迁移Django 1.11

Question

为什么当我尝试为我添加的每个模型迁移模型时，尽管有些错误，例如：

我不想删除并创建另一个数据库。我只想改变现有的数据库，如果我的数据库中有一些数据？在

(1054, "Unknown column 'vacina_agentmodel.phone' in 'field list'")
(1054, "Unknown column 'created' in 'vacina_vaccinemodel'")

初始迁移

嘿，在你的应用程序文件夹里会有一个名为migrations的文件夹试着删除格式为001的所有文件_初始.py然后在命令提示符下运行makemigrations命令，这允许您在不删除整个数据库的情况下编辑模型。在
