Question

i have a rails form ive made in which the form fields are extracted from the database. i did it like this because for different products, there are different form fields. i could have made one big order form to do it, and if the product field didnt apply to the product it would be left blank, but it seemed like making the fields being called from a database made more sense because there are 30-40 fields per order. anyways the error in which im running into is when im extracting the row field_type, it prints out the literal value instead of putting it in rails. heres what it looks like:

  <% @form_field.each do |field| %>
    <p>
      <%= "f.#{field.field_type}" %> #this prints out f.text_field
    </p>
  <% end %>

Instead of printing out f.text_field, i would like it to actually make a text field. I tried using raw but no look seeing as thats for html. is there a way to do this in rails?

You’d need to build up the string and send it to f, like f.send(field.field_type) (untested) along with any arguments needed for that particular form field type.
