Model Relations on Rails Console
Posted by: Prachi | 28 Mar 2014 | CommentsWe know that rails console is useful for testing ruby syntax and model queries. Also it is useful for changing server-side data without touching the website.
On Rails console, we can view Model Associations.
There is a simple method reflect_on_all_associations, by using which we
get the model associations array on console.
irb(main):001:0> Patient.reflect_on_all_associations.each do |a|
irb(main):002:1* puts "#{a.macro} => #{a.name}"
irb(main):003:1> end
has_many => tsh_reports
has_many => hbs_ag_reports
=> [#<ActiveRecord::Reflection::AssociationReflection:0x007fd4b4209a78 @macro=:has_many, @name=:tsh_reports, @scope=nil, @options={}, @active_record=Patient(no database connection), @plural_name="tsh_reports", @collection=true>, #<ActiveRecord::Reflection::AssociationReflection:0x007fd4b4bfdd90 @macro=:has_many, @name=:hbs_ag_reports, @scope=nil, @options={}, @active_record=Patient(no database connection), @plural_name="hbs_ag_reports", @collection=true>]
That’s it! We have done.
