associationist's Issues

Roadmap

  • 多组数据 共用preloader
  • 条件加载关联
  • 支持scope

display friendly error message when calling eager_load

Since a virtual association does not involve actual relations among tables, and eager_load makes use of join, it cannot be eager_loaded.

Raise when eager_load is triggered. This can be achieved by overriding the check_eager_loadable! on Reflection.

Rails couldn't find a valid model when using `scope` with `includes`

Firstly ❤️ the idea of this Gem, it's perfect for a need I came across today and a really nice implementation.

On Rails 7.0.4 I've defined the following in my model:

include Associationist::Mixin.new(
    name: :surfaced_values,
    scope: lambda() { |entry|
      Properties::Value.joins(:property).where(value_ownable: entry).merge(Property.surfaced)
    },
    type: :collection
  )

If I do Entry.last.surfaced_values it works as expected.

However if I do Entry.includes(:surfaced_values).last I get this error:

Rails couldn't find a valid model for SurfacedValue association. Please provide the :class_name option on the association declaration. If :class_name is already provided, make sure it's an ActiveRecord::Base subclass.

If I add class_name: 'Properties::Value' it gives me the same error.
