How to query database with conditional expression in Django?
I have three models: Business, Offers and OfferPlan: Business: class Business(models.Model): name_of_business = models.CharField(max_length=255) Offers: class Offers(models.Model): business = models.ForeignKey(Business, related_name="business_offer", on_delete=models.CASCADE) title = models.CharField(max_length=255) subtext = models.CharField(max_length=255) OfferPlan: class OfferPlan(models.Model): WEEKDAYS = [ (1, _("Monday")), (2, _("Tuesday")), (3, _("Wednesday")), (4, _("Thursday")), (5, _("Friday")), (6, _("Saturday")), (7, _("Sunday")), ] offer = models.ForeignKey(Offers, related_name="business_offer_plan", on_delete=models.CASCADE) weekday = models.IntegerField( choices=WEEKDAYS, ) from_hour = models.TimeField() to_hour = models.TimeField() I have a ListView which search for businesses open based on different params such as city, category etc. I also want to now search by weekday, say which business is open on Monday will be displayed and which are not wont be displayed on that day. Weekday information is stored in OfferPlan and there could be multiple timings for the offers that day in OfferPlan table, but I want to query (filter, exclude) the businesses who has even a single entry on that weekday number. Here is my ListView: class SearchListView(ListView): template_name = 'search/search.html' model = Business def get_queryset(self): # queryset = Business.objects.filter(business_address__city=AppLocations.objects.first().city) if 'city' in self.request.GET: queryset = Business.objects.filter(business_address__city=self.request.GET.get('city')) if 'category' in self.request.GET: queryset = queryset.filter(category__code=self.request.GET.get('category')) # if 'date' not in self.request.GET: # queryset = B raise return queryset How could this be possible? … -
User Authentication in Django REST Framework
I have a Django REST backend, and it has a /users endpoint where I can add new users through POST method from frontend. /users endpoint url: http://192.168.201.211:8024/users/ In this endpoint I can view all users information and add new user, so I must avoid others entry it except Administrator. I create a superuser admin with password admin123 by python manage.py createsuperuser. My question is, If I want to do a HTTP POST from frontend(I use Angular) I have to pass the Administrator's user name and password, admin and admin123, along with POST head information. So I let others know the user name and password who check the source code of frontend. Is there any other way to do this Authentication without exposing Administrator's user name and password to others? -
400 ERROR (all-auth facebook) - Django
I'm using all-auth and Django RESTful Framework for authorization. I could receive token from Facebook from My Login page (login was successful with facebook id and password, ). Then I passed the token to the all-auth server (/rest-auth/facebook/). Here is the HTTP body { "access-token" : "TOKEN_FROM_FACEBOOK" } Then it printed 400 with "Incorrect value" (I got 400 so tested on Postman) { "non_field_errors": [ "Incorrect value" ] } I'm not sure which part of code I should post here. So can I comment back and edit this post once you ask? Thank you so much!:) -
Django - pre-save VS post-save VS view save
I want to perform some action (sending email) after updating an (already existing) object. In order to do it I need to compare values of the object before and after saving and only if something specific has changed - do that action. From reading other related question I understood that I can only do it in pre-save signal, since I can't get the old version inside 'post-save', but - what if there will be some issue with saving and the item will not be saved? I don't want to perform the action in that case. So I thought about implementing it somehow by overriding the view save, but I'm not sure that's the correct way to do it. What do you think? This is implementing in pre-save: @staticmethod @receiver(pre_save, sender=Item) # check if there is change that requires sending email notification. def send_email_notification_if_needed(sender, instance, raw, *args, **kwargs): try: # if item just created - don't do anything pre_save_item_obj = sender.objects.get(pk=instance.pk) except sender.DoesNotExist: pass # Object is new, so field hasn't technically changed else: # check if state changed to Void if pre_save_item_obj.state_id != VOID and instance.state_id == VOID: content = {"item_name": instance.title, "item_description": instance.description} EmailNotificationService().send_email("item_update" ["myemail@gmail.com"], str(instance.container.id) + str(instance.id) + … -
ManyToManyField already populated with users
I have a table called Story with a ManyToManyField to the User table. This is meant for user to subscribe. But when I check the admin/panel. The ManyToManyField is already populated with all users. And I can not change anything on this field. Also when I try to query all Stories I get no results. view: stories = Story.objects.filter(users=request.user) This is how I subscribe a user to a story: story = get_object_or_404(Story, pk=story_id) user = request.user story.users.add(user) This is the Story model: class Story(models.Model): story_name = models.CharField(max_length=550) users = models.ManyToManyField(User, related_name='subscriber') dateAdded = models.DateTimeField(auto_now_add=True) userAdded = models.ForeignKey(User) -
Django Rest Framework - Cache 'list' function but not 'retrieve' function (detail) in ModelViewSet

django rest framework - You cannot access body
I'm using django 1.8 rest api as below. @api_view(['GET', 'POST']) @authentication_classes((TokenAuthentication, SessionAuthentication, BasicAuthentication)) @permission_classes((IsAuthenticated,)) @staff_member_required def api(request): print request.data The problem with this is that it retrieves all parameters as string so I have to convert numbers and boolean manually. I tried using: print json.loads(request.body) but apparently django rest framework reads from the data stream which causes this error: Error: RawPostDataException: You cannot access body after reading from request's data stream I also tried json.loads(request.stream.body) because the documentation says stream should work. Is there a way I can retrieve the request post data with the appropriate types? Note that I'm using ajax to send the data with JSON.stringify. -

What is the recommended way to handle multiple api calls from angular to backend server on the same page(=angular component)?
I'm a backend developing using python/django stack to build a backend api server for our team's frontend developer, who uses angular2 to build SPA for our service. There are times when frontend need to make GET api call to two or more separate resources to backend server. For example, we have payments page, which needs information both from users and products tables. Is it better to make two separate calls at endpoints as follows: /api/users/:user_id /api/products/:product_id or it better to make backend django server to do some data processing to mix up the information and return the results containing both user-related info and product-related info at a single endpoint as follows: /api/payments/:payment_id Which do you think is more standard de facto? -

Django - using a form from another app - issue creating a redirect
I have a contact app in my project. To use the contact form from that app in the home page I created this in my views.py: from django.views import generic from contact.forms import ContactForm class HomePage(generic.TemplateView): template_name = "home.html" def get_context_data(self, *args, **kwargs): context=super(HomePage, self).get_context_data(*args, **kwargs) context['form'] = ContactForm return context When I submit the form on the home page it redirects to a blank page, instead of either the home page, or a thank you page.

Django Rest Framework(DRF) Json Web Token(JWT) Authentication and Login Process
I want to implement JWT authentication for my project since this seems to be the most simple one out of all the authentication procedures - but I don't quite understand how an User can actually login using the JWT-auth. It would be helpful if anyone could share some reading materials or provide some insights on the workflow of the login of an user using JWT. My own thoughts were somewhat along these lines: The frontend sends a obtain_jwt request to the backend via drf api The api returns a token in json format, if username and password were provided It's from here I don't understand what needs to done going forward. Does the backend need to do anything else to complete the authentication/login process? Do I need to do anything else with DRF Permissions? If this completes the login process, then there is something else which bugs me. For example, I have an APIView LoginView which has a post method to handle the login process. Now, does the frontend need to call the obtain_jwt function to get the function and then do another post-method to the LoginView? Or is there a way to return the json-web-token from that LoginView?

Here is my code: <!-- Individual items in the navbar --> <div class="collapse navbar-collapse" id="topNavBar"> <!-- This makes the collapse three bar button work --> <ul class="nav navbar-nav"> <li class="active"> <a href="{% url 'pics:index' %}"> <span class="glyphicon glyphicon-folder-open" aria-hidden="true"></span>&nbsp; Folders </a> </li> <li class=""> <a href="#"> <span class="glyphicon glyphicon-picture" aria-hidden="true"></span>&nbsp; Pictures </a> </li </ul> <form class="navbar-form navbar-left" role="search" method="get" action="#"> <div class="form-group"> <input type="text" class="form-control" name="q" value=""> </div> <button type="submit" class="btn btn-default">Search</button> </form> <ul class="nav navbar-nav navbar-right"> <li class=""> <a href="#"> <span class="glyphicon glyphicon-plus" aria-hidden="true"></span>&nbsp; Add Folder </a> </li> <li class=""> <a href="#"> <span class="glyphicon glyphicon-off" aria-hidden="true"></span>&nbsp; Logout </a> </li> </ul> </div> This should work, and the "Add Folder" and "Logout" buttons should be to the right, but it does not work, and these buttons are right next to the search bar. Any help would be appreciated!
