ActsAsHasMany mimics a has_many association within an array stored in your ActiveRecord models. It provides a flexible way to define and manage custom associations using array attributes, without relying solely on standard ActiveRecord associations. Additionally, it supports nested forms by mimicking accepts_nested_attributes_for.
Install the gem and add to the application's Gemfile by executing:
$ bundle add acts_as_has_many
If bundler is not being used to manage dependencies, install the gem by executing:
$ gem install acts_as_has_many
Use the acts_as_has_many method to define custom array associations within your model:
class MyModel < ActiveRecord::Base
acts_as_has_many :some_attribute
end
some_attribute is an attrubute with in your model, and is expected to return an Array. It could be of any type jsonb, text, etc.
The gem will look for a class with the same name as the attribute, eg. RelatedObject
You can also specify custom class names for your associations.
class MyModel < ActiveRecord::Base
acts_as_has_many :some_attribute, class_name: 'OtherClass'
end
If you prefer not to create a new class, you can use OpenStruct.
class MyModel < ActiveRecord::Base
acts_as_has_many :some_attribute, class_name: 'OpenStruct'
end
By default, ActsAsHasMany overrides the attribute getter and setter methods. If you prefer to use different attribute, you can specify a custom attribute using the :attribute option:
class MyModel < ActiveRecord::Base
acts_as_has_many :some_attribute, attribute: :some_other_attribute
end
ActsAsHasMany supports nested forms by mimicking accepts_nested_attributes_for, allowing you to work with nested attributes and create more complex forms with ease:
class MyModel < ActiveRecord::Base
acts_as_has_many :some_attributes
acts_as_accepts_nested_attributes_for :some_attributes
end
= f.fields_for :some_attributes, @model.some_attributes |ff|
= ff.text_field :name
This combination enables you to use nested forms for some_attribute.
