javascript_for_update_column helper

[Dennis Bulgatz]

Hi Sergio,

I have a use case as follows:

A "User" has many "disciplines" through discipline_memberships and has many "skills" through skill_memberships.  A skill belongs to a discipline.

When editing a user, say we add a discipline_membership of "software developer".  Easy enough.  But I'd like to then automatically build all the skill_memberships for that user

corresponding to the skill belonging to the discipline. java, ruby, python, perl, c++ etc.

Not sure if javascript_for_update_column helper is the right approach to trigger building new skill_membership associations when a discipline_membership is added?  If so, any examples of how this would work?  Or is there a higher-level helper that could build associations"

Thanks

Dennis

You can add the associated records in the after_render_field method in the controller, and set them to an instance variable. Then you can create render_field.js.erb, with <%= render :super %> and add code to render the rows for the new associated records. However you will have to add some JS to find the parent element to add these rows, as they will be in a different subform if I understand correctly.
