Getting an "Integrity Error Exception Value: NOT NULL constraint failed" in my Django application
I keep getting an integrity error for a particular table on my database - the review table, whenever a user tries to review a selected movie. I have gone through my codes line by line but can't seem to find the error. Please help! I always get an "IntegrityError Exception Value:NOT NULL constraint failed: movieworld_review.review_number" whenever the user tries to review a movie.

python3 manage.py migrate gives error about field even when it is deleted from the model class
Every time I run python3 manage.py migrate I get the same error about one of the fields in the model class. Even after deleting the field, the same error occurs. This is what the model class looks like: class Events(models.Model): name = models.CharField(max_length=200, null=True) date = models.DateTimeField(editable=True, null=True) sport = models.CharField(max_length=200, null=True) location = models.CharField(max_length=200, null=True) description = models.CharField(max_length=200, null=True, blank=True) date_created = models.DateTimeField(auto_now_add=True) tags = models.ManyToManyField(Tag) num_seats = models.IntegerField(null=True, blank=True) creator = models.CharField(max_length=200, null=False) And this is what the error looks like: TypeError: int() argument must be a string, a bytes-like object or a real number, not 'IntegerField' The above exception was the direct cause of the following exception: Traceback (most recent call last): File "/Users/laithtahboub/Desktop/Programming/Django/events_project/manage.py", line 22, in <module> main() File "/Users/laithtahboub/Desktop/Programming/Django/events_project/manage.py", line 18, in main execute_from_command_line(sys.argv) File "/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/django/core/management/__init__.py", line 425, in execute_from_command_line utility.execute() File "/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/django/core/management/__init__.py", line 419, in execute self.fetch_command(subcommand).run_from_argv(self.argv) File "/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/django/core/management/base.py", line 373, in run_from_argv self.execute(*args, **cmd_options) File "/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/django/core/management/base.py", line 417, in execute output = self.handle(*args, **options) File "/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/django/core/management/base.py", line 90, in wrapped res = handle_func(*args, **kwargs) File "/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/django/core/management/commands/migrate.py", line 253, in handle post_migrate_state = executor.migrate( File "/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/django/db/migrations/executor.py", line 126, in migrate state = self._migrate_all_forwards(state, plan, full_plan, fake=fake, fake_initial=fake_initial) File "/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/django/db/migrations/executor.py", line 156, in _migrate_all_forwards state … -
Django Query many to many field count miscalculation
I am creating a Django Blog Website and I am stuck at one point finding the no of likes on a specific post. I have created a webpage where all the posts are displayed. Now the problem I am facing is the no of likes are getting calculated wrong. Post Model -> class Post(models.Model): user = models.ForeignKey(User, on_delete=models.PROTECT) title = models.CharField(max_length=255) description = models.CharField(max_length=1000,null=True) Tags = models.CharField(max_length = 255,null=True,blank=True) Created_date = models.DateTimeField(auto_now_add=True) Updated_date = models.DateTimeField(auto_now=True) category = models.ForeignKey(Category, on_delete=models.PROTECT) Likes = models.ManyToManyField(to=User, related_name='Post_likes') favourites = models.ManyToManyField(to=User,blank=True,related_name="favourite") def __str__(self): return self.title Query in Views.py file to fetch all the posts -> posts = Post.objects.select_related().prefetch_related('images_set').annotate(Count('comments_post')).annotate(Count('Likes')).all() Now when I see the post.Likes__count in template it shows wrong count of 6 for one specific post but when I use post.likes.count() it shows count of 3. for other posts they both show same result. I am unable to find out why it is happening. This is the result for that specific post -> {'post_id': 22, 'user_id': 1, 'title': 'wkjdfh', 'description': 'kjwdfn', 'Tags': '.,smdf,m', 'category': <Category: Shoes>, 'userName': 'admin', 'images': <QuerySet [<Images: Images object (10)>, <Images: Images object (11)>, <Images: Images object (12)>, <Images: Images object (13)>]>, 'comments_count': 6, 'likesCount': 6, 'actualLikeCount': 3} This is very … -
How to safely execute user-written code in the backend?
I'm trying to build a Django web application that allows users to write Python code and runs that in the backend, kinda like how an IDE would work. I'm just wondering, what security risks does this come with? I'm sure there are plenty, the user could literally do anything with that code, so what would be a good solution to safely do this? Would running it inside a Docker container be a good solution? -
Django Authentication Application
I've just started to the django and got a little lost in between various doumentations and outdated tutorials. What I want to achieve is to create a simple dashboard application that also contains some backend scripts to integrate various apis most of them are open API's like weather API's , calendar API's etc just for learning. But I need to create a login page for the application and current tutorials for the authentication mosule of django is a little bit cunfusing as it never gives me how to implemelent a login form to the auth backend. I need a little bir more simple documentation for that. Is there anyone able to help me on that. I know the question is not code related but still any help will be appriceated. Most of findings from my previous searches are outdated and implementing those methods are often causes errors like non-existent templates etc... Meanwhile I'll be also checking the offical documentation. Thank you. -
Hashicorp Vault - Django query from docker container
Good afternoon, I have a two docker containers, one running a django app and the other running Hashicorp Vault as I am starting to play with Vault in a dev environment. I am using HVAC from a django view to write a secret to the vault that is entered by a user to set up an integration to a REST API for a data pull. When I run the following from my host machine, it writes just fine. client_write = hvac.Client(url='http://127.0.0.1:8200', token='MY_TOKEN') client_write.is_authenticated() When I run the same from the Django container, it fails with: requests.exceptions.ConnectionError: HTTPConnectionPool(host='127.0.0.1', port=8200): Max retries exceeded with url: /v1/auth/token/lookup-self (Caused by NewConnectionError('<urllib3.connection.HTTPConnection object at 0x7f2a21990610>: Failed to establish a new connection: [Errno 111] Connection refused')) Django docker container is running on localhost:8000 & the vault is localhost:8200. I also have a front end written in VueJS running on localhost:8080 that has no trouble communicating back and forth with the django rest API (django-rest-framework). Is there something in vault that I need to list where the queries can come from? Thank you, I am very new to Vault and am struggling through it a bit. BCBB -
Why is django's forloop.counter0 confused by an adjacent loop?
I have a template that looks like this: <table> <tbody> {% for row in rows %} <tr> {% for column in row %} <td>{{ column }}</td> {% endfor %} <td><input type=checkbox name="checkbox_{{ forloop.counter0 }}"></td> </tr> {% endfor %} </tbody> </table> The checkboxe names in the table that get generated start with checkbox_1 instead of checkbox_0. If I remove the inner for loop however: <table> <tbody> {% for row in rows %} <tr> <td>Column 1</td> <td>Column 2</td> <td><input type=checkbox name="checkbox_{{ forloop.counter0 }}"></td> </tr> {% endfor %} </tbody> </table> They start with checkbox_0 as they should. The inner loop appears to be messing up the counter for the outer loop. I even tried to use the with tag, but that didn't seem to help: <table> <tbody> {% for row in rows %} {% with forloop.counter0 as outer_counter %} <tr> {% for column in row %} <td>{{ column }}</td> {% endfor %} <td><input type=checkbox name="checkbox_{{ outer_counter }}"></td> </tr> {% endwith %} {% endfor %} </tbody> </table> Any idea what might be going wrong? -

Django Python contact form saves file but doesn't send the email
I'm trying to set up a simple contact form with an optional file upload; I don't want the file to be attached to the email message, I simply want to save the file to /media. I'm using required=False in the form to not require a file. But still, some of my form validation or form processing logic is wrong; the code below works when I submit the contact form without a file and I get an email. But if I attach a file, the file is saved to media, but I don't get an email even though the contact form correctly renders thanks.html after form submission. No errors in the logs.

DRF: Using URL parameters to determine ordering on nested serializer fields
My question is whether there is a way to use filters given by the user in the URL to order a queryset using nested serializers using the nested fields.

DRF upload extracted zip files
I'm going to upload some files through my DRF API. This API receives a .zip file that has some .xlsx files in, and I extract its content in the API view. Then I send this data to the serializer, But I get this error: [ { "file_name": [ "The submitted data was not a file. Check the encoding type on the form." ] } ] This is how I'm extracting my .zip file before passing data to the serializer: def _get_serializer_initial_data(self): with ZipFile(self.request.FILES.get('file_name')) as input_zip: return [ { 'file_name': input_zip.open(_input_excel) } for _input_excel in input_zip.infolist() ] Then I send data to the serializer this way: initial_data = self._get_serializer_initial_data() serializer = self.get_serializer(data=initial_data, many=True) I checked the extracted files type in the serializer class and it's ZipExtFile, which seems to be unacceptable by DRF. Any help would be appreciated. -
