Forum: Ruby on Rails f.send in form?

Can you do f.send in a form?  I have questions and the data type stored 
in
a db.

<% Question.all.each do |question| %>
          <div class="control-group">
            <%= f.send(:label, question.name), :class => 'control-label' 
%>
            <div class="controls">
              <%= f.send(question.data_type.to_sym, :question, :name) %> 
-
<%= ' allergic to shellfish?' %>
            </div>
          </div>

        <% end %>

Of course! Are you encountering any problems with that?

Is there something I need to do to the data_type to make it recognize
it as a method?

wrong number of arguments (3 for 0)

<div class="control-group">
48:             <%= f.label question.name.to_sym, :class => 
'control-label' %>
49:             <div class="controls">
50:               <%= question.data_type
"person[person_question_ids][]", question.id, nil %> - <%= ' allergic
to shellfish?' %>
51:             </div>
52:           </div>

You can access the object by using

f.object

then you can do

f.object.send

here 'f.object' return an instance of Question, but i think that 
whatever
you are trying to do you are doing it wrong, can you elaborate in what 
you
are trying to do?

Wait, what? You posted the correct code in your original post, but this
isn't that code. Line 50 here is saying, "call the data_type method on 
the
question object with these three parameters". The generated accessor
doesn't understand the parameters, and you get the error.

If you want to call a method whose name is selected at runtime, you 
*need*
to use send.

Been a while, I had the closing bracket in the wrong spot:
send needs all the params, it was erroring on , if i put the closing
bracket right after the data_type or name
<%= person_question.send(question.data_type.to_sym, question.name, 
:class
=> 'text_field') %>
