I am building facebook iframe app. When I load this section of code on browser.
In browsers console I seen the following to Errors
FB.init has already been called - this could indicate a problem
Invalid App Id: Must be a number or numeric string representing the application id.
Here is the sight of my code:
`script `<src="https://connect.facebook.net/en_US/all.js"> </script>`
FB.init({
appId : '<%= AppConfig.facebook_oauth[:application_id] %>',
cookie : true,

As said in the title, I'm using Django, GraphQL, Apollo and VueJS in my project.
I'm developping it as a SPA (Single Page Application).
Everything works fine, until I hit the F5 button and refresh the page. Indeed, it shows an unknown page. The thing is it is VueRouter that is managing the SPA and it works fine. But when I press F5, that is Django that tries to serve a page for the current URL and since it doesn't know it, it can't serve the appropriate page.
I know I can set the VueRouter 'history' mode, which I did, and add a URL to Django that serves index.html whatever the URL is.
My problem is the following :
When I'm on a particular form view (i.e : a User form view) my URL is the following :
http://localhost:8000/user
Since I'm using GraphQL for my API, the retrieved data is not based on the URL. In fact, that is my VueJS component that says : Hey Apollo, run that GraphQL to retrieve the User I want.
So when I refresh, yes it serves the User form view..but empty.
The question is : How could I solve this ?
For clarification purposes, here are some code samples :
My Django URLs :
# (... other imports here ...)
from .schema import schema
urlpatterns = [
path('admin/', admin.site.urls),
path('graphql', csrf_exempt(GraphQLView.as_view(graphiql=True, schema=schema))), # 'schema' is the main GraphQL schema
path('', TemplateView.as_view(template_name='index.html')),
re_path(r'^.*$', TemplateView.as_view(template_name='index.html')) # I saw that many times to serve the page whatever the URL is when refreshing the page
]
My Vue Router :
export default new Router({
mode: 'history',
routes: [
{ path: '/', name: 'MainApp' },
// ...
{ path: '/users', name: 'UserList', component: UserList },
{ path: '/user/create', name: 'UserFormCreate', component: UserForm, props: true },
{ path: '/user', name: 'UserFormView', component: UserForm, props: true },
{ path: '/user/edit', name: 'UserFormEdit', component: UserForm, props: true },
// Same pattern for other models like 'Group' ...
]
My Example VueJS Component :
<script>
import {
// ...
USER_QUERY,
// ...
} from '../../graphql/base/user.js'
export default {
name: 'UserForm',
props: {
userId: Number,
editing: {
type: Boolean,
default: false
}
},
apollo: {
user: {
query: USER_QUERY,
variables () { return { id: this.userId } },
skip () { return this.userId === undefined },
result ({ data }) {
this.form.username = data.user.username
this.form.firstName = data.user.firstName
this.form.lastName = data.user.lastName
}
}
},
data () {
return {
form: {
username: '',
password: '',
firstName: '',
lastName: ''
},
// ...
}
},
methods: {
// ...
}
I have to mention that I've seen more or less related topics but that doesn't solve my problem.
Thanks in advance for your help !
Edit your route paths to use params. For example:
{ path: '/user/:userId', name: 'UserFormView', component: UserForm, props: true }
Now, the app will interpret any number following the user/ path as a prop called userId. (props: true is important here for using the params as props.)
The only other change you need to make is adjusting your router-links to include the id as well (Ex.: http://localhost:8000/user/1) so that when the page is refreshed, there will be a param to read.
When using the Google Custom App Publishing API from my NodeJS, I encounter an error
config: [Object: Inspection interrupted prematurely. Maximum call stack size exceeded.],
code: 403,
errors: [
{
domain: 'global',
reason: 'forbidden',
message: 'apkInvalidFile'
}
]
And no much more details about it.
There is a very precise way to create this request. The right way is not documented anywhere and requires some retro-engineering.
Here is what works:
result = await getPlayCustomApp().accounts.customApps.create({
account: 'FIXME entreprise developer account id',
requestBody: {
title: 'Trololo app title',
languageCode: 'en_US',
},
media: {
body: fs.createReadStream('/path/to/app.apk'),
},
});
I hope it helps people not waste their afternoon!
I am working on my first Ember app and got it to display the way I wanted with the route returning a static JSON object from model():
element: {
name: "First Element",
divisions: [{
name: "First Division",
sets: [{name: "Set 1"},{name: "Set 2"},{name: "Set 3"}]
}, {
name: "Second Division",
sets: [{name: "Set 1"},{name: "Set 2"},{name: "Set 3"}]
}]
}
Now I am trying to refactor to use Ember Data + Mirage and having an awful time.
Here’s my index.js route
export default Ember.Route.extend({
model() {
return this.store.find('element', 1);
},
If I set up my Mirage config.js like this:
this.get('/elements', function() {
return {
elements: [
{
id: 1,
name: 'First Element',
divisions: [1, 2]
}
]
}
});
then I get this error:
Your Ember app tried to GET '/elements/1', but there was no route defined to handle this request.
If I set up my Mirage config.js like this:
this.get('/elements/1', function() {
return {
id: 1,
name: 'First Element',
divisions: [1, 2]
}
});
then I get this error:
22:46:40.883 "Error while processing route: index" "Assertion Failed: normalizeResponse must return a valid JSON API document:
* One or more of the following keys must be present: "data", "errors", "meta"." "EmberError#http://localhost:4200/assets/vendor.js:25582:15
EDIT:
So this isn't a solution to the problem as stated but it got me past this. I gave up on Pretender and started again creating an actual Rails server according to this excellent tutorial: http://emberigniter.com/modern-bridge-ember-and-rails-5-with-json-api/
I was able to do everything I wanted this way and if I ever want to make this a production app, I'm a lot closer.
So the issue is that you aren't actually adhering to the JSON API specification. You can solve this by reading Mirage's page on how to conform.
Essentially you need to either be returning an object at the top level of your JSON response in the case of a GET /foo/1 call. You'll also need to change your "elements" attribute to "data" for GET /foo and that should do the trick. Right now there isn't a simple, re-usable way to do this Mirage out of the box. The best bet right now for both issues is to use the solution presented in this issue.
ember error normalizeResponse must return a valid JSON API document
can be fixed in three ways
return a valid JSONAPI response
see your error message:
normalizeResponse must return a valid JSON API document:
* One or more of the following keys must be present: "data", "errors", "meta".
this.get('/elements/1', function() {
return {
data: {
id: 1,
name: 'First Element',
divisions: [1, 2]
}
}
});
see also https://jsonapi.org/examples/
normalize all responses
// app/serializers/application.js
import EmberData from "ember-data";
export default EmberData.JSONAPISerializer.extend({
normalizeResponse() {
return {
data: this._super(...arguments),
};
},
//normalize(){},
//serialize(){},
// ...
});
problem: error handling
by wrapping all responses in { data: ... }, they never return errors
on errors, the response should be
this.get('/elements/1', function() {
return {
errors: [
{
id: 12345,
title: 'title for error #12345'
}
]
}
});

duplicate: How can ember application be integrated to use with json-server?
I´ve never work with JSON before, but have with xml, php, mysql. I have a populated database on the server and would like to develop a web application with ember.js to interact with this data (CRUD).
Where should I start? I know ember-data has most of the things I would need when developing, but I'm unsure of how to start.
Since the database holds different tables, is it possible to keep this information in one json file? is it the appropriate way to do it? How do I automatically produce this json file from the server?
you can start with a read query :
You upload a file sample with the json syntaxe on your server (or use your json service if it's enable) to start quickly. Test that you can access to it in your browser, for example :
[ {"id": 1, "desc": "hmarchadour"}, {"id": 2, "desc": "moderator"} ]
Well now you take/create a view in your embjer js and you can use JQuery to call this file/service :
Ember.View.create({
templateName : "templateName" // you
stuff : [],
didInsertElement : function() {
$.ajax({
type : "GET",
url : <url-of-your-sample>,
dataType: "json",
success : function(result) {
var tmpStuff = json2Stuff(result);
this.set('stuff', tmpStuff);
},
error : ... }
);
}
});
Regards,
I started playing a bit with Sencha Touch.
So I've built a really simple application based on one of the examples just to see how it goes.
Basically it creates a JSON Request which executes a Last.FM web service to get music events near the user's location.
Here's the JSON code:
var makeJSONPRequest = function() {
Ext.util.JSONP.request({
url: 'http://ws.audioscrobbler.com/2.0/',
params: {
method: 'geo.getEvents',
location: 'São+Paulo+-+SP',
format: 'json',
callback: 'callback',
api_key: 'b25b959554ed76058ac220b7b2e0a026'
},
callback: function(result) {
var events = result.data.events;
if (events) {
var html = tpl.applyTemplate(events);
Ext.getCmp('content').update(html);
}
else {
alert('There was an error retrieving the events.');
}
Ext.getCmp('status').setTitle('Events in Sao Paulo, SP');
}
})
};
But every time I try to run it, I get the following exception:
Uncaught SyntaxError: Unexpected token :
Anyone has a clue?
A couple of things. First of all the "Uncaught SyntaxError: Unexpected token :" means the browser javascript engine is complaining about a colon ":" that has been put in the wrong place.
The problem will most likely be in the returned JSON. Since whatever the server returns will be run though the eval("{JSON HTTP RESULT}") function in javascript, the most likely thing is that your problem is in there somewhere.
I've put your code on a little sencha test harness and found a couple of problems with it.
First: My browser was not too happy with the "squiggly ã" in location: 'São+Paulo+-+SP', so I had to change this to location: 'Sao+Paulo,+Brazil', which worked and returned the correct results from the audioscribbler API.
Second: I notice you added a callback: 'callback', line to your request parameters, which changes the nature of the HTTP result and returns the JSON as follows:
callback({ // a function call "callback(" gets added here
"events":{
"event":[
{
"id":"1713341",
"title":"Skank",
"artists":{
"artist":"Skank",
"headliner":"Skank"
},
// blah blah more stuff
"#attr":{
"location":"Sao Paulo, Brazil",
"page":"1",
"totalpages":"1",
"total":"2"
}
}
}) // the object gets wrapped with extra parenthesis here
Instead of doing that I think you should be using the callbackKey: 'callback' that comes with the example in http://dev.sencha.com/deploy/touch/examples/ajax/index.js.
Something like this for example:
Ext.util.JSONP.request({
url: 'http://ws.audioscrobbler.com/2.0/',
params: {
method: 'geo.getEvents',
location: 'Sao+Paulo,+Brazil',
format: 'json',
api_key: 'b25b959554ed76058ac220b7b2e0a026'
},
callbackKey: 'callback',
callback: function(result) {
// Output result to console (Firebug/Chrome/Safari)
console.log(result);
// Handle error logic
if (result.error) {
alert(result.error)
return;
}
// Continue your code
var events = result.data.events;
// ...
}
});
That worked for me so hopefully it'll work for you too. Cherio.
