推荐答案

添加这样的关联

对于产品

FactoryBot.define do 
    factory :product do
      user {User.first || association(:user)}
      user {User.first || association(:user, admin: true)}
      # your admin attribute (role: admin or admin: true) whatever you are using for admin
      category {Category.first || association(:category)}
    end
end
