module Sequel::Plugins::Forme::SequelForm

  1. lib/sequel/plugins/forme.rb

This module extends all Forme::Form instances that use a Sequel::Model instance as the form's obj.


Public Instance

  1. form
  2. humanize
  3. subform

Public Instance methods

form (attr={}, &block)

Use the post method by default for Sequel forms, unless overridden with the :method attribute.

[show source]
# File lib/sequel/plugins/forme.rb, line 22
def form(attr={}, &block)
  attr[:class] = ::Forme.merge_classes(attr[:class], "forme", obj.forme_namespace)
  super(attr, &block)
humanize (s)

Call humanize on a string version of the argument if String#humanize exists. Otherwise, do some monkeying with the string manually.

[show source]
# File lib/sequel/plugins/forme.rb, line 30
def humanize(s)
  s = s.to_s
  s.respond_to?(:humanize) ? s.humanize : s.gsub(/_id$/, "").gsub(/_/, " ").capitalize
subform (association, opts={}, &block)

Handle nested association usage. The association should be a name of the association for the form's obj. Inside the block, calls to the input and inputs methods for the receiver treat the associated object as the recevier's obj, using name and id attributes that work with the Sequel nested_attributes plugin.

The following options are currently supported:


Automatically call inputs with the given values. Using this, it is not required to pass a block to the method, though it will still work if you do.


When using the :grid option, this allows you to specify options to pass to the table InputsWrapper.


Overrides the default :legend used (which is based on the association name). You can also use a proc as the value, which will called with each associated object (and the position in the associated object already for *_to_many associations), and should return the legend string to use for that object.


Sets up a table with one row per associated object, and one column per field.


When using the :grid option, override the labels that would be created via the :inputs option. If you are not providing an :inputs option or are using a block with additional inputs, you should specify this option.


Skip adding a hidden primary key field for existing objects.
