Question

朋友们，我用form.py创建了一个表单，它运行得很顺利，但下次我在那个forms.py类中添加了两个新字段然后执行命令“python manage.py syncdb”它给出了我有以下错误：

Traceback (most recent call last):
  File "manage.py", line 11, in <module>

pysqlite2.dbapi2.OperationalError: unable to open database file

Answer 1

对表单进行更改不会影响数据库架构，更改表单后无需运行syncdb。您收到的错误源于其他地方。

Answer 2

似乎问题不在于您的forms.py，而在于您的sqlite数据库file.can您再次删除了sqlite数据库文件和syncdb


~$  rm default.db
~$ manage.py syncdb

在其中添加字段后，表单未运行
