Django 查询具有列表值的多个字段

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]。我想在上面的模型中查询 (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：我使用了author__email，这是一个嵌套查找 因为 author_list 包含 email_ids
