Rails: User.Create 通过参数失败

Question

用户控制器

当从我的表单提交这个时，它只是 return 到 return 页面的注册，因为 .save 总是失败。

 def show
    @user = User.find(params[:id])
 end
 def new
     @user = User.new
 end

 def create
    @user = User.new user_params
    if @user.save
         redirect_to @user
    else
        render 'new'
    end
end

    def user_params
        params.require(:user).permit(:username, :email, :password, :password_confirmation)
    end
end

我试过了，但我得到了 ActiveModel::ForbiddenAttributesError

def create
@user = User.new(params[:user])
if @user.save
redirect_to @user
else
render 'new'
end
end

Schema.rb

 ActiveRecord::Schema.define(version: 20150215194936) do

  create_table "users", force: :cascade do |t|
    t.string   "name"
    t.string   "email"
    t.datetime "created_at",      null: false
    t.datetime "updated_at",      null: false
    t.string   "password_digest"
  end

  add_index "users", ["email"], name: "index_users_on_email", unique: true

end

你应该修改这一行：

params.require(:user)
      .permit(:name, :email, :password, :password_confirmation)

您的模型具有字段 :name，但您使用的是 :username。
