我正在编写一个脚本,将一些模型对象导入我的django应用程序使用的数据库中.在过去,我通过运行./manage.py shell然后解决了这个问题import myscript.我相信有更好的方法.我希望能够从我的HD上的任何地方调用脚本python scriptname.py,并且在该脚本的前几行中它将执行任何必要的导入/其他操作,以便它可以访问模型对象并且表现得好像它已经运行使用manage.py shell.

我需要添加到脚本中才能实现此目的？

编辑:

基于@Melug的回答,添加了动态设置的Python路径来解决问题中的"我的HD上的任何地方"部分:

import sys
sys.path.append('c:\\my_projec_src_folder')
from myproject import settings
from django.core.management import setup_environ
setup_environ(settings)

我正在使用此代码来填充我的数据库:

import os

    python_cat = add_cat('Python')

我正在尝试将项目从Django 1.6升级到1.7.到目前为止,我已经创建了一个具有所有相同安装的新virtualenv,并将Django版本升级到新版本.我需要从南升级,但有错误这样做,所以我想我最初只是尝试runserver,我得到以下错误:

当我今天想在服务器上部署django项目时,我一直坚持这个过程.当我python manage.py runserver在服务器上运行时,终端显示我:

我有一个项目,它不是一个django应用程序,而是一个芹菜应用程序.因此,我还没有创建一个wsgi.py或models.py或通过创建典型的文件django-admin时,一个项目或应用程序已启动.

我只想使用djcelery能够使用djcelery.schedules.DatabaseScheduler此处指定的类似方法创建周期性任务在运行时添加,修改,删除celery.schedules和此处如何动态添加/删除周期性任务到Celery(celerybeat)

这里给出的问题的解决方案(AppRegistryNotReady,使用uWSGI部署时的转换错误)要求我对vassal.ini文件进行更改.我的实现中没有vassal.ini文件.

我将简要介绍一下我的项目 -

  apps.py
  tasks.py
  celeryconfig.py
  runproj.py

• apps.py

    from celery import Celery
    os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'celeryconfig')
    myapp = Celery('myapp')

如何在解释器级别删除 Django 数据库中的一行。我正在对数据库进行故障排除，我希望能够定位 Django sqlite3 数据库中的特定行。

目前我可以在数据库中创建条目如下：

>> Item.objects.create(text='Item A')

我可以使用以下方法在数据库中查看：

>> for p in Item.objects.raw('SELECT * FROM appName_model'):
...    print(p.text)
...

我正确地获得了数据库内容（他们的文本字段）。

通过索引、text_field 或某些其他属性定位特定行时遇到问题。我直接在 Python 解释器上进行故障排除。
