Send form params to controller without a model in Rails

Question

I have a form:

 <%= form_for(:user_email, :url => {:action => 'send_email'}) do |f| %>
    <%= f.text_field(:subject, class: 'form-control')%>
    <%= f.button "Submit", type: 'submit'%>
<% end %>

And a controller:

class UserEmailController < ApplicationController
   def send_email
      p params[:subject]
   end
end

This writes nil in the console instead of the text I put in my textfield.

Question: How can I access the content of my fields in the controller?

I should mention that the action itself is triggered, but the parameters are nil.

Answer 1

Use form_tag with your path. I have used /user_email/send_email . change it according to the route your have setup in routes.rb

 <%= form_tag('/user_email/send_email') do %>
    <%= text_field_tag(:subject, class: 'form-control')%>
    <%= submit_tag "Submit"%>
<% end %>

Answer 2

Try instead:

p params[:user_email][:subject]

And if that doesn't produce what you're looking for, try:

p params

... to inspect what's getting sent over the wire.
