在rails redirect_to中传递参数

Question

我们如何在rails的redirect_to中传递参数？我知道我们可以使用以下方式传递ID：redirect_to :action => action_name,:id => 3如果我想传递其他参数（例如某些表单数据）怎么实现呢？编辑：对于Ruby 2语法，您必须将上面的代码段更新为：redirect_to action: action_name, id: 3

Answer 1

只需将它们附加到选项：

redirect_to controller: 'thing', action: 'edit', id: 3, something: 'else'

会屈服 /thing/3/edit?something=else

Answer 2

如果您正在使用RESTful资源，则可以执行以下操作：

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')

您可以使用flash参数将任意对象传递到模板。

 redirect_to :back, flash: {new_solution_errors: solution.errors}

然后通过哈希在模板中访问它们。

<% flash[:new_solution_errors].each do |err| %>
