Django PythonAnywhere (2003, "Can't connect to MySQL server (timed out)")
I'm trying to setup a Django project and I can't seem to connect to MySQL database made in PythonAnywhere. DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'username$dbname', 'USER': 'username', 'PASSWORD': 'password', 'HOST': 'username.mysql.pythonanywhere-services.com', } } I cant enter the database in the PythonAnywhere Bash with my user, host, name and password, but when i try to do it in django it appears as follows: django.db.utils.OperationalError: (2003, "Can't connect to MySQL server on 'username.mysql.pythonanywhere-services.com' (timed out)") -
how to manage MySQL and MongoDB at the same time with django
I have an affiliate site where the data for products is arbitrary such as length of clothes and using MySQL will not be flexible and a good option there. I want something dynamic such as MongoDB. I know about "djongo" but it converts every query to Mongo. I found this How to Hybrid Mysql and MongoDB in Django and it gave me hope that I may be able to use mongo for the products and keep the rest such as Auth, User management etc in MySQL. If you know anything then please let me know. Is it even possible? Can I use PyMongo to access mongoDB database and query data easily between both databases such as using relations(i.e Foreginkey, OneToOne etc) The reason I provided none of my code is that I only want to know the concept. -
Is the implementation of my add to cart / remove from cart secure?
I am building an ecom website and in order to implement an add_to_cart function I've done the following. Clicking the add to cart button calls the javascript add_to_cart function that I wrote: <button type="button" onclick = "add_to_cart({{ product.pk }})">Add to Cart</button> This is the function: function add_to_cart(product_pk) { let url = '/add-to-cart/' + product_pk.toString() $.ajax({ type: 'GET', url: url, processData: false, contentType: false }) } the urls for this look like this: path('add-to-cart/<str:product_pk>', views.add_to_cart, name='add_to_cart') and finally my view looks like this: def add_to_cart(request, product_pk): cart = request.session['cart'] cart.append(product_pk) request.session['cart'] = cart context = {'length_of_cart': len(cart)} return HttpResponse(content = dumps(context), content_type='application/json') tldr: Click button, button calls js, js makes get request to url, url triggers view, logic in view adds product to cart. I feel like this is pretty "hacky". Are there any security issues involved with what I've done here? -
Modifiying django defaultrouter URL
So I want the URL /users/ to retrieve not a list of users but only the current user username. What I did for achieving this is adding the list method and overwriting it, like this: def list(self, request, *args, **kwargs): """ Override list method so it only returns current user username. """ data = {"username": request.user.username} return Response(data, status=status.HTTP_200_OK) But I feel like it's not the correct solution because list it's supposed to retrieve all the users. There is a way in which I could change the Django default router behaviour? So the URL /users/ executes a different method, not list(). urls.py from django.urls import include, path from rest_framework.routers import DefaultRouter from users.views import UserViewSet router = DefaultRouter() router.register(r'users', UserViewSet, basename='users') urlpatterns = [ path('', include(router.urls)) ] Or maybe doing this is just fine and I should let it be how it is right now. -
Google Cloud Storage doesn't upload to the correct media and static directory in the bucket

How to pull data from database in Quill format and feed to a Quill form using Django-quill-editor
I have a Quill form that works to submit the Quill data to the database. Now when I call the form, I want to take data already in that form and display it in the Quill form to the user.

Django allauth OSError: [Errno 99] Address not available
I'm trying to implement django-allauth and faced this problem. For this project I'm using Docker as well. When I click "Sign up using VK" it redirects me to http://127.0.0.1:8000/accounts/vk/login/callback/?code=...random code... with this error. After going to sign up page again and clicking the same button it successfully redirects me to profile page which means the user was created. I couldn't find any solutions using Google so hope you can help. I don't think that was because of bad configuration because I've tested similar configuration on empty django project which was not containerized and everything worked properly. Maybe it's because inside docker container there's venv installed.

How to use multiprocessing in Python with Django to create thousands of model instances from xml file?
I have a script that parses data from an xml file into Django models. It works ok but recently we've been encountering files with dozen of thousands of models to create which is incredibly slowing down the process (up to 40 min to upload a single 20MB file). I would like to try and use multiprocessing to speed it up as much as I can but I am new to this package. This is the current setup: create_profiles_from_xml: is a function that loops through the data extracted from the xml, called xml_members, popping one element at a time (it has to be like that due to a relationship that can be created with the next element or not). create_profile: is a just a function that handles the data to match with the model fields and then call the .create() method, that's why I omitted the details of this function here. def create_profiles_from_xml(xml_members, device): profiles = [] while len(xml_members) > 0: parent_member = members.pop(0) profile = create_profile(parent_member, parent=None) if profile: profiles.append(profile) return profiles And here is what I tried to do with the multipocessing from multiprocessing import Pool def create_profiles_from_xml(xml_members, device): profiles = [] pool = Pool(processes=cpu_count()) profiles = pool.imap_unordered(create_profile, xml_members) … -

Set unique primary key based on foreignkey
I have a model defined as - class sales_order(models.Model): customer=models.ForeignKey() item=models.ForeignKey() branch=models.ForeignKey() --- ---other fields Now for each branch, I want to start the primary key from 1 ("id" for eg.), but the default functionality of Django will increment the id irrespective of any other data. I'm ok even if id keeps on incrementing as it does, and then I set my own field making it unique per branch and this field should auto increment without the user passing the data by checking the previous value from the database such as - class order_serializer(serializers.ModelSerializer): class Meta: validators = [ UniqueTogetherValidator( queryset=sales_order.objects.all(), fields=['myOwnDefinedField', 'branch'] ) ] I'm in a state of no idea how to achieve this.

Django : passing parameter or context with the function redirect and id encoded by hashids
I am a newbie and I need your help ! But maybe it's a complicated question even for experts, who knows! The following code works perfectly to generate a table (using a datepicker form to select the table's day) from the homepage, and with the ID page encoded with hashids in the URL, it redirects to the table URL generated for the day selected. For example, when a specific table is created for a particular day selected by the user, the page is redirected to http://127.0.0.1:8000/O3GWpmbk5ezJn4KR where "O3GWpmbk5ezJn4KR" is one table id encoded with hashids, this works fine. However, I would like to pass a variable with redirect(), the day selected in the datepicker used to create the table, in order to display the date on the html page rendered with the table generated. I tried the reverse function to pass the day variable with redirect, but if failed due to the hashid encoded URL not being recognized by the reverse function (example of error message obtained in the Shell : django.urls.exceptions.NoReverseMatch: Reverse for '/VvJ4openRe7Az1XP' not found. '/VvJ4openRe7Az1XP' is not a valid view function or pattern name.) Have you any idea to help ? Would appreciate any hint ! Best … -

Any idea what could be causing the error? {Traceback (most recent call last): File "C:\Users\User\dev\ergorite\src\services\backend\venv\lib\site-packages\django\core\handlers\exception.py", line 47, in inner response = get_response(request) File "C:\Users\User\dev\ergorite\src\services\backend\venv\lib\site-packages\django\core\handlers\base.py", line 181, in _get_response response = wrapped_callback(request, *callback_args, **callback_kwargs) File "C:\Users\User\dev\ergorite\src\services\backend\venv\lib\site-packages\django\views\decorators\csrf.py", line 54, in wrapped_view return view_func(*args, **kwargs) File "C:\Users\User\dev\ergorite\src\services\backend\venv\lib\site-packages\rest_framework\viewsets.py", line 125, in view return self.dispatch(request, *args, **kwargs) File "C:\Users\User\dev\ergorite\src\services\backend\venv\lib\site-packages\rest_framework\views.py", line 509, in dispatch response = self.handle_exception(exc) File "C:\Users\User\dev\ergorite\src\services\backend\venv\lib\site-packages\rest_framework\views.py", line 469, in handle_exception self.raise_uncaught_exception(exc) File "C:\Users\User\dev\ergorite\src\services\backend\venv\lib\site-packages\rest_framework\views.py", line 480, in raise_uncaught_exception raise exc File "C:\Users\User\dev\ergorite\src\services\backend\venv\lib\site-packages\rest_framework\views.py", line 497, in dispatch self.initial(request, *args, **kwargs) File "C:\Users\User\dev\ergorite\src\services\backend\venv\lib\site-packages\rest_framework\views.py", line 414, in initial self.perform_authentication(request) File "C:\Users\User\dev\ergorite\src\services\backend\venv\lib\site-packages\rest_framework\views.py", line 324, in perform_authentication request.user File "C:\Users\User\dev\ergorite\src\services\backend\venv\lib\site-packages\rest_framework\request.py", line 227, in user self._authenticate() File "C:\Users\User\dev\ergorite\src\services\backend\venv\lib\site-packages\rest_framework\request.py", line 380, in _authenticate user_auth_tuple = authenticator.authenticate(self) File "C:\Users\User\dev\ergorite\src\services\backend\venv\lib\site-packages\rest_framework_simplejwt\authentication.py", line 40, in authenticate validated_token = self.get_validated_token(raw_token) File "C:\Users\User\dev\ergorite\src\services\backend\venv\lib\site-packages\rest_framework_simplejwt\authentication.py", line 94, in get_validated_token return AuthToken(raw_token) File "C:\Users\User\dev\ergorite\src\services\backend\venv\lib\site-packages\rest_framework_simplejwt\tokens.py", line 43, in init self.payload = token_backend.decode(token, verify=verify) File "C:\Users\User\dev\ergorite\src\services\backend\venv\lib\site-packages\rest_framework_simplejwt\backends.py", line 90, in decode return jwt.decode( TypeError: decode() got an … -
Creating months based on start date and end date value in django
I have been working on an application where user is required to create monthly tasks, so I made a model named AcademicYear and Months, now I want to take only the start_month and end_month input from user, and based upon the values of these fields, I want to create months automatically once the year object is create. class AcademicYear(SingleActiveModel, models.Model): title = models.CharField(max_length=10) start_month = models.DateField() end_month = models.DateField() def __str__(self): return str(self.title) class Months(models.Model): year = models.ForeignKey(AcademicYear, on_delete = models.PROTECT, related_name='year') months = models.CharField(max_length = 20) ??? what could be the logic or a solution which can be applied here?
