Starts a form tag that points the action to an url configured with
url_for_options just like ActionController::Base#url_for. The
method for the form defaults to POST.
Options
-
:multipart- If set to true, the enctype is set to âmultipart/form-dataâ. -
:method- The method to use when submitting the form, usually either âgetâ or âpostâ. If âpatchâ, âputâ, âdeleteâ, or another verb is used, a hidden input with name_methodis added to simulate the verb over post. -
:authenticity_token- Authenticity token to use in the form. Use only if you need to pass custom authenticity token string, or to not add authenticity_token field at all (by passingfalse). Remote forms may omit the embedded authenticity token by settingconfig.action_view.embed_authenticity_token_in_remote_forms = false. This is helpful when you're fragment-caching the form. Remote forms get the authenticity token from themetatag, so embedding is unnecessary unless you support browsers without JavaScript. -
:remote- If set to true, will allow the Unobtrusive JavaScript drivers to control the submit behavior. By default this behavior is an ajax submit. -
:enforce_utf8- If set to false, a hidden input with name utf8 is not output. -
Any other key creates standard HTML attributes for the tag.
