Question

我在初级网络应用程序上工作，使用简单的表格来保存用户的日期请求。

这是代码

视图/天/ index.html.erb

  <%= form_for @daysoff, url: {action: "create"} do |f| %>
  <%= f.date_field :offdate, id: 'altField' %>
  <p> User holding the fort / Yerine bakicak kisi

    <%= f.collection_select(:assign_id, @people, :id, :name) %> </p>
    <%= f.hidden_field :user_id, value: @user.id %>
    <%= f.submit "Submit" %>
    <% end %>

控制器/ days_controller.rb

class DaysController < ApplicationController
  unloadable

    def index
    @people = User.all
    @user = User.current

    @daysoff = Daysoff.new

#    params[:daysoff][:user_id] = @user.id

  end

  def create

    off_dates = params["daysoff"]["offdate"].try(:split,',')

    off_dates.each do |off_date|
      @days_off = Daysoff.new
      @days_off.offdate = Date.strptime(off_date.strip, "%m/%d/%Y")
      @days_off.user_id = User.current
      @days_off.assign_id = params["assign_id"]
      @days_off.status = 0
      @days_off.save!
    end

    redirect_to "/days_off_redmine", :flash => { :success => "Istek gonderildi." }

  end

没有任何模型验证。

数据库迁移文件。

class CreateDaysoffs < ActiveRecord::Migration
  def change
    create_table :daysoffs do |t|
      t.date :offdate
      t.integer :user_id
      t.integer :assign_id
      t.boolean :status
    end
  end
end

当我尝试填写并发布表格时，正确填写了过期和状态，但user_id和assign_id将db插入为NULL。

+----+------------+---------+-----------+--------+
| id | offdate    | user_id | assign_id | status |
+----+------------+---------+-----------+--------+
|  1 | 2015-07-14 |    NULL |      NULL |      0 |
|  2 | 2015-07-15 |    NULL |      NULL |      0 |
|  3 | 2015-07-14 |    NULL |      NULL |      0 |
|  4 | 2015-07-15 |    NULL |      NULL |      0 |
|  5 | 2015-07-22 |    NULL |      NULL |      0 |
|  6 | 2015-07-23 |    NULL |      NULL |      0 |
|  7 | 2015-07-21 |    NULL |      NULL |      0 |
|  8 | 2015-07-22 |    NULL |      NULL |      0 |
|  9 | 2015-07-21 |    NULL |      NULL |      0 |
| 10 | 2015-07-22 |    NULL |      NULL |      0 |
| 11 | 2015-07-21 |    NULL |      NULL |      0 |
| 12 | 2015-07-22 |    NULL |      NULL |      0 |
| 13 | 2015-07-29 |    NULL |      NULL |      0 |
| 14 | 2015-07-30 |    NULL |      NULL |      0 |
| 15 | 2015-07-29 |    NULL |      NULL |      0 |
| 16 | 2015-07-30 |    NULL |      NULL |      0 |

为什么会出现这种情况？

Answer 1

省略代码看起来很糟糕的事实......

表单属性出现在params[:daysoff]中，您需要通过它来访问字段，例如：

通过params[:daysoff][:assign_id]

获取assign_id

@days_off.user_id = User.current应该是：@days_off.user_id = User.current.id

或@days_off应该在模型类中添加

belongs_to :user并且它会正常工作，除非User.current是nil

Rails POST表单不要向数据库发送完整的数据
