mysql - 当我运行 rake db :seed, 时，我不断收到 "rake aborted! ActionView::Template::Error: Missing host to link to! "

Question

我正在尝试在本地主机上运行我们公司的产品源代码。我试过放置

config.action_mailer.default_url_options = { host: "localhost:3000" }

在所有 development.rb、test.rb 和 production.rb 中。但是当我跑的时候

rake db:seed  

我还在坚持

ActionView::Template::Error: Missing host to link to! Please provide the :host parameter, set default_url_options[:host], or set :only_path to true.

我正在按照编辑中的建议添加我的 config/database.yml 文件配置/数据库.yml

default: &default
  adapter: mysql2
  encoding: utf8
  pool: 5
  username: root
  password: ******
  socket: /var/run/mysqld/mysqld.sock

development:
  <<: *default
  database: company_development

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
  <<: *default
  database: coompany_test

# As with config/secrets.yml, you never want to store sensitive information,
# like your database password, in your source code. If your source code is
# ever seen by anyone, they now have access to your database.
#
# Instead, provide the password as a unix environment variable when you boot
# the app. Read http://guides.rubyonrails.org/configuring.html#configuring-a-database
# for a full rundown on how to provide these environment variables in a
# production deployment.
#
# On Heroku and other platform providers, you may have a full connection URL
# available as an environment variable. For example:
#
#   DATABASE_URL="mysql2://myuser:mypass@localhost/somedatabase"
#
# You can use this database configuration with:
#
#   production:
#     url: <%= ENV['DATABASE_URL'] %>
#
production:
  <<: *default
  database: company_production
  username: company
  password: <%= ****** %>

任何帮助将不胜感激。谢谢。

我猜你正试图用种子填充开发环境，如果是这样的话试试这个

rake db:seed RAILS_ENV=development
