Question

我在rails app中安装了cancan gem

我已经阻止了我的能力。这样的人......

can [:action1,:action2,:action3] ,Obj do |x|
  # I wante to get current action, like this
  if action == action1
    #do something
  end
end

我不想将特殊区块中的每个动作分开

如何在能力阻止中获得当前行动？

Answer 1

您可以使用操作作为变量初始化Ability类实例方法：

#models/ability.rb

class Ability
  include CanCan::Ability

  def initialize(user, action)

    can action.to_sym, Obj do |x|
       #do something with your action (and user?)
    end

  end

end

现在您可以初始化新功能，将当前操作传递给它：

#application_controller.rb

def current_ability
  @current_ability ||= Ability.new(current_user, params[:action])
end

并使用存储在默认参数:action

中的操作名称应用任何规则

正是我需要做的！我最终得到了这个解决方案：

<Formik
        initialValues={{}}
        validationSchema={() => Yup.object().shape({`enter your validation keys here`})}
        onSubmit={(values) => {
          console.log('values after submit', values);
        }}
      >
        {(formikProps) => {
          const { values, handleChange } = formikProps;
          return (
            <Form>
              <label>
                name
                <input name="name" onChange={handleChange} />
              </label>
              <label>
                age
                <input name="age" type="number" onChange={handleChange} />
              </label>
              <button
                type="button"
                onClick={() => {
                  console.log('show filled fields', values);
                }}
              >
                Show Filled Fields
              </button>
              <button type={'submit'}> Submit</button>
            </Form>
          );
        }}
      </Formik>
