在Ruby on Rails中獲取加載錯誤3

Question

您好，我使用Rails3製作一個表單時出現以下錯誤。

錯誤：

LoadError in SdfsController#edit 

Expected C:/Site/swargadwar_admin/app/models/t_sdf.rb to define T_sdf 
Rails.root: C:/Site/swargadwar_admin 

Application Trace | Framework Trace | Full Trace 
app/controllers/sdfs_controller.rb:6:in `edit' 

第二個錯誤：

ActiveRecord::StatementInvalid in SdfsController#create 

Mysql::Error: Out of range value for column 'Donation_Amount' at row 1: INSERT INTO `t_sdfs` (`Brahmin`, `Created_By`, `Date_Of_Death`, `Deceased_Address1`, `Deceased_Address2`, `Deceased_Block`, `Deceased_Country`, `Deceased_Dist`, `Deceased_Name`, `Deceased_PS`, `Deceased_State`, `Deceased_Village`, `Donation_Amount`, `Donation_Date`, `Doner_Address1`, `Doner_Address2`, `Doner_Block`, `Doner_Country`, `Doner_Dist`, `Doner_MobileNo`, `Doner_Name`, `Doner_PS`, `Doner_Photo`, `Doner_Relationship_ID`, `Doner_Relationship_Other`, `Doner_State`, `Doner_Thumb`, `Doner_Video`, `Doner_Village`, `HCSY_Status`, `Photo`, `Updated_By`, `created_at`, `receipt_no`, `updated_at`) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?) 
Rails.root: C:/Site/swargadwar_admin

我解釋我下面的代碼，請檢查這些，讓我知道它將如何解決。

模型/ t_sdf.rb

class TSdf < ActiveRecord::Base 
     attr_accessible :Brahmin, :Created_By, :Date_Of_Death, :Deceased_Address1, :Deceased_Address2, :Deceased_Block, :Deceased_Country, :Deceased_Dist, :Deceased_Name, :Deceased_PS, :Deceased_State, :Deceased_Village, :Donation_Amount, :Donation_Date, :Doner_Address1, :Doner_Address2, :Doner_Block, :Doner_Country, :Doner_Dist, :Doner_MobileNo, :Doner_Name, :Doner_PS, :Doner_Photo, :Doner_Relationship_ID, :Doner_Relationship_Other, :Doner_State, :Doner_Thumb, :Doner_Video, :Doner_Village, :HCSY_Status, :Photo, :Updated_By, :receipt_no 
    mount_uploader :Photo, PhotoUploader 
    mount_uploader :Doner_Photo, DonerPhotoUploader 
    end 

控制器/ sdfs_controller.rb

class SdfsController < ApplicationController 
    def new 

    end 
    def edit 
     @sdf=T_sdf.new 
    end 
    def create 
     @sdf=T_sdf.new(params[:sdf]) 
     if @sdf.save 
      flash[:notice]="Data saved successfully" 
      flash[:color]="valid" 
      redirect_to :action => 'new', :controller => "admins" 
     else 
      flash[:alert]="Data could not saved" 
      flash[:color]="invalid" 
      render 'edit' 
     end 
    end 
end

在您的控制器中，將該類名稱T_sdf更改爲TSdf。

def edit 
    @sdf=TSdf.new 
end
