# File 1
me = MongoEngine(app) # I want to use my instance of MongoEngine to define new classes like the example in File 2
# File 2
class Book(me.Document):
title = StringField(null=False, unique=True)
year_published = IntField(null=True)
在新文件中创建新类时,如何将实例 me.Document
作为对象定义传递。如果我将它们放在同一个文件中,它会起作用吗?
最佳答案
我认为选择为答案的答案并不完全正确。
File1.py
似乎是您执行的主要脚本,
File2.py
是一个模块,其中包含您希望在 File1.py
class
同样基于 previous question of the OP我想建议以下结构:
File1.py 和 File2.py 位于同一个目录
File1.py
import MongoEngine
from File2 import Book
me = MongoEngine(app)
# according to the documentation
# you do need to pass args/values in the following line
my_book = Book(me.Document(*args, **values))
# then do something with my_book
# which is now an instance of the File2.py class Book
File2.py
import MongoEngine
class Book(MongoEngine.Document):
def __init__(self, *args, **kwargs):
super(Book, self).__init__(*args, **kwargs)
# you can add additional code here if needed
def my_additional_function(self):
#do something
return True
