无法创建测试数据库django

Question

我正在尝试测试 Django 应用程序，但是当我运行 python manager.py 测试时我遇到了这个错误

django.db.utils.ProgrammingError: column deals_dealproposal.billing_branch_launcher_id does not exist

它发生在

 File "/migrations/0008_dynamicpackingtype.py", line 18, in run
for proposal in bulk_proposals:

在这一点上，billing_branch_launcher 并不真正存在，它是在迁移 27

中创建的

migrations.AddField(
        model_name='dealproposal',
        name='billing_branch_launcher',
        field=models.ForeignKey(null=True, on_delete=django.db.models.deletion.PROTECT, related_name='billing_branch_launcher', to='clients.CoffeeCompany'),
    ),

迁移 8 看起来像这样

class Migration(migrations.Migration):

dependencies = [
    ('coffeedeals', '0007_auto_20190315_1642'),
    ('schemas', '0003_dynamicpackingtype')
]

def run(app, schema_editor):
    bulk_proposals = md.DealProposal.active.filter(
        data__negotiation__packing='bulk',
        data__negotiation__packing_type__isnull=False)

    for proposal in bulk_proposals:
        del proposal.data['negotiation']['packing_type']
        proposal.save()

operations = [migrations.RunPython(run, atomic=True)]

我该如何解决？

Answer 1

我建议安装 python 库

django-test-without-migrations

那么迁移文件错误不会影响测试。

pip install django-test-without-migrations

添加到INSTALLED_APPS (settings.py)

Then run :

python manage.py test --nomigrations

参考：https://pypi.org/project/django-test-without-migrations/
