Add a CSS class to <%= f.submit %>
<%= f.submit 'name of button here', :class => 'submit_class_name_here' %>This should do. If you're getting an error, chances are that you're not supplying the name.
Alternatively, you can style the button without a class:
form#form_id_here input[type=submit]Try that, as well.
You can add a class declaration to the submit button of a form by doing the following:
<%= f.submit class: 'btn btn-default' %> <-- Note: there is no comma!
If you are altering a _form.html.erb partial of a scaffold and you want to keepthe dynamic change of the button name between controller actions, DO NOT specify a name 'name'.
Without specifying a name and depending on the action the form is rendered the button will get the .class = "btn btn-default" (Bootstrap class)(or whatever .class you specify) with the following names:
Update model_name
Create model_name
(where model_name the name of the scaffold's model)
Rails 4 and Bootstrap 3 "primary" button
<%= f.submit nil, :class => 'btn btn-primary' %>Yields something like:
