Re: Extend FAQ with "How do I get Django and my JS framework to work together?"

[Dmitriy Sintsov]

Speaking of Rails AJAX forms. It's quite trivial to submit Django ModelForm 
in Javascript AJAX request. It's a bit harder to have the customizable 
success action and to display the field validation errors via AJAX response.

I implemented AJAX viewmodels for that:

https://django-jinja-knockout.readthedocs.io/en/latest/viewmodels.html#ajax-actions

However it's the mixed traditional forms + AJAX approach, not the pure SPA. 
In pure SPA Django becomes the "data supplier" where most of the templates, 
forms, presentation is performed by Javascript framework.

So, the question is, whether the features of Django such as inline formsets 
and custom widgets are required, or should Django become the data store 
only.

The problem with ModelForm is translating validation to something
front-end, like jquery Validator.   Here, DRF does better, because swagger
spec includes something like jsonschema (neither are a standard as I used
to know them, in the WSDL/SOAP days), and so you can use jsonschema
validation to validate on the front-end.   I think what is needed is some
way to map validate-only to the back-end, and do a sort of 2-phase commit -
validate before the user presses OK, and then save (PATCH) when the user
presses save/apply/OK.
