在 Django 中手动调用基于类的通用视图

Question

I'm currently trying to call a class based Generic view from within another class based generic view and cant seem to do it correctly.

Ways I've tried:

result = CategoryTypes.as_view()  # The same way you put it in the urlconf
print result

Prints: <function CategoryTypes at 0x92bd924>

CategoryTypes.as_view()(self.request)
# &
CategoryTypes().dispatch(self.request)

Tracebacks:

ContentNotRenderedError at /crm/categories/company/ The response content must be rendered before it can be accessed.

result = CategoryTypes().__init__()
print result

Prints: None

How do I call this from another view? I've seriously tried every method in the class and way of calling it I can think of.

Answer 1

The first way -- CategoryTypes.as_view()(self.request) -- is right. The problem is that if your view returns a TemplateResponse , its render method isn't called automatically.

So if you need to access the content of the response, call render() on it first.

Answer 2

Or you can directly access just content via result.rendered_content . Before making this be sure you will set session into your request before passing into a view:

self.request.session = {}
CategoryTypes.as_view()(self.request)
