F.send in form?

Rails
1

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

<% Question.all.each do |question| %>

<%= f.send(:label, question.name), :class => ‘control-label’
%>

<%= f.send(question.data_type.to_sym, :question, :name) %>

<%= ’ allergic to shellfish?’ %>


    <% 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)

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

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’) %>

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?
