ORM'；比如'；django python中的查询

keywords=Donut使用

关键字\uuuu name\uuuu in=Donut

但是我需要得到结果

关键字\uuuu name\uuu in=Don

视图.py

items=ItemVariation.objects.filter(item__restaurant__id = i['restaurant']['id'],keyword__name__in=keyword,keyword__mood__moods=mood).select_related() 
# items=ItemVariation.objects.filter(item__restaurant__id = i['restaurant']['id'],keyword__name__contains=keyword,keyword__mood__moods=mood).select_related() # it is returning null
# items=ItemVariation.objects.filter(item__restaurant__id = i['restaurant']['id'],keyword__name__icontains=keyword,keyword__mood__moods=mood).select_related() 

class Keyword(models.Model):
    name=models.CharField(max_length=500,unique=True)
    image = models.ImageField(upload_to='keywords/', blank=True, null=True)
    mood=models.ManyToManyField(Mood,blank=True)
    def __str__(self):
        return str(self.name)

class ItemVariation(models.Model):
    restaurant=models.ForeignKey(Restaurant,on_delete=models.CASCADE)
    item=models.ForeignKey(Item,on_delete=models.CASCADE)
    price=models.IntegerField(blank=True,null=True,default=0)
    item_code=models.CharField(max_length=500)
    keyword= models.ManyToManyField(Keyword)
    image=models.ImageField(upload_to='dishes/', blank=True, null=True)

型号.py

items=ItemVariation.objects.filter(item__restaurant__id = i['restaurant']['id'],keyword__name__in=keyword,keyword__mood__moods=mood).select_related() 
# items=ItemVariation.objects.filter(item__restaurant__id = i['restaurant']['id'],keyword__name__contains=keyword,keyword__mood__moods=mood).select_related() # it is returning null
# items=ItemVariation.objects.filter(item__restaurant__id = i['restaurant']['id'],keyword__name__icontains=keyword,keyword__mood__moods=mood).select_related() 

class Keyword(models.Model):
    name=models.CharField(max_length=500,unique=True)
    image = models.ImageField(upload_to='keywords/', blank=True, null=True)
    mood=models.ManyToManyField(Mood,blank=True)
    def __str__(self):
        return str(self.name)

class ItemVariation(models.Model):
    restaurant=models.ForeignKey(Restaurant,on_delete=models.CASCADE)
    item=models.ForeignKey(Item,on_delete=models.CASCADE)
    price=models.IntegerField(blank=True,null=True,default=0)
    item_code=models.CharField(max_length=500)
    keyword= models.ManyToManyField(Keyword)
    image=models.ImageField(upload_to='dishes/', blank=True, null=True)

我有这个查询，我需要在=%keyword%中使用关键字名称

我正在使用PostgreSQL数据库 我为此传递的参数/？关键字=甜甜圈&情绪=约会

在

"items": [
            {
                "id": 7,
                "item": {
                    "name": "Donut",
                    "short_description": "Donuts"
                },
                "price": 0,
                "item_code": "test",
                "image": "/media/dishes/download_3_kcE78IS.jpeg",
                "restaurant": 1,
                "keyword": [
                    3
                ]
            }
        ],

使用icontains时的结果

“项目”：[]，

您正在寻找的项目（或

icontains

）

---

请分享（相关）模型。然后是

关键字\uuuu名称\uuuu icontains=keyword

。icontains不起作用，它返回的是空的，将示例数据和关键字值添加到您的问题中。但这里您可以查看

项目

是否有一家餐厅的

关键字名称

包含文本，并且对于该关键字，它包含一个特定的语气。@M4STER-“不工作”不是一个很好的描述。
