submit(value=nil, options={}) public

Add the submit button for the given form. When no value is given, it checks if the object is a new resource or not to create the proper label:

<%= form_for @post do |f| %>
  <%= f.submit %>
<% end %>

In the example above, if @post is a new record, it will use “Create Post” as submit button label, otherwise, it uses “Update Post”.

Those labels can be customized using I18n, under the helpers.submit key and accept the %{model} as translation interpolation:

      create: "Create a %{model}"
      update: "Confirm changes to %{model}"

It also searches for a key specific for the given object:

        create: "Add %{model}"

About the options argument

The options are not documented, but of course you can use the same options than submit_tag.

Note that all non-documented options are simply passed to the input tag. Amongst other things, this allows you to change the default name attribute (commit):

form.submit 'Cancel', :name => 'cancel'

That’s very handy in forms with multiple submit buttons, this way the controller can easily check in the params which action was submitted.

Access just the label text

One of the handiest features of `f.submit` is the auto-generated label text.

Some styling frameworks don’t lend themselves to using `f.submit` without lots of tweaking.

If you’re not using `f.submit` but still want to access the label text, note that there is a private method:


One example (in Haml, using MaterializeCss):

    %button{ type: 'submit', name: 'commit', data: { disable: { with: 'Submitting...' } }, class: 'waves-effect waves-light btn maroon' }
      = f.send(:submit_default_value)
