django - Change value on POST before saving - 


@api_view(['get', 'post']) @csrf_exempt def index(request):     if   request.method == 'get':     queryset = test.objects.all()     return render(request, 'rest_framework/index.html', {'request':request, 'queryset':queryset})     elif request.method == 'post':     post_mutable = request.post.copy()         serializer = testserializer(data=request.data)     serializer.context = {'request': request}         if serializer.is_valid():             serializer.data['test'] = "testing"             serializer.save()             return response(serializer.data, status=status.http_201_created)         return response(serializer.errors, status=status.http_400_bad_request)

how can change data value before saving? change textfield "test".

you can override .save_object(obj) method on testserializer class. see docs.

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
