主机链接丢失!请为Rails 4提供:host参数 [英] Missing host to link to! Please provide the :host parameter, for Rails 4
问题描述
缺少要链接的主机!请提供:host参数,设置
default_url_options [:host],或将:only_path设置为true
Missing host to link to! Please provide the :host parameter, set default_url_options[:host], or set :only_path to true
我随机得到有时会出现此错误,通常重新启动服务器会解决此问题一段时间,然后再次出现。
我已经在开发和test.rb文件中添加了
config.action_mailer.default_url_options = localhost:3000
。
I randomly get this error at time, generally restarting the server fixes the issue for a while, and then it shows up again.
I have added
config.action_mailer.default_url_options = "localhost:3000"
, in the development and test.rb files.
此外,我在一个模块中使用了 include Rails.application.routes.url_helpers
来访问路线,我读到这可能是我得到这些错误的原因,但是删除这些错误将使我无法访问路由。
该模块用于datatables gem。
Also, I have used include Rails.application.routes.url_helpers
in one module to get access to the routes, I read this could be the reason I get these errors but removing it will leave me with no access to the routes.
The module is for the datatables gem.
推荐答案
对于Rails 5,使用:
For Rails 5, use:
Rails.application.routes.default_url_options[:host] = "XXX"
您可以将其放入 config / environments /
文件(或任何其他初始化程序),例如在 config / routes.rb
的开头。
You can put this in a config/environments/
file (or any other initializer), or e.g. at the beginning of config/routes.rb
.
