Update using record with no pk in body using UpdateAPIView
I am trying to develop an update (PUT) endpoint that would not require adding pk to the url or body. The code below requires the currentbal_autorecharge entered as an id and it works. But i will like to update records without adding the pk to the body of request. I would prefer to use the token to get the current user and then use that to complete the update. i can successfully get the current user and current user id using the view below. How can i utilize this pk without entering it in the body? class CurrentBalance(models.Model, Main): currentbal_autorecharge = models.OneToOneField(User, on_delete=models.CASCADE, related_name='currentbal_autorecharge') currentbal_update = models.DecimalField(decimal_places=2, max_digits=10000, null=True) def __str__(self): return self.currentbal_autorecharge.phone class CurrentBalanceSerializer(serializers.ModelSerializer): class Meta: model = CurrentBalance fields = ( 'currentbal_autorecharge', 'currentbal_update' ) class CurrentBalanceUpdate(UpdateAPIView): authentication_classes = (TokenAuthentication,) permission_classes = (IsAuthenticated,) # queryset = CurrentBalance.objects.all() serializer_class = CurrentBalanceSerializer def update(self, request, *args, **kwargs): serializer = self.serializer_class(data=request.data) print(serializer) serializer.is_valid(raise_exception=True) serializer.save() return JsonResponse({"status": "success"}) -

'Authentication Unsuccessful' When Trying To Send Email Through Django
I've been trying to send emails using my Outlook email through Django but have been getting a variety of error messages, including (535, b'5.7.3 Authentication unsuccessful [SYBPR01CA0102.ausprd01.prod.outlook.com]') Apparently I need to allow SMTP AUTH, but cannot find how to do this as I am using Outlook in my browser and don't have it downloaded (it keeps requesting I pay for it, but I'd prefer not to as I really don't see the need for this small project, unless I need to). I did however pay for the email. I've also read that Outlook doesn't support smpt: Outlook 365 OAuth 535 5.7.3 Authentication unsuccessful My settings in Django are: DEFAULT_FROM_EMAIL = '###@###.###' EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' EMAIL_HOST = 'smtp-mail.outlook.com' EMAIL_PORT = 587 EMAIL_USE_TLS = True EMAIL_HOST_USER = '###@###.###' EMAIL_HOST_PASSWORD = '########' My question is can I send Outlook emails through Django? If so, what am I doing wrong? Thank you. -

(Django) How to create a verification mixin that references two models?
I have two classes Organisation, and Staff in addition to the User class. I want to create a mixin called "UserIsAdminMixin" that checks whether the user logged in has the role "admin" in a specific Organisation. The classes (simplified) class Organisation(models.Model): name = models.CharField(max_length=50) class Staff(models.Model): class Role(models.TextChoices): ADMIN = 'ADMIN', "Admin" STAFF = 'STAFF', "Staff" user = models.ForeignKey(settings.AUTH_USER_MODEL, null=True, blank=True, db_index=True, related_name="staff_profiles", on_delete=models.SET_NULL) organisation = models.ForeignKey('organisations.Organisation', db_index=True, related_name="staff", on_delete=models.CASCADE) role = models.CharField(max_length=10, choices=Role.choices, default=Role.STAFF) I then currently have this for my UserIsAdmin mixin: class UserIsAdminMixin: def dispatch(self, request, *args, **kwargs): if self.request.user.staff_profiles.filter(organisation=self.get_object(), role=Staff.Role.ADMIN): return super().dispatch(request, *args, **kwargs) else: raise PermissionDenied This works great for this view: organisations.views.py (URL: organisation/<int:pk>) class OrganisationDetail(LoginRequiredMixin, UserIsAdminMixin, generic.DetailView): model = Organisation template_name= "organisations/detail.html" login_url = "login" But I'd also like it to work for this view as well, which it obviously doesn't as self.get_object() returns a Staff object in this case when it's expecting an Organisation object: staff.views.py (URL: organisation/<int:pk_alt>/staff/<int:pk>) class StaffDetail(LoginRequiredMixin, UserIsAdminMixin, generic.DetailView): model = Staff template_name="staff/detail.html" login_url = "login" I was able to make changes to the mixin to get it to work in the second scenario but not the first: class UserIsAdminMixin: def dispatch(self, request, *args, **kwargs): if self.request.user.staff_profiles.filter(organisation__pk=self.kwargs['pk_alt']), role=Staff.Role.ADMIN): return … -
Why we need django-session?

Haystack + Solr + Django range faceting
I am using Django-Haystack with Solr(6x) backend in attempt to add faceted search to my application. I hit a problem, since I cannot find a way to implement range faceting. My query looks like this (looking at solr documentation): class FacetedProductSearchForm(FacetedSearchForm): def no_query_found(self): return SearchQuerySet().facet('price', range_filed='price', range_start=0, range_end=1000, range_gap=50, mincount=1, limit=10).all() My expectation of the results would be something like this: 0-50 (3) 50-100 (2) 100-150 (4) ... But what I get is still just a count of products not grouped in ranges but just a count of specific prices: 114 (2) 165 (3) 250 (3) ... *(sample values dont add together, this is just to demonstrate the point) In my template, I simply iterate over facets. {% if facets.fields.price %} <dt>Price</dt> {% for price in facets.fields.price|slice:":5" %} <dd> <a href="{{ request.get_full_path }}?selected_facets=price_exact:{{ price.0|urlencode }}">{{ price.0 }}</a> ({{ price.1 }}) </dd> {% endfor %} {% endif %} How can I implement range faceting in this scenario, using haystack and solr? -

I'm trying to create a social media news feed, with the posts, but I dont want to show the comments just if the user presses the button Show Comments. The problem is that when I press the button of one post, all the post will extend comments. I don't really know how to solve this... {% for post in posts %} <div class="container"> <div class="row"> <div class="[ col-xs-12 col-sm-offset-1 col-sm-5 ]"> <div class="[ panel panel-default ] panel-google-plus"> <div class="panel-heading"> <img class="[ img-circle pull-left ]" width="50" height="50" src="{{post.author.profile.image.url}}" alt="Mouse0270" /> <h3 class="author">{{post.author}}</h3> <h5><span>Shared publicly</span> - <span><a href="{% url 'post-detail' post.id %}"> {{post.date_posted}} </a></span> </h5><br> </div> <div class="panel-body"> {% if user == post.author %} <a class="text-right" href="{% url 'post-update' post.id %}"><p>Update</a> <a class="text-danger text-right" href="{% url 'post-delete' post.id %}">Delete post</a> {% endif %} <p>{{post.content}}</p> {% if post.image %} <img src ="{{post.image.url}}" width="300" height="300" border="0" class="img-thumbnail"> {% endif %} {% if post.video %} <video width="250" controls > <source src="{{post.video.url}}" type="video/mp4" > </video> {% endif %} </div> <br/> <div class="container" > <a href="{% url 'add-comment' post.id %}"><button class="btn btn-primary">Add comment</button></a> </div> <br> <button type="button" class="btn btn-danger btn-block" data-toggle="collapse" data-target="#demo">See comments</button> <div id="demo" class="collapse"> {% for comment in post.comments.all %} <div class="container"> <div class="row"> <div … -
Unique email verification to social-django
I have this webapp that has three login options (the normal method, google, facebook). The email is defined as unique, so I put this verification in the normal method, but I don't have that in the Facebook and gmail login methods, so when I log in to Google and try to log in to Facebook, it gives an error because it is the same email. I used AbstractUser to create a new user model. The error: How can i fix this? i want to show a error message on the login with the django messages if possible -
