如何将变量传递给 render_to_string? [英] How to pass variables to render_to_string?

问题描述

尝试执行以下操作

@message = render_to_string ( :sender => sender, :template => "template" )          

但是当在模板中访问@sender 时，结果是 nil:NilClass.仔细检查我是否通过了正确的变量，这完全没问题.也许还有其他方法可以将变量传递给 render_to_string?

But when accessing @sender in template it turns out to be nil:NilClass. Double checked if I pass the right variable and it's totally fine. Maybe there are other way to pass variables to render_to_string?

推荐答案

这可能是您使用的语法.尝试使用 :locals 参数:

It might be the syntax you're using. Try using the :locals argument:

@m = render_to_string :template => "template", :locals => {:sender => sender}

然后你只需要访问sender(没有@)作为模板内的局部变量.

Then you just need to access sender (without an @) as a local variable inside the template.
