Django - filtering by user
I want to render data from the Route model that belongs to the Driver in their 'accounts' page - so displaying the leave_from, destination etc data they have saved in the database so far. Models.py: class Driver(models.Model): user = models.OneToOneField(User, default=1) first_name = models.CharField(max_length=120, blank=True, null=True) last_name = models.CharField(max_length=120, blank=True, null=True) tel = models.CharField(max_length=120, blank=True, null=True) slug = models.SlugField(max_length=120, unique=True) timestamp = models.DateTimeField(auto_now_add=True, auto_now=False) updated = models.DateTimeField(auto_now_add=False, auto_now=True) def __str__(self): return self.user.username def get_absolute_url(self): return reverse("account", kwargs={"slug": self.slug}) def save(self, *args, **kwargs): self.slug = slugify(self.first_name) super(Driver, self).save(*args, **kwargs) class Route(models.Model): leave_from = models.CharField(max_length=120, blank=True, null=True) destination = models.CharField(max_length=120, blank=True, null=True) date = models.DateField(auto_now_add=False, auto_now=False) time = models.TimeField(auto_now_add=False, auto_now=False) driver = models.ForeignKey(Driver, on_delete=models.CASCADE) def __str__(self): return self.leave_from I've played with various querysets and the below is the closest to getting there (I think... I'm new to coding and Django). Views.py: def route(request, slug): routedetails = Driver.objects.filter(route=request.user.driver.route_set.all()) context = { "routedetails": routedetails, } return render(request, "route.html", context) With that I am able to get user to display the same number of instances of data in Route for that Driver.

Can't enable huey service on deploy server
I'm working in a Django project deployment. I have integrated huey to run asynchronous tasks. Locally all runs perfectly but now, at the deployment step, I'm getting troubles about huey service activation. I really can't find any information about that because I think that solution should be so simple, bat I really can't find it :(. I'm using nginx and gunicorn services.

Django Rest Framework: filtering using a method
I am using Django Rest Framework as a backend for an app. I have a User that has one Wallet. Then I have Item. If a User wants an Item it creates an instance in his/her Wallet called WalletItem. All works well. Now I want to limit the number of items for the User using an attribute limit_usage. First, I added a check to post method adding new instance that checks the number of item instances in User's Wallet. So the user gets 403 when trying to add third WalletItem if limit_usage == 2 for this Item. I would like to override a get_queryset() method or queryset in list()/retrieve() methods so that if anonymous user calls /items/ there are unfiltered items in response. However if the user is authenticated I would like to filter only those Items that s/he is allowed to put in the Wallet, i.e. those that have not exceeded limit_usage for current user. class Wallet(models.Model): user = models.OneToOneField('auth.User', related_name='wallet') class Item(models.Model): valid_from = models.DateTimeField() valid_to = models.DateTimeField() limit_usage = models.PositiveSmallIntegerField(default=0) class WalletItem(models.Model): wallet = models.ForeignKey('Wallet', related_name='%(class)ss') offer = models.ForeignKey('Item', related_name='offer') class ItemViewSet(viewsets.ReadOnlyModelViewSet): queryset = Item.objects.all().order_by('-created_at') serializer_class = ItemSerializer def list(self, request, *args, **kwargs): time_now = now() self.queryset … -
Django admin showing duplicate entries
I'm building an internal application tool with Django where I need to keep track of Point() objects. These objects are connected to Reservation model with custom through relationship. The problem Django seems to be duplicating some Waypoint objects in the admin list view. I think it's got something to do with ordering = ('reservationwaypoint__order',) since if I remove it, the count is correct. So to override I tried adding order_by() to distinct but it didn't work. Seems like order_by is not overriding ordering for some reason.. Admin PostgreSQL models.py class Waypoint(models.Model): class Meta: ordering = ('reservationwaypoint__order',) coords = models.PointField(geography=True) place_id = models.CharField(max_length=100) name = models.CharField(max_length=50) alias = models.CharField(max_length=30, blank=True) client = models.ForeignKey(Client) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) @property def get_alias(self): return '{} *'.format(self.alias) if self.alias else None def __str__(self): return self.name.encode('utf-8') def __repr__(self): return self.name.encode('utf-8') class Reservation(models.Model): # .. some other fields route = models.ManyToManyField( Waypoint, through='ReservationWaypoint', related_name='route', ) class ReservationWaypoint(models.Model): class Meta: ordering = ['order'] reservation = models.ForeignKey(Reservation) waypoint = models.ForeignKey(Waypoint) order = models.PositiveIntegerField(default=0) admin.py class WaypointAdmin(admin.ModelAdmin): list_display = ['id', 'name', 'alias', 'client', 'place_id'] list_filter = ('client',) def get_queryset(self, request): return super(WaypointAdmin, self).get_queryset(request).order_by().distinct() admin.site.register(Waypoint, WaypointAdmin) -

How to check if model has an attribute (OneToOneField) with queryset?
I am using the default User model with Agent acting as a OneToOne profile model. I want to create a queryset of all users who has Agent as a field. I'm aware of hasattr but it returns a True/False boolean value so I couldn't implement that into my query. views class AgentSearchResults(ListView): model = User template_name = 'agent_search_results.html' def get_queryset(self): queryset = super(AgentSearchResults, self).get_queryset() # Write something here to check if all users in 'queryset' has 'agent'. return queryset models for reference class Agent(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, related_name='agent') -
Access the filer plugin directly to link pages with thumbnails
I'm looking at creating a thumbnail based upon the first image which is placed on a page. I was thinking that the best way of doing this would be by accessing the filer plugin directly. The documentation isn't clear on how I can do this. Does anybody know? I know that I can access the Page Titles using: from cms.models import Title Title.objects.all() Is there a similar method for accessing the images on each page? -
Combining DRF unrelated models

Well yes. places is a foreignkey to user, user wouldn't have places only the reverse. How do I combine these two models? SomeUserModel works because it has onetoone with user, but it doesn't work with places. -

ConnectionError 111 in Django admin when hitting FB api
I'm making a custom django admin page that hits up our fb account in python requests to create a user using the fb test users and authenticate with our service. The function hits up: https://graph.facebook.com/v2.10/{}/accounts/test-users to create a new fb user and uses the access token returned in the response to authenticate with our service.

Django method in JavaScript causes TemplateSyntaxError
I am using ajax in javascript to send and receive database information that populate the html page. When I receive the data, I append it to the div elements. Every object I append should have a delete function. So I create a onclick method that passes along the unique id of that object My problem is that I can't seem to properly format the django url method with quotes for this call: onclick='removeFile("{% url 'delete_file' model['pk'] %}");' The full line look like this: $('#gallery tbody').append("<tr><td><a href='" + object['url'] + "'>" + object['file'] + "</a><span style='float:right'><button type='button' id='delete_button' class='btn btn-lg btn-danger' onclick='removeFile("{% url 'delete_file' model['pk'] %}");'></button></div></td></tr>") The error I get is a TemplateSyntax error Could not parse the remainder: '['pk']' from 'model['pk']' If I log the value of 'model['pk']' in the console, I get the correct ID. It loads correctly when I delete the onclick method (no delete function though). I have tried putting it in the html directly like this <button type="button" class="glyphicon glyphicon-remove-sign" onclick='removeFile("{% url 'delete_file' a.pk %}"); return false'> </button> where a is the model object from django and it works fine. How can I properly add the onclick method to the javascript append method? The full javascript … -

Zurb foundation Interchange with Django templates?
Is Zurb Foundation's Interchange compatible for use with Django templates? I can't see a way to get them to work together, though the issue is just a technical one - Interchange seems to want html file paths, while Django's html templates render inline. I suppose it would be possible to render the necessary templates each request into temporary files and hand those to Interchange, but that's not a very clean solution and would require a lot of boilerplate. I'm looking for a cleaner solution or for an alternative within Foundation and Django. -
