"Method Flowchart" for all CB(G)V documentation pages

[Ivan Ven Osdel]

First off, to whoever had the idea and put in the effort to add the "Method Flowchart" to some of the CBV and CBGV doc pages, thank you, thank you, thank you. So helpful.

Example "Method Flowchart": ​​https://docs.djangoproject.com/en/dev/ref/class-based-views/generic-display/#listview

So naturally I would love to see the feature on all of the CB(G)V pages, particularly those with a form as they are more complicated.

Why is this necessary?

1. To make the multiple branches of form view logic more explicit. What methods get called when there is a GET? What about a POST?

2. To gain all the advantages that the "Method Flow" chart has provided to the other views. For me it has been primarily helpful for understanding and figuring out how to avoid duplicate queries.

I'm a bit confused by your description (I've never heard of "Method flowchart"), but if you want to see whole ancestors tree with all methods (and code snippets!), have a look at ​http://ccbv.co.uk

The question whether this should be included in docs remains. Personally I use ​http://ccbv.co.uk a lot. Without this site the CBV would be very hard to customize (yes, I still can browse the source code, but it isn't definitely as convenient as ​http://ccbv.co.uk)

An example "Method Flowchart" is here: ​https://docs.djangoproject.com/en/dev/ref/class-based-views/generic-display/#listview.

I think this ticket may have to be addressed along with #19227 (Reorganize method flowchart for class based generic views to tree), as the method flowcharts would be more accurate and helpful in tree form as opposed to current lists.
