Question

我有一个用户模型和一个user_details模型。 User_details只包含有关用户的更多详细信息。

我正在尝试创建一个页面，其中有人可以在一个页面上为该用户编辑用户和user_details，但由于我的users表中有1行，而user_details表中没有行，因此没有文本字段显示在我的编辑页面上。

如果user_details表中没有数据，如何让user_details的文本字段显示在我的编辑页面上？

我的contacts_controller的一部分：

# GET /contacts/1/edit
    # shows a users profile in edit mode
    def edit
        @userProfile = User.find(params[:id])
        @userProfile.build_user_details
        #@userProfile.user_details.build
        #question.answers.build
        respond_to do |format|
            format.html 
        end
    end

    # POST /contacts/1/edit
    # actually updates the users data
    def update_user

        @userProfile = User.find(params[:id])

        respond_to do |format|

            if @userProfile.update_attributes(params[:user])

                format.html {
                    flash[:success] = "Information updated successfully"
                    render :edit
                }
            else 

                format.html {
                    flash[:error] = resource.errors.full_messages

                    render :edit
                }
            end
        end
    end

用户模型

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :token_authenticatable, :encryptable, :confirmable, :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable, :authentication_keys => [:login]

  # Virtual attribute for authenticating by either username or email
  # This is in addition to a real persisted field like 'username'
  attr_accessor :login

  # Setup accessible (or protected) attributes for your model
  attr_accessible :email, :password, :password_confirmation, :remember_me, :username, :login, :first_name, :last_name, :home_phone, :cell_phone, :work_phone, :birthday, :home_address, :work_address, :position, :company, :user_details

  has_one :user_details, :dependent => :destroy
  accepts_nested_attributes_for :user_details

  # validates email or username when logging in
  def self.find_first_by_auth_conditions(warden_conditions)
    conditions = warden_conditions.dup
    if login = conditions.delete(:login)
      where(conditions).where(["lower(username) = :value OR lower(email) = :value", { :value => login.downcase }]).first
    else
      where(conditions).first
    end
  end

end

User_details模型

class UserDetails < ActiveRecord::Base
  belongs_to :user
end

edit.html.erb

Answer 1

您使用了错误的关联名称：

has_one :user_detail，而不是has_one :user_details,

@userProfile.build_user_detail，而不是@userProfile.build_user_details

编辑和更新操作时，您的http方法为put，而不是post，因此请更改此信息：

<%= form_for(@userProfile, :url => {:controller => "my_devise/contacts", :action => "update_user"}, :html => {:class => "form grid_6"}, :method => :post ) do |f| %>

对此：

<%= form_for(@userProfile, :url => {:controller => "contacts", :action => "update_user"}, :html => {:class => "form grid_6"}, :method => :put ) do |f| %>

尝试重新编辑和更新。

但我更喜欢将update_user操作重命名为update，它会遵循rails的惯例，制作适合您的编辑和操作。更新更容易。如果您要编辑和更新联系人的路线如下：

edit_contact GET    /contacts/:id/edit(.:format)  contacts#edit
     contact PUT    /contacts/:id(.:format)        contacts#update

您只需要定义表单：

<%= form_for(@userProfile, :html => {:class => "form grid_6"}) do |f| %>

我认为您还需要向联系人控制器添加new和create操作，因此表单会知道用户是否还没有user profile，它会创建新的而不是更新。< / p>

Answer 2

我终于想通了整个时间，我错过了=。

我改变了

<% f.fields_for :user_details do |d| %>

到

<%= f.fields_for :user_details do |d| %>

他们都在那里。
