我有用户和个人资料模型。我为用户和个人资料创建了一个表单。当任何人输入详细信息时，只有用户的详细信息才会保存在数据库中而不是配置文件中。
用户模型
class User < ApplicationRecord has_many :comments
has_many :repositories
has_many :searches
has_many :issues
has_many :feedbacks
has_one :profile
#-------------------------- VALIDATIONS-----------------------------------------#
EMAIL_REGEX = /\A([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})\z/i
validates :username, :presence => true, :uniqueness => true, :length => { :in => 3..20 }
validates :email, :presence => true, :uniqueness => true, :format => EMAIL_REGEX
validates :password, :confirmation => true #password_confirmation attr
validates_length_of :password, :in => 6..20, :on => :create
#-------------------------- ENCRYPTION-----------------------------------------#
before_save :encrypt_password, :default_values
after_save :clear_password
def encrypt_password
if password.present?
self.salt = BCrypt::Engine.generate_salt
self.encrypted_password= BCrypt::Engine.hash_secret(password, salt)
end
end
def clear_password
self.password = nil
end
#-------------------------- AUTHENTICATION-----------------------------------------#
def self.authenticate(username_or_email="", login_password="")
if EMAIL_REGEX.match(username_or_email)
user = User.find_by_email(username_or_email)
else
user = User.find_by_username(username_or_email)
end
if user && user.match_password(login_password)
return user
else
return false
end
end
def match_password(login_password="")
encrypted_password == BCrypt::Engine.hash_secret(login_password, salt)
end
private
def default_values
type ||= false
end
end
个人资料模型
class Profile < ApplicationRecord
before_save :default_values
belongs_to :user
validates :fname, :presence=> true
validates :lname, :presence=> true
validates :city, :presence=> true
validates :state, :presence=> true
validates :country, :presence=> true
validates :zip_code, :presence=> true
validates :phone_no, :presence=> true
private
def default_values
followers ||= 0
following ||= 0
end
end
用户控制器
class UsersController < ApplicationController
before_filter :save_login_state, :only => [:new, :create]
def new
@user = User.new
@profile = Profile.new
end
def create
@user = User.new(user_params)
@profile = Profile.new(profile_params)
if @user.save
@profile.save
flash.now[:notice] = "Signed up successfully !!"
@users = User.all # to get all users in @users
@profiles = Profile.all # to get profile of all users in @profiles
render "show" # display show.html.erb while passing @users and @profiles ?
else
flash.now[:notice] = "Invalid form"
flash.now[:color] = "Invalid"
redirect_to :root
end
end
def show
@users = User.all # same as above. not working if removed from above.
@profiles = Profile.all # same as above. not working if removed from above.
end
def edit
user = @current_user
profile = user.profile
end
private
def user_params
params.require(:user).permit(:username, :email, :password)
end
def profile_params
params.require(:profile).permit(:fname, :lname, :dob, :city, :state, :country, :zip_code ,:phone_no)
end
end

您可以使用更简单的内容，在用户模型上添加此行
document.getElementById("datatable1").style.display = "block" //Show the table
document.getElementById("datatable2").style.display = "none"; //Hide the table
function handleClick(myRadio) {
if (myRadio.value == "table2"){
document.getElementById("datatable1").style.display = "none";
document.getElementById("datatable2").style.display = "block" ;
}
else{
document.getElementById("datatable1").style.display = "block" ;
document.getElementById("datatable2").style.display = "none";
}
}
然后如果params具有正确的结构，则在创建用户时，也会添加配置文件。只记得在控制器中添加许可证上的参数
def user_params params.require（：user）.permit（：username，：email，：password， profile_attributes：[：id，：attribute1，：attribute2]） 端
在您的创建操作上，您只需添加此
accepts_nested_attributes_for :profile, reject_if: :all_blank, allow_destroy: true
以这种方式，将创建用户和个人资料，如果其中任何一个出现错误，使用验证，将不会保存任何内容，并且您不必担心删除用户该档案未被保存。
