A news site: how to cope with images?
A news site. This is a sketch. Articles are going to be represented like this: article = forms.TextField() A template is only for the header, the footer and the sidebar. In the template there will be: {{ article | safe }} The article field will contain html. The editor will prepare an article in MS Word, and the front end specialist will prepare it for publication. The problem is: images may be inserted anywhere. Images will be with srcset like this: <img srcset="elva-fairy-320w.jpg 320w, elva-fairy-480w.jpg 480w, elva-fairy-800w.jpg 800w" sizes="(max-width: 320px) 280px, (max-width: 480px) 440px, 800px" src="elva-fairy-800w.jpg" alt="Elva dressed as a fairy"> Images will be prepared by django-imagekit. The problem is the paths to the images. As far as I can understand, paths to the images are only available in templates. I'm wholeheartedly against hard coding paths. Could you tell me whether there is any solution to this problem? -

Add a webcam snapshot as URL to from Django Using webcam.js
I need some help, to upload a snapshot taken from a webcam and attach the url to a form field (as a kind of profile picture) to then send the form and save everything using DJango. Im using webcam.js, but the way to upload is in php and i'm just starting with python so i'm confused to transform the code to python I got this code to take the snapshot. JS function configure(){ Webcam.set({ width: 320, height: 240, image_format: 'jpeg', jpeg_quality: 90 }); Webcam.attach( '#my_camera' ); } function take_snapshot() { // take snapshot and get image data Webcam.snap( function(data_uri) { // display results in page document.getElementById('results').innerHTML = '<img id="imageprev" src="'+data_uri+'"/>'; }); Webcam.reset(); } function saveSnap(){ var base64image = document.getElementById("imageprev").src; Webcam.upload( base64image, 'upload.php', function(code, text) { console.log('Save successfully'); }); } My idea is to put this on a Modal div so i could take the snapshot and then close the modal and when i close it, the URL of the snapshot will be placed in the form field, so i could submit it. I dunno if there is any other easy way or a lib from django to do this. greetings! -
Django URL appending to oneanother
I am having a problem understanding what is going on in Django. I created a delete function that supposedly deletes a record based on the DB record id. Upon deletion, I want to redirect to the same page I pressed the 'delete' button. However, when I look at the url in the browser, it now contains an appended version of the two views. I will show my code below for clarity: urls.py: url(r'entry/current/$', views.current_entry_list, name='current_entry_list'), url(r'^entry/create/$', views.create_entry_form_view, name='create_entry'), url(r'update/(?P<pk>\d+)/$', views.update_entry_view, name='update_entry'), url(r'delete/$', views.delete_entry_view, name='delete_entry'), View delete method: def delete_entry_view(request): if request.method == 'POST': id = request.POST['id'] Entry.objects.filter(id=id).delete() return redirect('entry/current/') View list records method: def current_entry_list(request): now = datetime.datetime.now() month = now.month current_entries = Entry.objects.filter(input_date__month=11).order_by('- input_date').all() for entry in current_entries: print(entry) paginator = Paginator(current_entries, 10) page = request.GET.get('page') try: current_entries = paginator.page(page) except PageNotAnInteger: current_entries = paginator.page(1) except EmptyPage: current_entries = paginator.page(paginator.num_pages) context = { 'current_entries': current_entries, 'current_month': month, } return render(request, 'finance/entry.html', context) Here is what my url in the browser looks like: 127.0.0.1:8000/finance/delete/entry/current/ Why does the redirected view url appends to the previous url? Is there anyway i can replace completely? -

DRF - request.user returns AnonymousUser in APIView while logged in during api call from fetch
I've constructed a APIView as such: class CustomAPIView(APIView): def get(self, request, *args, **kwargs): if not request.user or not request.user.is_authenticated(): return Response("User not logged in", status=status.HTTP_403_FORBIDDEN) # Other stuff And in my html template I'm making a call to it using fetchAPI: fetch('/api/request/url/', {method: 'get'}) .then( // Process info ); I'm logged in through all this, but I'm always being greeted with a 403 response with the request.user variable in the APIView returning AnonymousUser.

Django add value to hidden field inline formset

Django - Pass a variable from the Template to the Manager
I am building myself a little budgeting app. I am using this Manager: class AccountMonthlyManager(MonthlyCalculationManager): def transactions(self, date_str): date = get_this_month_and_year(date_str) entries = self.related_set().filter(date__month=date[0], date__year=date[1]).aggregate(total=Sum('amount')) return entries.get('amount', 0) along with this model: class Account(models.Model): begin = models.FloatField() weekly_change = models.FloatField() fixed_value = models.FloatField(null=True) income = models.BooleanField(default=False) monthly = AccountMonthlyManager() objects = models.Manager() I want to show the total from all the transactions for each account in the template kinda like this: {% for account in view.budget_accounts %} <tr class="dataLine budget" data-id="{{ account.id }}"> <td>{{ account.label }}</td> <td>{{ account.monthly.transactions }}</td> </tr> {% endfor %} However, the manager needs a the date string, which is in my url. http://localhost:8000/budgets/2017-12/ I'm looking for a way to accomplish this which doesn't involve me overloading my view with a lot of code for this single purpose. Right now, all I am doing is this: def budget_accounts(self): return Account.objects.filter(income=False, fixed_value=None) I need a way to get this url string back to the manager, so it can deliver the correct totals! -

Processing payment in dynamic form wizard
In django SessionWizard view how would I go about dynamically adding two forms, representing checkout and a receipt view, if the user chooses an option in the previous form that marks it is a paid item. I tried extending the form list in post but this causes nothing to be rendered. Moreover, since this is session based is this not insecure, even using braintree, since it's dealing with card numbers, paypal, etcetera. I would like to achieve a wizard, for a streamlined flow, of choosing a plan -> filling out form -> if paid -> checkout / receipt. -
Django dynamic verbose name

Is there an easier way of achieving a dynamic label though? Thanks! -
