Ruby on Rails - adding CSS to text_field -

i created form in rails , when add css class text_field form not submit.

i still new rails appreciated.

this form:

<% @page_title = "contact" %>     <hr>     <div class="col-lg-12">                 <h1 class="page-header">                     bk legal courier corp <br />call bk @ <span style="color:#47b224">613-286-8265</span>                 </h1>             </div>  <hr> <div class="container">   <h2>contact us</h2>    <%= form_for :fc, :url => {:action => 'create'} |f| %>     <div class="form-group">       <%= f.label :first_name %>       <%= f.text_field (:first_name, :class => 'form-control')%>     </div>     <div class="form-group">       <%= f.label :last_name %>      <%= f.text_field (:last_name, :class => 'form-control') %>     </div>      <div class="form-group">       <%= f.label :email %>       <%= f.text_field (:email, :class => 'form-control') %>     </div>      <div class="form-group">   <%= f.label :comment %>  <%= f.text_area (:comment, :class => 'form-control') %> </div> <div class="form-group">   <%= f.label :referral %>         <%= f.select (:referral, [['friends', 1], ['news', 2], ['online', 3], ['other', 4]], :class => 'form-control')%> </div>  <%= submit_tag ("submit") %>   </form> </div>  <% end %> </body>  </html> 

the problem form submit without :class => "form-control" in it. must have brackets around each of form field variables.

this routes.rb file:

    rails.application.routes.draw   root "home#index"     match ':controller(/:action(/:id))', :via => [:get, :post]      end 

this controller:

    class homecontroller < applicationcontroller      def home         render("home/index")      end       def new @fc = feedbackcustomer.new   end   def create      # instantiate new object using form parameters     @fc = feedbackcustomer.new(feedbackcustomer_params) if @fc.save     redirect_to(:action => "home") end   end    def application    end  private  def feedbackcustomer_params params.require(:fc).permit(:first_name, :last_name,      :email, :comment, :referral)     end end 

any appreciated. thanks!

if you're using ruby 1.9+ should work:

<%= f.text_field :last_name, class: 'form-control' %> 

if you're using version that's older 1.9 should work:

<%= f.text_field :last_name, :class => 'form-control' %> 

for more information on can use actionview::helpers::formtaghelper api documentation

the form helpers rails guide might helpful well.
