【问题描述】:
什么会导致 Rails 每次都运行迁移?
我正在部署到一个 qa 环境,并且每次都会运行迁移,就好像 rails 正在重新设置整个数据库一样。
这是我的config/environments/qa.rb
Backend::Application.configure do
# Settings specified here will take precedence over those in config/application.rb
config.assets.compile = true
config.serve_static_assets = false
# In the development environment your application's code is reloaded on
# every request. This slows down response time but is perfect for development
# since you don't have to restart the web server when you make code changes.
config.cache_classes = false
# Log error messages when you accidentally call methods on nil.
config.whiny_nils = true
# Show full error reports and disable caching
config.consider_all_requests_local = true
config.action_controller.perform_caching = false
# Don't care if the mailer can't send
config.action_mailer.raise_delivery_errors = false
# Print deprecation notices to the Rails logger
config.active_support.deprecation = :log
# Only use best-standards-support built into browsers
config.action_dispatch.best_standards_support = :builtin
# Raise exception on mass assignment protection for Active Record models
config.active_record.mass_assignment_sanitizer = :strict
# Log the query plan for queries taking more than this (works
# with SQLite, MySQL, and PostgreSQL)
config.active_record.auto_explain_threshold_in_seconds = 0.5
# Do not compress assets
config.assets.compress = false
# Expands the lines which load the assets
config.assets.debug = true
# ActionMailer Config
config.action_mailer.default_url_options = { :host => 'localhost:3002' }
config.action_mailer.delivery_method = :smtp
# change to true to allow email to be sent during development
config.action_mailer.perform_deliveries = true
config.action_mailer.raise_delivery_errors = true
config.action_mailer.default :charset => "utf-8"
end
编辑:Rails 4.0 和 3.2 - rake db:migrate 每次都会运行所有迁移。
编辑:使用 capistrano 进行部署:cap qa deploy
【问题讨论】:
-
这发生在 Rails 4.0 和 3.2 上。
-
你是如何部署的?
-
与 capistrano:
cap qa deploy
