You have to specify <code>project_id</code>:

<pre><code>reverse('edit_project', kwargs={'project_id':4})
</code></pre>

blocks|key|226167|text|当我尝试使用反向生成激活链接并通过电子邮件发送时，这个问题让我非常头疼。所以我认为从tests.py来看也是一样的。正确的方法如下：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|226168|from+django.test+import+Client
from+django.core.urlresolvers+import+reverse

This problems gave me great headache when i tried to use reverse for generating activation link and send it via email of course. So i think from tests.py it will be same. 
The correct way to do this is following:

<pre><code>from django.test import Client
from django.core.urlresolvers import reverse

#app name - name of the app where the url is defined
client= Client()
response = client.get(reverse('app_name:edit_project', project_id=4)) 
</code></pre>

blocks|key|226178|text|函数resolve_url也更简单|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|226179|from+django.shortcuts+import+resolve_url

The function <code>resolve_url</code> is also more straightforward
<pre><code>from django.shortcuts import resolve_url

resolve_url('edit_project', project_id=4)
</code></pre>

blocks|key|226240|text|解决方案@miki725是绝对正确的。或者，如果您希望使用args属性而不是kwargs，则只需修改代码即可，如下所示：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|226241|project_id+=+4
reverse('edit_project',+args=(project_id,))|code-block|syntax|javascript|226242|这方面的一个例子可以在documentation中找到。这实际上做了同样的事情，但属性是作为参数传递的。请记住，传递的任何参数在被反转之前都需要赋值。只需使用正确的名称空间，在本例中为'edit_project'。|226243|entityMap|0|LINK|mutability|MUTABLE|url|https://docs.djangoproject.com/en/2.1/topics/http/urls/#examples^0|T|4|12|6|0|0|2K|E|B|D|0|0^^$0|@$1|2|3|4|5|6|7|U|8|@$9|V|A|W|B|C]|$9|X|A|Y|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|Z|8|@]|D|@]|E|$I|J]]|$1|K|3|L|5|6|7|10|8|@$9|11|A|12|B|C]]|D|@$9|13|A|14|1|15]]|E|$]]|$1|M|3|-4|5|6|7|16|8|@]|D|@]|E|$]]]|N|$O|$5|P|Q|R|E|$S|T]]]]

The solution @miki725 is absolutely correct. Alternatively, if you would like to use the <code>args</code> attribute as opposed to <code>kwargs</code>, then you can simply modify your code as follows:

<pre class="lang-py prettyprint-override"><code>project_id = 4
reverse('edit_project', args=(project_id,))
</code></pre>

An example of this can be found in the <a href="https://docs.djangoproject.com/en/2.1/topics/http/urls/#examples" rel="noreferrer">documentation</a>. This essentially does the same thing, but the attributes are passed as arguments. Remember that any arguments that are passed need to be assigned a value before being reversed. Just use the correct namespace, which in this case is <code>'edit_project'</code>.

Hi I have an infuriating problem.

I have a url pattern like this:

<pre><code># mproject/myapp.urls.py

url(r'^project/(?P&lt;project_id&gt;\d+)/$','user_profile.views.EditProject',name='edit_project'),
</code></pre>

it works fine in the browser but for testing, when I do this in the shell:

<pre><code>from django.test import Client
from django.core.urlresolvers import reverse

client= Client()
response = client.get(reverse('edit_project'), project_id=4)
</code></pre>

I get the dreaded:

<pre><code>NoReverseMatch: Reverse for 'edit_project' with arguments '()' and keyword arguments '{}' not found.
</code></pre>

What am I missing here?

Django Reverse with arguments '()' and keyword arguments '{}' not found
