Postman CLI collection run not using cookieJar correctly
I'm trying to use postman with a Django API and I'm writing some tests for the API. However I'm encountering an issue with postman when run through the console using postman collection run <collection_id>. I'm using Postman's cookieJar to set and get cookies between requests but I have two of them and it is only adding one when running using the command. This behaviour doesn't happen when run through postman itself. Here's the test script that runs the code for adding the cookies: console.log(pm.request) if (pm.request.url == "http://localhost:8000/api/auth/login/" && pm.request.method == "GET"){ const cookieJar = pm.cookies.jar() let temp = pm.response.headers; let temp2 = temp.filter(item => item["key"]=== "Set-Cookie") let temp3 = temp2[0].value let temp4 = temp3.slice(10,42) cookieJar.set("localhost", "csrftoken", temp4); console.log("Ran tests script") } if (pm.request.url == "http://localhost:8000/api/auth/login/" && pm.request.method == "POST"){ const cookieJar = pm.cookies.jar() pm.response.forEachParent(console.log(pm.response)) let temp5 = pm.response.headers; let temp6 = temp5.filter(item => item["key"]=== "Set-Cookie") let temp7 = temp6[0].value let temp8 = temp6[1].value let temp9 = temp7.slice(10,42) let temp10 = temp8.slice(10,42) console.log(temp9) console.log(temp10) cookieJar.set("CLI1", "csrftoken", temp9); cookieJar.set("CLI2", "sessionid", temp10); } The output for the console.logs near the bottom do show that there are values, even when run through the CLI but for some reason the second cookie isn't set … -

django migration with multiple languages
It seems makemigrations command is affected by django language (django.mo, django.po etc). I have two projects. One is upstream and the other origin is forked version of upstream. Upstream's LANGUAGE_CODE is ko-kr and that of origin is en. In upstream when I run makemigrations, provided that I have django.mo file under locale/ko/LC_MESSAGES no changed detected. Now I head to origin whose language is en. I have locale/en/LC_MESSAGES/django.mo file. When I run makemigrations I see a long list of migration files. But with a close look, all of them are about changes of verbose_name, choices label etc. When one has django project that supports more than one languages, how does one make it recognise its language and prevent it from making unnecessary migration files? -
'RecursionError: maximum recursion depth exceeded' when I try to run a server

Intermittent Character Encoding Issue with Django, Celery, and SendGrid
I've been working with a setup that uses Django alongside Celery for dispatching emails, and we've integrated SendGrid for this purpose. However, I've come across a peculiar issue that I hope someone might shed some light on. Sometimes, when sending out emails, characters with diacritics, specifically "ì", are being displayed as another character, in this case, "ě". I've double-checked and ensured that all software configurations are set to utf-8 encoding, but this inconsistency persists. Has anyone encountered a similar issue or have any suggestions on how to debug or fix this? Example: "Martedě" instead of "Martedì" Martedě" instead of "Martedì The templates are saved in utf-8 encoding html files. This is the code used to send emails: message = render_to_string( "emails/booking_canceled/cliente_to_client.html", { "first_name": booking.customer_first_name, # ... }, ) email = EmailMessage( subject=subject, body=message, from_email=DEFAULT_FROM_EMAIL, to=[booking.customer_email], headers={"Content-Type": "text/html; charset=UTF-8"}, ) email.content_subtype = "html" email.send() logger.info( "[booking_code: %s][customer_email: %s] Sent.", booking.code, booking.customer_email, ) Thank you in advance for any assistance! -

build API for support pagination and non-paginate on django rest framework
As I work on Django-rest-framework. I want the API to support dynamic pagination. For example, if user need pagination they can use an endpoint /api_url?offset=0&limit=10(should return with the format that can let the user know the current page and have the next page or not) and if they don't want pagination they just request without params /api_url. I need it to work with django_filters so it won't make many requests to SQL. I expect to get solition or sample code to about this problem. -

pylint_django "Instance of 'ForeignKey' has no ... member"
I'm working on a project in python with django and recently I decided to modify the way the models were stored in one of the apps. With the help of django documentation, I deleted the models.py file and created a models folder in which I put all my models in files and created a _init_.py file in which I import all my models. This solution works but now pylint no longer seems to understand ForeignKeys. this is my app tree: apps myapp models _init_.py mymodel.py mymodel2.py if i run pylint i can see some E1101. let's take an example: i have a model subnet in subnet.py: class Subnet(models.Model): def __str__(self): return self.nom + "(" + self.cidr + ")" net = models.ForeignKey("Network", on_delete=models.CASCADE, related_name="subnets") def get_parent_cidr(self): return self.net.cidr this model have a reference to the network models in network.py: class Network(models.Model): def __str__(self): return self.company.name + " - " + self.nom + " - " + str(self.cidr) cidr = models.CharField(max_length=18) this network object have a cidr field, all seems to be fine but when i run pylint with the pylint_django plugin, this one send me an error: project/apps/myapp/models/subnet.py:74:15: E1101: Instance of 'ForeignKey' has no 'cidr' member (no-member) What did I do … -

join some table twice in Django ORM
I have two models class Customer(AbstractBaseModel): uuid = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False, db_column='uuid') name = models.CharField(max_length=55) class CustomerAddress(AbstractBaseModel): uuid = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False, db_column='uuid') customer = models.ForeignKey(Customer, on_delete=models.DO_NOTHING, related_name='addresses', db_column='customer_uuid') country_code = models.CharField(max_length=3) type = models.CharField(max_length=8, choices=[('shipping', 'shipping'), ('billing', 'billing')]) User can filter customers using two fields: billing_country and shipping_country, they can fill either one or both fields. If user fills both fields, I have to join to CustomerAddress table twice. I do this in raw SQL like this: SELECT * FROM customer c LEFT OUTER JOIN address shipping_address ON shipping_address.customer_uuid = c.uuid AND shipping_address.type = 'shipping' LEFT OUTER JOIN address billing_address ON billing_address.customer_uuid = c.uuid AND billing_address.type = 'billing' and append WHERE clauses if user uses filters like this: # billing_country and shipping_country are sanitized at this point filters = [] if billing_country: filters.append(f"billing_country_code = '{billing_country}'") if shipping_country: filters.append(f"shipping_country_code = '{shipping_country}'") where_part = 'WHERE ' + ' AND '.join(filters) How can I do this using Django ORM? -
Best practices for masking sensitive data on django
In a django project, I am sending requests to third party services and keeping a log of these requests, but I want to censor some sensitive data (password, token, etc.) when saving to the database. I wrote a Handler, which works correctly, but I could not do the masking part. I tried with logging.Filter, but it was not the right approach. When I wanted to try logging.Formatter, I could not save to the database because the returned record was a string, not an object. What is the best way to mask this kind of data? Is it to write a masking function in the handler or some other method? I cannot use third party package because it is a company project -

Avoid code duplication between django Q expression and as python code

These two forms have become a bit of a maintainability issue as PM keeps on changing the definition of can_delete. -

Is it possible to use template tags inside model field for displaying static images?
I have a huge report with some 50+ pages and there are several images and tables inside them.

So what's the best way to display them because in templates I call chapters like report.chapter_one and it displays a wall of text where I can't put image from inside template
