Rails: form generation based on conditions

Question

I've got a form to build a Document. That form needs adjusting depending on what type of Document a user has chosen. At this point I've got a deferring kind of method in new.html.erb that goes like this:

<%= render 'form_'+@template.label.downcase.parameterize.underscore %>

Which works fine but it's kinda difficult to manage though because when new types of documents are added I need to create actual HTML files and upload them.

Is there a better way to manage this kind of form generation? A view with hundreds of if statements in it feels cumbersome too.

Answer 1

You can push it to document_helper or decorator like :

module DocumentHelper
  def form_render
    return 'form_#{type}'
  end
end
