Question

I just renamed my table Client to Person using this command:

class RenameClientsToPeople < ActiveRecord::Migration
  def change
    rename_table :clients, :people
  end
end

I carefully renamed all instances and filenames from client to person and from clients to people. But for some reason my app won’t work anymore. I constantly get errors like this:

SQLite3::SQLException: no such column: projects.person_id: SELECT COUNT(*) FROM "projects" INNER JOIN "people" ON "projects"."person_id" = "people"."person_id" WHERE "people"."user_id" = 1

Can anybody tell me how to fix this?

Maybe I should re-create the Person model from scratch instead of just renaming it?

Answer 1

You also need to rename all your foreign keys from client_id to person_id, and it looks like you’ve neglected to do this. In that migration, you’ll want to do something like this:

class RenameClientsToPeople < ActiveRecord::Migration
  def change
    rename_table :clients, :people
    rename_column :projects, :client_id, :person_id
  end
end

Do that for every column that referenced client_id.
