Babban matsalar ita ce keɓance maɓallin ƙirar ƙirar django admin a cikin filin na iya haifar da halayen da ba a zata ba.
I have a model with a foreign key to another model. In the admin view, I want to customise the edit button for this field.
In my admin.py:
<code>class MyModelAdmin(admin.ModelAdmin):
def edit_button(self, obj):
return '<a href="/myapp/mymodel/%s">edit</a>' % obj.id
edit_button.allow_tags = True
edit_button.short_description = 'Edit'
list_display = ('name', 'edit_button')
</code>
This works fine and gives me an "edit" link in the column for each row of my list view, but it links to /myapp/mymodel/1 instead of /admin/myapp/mymodel1/. How can I make it link to the admin page?
A:
You can use <code>reverse()</code>: https://docs.djangoproject.com/en/dev/_modules/django/core/urlresolvers/#reverse (or <code>urlresolvers</code>, which is what reverse is imported as) It will automatically generate urls based on your urls file and any named url patterns you have defined in there (like <code>admin:index</code>) So you could do something like this: (I'm assuming your app name is "foo") If not, just change it accordingly in the code below... Also note that I've changed your function name from <code>edit_button()</code> to <code>get_edit_link()</code>. This is because Django uses methods starting with get as accessors for fields in a model class... So if you don't change it, Django will try and call that method on your model class instead of on your ModelAdmin class... Which won't work because there's no such method defined on your model class... Anyway, here's how you could do it: (Note that I've also added an import statement at the top) Also note that I've changed your function name from <code>edit_button()</code> to <code>get_edit_link()</code>.
