在Rails中，呈现Json如何有条件地重定向

class UsersController < ApplicationController
  def show
    @user = User.find(params[:id])

    respond_to do |format|
      format.html { redirect_to @user }
      format.json { render json: @user }
    end
  end
end

class UsersController < ApplicationController
  def show
    @user = User.find(params[:id])

    respond_to do |format|
      format.html { redirect_to @user }
      format.json do
        if should_redirect_to_json?
          redirect_to some_path
        else
          render json: @user
        end
      end
    end
  end

  private

  def should_redirect_to_json?
    # 根据你的条件逻辑返回true或false
  end
end
