Enhance Rails Intellisense in Solargraph

rails.rb

# The following comments fill some of the gaps in Solargraph's understanding of
# Rails apps. Since they're all in YARD, they get mapped in Solargraph but
# ignored at runtime.
#
# You can put this file anywhere in the project, as long as it gets included in
# the workspace maps. It's recommended that you keep it in a standalone file
# instead of pasting it into an existing one.
#
# @!parse
#   class ActionController::Base
#     include ActionController::MimeResponds
#     extend ActiveSupport::Callbacks::ClassMethods
#     extend AbstractController::Callbacks::ClassMethods
#   end
#   class ActiveRecord::Base
#     extend ActiveRecord::QueryMethods
#     extend ActiveRecord::FinderMethods
#     extend ActiveRecord::Associations::ClassMethods
#     extend ActiveRecord::Inheritance::ClassMethods
#     include ActiveRecord::Persistence
#   end
# @!override ActiveRecord::FinderMethods#find
#   @overload find(id)
#     @param id [Integer]
#     @return [self]
#   @overload find(list)
#     @param list [Array]
#     @return [Array<self>]
#   @overload find(*args)
#     @return [Array<self>]
#   @return [self, Array<self>]

Regardless of whether it's right or wrong, I feel that having more modules in the ActiveRecord can really help a lot in the development experience, and thus, I add the following:

extend all modules under Active Record

#   class ActiveRecord::Base
#     extend ActiveRecord::Aggregations

And some other thought...

• Since I have added by using solargraph to select the modules one by one, there should be a programmatic way to deal with the above.
• The yard document seems to tell you whether the function returns a relation or not? (for example, .all function says "ActiveRecord::Scoping::Named::ClassMethods#all Returns an ActiveRecord::Relation scope object") maybe we can use that information to annotate the function?

Not sure whether it is possible or not, any thoughts?

You might be interested on the solargraph-rails gem instead of relying on this ad-hoc config file

There is no "Up vote" so... thanks!

This doesn't appear to have made a difference for me. I'm just confused at this point.

@Samuelodan I found answer in the entire rails thread castwide/solargraph#87

you might need to install docs. in my case what helped me was

gem install yard
yard docs
bundle add solargraph solargraph-rails
solargraph config

.solargraph.yml
