+ # # =>

+ # <input type="text" name="cat[but_in_forms_they_can]">
+ # </form>
+ #
+ # The parameters in the forms are accessible in controllers according to
+ # their name nesting. So inputs named +title+ and <tt>post[title]</tt> are
+ # accessible as <tt>params[:title]</tt> and <tt>params[:post][:title]</tt>
+ # respectively.
+ #
+ # By default +form_with+ attaches the <tt>data-remote</tt> attribute
+ # submitting the form via an XMLHTTPRequest in the background if an
+ # Unobtrusive JavaScript driver, like rails-ujs, is used. See the
+ # <tt>:local</tt> option for more.
+ #
+ # For ease of comparison the examples above left out the submit button,
+ # as well as the auto generated hidden fields that enable UTF-8 support
+ # and adds an authenticity token needed for cross site request forgery
+ # protection.
+ #
+ # ==== +form_with+ options
+ #
+ # * <tt>:url</tt> - The URL the form submits to. Akin to values passed to
+ # +url_for+ or +link_to+. For example, you may use a named route
+ # directly. When a <tt>:scope</tt> is passed without a <tt>:url</tt> the
+ # form just submits to the current URL.
+ # * <tt>:method</tt> - The method to use when submitting the form, usually
+ # either "get" or "post". 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. Set to true to skip the field.
+ # * <tt>:builder</tt> - Override the object used to build the form.
+ # * <tt>:id</tt> - Optional HTML id attribute.
+ # * <tt>:class</tt> - Optional HTML class attribute.
+ # * <tt>:data</tt> - Optional HTML data attributes.
+ # * <tt>:html</tt> - Other optional HTML attributes for the form tag.
+ #
+ # === Examples
+ #
+ # When not passing a block, +form_with+ just generates an opening form tag.
+ #
+ # <%= form_with(model: @post, url: super_posts_path) %>
+ # <%= form_with(model: @post, scope: :article) %>
+ # <%= form_with(model: @post, format: :json) %>
+ # <%= form_with(model: @post, authenticity_token: false) %> # Disables the token.
+ #
+ # For namespaced routes, like +admin_post_url+:
+ #
+ # <%= form_with(model: [ :admin, @post ]) do |form| %>
+ # ...
+ # <% end %>
+ #
+ # If your resource has associations defined, for example, you want to add comments
+ # to the document given that the routes are set correctly:
+ #
+ # <%= form_with(model: [ @document, Comment.new ]) do |form| %>
+ # ...
+ # <% end %>
+ #
+ # Where <tt>@document = Document.find(params[:id])</tt>.
+ #
+ # When using labels +form_with+ requires setting the id on the field being
+ # labelled:
+ #
+ # <%= form_with(model: @post) do |form| %>
+ # <%= form.label :title %>
+ # <%= form.text_field :title, id: :post_title %>
+ # <% end %>
+ #
+ # See +label+ for more on how the +for+ attribute is derived.
+ #
+ # === Mixing with other form helpers
+ #
+ # While +form_with+ uses a FormBuilder object it's possible to mix and
+ # match the stand-alone FormHelper methods and methods
+ # from FormTagHelper:
+ #
+ # <%= form_with scope: :person do |form| %>
+ # <%= form.text_field :first_name %>
+ # <%= form.text_field :last_name %>
+ #
+ # <%= text_area :person, :biography %>
+ # <%= check_box_tag "person[admin]", "1", @person.company.admin? %>
+ #
+ # <%= form.submit %>
+ # <% end %>
+ #
+ # Same goes for the methods in FormOptionHelper and DateHelper designed
+ # to work with an object as a base, like
+ # FormOptionHelper#collection_select and DateHelper#datetime_select.
+ #
+ # === Setting the method
+ #
+ # You can force the form to use the full array of HTTP verbs by setting
+ #
+ # method: (:get|:post|:patch|:put|:delete)
+ #
+ # in the options hash. If the verb is not GET or POST, which are natively
+ # supported by HTML forms, the form will be set to POST and a hidden input
+ # called _method will carry the intended verb for the server to interpret.
+ #
+ # === Setting HTML options
+ #
+ # You can set data attributes directly in a data hash, but HTML options
+ # besides id and class must be wrapped in an HTML key:
+ #
+ # <%= form_with(model: @post, data: { behavior: "autosave" }, html: { name: "go" }) do |form| %>
+ # ...
+ # <% end %>
+ #
+ # generates
+ #
+ # <form action="/posts/123" method="post" data-behavior="autosave" name="go">
+ # <input name="_method" type="hidden" value="patch" />
+ # ...
+ # </form>
+ #
+ # === Removing hidden model id's
+ #
+ # The +form_with+ method automatically includes the model id as a hidden field in the form.
+ # This is used to maintain the correlation between the form data and its associated model.
+ # Some ORM systems do not use IDs on nested models so in this case you want to be able
+ # to disable the hidden id.
+ #
+ # In the following example the Post model has many Comments stored within it in a NoSQL database,
+ # thus there is no primary key for comments.
+ #
+ # <%= form_with(model: @post) do |form| %>
+ # <%= form.fields(:comments, skip_id: true) do |fields| %>
+ # ...
+ # <% end %>
+ # <% end %>
+ #
+ # === Customized form builders
+ #
+ # You can also build forms using a customized FormBuilder class. Subclass
+ # FormBuilder and override or define some more helpers, then use your
+ # custom builder. For example, let's say you made a helper to
+ # automatically add labels to form inputs.
+ #
+ # <%= form_with model: @person, url: { action: "create" }, builder: LabellingFormBuilder do |form| %>
+ # <%= form.text_field :first_name %>
+ # <%= form.text_field :last_name %>
+ # <%= form.text_area :biography %>
+ # <%= form.check_box :admin %>
+ # <%= form.submit %>
+ # <% end %>
+ #
+ # In this case, if you use:
+ #
+ # <%= render form %>
+ #
+ # The rendered template is <tt>people/_labelling_form</tt> and the local
+ # variable referencing the form builder is called
+ # <tt>labelling_form</tt>.
+ #
+ # The custom FormBuilder class is automatically merged with the options
+ # of a nested +fields+ call, unless it's explicitly set.
+ #
+ # In many cases you will want to wrap the above in another helper, so you
+ # could do something like the following:
+ #
+ # def labelled_form_with(**options, &block)
+ # form_with(**options.merge(builder: LabellingFormBuilder), &block)
