Your migration looks generally correct, but there are a few things you might consider:

1. Default Value for null: The default value of None can be ambiguous because in Python, many types cannot be determined from just None. If you want to explicitly indicate that null is allowed, it's better to use models.TextField(null=True) instead.

2. Verbose Name: In Django, you typically only need to specify the verbose name if you're not using the default translation system, which is common these days. You could remove it entirely:

   field=models.CharField(max_length=10, null=True),

3. Consistent Field Definition: It would also make sense to have all fields defined consistently (e.g., whether they're required or optional). For example, blank=True could be added for any non-required string fields:

   field=models.CharField(max_length=10, blank=True, null=True),

Here's an optimized version based on these suggestions:

+            field=models.CharField(max_length=10, blank=True, null=True),
+        ),
+    ]

This version simplifies the model definition while maintaining clarity.

No issues found in your migration script. The structure is correct and follows best practices for altering fields in Django database migrations.

This code has some minor adjustments to improve clarity and functionality:

1. Null Check: The language field is now set to accept null=True, which allows for the possibility that it could be left empty.

    language = models.CharField(max_length=10, verbose_name="语言", default=None, null=True)

2. Default Value Removal: Removed the call to get_language in the default value of the language field since it no longer returns an object (it used to return either 'zh_CN' or 'en_US'). Instead, simply set it to None.

3. Minor Typographical Correction:

   • Changed verbose_name("是否显示知识来源") to verbose_name='是否显示知识来源'.

This should make the function more robust and handle edge cases like when the default option needs to be None.
