[英] Rails 6: Only one profile per user should be created
本文介绍了Rails 6:每个用户只能创建一个配置文件的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我目前正在开发一个 Rails 6 应用程序.我有以下关联.一个用户有一个配置文件，一个配置文件属于一个用户.在为用户编辑配置文件时，我最终为该用户创建了两个配置文件.我希望每个用户只有一个个人资料.
编辑表单:profile/edit.html.erb
<%= form_for @profile do |f|％＞<div class="form-group"><%= f.label :avatar %><%= f.file_field :avatar, as: :file, class: "form-control" %>
<div class="form-group"><%= f.label :full_name, '全名' %><%= f.text_field :full_name, autofocus: true, class: "form-control" %>
<div class="form-group"><%= f.label :city, 'City' %><%= f.text_field :city, class: "form-control" %>
<div class="form-group"><%= f.label :bio, 'Bio'%><p>你为什么加入ArtsySpace?这里的其他人应该了解你什么?</p><%= f.text_field :bio, class: "form-control"%>
<div class="form-group"><%= f.submit "Edit profile", class: "btn btn-primary" %>
<%结束%>
我从控制台看到用户 1 有 2 个配置文件.我不确定配置文件是如何创建的，也许我从配置文件控制器点击了 create 方法但出错了，但我希望这不会发生.是否只验证一个个人资料属于用户?
class ProfilesController <应用控制器定义新@profile = current_user.build_profile结尾定义创建@profile = current_user.create_profile(profile_params)@profile.avatar.attach(params[:profile][:avatar])如果@profile.save重定向到@post别的呈现新"结尾结尾高清秀@profile = Profile.find(params[:id])结尾定义编辑@profile = current_user.profile结尾定义更新@profile = current_user.profile如果@profile.update!(profile_params)redirect_to @profile，注意:'配置文件已成功更新.'别的渲染:编辑结尾结尾定义删除@profile = current_user.profile.find(params[:id])@profile.destroy结尾私人的def profile_paramsparams.require(:profile).permit(:full_name, :city, :bio, :avatar)结尾结尾
我不确定问题是否来自配置路由的方式?
Rails.application.routes.draw 做设计为:用户devise_scope : 用户做资源 :profiles, only: [:edit, :update]结尾资源 :profiles, only: [:show]资源:帖子做资源:评论，仅:%i[显示新创建编辑更新]结尾结尾类用户<申请记录# 包括默认设计模块.其他可用的有:# :confirmable, :lockable, :timeoutable, :trackable 和 :omniauthable设计 :database_authenticable, :registerable,:recoverable, :rememberable, :validatablehas_many : 帖子has_one :个人资料accepts_nested_attributes_for :profile结尾
从下面的代码片段中，您可以看到用户有 2 个 user_id 的个人资料:1
[#<Profile id: 3, user_id: 1, full_name: "steven ", city: "diego ", bio: "Because im ", created_at: "2019-06-12 23:11:49", updated_at: "2019-06-16 18:49:22">, #]
不确定问题出在哪里.
解决方案
我曾经通过这样做解决了这个问题(我知道这很奇怪，我只是把它作为一个想法放在这里)
has_one :profilehas_many :个人资料验证 :profiles, 长度: { in: 0..1 }
https://guides.rubyonrails.org/active_record_validations.html#length
I'm currently working on a Rails 6 application. I have the following association. A User has a Profile and a Profile belongs to a User. When editing a profile for a user I ended up having two profiles for the user. I would like to have only one profile per user.
Edit form: profile/edit.html.erb
<%= form_for @profile do |f| %>
<div class="form-group">
<%= f.label :avatar %>
<%= f.file_field :avatar, as: :file, class: "form-control" %>
</div>
<div class="form-group">
<%= f.label :full_name, 'Full Name' %>
<%= f.text_field :full_name, autofocus: true, class: "form-control" %>
</div>
<div class="form-group">
<%= f.label :city, 'City' %>
<%= f.text_field :city, class: "form-control" %>
</div>
<div class="form-group">
<%= f.label :bio, 'Bio'%>
<p> Why did you join ArtsySpace?
What should other people here know about you?
</p>
<%= f.text_field :bio, class: "form-control"%>
</div>
<div class="form-group">
<%= f.submit "Edit profile", class: "btn btn-primary" %>
</div>
<% end %>
I see from the console that user 1 has 2 profiles. I'm not sure how a profile was created maybe I hit the create method from profile controller but mistake but I would like for this not to happen. Is there a validation for only one profile to belong to user?
class ProfilesController < ApplicationController
def new
@profile = current_user.build_profile
end
def create
@profile = current_user.create_profile(profile_params)
@profile.avatar.attach(params[:profile][:avatar])
if @profile.save
redirect_to @post
else
render 'new'
end
end
def show
@profile = Profile.find(params[:id])
end
def edit
@profile = current_user.profile
end
def update
@profile = current_user.profile
if @profile.update!(profile_params)
redirect_to @profile, notice: 'Profile was successfully updated.'
else
render :edit
end
end
def delete
@profile = current_user.profile.find(params[:id])
@profile.destroy
end
private
def profile_params
params.require(:profile).permit(:full_name, :city, :bio, :avatar)
end
end
I'm not sure if the issue comes from the way the routes are configured?
Rails.application.routes.draw do
devise_for :users
devise_scope :users do
resources :profiles, only: [:edit, :update]
end
resources :profiles, only: [:show]
resources :posts do
resource :comments, only: %i[show new create edit update]
end
end
class User < ApplicationRecord
# Include default devise modules. Others available are:
# :confirmable, :lockable, :timeoutable, :trackable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :validatable
has_many :posts
has_one :profile
accepts_nested_attributes_for :profile
end
From the below snippet you can see that a user has 2 profiles for user_id: 1
[#<Profile id: 3, user_id: 1, full_name: "steven ", city: "diego ", bio: "Because im ", created_at: "2019-06-12 23:11:49", updated_at: "2019-06-16 18:49:22">, #<Profile id: 4, user_id: 1, full_name: "andrew", city: "Tony", bio: "because i know ", created_at: "2019-06-12 23:12:35", updated_at: "2019-06-16 18:51:22">]
Not sure where the issue came from.
解决方案
I once solved this by doing (I know it's strange, I'm just putting it out here as an idea)
has_one :profile
has_many :profiles
validates :profiles, length: { in: 0..1 }
