instance method
button
Ruby on Rails 6.0.6
Since v3.2.22.5Signature
button(value = nil, options = {}, &block)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.button %>
<% end %>In the example above, if @post is a new record, it will use “Create Post” as button label; otherwise, it uses “Update Post”.
Those labels can be customized using I18n under the helpers.submit key (the same as submit helper) and using %{model} for translation interpolation:
en:
helpers:
submit:
create: "Create a %{model}"
update: "Confirm changes to %{model}"It also searches for a key specific to the given object:
en:
helpers:
submit:
post:
create: "Add %{model}"Examples
button("Create post")
# => <button name='button' type='submit'>Create post</button>
button do
content_tag(:strong, 'Ask me!')
end
# => <button name='button' type='submit'>
# <strong>Ask me!</strong>
# </button>
