好吧,所以我想導入一個csv,我需要通過導軌或反正最快插入到數據庫中,所以我決定創建一個虛擬導軌應用程序來執行導入。以下是我在閱讀的博客中獲得的一些代碼。導入問題的產品
def upload
table = ImportTable.new :original_path => params[:upload][:csv].original_path
row_index = 0
FasterCSV.parse(params[:upload][:csv]) do |cells|
column_index = 0
cells.each do |cell|
table.import_cells.build :column_index => column_index, :row_index => row_index, :contents => cell
column_index += 1
end
row_index += 1
end
table.save
redirect_to import_table_path(table)
end
所有的工作都很好,但是csv的格式並沒有讓這個過程變得簡單。這是格式和我需要發生的事情。

對不起,如果它很難看,我做了我最好的格式。每行中的第一個元素是產品的名稱,所以我需要將其存儲在Product.name中,第二個元素是價格,以便在Product.price中使用。下一個就是我有問題
在循環 cells.each do |cell|
我需要檢查,看看我在該行的第三個元素,並做一些事情,第五元素,做另一件事
但我想細胞[2],得到了時髦的東西像這樣
Rails.logger.info "====3rd postion==========#{cell[3]}"
=> ====3rd postion===========79
