Django休息框架，序列化程序 - 用POST方法提交后不会返回主页
我是这里的django新手。我很困惑，为什么在我提交了一个POST请求之后，django rest框架会引导我到这里这个页面
而不是让我回到我的主页
这是我的 views.py：class TableData(APIView):
def post(self,request,*args,**kwargs):
startRange = request.POST.get('mcap')
endRange = int(startRange) + 29868
sector = request.POST['cat']
print(str(sector))
stocks = StockInfo.objects.filter(Q(company__company_categories__contains=sector),Q(companymcap__range=(startRange,endRange)),Q(datetimecollect__contains=datetime.date(2018,3,13)))
serializer = TableSerializer(stocks,many=True)
return Response(serializer.data)
我的serializers.py：
class TableSerializer(serializers.ModelSerializer):
#stocks = serializers.StringRelatedField(many=True)
company_name = serializers.CharField(source='company.company_name')
company_id = serializers.IntegerField(source='company.company_id')
company_categories = serializers.CharField(source='company.company_categories')
class Meta:
model = StockInfo
fields = ('company_name', 'company_id', 'company_categories','companyprice', 'companyvolume', 'companyeps', 'companydps', 'companynta', 'companype', 'companydy', 'companyroe', 'companyptbv', 'companymcap')
我最初的想法是，一个人从我的html表单中选择了一些标准，然后当他们提交表单时，我将根据他们的标准查询数据库并将其加载到序列化程序中。然后使用序列化程序在我的html页面中填充我的ajax数据表。
我尽我所能，但我仍然不知道出了什么问题......
EDITED
让我说如果我和ajax datatable一起使用...我是否仍然像我重定向我的页面一样这样做？ 在我的mypage.html
中的ajax数据表的片段中$(document).ready(function() {
var table = $('#datatable').dataTable( {
"processing": true,
"searching": false,
"ajax": {
"processing": true,
"url": "{% url 'tableData' %}",
"dataSrc": ""
},
"columns": [
{ "data": "company_name" },
{ "data": "company_id" },
{ "data": "companyprice" },
{ "data": "companyvolume" },
{ "data": "companyeps" },
{ "data": "companydps" },
{ "data": "companynta" },
{ "data": "companype" },
{ "data": "companydy" },
{ "data": "companyroe" },
{ "data": "companyptbv" },
{ "data": "companymcap" }
]
} );
} );
网址：{％url'tableData'％}将指向url / api / table / data。
再次编辑
这是我的html模板

UPDATE：解决
在我的html中的数据表中我做了这个
$(document).ready(function() {
var json = JSON.stringify({{data | safe}});
$('#datatable').DataTable({
"data": JSON.parse(json),
"columns": [
{ "data": "company_name" },
{ "data": "company_id" },
{"data": "company_categories"},
{ "data": "companyprice" },
{ "data": "companyvolume" },
{ "data": "companyeps" },
{ "data": "companydps" },
{ "data": "companynta" },
{ "data": "companype" },
{ "data": "companydy" },
{ "data": "companyroe" },
{ "data": "companyptbv" },
{ "data": "companymcap" }
]
});;
} );
在我的views.py中我做了这个
views.py
stocks = StockInfo.objects.filter(Q(company__company_categories__contains=sector),Q(companyprice__range=(startPriceRange,endPriceRange)),Q(companymcap__range=(startRange,endRange)),Q(datetimecollect__contains=datetime.date(2018,3,13)))
serializer = TableSerializer(stocks,many=True)
#qs = serializers.serialize('json',stocks)
testing = json.dumps(list(serializer.data))
context = {'data':testing,}
return render(request,'mypage.html',context)

答案 0 :(得分：0)
您未在视图中指定任何template_name，并且您将APIView作为子类，因此将您带到该页面（图片）是正常的。
在主页模板或drf render中使用django HTMLRenderer功能：
from rest_framework.renderers import TemplateHTMLRenderer
class TableData(APIView):
def post(self,request,*args,**kwargs):
startRange = request.POST.get('mcap')
endRange = int(startRange) + 29868
sector = request.POST['cat']
print(str(sector))
...
serializer = TableSerializer(stocks,many=True)
renderer_classes = [TemplateHTMLRenderer]
template_name = 'homepage.html'
return Response({'data': serializer.data})
data是您在首页模板中使用的变量，可以使用serializer.data。
