How to fetch index data in Angular using rails server - ruby-on-rails

Question

I am starting with Angularjs + rails backend and trying to fetch users data from the server - equivalent to to controller/index action in rails.
I have followed several tutorials and found this code as the most clear one....
questions
1. How to properly link angular module into views ?
2. How to fetch data using typeahead and sample data in this post.
here is plunker version of the code
Code is as follows:
views
<div ng-app='users'>
<div class='container-fluid' ng-controller="UsersIndexCtrl">
<pre>Model: {{result | json}}</pre>
<input type="text" ng-model="result" typeahead="suggestion for suggestion in users($viewValue)">
</div>
</div>
controller
<script>
// ['ui.bootstrap', 'ngResource'])
var app = angular.module('users', ['ui.bootstrap', 'ngResource']);
// factory - resources users
// equivalent to rails users/index
app.factory('Users', function($resource) {
return $resource('/users.json', {}, {
index: { method: 'GET', isArray: true}
});
});
// factory - user resource
// equivalent to users show, update
app.factory('User', function($resource) {
return $resource('/users/:user_id.json', {}, {
show: { method: 'GET' },
update: { method: 'PUT' }
});
});
// controller - users/ index
// equivalent to rails controller rails/index
var UsersIndexCtrl = function($scope, users) {
$scope.users = users;
};
</script>
and I am stack here, as I am getting this error:
Error: Unknown provider: usersProvider <- users
The goal of this code is to use typehead and provide data to the user.
My '/users.json' url is as follows:
[{"full_name":"Lia Cartwright","id":1,"image_url":"no-icon.jpg"},{"full_name":"Hilton Turner","id":2,"image_url":"no-icon.jpg"},{"full_name":"Aubrey Barrows","id":3,"image_url":"no-icon.jpg"},{"full_name":"Donnie Kris","id":4,"image_url":"no-icon.jpg"},{"full_name":"Eryn Rath","id":5,"image_url":"no-icon.jpg"},{"full_name":"Caden Fay","id":6,"image_url":"no-icon.jpg"},{"full_name":"Arlie Tromp","id":7,"image_url":"no-icon.jpg"},{"full_name":"Rico Klein","id":8,"image_url":"no-icon.jpg"},{"full_name":"Gudrun Dare","id":9,"image_url":"no-icon.jpg"},{"full_name":"Nathan Langworth","id":10,"image_url":"no-icon.jpg"},{"full_name":"Deanna Stroman","id":11,"image_url":"no-icon.jpg"},{"full_name":"Shania Stroman","id":12,"image_url":"no-icon.jpg"},{"full_name":"Lupe Harvey","id":13,"image_url":"no-icon.jpg"},{"full_name":"Constance Armstrong","id":14,"image_url":"no-icon.jpg"},{"full_name":"Reagan Tremblay","id":15,"image_url":"no-icon.jpg"},{"full_name":"Murray Sipes","id":16,"image_url":"no-icon.jpg"},{"full_name":"Dandre Klocko","id":17,"image_url":"no-icon.jpg"},{"full_name":"Haylee Monahan","id":18,"image_url":"no-icon.jpg"},{"full_name":"Florence Harber","id":19,"image_url":"no-icon.jpg"},{"full_name":"Norberto Hoppe","id":20,"image_url":"no-icon.jpg"}]

Answer 1

You must inject Users not users, it's case sensitive.
Side notes:
No need to create two models, replace:
app.factory('Users', function($resource) {
return $resource('/users.json', {}, {
index: { method: 'GET', isArray: true}
});
});
app.factory('User', function($resource) {
return $resource('/users/:user_id.json', {}, {
show: { method: 'GET' },
update: { method: 'PUT' }
});
});
with:
app.factory('User', function($resource) {
return $resource("users/:id", { id: '#id' }, {
index: { method: 'GET', isArray: true, responseType: 'json' },
show: { method: 'GET', responseType: 'json' },
update: { method: 'PUT', responseType: 'json' }
});
})
Other thing, in your controller, do:
var UsersIndexCtrl = function($scope, User) {
$scope.users = User.index();
};
Last thing, consider using: Angular Rails resource
