Got AttributeError when attempting to get a value for field `author` on serializer `CommentViewSerializer`
Here is the serializers.py class CommentViewSerializer(serializers.ModelSerializer): author = UserViewSerializer() class Meta: model = Comment fields = ('author','content','article') def create(self, validated_data): return Comment.objects.create(**validated_data) Here is the models.py class Comment(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) article = models.ForeignKey(Article, on_delete=models.CASCADE, related_name='articlefda') author = models.ManyToManyField(User,unique=False, related_name='articsles') parent = models.ForeignKey('self', null=True, blank=True,on_delete=models.CASCADE, related_name='replies') content = models.CharField(max_length=100) timestamp = models.DateTimeField(auto_now=True) why do i keep getting the error?There is no typo or something. Got AttributeError when attempting to get a value for field `author` on serializer `CommentViewSerializer`. The serializer field might be named incorrectly and not match any attribute or key on the `User` instance. Original exception text was: 'User' object has no attribute 'author'. -
Django: Passing parameter to a URL pattern name inside views
In the example below, I'm trying to use the URL pattern name (ie, 'update_profile') instead of the absolute path (/profile/str:pk/update) in one of my views. This way if I later change my url path, I don't have to go an change each time I used the absolute path. My question: how do I pass 'pk' into a pattern name? I've tried things like: success_url = 'update_profile' % (pk) But that doesn't seem to work. urls.py path('/profile/<str:pk>/update', views.ProfileUpdateView.as_view(), name='update_profile'), views.py def submit_profile_form(request, pk): if request.method == "POST": success_url = 'update_profile' // <------ How do I pass 'pk' in here? ... return redirect(success_url) Thanks for your help! -

Wagtail set default page explorer view location for PageChooserBlock in admin
Way to browse pages from particular location in PageChooserBlock, like browse "sub pages or same level pages" from current editing page in which this block is used. I observed that when any page is selected in PageChooserBlock then browsing starts from the same current selected page. I wanted to start default browsing from current edting page (in which this PageChooserBlock block is used) if no page is already selected. Is there any way to do it? I googled for some way or direction for doing it but no success. I also checked chooser hook but there is no way to get current editing page in this hook. So can't use it. Also tried to search in source code of PageChooserBlock for such possibility but no success for me or may be I missed the possible way. Your help is appreciated. -

access Task attributes in comment CreateView(form) in Django
Good evening! I need a little help... Again :) I have two classes in my models.py (same app) Tasks and Comments, in order to create a comment I made a Class in views.py CreateView, is a built in form that django creates... Well when I send the user to comment_form to create a new comment I would like to have the task info in that page... Something like: {{user.username}} you're about to comment in {{task.title}} - {{task.content}} {{form}} The problem is that I can not access task.title, task.content and for that matters not even user.username variables in that form... I went through the docs and couldn't find a solution not even a clue on how to think to solve that. Models.py: class Task(models.Model): title = models.CharField(max_length=50) content = models.TextField(blank=True) date_created = models.DateTimeField(auto_now_add=True) due_date = models.DateTimeField(default=timezone.now) author = models.ForeignKey(User, null=True, on_delete=models.SET_NULL, default=User) responsable = models.ForeignKey(User, null=True, on_delete=models.SET_NULL, related_name="author", default=author) STATUS_CHOICES = [('D', 'Done'),('P','Doing'),('N','Not done')] Status = models.CharField(max_length=1,choices=STATUS_CHOICES, default='N') IMPORTANCE_CHOICES = [('H', 'High'),('M','Medium'),('L','Low')] importance = models.CharField(max_length=1,choices=IMPORTANCE_CHOICES, default='M') DEPARTAMENT_CHOICES = [('D', 'Dev'),('M','Marketing'),('H','HR'),('L','Legal'),('F','Finances'),('O','Others')] departament = models.CharField(max_length=1,choices=DEPARTAMENT_CHOICES, default='M') is_public = models.BooleanField(default=False) def __str__(self): return self.title def get_absolute_url(self): return reverse("task-detail", kwargs={"pk": self.pk}) class Comment(models.Model): task = models.ForeignKey(Task, on_delete=models.CASCADE, related_name='comments') author = models.ForeignKey(User, null=True, on_delete=models.SET_NULL, default=User) body … -
Paginating FormView
My goal is to create a mixin that would take care of paginating both ListView and FormView that has a list of FormSets in the template. While ListView part is mostly straight forward, I'm having hard times trying to paginate created formsets. Is there any clever way to include pagination inside generic views? All tips and any contribution will be highly appreciated! -

Serve multiple web requests in Django
I am using Django with Nginx and want to serve multiple requests in parallel. We have Docker configuration and one pod has 10 cores. I am trying to create multiple workers in uWSGI like (uwsgi --socket /tmp/main.sock --module main.wsgi --enable-threads --master --processes=10 --threads=1 --chmod-socket=666) Request first lands to view and from there it calls service file which does heavy work. Actually, I am using openCV library in service file which has loop over all pixels to remove colored ones(pretty time consuming..) I also tried using multiple cores and 1 worker as (uwsgi --socket /tmp/main.sock --module main.wsgi --enable-threads --master --processes=1 --threads=10 --chmod-socket=666). But still performance did not improve. I think it is due to GIL which is getting acquired while doing heavy I/O operations, not sure how I can find a work around it. Or use all cores in some other efficient way? TIA! -
Django Celery Beat for periodic task in Django with Celery is not working
I wanted to add celery to my django project. But somehow it does not seem to work as expected although I followed the steps in the official documentation. Here are the parts of my Django project: # celery.py import os from celery import Celery from celery.schedules import crontab os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'bookProjectSetting.settings') app = Celery('bookProjectSetting') app.config_from_object('django.conf:settings', namespace='CELERY') # Load task modules from all registered Django app configs. app.autodiscover_tasks() app.conf.beat_schedule = { 'update-lifetime': { 'task': 'tasks.update_life_time_of_books', 'schedule': crontab(minute='*/5'), }, } Then the init file: # __init__.py from .celery import app as celery_app __all__ = ('celery_app',) Now, in my app folder( called books), the tasks.py looks like follows: from books.models import Book from celery import shared_task @shared_task def update_life_time_of_books(): # Query all the books in our database print("Query all books.") books = Book.objects.all() # do sth. with books. for the sake of brevity I do not show this In my settings.py file I have this for celery: CELERY_BROKER_URL = 'redis://localhost:6379' CELERY_TIMEZONE = 'Europe/Berlin' # ... bla bla INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'django_celery_beat', 'rest_framework', 'books', ] I started the redis server in a second tab via the redis-server command so that it can take the part as a broker.

Python Executing SQL fails over due to non existing field in json data
I am getting some JSON data from a third party API. I am trying to add that data into my own database to be used for a website. I loop through each record in the JSON and execute a SQL query to insert that data into my database. However some records in the JSON data doesn't exist, and therefore causes my query to fail. I have set defaults for these fields for this reason however it still falls over. isNonFoilOnly field will only appear in some of of the records in the JSON data. models.py class Set(models.Model): code = models.CharField(max_length=100, unique=True) keyrune_code = models.CharField(max_length=100) name = models.CharField(max_length=100) type = models.CharField(max_length=100) release_date = models.DateField() base_set_size = models.IntegerField() total_set_size = models.IntegerField() is_online_only = models.BooleanField(default=False) is_non_foil_only = models.BooleanField(default=False) is_foil_only = models.BooleanField(default=False) sale_status = models.BooleanField(default=False) def __str__(self): return self.name views.py response = requests.request("GET", "https://mtgjson.com/api/v5/SetList.json") data = response.json()["data"] sorted_obj = sorted(data, key=lambda k: k['releaseDate'], reverse=False) sql = """ INSERT INTO dashboard_set (code, keyrune_code, name, type, release_date, base_set_size, total_set_size, is_online_only, is_non_foil_only, is_foil_only, sale_status) VALUES ( %s, %s, %s, %s, %s, %s, %s, %s, %s, %s, %s ) ON CONFLICT (code) DO UPDATE SET keyrune_code = %s, name = %s, type = %s, release_date = %s, base_set_size … -
Exists check takes forever in Django SQLite
I am running a webservice where a user sends a word as a request, and I use that word to filter entries in my database (the default Django SQLite). The relationship word-to-entry is one-to-one. That means there are two possible cases: The word exists in the database -> Return the associated Entry. The word doesn't exist -> Throw exception. The following lookup should then return a QuerySet with 1 or 0 objects: Entry.objects.filter(word__iexact=word) Expected Behavior: Cases 1 and 2 do not differ perceptibly in speed. Current Behavior: Case 1 takes at most half a second. Case 2 takes forever, around 1-2 minutes. I find this puzzling. If an existing word can be looked up regardless of where it is in the database, then why does case 2 take forever? I am not a django or database expert, so I feel like I'm missing something here. Is it worth just setting up a different type of database to see if that helps? Here is the relevant portion of my code. I'm defining a helper function that gets called from a view: mysite/myapp/utils.py from .models import Entry def get_entry(word): if Entry.objects.filter(word__iexact=word).exists(): entry = Entry.objects.filter( word__iexact=word ) # Case insensitive exact lookup return … -

ValueError could not convert string to float: ''
I'm having my app on heroku. I use timeme js to record user's active time spend on the page, and use a hidden form to store the value into the database. Additionally, I'm using otree package to write my app. The following is the code I use: models.py class Active(ExtraModel): active_duration = models.FloatField() active_record = models.LongStringField() views.py/pages.py in otree class intro_instructions(Page): def before_next_page(self): data = self.form.data p = self.player active = Active.objects.create(active_duration=data['active_duration'], active_record=data['active_record']) active.save() html <form method="post" role="form" id="form" autocomplete="off">{% csrf_token %} <input type="text" name="active_record" id="id_active_record" style="display: none" > <input type="number" step='any' name="active_duration" id="id_active_duration" style="display: none"> </form> The error ValueError could not convert string to float: '' { "csrfmiddlewaretoken": "vVhVRLrAUokmiNGRpzCaP78bnTOQyowf5VMfIDgKGglWGuEyQAU2wooWjQzXuBgD", "active_duration": "", "active_record": "" } Is it because active_duration is empty? Will it help if I set blank=true, null=true for the forms? I was assuming that every use would have value for the input. Also any ideas about why the input is empty? Could it be that the user used scripts to skip the page without visible fields? From the sentry error message, this happened to one user twice. -
Is it possible to use rows of one table as columns of other in django?
I am creating a quiz in Django where we add questions in one table and options in another table (using foreign key to link it to a question). I want to create a new table named Quiz which will store user input for each questions. I mean if I add four questions in Question table, having three Options objects each one, then quiz table has three columns which will store user input of each question. Quesions table : columns = ('id', 'question') rows = {(1, 'What is your name'), (2, 'Where do you live)} Choices table : Columns = ('id', 'choice', 'Question id(foreign key)') Rows = { ('1',"ram", QID-1,), ('2',"Sham", QID-1,), ('3',"India", QID-2,), ('4',"USA", QID-2,) } Quiz table (I want) : Columns = ('quizID', 'QID-1','QID-2') Rows = {('1', 'ChoiceID-1', 'ChoiceID-4'), ('2', 'ChoiceID-2', 'ChoiceID-4')} The idea is shown in the example...However, I don't find any other way than creating quiz columns manually for each question. I am trying to do this in Django. Kindly help me. or let me know if you have another idea to do the same thing. -
How to make a piece-by-piece decrease of an item from the cart

Django ManyToMany intermediary through table & constraints for product watchlists
I want to implement multiple "watchlists" that each user can add products into. A basic reproduction of the tables I currently have is as follows: class Product(models.Model): name = models.CharField(blank=False, null=False, unique=True, default=None, max_length=100) sku = models.CharField(blank=False, null=False, unique=True, default=None, max_length=100, verbose_name='Stock Keeping Unit') description = models.TextField(blank=True) price = models.FloatField(blank=True) class Profile(models.Model): user = models.OneToOneField(User, related_name='profile', on_delete=models.CASCADE) display_name = models.CharField(max_length=30) subscription = models.CharField(null=False, blank=False, choices=SubscriptionChoices.choices, default=SubscriptionChoices.SILVER, max_length=100) watchlists = models.ManyToManyField(Product, through='Watchlist') class Watchlist(models.Model): profile = models.ForeignKey(Profile, on_delete=models.CASCADE) product = models.ForeignKey(Product, on_delete=models.CASCADE) name = models.CharField(null=False, blank=False, max_length=20, default='WatchList1') As it can be seen above, I have chosen to use an intermediary 'through' table called Watchlist. I did so because I wanted to able to allow the user to rename the watchlist as they please, hence I included a field called name in the Watchlist table. I also have 3 levels of subscription that the user can have: Silver, Gold & Platinum. How do I do the following: Limit the number of watchlists to 2/5/10 depending on subscription level of user (2:Silver, 5: Gold etc). Limit the number of products in a watchlist to 10/20/30 again depending on subscription level of user. Add/remove products into a particular watchlist of a particular user. … -
Django Rest Framework: Serialize an Array in a multipart/form-data request
I am trying to send a List / array using multipart/form-data. The ModelSerializerdefines that field using class RequestSerializer(serializers.ModelSerializer): # ... in_categories = serializers.PrimaryKeyRelatedField(many=True, read_only=True) the Model field is defined as class Request(models.Model): # .... in_categories = models.ManyToManyField(to='Category', through='RequestToCategory', blank=False) now, I got a ModelViewSet defined as follows: class RequestViewSet(viewsets.ModelViewSet): # ... def create(self, request, *args, **kwargs): print(request.data) serializer = self.get_serializer(data=request.data) print(serializer.is_valid(raise_exception=True)) print(serializer.validated_data) However, the in_categories field never gets populated with actual data, nor does the validator raise an exception when called. I did not find any way to transmit the data in a way the field actually gets a list of keys as defined. I tried three things: Sending the data as literal resulting in request.data = <QueryDict: { ... 'in_categories': ['[2, 3]'] ... Sending the data as array resulting in request.data = <QueryDict: { ... 'in_categories[0]': ['2'], in_categories[1]': ['3'] ... Sending the data as array with extra key resulting in request.data = <QueryDict: { ... 'in_categories[0]id': ['2'], in_categories[1]id': ['3'] ... Each solution (i) arrives at the ViewSet, (ii) validates correctly but does (iii) not reflect into serializer.validated_data. Do I miss something? I spent already hours on this, finding no solution on how to make DRF understand what I want. -

Django multilanguage: language switcher does not respect prefix_default_language=False

Postgres optional array parameter in Django raw sql
So I've used this question to create optional parameters in my Django raw_sql snippet: select da.data_date, hll_union_agg(dau.users) users_union from sales_dailyaggregationusers dau join sales_dailyaggregation da ON da.id = dau.daily_aggregation_id where outlet_id in %(outlet_ids)s and currency = %(currency)s and (%(transaction_channels)s is NULL or transaction_channel in %(transaction_channels)s) and (%(transaction_types)s is NULL or transaction_types && %(transaction_types)s) However, Django gives the following error: django.db.utils.ProgrammingError: syntax error at or near "NULL" LINE 11: ... and (NULL is null or transaction_channel in NULL) So it looks like it's processing the entire query and deciding that it's badly formed (even though Postgres would optimize away the second half of the code). Is there a way around this? -
