在 Rails 中渲染 HTML 而不实际显示它
我当前的项目要求我组装一个包含 HTML 和纯文本模板的 .zip 文件，供用户下载，以便导入到电子邮件营销程序中。
我继承了这个项目，目前代码使用“假”模型（即不直接与数据库表相关的模型），其中它将整个模板存储在字符串中，使用动态变量来填充某些地区。然后，“假”模型有一个创建 zip 文件的方法。
在我看来，必须有更好的方法来做到这一点。我想知道是否有办法将模板移动到 .erb/haml 文件中，然后编写一个方法来填充该文件以准备压缩？基本上，有没有一种方法可以渲染 HTML 和文本文件，而无需实际显示它们？
感谢您的任何帮助。
My current project requires me to assemble a .zip file containing HTML and text-only templates for a user to download, for importing into an email marketing program.
I've inherited this project, and currently the code uses a "fake" model (that is a model that does not directly correlate to a database table), in which it stores the entire template in a string, using dynamic variables to populate certain areas. The "fake" model then has a method for creating a zip file.
It seems to me that there has to be a better way to do this. I was wondering if there was a way to move the template into a .erb/haml file, and then write a method that would populate the file in preparation for being zipped up? Basically, is there a way to render an HTML and text file, without actually having to display them?
Thanks for any help.

只需编写操作和视图来正常渲染 html 和文本，然后使用 render_to_string 方法将内容分配给字符串
http://apidock.com/rails/ActionController/Base/render_to_string
然后您可以运行 Model 方法（希望是类方法）以使用实例变量中现在的内容创建 zip 文件
Just write the action and view to render the html and text as normal then use the render_to_string method to assign the content to strings

Then you can run the Model method (hopefully a Class method) to create the zip file using the content you now have in instance variables
