无法修改冻结的哈希 - rails 6 heroku
can't modify frozen Hash - rails 6 heroku
更新到 Rails 6 并推送到 Heroku 后，我收到此错误。我找不到任何类似的问题，也不明白错误的意思。
我已确认数据库、用户名、密码和主机位置都是准确的。

似乎引用了 sidekiq 初始值设定项的第 6 行，但我没有发现任何可疑之处。事实上，自从几年前设置以来，它真的没有改变过：
if Rails.env.production?
require 'sidekiq/web'
Sidekiq.configure_server do |config|
ActiveRecord::Base.configurations[Rails.env.to_s]['pool'] = 30
end
end
sidekiq.yml:
development:
:concurrency: 5
production:
:concurrency: 20
:queues:
- default
- mailers
过程文件
web: bundle exec puma -p $PORT ./config.ru
web: bundle exec puma -C config/puma.rb
redis: redis-server
worker: bundle exec sidekiq -e production -C config/sidekiq.yml
看起来配置散列自此提交后已被冻结：https://github.com/rails/rails/commit/2291d4a94fd3aff61c77d1a2ad1e6186ed4c80a2。 ActiveRecord::Base.configurations[Rails.env.to_s]['pool'] = 30 在你的 Sidekiq 初始化器中试图改变冻结的散列。
如果您在 config.database.yml 文件中配置数据库，您可以在那里添加或更新生产池的大小，并删除整个 Sidekiq.configure_server 块：
production:
username: <%= ENV['DATABASE_USERNAME'] %>
password: <%= ENV['DATABASE_PASSWORD'] %>
pool: 30
如果您完全通过 DATABASE_URL 环境变量配置数据库，则只需确保在 URL:
末尾指定池大小
postgresql://username:password@host:5432/database-name?pool=30
更多信息在这里：https://edgeguides.rubyonrails.org/configuring.html#configuring-a-database
Sidekiq 初始化程序：
require 'sidekiq/web' if Rails.env.production?
更新到 Rails 6 并推送到 Heroku 后，我收到此错误。我找不到任何类似的问题，也不明白错误的意思。
我已确认数据库、用户名、密码和主机位置都是准确的。

似乎引用了 sidekiq 初始值设定项的第 6 行，但我没有发现任何可疑之处。事实上，自从几年前设置以来，它真的没有改变过：
if Rails.env.production?
require 'sidekiq/web'
Sidekiq.configure_server do |config|
ActiveRecord::Base.configurations[Rails.env.to_s]['pool'] = 30
end
end
sidekiq.yml:
development:
:concurrency: 5
production:
:concurrency: 20
:queues:
- default
- mailers
过程文件
web: bundle exec puma -p $PORT ./config.ru
web: bundle exec puma -C config/puma.rb
redis: redis-server
worker: bundle exec sidekiq -e production -C config/sidekiq.yml
看起来配置散列自此提交后已被冻结：https://github.com/rails/rails/commit/2291d4a94fd3aff61c77d1a2ad1e6186ed4c80a2。 ActiveRecord::Base.configurations[Rails.env.to_s]['pool'] = 30 在你的 Sidekiq 初始化器中试图改变冻结的散列。
如果您在 config.database.yml 文件中配置数据库，您可以在那里添加或更新生产池的大小，并删除整个 Sidekiq.configure_server 块：
production:
username: <%= ENV['DATABASE_USERNAME'] %>
password: <%= ENV['DATABASE_PASSWORD'] %>
pool: 30
如果您完全通过 DATABASE_URL 环境变量配置数据库，则只需确保在 URL:
postgresql://username:password@host:5432/database-name?pool=30

Sidekiq 初始化程序：
require 'sidekiq/web' if Rails.env.production?
