-# Ember-api-requests
+# ember-api-requests
 
-This README outlines the details of collaborating on this Ember addon.
+Service for making custom requests to your backend API.
 
-## Installation
+This service extends [ember-ajax](https://github.com/ember-cli/ember-ajax) but uses [ember-data](https://github.com/ember-cli/ember-data) for building the URL.<br>
+This way you can make custom requests to your backend API the easy way.
 
-* `git clone` this repository
-* `npm install`
-* `bower install`
+For basic understanding please refer to the ember-ajax [documentation](https://github.com/ember-cli/ember-ajax) first.
 
-## Running
+## Usage
 
-* `ember server`
-* Visit your app at http://localhost:4200.
+To use the service, inject it into your route, component, service or other part of your app.
 
-## Running Tests
+Suppose your application adapter has `/api` as namespace and you have a model called `user` and you want to check if an username already exists:
 
-* `npm test` (Runs `ember try:testall` to test your addon against multiple Ember versions)
-* `ember test`
-* `ember test --server`
+```javascript
+import Ember from 'ember';
 
-## Building
+export default Ember.Service.extend({
+  api: Ember.inject.service(),
+  
+  usernameExists(username) {
+    return this.get('api').request('check-username', {
+      model: 'user',
+      data: {
+        username: username
+      }
+    });
+  }
+});
+```
 
-* `ember build`
+When calling above method with username `John`, a request will be made to `/api/users/check-username?username=John`.
 
-For more information on using ember-cli, visit [http://ember-cli.com/](http://ember-cli.com/).
+The request takes a 'action' path as first parameter and an options object as second parameter. 
+The service will create the URL from the given model name and the corresponding adapter. 
+The rest of the options are simply passed to the underlying jQuery ajax method, so you may pass any additional properties you would normally pass to a jQuery ajax request.
+
+#### HTTP methods
+
+All basic HTTP methods are supported:
+
+```javascript
+request('action', { model: 'user' }) // GET request to /users/action
+request('action', { model: user })   // GET request to /users/1/action
+post('action', { model: 'user' })    // POST request to /users/action
+put('action', { model: user })       // PUT request to /users/1/action (asuming user is a model with id 1)
+patch('action', { model: user })     // PATCH request to /users/1/action (asuming user is a model with id 1)
+del('action', { model: user })       // DELETE request to /users/1/action (asuming user is a model with id 1)
+```
+
+## API
+
+#### Request options
+
+All below options are optional.
+
+| option | type | description | 
+|:---|:---|:---|
+| model | Ember Data Model name or instance | Used for constructing the URL. When passing an instance, the `id` of the instance will be added to the generated URL. The service will use the underlying Ember Data Adapter of the model to construct the URL. If this option is omitted, the application adapter will be used to construct the URL. |
+| jsonData | Ojbect | Used for adding a `JSON` request body. Acts the same as defining a `data` object you would normally use when making a jQuery ajax request but additionally sets the content type of the request to `application/json;charset=UTF-8`. This option is only useful when doing a `post`, `put`, or `patch` request. |
+| params | Object | Used to add extra query parameters to the URL. |
+| requestType | String | Used by Ember Data to construct the URL. Defaults to `findRecord` when `model` is an instance and `findAll` when `model` is a model name. |
+
+#### Service methods
+
+| name | description | 
+|:---|:---|
+| buildURL(path, options) | The function used by the request methods mentioned above to create a request URL. |
