【问题描述】：

在我的项目中，如何获取所有 post_status 的帖子，例如发布、待处理、草稿、垃圾邮件。我想用 post_status 查询。

后模型

 ` 

class Post(models.Model):

    title = models.CharField(max_length=255)
    slug = models.CharField(max_length=255, unique= True,  editable=False)
    author = models.ForeignKey(User, on_delete=models.CASCADE)
    subtitle = models.CharField(max_length=255, null=True, blank=True)
    description = models.TextField(max_length=5555, null=True, blank=True)
    image = models.ImageField(blank=True, upload_to=post_image_path)
    image_caption = models.CharField(max_length=255, blank=True)
    post_status = models.CharField(max_length=255)
    comment_status = models.CharField(max_length=255)
    post_type = models.CharField(max_length=50)
    comment_count = models.IntegerField(null=True, blank=True)
    categories = models.ManyToManyField(Category,  blank=True)
    tags = models.ManyToManyField(Tag, blank=True)
    createdAt = models.DateTimeField(auto_now_add=True)
    updatedAt = models.DateTimeField(auto_now=True)


    def save(self, *args, **kwargs):
        self.slug = slugify(self.title)
        super(Post, self).save(*args, **kwargs)

    def __str__(self):
        return self.title

`

序列化器.py

from .models import Post

class PostSerializer(serializers.ModelSerializer):

    class Meta:
        model = Post
        fields = '__all__'
        read_only_fields = ['author']

视图中如何实现？

【解决方案1】：

下面的 sn-p 应该适用于您的查询。

class PostListView(generics.ListAPIView):
    serializer_class = PostSerializer

    def get_queryset(self):
        queryset = Post.objects.all()
        post_status = self.request.query_params.get('post_status')
        if username is not None:
            queryset = queryset.filter(post_status=post_status)
        return queryset

截图改编自Django Rest Framework - Filtering

【解决方案2】：

views.py

from django.db.models import Q
from .serializers import PostSerializer
from rest_framework.generics import ListAPIView
from .models import Post

class PostListAPIView(ListAPIView):
    serializer_class = PostSerializer

    def get_queryset(self):
        queryset = Post.objects.filter(Q(post_status__contains='publish') | Q(post_status__contains='pending') | Q(post_status__contains='draft') | Q(post_status__contains='spam'))
        return queryset
