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:

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

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

en:
  helpers:
    submit:
      post:
        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.
