2.7.3 Inheritance and specify table_name_prefix does not work ( Ruby on rails )

[YumaInaura]

When super_users table exists in sqlite

class Super < ApplicationRecord
  # does not work
  self.table_name_prefix = 'super_'

  # work
  # self.table_name = 'super_users'
end

class User < Super
  # does not work
  # self.table_name_prefix = 'super_'

  # work
  # self.table_name = 'super_users'
end

# class User < ApplicationRecord
  # work
  # self.table_name_prefix = 'super_'
# end

command

$ bundle exec annotate app/models/user.rb
Model files unchanged.

Could you clarify what "does not work" mean?

Hello!
I ran into this issue myself using a namespaced model in a standard Ruby on Rails 5.2 application.
What the OP is saying that the table_name is not including the table_name_prefix .

In the example above, the expected table_name is super_users but users is being returned instead.
If you do rails g model super/user it should output the following files...

The problem is that the method table_name does not include the prefix super_.

Again, this may be an issue stemming from rails/rails#21476

app/models/super.rb

class Super < ApplicationRecord
  self.table_name_prefix = 'super_'
end

app/models/super/user.rb

module
  class User < ApplicationRecord
  end
end

PR is welcome.

another way to fix it:
In base model:
def self.table_name
self.prefix_str + self.class_name.underscore.pluralize
end
and it works :)

With even the latest version, I'm having trouble getting annotate to annotate some models. It's very strange, because it annotates almost all of the models in my project fine, but it skips a few.

Unable to annotate app/models/metabase_dashboard.rb: Mysql2::Error: Table 'dbname.metabase_dashboards' doesn't exist
Unable to annotate app/models/metabase_dashboard.rb: no implicit conversion of nil into Array
