How to import views from one django views.py to another

Question

I am learning Django. I have 2 functions in my app, one for cats, and another for dogs (as an example). I have the following folder structure:

/myproject/templates <-- dogs.html, cats.html
/myproject/dogs/ <-- views.py, models.py etc
/myproject/cats/ <-- views.py, models.py etc

Now both cats and dogs have shared views, etc, but currently I am just repeating these in each views.py file. Is there a way to "import" views and definitions from one view to another quickly?

This would save me cut and pasting a lot of the work.

What are the dangers of this? E.g. could conflicts arise? etc.

Your question is clear but the problem youre trying fo solve is not. If you provide more exact details of your project, we can provide a more useful response — skzryzg, Oct 11 '14 at 12:11

sure, you can use inheritance and you should use CBV in this case

import Animal

class Dog(Animal):
    ....
    pass

class Cat(Animal):
    ....
    pass

You must change your urls.py as well

from django.conf.urls import url
from dogs.views import Dog
from cats.views import Cat

urlpatterns = [
    url(r'^dog/', Dog.as_view()),
    url(r'^dog/', Cat.as_view()),
]

Thanks, what if I want a view to inherit all properties of multiple other views? – alias51 Oct 11 '14 at 11:01
you can't inherit another view with FBV (Function Based Views) in Django – Sasa Oct 11 '14 at 11:05
here is the good explanation why to use CBV http://stackoverflow.com/questions/14788181/class-based-views-vs-function-based-views – Sasa Oct 11 '14 at 11:06

The simplest thing is to have the URLs for cats and dogs point to the same views:

urlpatterns = patterns(
    'catsanddogs.views',
    url(r'^(?P<kind>dog|cat)/(?P<id>\d+)$', 'details'),
)

And then in catsanddogs.views:

def details(request, kind, id):
    if kind == "dog":
        ... whatever is specific to dogs ...
    elif kind == "cat":
        ... whatever is specific to cats ...
    else:
        raise ValueError("...")

    ... whatever applies to both ...
    return HttpResponse(...)
