Autocomplete in Django

[Mreno sert]

I have a small app in which I have form for taking 5 inputs as City1, City2,City3,City4 and City5 as the fields. I have written a code for auto completing it but A user can not enter the new fields. Only existing values can be used. How can I make it to accept a new field if not present in the database

[Andréas Kühne]

That really depends on how you want it to work?

I would probably add an item on the dropdown that shows the current items in the database, with "Add city". If the user presses that you can have an AJAX call that adds the item to the database.

Andréas

Hi.

Besides the way Andréas described, there exist autocomplete fields that can accept arbitrary input you can send to backend without having to create special add phase.

Adding such functionality of course requires a custom field that can add nonexisting values to database.

In particular, you need to override the ModelChoiceField that a
ModelForm creates automatically and replace it with a field that is
not based on ChoiceField at all or skips it's validation method (like
https://github.com/yourlabs/django-autocomplete-light/blob/master/src/dal_select2/fields.py#L34).

Thanks for the help...but I do not know ajax. Is there anything simpler like I heard about "create-field" option. Tried it , but not getting it done correctly.

Then you need to learn Ajax.
You can't do dynamic forms like this and not use Ajax.

I linked django-autocomplete-light for a reason: if you follow the
docs and use it, you can build things you need without knowing Ajax.
However, if it doesn't work or is creating problems because of
incorrect input, it is vital you know the foundation of Ajax to
troubleshoot.
