儲蓄記錄從進口積極記錄

Question

我最近添加了一個導入選項，我的RoR項目似乎正在上傳文件，並將此文件成功存儲到數據庫，但是當它試圖創建新用戶並保存它們時正在以下錯誤

Started GET "/imports/13/proc" for 127.0.0.1 at 2012-07-11 02:52:00 +1000

這是代碼我在我的進口控制器

def new_user(line) 
    params = Hash.new 
    params[:user] = Hash.new 
    params[:user]["email"] = line[0] 
    params[:user]["gender"] = "male" 
    params[:user]["password"] = "abc231" 
    params[:user]["first_name"] = line[1] 
    params[:user]["last_name"] = line[3] 
    user = User.new(params[:user]) 
    user.save 
    end 


def proc_csv 
    @import = Import.find(params[:id]) 
    lines = parse_csv_file(@import.csv.path) 
    lines.shift #comment this line out if your CSV file doesn't contain a header row 
    if lines.size > 0 
     @import.processed = lines.size 
     lines.each do |line| 
     case @import.datatype 
      when "releases" 
      new_user(line) 
      flash[:notice] = "Saving data processing was successful." 
     end 
     end 
     @import.save 
     flash[:notice] = "CSV data processing was successful." 
     redirect_to :action => "show", :id => @import.id 
    else 
     flash[:error] = "CSV data processing failed." 
     render :action => "show", :id => @import.id 
    end 
    end

    def parse_csv_file(path_to_csv) 
    lines = [] 

    #if not installed run, sudo gem install fastercsv

    require 'csv' 

    CSV.foreach(path_to_csv) do |row| 
     lines << row

Answer 1

從您的代碼片段和日誌輸出看來，您的用戶似乎沒有被保存，因爲一些驗證問題。 通常當我遇到這樣的問題時，我只需下載到rails控制檯，並找出 ，如果我的代碼試圖在控制檯中工作。如果它在控制檯上工作，那麼你的代碼應該工作。

試試這個

$ rails c --sandbox 

> params = { 
      :user => { 
        :gender => "male", 
       :last_name => "paul", 
       :password => "abc231", 
       :first_name => "mcguane", 
        :email => "paul.mcguane1@westnet.com.au" 
      } 
     } 

> user = User.new(params[:user]) 
> user.valid? 
> user.errors.full_messages 

這樣一來，你就可以隔離如果真的用戶驗證問題的原因。它可能完全是另一回事。如果你發佈你的用戶模型代碼也會有所幫助。

我還注意到你在lines迭代器中設置了一個flash通知。每次迭代一行時，都只是簡單地覆蓋它。
