Json data returned from my ASP.NET core server with:
JsonConvert.SerializeObject(categories.Select(t => new { id = t.Id.ToString(), text = t.Name.ToLower() }))
Looks:
[
{
"id": "7929d7ad-c7c3-45c5-b749-7633a478d55c",
"text": "apparel"
},
{
"id": "e551cbc2-9069-4c99-a66b-5824ec2610b2",
"text": "electronics"
}]
But I want result like:
{"results":[
{
"id": "7929d7ad-c7c3-45c5-b749-7633a478d55c",
"text": "apparel"
},
{
"id": "e551cbc2-9069-4c99-a66b-5824ec2610b2",
"text": "electronics"
}]}
for select2. How can I achieve that?
try this
JsonConvert.SerializeObject( new {
results = categories.Select(t => new { id = t.Id.ToString(), text = t.Name.ToLower() })
} );

I am using Microsoft Bot Framework for my facebook messenger bot. I want to load the dialog data from json files instead of hard coding in the js file. I would like to configure the next step in the dialog, based on result from the "current" step, which is part of the json file configuration, something like this.
{
"name": "welcome",
"type": "waterfall",
"steps": [
{
"id": 0,
"data": [
{
"type": "text",
"value": "Hey, It's nice to meet you."
},
{
"type": "quickReplies",
"value": "What do you want to do next?",
"options": [
{
"text": "some option 1",
"value": "option1"
},
{
"text": "some option 2",
"value": "option2"
}
]
}
],
"next": [
{
"result": "option1",
"action": "goto step 2"
},
{
"result": "option2",
"action": "goto step 5"
}
]
}
]
}
I would like to process all the incoming messages and respond with correct dialog or correct step in the dialog for the user.
I am trying something like this;
handleMessage = function (session) {
var step = session.dialogData["BotBuilder.Data.WaterfallStep"] || 0;
// check response data from previou step and identify the next step.
// set the waterfall step id
session.dialogData["BotBuilder.Data.WaterfallStep"] = 2;
session.send("Hello");
}
var bot = new builder.UniversalBot(connector, function (session) {
handleMessage(session);
})
.set('storage',tableStorage);
With this code, I am always getting step as zero for session.dialogData["BotBuilder.Data.WaterfallStep"] even after setting this to a different number.
Also, as soon as I set the waterfall step number, all other state data that is stored in my table storage for this conversation is gone.
Storage data before setting waterfall step:
{
"BotBuilder.Data.SessionState": {
"callstack": [
{
"id": "*:/",
"state": {
"BotBuilder.Data.WaterfallStep": 0
}
},
{
"id": "*:welcome",
"state": {
"BotBuilder.Data.WaterfallStep": 1
}
},
{
"id": "BotBuilder:prompt-text",
"state": {
"options": {
"prompt": {
"type": "message",
"agent": "botbuilder",
"source": "facebook",
"address": {
"id": "mid.$cAAAlr-0LRH9niO21L1hV6hs83GuJ",
"channelId": "facebook",
"user": {
"id": "XXXX",
"name": "XXXX"
},
"conversation": {
"isGroup": false,
"id": "XX"
},
"bot": {
"id": "XXX",
"name": "XXX"
},
"serviceUrl": "https://facebook.botframework.com"
},
"text": "what do you want to next"
//ignored for simplicity
},
"promptAfterAction": true,
"libraryNamespace": "*"
},
"turns": 0,
"lastTurn": 1517594116372,
"isReprompt": false
}
}
],
"lastAccess": 1517594112740,
"version": 0
}
}
After I set the waterfall step:
{
"BotBuilder.Data.SessionState": {
"callstack": [
{
"id": "*:/",
"state": {
"BotBuilder.Data.WaterfallStep": 2
}
}
],
"lastAccess": 1517602122416,
"version": 0
}
}
Interestingly the step number is saved to the database (but in session state) but my "session" variable do not have this value anywhere. Also, even after configuring custom state service, the serviceUrl is still https://facebook.botframework.com which I thought is the default state service used if there is no state service set for the bot.
Per your code, as your bot actually contains only one waterfall step: handleMessage(session);, which raised your issue. You can consider to create multiple dialogs from json configration instead of complex waterfall steps.
Here is my quick test, for your information:
const json = `
[{
"name": "welcome",
"type": "waterfall",
"steps": [
{
"id": 0,
"data": [
{
"type": "text",
"value": "Hey, It's nice to meet you."
},
{
"type": "quickReplies",
"value": "What do you want to do next?",
"options": [
{
"text": "some option 1",
"value": "option1"
},
{
"text": "some option 2",
"value": "option2"
}
]
}
],
"next": [
{
"result": "option1",
"action": "dialog2"
},
{
"result": "option2",
"action": "dialog3"
}
]
}
]
},{
"name":"dialog2",
"type": "waterfall",
"steps": [
{
"data": [
{
"type": "text",
"value": "Hey, this is dialig2."
}]
}
]
},{
"name":"dialog3",
"type": "waterfall",
"steps": [
{
"data": [
{
"type": "text",
"value": "Hey, this is dialig3."
}]
}
]
}]
`;
const generateSignleStep = (step) => {
return (session, args, next) => {
step.forEach(sentence => {
switch (sentence.type) {
case 'quickReplies':
let choices = sentence.options.map(item => {
return item.value
});
let card = new builder.ThumbnailCard(session)
.text(sentence.value)
.buttons(sentence.options.map(choice => new builder.CardAction.imBack(session, choice.value, choice.text)))
let message = new builder.Message(session).addAttachment(card);
builder.Prompts.choice(session, message, choices);
break;
case 'text':
default:
session.send(sentence.value)
break;
}
})
}
}
const generatenextAction = (actions) => {
return (session, args, next) => {
const response = args.response;
actions.map(action => {
if (action.result == response.entity) {
session.beginDialog(action.action);
}
})
}
}
const generateWaterfallSteps = (steps) => {
let waterfall = [];
steps.forEach(step => {
waterfall.push(generateSignleStep(step.data));
if (step.next) {
waterfall.push(generatenextAction(step.next));
}
});
return waterfall;
}
var bot = new builder.UniversalBot(connector);
const jsonobj = JSON.parse(json);
jsonobj.forEach(dialog => {
bot.dialog(dialog.name, generateWaterfallSteps(dialog.steps))
.triggerAction({
matches: new RegExp(dialog.name, "g")
})
});
The result is:
Using: MongoDB and native nodeJS mongoDB driver.
I'm trying to parse all the data from fb graph api, send it to my API and then save it to my DB.
PUT handling in my server:
//Update user's data
app.put('/api/users/:fbuser_id/:category', function(req, res) {
var body = JSON.stringify(req.body);
var rep = /"data":/;
body = body.replace(rep, '"' + req.params.category + '"' + ':');
req.body = JSON.parse(body);
db.fbusers.update({
id: req.params.fbuser_id
}, {
$set: req.body
}, {
safe: true,
multi: false
},
function(e, result) {
if (e) return next(e)
res.send((result === 1) ? {
msg: 'success'
} : {
msg: 'error'
})
});
});
I'm sending 25 elements at a time, and this code just overrides instead of updating the document.
Data I'm sending to the API:
{
"data": [
{
"category": "App page",
"name": "SoundCloud",
"id": "7919071058",
"created_time": "2013-09-16T18:16:59+0000"
},
{
...and so on
}
]
}
Basically my API changes "data" key from sent json to the category name, f.e.:
PUT to /api/users/000/likes will change the "data" key to "likes":
{
"likes": [
{
"category": "App page",
"name": "SoundCloud",
"id": "7919071058",
"created_time": "2013-09-16T18:16:59+0000"
},
{
...and so on
}
]
}
Then this JSON is put to the db.
Hierarchy in mongodb:
{
"_id": ObjectID("556584c8e908f0042836edce"),
"id": "0000000000000",
"email": "XXXX#gmail.com",
"first_name": "XXXXXXXX",
"gender": "male",
"last_name": "XXXXXXXXXX",
"link": "https://www.facebook.com/app_scoped_user_id/0000000000000/",
"locale": "en_US",
"name": "XXXXXXXXXX XXXXXXXXXX",
"timezone": 3,
"updated_time": "2015-05-26T18:11:59+0000",
"verified": true,
"likes": [
{
"category": "App page",
"name": "SoundCloud",
"id": "7919071058",
"created_time": "2013-09-16T18:16:59+0000"
},
{
"category": "App page",
"name": "SoundCloud",
"id": "7919071058",
"created_time": "2013-09-16T18:16:59+0000"
},
{
....and so on
}
]
}
So the problem is that my api overrides the field (in this case "likes") with newly sent data, instead of appending it to already existing data document.
I am pretty sure that I should be using other parameter than "$put" in the update, however, I have no idea which one and how to pass parameters to it programatically.
Use $push with the $each modifier to append multiple values to the array field.
var newLikes = [
{/* new item here */},
{/* new item here */},
{/* new item here */},
];
db.fbusers.update(
{ _id: req.params.fbuser_id },
{ $push: { likes: { $each: newLikes } } }
);
See also the $addToSet operator, it adds a value to an array unless the value is already present, in which case $addToSet does nothing to that array.
I am new to AngularJS and trying to create a $scope for tracks for later usage
data.json (sample):
[
{
"album": "Album name",
"tracks": [
{
"id": "1",
"title": "songtitle1",
"lyric": "lyrics1"
},
{
"id": "2",
"title": "songtitle2",
"lyric": "lyrics2"
}
]
}
]
Controller
app.controller('lyricsCtrl', function($scope, $http) {
$http.get('data.json')
.then(function(result) {
$scope.albums = result.data;
$scope.tracks = result.data.tracks;
console.log($scope.tracks); //Undefined...
});
});
Why is $scope.tracks undefined?
If your json file is as is:
[
{
"album": "Album name",
"tracks": [
{
"id": "1",
"title": "songtitle1",
"lyric": "lyrics1"
},
{
"id": "2",
"title": "songtitle2",
"lyric": "lyrics2"
}
]
}
]
We have a response of:
data: Array[1]
0: Object
album: "Album name"
tracks: Array[2]
Since data is returned as an array you would handle like any other javascript array and access by index, so you could do a loop or if you know only 1 result is going to be returned you could use the zero index:
$http.get('data.json').then(function(result) {
console.log(result);
// Assign variables
$scope.album = result.data[0].album;
$scope.tracks = result.data[0].tracks;
for (var i = 0, l = $scope.tracks.length; i < l; i++) {
console.log($scope.tracks[i].title);
}
});
result.data is an array,So you must have to use index to access its child like:-
$scope.tracks = result.data[0].tracks;
It should be result.data[0].tracks as data is an array
$scope.tracks = result.data[0].tracks;
My json data is as follows:
"query": {
"count": 1,
"url": [
{
"execution-start-time": "1"
},
{
"execution-time": "745"
}
],
"service-time": "1481"
},
results": {
"div": {
"class": "makers",
"ul": {
"li": [
{
"a": {
"href": "nokia_x2_dual_sim-6383.php",
"img": {
"src": "Nokia-X2-Dual-SIM.jpg"
},
"strong": {
"br": null,
"content": "Nokia\nX2 Dual SIM"
}
}
},
{
"a": {
"href": "nokia_xl-6148.php",
"img": {
"src": "nokia-xl.jpg",
},
"strong": {
"br": null,
"content": "Nokia\nXL"
}
}
}
]
Now I want to extract the "content" part from this json data using jsonpath.I am using jsonpath-0.8.0.js for this purpose.
I have tried to parse the json data in the following way:
function ParseData(data) {
var result = jsonPath(data, "$.query.results[*].ul.li[*].strong.content");
$('#carousel').empty();
var html = "";
for (i = 0; i < result.length; i++) {
// do something
}
and I was expecting to get Nokia\nX2 Dual SIM and Nokia\nXL as output but this code of mine does not return anything.I cannot understand the problem.
How do I extract the content data from this json? please help.
Friends, I finally got the answer to my problem.I used the following code to extract content from the above given json data.
var result = jsonPath(data, "$.query.results[*].ul.li[*].a.strong.content");
Now I am getting the output data as expected.
I am using loopjs tokeninput in a View. In this scenario I need to prePopulate the control with AdminNames for a given Distributor.
Code Follows :
$.getJSON("#Url.Action("SearchCMSAdmins")", function (data) {
var json=eval("("+data+")"); //doesnt work
var json = {
"users": [
eval("("+data+")") //need help in this part
]
}
});
$("#DistributorCMSAdmin").tokenInput("#Url.Action("SearchWithName")", {
theme: "facebook",
preventDuplicates: true,
prePopulate: json.users
});
There is successful return of json values to the below function. I need the json in the below format:
var json = {
"users":
[
{ "id": "1", "name": "USER1" },
{ "id": "2", "name": "USER2" },
{ "id": "3", "name": "USER3" }
]
}
