Test views, templates, and URLs together with the Django test client

Django Test Client

The Self.client.get (URL) test client is a property name for the TestCase class in Django.

Now you can create a list in your Web site.

So, now it's time to test the new list in unit test.

Added a view function to the new manifest and mapped it to the URL ' ^/lists/new$ '. Where do you use it? Specify this URL in the action of the new List form on the home page.

The current implementation is:

1. Get home page, open the homepage. You can see the list of input backlog items.

2. Post home, you can create a list. and display the backlog in the list. Opens the URL of the new list

3. Post List page. To see new to-dos

The current problems are:

1. There is currently only one list

2. A list shows all the to-dos and cannot be quarantined.

Solve the problem:

To handle the isolation problem, you must modify the model and create a new List class. And let the class and item relate. Need to use model knowledge.

List is self-contained: use a regular in the URL, add a capturing group (. +), and the captured text is passed into the view as a parameter input

Item each item should exist in a list.

Capturing a group (. +) can not only capture/(. +)/can also capture/((. +)/new_item ..... So write the URL, to avoid the use of regular, matching is too wide.

Response = Self.client.get ('/lists/%id/'% (correct_list.id,))

Self.assertequal (response.context[' list '],correct_list) # Response.context represents the context to pass in the render function. The Django client has the context attached to the response object for easy testing.

In Template:

{% for new_item_text in list.item_set.all%} #. Item_set is called a reverse query. is a very useful ORM feature provided by Django. You can query related records for an object in other tables.

So in the from of the template. You can pass in a modle instance. Then find the relevant other object instances based on this instance:

<form method= "POST" action= '/lists/{{list. id}}/new ' >
<input name= "Item_text" id= "Id_new_item" placeholder= "Enter a to-do item"/>
{% Csrf_token%}
</form>
<table id= "Id_list_table" >
{% for new_item_text in list.item_set.all %}
<tr><td>{{Forloop.counter}}: {{new_item_text.text}}</td></tr>
{% ENDFOR%}
</table>
