我有两种模式:用户和教师:
class User < ActiveRecord::Base
attr_accessor :password
attr_accessible :user_login,
:user_role,
:password,
:teacher_attributes
has_one :teacher
accepts_nested_attributes_for :teacher
end
# Table name: teachers
#
# id :integer not null, primary key
# user_id :integer
# teacher_last_name :string(255)
# teacher_first_name :string(255)
# teacher_middle_name :string(255)
# teacher_birthday :date
# teacher_sex :string(255)
# teacher_category :string(255)
# created_at :datetime
# updated_at :datetime
class Teacher < ActiveRecord::Base
attr_accessible :teacher_last_name,
:teacher_first_name,
:teacher_middle_name,
:teacher_birthday,
:teacher_sex,
:teacher_category
belongs_to :user
end
另外,我的控制器中有一个方法,应该创建用户,然后是新老师。但是没有正常工作,因为我没有在那里传递id
。
我的控制器
class AdminsController < ApplicationController
def create_teacher
user_errors, teacher_errors, redirect_path = nil, nil, nil
params[:user][:user_role] = "teacher"
user = User.new(params[:user]) #Problem is here
if user.save
redirect_path = admins_users_of_system_path
flash[:success] = "Teacher created!"
else
redirect_path = admins_new_teacher_path
user_errors = user.errors.full_messages.to_sentence
teacher_errors = user.teacher.errors.full_messages.to_sentence if user.teacher
end
errors_arr = [user_errors, teacher_errors].compact
flash[:error] = errors_arr if errors_arr.present?
redirect_to redirect_path
end
end
我在控制器中有这样的代码,因为我想从用户和老师那里获取所有错误。
错误
["Teacher user can't be blank", "User can't be blank"]

如何正确创建教师和用户?我该怎么把它传给你?
答案 0 :(得分:1)
另一种方法是在第一轮创建用户,包括教师的角色。然后,管理员填写第二个表单,其中包含个人资料详细信息,如果您愿意,请填写“填写您的个人资料”(教师模型仍然包含此内容。)
无论哪种方式,您可能都希望使用delegates_to方法来访问方法http://apidock.com/rails/v3.1.0/Module/delegate
此外,无论你如何做,你可能只考虑将attr_accessible保留,直到其他方式正常工作。
但如果你找到一种方法同时创建它们,我会是第一个复制你的人!

我认为问题是假的,你说错了。 正确的方法应该是: params [:user] ['user_role'] =“老师”
答案 2 :(得分:0)
编辑: 正如我在评论中所说:
尝试:
user = User.create(params[:user])
而不是User.new
