Rails 4 - 通过 link_to 传递参数? [英] Rails 4 - Passing Params via link_to?

问题描述

我有一个表单 - 根据用户单击哪个链接来显示表单，我希望将不同的隐藏参数传递给记录并在提交时保存.有没有很好的方法来做到这一点?提前致谢！

I have a single form - depending which link the user clicks to display the form, I want different hidden params to be passed to the record and saved upon submission. Is there a nice way to do this? Thanks in advance!

例如:

<%= link_to 'General Request', new_request_path %>

<%= link_to 'Project Request', new_request_path %> ### -> set request.project = true

<%= link_to 'Administrative Request', new_request_path %>  ### -> set request.admin = true

推荐答案

对于您的示例，您可以使用:

For your examples, you'd use:

<%= link_to 'Project Request', new_request_path(project: true) %>

这会产生一个像 http://127.0.0.1:3000/request?project=true

和

<%= link_to 'Administrative Request', new_request_path(admin: true) %>

这会产生一个像 http://127.0.0.1:3000/request?admin=true
