To answer your question directly - such scripts are run as <a href="https://docs.djangoproject.com/en/dev/howto/custom-management-commands/" rel="nofollow noreferrer">custom management commands</a>, but it would be simpler to use a pre-populated database like Northwind. See <a href="https://stackoverflow.com/questions/8552256/how-to-implement-northwind-in-django">this answer</a> on how how to implement it for django.

blocks|key|4213630|text|你可以使用django-whatever+(增强的django-any)+-它很容易创建虚拟数据。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|4213631|这是我的示例(+*app_name*/management/commands/dummyitems.py)：格式|4213632|class+Command(BaseCommand):

You can use <a href="https://github.com/coagulant/django-whatever" rel="nofollow">django-whatever</a> (enhanced django-any) - it easily creates dummy data.

Here is my sample (in *app_name*/management/commands/dummyitems.py):

<pre><code>class Command(BaseCommand):
 args = '[count]'

 def handle(self, count=20, *args, **options):

 try:
 i = int(count)
 except ValueError:
 print u'n is to be a number!'
 sys.exit(1)

 for _ in xrange(i):
 # you can pass params explicitly
 m = any_model(MY_MODEL_CLASS, image=None)
 m.save()
</code></pre>

And so if I need 100 dummy items I run:

<pre><code>$ python manage.py dummyitems 100
</code></pre>

blocks|key|4122532|text|首先安装这个包https://pypi.org/project/model-mommy/，然后在django+shell上运行这段代码。它会为项目中的所有模型生成假数据。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|4122533|from+django.apps+import+apps

First Install this package <a href="https://pypi.org/project/model-mommy/" rel="nofollow noreferrer">https://pypi.org/project/model-mommy/</a> and then
Run this code on django shell. It generates fake data for all of your models in project.
<pre><code>from django.apps import apps
from django.conf import settings
from model_mommy import mommy


for app in settings.INSTALLED_APPS:
 try:
 app_models = apps.get_app_config(app).get_models()
 except:
 continue
 for model in app_models:
 try:
 mommy.make(model, _quantity=100)
 except:
 print('error')
</code></pre>

To be able to see how my django application looks like, and performs with lots of data, i would like to programmatically generate data in the database. In the django documentation they propose either using fixtures oder SQL statements, but i would rather use a simple python loop to generate thousends of random entries by using the django model classes.

How can i execute such a script? I am using south for database migration, but even there such generation of data seems not to be supported.

为了能够看到我的django应用程序是什么样子，并在处理大量数据时执行，我希望以编程方式在数据库中生成数据。在django文档中，他们建议使用fixture或SQL语句，但我宁愿使用简单的python循环，通过使用django模型类来生成大量随机条目。如何执行这样的脚本？我正在使用south进行数据库迁移，但即使在那里...
