Django：django.test TestCase self.assertTemplateUsed

Question

作業中Hello Web Appです。

TestCaseでお手伝いしてください：test_edit_thing。

ここでエラーの詳細があります：「/もの/ジャンゴ・ブック/編集/」の場合

エラー：

# AssertionError: No templates used to render the response 
response = self.client.get('/things/django-book/edit/') 
self.assertTemplateUsed(response, 'things/edit_thing.html') 

エラー「/もの/ジャンゴ・ブック/の場合「：

# AssertionError: Template 'things/edit_thing.html' was not a template used to render the response. Actual template(s) used: things/thing_detail.html, base.html 
response = self.client.get('/things/django-book/') 
self.assertTemplateUsed(response, 'things/edit_thing.html')

あなたが持っていた問題は、ユーザーが認証されなかったことであり、ユーザが事のユーザーと同じでない場合はHttp404を上げる

それあなたのedit_thingビュー

if thing.user != request.user: 
    raise Http404 

あなたは認証が必要でした。そしてそれはloginの
