Instead, you provide the names and values manually. # # NOTE: The HTML options disabled, readonly, and multiple can all be treated as booleans. So specifying # :disabled => true will give disabled="disabled". module FormTagHelper extend ActiveSupport::Concern include UrlHelper include TextHelper # 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 "multipart/form-data". # * :method - The method to use when submitting the form, usually either "get" or "post". # If "put", "delete", or another verb is used, a hidden input with name _method # is 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 passing false). If this is a remote form, the authenticity_token will by default # not be included as the ajax handler will get it from the meta-tag (but you can force it to be # rendered anyway in that case by passing true). # * A list of parameters to feed to the URL the form will be posted to. # * :remote - If set to true, will allow the Unobtrusive JavaScript drivers to control the # submit behavior. By default this behavior is an ajax submit. # # ==== Examples # form_tag('/posts') # # =>
# # <%= form_tag('/posts', :remote => true) %> # # => ") end def token_tag(token) if token == false || !protect_against_forgery?
