如何将视图从一个django views.py导入到另一个

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? Eg could conflicts arise? etc.

Answer 1

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()),
]

Answer 2

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(...)
