Ember-cli-mirage not showing any data with get - ember.js

I am learning Ember and I am getting stuck on making the mock api with ember-cli-mirage. I modified the config file as specified in the ember tutorial as well as on the ember-cli-mirage site, but everytime I hit the endpoint I get nothing. Here is my current config file
export default function() {
this.get('/api/users', function() {
return {
users: [
{id: 1, name: 'Zelda'},
{id: 2, name: 'Link'},
{id: 3, name: 'Epona'},
]
}
});
}
Like I said, when I go to /api/users it is just a blank page. Am I missing something here?
Thanks!

First thing first, install Ember inspector extension (for Chrome or Firefox) and look in the browser console to see if Mirage is giving you some errors. If nothing is written in there, you are not hitting the endpoint with your ember application. Basically, Mirage proxies all the request from your ember application.
So you need to generate a user model
ember g model user
and put in there the name attribute.
Create a route and in the model hook write
return this.get('store').findAll('user');
(look at the quick start tutorial if something is not clear)
So now, leveraging Ember Data, your app will request all users hitting on /users.
Now let's start with mirage, generate a mirage model
ember g mirage-model user
and follow the mirage quickstart, just adapt it to your needs :)
Start your application with ember s and you should see the request to /users.
If you want to put your api on the same domain, but with the /api prefix, then i suggest you to read about endpoint path customization

In app/mirage/config.js you can set up mock endpoints for your users:
export default function() {
this.get('/users');
this.post('/users');
this.put('/users/:id');
this.del('/users/:id');
}
You can set up your mock data by configuring fixtures in app/mirage/fixtures/users.js:
export default [
{id: 1, name: 'Zelda'},
{id: 2, name: 'Link'},
{id: 3, name: 'Epona'},
];

Mirage isn't an actual server, so you won't be able to hit the API from your browser directly. It's a mock server that lives in JavaScript memory, and is instantiated when your Ember app boots up.
To test out your mocks, have your Ember app make an API request, e.g.
// routes/application.js
export default Ember.Route.extend({
model() {
return Ember.$.getJSON('/api/users');
}
});
If everything's hooked up correctly, you should now see Mirage handling this request and logging the response data in your console.

Ember model host adapter not overiding mirage

I'm using Ember-cli-mirage to mock data. I want to slowly integrate parts of the production api which is located on my local machine at http://localhost:8000. Ember docs tell me that I should be able to set an adapter so I can have a different host for each model.
I have a customer model, and have setup ember-cli-mirage which is successfully serving data. The customer model is the first model I want to split out to localhost:8000.
I've setup adapters/customer.js with the following:
import DS from 'ember-data';
export default DS.RESTAdapter.extend( {
host: 'http://localhost:8000',
namespace: 'api/v1'
});
But when I make the call I'm getting an error:
Mirage: Error: Your Ember app tried to GET 'http://localhost:8000/api/v1/customers',
but there was no route defined to handle this request.
Define a route that matches this path in your
mirage/config.js file. Did you forget to add your namespace?
And my header inspector shows that customers is making the request to the mirage server:
Request URL:http://localhost:6543/customers
Request Method:GET
Status Code:304 Not Modified
Remote Address:[::1]:6543
I suspect it's something to do with my config/environment.js setup so I'm looking at a variation of https://github.com/samselikoff/ember-cli-mirage/issues/497#issuecomment-183458721 as a potential workaround. But I can't see why mirage won't accept the adapter overide.
Should have read back through the mirage docs for this one. There's a passthrough function that allows mirage to pass certain requests through to Ember bypassing mirage:
// mirage/config.js
import Mirage from 'ember-cli-mirage';
export default function() {
this.urlPrefix = 'http://localhost:8000';
this.namespace = '/api/v1';
// Requests for customers
this.get('/customers');
this.get('/customers/:id');
this.post('/customers');
this.del('/customers/:id');
this.patch('/customers/:id');
// Passthrough to Django API
this.passthrough('/customers');
}
To make this work in my application adapter I added:
// app/adapters/application.js
import DS from 'ember-data';
export default DS.RESTAdapter.extend({
host: 'http://localhost:8000',
namespace: 'api/v1'
});
If this helps you in any way feel free to give this answer an upvote :)

Ember CLI and Google Analytics

According to the docs, you just need to embed the analytics code and reopen the Router. The latter seems unclear to me.
I've placed the embedded code on index.html, then created the following
app/reopens/router.js
import Router from '../router';
Router.reopen({
notifyGoogleAnalytics: function() {
return ga('send', 'pageview', {
'page': this.get('url'),
'title': this.get('url')
});
}.on('didTransition')
});
app/app.js: Added the import...
import './reopens/router';
This results in a fatal error when viewing the site: Uncaught ReferenceError: ga is not defined
How do you make the ga function visible to this observer?
The problem is that on the first run through of the didTransition, the method is missing as that part of the script has not been executed.
Is this a problem? Actually no. The purpose of didTransition in this instance is to capture when a transition occurs as the supplied javascript from Google with capture to initial local of the page. All is needed is a check to see if 'ga' exists.
Add the recommended javascript to the index.html of your ember app from Google (https://developers.google.com/analytics/devguides/collection/analyticsjs/).
Modify your code to include a check to see if ga is undefined:
import Router from '../router';
Router.reopen({
notifyGoogleAnalytics: function() {
if (typeof ga != 'function') { return; }
return ga('send', 'pageview', {
'page': this.get('url'),
'title': this.get('url')
});
}.on('didTransition')
});
This is variation of what I have for an ember-cli based app. Let me know if it works.
After looking, exhaustively, for a way to plug Google Analytics into Ember, I built my own. For all those still struggling with this issue and not finding the Ember.js v1.0.0 answer helpful, here is how I got it to work on v4.2:
import Route from '#ember/routing/route';
import { action } from '#ember/object';
export default class ApplicationRoute extends Route {
#action
didTransition() {
gtag('set', 'page_path', window.location.pathname);
gtag('event', 'page_view');
return true;
}
}
Forgive my ignorance, as I am new to Ember, but the existing documentation makes it look like didTransition is no longer supported at the router level. That makes +99% of the solutions I found on the internet outdated.
Instead, I invoked didTransition at the route level. By extending Route as ApplicationRoute, I extended the main behavior of every Route. In this example, I execute the gtag event for triggering a page view after setting the page URL. The gtag code from Google simply goes in the index.html file in the head section.
Hopefully, this saves someone from hours of searching.

Configure Ember's back-end to communicate with a RESTful service

There seems to be a lot of discussion on SO (e.g. these questions: A, B, C, D) and other sites (e.g the Ember docs) about configuring Ember to allow cross-origin requests. That's all fine and well, but I'd rather have Ember's back-end do the work of communicating with a remote service (Ember's server-side components to make the request, rather than the user's browser). Is this documented? Can someone provide an example?
I thought I would find it easy to modify the HTTP server backing the ember serve command. Instead, I used the --proxy flag from Ember's CLI. It allows you to use remote services to provide data.
For this to work, let's assume a remote server foo.com:3000 provides JSON data at the path /resource. Configure a controller to GET the data like so:
import Ember from 'ember';
function getRemoteResource(store){
var dfd = Ember.$.Deferred();
Ember.$.ajax('/resource')
.done(function(data){
store.createRecord('model', data);
dfd.resolve();
})
.fail(function(err){
dfd.reject(new Error("An error occurred getting data.", err));
});
return dfd.promise();
}
export default Ember.Controller.extend({
actions: {
getResource:function(){
var dataStore = this.store;
return getRemoteResource(dataStore);
}
}
});
Use a template like this to invoke the controller's action:
<h2>Remote data example</h2>
<button class="my-button" {{action 'getResource' }}>
Get resource
</button>
Assuming your code is on host bar.com, start ember like this : ember serve --proxy http://foo.com:3000. Then, open your browser to the appropriate page that loads the template (somewhere like http://bar.com:4200/index) , click the button and see that remote data is loaded.

Ember CLI - Simple Auth - Custom Authenticator not automatically registering

I'm attempting to setup a custom authenticator with ember simple auth. I'm using Ember CLI and according to the Simple Auth ReadMe on GitHub it states. Note that when you're not using Ember CLI the authenticator will not be registered with the container automatically and you need to do that in an initializer.
It does not state where you need to put your authenticator (or authorizer for that matter) in your directory structure in order for it to be registered by Ember CLI automatically. After creating my file in app/authenticators/custom.js (as shown in the examples of the read me) I expected it to be registered with the container. Looking in Ember Inspector it's no where to be found.
Does anyone have any insight into this? Where are these files meant to be placed?
Please ask if any additional information is needed.
Ember: 1.7.0
Ember Data: 1.0.0-beta.10
Ember Simple Auth: 0.7.1
The latest version of Ember CLI should actually auto-register the authenticator - make sure you're using that (you probably aren't as you're still at Ember 1.7.0). That should solve it.
Make sure you have your initializer in /app/initializers/. Initializers in this directory are automatically set up by ember-cli.
// app/initializers/authentication.js
import CustomAuthenticator from '../authenticators/custom';
export default {
name: 'authentication',
before: 'simple-auth',
initialize: function(container, application) {
container.register('authenticator:custom', CustomAuthenticator);
}
};
I am getting the same issue and I have Ember 1.8.1
Error is:
Uncaught ReferenceError: CustomAuthenticator is not defined
in file app/authenticators/custom.js
I needed to add an initializer and change the code found in the docs to this below, and it works
import Base from 'simple-auth/authenticators/base';
var CustomAuthenticator = Base.extend({
restore: function(data) {
},
authenticate: function(options) {
},
invalidate: function(data) {
}
});
export default CustomAuthenticator;

How to handle invalid routes without slash in Ember.js

At the moment, I handle invalid routes in Ember.js like this:
this.route('invalid', { path: '*path' }
This works and applies to routes like:
https://www.appname.com/#/misspelled_name
However, when using Dropbox Datastores API, I am having some problems. After an authentication request, Dropbox redirects me to:
https://www.appname.com/#access_token=...
Is there a way to handle this route? Without the slash before the route name? In this case, the 'invalid' route is not applied and I receive an error 'The route access_token=... was not found'. How should I handle this response in Ember?
UPDATE
I don't think it is possible to handle this. The only working solution for me was to do authentication before Ember was even loaded. After successful authentication, I load my ember app:
window.dropboxClient = new Dropbox.Client({
key: 'some_key'
});
dropboxClient.authenticate({ interactive: true }, function(error) {
if (error) {
return console.log('Error during authentication');
}
});
yepnope([{
test : window.dropboxClient.isAuthenticated(),
yep : ['my-ember-app.js']
}])
I don't have direct experience with EmberJS, but one possibility might be to run client.authenticate({ interactive: false }); before the EmberJS script is even loaded.
Another alternative is to specify a different redirect URI (not the same page as the rest of your app) and not load EmberJS on that page. (That page would then presumably redirect back to the main app when it was done.) You could also forgo redirects altogether and use the pop-up auth driver instead.
Before the #/, you aren't actually inside of the ember app. As a result, none of the ember code will have any impact on this.
