Rails loop through data in a form field -

i loop through data in database inside form. data put in labels , textboxes. how in rails? use .each block loop through inside form? reason have in database because client able add form field data himself.

---

for example here do:

<%= form_for :order |f| %>   @fields.each |field|     <%= f.label field.name %>     <%= f.text_field field.name %>   <% end %>   <%= f.submit %> <% end %> 

what best way accomplish this?

please don't answer railscast :)

thanks in advance

yes, work, though missed end script tag on line two:

<%= form_for :order |f| %>    <% @fields.each |field| %>          <%= f.label field.name %>        <%= f.text_field field.name %>    <% end %>    <%= f.submit %> <% end %> 

if need more complex label/text field pair - can use partial-template , use collection keyword:

<!-- in 'order.html.erb' --> <%= form_for :order |f| %>    <!-- note: each 'field' auto-populated collection/partial-name, need pass form in local -->    <%= render :partial => 'field', :collection => @fields, :locals => {:f => f} %>      <%= f.submit %> <% end %> 

and

<!-- in '_field.html.erb' --> <%= f.label field.name %> <%= f.text_field field.name %> <!-- , whatever else want do... -->
