How to transfer edit method of an ID to a button/links in Django?

问题

This is the code in my ulrs.py

url(r'^viewguides/detail/(?P<id>\d+)/edit/$', views.post_update, name='update'),

Now I want to make it look like this:

<a href="/detail/(?P<id>\d+)/edit" class="btn btn-default btn-lg" style="background-color: transparent;"><font color="Orange"> EDIT </font></a><hr>

So that I can edit the certain ID that I want to. But it gives me an error. How do you do it? or is there any other way? I'm new to Django.

回答1:

I just asked my colleagues who have some experience in Django. The answer is very simple.

you just need to create this function in "models.py" :

def get_absolute_url(self):
    return "/viewguides/detail/%s/" %(self.id)

and then you can call it in the html by:

<a href="{{obj.get_absolute_url}}edit" class="btn">EDIT</a>

Every time you click the btn EDIT, it will take you to the following edit page with the given id (id that contains the forms/models of the user).

You must use the url tag in your template, something like this:

<a href="{% url update guide.id %}">EDIT</a>

Where "update" is the name found in urls.py and "guide" the instance you want to update.
