Django MRO for permission subclasses
I am using Django 3.2 I have a model Foo, and I want users to be able to update/delete objects that they created. To that end, I have written a OwnerPermissionMixin class as follows: /path/to/permissions.py class OwnerPermissionMixin(PermissionRequiredMixin): owner_attribute = 'owner' def has_permission(self) -> bool: """ Require the the user has the relevant global permission and is the owner of this object. :return: Does the user have permission to perform this action? """ return self.request.user.is_superuser or ( super().has_permission() and self.request.user == getattr(self.get_object(), self.owner_attribute) ) /path/to/views.py class FooUpdateView(LoginRequiredMixin, OwnerPermissionMixin, UpdateView): model=Foo class FooDeleteView(LoginRequiredMixin, OwnerPermissionMixin, DeleteView): model=Foo My question is: am I inheriting the base classes in the right order? both Mixins have the same base class AccessMixin - and it seems to make sense (from a philosophical point of view), that LoginPermissions are enforced before Owner permission - but I want to make sure I'm not missing anything obvious. -
Taggit Django - Return View of Posts Based on User Post Tags)
I have recently been playing around Taggit. I have managed to filter my Posts model, based on different Tags by adding the following filter .filter(tags__name__in='categoryone'). Although, would anyone be able to provide me with guidance on how to filter my Posts based on the tags my user has already used within his or her previous posts? So for example, if my user has previously created a Post within the "categoryone" tag, all the posts he or she would see on their Post Feed would be tags relevant to "categoryone" but he or she wouldn't see any posts within "categorytwo" or "categorythree" unless he or she makes a post within either or both of those categories. I was hoping something such as .filter(tags=self.request.user) but this is throwing an Instance error. Any examples would be greatly appreciated! :-) Thanks! -
Django sending Html email template with javascript functions
I am trying to send an HTML Template over email in DJANGO site and for some reason javascript part isn't working . Email is sent sucessfully with an image only a function is not working in email browser. Here's the template code. <html> <script> function validate() { var x = document.forms["form"]["eid"].value; if (x == "E101") { document.getElementById('id1').style.display='block'; return false; } } </script> <body> <h2 style="color:red;">Hello </h2>,<br> <p >Please find the OTP for requested file.<p><span style="width" class="">File Name :{0} </span></p> <p ><span style="width" class="">OTP : {1} </span></p> <div id="id1" style="display:none;"><img src="cid:0" ></div> <form name="form" onsubmit="return validate()" method="post" required> Employee id: <input type="text" name="eid"> <input type="submit" value="Submit"> </form> <p> </body> </html> -
custom result per logged in user in Foreign Key dropdown django admin
I have a model Called Business and it has many BusinessAddress inside. When userA creates Business say - business_a and then when he creates the BusinessAddress business_address_a_1 He could be able to choose the business_a in the dropdown. But when userB creates his business_b and then when creating the BusinessAddress, dropdown form for foreign key Business in Django admin should not show business_a and business_b instead it should only show business_b and if more business created by the userB that too. My model sample is like this class Business(models.Model): title = models.CharField(max_length=200) def __str__(self): # Show title as the identifier return self.title class BusinessAddress(models.Model): business = models.ForeignKey(Business, on_delete=models.DO_NOTHING) address = models.CharField(max_length=200) def __str__(self): return self.business.title I earlier added the changes to only show the business and business address of the particular user using overriding the get_queryset . But Since Django is new to me I couldn't find a way to achieve this. Could someone guide me on this? -
Best Way to Override Bootstrap Colour Variables
I have a Django (Wagtail CMS) project and I am trying to create a functionality that will allow me to change the 8 Bootstrap theme colours, more about that here. In order to override those colours, I need to use Bootstrap via the SCSS source. I'm using django-compressor to compress the static files in HTML and django-libsass as a SASS compiler. This is in my settings file (settings/base.py) COMPRESS_OFFLINE = True LIBSASS_OUTPUT_STYLE = 'compressed' LIBSASS_SOURCEMAPS = True LIBSASS_PRECISION = 6 This is my HTML file (templates/base.html) {% compress css %} <link rel="stylesheet" type="text/css" href="{% static 'css/style.css' %}"> <style type="text/x-scss" media="screen"> $dark: #000000; </style> <link rel="stylesheet" type="text/x-scss" href="{% static 'scss/bootstrap/bootstrap.scss' %}"> {% endcompress %} I am trying to override the "dark" theme colour with #000, this hex will be replaced with a template tag. The above code doesn't seem to work. But, the code below works: {% compress css %} <link rel="stylesheet" type="text/css" href="{% static 'css/style.css' %}"> <style type="text/x-scss" media="screen"> $dark: #000000; @import "engine/static/scss/bootstrap/bootstrap.scss" </style> {% endcompress %} Now the second code snippet of my base.html file works perfectly, but having an @import seems to be very inefficient. I could create a custom SCSS file with my own colour overrides, but … -

I want to insert environmental variables from an .env file into my containerized Django application, so I can use it to securely set Django's settings.py.

social_auth_app_django pipeline: first time visitor issue
I'm trying to implement social auth with google-oauth2. I almost implemented it, but I'm confused about first-time social visitor scenario: Suppose the social user visited my site for the first time and attempted to authenticate with using Google. In this case he won't be logged in, but only registered on my website. In order to log in this user has to click on authentication with Google button the second time, and when he already registered on my system the logging in will be successful. Questions: Is it a standard routine for the first time visitors? Is it possible to log the social user on the first attempt? I'm using the following social auth pipeline: SOCIAL_AUTH_PIPELINE = ( # Get the information we can about the user and return it in a simple # format to create the user instance later. In some cases the details are # already part of the auth response from the provider, but sometimes this # could hit a provider API.

Django - Query values based on the result of an existing query
I have a query that matches some foreign key properties buy_book__entity and sell_book__entity to a parameter company_group. I need to further add onto this query to filter the results only on the results that match a predicate. Is this possible to do in one query? return (Q(buy_book__entity__company_groups__alias__iexact=company_group) & \ Q(sell_book__entity__company_groups__alias__iexact=company_group)) & \ # I only want to run the below query on objects which # the book entity types are internal (Q(buy_book__entity__primary_company_group__alias__iexact=Case( When(buy_book__entity__type=ENTITY.INTERNAL, then=Value(company_group)), default=Value(None))) | \ Q(sell_book__entity__primary_company_group__alias__iexact=Case( When(sell_book__entity__type=ENTITY.INTERNAL, then=Value(company_group)), default=Value(None)))) I tried the above query utilizing Case and When but this doesn't exactly work because it will give the value as None to the primary_company_group whereas I need it not to query by that at all, almost like an ignore. Since primary_company_group is a nullable foreign key this skews my results heavily. Just FYI, I don't want to filter all entity__type to internal. Just the ones that are internal, I need to run the further query on those. -

Is there any added advantage of using djangorestframework over JsonResponse?
I am new to Django and API creation. I am trying to figure out if it is better to use djangorestframework or just use JsonResponse. I got the suggestion of djangorestframework from Digital Ocean's tutorial but also found out about JsonResponse, which seems simpler given that I don't have to install another package. Goal: I would like to be able to provide user information for both web and mobile applications. I see that there are some reasons provided on this post for djangorestframework, which I pasted below for posteriority. The common cases for using DRF are: 1)You're creating a public-facing external API for third-party developers to access the data in your site, and you want to output JSON they can use in their apps rather than HTML. 2)You're doing mobile development and you want your mobile app to make GET/PUT/POST requests to a Django backend, and then have your backend output data (usually as JSON) to the mobile app. Since you don't want to pass back HTML to the mobile app, you use DRF to effectively create a REST API that your mobile app can call. 3)You're creating a web app, but you don't want to use the Django templating … -

Django project on Heroku processing long requests. Background Jobs and Queueing
I have a Django project on Heroku, The project has an endpoint that accepts the client's request and sends it to other external services, the approximate response of which is from five seconds to two minutes. As known, if the process takes longer than 30 seconds, the platform will return an error h12 request timeout (and in general, the answer to the request must be given as soon as possible). I studied Background Jobs and Queueing and realized that I would need such instruments as RQ and Celery. In general terms, I understand the concept of each individual topic, but I do not really understand how to apply this to the project and whether I correctly assembled a bunch of tools for my task. Also, I don't understand how I can save the response of external services and I will need to inform the initiator of the request to my server (client request) about the result. I would be grateful for any hints, suggestive answers, and helpful resources. Thank you -

Creating custom Django encrypted field with Fernet
I'm trying to create a django custom encryption field using Fernet. The libraries I found for doing it automatically seems to be outdated/non compatible with Django>3.0 In this thread I found the following code: import base64 from django.db.models import CharField from cryptography.fernet import Fernet from cryptography.hazmat.backends import default_backend from cryptography.hazmat.primitives import hashes from cryptography.hazmat.primitives.kdf.pbkdf2 import PBKDF2HMAC from core import settings class SecureString(CharField): salt = bytes(settings.SECURE_STRING_SALT, encoding="raw_unicode_escape") kdf = PBKDF2HMAC(algorithm=hashes.SHA256(), length=32, salt=salt, iterations=100000, backend=default_backend()) key = base64.urlsafe_b64encode(kdf.derive(settings.SECRET_KEY.encode('utf-8'))) f = Fernet(key) def from_db_value(self, value, expression, connection): return str(self.f.decrypt(value), encoding="raw_unicode_escape") def get_prep_value(self, value): return self.f.encrypt(bytes(value, encoding="raw_unicode_escape")) It seems to work for the encoding part (if I check the database field with a manager program, content is show as a sort of chinese characters), but not for decoding. Everytime I save a record in Admin, this error is triggered (although saved in database): raise TypeError("{} must be bytes".format(name)) TypeError: token must be bytes Aren't supposed to be already as bytes in the database record, due to get_prep_value code? The same error happens when trying to list records in admin (accessing the reading function). How can I solve this? I am using SQL Server as database (in case it might be relevant). -
Access-control-allow-origin header not recognised in browser
We've aded some javascript code to a web-page which needs to POST information to our Django-backend for analysis. In the head of the site, we've added a line like this: <script src="https://somedomain.com/track/" type="text/javascript"></script> In turn it will fetch the complete code and do what it needs to. However, I'm running into an issue with Access-Control-Allow-Origin. I've added a custom middleware to the Django-project that looks like: class CorsMiddleware(object): def __init__(self, get_response): self.get_response = get_response def __call__(self, request): # Code to be executed for each request before # the view (and later middleware) are called. response = self.get_response(request) response["Access-Control-Allow-Origin"] = "*" return response I can try out the url and its headers via requests: import requests resp = request.get resp = requests.get('https://somedomain.com/track/') print(resp.headers['Access-Control-Allow-Origin']). # Prints "*" Those work - yay. But when I'm trying this out on the actual website, I keep getting the error [Error] Failed to load resource: Origin https://www.websitedomain.com is not allowed by Access-Control-Allow-Origin. What am I missing?
