小编Jus*_*yes的帖子

虽然在轨道上乱搞我编码:

<%= form_for :creature, url: "/creatures", method: "post" do |f| %>

  <%= f.text_field :name %>
  <%= f.text_area :description %>
  <%= f.submit "save creature" %>
<% end %>

我清楚地了解这个帖子的位置.但是我发现这也有效:

<%= form_for @creature do |f| %>

  <%= f.text_field :name %>
  <%= f.text_area :description %>
  <%= f.submit "save creature", class: "btn btn-default"%>

<% end %>

我浏览了我的rails应用程序上的文件夹,我知道它仍然发布到此端点'/ creatures'=>'creatures #create'.我想知道第二块代码知道如何仍然发布到该端点.从Node.JS迁移到Rails是有点心灵弯曲.

这是我好奇的控制器:

class CreaturesController < ApplicationController
  def index
    @creatures = Creature.all
  end

  def new
    @creature = Creature.new
  end

  def create
    new_creature = …

每次我调用 validates_with NumberValidator 时。我收到未初始化的常量错误。我在“app”目录下创建了一个名为验证器的目录。这是我到目前为止。

这是我的模型

class Worker < ActiveRecord::Base
    include ActiveModel::Validations
validates_with NumberValidator

end

这是我的验证器文件

class NumberValidator < ActiveModel::Validator
    def validate(record, attribute, value)
        puts record
        puts attribute
        puts value
    end
end
