django: DetailView: self.object raises an error when called from the method post, but it does work when called from the method get_context_data

Question

I created a class that inherits from DetailView, and I overrided the methods get_context_data and post. What it seems weird as mentioned in the title, is that I can call self.object from get_context_data but I can't from post so I had to use self.get_object() instead. But I would like to understand why? is self.object removed by get_context_data? so that any method called after it cannot use it or something like that?

Thanks in advance

Answer 1

post method doesn't exist by default in DetailView, you actually creating it not overriding, so therefore you need to fetch the object by yourself, the reason it'a available in get_context_data is that it's already fetched inside get method and saved in object property.
