If "patch", "put", "delete", or another verb + # is used, a hidden input named <tt>_method</tt> is added to + # simulate the verb over post. + # * <tt>:format</tt> - The format of the route the form submits to. + # Useful when submitting to another resource type, like <tt>:json</tt>. + # Skipped if a <tt>:url</tt> is passed. + # * <tt>:scope</tt> - The scope to prefix input field names with and + # thereby how the submitted parameters are grouped in controllers. + # * <tt>:model</tt> - A model object to infer the <tt>:url</tt> and + # <tt>:scope</tt> by, plus fill out input field values. + # So if a +title+ attribute is set to "Ahoy!" then a +title+ input + # field's value would be "Ahoy!". + # If the model is a new record a create form is generated, if an + # existing record, however, an update form is generated. + # Pass <tt>:scope</tt> or <tt>:url</tt> to override the defaults. + # E.g. turn <tt>params[:post]</tt> into <tt>params[:article]</tt>. + # * <tt>:authenticity_token</tt> - Authenticity token to use in the form. + # Override with a custom authenticity token or pass <tt>false</tt> to + # skip the authenticity token field altogether. + # Useful when submitting to an external resource like a payment gateway + # that might limit the valid fields. + # Remote forms may omit the embedded authenticity token by setting + # <tt>config.action_view.embed_authenticity_token_in_remote_forms = false</tt>. + # This is helpful when fragment-caching the form. Remote forms + # get the authenticity token from the <tt>meta</tt> tag, so embedding is + # unnecessary unless you support browsers without JavaScript. + # * <tt>:local</tt> - By default form submits are remote and unobstrusive XHRs. + # Disable remote submits with <tt>local: true</tt>. + # * <tt>:skip_enforcing_utf8</tt> - By default a hidden field named +utf8+ + # is output to enforce UTF-8 submits.
