我是Rails的新手,这里是我目前的情况:我有一个他们所属的用户和团队的联合表,所有团队都有一个名为organization_id的属性,我想确保我可以' •将一个用户添加到表中,以便表中存在具有相同用户的现有条目,并且它具有与新条目相同的organization_id,即如果我有条目(michael,team_rupert)和team_rupert的organization_id是1,我可以再增加一个条目(迈克尔,team_andrew),其中team_andrew的的organization_ID也为1。这里是我的导师,我张罗为自定义的测试,但它似乎没有工作Rails联合表自定义验证
class Membership < ApplicationRecord
belongs_to :user
belongs_to :team
validate :user_can_only_be_in_one_team_per_organization
validates_uniqueness_of :user_id, scope: :team_id
def user_can_only_be_in_one_team_per_organization
organizations = self.user.organizations
organization_ids = organizations.pluck :id
unique_organization_ids = organization_ids.uniq
if organization_ids.count != unique_organization_ids.count
errors.add :user, 'can\'t be in two teams in the same organization'
end
end
end
class User < ApplicationRecord
has_many :memberships
has_many :answers, dependent: :destroy
has_many :teams, through: :memberships
has_many :organizations, through: :teams
validates :username, presence: true,
uniqueness: true
end
class Organization < ApplicationRecord
has_many :teams
has_many :memberships, through: :teams
has_many :users, through: :memberships
validates :name, presence: true,
uniqueness: true
end
class Team < ApplicationRecord
has_many :memberships
has_many :users, through: :memberships
belongs_to :organization
validates :name, presence: true,
uniqueness: true
end
预先感谢你的帮助。
编辑:我设法解决它,结果是新的值还没有添加到表中,所以if语句应该检查我们当前的organization_id是否在organization_id数组中。
我很困惑。如果rupert团队的organization_id为1,team andrew的组织ID将不会为1.您的意思是您想避免连接表中的重复项? –

组织可以有许多团队,团队可以有很多用户,对不起,忘了提到这一点。 – Robert
