Question: Is there a way to hook on the tenant switching mechanism?

[michalvalasek]

I'd like to set the Current.tenant automatically on every Apartment::Tenant.switch! call. Is there a way how to do this? Any hook I can use from outside?

@mikecmpbll Thanks, I've seen that PR but I haven't found any doc on how to actually use it. What am I missing?

[mikecmpbll]

it uses Active Support Callbacks. afaicr you can define callbacks as such:

Apartment.set_callback :switch, :after do
  puts "switched"
end

Thank you very much! I’ll create a PR where I add it to the readme - if that’s ok.

With rails 5.2.1 and ruby 2.6.0

When using

Apartment.set_callback :switch, :after do
  puts "switched"
end

I got

initializers/apartment.rb:116:in `<main>': undefined method `set_callback' for Apartment:Module (NoMethodError)

when using

Apartment::Tenant.set_callback :switch, :after do
  puts "switched"
end

I got

initializers/apartment.rb:116: warning: Apartment::Tenant#set_callback at ruby-2.6.0/lib/ruby/2.6.0/forwardable.rb:158 forwarding to private method Apartment::Adapters::PostgresqlSchemaAdapter#set_callback

I just found set_callback mentioned in this issue and this file: https://github.com/influitive/apartment/blob/a4332c3222210b11f5e8c27fa4c1a18b492e9629/lib/apartment/tenant.rb

As anyone faced this issue?

@jean-francois-labbe dirty workaround:

require 'apartment/adapters/abstract_adapter'
Apartment::Adapters::AbstractAdapter.set_callback :switch, :after do
  puts 'switched'
end
