How to iterate formsets with inline structure
I face up with the problem of inability to iterate through my formsets. I have already create an inline structure between Client model(form) and Phone model(formset). My aim is to be able to store more than one phone for each client. The issue is that despite the fact that I can create more than one inlines, when it comes the phase of storing, my code only stores the last phone and not each phone as expected. models.py class Client(models.Model): name = models.CharField(max_length=50, verbose_name="Όνομα") surname = models.CharField(max_length=50, verbose_name="Επίθετο") amka_amesa = models.BigIntegerField( validators=[MaxValueValidator(99999999999)],null=True,blank=True, verbose_name="AΜΚΑ Άμεσα Ασφαλισμένου") amka_emesa = models.BigIntegerField( validators=[MaxValueValidator(99999999999)], unique=True, null=True, blank=True, verbose_name="ΑΜΚΑ Έμεσα Ασφαλισμένου") am_asfa = models.CharField( max_length=11, validators=[RegexValidator(r'^\d+$')], null=True, blank=True, verbose_name="Α.Μητρώου Ασφαλισμένου") address = models.CharField(max_length=100, null=True, blank=True, verbose_name="Διεύθυνση") ika_branch = models.ForeignKey(Client_IKA_Branch, null=True, blank=True, verbose_name=u'Υποκατάστημα Ασφαλισμένου') notes = models.CharField(max_length=100, null=True, blank=True, verbose_name="Σημειώσεις") #active field=1 #inactive field=0 INACTIVE, ACTIVE = range(0, 2) ACTIVITY_OPTIONS = ( (INACTIVE, 'Ανενεργός'), (ACTIVE, 'Ενεργός'), ) activity = models.IntegerField(choices=ACTIVITY_OPTIONS, null=True,default=ACTIVE) class Phone(models.Model): MOBILE, WORK, HOME = range(0, 3) CATEGORIES = ( (MOBILE, 'Κινητό'), (WORK, 'Δουλειά'), (HOME, 'Σπίτι'), ) number = models.CharField(max_length=14, null=True) category = models.IntegerField(choices=CATEGORIES, null=True,default=MOBILE) client = models.ForeignKey(Client, null=True) def __unicode__(self): return self.number def get_absolute_url(self): return reverse('client_list') forms.py class ClientForm(ModelForm): class Meta: model = Client exclude=('activity',) … -
How to send dict of dict from Django to javascript
I want to send data from Django to JavaScript so I can write all logic in JS + Vue and keep html clean. In Django I have context={'names':{'fn':'john','ln':'cena'}} return render(request,'app/page1.html',context) in page1.html template I have <script type="text/javascript"> var names="{{names}}"; </script> In javascript how can I access names.fn & names.ln ? I have two more related questions: Is this a preferred Django way to send data directly from Django to JS when template is rendered. (The only other method I know is through Ajax call. Here I dont want to do additional Ajax call after the page is rendered) From security stand point, is it better to keep Django data related logic {% if x > y %} inside templates or is it ok to move the logic part to JS + Vue and just keep data structure in the template. I ask this because when i check page source in a browser window, I can see entire JS code but I cannot see anything that's inside a Django condition statement in html : {% if x>y %} ----THIS IS INVISIBLE IN A BROWSER---- {% endif %} Thanks -

How to store data in database from views.py Django?
This is my models: class ledger1(models.Model): name = models.CharField(max_length=32) Closing_balance = models.DecimalField(max_digits=10,decimal_places=2,blank=True,null=True) class journal(models.Model): Date = models.DateField(default=datetime.date.today) By = models.ForeignKey(ledger1,on_delete=models.CASCADE,related_name='Debitledgers') To = models.ForeignKey(ledger1,on_delete=models.CASCADE,related_name='Creditledgers') Debit = models.DecimalField(max_digits=10,decimal_places=2,null=True) Credit = models.DecimalField(max_digits=10,decimal_places=2,null=True) And in my views I have done this: qscb = journal.objects.filter(User=request.user, Company=company_details.pk, By=ledger1_details.pk, Date__gte=selectdatefield_details.Start_Date, Date__lte=selectdatefield_details.End_Date) qscb2 = journal.objects.filter(User=request.user, Company=company_details.pk, To=ledger1_details.pk, Date__gte=selectdatefield_details.Start_Date, Date__lte=selectdatefield_details.End_Date) total_debitcb = qscb.aggregate(the_sum=Coalesce(Sum('Debit'), Value(0)))['the_sum'] total_creditcb = qscb2.aggregate(the_sum=Coalesce(Sum('Credit'), Value(0)))['the_sum'] if(ledger1_details.group1_Name.balance_nature == 'Debit'): closing_balance = opening_balance + total_debitcb - total_creditcb else: closing_balance = opening_balance + total_creditcb - total_debitcb I want to store the value of 'closing_balance' into my model field named 'Closing_Balance'....And automatically update it when any changes are made... Any idea anyone how it is possible in django? Thank you -
Download Static Files by name Django
I am new to Django and am creating a site where user uploads a file (test.png etc). The file is then processed and a new file (test.csv) is created in the local directory. ../django/myproject/mysite/csv/test.csv Users can keep uploading files and more .csv files are created. A result page will show the .csv files and the user can download those files. However, I'm confused as I can't download them. views.py def make_csv(request): ... csv_filename = str(in_csv_file) #send to result page return render(request,'thesite/results.html', {"csv_filename": csv_filename}) views.py (same as above file) def download_csv(request, csvfile): path = os.path.join(SETTING_DIR) filename = path + csvfile + ".csv" filewrapper = FileWrapper(open(filename, 'rb')) response = HttpResponse(filewrapper, content_type='text/csv') response['Content-Length'] = os.path.getsize(filename) response['Content-Disposition'] = 'attachment; filename="{}"'.format(csvfile +".csv") return response results.html <tbody> <tr> <td></td> <td>{{csv_filename}}</td> <td><a href='/thesite/download_csv/{{csv_filename}}' do i add something here? >Download</a></td> </tr></tbody> urls.py urlpatterns = [ ... path('results/', views.results, name='results'), path('download_csv/(?P<csvfile>.+)$/', views.download_csv, name='download_csv'), or do I add smt here??] I'm sorry if my question is unclear. Thank you for your help. -

django rest framework - POST request causes 400 status code
I am trying to perform a POST request to create an article and I am getting this error Request failed with status code 400. An article needs 3 attributes to be created: (1) title (2) body (3) author (the current user) The router works fine since the POST request goes into the post method of the ArticleCreateView class. But the serializer = ArticleSerializer(data=request.data) doesn't invoke the create method of the ArticleSerializer class for some reason. I can see the output of print('inside the post method') in the Terminal. But I cannot see the output of print('inside the create method'). Another mystery about Django is, how does the serializer know if I want to get, create or update something? In all the examples I've seen, the serializer magically seems to know this. class ArticleCreateView(CreateAPIView): permission_classes = [IsAuthenticated] def post(self, request): print('inside the post method') serializer = ArticleSerializer(data=request.data) if serializer.is_valid(): serializer.save() return Response(serializer.data) return Response(serializer.errors) class ArticleSerializer(serializers.ModelSerializer): class Meta: model = Article fields = '__all__' def create(self, validated_data): print('inside the create method') author = self.context['request'].user title = validated_data.get('title') body = validated_data.get('body') return Article.objects.create(author=author, title=title, body=body) -
Creating plain API which accepts files
I am building an API which accepts file and validates it, sends json response (not storing the file in db, so no need of model). I have created a class based view, in post function, request.FILES or request.POST doesn’t contain the file… If I make a form class, it will work. But, I don’t want any UI, it should be a simple API. Anyone knows how to do it? class ValidateView(View): def get(self, request, *args, **kwargs): pass def post(self, request, *args, **kwargs): file = request.FILES if not file: return JsonResponse({"status_code": "400", "message": "a file is required", "status_response": "Bad Request"}) return JsonResponse({"status_code": "200", "message": "data validated", "status_response": "Success"}) @csrf_exempt def dispatch(self, request, *args, **kwargs): return super(ValidateView, self).dispatch(request, *args, **kwargs) I used djangorestframework and come up with this class ValidateView(views.APIView): parser_classes = (FileUploadParser,) def post(self, request, filename, format=None): file_obj = request.data['file'] if is_csv_valid(file_obj): return Response(status=200, data={"message": "valid file"}) else: return Response(status=400, data={"message": "not valid"}) But, here the problem is I must build a url like this re_path("validate/(?P<filename>[^/]+)$", ValidateView.as_view(), name="api-validate") If I exclude filename in url, it throws an error. Also, file_obj contains some extra lines (Content-Type) along with original data. Someone help!!! -
Can't runserver on Django
I just started playing with Django, and I encountered a problem. Here's what it said when I tried to runserver. ImproperlyConfigured: The included URLconf '' does not appear to have any patterns in it. If you see valid patterns in the file then the issue is probably caused by a circular import. Here's what I did. On setting.py: INSTALLED_APPS = [ 'Siblog.apps.SiblogConfig', 'django.contrib.admin', 'django.contrib.auth',**strong text** 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', ] Project urls.py: from django.contrib import admin from django.urls import path, include urlpatterns = [ path('admin/', admin.site.urls), path('', include('Siblog.urls')), ] Siblog urls.py: from django.urls import path from . import views urlpatterns = [ path('', views.home, name='Siblog-home'), ] Siblog views.py: from django.shortcuts import render def home(request): return render(request, 'Siblog/home.html') Also the template I've created inside of the Siblog file: <!DOCTYPE html> <html> <head> <title></title> </head> <body> <h1>Siblog Home!</h1>> </body> </html> -
Searching Across Django Models against Search Form Query
I've been reading up on Django forms and am stumped on how to proceed. I'm creating a forms.py with the aim that at the form level, a user can input a string query, and this query is then run against one of the models, depending on which one is selected from a drop-down on the form. Something like the following in HTML: <div class="row"> <form class="col s12"> <div class="row"> <div class="input-field col s6" > <input type="text" class="validate" list="option"> </div> <option value="1">model 1</option> <option value="2">model 2</option> <option value="3">model 3</option> </select> So essentially the query should be run against the appropriate model in views.py. Each model has its own view function. Also, how should I structure my urlconf to account for this? -
