Question

我有这个型号：

class Comment(models.Model):
    comment_text = models.TextField("Comentário")
    user = models.ForeignKey(Profile)
    created = models.DateTimeField(auto_now_add=True, verbose_name="Criação")
    updated = models.DateTimeField(auto_now=True, verbose_name="Última modificação")
    confidential = models.BooleanField("Confidencial", default=False)

我有这个视图集（使用rest框架）：

    @detail_route(methods=['POST'], permission_classes= [IsOwnerOrReadOnly])
    def set_confidential(self, request, pk=None):
        comment = self.get_object()
        if(request.data.get("booleanField", None) != None):
            comment.confidential = request.data["booleanField"];
            comment.save()
            return Response({'from':'set_confidential','status':_("Confidential status changed")})
        else:
            return Response({"status":status.HTTP_400_BAD_REQUEST})

问题在于，当我通过＆＃34; False＆＃34;该视图的值是我的对象更新但字段＆＃34;机密＆＃34;仍然是真的（假设之前就是这样）。为什么会这样？

您应该保存comment对象。请注意，在布尔上下文中，任何非空字符串都被视为True：

comment.confidential = (request.data["booleanField"].lower() == 'true')
comment.save()

在django对象中保存方法不保存布尔模型字段，它传递给false
