Ruby on Rails Forms: how to create a CheckBox Table (or List)
What's the best way to create a related set of checkboxes in Ruby on Rails? In the ToscaWidgets library used by Turbogears you can do the following:
twf.CheckBoxTable('arbitrary_numbers',
num_cols=5,
options=['1','2','3','4','5','6','7','8','9','10']),
This generates 10 labeled checkboxes i开发者_StackOverflown two rows of 5 checkboxes. I'm trying to duplicate this in Rails without just creating 10 separate checkbox controls. No big deal, just hoping for a clean way to do this.
Something like this:
<% 10.times do |i| %>
<%= label_tag i %>:
<%= check_box_tag "alternate_numbers[#{i}]" %> <br />
<% end %>
will produce 10 checkboxes and if you will put it into form and submit it, you will have access to it in params[:alternate_numbers][index]
where number is your number. You can put it into helper and call many times. You can also add some parameters to helper to customize output.
