In my Dasha.ai code, I want to send dynamic variables to phrasemap.json. How can I send dynamic data to phrasemap if possible?
To dynamic phrase you should will do:
In file "main.dsl" in context section create new variable (as example - "your_variable_phrase")
context
{
input your_variable_phrase: string;
}
and then Dasha will say variable phrases for 2 ways:
First.
Use command "sayText" - to say something without phrasemap file.
In section "do"
#sayText($your_variable_phrase)
Second. Use phrasemap.
In the main.dsl in section "do"
#say("greeting",
{
your_variable_phrase: $your_variable_phrase
}
);
In phrasemap file:
"greeting": {
"first": [
{
"text": "Hello "},
{ "id": "your_variable_phrase", "type": "dynamic" }
],

I've been wondering for some days what kind of scheme would be more appropriate to use a data list in json in a web application.
I'm developing a REST Web Application, and im using Angular for front end, i should order, filter and print these data list also in xml ...
For you what scheme is better and why?
1) {
"datas": [
{ "first":"","second":""},
{ "first":"","second":""},
{ "first":"","second":""}
]
}
2) {
"datas": [{
"data": { "first":"","second":""},
"data": { "first":"","second":""},
"data": { "first":"","second":""}
}]
}
3) [
{ "first":"","second":""},
{ "first":"","second":""},
{ "first":"","second":""}
]
Thanks so much.
The first and third notations are quite similar because the third notation is included in your first.
So the question is "Should I return my datas as an array or should I return an object with a property that contain the array ?
It will depend on either you want to have more information alongside your datas or not.
For exemple, if your API might return an error, you will want to manage it from the front end.
In case of error, the JSON will looks like this :
{
"datas": null,
"error": "An error occured because of some reasons..."
}
At the opposite, if everything goes well and your API actually return the results, it will looks like this :
{
"datas": [
{ "first":"","second":""},
{ "first":"","second":""},
{ "first":"","second":""}
],
"error": null
}
Then your front end can use the error property to manage errors sent from the API.
var result = getDatas(); // Load datas from the API
if(result.error){
// Handle the error, display a message to the user, ...
} else {
doSomething(result.datas); // Use your datas
}
If you don't need to have extra properties like error then you can stick with the third schema.
The second notation is invalid. The datas array will contain only one object which will have one property named data. In this case data is a property that is defined multiple times so the object in the array will contain only the last occurence:
var result = {
"datas": [{
"data": { "first":"a","second":"b"},
"data": { "first":"c","second":"d"},
"data": { "first":"e","second":"f"}
}]
}
console.log("Content of result.datas[0].data : ")
console.log(result.datas[0].data)
Obviously the first option would be easy to use. Once you will access datas it'll give you an array. Any operation (filter, sort, print) on that array will be easy in comparison to anything else. Everywhere you just need to pass datas not datas.data.
I'm looking for a way to pass a variable (normal string) from a linked template back up to my main template.
I want to use something like: (in linked template)
"outputs": {
"installStringNodes": {
"type": "string",
"value": "[variables('installString').value]"
}
}
And then i want to call this variable into my main template. But i can't seem to crack how.
"variables":{
"installStringFromNodeResources": {
"value": "[??('node-resources')??.outputs.installStringNodes.value]"
},
}
There's a 'sharing state in resource manager templates' doc with the usage of reference() but apparently that can't be used in variables as it gives me an error while trying to deploy.
Seems to me there should be an easy solution for this but i haven't been able to see it yet..
In the main template, the variable should be:
"installStringFromNodeResources": {
"value": "[reference('node-resources').outputs.installStringNodes.value]"
}
Follow this walk through sharing state between templates
Say I have a json structure like so:
{
"A":{
"name":"dog",
"foo":"bar",
"array":[
{"name":"one"},
{"name":"two"}
]
},
"B":{
"name":"cat",
"foo":"bar",
"array":[
{"name":"one"},
{"name":"three"}
]
}
}
I want to be able to do two things.
1: Query for any "name":* within "A.array".
2: Query for any "name":"one" within "*.array".
That is, any object within a specific document's array, and any specific object within any document's array.
I hope I have used proper terminology here, I am just starting to familiarize myself with a lot of these concepts. I have tried searching for an answer but am having trouble finding something like my case.
Thanks.
EDIT:
Since I still haven't really made progress towards this, I'll just explain what I'm trying to do: I want to use the "AllSets" dataset (after I trim it down below 16mb) available on mtgjson.com. I am having problems getting mongo to play nicely though.
In an effort to try and learn what's going on, I have downloaded one set: http://mtgjson.com/json/OGW.json.
Here is a photo of its structure laid out:
I am unable to even get mongo to return an object from within the cards array using:
"find({cards: {$elemMatch: {name:"Deceiver of Form"}}})"
"find({"cards.name":"Deceiver of Form"})"
When I run either of the commands above it just returns the entire document to me.
You could use the positional projection $ operator to limit the contents of an array. For example, if you have a single document like below:
{
"block": "Battle for Zendikar",
"booster": "...",
"translations": "...",
"cards": [
{
"name": "Deceiver of Form",
"power": "8"
},
{
"name": "Eldrazi Mimic",
"power": "2"
},
{
"name": "Kozilek, the Great Distortion",
"power": "12"
}
]
}
You can query for a card name matching "Deceiver of Form", and limit fields to return only the matching array card element(s) using:
> db.collection.find({"cards.name":"Deceiver of Form"}, {"cards.$":1})
{
"_id": ObjectId("..."),
"cards": [
{
"name": "Deceiver of Form",
"power": "8"
}
]
}
Having said the above, I think you should re-consider your data model. MongoDB is a document-oriented database. A record in MongoDB is a document, so having a single record in a database does not bring out the potential of the database i.e. similar to storing all data in a single row in a table.
You should try storing the 'cards' into a collection instead. Where each document is a single card, (depending on your use case) you could add a reference to another collection containing the deck information. i.e: block, type, releaseDate, etc. For example:
// a document in cards collection:
{
"name": "Deceiver of Form",
"power": "8",
"deck_id": 1
}
// a document in decks collection:
{
"deck_id": 1,
"releaseDate": "2016-01-22",
"type": "expansion"
}
For different types of data model designs and examples, please see Data Model Design.
Let's say this is the table inside my collection:
{
"_id" : ObjectId("557cf6bbd8efe38c627bffdf"),
"name" : "John Doe",
"rating" : 9,
"newF" : [
"milk",
"Eggs",
"Beans",
"Cream"
]
}
Once a user types in some input, it is sent to my node server, and my node server then adds that item to the list "newF", which is then sent back to my MongoDB and saved.
I'm trying to use update, which can successfully change the values inside of this table, but I'm not sure how to add new items onto that list. I did it with $push inside the MongoDB shell, but not sure how to do it on node.
Here's a snippet of my code:
db.collection('connlist').update({ _id: new ObjectId("e57cf6bb28efe38c6a7bf6df")}, { name: "JohnDoe", rating: 9, newF: ["Milk, Eggs", "Beans"] }, function(err,doc){
console.log(doc);
});
Well the syntax for adding new items is just the same as in the shell:
// make sure you actually imported "ObjectID"
var ObjectId = require('mongodb').ObjectID;
db.collection('conlist').update(
{ "_id": new ObjectId("e57cf6bb28efe38c6a7bf6df") },
{ "$push": { "newF": { "$each": [ "cream", "butter" ] } } },
function(err,numAffected) {
// do something in the callback
}
)
Or perhaps use .findOneAndUpdate() if you want to return the modified document instead of just making the alteration.
Of course use $push and possibly with $each which allows multiple array elements to be added when adding to an array. If you want "unique" items then use $addToSet where your operation allows.
And generally speaking for other items you should use $set or other operators in the update portion of your document. Without these operators you are just "replacing" the document content with whatever structure you place in the "update" portion of your statement.
The problem is that in my app we have a data structure like this:
{
"adults": {
"jagger_mick_dateOfBirth": {
"name": "Mick"
"lastName": "Jagger",
"more atributes": ""
},
"jolie_angelina_dateOfBirth": : {
"name": "Angelina"
"lastName": "Jolie",
"more atributes": ""
}
},
"children": {
"osbourne_ozzy_dateOfBirth": : {
"name": "Ozzy"
"lastName": "Osbourne",
"more atributes": ""
}
}
}
As you can see, for each Adult & Children, we use a dynamic attribute to identify each object. BUT inside is the same object.
Right now I am in the process to generate JSON Schemas (v4) for this data structure.
My problem is i cannot find a property to evaluate dynamic attributes, althought the object is the same, just the key is different.
I know that it is bad coding, but it is possible to generate a JSON Schema (v4) to validate a dynamic attribute (key) ?
Thanks in advance.
P.D.
If you are wondering why we use this approach, is because we can access directly to the object, instead of search for it.
If your dynamic object attributes can be described with a regular expression, you can use patternProperties keyword.
