How to dynamically call routes helper in rails?

问题:

For example, I have constructed a string called "new_work_path", now I want to call that helper as a method.

I've tried send("new_work_path", vars) and calling the same send from many objects. But I don't think that I've found the right object to call these helpers.

To do object.send("new_work_path", vars), what object should I be looking for?

I've tried to look for this online for a while but couldn't find anything. If anyone can shine some lights on this one, it would be great!

Thanks!

回答1:

try Rails.application.routes.url_helpers.send(...)

回答2:

My bad, as per @tadman suggested, I tried to use send(:new_work_path, args) again and it worked! Must have mistyped it before.

Before finding out that send works right away, I had found another solution which is also of interest:

new_polymorphic_path(Work, args)

Which seems to offer some syntactic sugar as well.
