Where to define custom data handling for a m2m field in django
Let's say for example I want the many to many 'tags' modelfield to be inputted as a space-separated list, were an unrecognized name be submitted it should also be created in the 'Tag' model. I'm aware this could be written either at:
- View level
- Form level
- FormField level
- ModelField level
I want to adhere to the DRY principle as tightly as possible.
For the time being I have defined it at ModelForm level but my setup is not very flexible. I would have to write new forms for every variation in each part of the website I place this formfield in.
