Question

我有以下Django模型

class Post(models.Model):
    author = models.ForeignKey(CustomUser,on_delete=models.CASCADE,)
    title = models.CharField(max_length=200,null=True)
    text = models.TextField()
    post_url = models.URLField(max_length = 200, blank = True)
    post_tier = models.ForeignKey(Tiers, on_delete=models.CASCADE, null= True)
    post_tier_value = models.IntegerField(default=0)
    slug = models.SlugField(unique=True, blank=True)

我有author_list = [author1@gmail.com, author2@gmail.com]和tier_value_list = [2000,3000]。我想在上述模型中查询(author = author1@gmail.com and post_tier_value <= 2000)或(author = author2@gmail.com and post_tier_value <= 3000)。

有人可以帮我查询一下吗？

Answer 1

使用 Q() 运算符

from django.db.models import Q

author_list = ['author1@gmail.com', 'author2@gmail.com']
tier_value_list = [2000, 3000]
query = Q()
for author, value in zip(author_list, tier_value_list):
    query = query | Q(author=author, post_tier_value__lte=value)

Post.objects.filter(query)

注意：：我使用的是 author__email ，它是自{{ 1}}包含email_ids

Django使用列表值查询多个字段
