Added Django extensions
Added the NestedModelForm class that we will use instead of just directly extending ModelForm. This accepts a child_form and child_actions_form attribute. When these are passed in, we call setup_nested_form which does alot of stuff (read the doc string). We also added some JS method to generate what the JS call will look like. Additionally, there's an example of a ActionsForm that can be supplied.
Added the form_templates management command that basically looks for all model forms and prints out template for it. Right now there's a CSRF warning that gets printed out in the markup that we need to remove. Additionally, we need to change it so that it accepts only one keyword as an argument.
Added our nested form tag @ the top.
Ok, adding the first iteration of our nested_crispy tag. It uses a CompositeNode and Django's node list to print out the list of nodes. All we did essentially was to create a list of Crispy Node tags that we stuck in a node list and rendererde the node list.
Changed the view to always render an instance, just so we could confirm that we're actually picking up the child data in the instance.
