If I wish to create a set of checkboxs based on the rows of a table in my database would I have to loop through each row of the database using a for loop? or can I just use the check box method once and pass it an array of values?
I'm not sure if there is an existing helper. I generally use a loop:
<% @categories.each do |category| %>
<%= category.name %><br/>
<% end %>
The above code demonstrates the assigning of categories to products in a has and belongs to many relationship.
This could easily be extracted into a helper for use throughout your application.
There are a few plugins related to checkboxes and other form helper - you could either use those or take a look at the source for inspiration for your own code: http://www.agilewebdevelopment.com/plugins/search?search=checkbox
Hope that helps,
