在用户和个人资料之间创建 1:1 关系

Question

我对 RoR 很陌生。

我有两个模型，一个用户（由 Devise 生成）和一个配置文件。

我希望每个用户拥有一个个人资料。

这是我的用户故事：

作为用户，我必须创建个人资料 作为用户，我可以编辑我的个人资料 作为用户，我可以查看所有个人资料

下面，你会看到我的两个不同的模型。

class Profile < ApplicationRecord
 has_attachment :photo
 belongs_to :user, class_name: 'User', foreign_key: :user_id
end

class User < ApplicationRecord
 has_one :profile
 devise :database_authenticatable, :registerable,
 :rememberable, :trackable, :validatable
end

我不知道为什么，但是今天，一个用户可以创建许多个人资料并编辑另一个个人资料。

有人能帮我理解为什么吗？

Answer 1

为了防止用户编辑其他个人资料，您可以在个人资料控制器更新操作中执行类似的操作

if current_user == @profile.user
 allow to edit
else
 don't allow to edit

Answer 2

这是我的 schema.rb

   ActiveRecord::Schema.define(version: 20160510084050) do

这是配置文件控制器

class ProfilesController < ApplicationController

    # if params[:id]
    #   @profiles = Profile.where(handicap: params[:handicap])
    # else
      @profiles = Profile.all
      @hash = Gmaps4rails.build_markers(@profiles) do |profile, marker|
        marker.lat profile.latitude
        marker.lng profile.longitude
      marker.infowindow render_to_string(partial: "/profiles/map_box", locals: { profile: profile })
      end
    end
  end

  def show
    @profile = Profile.find(params[:id])
  end

  def new
    @profile = Profile.new
  end

  def create
    owner = current_user
    @profile = Profile.new(profile_params)
    @profile.owner = owner
    if @profile.save
      redirect_to profiles_path
    else
      render :new
    end
  end

  def edit
  end

  def update
    if @profile.update(profile_params)
      redirect_to profiles_path
    else
      render :edit
    end
  end

  def destroy
  end

  private

  def profile_params
    params.require(:profile).permit(:last_name,:first_name, :address, :search, :handicap, :street, :postbox, :tagline, :skills, :town, :photo)
  end
