redirect_to new_user_path(:id => 1, :contact_id => 3, :name => 'suleman')

routes.rb

 match 'controller_name/action_name' => 'controller_name#action_name', via: [:get, :post], :as => :abc

任何你想重定向参数的控制器如下所示:

redirect_to abc_path(@abc, id: @id), :notice => "message fine" 

如果您正在使用RESTful资源，您可以执行以下操作:

redirect_to action_name_resource_path(resource_object, param_1: 'value_1', param_2: 'value_2')

or
#You can also use the object_id instead of the object
redirect_to action_name_resource_path(resource_object_id, param_1: 'value_1', param_2: 'value_2')

or
#if its a collection action like index, you can omit the id as follows
redirect_to action_name_resource_path(param_1: 'value_1', param_2: 'value_2')

#An example with nested resource is as follows:
redirect_to edit_user_project_path(@user, @project, param_1: 'value_1', param_2: 'value_2')

如果你正在寻找一种方法来传递额外的URL参数(不是控制器，动作，id等)，这里有一个健壮的方法来这样做:

object_path(@object, params: request.query_parameters)

这将传递utm参数或您不想丢失的任何其他附加参数。

redirect_to new_user_path(:id => 1, :contact_id => 3, :name => 'suleman')

从Rails 6开始，您可以简单地调用redirect_to，后跟希望重定向到的路径(如home_path)，然后pass是键-值对的散列。

例子:

redirect_to home_path(name: 'Jason', needs: 'help with rails', help: true)

在此之后，您将能够从params散列中检索这些值。

ex

params[:名称]

检索字符串'Jason'
