generating forms with a self-defined helper

im currently trying to implement a form with several buttons, and my solution for that was to make a full form for each of the 5 buttons. thats extremely repetitive, so i wanted to generate the forms with a helper function that i define myself, but i cant make it work.

my form method:

module ApplicationHelper   def raw_datum_new_helper(status)

    form_for(@raw_datum) do |f|       if @raw_datum.errors.any?       "<div id='error_explanation'>"         "<h2>#{pluralize(@raw_datum.errors.count, "error"})prohibited this raw_datum from being saved:</h2>"         "<ul>"         @raw_datum.errors.full_messages.each do |msg|           "<li>#{msg}</li>         #{end}         </ul>       </div>"     <% end %>

    "<div class='field'>"     #{f.hidden_field :timestamp, :value => Time.now.to_s[0,16]       f.hidden_field :status, :value => status}     </div><div class='actions'>"       f.submit :value => status     "</div>"     end

  end end

my errors when calling <%= raw_datum_new_helper("ins Bett gelegt") %>: /home/rynnon/workspace-ruby/sleepdata/app/helpers/application_helper.rb:15: syntax error, unexpected '}', expecting ')' ...aw_datum.errors.count, "error"})prohibited this raw_datum fr... ... ^ /home/rynnon/workspace-ruby/sleepdata/app/helpers/application_helper.rb:15: syntax error, unexpected ':', expecting '}' ...his raw_datum from being saved:</h2>" ... ^ /home/rynnon/workspace-ruby/sleepdata/app/helpers/application_helper.rb:18: unknown regexp option - l /home/rynnon/workspace-ruby/sleepdata/app/helpers/application_helper.rb:20: syntax error, unexpected '<'         </ul>          ^ /home/rynnon/workspace-ruby/sleepdata/app/helpers/application_helper.rb:21: unknown regexp options - dv /home/rynnon/workspace-ruby/sleepdata/app/helpers/application_helper.rb:24: syntax error, unexpected keyword_class, expecting keyword_do or '{' or '('     "<div class='field'>"                ^ /home/rynnon/workspace-ruby/sleepdata/app/helpers/application_helper.rb:30: syntax error, unexpected keyword_end, expecting '}'

Does anyone have an idea as to how to go about this?

Hi

Rails helper is normal ruby method so you can't write it like erb. There also a few syntax errors.

You'll be better off writing partial instead of helper.

Thank you! I just did that (iterated over an array with the variables that change), it was definitely less hassle than trying to make the function work.
