Django foreign key as primary key?
The question In Django, is it possible to use a foreign key as the primary key for a model? For example: Context Let's say that we have class Reporter that has many Articles, but if we remove our reporter from our database, we also want the articles that belonged to them to be deleted. The schema is a one-to-many relationship, where one reporter has many articles, and the existence of the article instances in the database relies on the reporter instance. What I am confused about specifically What kind of Django relationship would I need to achieve this business requirement? Unfortunately, I have read all of the Django documentation. Therefore, I cannot find which database relationship makes the most sense, and I hope someone with more experience than me in Django and PostgreSQL can help out. Bonus points Imagine that each article needs to be in a specific arbitrary order and that this is also a constraint of the database relationship. -
AWS S3 Lambda Trigger Not Working When Uploaded to Bucket Subfolder
I have a Lambda Python function that will resize images on upload. Everything is working correctly, but only when I upload directly to the bucket. When I upload files to the bucket/uploads/ folder, it would no longer trigger the resize function. I have tried the filtering options in the trigger settings uploads/ to no avail. Assuming it is related to my Lamda function and the folder should/must also be included? Here is my Lambda function: def lambda_handler(event, context): for record in event["Records"]: bucket = record["s3"]["bucket"]["name"] key = record["s3"]["object"]["key"] download_path = "/tmp/{}{}".format(uuid.uuid4(), key) upload_path = "/tmp/resized-{}".format(key) s3_client.download_file(bucket, key, download_path) -

Django context processor not rendering from shell
Using Django 3.2 Have defined few global variables like app/context_processors.py from app.settings import constants def global_settings(request): return { 'APP_NAME': constants.APP_NAME, 'APP_VERSION': constants.APP_VERSION, 'STATIC_URL_HOST': constants.STATIC_URL_HOST } and in settings.py file TEMPLATES = [ { ...

Why my generated docx in javascript from a blob is filled with [Object Object]?
I'm sending data to my Django backend through a POST request, the server then creates a docx using this data and sends it back to me where I'm trying to download it using the following code : axios.post(route, data).then((res) => { const filename = "report.docx" var blob = new Blob([res], { type: 'application/vnd.openxmlformats-officedocument.wordprocessingml.document' }); var link = document.createElement('a'); var URL = window.URL || window.webkitURL; var downloadUrl = URL.createObjectURL(blob); link.href = downloadUrl; link.style = "display: none"; link.download = filename; document.body.appendChild(link) link.click() link.remove() }); The download of the file works but when I open it, it only contains [Object Object], what am I doing wrong here ? I checked the backend and the document is properly created as it has the right content when I'm saving it when it's generated in the server so it's either that i'm sending it badly or creating the file in the frontend badly. Here is how I send it from the backend : #Generating the doc properly before this... response = HttpResponse(content_type='application/vnd.openxmlformats-officedocument.wordprocessingml.document') report_filename = 'graph-report-'+now.strftime('%Y-%m-%d_%H-%M-%S')+'.docx' response['Content-Disposition'] = 'attachment; filename=%s'%(report_filename) document.save(response) return response Thanks for helping me. -

django orm filters and nested Prefetch

Rendering Grafana inside django website using API Key
I’m attempting to pass an API token for a user to grafana from our own internal website so that the main gui renders in an iframe. We don’t want the users to have to log into grafana after they have logged into our site, so we are creating their users in grafana, building an API token and attaching that to the user for our website. When the user goes to the page that has the grafana iframe, we are sending an ajax get request with the token so grafana renders the main dashboards with the users information. If we do just a standard iframe everything works fine and we render inside the frame. We can get to the login page and do everything we need to. When I add the token so we don’t need to authenticate nothing renders and I see no errors/logs on either grafana or the website. If I send an invalid token I see the expected “401 invalid Api key” error on both the website and the grafana logs. This is what I’m sending from the website… <div class="content"> <div class="container-fluid" id="container"> </div> </div> <script> $.ajax({ url: "{{url}}", type: "GET", beforeSend: function(xhr){ xhr.setRequestHeader('Accept', 'application/json'); xhr.setRequestHeader('Authorization', 'Bearer … -

How to call Django model method from admin
I have a model that is seperate to a user model which stores passwords, I have implemented a set_password method on that model, and this works ok, the only place I am facing issues is the admin panel, if I try to update a password in the model from the admin it does not call this set_password method. Instead it inputs the password as plain text. Is there a way to override the admin panel so it calls the set_password method? class MyModel(models.Model): name = models.CharField(max_length=255) created_on = models.DateTimeField(default=timezone.now) encrypted_pass = models.CharField(max_length=255, null=False) def set_password(self, raw_password): self.encrypted_pass = make_password(raw_password) -

Article.objects.order_by('order') vs type(self).objects.order_by('order')

And it works the same way! But which is better? What is more correct? And what's the difference in that? -

Django reset password url in email only works if copy and paste it, not click on it
When I request a password reset with the built in django machinery, it will generate a URL in the email like this: https://example/accounts/reset/MTA/atspc3-7c45df8a600243fde3dfb60c44873f15/ In gmail if I go show URL, the text is indentical since it is being generated as a plain/text email. If I click the link in gmail, or outlook then it goes to (maybe after a redirect, I can't tell since its so fast): https://example.com/accounts/reset/MTA/set-password/ And it says Password reset unsuccessful The password reset link was invalid, possibly because it has already been used. Please request a new password reset. However if I copy and paste the URL into the browser, then it works. However no-one copies and paste the URL, they all click the link and say it does not work. I don't get why clicking on the link does not work since it is correct? How does one even debug this? -
