Hi people
I have a problem. Maybe this is something easy, but I can’t figured
out with my knowledge.
To explain my problem, let’s supposse I have a model call User, the DB
table for users
Users
-id
-username
-age
and a model Account, where a user has many accounts and an account
belongs to user. The DB table for accounts
Account
-id
-user_id
-account_name
in my form for accounts I have a collection_select, to select a user.
Then I want to have a text field for the age of the user. The idea is
that when I choose a user in the collection_select, the
text_field :age get filled automatically with the age of the user
previously selected.
Which is the best approach to figured this out??
I hope you can help me, thanks
