在 Rails 中生成 url 时替换 example.org

问题描述

重现步骤：

rails new testurl
cd testurl
在 config/routes.rb

添加

resources :tests,only: [:index]

在 app/views/test/test.html.erb 中创建一个内容为 <%= tests_url %> 的新文件。

我需要做的是将此视图呈现为 HTML 字符串，为此我执行了以下操作：

rails c
然后运行 ApplicationController.render(template: 'test/test')

运行上面的代码给了我以下结果：

irb(main):006:0> ApplicationController.render(template: 'test/test')
  Rendering layout layouts/application.html.erb
  Rendering test/test.html.erb within layouts/application
  Rendered test/test.html.erb within layouts/application (Duration: 0.6ms | Allocations: 127)
Everything's up-to-date. nothing to do
  Rendered layout layouts/application.html.erb (Duration: 12.4ms | Allocations: 3390)
=> "<!DOCTYPE html>\n<html>\n  <head>\n    <title>Testurl</title>\n    <Meta name=\"viewport\" content=\"width=device-width,initial-scale=1\">\n    <Meta name=\"csrf-param\" content=\"authenticity_token\" />\n<Meta name=\"csrf-token\" content=\"Cl5oXyPFrAsZl_s3m_fO1ELVkFtUajlnI30AOZ0BB9LJpMbXnGjgX1Ng_JvQhcFo3VMD67a467Cs4mjcB_ODmA\" />\n    \n\n    <link rel=\"stylesheet\" media=\"all\" href=\"/assets/application.debug-ead91a25923de99455378da7f1f1bb5a6839a249af27af911ec2b81709b046b7.css\" data-turbolinks-track=\"reload\" />\n    <script src=\"/packs/js/application-f826770d917d8a37c1d8.js\" data-turbolinks-track=\"reload\"></script>\n  </head>\n\n  <body>\n    http://example.org/tests\n\n  </body>\n</html>\n"

如您所见，<%= tests_url %> 呈现为 http://example.org/tests。这个 http://example.org 在哪里定义？以及如何更换？

我尝试在新的 Rails 应用中搜索 example.org，并在 config/initializers/application_controller_renderer.rb 中找到以下代码：

# Be sure to restart your server when you modify this file.

# ActiveSupport::Reloader.to_prepare do
#   ApplicationController.renderer.defaults.merge!(
#    http_host: 'example.org',#    https: false
#  )
# end

我尝试取消注释代码并将其替换为以下内容：

# Be sure to restart your server when you modify this file.

ActiveSupport::Reloader.to_prepare do
  ApplicationController.renderer.defaults.merge!(
    http_host: 'google.com',https: true
  )
end

然后，我重新启动了应用程序和 rails 控制台。

但仍然运行 ApplicationController.render(template: 'test/test') 仍然给我 http://example.org 我期望它是 https://google.com。似乎是什么问题？

环境：

Ruby 2.7.2
Rails 6.1.3

解决方法

我还没有找到如何全局更改 example.org，但下面的解决方案对我来说已经足够了。

renderer = ApplicationController.renderer.new(
  http_host: 'google.com',https: true
)

renderer.render(template: 'test/test')

现在它返回了：

irb(main):016:0> renderer.render(template: 'test/test')
  Rendering layout layouts/application.html.erb
  Rendering test/test.html.erb within layouts/application
  Rendered test/test.html.erb within layouts/application (Duration: 0.2ms | Allocations: 44)
Everything's up-to-date. Nothing to do
  Rendered layout layouts/application.html.erb (Duration: 15.7ms | Allocations: 3133)
=> "<!DOCTYPE html>\n<html>\n  <head>\n    <title>Testurl</title>\n    <meta name=\"viewport\" content=\"width=device-width,initial-scale=1\">\n    <meta name=\"csrf-param\" content=\"authenticity_token\" />\n<meta name=\"csrf-token\" content=\"M-u_LLixMIE-SgRpRiY0I-iqZiwvg2JAnJ14Oreqb8HCoQw5s7g00qPLMPg8kmmOImj1T-tekks_zMpMf0W_mQ\" />\n    \n\n    <link rel=\"stylesheet\" media=\"all\" href=\"/assets/application.debug-ead91a25923de99455378da7f1f1bb5a6839a249af27af911ec2b81709b046b7.css\" data-turbolinks-track=\"reload\" />\n    <script src=\"/packs/js/application-f826770d917d8a37c1d8.js\" data-turbolinks-track=\"reload\"></script>\n  </head>\n\n  <body>\n    https://google.com/tests\n\n  </body>\n</html>\n"

现在将 http://example.com 替换为 https://google.com。
