在我的 Rails 应用程序上安装 Bcrypt 后，即使填写了表单，也会出现验证问题：password=>“Can't be blank”：
这是我的用户模型
class User < ActiveRecord::Base
before_save { self.email = email.downcase }
validates :username, presence: true, length: { maximum: 50 }
VALID_EMAIL_REGEX = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i
validates :email, presence: true,
format: { with: VALID_EMAIL_REGEX },
uniqueness: { case_sensitive: false }
has_secure_password
validates :password, length: { minimum: 6 }
end
我已经在 rails c 中尝试过，现在出现了摘要：
用户创建：
User.create(username: "Riprova", email:"testato@gmail.com", password: "nonfunzia", password_confirmation:"nonfunzia")
<User id: 15, username: "Riprova", name: nil, surname: nil, email: "testato@gmail.com", gender: nil, birth: nil, created_at: "2013-08-11 15:35:03", updated_at: "2013-08-11 15:35:03", password_digest: "$2a$10$Q/5qtZYDXRcFsUWgve3JL.wui4hSHLhGgsuO0C6TTkBY...">
用户控制器：
class UsersController < ApplicationController
before_action :set_user, only: [:show, :edit, :update, :destroy]
# GET /users

@users = User.all

end

def new
@user = User.new

# POST /users.json
def create
@user = User.new(user_params)
respond_to do |format|
if @user.save
format.html { redirect_to @user, notice: 'User was successfully created.' }
format.json { render action: 'show', status: :created, location: @user }
else
format.html { render action: 'new' }
format.json { render json: @user.errors, status: :unprocessable_entity }
end

end

def update
respond_to do |format|

format.html { redirect_to @user, notice: 'User was successfully updated.' }
format.json { head :no_content }

end
end
# DELETE /users/1
# DELETE /users/1.json
def destroy
@user.destroy
respond_to do |format|
format.html { redirect_to users_url }
format.json { head :no_content }
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_user
@user = User.find(params[:id])
end
# Never trust parameters from the scary internet, only allow the white list through.
def user_params
params.require(:user).permit(:username, :name, :surname, :email, :bids_left, :bids_left_free, :gender, :birth)
end
end
