Ruby on Rails SubList Plugin

Ruby on Rails SubList Plugin is a great tool for creating dynamic lists of related models on a single editing page. If you have models with one or more has_many relationships with other models, this plugin is a perfect solution for you. With the use of AJAX for adding and removing "sub-forms", you can create a hassle-free editing experience for your users.

The plugin allows you to present a single edit page that creates/edits both the parent model as well as all of the children. This makes it very convenient for the user to manage all related models on a single page. The usage of this plugin is pretty simple and straightforward.

To use this plugin, all you have to do is place the sub_list directory in the vendor/plugins directory of your application. Then, in the controller where you wish to display the sub list, add the following lines of code:

include UIEnhancements::SubList
helper :SubList
sub_list 'SubModel', 'parent' do |new_research_student|
#Place any construction (ie. defaults) required here
end

Make sure to replace 'SubModel' with the class name of the sub model you want to make available and 'parent' with the parent object. For example, if you want to display a sub list of Dogs for each person in your Person controller, you would use 'Dog' as the sub model and 'person' as the parent. It is expected that the @person variable exists and contains a has_many relationship named 'dogs'.

Overall, Ruby on Rails SubList Plugin is a great addition to any Rails project that involves related models. Its ease of use and convenience make it a must-have for developers who want to provide a smooth editing experience for their users.
