Rails 5.2.1.rc1 is giving 'wrong number of arguments (given 3, expected 2)'

[jpawlyn]

Hi. I am getting the error for has_many associations with a through argument. It looks as if this Rails commit added an extra argument alias_tracker to the method ActiveRecord::Associations::JoinDependency#join_constraints and this is perhaps causing the above error?

Gem version: 1.3.3
Ruby version: 2.5.0

@jpawlyn Polyamorous is no longer supported. We absorbed the needed bits into ransack. Do you have this issue in an app using ransack?

@gregmolnar That's right, activeadmin (1.3.0). Any suggestion what I can do to resolve the problem? Thanks

Point it to ransack master, there is a WIP PR(activerecord-hackery/ransack#938) to make it work with Rails 5.2.1, so it should be sorted soon.
