乍一看,这个问题似乎已经得到了回答,但不是我的情况(大部分都与质量分配问题和/或mongoid有关。)即使有很多问题,我还是找不到答案。相关问题在这里。
所以基本上我在ruby on rails应用程序上使用devise gem进行用户身份验证,我想在用户模型中添加嵌套地址模型。我还使用simple_form生成表单视图。
我有一个用户模型:
class User < ActiveRecord::Base
has_and_belongs_to_many :roles
has_one :address
accepts_nested_attributes_for :address, :allow_destroy => true
end
这是地址模型:
class Address < ActiveRecord::Base
belongs_to :country
belongs_to :state
belongs_to :user
attr_accessible :street1, :street2, :country_id, :state_id, :city, :postalCode
end
这是Users控制器,我为了添加show动作来显示用户配置文件而覆盖。
class Users::RegistrationsController < Devise::RegistrationsController
def new
resource = build_resource({})
resource.build_address
respond_with resource
end
# POST /resource
def create
resource = build_resource(params[:user])
if resource.save
if resource.active_for_authentication?
set_flash_message :notice, :signed_up if is_navigational_format?
sign_up(resource_name, resource)
respond_with resource, :location => after_sign_up_path_for(resource)
else
set_flash_message :notice, :"signed_up_but_#{resource.inactive_message}" if is_navigational_format?
expire_session_data_after_sign_in!
respond_with resource, :location => after_inactive_sign_up_path_for(resource)
end
else
clean_up_passwords resource
respond_with resource
end
end
def show
@user = User.find(params[:id])
#Add to view count if not viewing own user profile
if @user != current_user
@user.views += 1
@user.save
end
@vehicles = Vehicle.where(:user_id => @user)
respond_to do |format|
format.html # show.html.erb
format.json { render json: @user }
end
end
end
这是创建新用户的视图:
<%= simple_form_for(resource, :as => resource_name, :url => registration_path(resource_name) ) do |f| %>
<fieldset>
<%= f.input :username, :required => false, :autofocus => true, placeholder: 'Pick a username' %>
<%= f.input :email, :required => false, placeholder: 'Your email' %>
<%= f.input :password, :required => false, placeholder: 'Create a password' %>
<%= f.input :password_confirmation, :required => false, placeholder: 'Confirm your password' %>
<%= f.association :roles, :as => :check_boxes, :label => "", :required => false %>
<%= f.simple_fields_for :address do |a| %>
<%= a.input :street1 %>
<%= a.input :street2 %>
<%= a.association :country %>
<%= a.association :state %>
<%= a.input :city %>
<%= a.input :postalCode %>
<% end %>
<%= f.button :submit, 'Sign up for free', :class => 'btn btn-success btn-large' %>
</fieldset>
<% end %>
因此创建新用户时的错误是: 地址用户不能为空
基本上没有为地址设置外键user_id。
我希望有人能对这个问题有所了解。

我能够在我的应用程序中解决这个问题,但我使用的是强参数。但是,解决方案仍应适用于您的情况。
而不是覆盖RegistrationsController
中的所有方法,我只是覆盖build_resource
以传递所需的正确参数。
def build_resource(params)
super(resource_params)
end
def resource_params
params.require(:user).permit(:email, :password, tickets_attributes: [ :description ] )
end
我的inverse_of
和User
模型上也有Ticket
,就像这样:
user.rb
has_many :tickets, inverse_of: :user
ticket.rb
belongs_to :user, inverse_of :tickets
答案 1 :(得分:0)
忘记添加user_id以进行地址迁移。在将belongs_to:user添加到地址模型时,Rails期望它。
