Django1.8 and Mongoengine NameError: name 'IntegerField' is not defined

Question

我在 Django 1.8 中使用 mongoengine，我的项目需要连接到 MongoDB 的一个实例，而另一个 sql.But 实例，我收到此错误-

命令提示符-

python manage.py runserver
Traceback (most recent call last):
  File "manage.py", line 11, in <module>
    execute_from_command_line(sys.argv)
  File "/var/www/html/admin_python/orahienv/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 338, in execute_from_command_line
    utility.execute()
  File "/var/www/html/admin_python/orahienv/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 312, in execute
    django.setup()
  File "/var/www/html/admin_python/orahienv/local/lib/python2.7/site-packages/django/__init__.py", line 18, in setup
    apps.populate(settings.INSTALLED_APPS)
  File "/var/www/html/admin_python/orahienv/local/lib/python2.7/site-packages/django/apps/registry.py", line 108, in populate
    app_config.import_models(all_models)
  File "/var/www/html/admin_python/orahienv/local/lib/python2.7/site-packages/django/apps/config.py", line 198, in import_models
    self.models_module = import_module(models_module_name)
  File "/usr/lib/python2.7/importlib/__init__.py", line 37, in import_module
    __import__(name)
  File "/var/www/html/admin_python/admin_app/models.py", line 212, in <module>
    class location(Document):
  File "/var/www/html/admin_python/admin_app/models.py", line 213, in location
    user_id = IntegerField(blank=True, null=True)
NameError: name 'IntegerField' is not defined

我的setting.py文件-

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'admin_db',
        'USER': 'root',
        'PASSWORD': 'root',
        'HOST': 'localhost',
    },

}

from mongoengine import connect
connect(
db='pom',
username='admin',
password='root',
host='mongodb://admin:root@localhost'
)

所以首先我决定完成与 mongodb 相关的所有工作，然后我将继续 sql.This 是 mongodb 数据库模型的代码
我的 model.py 文件 -

class location(Document):
        user_id = IntegerField(blank=True, null=True)
        name = CharField(max_length=100)
        loc_lon = FloatField(blank=True, null=True)
        timestamp = IntegerField(blank=True, null=True)
        activity = StringField()
        lot_lat = FloatField(blank=True, null=True)
        batter_status = StringField()
        address = StringField()
        date_created = DateTimeField(auto_now_add=True)

请问有人可以参考任何 MongoEngine 和 Django1.8 教程....

Answer 1

timestamp = IntField(blank=True, null=True)

但最好使用

timestamp = DateTimeField(blank=True, null=True) 

作为时间戳

Answer 2

IntergerField 无效，请改用 IntField。

user_id = IntField(blank=True, null=True)
