我正在尝试安装MySQL_python适配器的1.2.2版本,使用使用该--no-site-packages选项创建的新virtualenv .PyPi中显示的当前版本是1.2.3.有没有办法安装旧版本？我发现一篇文章说这应该这样做:

pip install MySQL_python==1.2.2

但是,安装后,它仍会在站点包中显示MySQL_python-1.2.3-py2.6.egg-info.这是这个包特有的问题,还是我做错了什么？

对于OSX 10.6用户来说,这是一个备受争议的问题,但我找不到有效的解决方案.这是我的设置:

Python 2.6.1 64bit Django 1.2.1 MySQL 5.1.47 osx10.6 64bit

我用--no-site-packages创建了一个virtualenvwrapper,然后安装了Django.当我激活virtualenv并运行python manage.py syncdb时,我收到此错误:

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

尝试导入包含联系信息的CSV:

Name,Address,City,State,ZIP  
Jane Doe,123 Main St,Whereverville,CA,90210  
John Doe,555 Broadway Ave,New York,NY,10010 

运行此似乎不会向数据库添加任何文档:

$ mongoimport -d mydb -c things --type csv --file locations.csv --headerline

Trace说imported 1 objects,但启动Mongo shell并运行db.things.find()并不会显示任何新文档.

我错过了什么？

我的网站使用Django的用户身份验证用户模型和自定义UserProfile模型来存储一些额外的数据(生日等).有没有办法在Django管理员中创建一个视图,将来自User和UserProfile模型的字段编织在一起？

我怀疑这个代码片段甚至不是很接近,但它可能有助于说明我正在尝试做什么:

from django.contrib import admin
from django.contrib.auth.models import User
from userprofile.models import UserProfile


class UserProfileAdmin(admin.ModelAdmin):
    list_display = ('name', 'gender', 'User.email') #user.email creates the error - tried some variations here, but no luck.

admin.site.register(UserProfile, UserProfileAdmin)

错误信息:

NotperlyConfigured:UserProfileAdmin.list_display [2],'User.email'不是'UserProfileAdmin'的可调用或属性,或者在模型'UserProfile'中找到.

最终,我正在尝试创建一个管理视图,其中包含来自UserProfile的姓名和来自User的电子邮件.

这是这个问题的后续行动.如何在父级的内联中显示在子模型上定义的属性？为了说明,我有这个模型:

class UserProfile(models.Model):
    user = models.ForeignKey(User, unique=True, primary_key=True, related_name='profile')
    ...
    @property
    def age(self):
        if self.birthday is None:
            return None

        td = datetime.date.today() - self.birthday
        return td.days / 365

问题是:如何在用户的内联中显示"年龄"？这就是我所拥有的:

class UserProfileInline(admin.StackedInline):
    model = UserProfile
    fk_name = 'user'
    max_num = 1
    fieldsets = [
        ('Demographics', {'fields': ['birthday', 'age']}),
    ]

我尝试过这样的一些事情,包括'age()',为Inline定义'get_age'getter等等.它们导致了这个错误的某些版本:

ImproperlyConfigured: 'UserProfileInline.fieldsets[1][1]['fields']' refers to field 'age' that is missing from the form.

我无法使用我创建的任何超级用户登录Django admin.试图创建新的超级用户,更改密码等 - 没有任何这些进程的错误消息,但仍然无法登录.

我不确定它是否相关,但我也无法运行django-admin.py命令.这是我到目前为止所做的:

$ django-admin.py validate  
Error: Settings cannot be imported, because environment variable DJANGO_SETTINGS_MODULE is undefined.  
$ export DJANGO_SETTINGS_MODULE=mysite.settings  
$ django-admin.py validate  
Error: Could not import settings 'mysite.settings' (Is it on sys.path? Does it have syntax errors?): No module named mysite.settings

sys.path显示['/ Users/joerobinson/Sites/django/mysite'...(路径上的其他内容)]

注册mysite模块还需要做些什么吗？

python manage.py runserver工作正常.

结束语
关于登录django admin的问题,我没有在我的AUTHENTICATION_BACKENDS中包含django.contrib.auth.backends.ModelBackend - 添加这个允许我登录admin.

我还在研究django-admin.py配置问题(似乎没有关系),并将在一个单独的问题中重新打开它.

我正在通过Django教程并在运行初始python manage.py syncdb时收到以下错误:

Traceback (most recent call last):

我正在尝试使用MongoDB作为Celery的消息队列(在Django应用程序中).Celery(2.2.0rc2)的当前开发版本应该允许你这样做,但我似乎无法让任何工作人员去接受我正在创建的任务.

版本:芹菜v2.2.0rc3
mongodb 1.6.5
pymongo 1.9
django-celery 2.2.0rc2

在我的设置中,我有:

CELERY_RESULT_BACKEND = "mongodb"
CELERY_MONGODB_BACKEND_SETTINGS = {
    # Shouldn't need these - defaults are correct.
    "host": "localhost",
    "port": 27017,
    "database": "celery",
    "taskmeta_collection": "messages",
}

BROKER_BACKEND = 'mongodb'
BROKER_HOST = "localhost"
BROKER_PORT = 27017
BROKER_USER = ""
BROKER_PASSWORD = ""
BROKER_VHOST = ""

import djcelery
djcelery.setup_loader()

我已经创建了一个测试tasks.py文件,如下所示:

from celery.decorators import task

@task()
def add(x, y):
    return x + y

如果我在后台启动芹菜,它似乎正常启动.然后我打开一个python shell并运行以下命令:

>>> from myapp.tasks import add
>>> result = add.delay(5,5)
>>> result
<AsyncResult: …

我最近升级到python2.7并注意到tab键在shell中无法正常运行.相反,它似乎搜索基础目录(标准的unix行为).

如果我改回到python2.6,它会正常工作.有没有办法将此功能添加回2.7？

例如:

if foo :(
tab here)print'bar'#desired behavior is tab键在这里添加缩进

解决方案:
这是Mac OSX上python2.7的已知问题.我使用以下解决方法来纠正它:

$ cat > $HOME/.pystartup
import readline
if 'libedit' in readline.__doc__:
   readline.parse_and_bind("bind ^I ed-insert")
^D
$ export PYTHONSTARTUP=$HOME/.pystartup

我已经在我的Django项目中为Google OAuth2 实现了python-social-auth库，并能够成功使用它登录用户。该库将access_token收到的信息存储在Google OAuth2流的响应中。

我的问题是：使用google-api-python-client似乎依赖于创建和授权credentials对象，然后使用它来构建API，service如下所示：

...
# send user to Google consent URL, get auth_code in response

credentials = flow.step2_exchange(auth_code)
http_auth = credentials.authorize(httplib2.Http())

from apiclient.discovery import build
service = build('gmail', 'v1', http=http_auth)

# use service for API calls...

由于我是从access_tokenpython-social-auth提供的开始，因此如何service为未来的API调用创建和授权API客户端？

编辑：澄清一下，上面的代码来自Google提供的示例。
