Django Social Auth pipline redirect and create
I have implemented Django Social Auth to signup and login using Facebook and Twitter. I was wondering how can I use piplines to specify an action to be done. For example, after creating the profile, I want to check if a field is empty and then redirect the user to another page to complete the profile as Facebook and Twitter don't give you the email address for example. Thank you -

last activity feature in Django not updating properly
I am trying to implement a lastActive feature but I don't know what values should the null and blank property have for the lastActive field in the User model. With this version of the code, the lastActive fields get a similar time as the created field, but after every login+logout the lastActive field doesn't get updated. Other than that, I am also getting the following error if I try python manage.py migrate, although makemigrations works fine: File "/Library/Python/2.7/site-packages/django/utils/dateparse.py", line 94, in parse_datetime match = datetime_re.match(value) TypeError: expected string or buffer Here's my models.py: class User(models.Model): userID = models.AutoField(primary_key = True) username = models.CharField(max_length = 30, unique = True) first_name = models.CharField(max_length = 30, blank = False) last_name = models.CharField(max_length = 30, blank = False) email = models.EmailField(blank = False, unique = True) password = models.CharField(max_length = 30) class_year = models.IntegerField(validators=[MinValueValidator(4),MaxValueValidator(4),]) created = models.DateTimeField(auto_now = True, editable = False) #this field actually doesn't get updated yet, please debug lastActive = models.DateTimeField(auto_now = True, editable = True) Here's my middleware.py: class LastActiveMiddleware(MiddlewareMixin): def process_response(self, request, response): if request.user.is_authenticated(): User.objects.filter(pk = request.user.pk).update(lastActive=timezone.now()) return response Here's my view.py: def signup(request): if request.method == 'POST': form = SignUpForm(request.POST) if form.is_valid(): form.signup(form, request) username = form.cleaned_data.get('email') … -
AWS broken pipe error when uploading files bigger than 1 MG
I am a django newbie, and I inherited a django back-end with little documentation. I am making a request to said server, which is hosted on AWS. To store the files in the request we use S3. I have found nothing on the django code that limits the size of the file uploads, and I suspect it may be AWS closing the connection because of file size. This is the code I use, and below the error I get whenever the total size of the files is over 1 MG: import requests json_dict = {'key_1':'value_1','video':video,'image':,image} requests.post('https://api.test.whatever.io/v1/register', json=dict_reg) video is a video file ('.mov','.avi','.mp4',etc) with base64 encoding, and image is an image file ('.jpg','.png') with base64 encoding.

Why the javascript fetch API changes the request from POST to OPTIONS?

Django makemessages not detecting translatable strings
In a package 'purchase', there is a file reports.py. In this package I'm generating some pdf-reports that sometimes I want to translate to the Czech language.

But no files are added. .././manage.py makemessages -l cs_CZ -v 2 processing file reports.py in . processing locale cs_CZ This is a snippet from the reports.py file: from django.utils.translation import ugettext as trans def purchase_order_report(purchase_order, language='en'): ... doc.add_text(trans('Items requested'), 'Heading2') ...

getting get_list to display the list on multiple rows instead of one
I'm struggling to get my templatetag to work. I believe it's the syntax or the way i'm calling app_filters. Forgive me i'm learning web application development so if my logic is off please correct me. My goal is to pass a collection of check boxes on one template to a new one filtered at a different level. I have an array in my view from my GET.getlist call below checkedlist = request.GET.getlist('report_id') reportlist = QvReportList.objects.filter(report_id__in= checkedlist, active = 1).values_list('report_name_sc',flat = True) print (checkedlist) print (reportlist) args = {'retreivecheckbox': checkedlist} return render(request,'accounts/requestaccess.html', args) When I print my array the console displays it correctly, this example is if there was two check boxes selected: ['88', '89'] <QuerySet ['Common Data Model Reconciliation Load', 'LEJR BPCI IV - ICS Baseline']> I've created the following templatetag called app_filters defined as: from django import template register = template.Library() @register.filter def get_list(querydict, itemToGet ): return querydict.getlist(itemToGet) Now i'm trying to get my template to display what's in my console but as individual rows/indexes dependent upon user selections. I'm told get_list will do that for me. I've also tried get_at_index. I.E. I want to see retreivecheckbox as 88 89 and not [88,89] Using the following template my app … -
How do I place a template variable within a template tag?
I'd like the form to submit not to the request.user, but the {{views.kwargs.username}}. I currently have the form action like so: <form enctype="multipart/form-data" method="POST" action="{% url 'profile:make_request' username=request.user %}"> This is a form belonging on user-b's page, filled out by user-a, and submitted to user-b. For username, I'd like to put in {{view.kwargs.username}}, but it does not work. What's the proper way of passing this into the action? -
creating a UserProfile in django
i'm trying to create a UserProfile that is connected to a specific User on creation, however it does not seem to create a UserProfile when i register a user. how come is that?

Best way to specify one of the existing ManyToMany through relationships?
I have these models for a database of a library: class Author(models.Model): ... class Task(models.Model): ... class BookTask(models.Model): book = models.ForeignKey(Book) author = models.ForeignKey(Author) task = models.ForeignKey(Task) class Book(models.Model): authors = models.ManyToManyField(Author, through='BookTask'...) Everything there works fine, but I would like to specify one of the existing BookTask relationships as the main one. Think of one book where 3 authors have worked in. I would like to assign all 3 to the book and then set 1 of them as the main one. I've tried this: class Book(models.Model): authors = models.ManyToManyField(Author, through='BookTask'...) author_main = models.ForeignKey(BookTask...) But then the generated admin webpage doesn't show the expected choice widget. Any ideas? -
CSS file not loading (Django, python)
Here's the code I have: In the HTML file: link rel="stylesheet" href={% static 'css.css' %}" (Of course there is <> around it but it wasn't loading here for some reason) In settings.py: STATICFILES_DIRS = (os.path.join(BASE_DIR, 'static'),) The css.css file is located in the static directory which is in the same directory as manage.py , So why isn't the css file loading? There is also a js file which doesn't seem to be loading either, and it's in the same directory as the CSS file and I'm loading it in with the same method as the CSS file. Also, my pc isn't currently connected to WiFi, in case it makes a difference. I'm working with localhost. -

Django form with spotipy not updating on Apache2
I've made a Django website with this form.py to populate a template html with a dropdown list with all my current spotify playlists: from django import forms import spotipy import spotipy.util as util def getplaylists(): #credentials CLIENT_ID='xxxxx' CLIENT_SECRET='xxxxx' USER='xxxxxx' # token krijgen token = util.oauth2.SpotifyClientCredentials(client_id=CLIENT_ID, client_secret=CLIENT_SECRET) cache_token = token.get_access_token() sp = spotipy.Spotify(cache_token) # playlists opvragen results = sp.user_playlists(USER,limit=50) namenlijst = [] idlijst = [] for i, item in enumerate(results['items']): namenlijst.append(item['name']) idlijst.append(item['id']) #samenvoegen dropdowndata = zip(idlijst, namenlijst) #dropdowndata = zip(namenlijst, idlijst) return dropdowndata class SpotiForm(forms.Form): LIJSTEN = getplaylists() lijstje = forms.ChoiceField(choices=LIJSTEN, required=True) I'm running two versions of this Django website on my VPS (with exactly the same code): A) a version on Apache2 (with mod_wsgi) B) a test version ('python ./manage.py runserver x.x.x.x:xxx') When I add or delete a playlist in Spotify the dropdown list in version A gets updated, but the dropdown list of version B does not. Can someone explain to me why this is happening? -
Angular 4 HTTP requests to Django Rest Framework
I'm having issues finding the answer anywhere to an issue I'm having related to the (I think) Authorization header in an HTTP request I'm sending from Angular 4 to the Django Rest Framework API I've created. Lets get down to it: In settings.py, I've made sure that both a permission class and authentication class have been made available. REST_FRAMEWORK = { 'DEFAULT_AUTHENTICATION_CLASSES': [ 'rest_framework.authentication.BasicAuthentication', ], 'DEFAULT_PERMISSION_CLASSES': [ 'rest_framework.permissions.IsAdminUser' ], In views.py, this is perhaps where my fault is since the console error I get when trying to send the request from Angular -> Rest API is that 'No 'Access-Control-Allow-Origin' header is present on the requested resource.' which is untrue since it does NOT complain about this when I remove the authentication need. class UserViewSet(viewsets.ModelViewSet): queryset = User.objects.all().order_by('-date_joined') serializer_class = UserSerializer permission_classes = (IsAdminUser, ) authentication_classes = (BasicAuthentication, ) def list(self, request): queryset = User.objects.all().order_by('-date_joined') serializer = UserSerializer(queryset, many=True, context={'request': request}) return Response(serializer.data, headers={'Access-Control-Allow-Origin': 'http://localhost:4200'}, status=200) The Angular dev server is running on localhost:4200 while django is left on its default of localhost:8000.

Class based view - get function is not being called
