当我运行rake db：seed时，我一直得到＆＃34; rake aborted！ ActionView :: Template ::错误：缺少链接到的主机！ ＆＃34;

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。 但是当我跑步时

rake db:seed  

我仍在继续

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/ database.yml的

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: <%= ****** %>

非常感谢任何帮助。谢谢。

Answer 1

我猜你试图用种子填充开发环境，如果是这种情况，那么试试这个

rake db:seed RAILS_ENV=development

Answer 2

我明白了。我忘了回答抱歉。解决方案可能因每个人的特定错误而异。但对我来说，我必须在以下文件中进行以下更改。

在application.yml中我添加了

SMTP_HOST: 'localhost:3000'

在development.rb中我添加了

config.action_mailer.raise_delivery_errors = false

播种完成。
