Multiple Formsets on Same Page Submission through Ajax
So I have two formsets being rendered on the same page, which I intend to submit through AJAX. The problem is whenever I try to submit the forms, I get the error: code='missing_management_form', django.core.exceptions.ValidationError: ['ManagementForm data is missing or has been tampered with'] I've tried changing the prefixes and adding the management form tags in the template but still doesn't change. Here's my forms.py; from .models import Declaration, Spouse, Child from django import forms from django.forms import inlineformset_factory from django.contrib.auth import get_user_model User = get_user_model() class ChildrenForm(forms.ModelForm): class Meta: model = Child fields = ['declarant','surname', 'first_name', 'other_names'] class SpousesForm(forms.ModelForm): class Meta: model = Spouse fields = ['declarant','surname', 'first_name', 'other_names'] SpousesFormSet = inlineformset_factory(User, Spouse, form=SpousesForm, extra=1) ChildrenFormSet = inlineformset_factory(User, Child, form=ChildrenForm, extra=1) And the view: def add_newly_recruited_officers_step_2(request): if request.POST: if request.is_ajax: spousesformset = SpousesFormSet(request.POST, instance=request.user) childrenformset = ChildrenFormSet(request.POST, instance=request.user) if spousesformset.is_valid() and childrenformset.is_valid(): return JsonResponse({'success': "Data Saved Successfully"}) else: return JsonResponse({'error': {'spousesformset': spousesformset.errors, 'childrenformset': childrenformset.errors}}) else: spousesformset = SpousesFormSet(instance=request.user) childrenformset = ChildrenFormSet(instance=request.user) context = { 'spousesformset': spousesformset, 'childrenformset': childrenformset, } return render(request, 'declarations/newly_recruited/form_step_2.html', context) The URL path is: path('add-newly-recruited/step2/', add_newly_recruited_officers_step_2, name='add-newly-recruited-officers-step-2'), And the template: <!-- Form 1--> <form action="{% url 'add-newly-recruited-officers-step-2' %}" method="POST" id="form1"> {% csrf_token %} {{ spousesformset.management_form }} <table … -
Django grouped annotation percentage with a single query
What I'm trying to do is work out the percentage of amount for each weekday, I know how to do it in two queries, but I'm wondering if there is a way to do it in one? For example, if I have the model: class DailyAmount(models.Model): date = models.DateField() amount = models.DecimalField() I can get the percentage amounts for each weekday in two queries like so: total_amount = models.DailyAmount.objects.all().aggregate(total=Sum("amount"))["amount"] result = models.DailyAmount.objects.all().annotate( weekday=ExtractWeekDay("date") ).values("weekday").annotate( percentage=ExpressionWrapper( Sum("amount") * 100.0 / total_amount, output_field=DecimalField() ) ) Is there a way to combine them? I've looked into both Subquery and Window, but I can't get either to quite work and I'm sure I'm missing something. -
Django, how to use filter to check if string field is a substring of a parameter?
I have a model in Django like this - class City: name = models.CharField(max_length=255) Now the below query can filter if the parameter string is a substring of the name field in the City model -- results = City.objects.filter(name_icontains=<some_string>).all() So suppose one of the rows in the database for city table has name = "new york city", so if the give the querystring as "new york", the above filter query will match with it since "new york" is contained in the "new york city". Now after reading the answer to this question -- Django, how to use filter to check if string field is contained in parameter I could solve this by breaking the querystring into words and then applying filter query for each of them. However, how to solve this if my querystring is not two separate words but a long word. Here is an example - Suppose one row for city table contains name as "newyork" and my query string is "newyorkcity", now I can not break the "newyorkcity" querystring into separate words and apply separate filtering. So how can I solve this problem so that when I search for rows matching name as "newyorkcity", it should return … -
Django ORM : model with a list of items from another model
In my Django models, I have two models : one called Site and the other SiteFeature. Object-wise, it is very clear how this should work : every instance of the Site class should have as property a list containing instances of the SiteFeature class, simply because the SiteFeature objects should only exist in relation to a Site object. Database-wise, it is also very clear how it should work : the SiteFeature table should contain a not-nullable column referencing the primary key id column of the Site table, with a foreign key. But in terms of Django ORM, I don't know how to code this. Based on this question, and this other example, it seems the classical way to proceed works the other way round : The Site model class contains no ORM model field referencing the SiteFeature list. Instead, the SiteFeature ORM model class has a ForeignKey field referencing the Site class. I see there is a way to code this out : by adding a function to the Site model class that searches all the related SiteFeature, and make this function a property (decorator @property): @property def site_features(self): return SiteFeature.objects.filter(site_id=site_id) But that leaves me doubts : The proper logic … -

This custom method need to remain in the ShowcaseViewSet to maintain a correct rest url. What can I do here to solve my problem ? -

Django ordering search results from get_queryset(self)
I am using django 2.2.10. I have a searchbar which returns search results to the showpage, using get_queryset(self) in searchresultsview(listview) class. I have set paginate_by=10. In the front-end I made links to order the table: ` <th>Title original <a href="?order_by=title_original&direction=asc" class="arrow up"></a> <a href="?order_by=title_original&direction=desc" class="arrow down"></a></th> At the start of the get_queryset(self) function I have the following code: order_by = self.request.GET.get('order_by') direction = self.request.GET.get('direction') if order_by is not None and order_by != "" and direction is not None and direction != "": ordering = Lower(order_by) if direction == 'desc': ordering = '-{}'.format(ordering) publications = Publication.objects.filter(is_deleted=False).order_by(ordering) ''' paginator = Paginator(publications, 10) page = self.request.GET.get('page') try: all_publications = paginator.page(page) except PageNotAnInteger: all_publications = paginator.page(1) except EmptyPage: all_publications = paginator.page(paginator.num_pages) ''' return publications The main problem is that the publications variable contain all publications, I want to restrict it to the publications from the previous get_queryset(self) call. Also the showpage is paginated (paginate_by = 10 in template).The ordering for descending does not work I get: invalid order_by arguments: ['-Lower(F(title_original))'] . If I order ascending it logically does not keep my search results. I tried finding a stackoverflow solution but the explanation is minimal. Any help would be appreciated. -

So I am trying to implement file upload to my website. It is something I have done before but right now in my views the form does not pass the if request.method=="POST" line. Here is my code: settings.py: ... MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, 'media/') urls.py: urlpatterns=[ ... path('filepost/', views.filepost, name='filepost') ]+ static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) models.py ... class File(models.Model): user=models.ForeignKey(get_user_model(), on_delete=models.CASCADE, related_name='files', null=True) file=models.FileField(upload_to='files/') forms.py ... class FileForm(forms.Form): file=forms.FileField(label='') home.html: ... <form action="{%url 'filepost'%}" method="post" enctype="multipart/form-data"> {%csrf_token%} {{fileForm}} <button type="button">Post File</button> </form> views.py: ... def filepost(request): form=FileForm() if request.method=='POST': print(1) form=FileForm(request.POST, request.FILES) if form.is_valid(): file=request.FILES['file'] newupload=File(user=request.user, file=file) newupload.save() return redirect('../') I have the print(1) in the views to check if it gets past the if request.method=="POST" line but it doesn't print 1 so I am guessing that this line is the problem. Any ideas? Thanks!
