我尝试使用Heroku的CI运行我的Rails应用程序测试，但在尝试加载structure.sql文件时遇到了问题。< / p>
-----> Preparing test database

! Could not prepare database for test

这里的相关行是：
psql：/app/db/structure.sql:28:ERROR:必须是扩展程序plpgsql的所有者 耙子流产了！
Structure.sql包含以下行：
COMMENT ON EXTENSION plpgsql IS 'PL/pgSQL procedural language';
有关如何使用Heroku的CI的任何想法？
答案 0 :(得分：4)
结束覆盖COMMENT ON ...以删除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

另一种解决方法是添加类似
的内容if Rails.env.development?
ActiveRecord::Tasks::DatabaseTasks.structure_load_flags = ["-v", "ON_ERROR_STOP=0"]
end
在执行db:structure:load之前初始化/任务管道中的任何位置。
答案 2 :(得分：2)
如果Kyle的解决方案不够，并且错误不是仅由扩展评论引起的，而是由实际扩展安装引起的，您仍然可以采取艰难的方式并将其添加到初始化程序中：
# This is a temporary workaround for the Rails issue #29049.
# It could be safely removed when the PR #29110 got merged and released
# to use instead IGNORE_PG_LOAD_ERRORS=1.
module ActiveRecord
module Tasks
class PostgreSQLDatabaseTasks
ON_ERROR_STOP_1 = 'ON_ERROR_STOP=0'.freeze
end
end
end
注意：这不是Heroku特有的，而是更广泛的Rails 5.1问题
答案 3 :(得分：0)
有两个解决方案。如前所述，首先禁用ON_ERROR_STOP功能。无论环境如何，它都会有所帮助。自定义耙任务：
namespace :db do
namespace :structure do
# This little task is a workaround for a problem introduced in Rails5. Most specificaly here
# https://github.com/rails/rails/blob/5-1-stable/activerecord/lib/active_record/tasks/postgresql_database_tasks.rb#L77
# When psql encounters an error during loading of the structure it exits at once with error code 1.
# And this happens on heroku. It renders review apps and heroku CI unusable if you use a structure instead of a schema.
# Why?
# Our `db/structure.sql` contains entries like `CREATE EXTENSION` or `COMMENT ON EXTENSION`.
# Zylion of extensions on heroku are loaded in template0, so "our" db also has them, but because of that
# only a superuser (or owner of template0) has access to them - not our heroku db user. For that reason
# we can neither create an extension (it already exists, but that is not a problem, because dump contains IF NOT EXIST)
# nor comment on it (and comments don't have IF NOT EXIST directive). And that's an error which could be safely ignored
# but which stops loading of the rest of the structure.
desc "Disable exit-on-error behaviour when loading db structure in postgresql"
task disable_errors: :environment do
ActiveRecord::Tasks::DatabaseTasks.structure_load_flags = ["-v", "ON_ERROR_STOP=0"]
end
end
end
# And use it like so:
bin/rails db:structure:disable_errors db:structure:load
在我看来，另一种选择（如果仅涉及Heroku则更好）是在in-dyno计划（https://devcenter.heroku.com/articles/heroku-ci-in-dyno-databases）中使用PostgreSQL，这基本上是一个位于dyno中的数据库实例，因此完全访问它。同样，测试套件应该明显更快，因为我们使用本地主机连接，而不是通过网络。要启用它，请将您的app.json内容更改为具有以下条目：
{
"environments": {
"test": {
"addons": [
"heroku-postgresql:in-dyno"
]
}
}
}
