 <p>I resolved my issue. The problem was that I was using <a href="http://localhost:4200/" rel="nofollow">http://localhost:4200/</a> instead of <a href="http://127.0.0.1:4200/" rel="nofollow">http://127.0.0.1:4200/</a> and that's why I couldn't find django's cookie.</p> <p>As soon as I found django's cookie, I just add an attribute to the header of the adapter. </p> <p>My new adapter is shown below:</p> <p>Ember Adapter:</p> <pre><code>import DS from 'ember-data'; export default DS.RESTAdapter.extend({ host: '/api', contentType: 'application/json', dataType: 'json', headers: { "X-CSRF-Token": 'django token', username: 'XXXX', password: 'XXXX' }, buildURL: function(modelName, id, snapshot, requestType, query) { var url = this._super(modelName, id, snapshot, requestType, query); return url + "/"; } }); </code></pre>
