Ruby on rails Rails-销毁用户组中的成员资格/所有权

如果用户是组的所有者，则在“销毁”组的成员身份时，我需要能够“销毁”组所有权。我有“用户”、“组/Cliq”和“组/CliqMembership”模型。当用户创建组时，他们是组的“所有者”。然后，其他用户可以加入该组。当用户离开组时，该用户和组的成员关联将被销毁。但是，当所有者离开组时，它只删除“成员资格”，而不删除“所有权”。我觉得应该有一个简单的解决办法，但我有点卡住了

为清楚起见：Cliqs=组；问题是：如何同时删除所有权协会和会员协会？当一个“所有者”离开一个组时，我希望它摧毁他们的“组所有权”和“组成员资格”。旁白：当“所有者”离开时，我将如何使所拥有的组“摧毁依赖性”

以下是我的模型：

class Cliq < ActiveRecord::Base
 belongs_to :owner, class_name: 'User'

 has_many :cliq_memberships
 has_many :members, through: :cliq_memberships, source: :user

end

class CliqMembership < ActiveRecord::Base
 belongs_to :cliq
 belongs_to :user
end

class User < ActiveRecord::Base
 has_one :owned_cliq, foreign_key: 'owner_id', class_name: 'Cliq', dependent: :destroy

 has_many :cliq_memberships
 has_many :cliqs, through: :cliq_memberships
 .
 .
 .
end

类Cliq 和我的控制器：

class CliqsController < ApplicationController

def show
    @cliq = Cliq.find(params[:id])
end

def new
    @cliq = Cliq.new(params[:id])
end

def create
    @cliq = current_user.build_owned_cliq(cliq_params)
    @cliq.members << current_user

    if @cliq.save
        redirect_to current_user
    else
        redirect_to new_cliq_path
    end
end

def destroy
    @cliq = current_user.owned_cliq.find(params[:id])
    flash[:alert] = "Are you sure you want to delete your Cliq? Your Cliq and all of its associations will be permanently deleted."
    @cliq.destroy

    if @cliq.destroy
       redirect_to current_user
       flash[:notice] = "You deleted the Cliq."
    else
        redirect_to current_user
        #set up error handler
        flash[:notice] = "Failed to delete Cliq."
    end
end


def cliq_params
    params.require(:cliq).permit(:name, :cliq_id)
end

class CliqMembershipsController < ApplicationController

def show
end

def create
    #Cliq or Cliq_ID?
    @cliq = Cliq.find(params[:cliq])

    @cliq_membership = current_user.cliq_memberships.build(cliq: @cliq)
    @cliq.members << current_user

    if @cliq_membership.save
        flash[:notice] = "Joined #{@cliq.name}"
    else
        #Set up multiple error message handler for rejections/already a member
        flash[:notice] = "Not able to join Cliq."
    end
    redirect_to cliq_url
end

def destroy
    @cliq_membership = current_user.cliq_memberships.find(params[:id])
    @cliq_membership.destroy

    if @cliq_membership.destroy
       flash[:notice] = "You left the Cliq."
    redirect_to user_path(current_user)

    else
    end
    end
end

class UsersController < ApplicationController

def show 
@user = User.find(params[:id])
@uploads = Upload.all
@cliq_memberships = CliqMembership.all
@cliqs = Cliq.all
end

end

class CliqsController@cliq.members在您的CliqMemberships控制器的销毁操作中，在销毁CliqMembership之前，您可以检查当前用户对组的所有权，就像检查他/她的成员资格一样。我假设您想要一个实现，其中如果所有者离开组，您也希望组及其所有成员身份自动被销毁。（如果我错了，请纠正我。）在这种情况下，您可以将
dependent:：destroy
添加到
has\u many:cliq\u成员身份

如果当前用户恰好是所有者，您可以完全销毁cliq，这反过来也会破坏其cliq\U成员身份

您可以在CliqMemershipsController的销毁操作中这样做

def destroy
    @cliq_membership = current_user.cliq_memberships.find(params[:id])
    @cliq = @cliq_membership.cliq
    if @cliq.owner == current_user
        @cliq.destroy
        flash[:notice] = "The Cliq is destroyed"
        redirect_to user_path(current_user)
    else
        # destroy only the membership
        flash[:notice] = "You left the Cliq."
        redirect_to user_path(current_user)
    end
end

我知道我错过了最后一块。这很有魅力！谢谢！
