Model：

```

class TestCase(CoreModel):

name = models.CharField(max_length=50, verbose_name="测试用例名称", help_text="测试用例名称")

key = models.CharField(max_length=50, verbose_name="用例标识", help_text="用例标识")

status = models.BooleanField(default=True, verbose_name="状态", null=True, blank=True, help_text="状态")

project = models.ForeignKey(

to="project.Project",

verbose_name="所属模块",

on_delete=models.PROTECT,

db_constraint=False,

null=True,

blank=True,

help_text="关联模块",

)

```

序列化器：

```

class TestCaseSerializer(CustomModelSerializer):

"""

用例管理-序列化器

"""

project_name = serializers.CharField(source="project.name", read_only=True)

class Meta:

model = TestCase

fields = '__all__'

include = ["project_name"]

read_only_fields = ["id"]

def get_project_name(self, instance):

project_name_all = recursion(instance.project, "parent", "name")

project_name_all.reverse()

return "/".join(project_name_all)

```

前端列表字段这样用到：

```

column: {

minWidth: 200, //最小列宽

formatter({value, row, index}) {

return row.project_name

}

},```

我在新增数据的时候，报错提示：

```

django.core.exceptions.ImproperlyConfigured: Field name `project_name` is not valid for model `TestCase` in `apps.testcase.serializers.TestCaseCreateUpdateSerializer`.

```

用去年的版本没有问题，今年拉取更新版本后就出现这个问题了，是我配置问题还是需要修改哪里呢？
