save as json or map to django model and then save?
So I have this data I want to save using postgreSQL and Django. The data will come from an external source in the format of json according to the following format: "$schema": "http://json-schema.org/draft-06/schema#", "type": "object", "properties": { "RESPONSE": { "type": "object", "properties": { "RESULT": { "type": "array", "items": { "properties": { "_attr_id": { "type": "string" }, "TrainStation": { "type": "array", "items": { "type": "object", "$ref": "#/definitions/TrainStation" } }, "INFO": { "type": "object", "properties": { "LASTMODIFIED": { "type": "object", "properties": { "_attr_datetime": { "type": "string", "format": "date-time" } }, "additionalProperties": false }, "LASTCHANGEID": { "type": "string" }, "EVALRESULT": { "type": "array", "items": {}, "additionalProperties": true }, My questions, what is the best way to save this data if I want to use later run operations on this. Is it to save it as jsonb or should I actually create a django model to map it and save it that way? -
HTML: Image not displaying
I have an .html file, main.html, in the following project folder /home/bugs/django_projects/mysite/home/templates/home/main.html In the same folder I have an image Bugs.jpg. Eg /home/bugs/django_projects/mysite/home/templates/home/Bugs.jpg I am trying to include the image in the webpage via: <img src="Bugs.jpg">, but the image does not display. I have tried debugging via: https://sebhastian.com/html-image-not-showing/, but I appear to be referencing the correct location of the file. The full code for main.html is below. <!DOCTYPE html> <html lang="en"> <head> <title>B.

Detecting AJAX call in a Django view function
I need Ajax functionality in my Django application. Therefore, a jQuery code calls a Django view function that returns data (here in a simplified form). $(document).ready(function() { // Prevent the form from being submitted normally $('#filter-form').on('submit', function (event) { event.preventDefault(); $.ajax({ url: '/filter_view/', type: 'POST', headers: { 'Accept': 'application/json', 'X-Requested-With': 'XMLHttpRequest', //Necessary to work with request.is_ajax() }, success: function (response) { console.log(response); } }); }); }); The problem is the verification - in the Django view -, that it received an Ajax call. Previously, this could be done by 'is_ajax()', but this function is deprecated. It was replaced, then, by if request.method == 'POST' and request.META.get('HTTP_X_REQUESTED_WITH') == 'XMLHttpRequest': or if accept_header == 'application/json' or x_requested_with_header == 'XMLHttpRequest': That all worked. All of a sudden, it did not work anymore, because, although the headers were declared in the AJAX code, headers: { 'Accept': 'application/json', 'X-Requested-With': 'XMLHttpRequest', //Necessary to work with request.is_ajax() } they do not arrive in the Django view. Nothing was changed in the Django middleware. The Chrome browser, used for debugging of the JQuery code, was reset. I dont have the slightest idea, why the headers settings do not get through. Any help would be appreciated. -
Django : Edit main.html to reference static webpage
I am learning Django and I am still very new to it so I don't yet understand how all the pieces fit together. I have successfully built the polls application on the tutorial website (https://docs.djangoproject.com/en/4.2/intro/tutorial01/) and a 'Hello World!' app as an additional test.

Is it possible to pass the newly created user instance from the registration page as context to the payment-process page? Any help would be greatly appreciated. Code below: VIEWS def register(request): if request.method == "POST": form = RegisterForm(request.POST) if form.is_valid(): form.save() return redirect("process-payment") else: # create empty form for user to fill in form = RegisterForm() return render(request, "register/register.html", {"form": form}) def payment_done(request): return redirect('login') def process_payment(request): host = request.get_host() paypal_dict = { "cmd": "_xclick-subscriptions", 'business': settings.PAYPAL_RECEIVER_EMAIL, "a3": "1.75", # monthly price "p3": "1", # duration of each unit (depends on unit) "t3": "M", # duration unit ("M for Month") "src": "1", # make payments recur "sra": "1", # reattempt payment on payment error "no_note": "1", # remove extra notes (optional) … -

How can I specify OneToMany relationship in Django models?
I am using Django for fetching data from the join of three tables. Table1, Table2, and Table3 all have a column name cols. I want to join all three tables and have to define the models for that. I can use models.ForeignKey but as per the documentation: The field on the related object that the relation is to. By default, Django uses the primary key of the related object. If you reference a different field, that field must have unique=True. But the field cols in Table3 is not unique, there can be duplicate values for the field. Then how can I do the OneToMany relationship for these tables? I could use ManyToMany but then it violates the relationship between Table1 and Table2 as they have unique values for the column. -
Amazon S3 Bucket static files not accessible from my Heroku-hosted Django app
Django app hosted on Heroku. All static files are in an AWS S3 bucket with "Block all public access: Off", ACL set to "allow list/read" across the board, and the "access: public" tag is displayed under permissions. Launching Django app from Heroku dashboard is met with Bad request 400 error. Launching with debug=True shows more: "SuspiciousOperation at / Attempted access to '/img/faviconB-32x32.png' denied." Removing the link tag for that exact resource in my index.html is no improvement, same error occurs for any remaining static files. I can access any item in the bucket with its object url without issue, for example: https://heroku-brainteasers-app-tmurphy.s3.us-east-2.amazonaws.com/static/img/brainteaserslogo.jpg my django settings.py: AWS_ACCESS_KEY_ID = os.environ.get('AWS_ACCESS_KEY_ID') AWS_SECRET_ACCESS_KEY = os.environ.get('AWS_SECRET_ACCESS_KEY') AWS_STORAGE_BUCKET_NAME = 'heroku-brainteasers-app-tmurphy' AWS_S3_CUSTOM_DOMAIN = f'{AWS_STORAGE_BUCKET_NAME}.s3.amazonaws.com' AWS_S3_SIGNATURE_VERSION = 's3v4' AWS_DEFAULT_ACL = None # Use S3 bucket's setting AWS_S3_OBJECT_PARAMETERS = { 'CacheControl': 'max-age=86400', } AWS_LOCATION = 'static' STATICFILES_STORAGE = 'mydjangosite.storage_backends.StaticStorage' DEFAULT_FILE_STORAGE = 'mydjangosite.storage_backends.PublicMediaStorage' STATIC_URL = f'https://{AWS_S3_CUSTOM_DOMAIN}/static/' MEDIA_URL = f"https://{AWS_S3_CUSTOM_DOMAIN}/media/" STATICFILES_DIRS = [ BASE_DIR / 'static', ] If I remove all the static file 's from my html, taking the bucket out of the loop entirely, the app loads and I see the home page. It seems like the django settings are failing to request the resources properly from my bucket, … -
Check if an id is in another model's field, and get the connected values
Given these two models: class Event(models.Model): title = models.CharField(max_length=200) class dateEvent(models.Model): venue = models.ForeignKey(Venue, on_delete=models.CASCADE,null=True, blank=True) event = models.ForeignKey('Event', on_delete=models.CASCADE) class Venue(models.Model): venue_name = models.CharField(max_length=50) How can I filter only the venues that appear in a dateEvent? And how can I get the Event details linked to a specific venue? Right now I attempted this, which returns noniterable and non exists error: venues = list(Venue.objects.filter(dateevent__venue.icontains=id).values('venue_name', 'dateevent__event.id') -

Django - "" appearing under <body> tag and adding space to page
I noticed this when i was getting spacing above the navbar, after Inspecting the page i found a random "" under tag which is causing to add a space on the page. This doesnt show up if i stick all the html in one file (home.html) and runserver. However, when i start using extends or includes with my base.html, "" pops up. Any ideas on possible fixes? I am using Visual Studio Community 2022 - Version 17.5.2 Inspect Page <!doctype html> <html lang="en"> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1"> <title>Test</title> </head> Byte Order Mark - it might have something to do with utf-8 with BOM? ive tried copy/pasting in notepad and saving as.. utf-8 without BOM and then pasting back into the html file but it didnt work I used: $(document).ready(function () { let html = document.querySelector("html"); let cleanHTML = html.innerHTML.replace(/[\u200B-\u200D\uFEFF]/gim, ''); html.innerHTML = cleanHTML; }) seems to be removing the problem but i would like to find the root cause of why this is happening instead of pasting code in every project
