It’s super common to want to edit records along with their has_many associations on a single page.
This Rails gem helps creating forms for models with nested has_many associations and relies on jQuery to dynamically add and remove nested form fields without a page reload.
- Works for arbitrarily deeply nested associations (tested up to 4 levels).
- Works with form builders like simple_form.
- Requires at least Ruby 1.9 and the Rails asset pipeline.
To install, add nested_form_fields to your application’s Gemfile:
Run bundle intall to install the gem:
In application.js file add:
assuming that you have a User model with nested videos:
1 2 3 4
Use the nested_fields_for helper inside your user form to add the video fields:
1 2 3
Links to add and remove fields can be added using the add_nested_fields_link and remove_nested_fields_link helpers:
1 2 3 4 5
Note that remove_nested_fields_link needs to be called within the nested_fields_for call and add_nested_fields_link outside of it via the parent builder.
So far so good, That’s it!!! See ya!!! :)
