django.core.exceptions.ImproperlyConfigured: Field name `tester_id` is not valid for model `WebCase`.

代码：

class WebCase(models.Model):
    id = models.AutoField(primary_key=True)
    casename = models.CharField("用例名称", max_length=200)
    caseresult = models.BooleanField("测试结果", default=False)
    casetester= models.ForeignKey(User, on_delete=models.CASCADE, verbose_name="测试负责人")
    module = models.ForeignKey(Module, on_delete=models.CASCADE, verbose_name="所属模块")
    update_time = models.DateTimeField("最近更改时间", auto_now=True)
    create_time = models.DateTimeField("创建时间", auto_now_add=True)

class WebCaseSerializer(serializers.ModelSerializer):

    module_id = serializers.IntegerField()
    tester_id= serializers.IntegerField()

    class Meta:
        model = WebCase
        fields = ('id', 'casename', 'caseresult', 'module_id', 'tester_id')

错误原因：

serializers.ModelSerializer中的字段与调用的model中的字段不一致，代码中已标注
更改后：

class WebCaseSerializer(serializers.ModelSerializer):

    module_id = serializers.IntegerField()
    casetester_id = serializers.IntegerField()

    class Meta:
        model = WebCase
        fields = ('id', 'casename', 'caseresult', 'module_id', 'casetester_id')
