如何使用managed = False在Django测试期间创建表 [英] How to create table during Django tests with managed = False

问题描述

我有一个model = False的模型。

  class SampleModel（models.Model）：
 apple = models.CharField（max_length = 30）
 orange = models.CharField（max_length = 30）
 
 class Meta：
 managed = False 
  

我有一个单元测试创​​建一个SampleModel，但是当我运行测试我得到：

  DatabaseError：没有这样的表：SAMPLE_SAMPLE_MODEL 
  

django文档 - https://docs.djangoproject.com/en/dev/ref/models/options/#managed 记录以下内容：

对于涉及managed = False的模型的测试，由
确保正确的表创建作为测试设置的一部分。

如何在测试设置过程中实际创建表？或者，如何让我这样做，当我运行测试时，这个模型在测试期间有managed = True？

在实际的应用程序，该模型实际上由数据库中的视图支持。但是对于测试期间，我想把它当作表格，并且可以在其中插入测试数据。

I have a model with managed = False.

class SampleModel(models.Model):
    apple = models.CharField(max_length=30)
    orange = models.CharField(max_length=30)

    class Meta:
        managed = False

I have a unit test which creates a SampleModel, however when I run the test I get:

DatabaseError: no such table: SAMPLE_SAMPLE_MODEL

The django docs - https://docs.djangoproject.com/en/dev/ref/models/options/#managed documents the following:

For tests involving models with managed=False, it's up to you to ensure the correct tables are created as part of the test setup.

How can I actually "create" the tables during the test setup? Or alternatively, how can I make it so that when I am running tests, this model has "managed = True" for the duration of the test?

In the real application, this model is actually backed by a view in the database. However for the during of the test, I would like to treat this as a table and be able to insert test data in there.
