ruby-on-rails - 带有 Postgresql 扩展的 Heroku CI

Question

我正在尝试使用 Heroku 的 CI 来运行我的 Rails 应用程序的测试，但在尝试加载我的 structure.sql 时遇到了问题。文件。

-----> Preparing test database
       Running: rake db:schema:load_if_ruby
       db:schema:load_if_ruby completed (3.24s)
       Running: rake db:structure:load_if_sql
       psql:/app/db/structure.sql:28: ERROR:  must be owner of extension plpgsql
       rake aborted!
       failed to execute:
       psql -v ON_ERROR_STOP=1 -q -f /app/db/structure.sql d767koa0m1kne1
       Please check the output above for any errors and make sure that `psql` is installed in your PATH and has proper permissions.

       Tasks: TOP => db:structure:load
       (See full trace by running task with --trace)
 !
 !     Could not prepare database for test
 !

这里的相关行是:

psql:/app/db/structure.sql:28: ERROR: must be owner of extension plpgsql rake aborted!

Structure.sql 包含这一行:

COMMENT ON EXTENSION plpgsql IS 'PL/pgSQL procedural language';

关于如何在 Heroku 的 CI 上进行这项工作的任何想法？

Answer 1

最终覆盖 db:structure:dump删除 COMMENT ON ...声明:

namespace :db do
  namespace :structure do
    task dump: [:environment, :load_config] do
      filename = ENV["SCHEMA"] || File.join(ActiveRecord::Tasks::DatabaseTasks.db_dir, "structure.sql")
      sql = File.read(filename).each_line.grep_v(/\ACOMMENT ON EXTENSION.+/).join

      File.write(filename, sql)
    end
  end
end
