Question

我刚刚生成了我的用户脚手架，而我现在收到的错误是“密码不能为空”＆＃39;即使我填写了所有的字段。我很困惑，因为我的rake测试正在通过，所以不确定错误在哪里？

用户模型：

class User < ActiveRecord::Base
validates :name, presence: true, uniqueness: true
has_secure_password
end

我的用户控制器：

class UsersController < ApplicationController
 before_action :set_user, only: [:show, :edit, :update, :destroy]

 # GET /users
 # GET /users.json
 def index
  @users = User.order(:name)
 end

 # GET /users/1
 # GET /users/1.json
 def show
 end

 # GET /users/new
def new
 @user = User.new
end

# GET /users/1/edit
def edit
end

# POST /users
# POST /users.json
def create
 @user = User.new(user_params)

respond_to do |format|
  if @user.save
    format.html { redirect_to users_url, notice: "User #{@user.name} 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
end

# PATCH/PUT /users/1
# PATCH/PUT /users/1.json
def update
 respond_to do |format|
  if @user.update(user_params)
    format.html { redirect_to users_url, notice: "User #{@user.name} was successfully updated." }
    format.json { head :no_content }
  else
    format.html { render action: 'edit' }
    format.json { render json: @user.errors, status: :unprocessable_entity }
  end
 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(:name, :password_digest)
end
end

如果您需要提交更多代码，请告诉我们。我正在使用Rails 4。

很高兴在您提交表单时看到server logs，有人告诉我您不需要正确的parameters，从您的表单中应该有：password和{ {1}}但是在控制器中，出于某种原因需要password_confirmation：

password_digest

它应该是：

def user_params
  params.require(:user).permit(:name, :password_digest)
end

和def user_params params.require(:user).permit(:name, :password, :password_confirmation) end不应通过参数更新。
