django using an Integerfield for sorting
I have a model which has an IntegerField. this field may change after creation of object. I wanna use it for the "trend" part in my project, like those objects with the larger number must shown at top. so what is the best way (efficient) to do this. my current idea is: class Map(models.Model): rank = models.IntegerField() and later use it like this: sorted_list = Map.objects.order_by("-rank")[:50] is this a good idea even if there are many requests for the trend page? -
Users gets an Qr code with link to django webpage with login required
My problem: A user gets an email with qrcode, the qrcode links to a website. But when the user is not logged in he cant reach the linked site (because of the login requirement). When the the user is logged in there is no problem, after scanning the qr he gets to the site. How can i make it user friendly when the user is NOT logged in. User gets qrcode, scans it and gets the login page of django. After logging in i want him to direct to the qr link directly. Is that possible ? Normally i post code, hower in this case i dont have any because the login proces is the standard one of django, and the qr link is just a decoded http link. -

I have a form where user can create a team. But, somehow the form data never saved on the db after submission. The form page just refresh and return the form with the filled data. This happen to any form that I created for the project. I feel too confused as I tried every possible way I can think of, but to no avail. Any help could be appreciated.

Why is Django not finding static files on S3?
I followed this tutorial in order to make Django use S3 when loading static files https://www.caktusgroup.com/blog/2014/11/10/Using-Amazon-S3-to-store-your-Django-sites-static-and-media-files/ When I try to upload new media files through my webapp they get uploaded directly on S3. However, when I try to load static files in my html templates and I inspect the links, those are still linked to my local drive. Why is Django not looking at S3 for static files in my case? settings.py: AWS_ACCESS_KEY_ID = config('AWS_ACCESS_KEY_ID') AWS_SECRET_ACCESS_KEY = config('AWS_SECRET_ACCESS_KEY') AWS_STORAGE_BUCKET_NAME = config('AWS_STORAGE_BUCKET_NAME') AWS_S3_REGION_NAME= "eu-central-1" AWS_S3_CUSTOM_DOMAIN = f'{AWS_STORAGE_BUCKET_NAME}.s3-website.{AWS_S3_REGION_NAME}.amazonaws.com' STATICFILES_LOCATION = 'static' STATICFILES_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage' # STATICFILES_STORAGE = 'custom_storages.StaticStorage' MEDIAFILES_LOCATION = 'media' DEFAULT_FILE_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage' # DEFAULT_FILE_STORAGE = 'custom_storages.MediaStorage' AWS_LOCATION = 'static' AWS_S3_FILE_OVERWRITE = False AWS_S3_OBJECT_PARAMETERS = {'CacheControl': 'max-age=86400'} AWS_DEFAULT_ACL = 'public-read' navbar.html: {% load static %} ... <img src="{% static '/images/logo1.png' %}" > When I reload and inspect my webpage I still see <img src="/static/images/logo1.png"> instead of a link to AWS. -
Django nested serialization is not serializing on read
I know this issue is pretty popular but can't figure this out. class SpaceTypeSerializer(serializers.ModelSerializer): class Meta: model = SpaceType fields = ['id', 'company_id', 'label', 'value', 'active'] class SpaceSerializer(serializers.ModelSerializer): class Meta: model = Space # space_type = serializers.PrimaryKeyRelatedField( # queryset=SpaceType.objects.all()) space_type = SpaceTypeSerializer(read_only=True) fields = ['id', 'location_id', 'name', 'description', 'active', 'space_type', 'group_reservations_active', 'seats'] I'm getting just the id for the space_type field. I tried the commented out part and get the exact same result. class Space(Model): location = ForeignKey( Location, on_delete=DO_NOTHING, blank=False, null=False, related_name='spaces' ) name = CharField(max_length=255) description = TextField(null=True) active = BooleanField(default=True) space_type = ForeignKey( SpaceType, on_delete=DO_NOTHING, blank=True, null=True, related_name='spaces' ) Here's my model. Not sure what else to try but I want my space_type to have the entire space type object serialized. Here's my query: def get(self, request, pk, format=None): space = Space.objects.select_related('space_type').get(pk=pk) serializer = SpaceSerializer(space) return Response(serializer.data) Not sure if i need the select_related in there but putting it in for verification purposes. -

What are the methods for working with a self-referential model in a Django view?
I'm creating a virtual library in Django 3.1.5 and would like to show users books based on subjects that the books and users have in common. To make this a bit more powerful I plan on using a self-referential subject model. This will allow me to do a lot of things like suggest or show related books to users (e.g. I can show a user who's related to the subject Programming books that are relevant to Python, Django and Flask even though the user isn't related to those subjects directly), or create a dynamic library filter. Here are the subject fields that I have in my model: class SubjectType(models.Model): name = models.CharField(max_length=35) def __str__(self): return self.name class Subject(models.Model): name = models.CharField(max_length=255) subject_type = models.ForeignKey(SubjectType, on_delete=models.PROTECT) children = models.ManyToManyField("self", blank=True, related_name="parents", symmetrical=False) def __str__(self): return self.name My problem is that I'm fairly new to all of this, and while I've come across quite a bit of information regarding setting up self-referential models, I'm having a bit of trouble finding the right combination of QuerySet and view methods for efficiently querying such a model. And I would appreciate it if anyone could point me in the right direction. E.g.: How might I … -

I have a Model with a field: class SampleModel(models.Model): questions = models.ManyToManyField('questions.Question') 'Question' objects do have some simple foreign keys like Department or Organisation (with their corresponding 'name' fields). Could somebody point me a direction how to achieve the following: i'd like to have in Admin of "SampleModel" a way to filter these questions list by their related fields (department, organisation). I've seen some examples that should work for simple foreign keys, but nothing works for ManyToMany. Is there eventually any addon with similar funcionality? -

I get the warning that no route was found for path 'tribechat/1/'. git error message: Traceback (most recent call last): File "C:\Users\andri\AppData\Local\Programs\Python\Python39\lib\site-packages\channels\staticfiles.py", line 44, in __call__ return await self.application(scope, receive, send) File "C:\Users\andri\AppData\Local\Programs\Python\Python39\lib\site-packages\channels\routing.py", line 71, in __call__ return await application(scope, receive, send) File "C:\Users\andri\AppData\Local\Programs\Python\Python39\lib\site-packages\channels\security\websocket.py", line 37, in __call__ return await self.application(scope, send, receive) File "C:\Users\andri\AppData\Local\Programs\Python\Python39\lib\site-packages\channels\sessions.py", line 47, in __call__ return await self.inner(dict(scope, cookies=cookies), receive, send) File "C:\Users\andri\AppData\Local\Programs\Python\Python39\lib\site-packages\channels\sessions.py", line 254, in __call__ return await self.inner(wrapper.scope, receive, wrapper.send) File "C:\Users\andri\AppData\Local\Programs\Python\Python39\lib\site-packages\channels\auth.py", line 181, in __call__ return await super().__call__(scope, receive, send) File "C:\Users\andri\AppData\Local\Programs\Python\Python39\lib\site-packages\channels\middleware.py", line 26, in __call__ return await self.inner(scope, receive, send) File "C:\Users\andri\AppData\Local\Programs\Python\Python39\lib\site-packages\channels\routing.py", line 168, in __call__ raise ValueError("No route found for path %r." % path) ValueError: No route found for path 'tribe_chat/1/'.

Can't upload files larger than 2mb from Angular to Django rest framework
I want to be able to upload audio files of any size from an Angular website to Django backend. At the moment i am able to upload small files up to ~2mb without any problems, however, when uploading files larger than 2mb the Django function that handles the file upload doesn't fire, and no errors occur in Angular frontend. Angular uploadFile() { this.subscription = this.ApiService.uploadfile(this.fileToUpload,this.myControl.value).subscribe(data => { this.UtilsService.openSnackBar('Successfully added wavs',this.myControl.value) // do something, if upload success alert("success") }, error => { //console.log(error); alert("error") }); this.dialogRef.close(); } Upload function of ApiService, sends some parameters along with file(s) uploadfile(file,inst_label):Observable<any>{ const formData: FormData = new FormData(); for(let i = 0; i < file.length; i++){ if(i==0){ formData.append(inst_label,file[i],file[i].name) } else{ formData.append(i.toString(),file[i],file[i].name) } } return this.http.post(this.baseurl + '/upload_files', formData); } On my settings.py i have set: FILE_UPLOAD_MAX_MEMORY_SIZE = 5000000000 # 50 MB DATA_UPLOAD_MAX_MEMORY_SIZE = 5000000000 # 50 MB FILE_UPLOAD_PERMISSIONS = 0o644 Lastly my function upload_files in views.py prints something when files are less than 2mb, if the files are >2mb nothing happens. Hope i was clear enough, i'm running out of ideas on what to do besides cut those large files to smaller ones before uploading. -
Setting Default Image Dynamically Based On Model Choice - Django
Say I have a class: imageModel(models.Model): O1 = 'Option1' O2 = 'Option2' CHOICES = ( (O1, 'Option1'), (O2, 'Option2'), ) options = models.CharField(max_length=50, choices=CHOICES) image = models.ImageField() How would I dynamically set the default for the image field based on the option choice? I tried something like: imageModel(models.Model): O1 = 'Option1' O2 = 'Option2' CHOICES = ( (O1, 'Option1'), (O2, 'Option2'), ) options = models.CharField(max_length=50, choices=CHOICES) image = models.ImageField() def get_default_image(self): super().save() img = Image.open(self.company_logo.path) if self.options == "Option1": img.default = "/static/img/option1img.jpg" elif self.options == "Option2": img.default = "/static/img/option2img.jpg" img.save(self.image.path) But that didn't work. -
Send api request every x minutes and update context with status
I am trying to make a website, where user can start a task on a button click, which will send an api request every x seconds/minutes. Api request gets a list of offers as a response and the task will check if the api request is the same as before. If it is then then i want to show status on my page as: "No offers were found, still searching" and if the api response is different the status changes to: "I found an offer" I wanted to make that process in the background and without need to refresh the page by user. I want the context["status"] to be automatically updated when new offer is found. I tried to achieve this with threading but the page keep on loading as a task is working. Every idea is appreciated. Thanks!
