sqlalchemy.exc.ProgrammingError: (_mysql_exceptions.ProgrammingError) (1146, "Table 'xxx.authority' doesn't exist")

• 操作

  • 我是在写项目中把全部的表都删了, 然后进行新建

  if __name__ == '__main__':
      db.create_all()
  
  

• 报错内容

  The above exception was the direct cause of the following exception:
  
  Traceback (most recent call last):
       省略...............
  File "XXXappadminforms.py", line 10, in <module>
      authority_list = [(v.id, v.name) for v in Authority.query.all()]
       省略...............
  sqlalchemy.exc.ProgrammingError: (_mysql_exceptions.ProgrammingError) (1146, "Table 'xxx.authority' doesn't exist") [SQL: 'SELECT authority.id AS authority_id, authority.name AS authority_name, authority.url AS authority_url, authority.add_time AS authority_add_time 
  FROM authority'] (Background on this error at: http://sqlalche.me/e/f405)
  
  Process finished with exit code 1
  

• 分析

  • 我们可以从上述内容中知道他是,表不存在,然而他却在forms.py先进行查询, emmmmmmm

• 解决方法

  • 在forms.py中先将查询部分注释, 执行完db.creat_all()后,再去掉注释

  authority_list = []
  #authority_list = [(v.id, v.name) for v in Authority.query.all()]
