我想在pyCharm中运行我的第一个Django cassandra代码。
我的代码在Django控制台中运行平稳,但不能在.py文件中运行。这些都是错误的:我的第一个Django cassandra代码中的一些错误
C:\Python27\python.exe "D:/Developer Center/PyCharm/DJangoCassandra/MyApp/testFile.py"

这是我的.py文件:
__author__ = 'ehsan'
from cqlengine import connection
from MyApp.models import Person
from cqlengine.management import sync_table,drop_table
def main():
connection.setup(['127.0.0.1:9160'])
sync_table(Person)
Person.create(id='2',name='Ali',family='Rezayee')
p = Person.objects.all()
for item in p:
print item.id
Person.filter(id='1')
这是我的模型:
from django.db import models
from cqlengine import Model, columns
# Create your models here.
class Person(Model):
id = columns.Text(primary_key=True)
name = columns.Text()
family = columns.Text()
你是什么意思“不在.py文件中工作”?你如何试图运行你的代码?你得到的错误是由于它无法找到你的项目的settings.py文件。它在Django控制台中工作的原因是因为当你运行'manage.py shell'时,它默认知道在哪里查找'settings.py' – ptr
