Django Access Formset Instances from within Forms
I'm building a website where students can answer multiple questions on an assignment. I have models to store these objects. I'm trying to create a formset of questions for an assignment. To do this, I'm using an inlineformset_factory to handle multiple questions. It is important the questions be created before the formset is submitted, and that the formset updates each question. My application has the following models: Models from django.db import models class Assignment(models.Model): name = models.CharField(max_length=255) class AssignmentSubmission(models.Model): """Can be completed multiple times by students.

Access to contents of the selected object in a Django OneToOneField
I would like to retrieve specific field data from a selected object within a OneToOneField relation. I have three models: Model1 contains the 'malfunction_1' field, which I intend to copy into the 'malfunction_3' field within Model3. Model2 possesses the OneToOneField. When a Model2 object is created and an object is chosen within the OneToOneField, another Model3 object should be generated. The content from 'malfunction_1' (Model1) and 'dynamik_2' (Model2) should then be duplicated into 'malfunction_3' and 'dynamik_3' fields, respectively. class Model1(models.Model): malfunction_1 = models.CharField(max_length=255, null=True, default=None) class Model2(models.Model): given_malfunctions = models.OneToOneField(Model1, blank=True, on_delete=models.CASCADE, default=None) dynamik_2 = models.CharField(max_length=255, default=None, blank=True) class Model3(models.Model): connection_to_model2 = models.ForeignKey(Model2, on_delete=models.CASCADE, default=None) malfunction_3 = models.CharField(max_length=255, null=True, default=None, blank=True) dynamik_3 = models.CharField(max_length=255, default=None, blank=True) would you use a receiver method or define a normal function for this use case? -
How to make django not duplicate custom class logs
I wrote MyClass which i'm using inside of DRF ViewSet "create" method. In this class i declared new logger with _set_logger method. The problem is that django duplicates MyClass logs, which I don't want: MyClass _set_logger method: import logging class MyClass: def _set_logger(self) -> None: self.log = logging.getLogger('logger_name') sh = logging.StreamHandler() sh.setLevel(logging.ERROR) formatter = logging.Formatter( "%(name)s | %(levelname)s | %(funcName)s | %(message)s" ) sh.setFormatter(formatter) self.log.addHandler(sh) The way i'm using MyClass in ViewSet "create" method: class SomeViewSet(ModelViewSet): def create(self, request, *args, **kwargs): obj = MyClass() obj.do_something(request) return super().create(request, *args, **kwargs) Logs: # my logs logger_name | funcName | CRITICAL | error_msg # django logs CRITICAL 2023-08-17 00:10:44,138 module_name 11 140294782023360 error_msg I tried changing logger_name to __name__ , expecting django and MyClass to use the same logger, but that didn't happen. class MyClass: def _set_logger(self) -> None: self.log = logging.getLogger(__name__) -
How to initialize Django database without using existing migrations?
I have a Django project, which contains dozens of migrations, and I want to initialize it on a new database. How do I do this without running all the migrations, which can take a lot of time to run? In earlier versions of Django, it used to have a "syncdb" command that you could run to create all tables in a blank database, bypassing all migrations. Current Django's migrate command has a --run-syncdb option, but the docs say: Creates tables for apps without migrations. Since all my apps have migrations, I interpret this to mean it does nothing in my case. Does modern Django no longer have anyway to initialize a database without tediously running through every single migration? Note, I'm not asking how to initialize a Django database. I'm asking how to do it more efficiently than by running migrations, which are designed to modify an existing database, not initialize one from scratch. -
Save generated image to model AND upload to S3?
I cannot find documentation on how to do what I need to do. My goal(s): User fills out a form with basic info Server-side a qr code is generated for that user. This qr code image needs to be uploaded to S3 to not bog down the server storage. This needs to be referenced in a model. WHY? This image will need to be displayed later in various front-end frameworks so at least the URL should be somewhere. It is stated lower but note: the s3 upload IS functional via form in admin. Currently I am building this out as an API to be used by various front-end frameworks so no forms in django will be used. All code is in testing mode so there is currently no security (just FYI). I am just trying to get this functionality working. Current model: from django.db import models # Customer model only class Customers(models.Model): customerId = models.CharField(max_length=25, unique=True) qr = models.FileField(upload_to='media/') #THIS IS WHERE IT WOULD BE STORED email = models.EmailField(unique=True) password = models.CharField(max_length=255) phone = models.CharField(max_length=20, unique=True) displayTag = models.CharField(max_length=255, unique=True) Views.py that is doing the saving from django.shortcuts import render from django.http import JsonResponse as j from qrewards_api_pj.helper import generate_id, … -
Django collectstatic ends up with "AWS S3 Boto3 Python - An error occurred (AccessDenied) when calling the DeleteObject operation: Access Denied"
I'm using Heroku+S3+Cloudfrong and I'm facing the titled error when trying to collectstatic. I'm having all the necessary IAM permissions, including AmazonS3FullAccess.

Why am I seeing an NGINX 502 error in Chrome, only on MacOS?
I have a very strange issue happening. Multiple users have reported it, across multiple computers, and multiple sites. They keep getting an NGINX 502 error. It only occurs on Google Chrome. It has only been reported from users using MacOS. I have not been able to recreate the issue I haven't found anything in logs, aside from I can see the access failure. The only commonality between the sites, is they have all been a Django/NGINX/Uwsgi stack on CentOS. The issue is not present if the user switches to incognito. The issue persists if the website cache is cleared. The issue disappears if the entire browser cache is cleared. One site is new, the other is old and has not had a configuration change since the problem began. The problem is sporadic, and seemingly random. First noted in the past ~1 month. Any thoughts on this would be helpful. Since I can't recreate the issue, I am having a hard time troubleshooting. Thanks in advance. -
Django Select2 field query return no select options
On a Django model, I have a foreign key field 'owner', refer to User model. I have a view class and form class for the model instance creation page. I made the form 'owner' field using select2 widget as below. All worked fine. class OwnerWidget(ModelSelect2Widget): search_fields = ["name__istartswith", "email__icontains",] Now I changed the page to use bootstrap modal. All other model fields behaved okay but not the 'owner' field: when I type in search characters like 'te', it start to send query to the server, but server returned 404 not found. See log below. "GET /select2/fields/auto.json?term=te&_type=query&q=te HTTP/1.1" 404 2699 I have nowhere configured the path '/select2/fields/auto.json'. I guess it's select2 default path. Did I miss anything on the view or form classes in order for this path to work? or I need to configure a different URL path somehow base on my view and form? I added line below to the widget, but no help. model = settings.AUTH_USER_MODEL I have no clue how this select2 search work. Any help appreciated. -

There is a problem for updating database using forms.form in Django and I want use only one 'update' button to update many database data
what I want do make is that show the existing data in the database to a user through HTML page. let a user update the existing data if he wants to do. Promblem 1> the problem is that,when running my code, a user input the new data and clicked 'update' button, but the update did not work. I don't know whether it is the reason or not, anyway, when I put 'def show_data' and 'def input' together, updating did work well. However 'def show_data'and 'def input' should be separate. 'def show_data' : it is for saving the data from excel file into the database using pandas 'def input': it is for receiving the input data from a user and updating the existing data with the input data Promblem 2> There are many 'update' button in the web page.

Wagtail custom permissions

I have then made various users members of this group. However these users still get a '403 forbidden' screen, it is only superusers that can access the relevant pages. What else do I need to do? -

I created the following models difficulty_choices=(('easy','easy'),('hard','hard'),('medium','medium')) class Quiz(models.Model): name=models.CharField(max_length=200) topic=models.CharField(max_length=100) number_of_questions=models.IntegerField() difficulty=models.CharField(max_length=100,choices=difficulty_choices) TimeLimit=models.IntegerField(blank=True) def get_questions(self): return self.questions_set.all()[:self.number_of_questions] class Questions(models.Model): text=models.CharField(max_length=200) quiz=models.ForeignKey(Quiz,on_delete=models.CASCADE) correct=models.CharField(max_length=25) def __str__(self): return str(self.text) def get_answers(self): return self.answers_set.all() class Answers(models.Model): text = models.CharField(max_length=200) question = models.ForeignKey(Questions, on_delete=models.CASCADE) def __str__(self): return f"Question: {self.question.text}, Answer: {self.text}" class UserAnswer(models.Model): quiz=models.ForeignKey(Quiz,on_delete=models.CASCADE) user = models.ForeignKey(User, on_delete=models.CASCADE) question = models.ForeignKey(Questions, on_delete=models.CASCADE) answer = models.ForeignKey(Answers, on_delete=models.CASCADE,null=True,blank=True) and forms.py is class QuizForm(forms.ModelForm): class Meta: model = Quiz fields = ['text'] exclude = ["text"] # Add other fields as needed selected_answer = forms.ChoiceField( label="", choices=[], # We'll update choices dynamically widget=forms.RadioSelect ) def __init__(self, *args, **kwargs): super(QuizForm, self).__init__(*args, **kwargs) quiz_instance = kwargs.get('instance') questions = quiz_instance.get_questions() answer_choices = [] for question in questions: answers = question.get_answers() answer_choices=[(answer.id, answer.text) for answer in answers] self.fields["selected_answer"] = forms.ChoiceField( label='select the correct option', choices=answer_choices, widget=forms.RadioSelect ) Here in forms I have used the for loop to iterate through each question … -

How to List Categories with Dropdown in Django
I would like to add a dropdown menu to my Django project that lists all categories from the database. The challenge I'm facing is that while I can get the categories listed on a single page (category), I would like them to be accessible throughout the entire website. I would really appreciate if someone helps. Thanks in advance. views.py #dropdown list of categories class CategoryListView(View): template_name = 'media/categories_dropdown.html' def get(self, request, *args, **kwargs): categories = Category.objects.all() return render(request, self.template_name, {'categories': categories}) urls.py path('category/', CategoryListView.as_view(), name='category-list'), media/categories_dropdown.html {% for category in categories %} <option value="{{ category.slug }}">{{ category.name }}</option> {% endfor %}
