How to Upload an Image to Django
I have spent over three days on this. It appears that something saved to the db, but when I try to access it in the template, I can only get the object of the db. I can not access it. I believe it was not saved successfully because I don't see a media folder where it would be saved.

Conditionally do not allow a form submission
I have a template rendering 2 formsets. The user should only complete one of the 2 formsets. If the user completes both or neither of the formsets, I do not want the user to be able to submit the template form so the formsets do not clear out. Is this best handled at the template level?

Mimicking post request on django
I have a html page that sends a POST request to another site, and it works well. <form method = "POST"> ------form datas------ </form> Now I'm trying to simulate the same POST request with only django views, utilizing request module. I've checked the POST request header I send and duplicated it into my view function, And following is how I've coded. def POST_send(request): headers = {} headers["HOST"] = "my_server_domain" headers["Accept"] = "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9" headers["Accept-Encoding"] = "gzip, deflate" headers["Cache-Control"] = "max-age=0" headers["Connection"] = "keep-alive" headers["Content-Type"] = "multipart/form-data; boundary=----WebKitFormBoundarypoNblPUprPs3iWxh" headers["ORIGIN"] = "http://example.com" headers["referer"] = "http://example.com/sender_view/" form_data = {} ------form dats------ response = requests.post(target_url, data=form_data, headers=headers) content = response.content I expected this to be effective just as the original form's POST request, but I only get 404 not found error code.

AWS Beanstalk with Django: eb create complains about unknown config setting 'StaticFile'
I'm trying to deploy a django app with Elasticbeanstalk, following this setup https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/create-deploy-python-django.html and this https://www.1strategy.com/blog/2017/05/23/tutorial-django-elastic-beanstalk/ At the first attempt, in the .ebextension/django.config, I have option_settings: "aws:elasticbeanstalk:application:environment": DJANGO_SETTINGS_MODULE: "my_django_path_name.settings" PYTHONPATH: "$PYTHONPATH" "aws:elasticbeanstalk:container:python": WSGIPath: "my_django_path_name/wsgi.py" StaticFiles: "/static/=www/static/" when calling eb create, it complains about ERROR: ServiceError - Configuration validation exception: Invalid option specification (Namespace: 'aws:elasticbeanstalk:container:python', OptionName: 'StaticFiles'): Unknown configuration setting. So I took out the StaticFiles part, and eventually it becomes option_settings: "aws:elasticbeanstalk:container:python": WSGIPath: "my_django_path_name/wsgi.py" and it STILL complains about the unknown OptionName: StaticFiles Then I used the example in https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/create-deploy-python-container.html#python-namespaces with minor tweaking option_settings: aws:elasticbeanstalk:application:environment: DJANGO_SETTINGS_MODULE: production.settings aws:elasticbeanstalk:container:python: WSGIPath: ebdjango.wsgi:application NumProcesses: 3 NumThreads: 20 yet it STILL complains about the same thing. I don't know where the StaticFiles option name is being read. It doesn't exist in the .config file. Is it cached somewhere or something? -

What models and fields do I need to handle subscriptions such as Apple's Autorenewable Subscriptions?
I want to build an autorenewable subscription service, with an introductory trial period. There doesn't seem to be much written documentation on what models and fields I need to best model (and futureproof) my subscriptions. I'm starting with Apple's App store right now, but I do have a web interface and want to go to the Play Store at some point. From this video: https://developer.apple.com/videos/play/wwdc2018/705/ it seems like the minimum I need is something like a Subscription model with fields userId, productId, originalTransactionId, latestExpiresDate, consumedProductId, latestReceiptData. Is there anything else I need? Will I be able to retrieve other subscription information in the future (i.e. the billingRetry information as suggested in the video for grace periods; my understanding is by sending the saved receipt data I can get the JSON blob again and retrieve additional fields if I need to)? How will I extend this to co-exist with web and Play Store subscriptions? -
When is it required to use `schema_editor.connection.alias` in a django `migrations.RunPython` method?
When is it required to use schema_editor.connection.alias in a migrations.RunPython method and why? When using RunPython in a data migration, django advises that you should use schema_editor.connection.alias: from django.db import migrations def forwards_func(apps, schema_editor): # We get the model from the versioned app registry; # if we directly import it, it'll be the wrong version Country = apps.get_model("myapp", "Country") db_alias = schema_editor.connection.alias Country.objects.using(db_alias).bulk_create([ Country(name="USA", code="us"), Country(name="France", code="fr"), ]) class Migration(migrations.Migration): dependencies = [] operations = [ migrations.RunPython(forwards_func, reverse_func), ] Warning RunPython does not magically alter the connection of the models for you; any model methods you call will go to the default database unless you give them the current database alias (available from schema_editor.connection.alias, where schema_editor is the second argument to your function).* But the docs section that describes data migrations, it doesn't mention the alias at all: from django.db import migrations def combine_names(apps, schema_editor): # We can't import the Person model directly as it may be a newer # version than this migration expects. We use the historical version. Person = apps.get_model('yourappname', 'Person') for person in Person.objects.all(): person.name = '%s %s' % (person.first_name, person.last_name) person.save() class Migration(migrations.Migration): dependencies = [ ('yourappname', '0001_initial'), ] operations = [ migrations.RunPython(combine_names), ] -
Django how to optimize handling of large data?
I am working on a website where I want to populate product data from an external API. This api has hundreds of products data, and each product has dozens of variants. Each product and data have their images which I'm using Django's ImageField from models to store locally in Postgresql. Now the problem is that there are well over 15000 images, and it is taking forever to do populate the images data. Here is the structure of API: { ... Single Product Image: ... { Product Variant1: ..., [images] } { Product Variant2: ..., [images] } { Product Variant3: ..., [images] } } Each product has somewhere from 10-50 variations. Here is what I have done. For variation images, I'm using a many-to-one relationship table to store all the images of each variant: models.py: class ProductsVariation(models.Model): .... class VariationImages(models.Model): prd_id = models.ForeignKey(ProductsVariation, on_delete=models.CASCADE) img = models.ImageField( upload_to=settings.MEDIA_ROOT + 'product_variation') get_products.py: from msilib.schema import File from tempfile import NamedTemporaryFile from pip._vendor import requests for product in api_data: #Loop over main product ... main_product_request = requests.get(product['IMAGE_NAME']) main_img_temp = NamedTemporaryFile(delete=True) main_img_temp.write(main_product_request.content) main_img_temp.flush() main_product.prd_img.save(product['GENERIC_NAME'] + ".jpg", File(main_img_temp), save=True) main_product.save() # Populate this product's variants for variants in product['Product']: # Loop through each variant of … -

Can I filter options automatically on the Django Admin "add" page?
Consider a Word-A-Day Django webapp that presents the user with a vocabulary word each day, with the difficulty of the word increasing from "common" on Monday to "obscure" on Friday. The models in models.py look like this: class WordADay(models.Model): """A vocabulary word and its assigned day""" date = models.DateField( help_text="The date to post the selected word" ) word = models.ForeignKey( Words, help_text="The selected vocabulary word" ) class Word(models.Model): """Vocabulary words""" OBSCURITY_CHOICES = [(1,'Monday'), (2,'Tuesday'), (3,'Wednesday'), (4,'Thursday'), (5,'Friday')] word = models.CharField( max_length=32, help_text="A vocabulary word" ) difficulty = models.PositiveSmallIntegerField( choices=OBSCURITY_CHOICES, help_text="How obscure the word is" ) On the Admin "add" page for the WordADay model, I want to be able to first select a day from the standard calendar selector for the 'date' field. Once selected, I'd like the options in the drop-down selector for the 'word' field to be automatically filtered to only those instances of the Word model that have the correct difficulty, with "1" corresponding to a Monday date and "5" corresponding to a Friday date. That is, I'd like to filter Foreign Key options according to the value selected for a different field. For the sake of discussion, I can provide a skeleton admin.py from django.contrib import … -
Advice on User License Data Model and Integrating Django Permissions
I'm looking for some advice/feedback on a conceptual data model used in a Django web application that requires all users who signup have an available license for their email domain as I don't have much experience with data modeling. I'm also seeking advice on implementing and integrating some sort of permissions system where users who register under a certain license have limited access to certain features in the application. For a bit more context I'll provide a signup scenario. On my end, I've created an Organization (Example Org) along side a License (Example Org License) as well as two Domain Licenses (one with the domain example.org and another with sub.example.org) each with 1 allocated and available licenses. If Alice from Example Org registers with her company email alice@example.org and we have allocated a license for that domain, then Alice will have successfully signed up and the number of available licenses for that domain license will be 0. If Bob (also from Example Org) has an email bob@sub.example.org, and we have allocated enough licenses for Example Org for that domain, then Bob also successfully signs up and the available licenses for that domain license becomes 0.

Any advice? class UploadModel(models.Model): owner = models.ForeignKey(User, related_name="upload_models", on_delete=models.CASCADE) cord_y = models.IntegerField() cord_x = models.IntegerField() model = models.FileField(upload_to='standard//', validators=[validate_file_extension]) title = models.CharField(max_length=30) def __str__(self): return self.title def upload(request): if request.method == "POST": form = UploadModelForm(request.POST, request.FILES) if form.is_valid(): obj = form.save(commit=False) obj.owner = request.user obj.save() os.rename(BASE_DIR+'//media//'+str(obj.model),\ os.path.join(BASE_DIR, 'media\\standard\\SaveFile'+str(obj.id)+'.z2s')) else: form =UploadModelForm() return render(request, "upload/upload.html", {"form": form})
