我读了django-rest-framework nested-relationships :
您可以在tracks
中看到AlbumSerializer
:
class TrackSerializer(serializers.ModelSerializer):
class Meta:
model = Track
fields = ('order', 'title', 'duration')
class AlbumSerializer(serializers.ModelSerializer):
tracks = TrackSerializer(many=True, read_only=True)
class Meta:
model = Album
fields = ('album_name', 'artist', 'tracks')
官方网站没有提供一种方法来分隔tracks
AlbumSerializer
,如果曲目数量过大,如何实现曲目的分页?
修改
我想通过将页码传递给API来对其进行分页。
答案 0 :(得分:-1)
Django have some paginator classes that can help you build it on your own.
如果你想建立一个分页,你可以这样做:
from django.core.paginator import Paginator
def viewPage(request, page):
paginator = Paginator(data, 10) # 10 being how many objects per page you want, data being an array of tracks
try:
tracks = paginator.page(page)
except PageNotAnInteger:
# If page is not an integer, deliver first page.
tracks = paginator.page(1)
except EmptyPage:
# If page is out of range (e.g. 9999), deliver last page of results.
tracks = paginator.page(paginator.num_pages)
return render(request, 'view_page.html', {
'tracks': tracks,
})
您需要为Paginator()提供的数据是整个轨道集合作为可迭代的。
