Ruby on Rails - adding CSS to text_field - css

Question

I created a form in Rails and when I add a CSS class to a text_field the form will not submit.
I am still new to rails so any help would be much appreciated.
This is my 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'} do |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 is that my form will only submit without the :class => "form-control" in it. I must have brackets around each of the form field variables.
This is my routes.rb file:
Rails.application.routes.draw do
root "home#index"
match ':controller(/:action(/:id))', :via => [:get, :post]
end
This is my controller:
class HomeController < ApplicationController
def home
render("home/index")
end
def new
#fc = FeedbackCustomer.new
end
def create
# Instantiate a 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 help would be much appreciated. Thanks!

Answer 1

If you're using Ruby 1.9+ This should work:
<%= f.text_field :last_name, class: 'form-control' %>
If you're using a version that's older than 1.9 then this should work:
<%= f.text_field :last_name, :class => 'form-control' %>
For more information on this you can use the ActionView::Helpers::FormTagHelper API Documentation
The Form Helpers Rails Guide might be helpful to you as well.

For the most recent version of Ruby you can now also do:
<%= f.text_field :last_name, class: 'form-control' %>
