Celery django : launch worker - ImportError: No module named XXX
I have difficulties to laucnh celery worker. The exemple here works fine and is closed to documentation.

django.db.utils.IntegrityError: 1062, Duplicate entry for key
I have a problem with my django migrations. Before making the changes my table contained the following columns: STATUS = ( ('Active', 'Active'), ('Pending', 'Pending'), ('Incomplete', 'Incomplete') ) id = models.CharField(primary_key=True, max_length=50, unique=True, editable=False, default=uuid.uuid4) name = models.CharField(max_length=100, null=False, default='') country = models.CharField(max_length=100, choices=COUNTRY, null=True, blank=True) postcode = models.CharField(max_length=20, null=False, blank=True) address = models.TextField(max_length=200, null=False, blank=True) status = models.CharField(max_length=20, choices=STATUS, default='Pending') created_on = models.DateTimeField(default=timezone.now, editable=False) balance = models.DecimalField(default='0.00', max_digits=16, decimal_places=2, null=True, editable=True) but when I added the new fields: api_key = models.CharField(max_length=50, unique=True, editable=False, default=uuid.uuid4) key_exp = models.DateTimeField(default=one_day_hence, editable=False) I keep getting django.db.utils.IntegrityError: (1062, "Duplicate entry 'fc1d481d-add2-4d9c-92d9-a1b05018730a' for key 'api_key'") when running migrations. First of all, I find it suspicious since django will provide a different value for any default=uuid.uuid4. I tried migrating several times but I get the same error but with a different key. Secondly, I tried to remove unique=True but this didn't change anything, the error is the same. Any idea why and how I can solve this? -
Special symbol with context variable
In my django template I have: <strong>Copyright &copy; </strong> {{ copyright }} Where: copyright = "Company &copy; 2014-2018" Which shows: Copyright © Company &copy; 2014-2018 Why is the first symbol ok, and the second not? -
Django View Return Queryset with extra information
I have a normal Django view that returns the API for a query set. It takes query params from the URL and filters the database based on the parameters. It also outputs a maximum length of 3 "Part" objects. I would like to add something so that it returns information on whether the queryset is clipped by the maximum length of 3. The idea is that since the inputs the query parameters, if the parameters are too vague, then there will be too much data being queried from the database. So it is clipped but then the user needs to know that it was clipped. The current code looks like this class PartList(generics.ListAPIView): serializer_class = PartSerializer def get_queryset(self): """ Optionally restricts the returned purchases to a given user, by filtering against a `username` query parameter in the URL. """ queryset = Part.objects.all() querydict = self.request.query_params for (k, value) in querydict.items(): search_type = 'contains' filter = k + '__' + search_type queryset = queryset.filter(**{filter: value}) query_max_limit = 3 return queryset[:min(len(queryset), query_max_limit)] -
Django: any way to execute consecutive model.save() operations as 1 single DB request?
I have a function that does operations on a Django model instance, and I'm trying to break it up into sub operations that can be used independently. However, this means that I end up calling .save on each change and trigger a DB request. def subop1(instance): instance.a1 = 1 instance.save() def subop1(instance): instance.a2 = 2 instance.save() def subop1(instance): instance.a3 = 3 instance.save() def main_op(instance): subop1(instance) # triggers 1 DB request subop2(instance) # triggers 1 DB request subop3(instance) # triggers 1 DB request Is there any way to avoid having .save triggering a DB request every time while still keeping each function independently functional? Maybe some way of deferring the .save operations until some context manager exits and then saving all at once with 1 DB request. Tried to read through transaction documentation but I didn't find anything that fit. -

does django send_mail() support custom 'from'?
my django app is sending emails (via SendGrid API) using django.core.mail's send_mail send_mail( subject='foo', message=message, from_email=settings.DEFAULT_FROM_EMAIL, recipient_list=[user.email], fail_silently=False, html_message=rendered) the emails send fine but since it's sending from hi@myapp.com the email "From" alias in inboxes just shows up as "hi", and I'd like to make it more verbose so my recipients know who sent them the email ("Hi from AppName"). I don't see any field in send_mail docs (https://docs.djangoproject.com/en/2.1/topics/email/) for customizing how the "From" sender alias string appears (beyond the email itself) other than 'The “From:” header of the email will be the value of the SERVER_EMAIL setting'. does django's send_mail not support this (i.e., I need to rewrite this to using a sendgrid lib? https://github.com/sendgrid/sendgrid-python?) or is there a config setting in SendGrid where I can automatically set 'fromname'? thanks Is that -

Django REST Swagger hiding ModelViewSet with permission_classes=[IsAuthenticated]
I used Django REST Swagger in my Django project. It is able to show all the URL with views which does not have permission_classes = [IsAuthenticated]. While the view with permission_classes = [IsAuthenticated] is not shown in the list-api. Here is an example: class EquipmentCategoryViewSet(ResponseMixin, viewsets.ModelViewSet): queryset = EquipmentCategory.objects.all() serializer_class = EquipmentCategorySerializer permission_classes = [IsAuthenticated] if i remove permission_classes = [IsAuthenticated], it is shown in the swagger list-api. Please suggest what should be done to show views with isAuthenticated added. -

Django admin order field doesn't look right
My django admin panel doesn't seem to be sorting correctly, I have a custom method which will count the comments of each post. class PostAdmin(admin.ModelAdmin): list_display = ('title', 'author', 'comments', 'created') def get_queryset(self, request): qs = super(PostAdmin, self).get_queryset(request) qs = qs.annotate(com=models.Count('comment')) return qs def comments(self, obj): return obj.comment_set.count() comments.admin_order_field = 'com' But sadly, whenever I click the header of the table to sort by comments, I get something like this: 85 100 132 128 36 Yes, I've made sure to sort the column by descending order. What am I doing wrong? -
Django - How to add data from ajax button into html, so it updates everytime button is clicked?
currently I've got an ajax like button set up. The console shows that the like count is toggling when I press the button, but how do I actually retrieve the 'like_count' variable to put into my html. My button code is: <script type="text/javascript"> function toggleLike(){ $.ajax({ url: "{% url 'photo_blog-post_like_api' post.id %}", data: {like_count: 'like_count', 'csrfmiddlewaretoken': '{{ csrf_token }}'}, dataType: "json", success: function(data) { console.log(data); } }); }; </script> and the html for the button is: <input type="button" onclick="toggleLike()" value="Like"/> and the code for my view is: class LikePostAPI(APIView): authentication_classes = (authentication.SessionAuthentication,) permission_classes = (permissions.IsAuthenticated,) def get(self, request, slug=None, format=None, pk=None): obj = get_object_or_404(Post, id=pk) user = self.request.user updated = False liked = False if user.is_authenticated: if user in obj.likes.all(): liked = False obj.likes.remove(user) like_count = obj.likes.count() else: liked = True obj.likes.add(user) like_count = obj.likes.count() updated = True data = { "updated": updated, "liked": liked, "like_count": like_count } return Response(data) Thanks for the help!
