Yuri-ita

🚧 This gem is in active development 🚧

The yuri-ita (揺り板), Japanese for "rocking plate", is a traditional wooden gold pan used in Japan.

Check out a demo application showcasing some of the capabilities of the library.

What is Yuri-ita?

The goal of this library is to provide developers and designers with a powerful set of tools to build expressive user interfaces for filtering, searching, and sorting data in Ruby on Rails. It does not provide UI components but instead offers a simple API that allows you to build your own UI.

Yuri-ita's primary interface is through a text-based query language. This provides a means to create behavior as simple or as complex as your needs require.

is:published author:eebs category:rails sort:created-asc "advanced filtering"

Yuri-ita allows you to define what each input means within your application. is:published may mean different things in different applications, or even in different interfaces within the same application. You define what query to run for each input and Yuri-ita handles combining all the inputs into a valid result.

You can create static filters that always run the same query:

input = Yuriita::Inputs::Expression.new("is", "published")

Yuriita::ExpressionFilter.new(input: input) do |relation|
  relation.where(published: true)
end

You can also define dynamic filters that use the input term in the query itself:

Yuriita::DynamicFilter.new(qualifier: "author") do |relation, input|
  relation.joins(:author).where(users: {username: input.term})
end

Some inputs can be specified multiple times in the query input and Yuri-ita combines them using AND or OR logical expressions depending on how you've configured the filter definitions. For example, category:rails category:ruby could be defined such that it returns posts in either the "rails" or "ruby" category.

Other features such as searching, sorting, and generating custom UI are possible with Yuri-ita.
