Application with dynamically/custom fields

Hi, I’m having trouble to create an application with dynamic fields.
you guys help me out?
I’m not gonna write everything again, here’s the stack overflow post and
gist with what I got working and what’s not.

The links have the same content:

Thank you!

You’ll want to read up on fields_for, which will help you build the
required HTML inputs. I’d also recommend the Railscast on this
topic: #196 Nested Model Form (revised) - RailsCasts

Some other general notes on your Gist:

  • has_many associations should be plural. Things will usually work with
    them named otherwise, but you may encounter odd behavior.

  • the data model doesn’t seem quite right - custom_field_infos should
    a contact_id column and a custom_field_id column (to indicate which
    & field this record has data for). It shouldn’t need a user_id column
    unless there’s something else going on that’s not mentioned in the Gist.
