare trying to find a way to get this right, I keep running into circular reference errors and needing to use explicit conversions when trying to model the data with LINQ so that I can pass a single nested object through JSON to the client side where displaying will occur.
In the below code I am told I need an Explicit conversion:
Cannot implicitly convert type 'Campus_Investigator.ViewModels.DocketTypeViewModel' to 'System.Collections.Generic.IEnumerable<Campus_Investigator.ViewModels.DocketTypeViewModel>'. An explicit conversion exists (are you missing a cast?)
var currentDocketQuery = from d in db.Dockets
from dt in d.DocketTypes
from bp in d.BuildingDetail.BuildingPolygons
where d.OccurrenceStartDate >= datetime && d.BuildingDetail.CampusName == Campus
select new CampusBuildingDocketTypeViewModel()
{
BuildingCode = d.BuildingDetail.BuildingCode,
BuildingName = d.BuildingDetail.BuildingName,
//BuildingPolygons = d.BuildingDetail.BuildingPolygons,
DocketTypes = new DocketTypeViewModel()
{
Category = dt.Category,
SubCategory = dt.SubCategory,
ShortDescription = dt.ShortDescription
}
};
I appreciate any ideas on how I can explicitly convert this or is that a better method I can use and avoid the circular reference error?
You included some redundant part in your query (which performs some inner join). The from bp in d.BuildingDetail.BuildingPolygons is joined in but then is not shown in the result. So it totally does not make sense. There may be duplicated elements in the result due to that. The from dt in d.DocketTypes is wrong joined in, although you need it in the result but because the DocketTypes is output per d in db.Dockets, so it's just simply queried like this:
var currentDocketQuery = from d in db.Dockets
where d.OccurrenceStartDate >= datetime && d.BuildingDetail.CampusName == Campus
select new CampusBuildingDocketTypeViewModel()
{
BuildingCode = d.BuildingDetail.BuildingCode,
BuildingName = d.BuildingDetail.BuildingName,
//BuildingPolygons = d.BuildingDetail.BuildingPolygons,
DocketTypes = d.DocketTypes
};
In fact I can see the commented line //BuildingPolygons = d.BuildingDetail.BuildingPolygons, so if you want to include that, it should also work.
If the DocketTypes has different type of d.DocketTypes, then you need a simple projection like this:
var currentDocketQuery = from d in db.Dockets
where d.OccurrenceStartDate >= datetime && d.BuildingDetail.CampusName == Campus
select new CampusBuildingDocketTypeViewModel()
{
BuildingCode = d.BuildingDetail.BuildingCode,
BuildingName = d.BuildingDetail.BuildingName,
//BuildingPolygons = d.BuildingDetail.BuildingPolygons,
DocketTypes = d.DocketTypes.Select(e => new DocketTypeViewModel()
{
Category = e.Category,
SubCategory = e.SubCategory,
ShortDescription = e.ShortDescription
})
};
I managed to solve this one by using the below. The major hassle with this is the circular referencing that exists in the model. When JSON serializes these, everything falls apart so it takes a lot of transforming to make sure that I only extract what I need. In this case grouped campus and building data (below includes the polygons which where only half commented out in the above) and then the include the detail of the DocketTypes that occurred at each building.
var datetime = DateTime.Now.AddDays(-30);
var campusDocket = from d in db.Dockets
where d.OccurrenceStartDate >= datetime && d.BuildingDetail.CampusName == Campus
group d by new { d.BuildingDetail.CampusName, d.BuildingDetail.BuildingCode, d.BuildingDetail.BuildingName } into groupdata
select new CampusBuildingDocketTypeViewModel
{
BuildingCode = groupdata.Key.BuildingCode,
BuildingName = groupdata.Key.BuildingName,
CampusName = groupdata.Key.CampusName,
Count = groupdata.Count(),
BuildingPolygons = from bp in db.BuildingPolygons
where bp.BuildingCode == groupdata.Key.BuildingCode
select new BuildingPolygonViewModel
{
Accuracy = bp.Accuracy,
BuildingCode = bp.BuildingCode,
PolygonOrder = bp.PolygonOrder,
Latitude = bp.Latitude,
Longitude = bp.Longitude
},
DocketTypes = from doc in db.Dockets
from dt in doc.DocketTypes
where doc.OccurrenceStartDate >= datetime && doc.BuildingCode == groupdata.Key.BuildingCode
select new DocketTypeViewModel
{
Category = dt.Category,
SubCategory = dt.SubCategory,
ShortDescription = dt.ShortDescription
}
};
The Answer again is ViewModels. I'm finding ViewModels seem to solve a lot of problems...

sharedobjects multiple item

Is there a way to store multiple items in a shared object? I want to store the score and it's profile name at the same time in an android game.
here is my code so far.
if(playerScore > lvl1Score.data.score1 || lvl1Score.data.score1 == 0)
{
lvl1Score.data.score5 = lvl1Score.data.score4;
lvl1Score.data.score4 = lvl1Score.data.score3;
lvl1Score.data.score3 = lvl1Score.data.score2;
lvl1Score.data.score2 = lvl1Score.data.score1;
lvl1Score.data.score1 = playerScore;
lvl1Score.data.scoreName1 = curUser;
lvl1Score.flush();
}
scoreBoard.one.text = String(lvl1Score.data.score1);
can someone please help me?
You can store Objects in a shared object.
Following your example, this may look as follows:
lvl1Score.data.score5 = { score: 2, profileName: "some_score" };

How to merge the contents of two variables

I have many string variables that start with "Question" and then end with a number. ("Question1")
Each variable has a question in it ("How many times does it say E?")
There is an editable textbox on the stage that the user types in which question number he want to be displayed in a different textbox. ("1")
When the user clicks a button, I want that the text of Question1 should be displayed in the textbox.
My code looks like this:
var Question1:String = "How many times does it say E?" ;
var Question2:String = "How many times does it say B?" ;
var Question3:String = "How many times does it say A?" ;
myButton.addEventListener(MouseEvent.CLICK, displayQuestion);
function displayQuestion(event:MouseEvent):void
{
var QuestionNumber:Number = Number(userInputQuestionNumber.text);
textBoxDisplayQuestion.text= Question(QuestionNumber);
}
How can I get the textBoxDisplayQuestion to display the actual text of the Question??
(the code i have now obviously is not working!!)
But this example doesnt seem to work: I created a class called Question and here is the code:
import Question;
var QuNoLoad:Number;
var Qu1:Question = new Question(1,"how","yes","no","maybe","so","AnsB","AnsA");
trace(Qu1.QuNo, Qu1.Qu, Qu1.AnsA,Qu1.AnsB, Qu1.AnsC, Qu1.AnsD, Qu1.CorAns, Qu1.FaCorAns);
//the following is the code for the button
loadQu.addEventListener(MouseEvent.CLICK, loadQuClick);
function loadQuClick(event:MouseEvent):void
{
//this sets the variable "QuNoLoad" with the contents of the "textBoxQuLoad"
//imagine the user inputed "1"
QuNoLoad=Number(textBoxQuLoad.text);
//this SHOULD!! display the contents of "Qu1.Qu"
textQu.text= this["Qu"+QuNoLoad.toString()+".Qu"]
//and when i traced this statment the value was "undefined"
}
Why???
You can reference a variable by name using square brackets [] operator, such as:
this["Question" + QuestionNumber.toString()]
You may use this operator to dynamically set and retrieve values for a property of an object.
Keeping the question number as an integer, your function would be:
var Question1:String = "How many times does it say E?" ;
var Question2:String = "How many times does it say B?" ;
var Question3:String = "How many times does it say A?" ;
function displayQuestion(event:MouseEvent):void
{
var QuestionNumber:uint = uint(userInputQuestionNumber.text);
textBoxDisplayQuestion.text = this["Question" + QuestionNumber.toString()];
}
This is a pretty fundamental concept in programming that will make a lot of things harder to do until you understand it well, and it's pretty hard to explain without starting with some groundwork:
What's happening here is easiest to talk about with plain old Object rather than classes, so lets start with a very simple example:
var question1:Object = new Object();
question1.number = 1;
Note that with Object you didn't have to say that number existed ahead of time, it gets created when you set it. Now, when you say either question1.number you get 1, obviously. What is happening, however is that first question1 gets the value you stored in the variable question1 (which is { number: 1 }), then the .number gets the value stored in the property number stored in that value: 1.
To save some typing, you can use a shorthand called "object literals":
var question1 = {
number: 1
};
Now lets try a more complex object:
var question1 = {
number: 1,
text: "How many times does it say A?",
answers: {
a: 1,
b: 2,
c: 3,
d: 4,
correct: "b"
}
};
Now question1 is an object that has 3 properties, one of which, answers, is an object with 5 properties: a, b, c, d, and correct. This could also be written as:
var question1 = new Object();
question1.number = 1;
question1.text = "How many times does it say A?";
question1.answers = new Object();
question1.answers.a = 1;
question1.answers.b = 2;
question1.answers.c = 3;
question1.answers.d = 4;
question1.answers.correct = "b";
It should be pretty clear why the literal syntax exists now!
This time, if you say question1.answers.correct you get "b": first question1 gets you the { number: 1,...} value, then the .answers gets the { a: 1, b: 2,...} value, then finally the .correct gets the "b" value.
You should also know that this is a special variable that has a particular meaning in ActionScript (and JavaScript, on which it is based): it broadly refers to the object in when the code you are writing is inside: for "global" code (not inside a function), var adds properties to this object: var number = 2; and this.number = 2 are this same here. (This is not true when you're in function, this behaves differently there, sometimes in very strange ways, so be careful!)
Now you might start seeing what's happening: when you use [], for example, question1["number"], rather than question1.number, you are passing the property name you want to get as a String value, which means you can change what property you get while you are running, rather than when you compile ("runtime" vs. "compiletime"), but it also lets you get properties with names you can't refer to with the . syntax!
var strange = {
"a strange name? That's OK!": 1
};
trace(strange["a strange name? That's OK!"]);
So when you write this["Qu" + QuNoLoad.toString() + ".QuNo"], you create a name like "Qu2.QuNo", for example, you are trying to get a property with that exact name, . included, which doesn't exist! What you were trying to do the equivalent of: Qu2.QuNo could be written as this["Qu" + QuNoLoad].QuNo.
I shouldn't leave this without saying, though, that for something like this, I would use arrays, which exist so that you can use a single name to store a list of values:
var questions:Array = [ // set questions to an array with multiple questions
new Question(...),
new Question(...),
...
];
for each (var question:Question in questions) { // Look at each question in the array
if (question.QuNo == textBoxQuLoad.text) { // If this is the right question
loadQuestion(question);
break; // Found it, stop looking at each question by "breaking out" of the for each
}
}
There's lots more you can do with arrays, so read up on them when you get time.

AdvancedDataGrid total sum of branch nodes

Introduction:
I have an AdvancedDataGrid displaying hierarchical data illustrated by the image below:
The branch nodes "Prosjekt" and "Tiltak" display the sum of the leaf nodes below.
Problem: I want the root node "Tavle" to display the total sum of the branch nodes below. When i attempted to do this by adding the same SummaryRow the sum of the root node was not calculcated correctly(Every node's sum was calculated twice).
dg_Teknikktavles = new AutoSizingAdvancedDataGrid();
dg_Teknikktavles.sortExpertMode="true";
dg_Teknikktavles.headerHeight = 50;
dg_Teknikktavles.variableRowHeight = true;
dg_Teknikktavles.addEventListener(ListEvent.ITEM_CLICK,dg_TeknikktavlesItemClicked);
dg_Teknikktavles.editable="false";
dg_Teknikktavles.percentWidth=100;
dg_Teknikktavles.minColumnWidth =0.8;
dg_Teknikktavles.height = 1000;
var sumFieldArray:Array = new Array(context.brukerList.length);
for(var i:int = 0; i < context.brukerList.length; i++)
{
var sumField:SummaryField2 = new SummaryField2();
sumField.dataField = Ressurstavle.ressursKey + i;
sumField.summaryOperation = "SUM";
sumFieldArray[i] = sumField;
}
var summaryRow:SummaryRow = new SummaryRow();
summaryRow.summaryPlacement = "group";
summaryRow.fields = sumFieldArray;
var summaryRow2:SummaryRow = new SummaryRow();
summaryRow2.summaryPlacement = "group";
summaryRow2.fields = sumFieldArray;
var groupField1:GroupingField = new GroupingField();
groupField1.name = "tavle";
//groupField1.summaries = [summaryRow2];
var groupField2:GroupingField = new GroupingField();
groupField2.name = "kategori";
groupField2.summaries = [summaryRow];
var group:Grouping = new Grouping();
group.fields = [groupField1, groupField2];
var groupCol:GroupingCollection2 = new GroupingCollection2();
groupCol.source = ressursTavle;
groupCol.grouping = group;
groupCol.refresh();
Main Question: How do i get my AdvancedDataGrid's (dg_Teknikktavles) root node "Tavle" to correctly display the sum of the two branch nodes below?
Side Question: How do i add a red color to the numbers of the root node's summary row that exceed 5? E.g the column displaying 8 will exceed 5 in the root node's summary row, and should therefore be marked red
Thanks in advance!
This is a general answer, without code examples, but I had to do the same just couple of days ago, so my memory is still fresh :) Here's what I did:
Created a class A to represent an item renderer data, extended it from Proxy (I had field names defined at run time), and let it contain a collection of values as it's data member. Once accessed through flash_proxy::getPropery(fieldName) it would find a corresponding value in the data member containing the values and return it. Special note: implement IUID, just do it, it'll save you couple of days of frustration.
Extended A in B, added a children property containing ArrayCollection of A (don't try to experiment with other collection types, unless you want to find yourself examining tons of framework code, trust me, it's ugly and is impossible to identify as interesting). Let B override flash_proxy::getPropery - depending of your compiler this may, or may not be possible, if not possible - call some function from A.flash_proxy::getPropery() that you can override in B. Let this function query every instance of A, which is a child of B, asking the same thing, as DataGrid itself would, when building item renderers - this way you would get the total.
When creating a data provider. Create an ArrayCollection of B (again, don't try to experiment with other collections--unless you are ready for lots of frustration). Create Hierarchical data that uses this array collection as a source.
Colors - that's what you use item renderers for, just look up any tutorial on using item renderers, that must be pretty basic.
In case someone else has the same problem:
The initial problem that everything was summed twice, was the result of using the same Array of SummaryField2 (sumFieldArray in the code) for both grouping fields(GropingField2 tavle and kategori)
The Solution to the main question: was to create a new array of summaryfields for the root node(in my intial for loop):
//Summary fields for root node
var sumFieldRoot:SummaryField2 = new SummaryField2();
sumFieldRoot.dataField = Ressurstavle.ressursKey + i;
sumFieldRoot.summaryOperation = "SUM";
sumFieldArrayRoot[i] = sumFieldRoot;
Answer to the side question:
This was pretty much as easy as pointed out by wvxyw. Code for this solution below:
private function summary_styleFunction(data:Object, col:AdvancedDataGridColumn):Object
{
var output:Object;
var field:String = col.dataField;
if ( data.children != null )
{
if(data[field] >5){
output = {color:0xFF0000, fontWeight:"bold"}
}
else {
output = {color:0x006633, fontWeight:"bold"}
}
//output = {color:0x081EA6, fontWeight:"bold", fontSize:14}
}
return output;
}
