Rails 控制器重定向到一个没有键参数的动作

Question

I would like to redirect from one action to another in a same controller.

Suppose I have a private method my_params that returns an ActionController::Parameters instance. It looks like { some_param: 'a', another_param: 'b' } .

Let's say I want to redirect from :action_1 from :action_2 passing params .

When I try to do redirect_to :action, my_params , Rails complains:

syntax error, unexpected end-of-input, expecting keyword_end

Normally, I would write something like,

redirect_to :action, some_param: 'a', another_param: 'b'`

but I cannot do so in this case, because I want to pass my_params .

Is there a Rails way to do this? Or any other suggestions?

Edit

This is not a duplicate because I want to pass in a param that is already an instance of ActionController::Parameters .

您可以将当前的my_params参数散列传递给redirect_to方法，并且只更新（ merge ）您想要更改的值。

redirect_to my_params.merge(action: :action_1)
