models–serializers-permission-views-urls

1、创建models，
class TestSuit(BaseModel):

name = models.CharField('测试套件名称', max_length=200, help_text='测试套件名称')
task = models.ForeignKey(Task, verbose_name='测试任务', on_delete=models.PROTECT,
                             help_text='测试任务id', related_name='test_suits')

def __str__(self):
    return self.name

class Meta:
    db_table = 'tb_test_suit'
    verbose_name = '测试套件'
    verbose_name_plural = verbose_name
    constraints = [
        models.UniqueConstraint(fields=['name', 'task'],
                                name='unique_test_suit_name')
    ]

2、创建序列化，
class TestSuitSerializer(serializers.ModelSerializer):

class Meta:
    model = TestSuit
    exclude = ['u_time', 'is_delete']
    validators = [
        UniqueTogetherValidator(queryset=model.objects.all(),
                                fields=['name', 'task'])
    ]

3、创建权限
class TestSuitPermission(IsSuperUserOrReadOnly):

def has_create_permission(self, request, view, obj):
    """当前用户是否是当前项目的leader  创建测试套件的时候用的是task的id"""
    queryset = Task.objects.filter(pk=request.data.get('task'))
    return queryset and queryset.first().project.leader == request.user

def has_update_delete_permission(self, request, view, obj):
    """当前用户是否是当前项目的leader"""
    return obj.task.project.leader == request.user

3、创建views
class TestSuitViewSet(mixins.ListModelMixin,
mixins.CreateModelMixin,
GenericViewSet):
“”"
没有继承ModelViewSet，只是没有过度开发，只需要相应的查看list，和创建create接口
“”"
queryset = TestSuit.objects.all()
serializer_class = TestSuitSerializer
permission_classes = [IsAuthenticated, TestSuitPermission]
filterset_fields = (‘task’, )

4、写url
5、调试前端发现添加套件，但是任务没有套件，这是因为task里面没有嵌套testsuit,

在任务序列化，添加
test_suits = TestSuitSerializer(many=True, read_only=True)

把套件序列化放到任务序列化上面
