Hello all. Am I going totally nuts here and just want to check (Natch!) something. A normal check_box has two value posssibilities. One for checked and one for unchecked, the value gets submitted with a form. The check_box_tag on the other hand, has a checked_value (Called just ''value'') and for the unchecked value...nothing, zip, nada. This means that if you submit a form with

#check_box and #check_box_tag are going to be the end of me. Why is this always checked? <% checked = @reservation.selected ? ''checked'' : nil %> <td><%= check_box_tag("reservation[" + @reservation.id.to_s + "][selected]", ''checked'', :checked => checked) %></td>

Hi, I have the following code working in a rails 3 view, but it is unfortunately not pure rails code! <% @filter1 = "tr.show1,tr.show2" %> <% @filter2 = "tr.show1" %> <% @filter3 = "tr.show2" %> <form> <p> <input type="checkbox" value=<%=@filter1%> onclick="$ (this).is('':checked'')

Hi, I have this in my form <%= check_box_tag(@accept, value = "1", checked = false) %> Which puts a nice checkbox on my form but when I try to retrieve the value that is returned, which I expect to find in @accept, there is nothing. How do I check the returned value? Thanks, Paul Thompson

Disclaimer: Ruby newbie at work Thought I was going so well. Wanted to produce a select box from an array constant, with the indices returned as values , and the array values used as the descriptions. Checked out Ruby RDoc and saw there was an each_with_index method and came up with: <%= select (''type'', ''typecategory'', Typecategory.each_with_index

Alright, I got this table with lots of entries for menus. There''s several menus (with their own model since each menu got some special information). Now, I want to be able to specify the order of the menu entries inside the menu. acts_as_list seems to not quite do the trick since it does ordering "globally" on the whole model and acts_as_nested_set seems like overkill since

Hi, I have a few simple rails questions: Does the check_box_tag map to an int or to a boolean field within the database?

Okay so I have a typical search page where a keyword is entered and results are retrieved that match the keyword. What I want to do now is have checkboxes to search for results in specific areas (my site is a big events calendar with "streams" and "audiences") I want to use the checkboxes to look for results in ''streams'', ''audiences'', or

Hi, The default way we handle an array of checkboxes is like this: <% items.each do |item| %> <%= check_box_tag ''item[]'', "#{item.id}" %> <% end -%> this returns an array item[] that holds the ids of all the items. Now the real issue: 1. The above loop will same ids to ''n'' items 2. All ids will be ''item[]''

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? Regards, Paul

Is it possible to set up a list of checkboxes so that the form parameters are given in an array (eg {"delete_list" => [3,6,7]}) ? At the moment I''m using <%= check_box_tag "delete_list[#{post.id}]" %> ...which gives parameters looking like {"delete_list" => {"3" => "1", "6" => "1",

I''ve spent hours researching the subject and have tried many test sequences in IRB, and rails console but I''m just having trouble making headway into what is probably a very easy subject. I understand arrays with at least 4 other languages but with Ruby I haven''t found a mental connection with how I can assign variables to arrays.. Take for example: def

I have a model object that acts as a list. The position of each object is determined by two factors: number of votes ascending and age of object descending. When a user adds or deletes a vote I need to quickly update the associated model object''s position.
