如何在Django（2.1）中添加自定义选择字段？

Question

这是模型类，用于存储有关应用程序的详细信息。在此模型中，可以添加自定义列表字段。即，用户应该能够定义一组选择，以后可以将其添加（作为标签）到应用程序的构建中。

class App(models.Model):
   bundle_number = models.CharField(max_length=255)
   hidden = models.BooleanField(default=False)

class Build(models.Model):
   app = models.ForeignKey(App, on_delete=models.CASCADE)
   number = models.CharField(max_length=255)
   uploaded_date = models.DateTimeField(auto_now_add=True)

Answer 1

# You can define a tuple in order to provide a list for your field

bundle_number_status = (
    (1, '1'),
    (2, '2'),
    (3, '3'),
)

# Now, Use bundle_number_status option in your field, for example you can use in bundle_number

class App(models.Model):
   bundle_number = models.CharField(max_length=255, choices=bundle_number_status)
   hidden = models.BooleanField(default=False)
