是否可以使用正则表达式删除文本中的小词？例如,我有以下字符串(文本):

anytext = " in the echo chamber from Ontario duo "

我想删除3个字符或更少的所有单词.结果应该是:

"echo chamber from Ontario"

是否可以使用正则表达式或任何其他python函数？

谢谢.

我需要确定哪个文件是二进制文件,哪个文件是目录中的文本.

我试过使用mimetypes,但在我的情况下它不是一个好主意,因为它无法识别所有文件的mimes,我在这里有陌生人...我只需要知道,二进制或文本.简单吗？但我找不到解决方案......

谢谢

我最近在Django项目文档中创建了admin.py:

https://docs.djangoproject.com/en/dev/topics/auth/customizing/#django.contrib.auth.models.AbstractBaseUser

但我真的错过了允许管理员更改用户密码的功能.如何添加此功能？我只是复制并粘贴了上面链接中的代码.

from django import forms
from django.contrib import admin
from django.contrib.auth.models import Group
from django.contrib.auth.admin import UserAdmin
from django.contrib.auth.forms import ReadOnlyPasswordHashField

from customauth.models import MyUser


class UserCreationForm(forms.ModelForm):
    """A form for creating new users. Includes all the required
    fields, plus a repeated password."""
    password1 = forms.CharField(label='Password', widget=forms.PasswordInput)
    password2 = forms.CharField(label='Password confirmation', widget=forms.PasswordInput)

    class Meta:
        model = MyUser
        fields = ('email', 'date_of_birth')

    def clean_password2(self):
        # Check that the two password entries match
        password1 = self.cleaned_data.get("password1")
        password2 = self.cleaned_data.get("password2")
        if password1 …

我刚刚将我的django更新为1.4.但是当我尝试提交登录表单时出现以下错误:

禁止(403)CSRF验证失败.请求中止.失败原因:CSRF令牌丢失或不正确.

在我的settings.py(MIDDLEWARE_CLASSES)中,我不得不删除以下行,因为它现在已弃用:

'django.middleware.csrf.CsrfResponseMiddleware',

而且我开始得到这个错误.

一些必要的信息:Urls.py

url(r'^login/$', 'django.contrib.auth.views.login', {'template_name': 'registration/login.html'}, name='login')

是否可以使用Nginx和uWSGI在同一台服务器上运行多个Django站点？

我想有必要运行多个uWSGI实例(每个站点一个).我将/etc/init.d/uwsgi复制到uwsgi2并更改了端口号.但是,我收到以下错误:

# /etc/init.d/uwsgi2 start
Starting uwsgi: /usr/bin/uwsgi already running.

如何运行多个uWSGI实例？

谢谢

如何使用django_compressor将gziped文件发送到Amazon S3？

我尝试了几种方法,但它没有用.这是我上次的settings.py配置:

COMPRESS_ENABLED = True
COMPRESS_OFFLINE = True

COMPRESS_ROOT = STATIC_ROOT
COMPRESS_URL = "http://xxx.cloudfront.net/"
STATIC_URL = COMPRESS_URL
COMPRESS_OUTPUT_DIR = 'CACHE'

#COMPRESS_STORAGE = 'storages.backends.s3boto.S3BotoStorage'
COMPRESS_STORAGE = 'core.storage.CachedS3BotoStorage'

STATICFILES_STORAGE = 'compressor.storage.GzipCompressorFileStorage'
COMPRESS_YUI_BINARY = 'java -jar contrib/yuicompressor-2.4.7/build/yuicompressor-2.4.7.jar'
COMPRESS_YUI_JS_ARGUMENTS = ''
COMPRESS_CSS_FILTERS = ['compressor.filters.yui.YUICSSFilter']
COMPRESS_JS_FILTERS = ['compressor.filters.yui.YUIJSFilter']
COMPRESS_CSS_HASHING_METHOD = 'hash'

和我的storage.py

from storages.backends.s3boto import S3BotoStorage

class CachedS3BotoStorage(S3BotoStorage):
    """

我刚刚将我的django升级到了1.4.我在干草堆应用程序遇到麻烦.此外,我试图更新haystack到最后的稳定版本,但我仍然有问题.有没有人有这些错误？我该如何解决？

我收到以下错误.

当我访问任何页面时:

cannot import name MAX_SHOW_ALL_ALLOWED haystack\admin.py in <module>, line 2

和

# python manage.py rebuild_index
django.core.exceptions.ImproperlyConfigured: Error importing template source loader
django.template.loaders.app_directories.load_template_source:
    "'module' object has no attri bute 'load_template_source'"

我很怀疑...我创建了以下字典:

>>> alpha={'a': 10, 'b': 5, 'c': 11}

但是,当我想看到我得到的字典键和值时:

>>> alpha
{'a': 10, 'c': 11, 'b': 5}

看到"b"和"c"交换了他们的位置.如何使位置与创建字典时的位置相同？

我有一个中等流量的Django网站(每天大约4000/5000次访问).今天我在settings.py上配置了"LOGGING"选项,发送一个"Info"级别的电子邮件,只检查一切是否正常......

令我惊讶的是,我收到以下错误:[Django]警告(外部IP):禁止(CSRF cookie未设置.)

我刚刚将Django 1.4.2升级到1.5,我开始在django_compressor上出错.

You have offline compression enabled but key "eb225276268ea55d3b90c71df63109d9" is missing from offline manifest. You may need to run "python manage.py compress".

此外,我更新了django_compressor到最后一个版本(实际1.2),仍然得到相同的错误.

当我尝试python manage.py compress时,我注意到:

c:\python27\lib\site-packages\django\utils\hashcompat.py:9: DeprecationWarning: django.utils.hashcompat is deprecated; use hashlib instead DeprecationWarning)

此通知是否与脱机压缩错误有关？

[更新] 我发现另一个有趣的事情......

在我遇到问题的模板中,我删除了所有应该压缩的css:

 {% extends "base.html" %}
    {%  block head %}
        {% load compress %}
        {% compress css %}

        {% endcompress %}
    {% endblock %}
...

我运行python管理:

python manage.py compress 
python manage.py collectstatic   --noinput

没有错误.

但是......问题仍然存在.
