Add a CSS class to <%= f.submit %>
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 keep
the 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)
<%= 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.
