Django loading image from url - ImageField objected has no attribute _committed
I am using Django 3.2 I am trying to programatically create a model Foo that contains an ImageField object, when passed an image URL. This is my code: image_content = ContentFile(requests.get(photo_url).content) # NOQA image = ImageField() # empty image data_dict = { 'image': image, 'date_taken': payload['date_taken'], 'title': payload['title'], 'caption': payload['caption'], 'date_added': payload['date_added'], 'is_public': False } foo = Foo.objects.create(**data_dict) # <- Barfs here foo.image.save(str(uuid4()), image_content) foo.save() # <- not sure if this save is necessary ... When the code snippet above is run, I get the following error: ImageField object does attribute _committed I know this question has been asked several times already - however, none of the accepted answers (from which my code is based) - actually works. I'm not sure if this is because the answers are old. My question therefore is this - how do I fix this error, so that I can load an image from a URL and dynamically create an object that has an ImageField - using the fetched image? -
Add columns in django model table postgres
I recently edited my table and had overriden the primary_key to a title attribute. I tried deleting all previous migrations and even so, the model id, which should be the pk by default, isn't so. Since then I've been trying to add a new column id to my appname_model table. Here the appname is courses and model-class is course (written in lowercase in reference to the tablename statement I just made) I've entered the following commands multiple times and none have managed to add the field id: ALTER TABLE courses_course ADD COLUMN id int constraint; I've tried several other variants of the same syntax from other stackoverflow questions but none have worked out so far. I also want to set id to the primary key in that table. -
Django raw sql %d for ID not working for integer parameters
I have this raw sql for my Django model: cursor.execute('SELECT crowdfunding_offering.offering_name FROM crowdfunding_offering WHERE crowdfunding_offering.id = %d ORDER BY crowdfunding_offering.id DESC LIMIT 1', (int(self.offering.id),)) Which does not work. I am receiving this error: Exception Value: near "%": syntax error Then I try to change %d to %s, only then it works. I thought %d are for number parameters and %s are for strings, but why is it not working for %d? Here is the table with the id clearly being an integer: -
Cannot assign "'1'": "Offers.state must be a "States" instance
I have read several answers to this same question, but none have worked for me. Here's my model: class States(models.Model): name = models.CharField(max_length=20) abrev = models.CharField(max_length=3) def __str__(self): return self.abrev class Offers(models.Model): *other fields* state = models.ForeignKey(States on_delete=models.PROTECT) so in views i am doing this: if request.method == 'POST': try: **other fields** state = States.objects.get(pk=request.POST['state']) Offers.objects.create(**other fields**, state=state) except Exception as e: print ("error in form") But am always getting the same Error Cannot assign "'1'": "Offers.state must be a "States" instance. And as you can see, i am passing an instance, not the id of the element. I use the id that comes from the form just to query the DB and find the instance with this: state = States.objects.get(pk=request.POST['state']) The form works just fine, and I tried to do it with forms.py and if form.is_valid(), but got the exact same result. am on: django 3.2.3 python 3.9.2 -
Django automatically appending csrftoken to cookies send by React Native request
I've got a React Native app that is making requests using axios to my django server. const axios = require("axios").create({ baseURL: BASE_URL, headers: { 'cookie': `credentials=abc123;`, 'X-Requested-With': 'my_custom_app', } }); On my Django app, I am printing out the cookies for the request. print(request.COOKIES) When I'm printing the cookies on my local instance of the backend, things look fine: Here's the output from my local instance: {'credentials': 'abc123'} But on my prod instance of the server, the output is different: {'csrftoken': 'B17DuZmxWPyuTAEdcldsJqZX0dsDct4k6nHLXYtRPiJQFEpBrSPIH5G7M6rty0FH,credentials=abc123'} This obviously gets read incorrectly by the server and it thinks that my credentials are not available in the cookie. I'm not sure what is going on here, or why this only happens on my production instance. -
Optimal way for letting user download big files in the server using Django
I am making a Django application for an experiment and it will offer the possibility to the user to be able to download really big image files to a specific directory in the server. I have a PoC of that working, where the user sees a button clicks on it and the process to download begins. I have put the download process inside views.py which means it occurs upon visiting a specified URL. The code responsible for the download part similar to the following: with open(loc, "wb") as f: response = s.get(pos, stream=True) total_length = response.headers.get('content-length') if total_length is None: f.write(response.content) else: dl = 0 total_length = int(total_length) for data in response.iter_content(chunk_size=4096): dl += len(data) f.write(data) The problem is that for some images which are > 500MB the process takes quite some time and there are several issues, like if the user closes the app, or clicks away then the process stops. How can I make it in such a way so the user visits that page and clicks that button and the download process begins on the background without binding the user to stay to that page. Also maybe creating another endpoint which could update the user about the … -

Handle/fix django.core.exceptions.SuspiciousFileOperation in unit testing Django (nosetests)
I want to write a test for a Managment command that reads a file and does something. Everything works as expected. And for clean organization of my test files (in this case I check whether the read CSV file has certain validations), I want to place the test CSV file under my_project/my_app/tests/files/test_me.csv. And, when I run the test, Django is throwing this error django.core.exceptions.SuspiciousFileOperation: The joined path (/code/my_project/my_app/test/files/test_me.csv) is located outside of the base path component (/code/media). Here is my test code, class CommandTestCase(TestCase): def test_command_load_client(self): """Happy path for load client from a CSV File""" call_command('my_command_that_does_some_csv_checks', os.path.join(BASE_DIR, "my_app/tests/files/test_me.csv"),) # self.assertEqual(some_assertions, 1) If I put this file under /code/media however, this error does not occur. But I do not want to store it under /code/media. How to solve this problem? Note: I come from a Rails background. -
Renaming a field on a Django queryset with group by

I already tried to add the following approaches, but they both returned the full date format instead return only the month id: "month_id": "2021-01-07T15:26:53.080136Z" .annotate(month_id=F('date_joined__month')) .values('qtd', 'month_id')) or .values('qtd', month_id=F('date_joined__month'))) -

Confusing field accessing on m2m field in a query set
I have a django project with several models. Two of this models are: class Attack(models.Model): spell = models.ForeignKey("Spell", models.CASCADE, null=True) attacker = models.ForeignKey("Ent", models.CASCADE, related_name='attacker') defender = models.ForeignKey("Ent", models.CASCADE, related_name='defender') defender_pts_before = models.IntegerField(default=0, blank=False, null=False) damage_caused = models.IntegerField(default=0, blank=False, null=False) and class Ent(models.Model): name = models.CharField(max_length=50, blank=False, null=False) raze = models.CharField(max_length=50, blank=False, null=False) damage = models.CharField(max_length=50, blank=False, null=False) weakness = models.CharField(max_length=50, blank=False, null=False) health = models.FloatField(default=100, blank=False, null=False) attacks = models.ManyToManyField('self', through=Attack, symmetrical=False, related_name='attacked_from') battles = models.ManyToManyField(Battle, through=BattleParticipant, related_name='battles_part') As you can see the Ent model has a m2m field to itself through the Attack model. This is for representing the attacks between ents. The attack model stores all the damage the attacker caused to the defender in the damage_caused field (which is calculated when the attack is saved). I need to know for each ent the total damage it has caused in all the attacks, so I built the following query: Ent.objects.all().annotate(dmg=Sum('attacks__attacker__damage_caused')) but this doesn't seems to work. It only seems to work the right way with this query: Ent.objects.all().annotate(dmg=Sum('attacks__defender__damage_caused')) Tests I've created some entries to check the query (a single attack from one ent to another) In [106]: e1, e2 = Ent.objects.all().annotate(dmg=Sum('attacks__attacker__damage_caused'))[:2] In [107]: e1, e2 Out[107]: (<Ent: … -
DJANGO - How to store Model data in another model by modifying the __init__ and save() methods, with a Test Driven development approach?
So, lets assume I have two models, my main model where I have the data that goes to my endpoint, and a second model that I'm using to store the changes made to a field of the main model. They're very simple, like this: Main Model: M class MyModel(TimeStampedModel, models.Model): """A simple model""" field_1 = models.CharField(max_length=255, null=True, blank=True) field_2 = models.CharField(max_length=255, null=True, blank=True) choice_field = models.CharField( max_length=32, choices=ChoiceModel.choices, default=None, null=True, blank=False ) And the storing Model: Class MyModelHistory(models.Model): choice_field_from = models.CharField(max_length=32, null=True, blank=False) choice_field_to = models.CharField(max_length=32, null=True, blank=False) changed_at = models.DateTimeField() Now, there are various ways to connect these two. To make it easier, I'm only intereseted in tracking the changes made to choice_field. We could do it with signals or by modifying the __init__ and save methods of MyModel. For my application, I have to do with the latter, so here's what I've got so far: def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) #import pdb; pdb.set_trace() if self.pk is None: self._old_choice = None else: self._old_choice = self.choice_field def save(self, *args, **kwargs): super().save(*args, **kwargs) if self._old_choice != self.choice_field: MyModelHistory.objects.create( choice_field_from=self._old_choice, choice_field_to=self.choice_field, changed_at=timezone.now(), ) I'm making the tests to make sure this approach works in all possible scenarios. For example, when you … -

Multiple values using GET method in my template? with django
I am trying to send info using GET method and the django paginator. I am using buttons to send the request and on my views display the corresponding list, that works fine.
