Hi, I’m having trouble to create an application with dynamic fields. Could you guys help me out? I’m not gonna write everything again, here’s the stack overflow post and a 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 have a contact_id column and a custom_field_id column (to indicate which contact & 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.
