How do we pass parameters in redirect_to in rails? I know we can pass id using this:
我们如何在rails中的redirect_to中传递参数？我知道我们可以使用这个传递 id：

For Ruby 2 syntax you have to update the snippet above to:
对于 Ruby 2 语法，您必须将上面的代码段更新为：

Just append them to the options:
只需将它们附加到选项：
redirect_to controller: 'thing', action: 'edit', id: 3, something: 'else'
Would yield /thing/3/edit?something=else
会屈服 /thing/3/edit?something=else

If you are using RESTful resources you can do the following:
如果您使用 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')

If you have some form data for example sent to home#action, now you want to redirect them to house#act while keeping the parameters, you can do this
如果您有一些表单数据，例如发送到 home#action，现在您想将它们重定向到 house#act，同时保留参数，您可以这样做
redirect_to act_house_path(request.parameters)
redirect_to act_house_path(request.parameters)

You can pass arbitrary objects to the template with the flash parameter.
您可以使用 flash 参数将任意对象传递给模板。
redirect_to :back, flash: {new_solution_errors: solution.errors}
And then access them in the template via the hash.
然后通过哈希在模板中访问它们。
<% flash[:new_solution_errors].each do |err| %>

If you are looking for a way to pass additional URL parameters (not controller, action, id, etc), here's a robust method for doing so:
如果您正在寻找一种传递额外 URL 参数（不是控制器、操作、id 等）的方法，这里有一个强大的方法：
object_path(@object, params: request.query_parameters)
That will pass along utm parametersor any other additional params you don't want to lose.
这将传递utm 参数或您不想丢失的任何其他附加参数。

Route your path, and take the params, and return:
路由你的路径，然后走params，然后返回：
redirect_to controller: "client", action: "get_name", params: request.query_parameters and return
