Question

I have several objects in the database. Url to edit an object using the generic view looks like site.com/cases/edit/123/ where 123 is an id of the particular object. Consider the cases/url.py contents:

url(r'edit/(?P<object_id>\d{1,5})/$', update_object, { ... 'post_save_redirect': ???}, name = 'cases_edit'), 

where update_object is a generic view. How to construct the post_save_redirect to point to site.com/cases/edit/123/. My problem is, that I don’t know how to pass the id of the object to redirect function. I tried something like:

'post_save_redirect': 'edit/(?P<object_id>\d{1,5})/' 'post_save_redirect': 'edit/' + str(object_id) + '/' 

but obviously none of these work. reverse function was suggested, but how to pass the particular id?

'post_save_redirect': reverse('cases_edit', kwargs = {'object_id': ???}) 

{% url %} in the temple also requires passing the id of the particular object. The id can be passed via extra_context:

extra_context = {'object_id': ???} 

In all the cases the problem is to get object_id from the url.

In short what you need to do is wrap the update_object function.

def update_object_wrapper(request, object_id, *args, **kwargs):     redirect_to = reverse('your object edit url name', object_id)     return update_object(request, object_id, post_save_redirect=redirect_to, *args, **kwargs)
