Hi All, I''ve tried to do my searches, but can''t find reference to this anywhere - My question is about ActiveRecord inserts and IDs. I have a join table that both the models of the source tables join with "has_and_belongs_to_many".

Hello all, I''ve been working with Ruby on Rails for a few weeks now. It''s difficult for me because I don''t have much experience with Ruby, Rails, MySQL, or any other web-languages.

All, I''m starting to see view state information creeping into my model class. For example, I have text fields in my view that need to be set a certain way depending on whether or not a checkbox is checked.

Hi, I would like to put a checkbox on a form where the input field is a variable rather than a field in a model. The normal way (with a model) would be: <%= check_box(''client'', ''accept'', {}, "1", "0") %> But since accept is a variable @accept and model client will not be there, how do I make a check box work?

I have two questions: 1. I have a checkbox on a form and after submit I need to check the status of the checkbox. Any idea how to see what the checkbox is set to? I am assuming this must be done in the controller or model but cannot figure it out. 2. On load I am checking for a cookie and need to determine if the checkbox should be checked or unchecked.
