我有一段时间从我的POST阵列中抓取一个参数并将其插入MySQL数据库。该文件将提交给RAILS 3控制器,该控制器应该提取文件名并将其用作SQL语句中的值。这是我的控制者:
def upload
@item= Item.new(params[:qqfile])
Rails.logger.info("PARAMS: #{params.inspect}")
# if params array contains :qqfile
unless params[:qqfile].empty?
# model should:
# copy file to uploads directory
render_success
if @item.save
else
render :text => 'database did not save'
end
# redirect to render success action
else
render :text => '{success:false}'
end
end
日志显示查询正在运行但具有NULL值:

Completed 200 OK in 359ms (Views: 16.0ms | ActiveRecord: 0.0ms)
密钥在数组中。我很困惑为什么控制器没有将其值用于SQL查询中的值。
