I have just added support for :add_new with singular associations in :chosen,
but I couldn't test it. I hope it works as in other form_ui, please test it
and report any issue.

Regards,
Sergio

Hi Gloufy

I have tested chosen with add_new, in a belongs_to association, and I had to fixed it. It's in master branch, which I expect to release as 4.2.0 soon.

However, using add_new with has_many association is not supported, either using :select or :chosen.

The belongs_to or has_one associations support getting an ID to associate with an existing record, or a hash with fields from subform, saving a new record. So add_new just had to change between one UI or another, and the existing code saving the params would work.

However, a has_many association expects an array of IDs, or an array of hashes. I don't think the code that parses the params to save the form would work with a mixed arrays of IDs and hashes. The easier way to support this would be adding a link to open a new tab or jQuery dialog, with the form to create a record, and then use JS to add the new record into the available choices (checkbox or option in a select). But there is no support for that yet.

Sergio

I just remembered that AS has a popup mode for add_new, which worked exactly as I described, so I have added support for add_new with popup mode in multiple associations.

You can use form_ui = :chosen, {add_new: {mode: :popup}}, or you can use the short syntax, form_ui = :chosen, {add_new: true}, which will default to popup mode for multiple associations.

It's supported for :select and :record_select on multiple associations too, for any of the :select versions on collection associations (checkboxes, draggable lists or select tag with multiple attribute).

Sergio
