Django connection with Sybase SQL Anywhere 17 with pyodbc on Digital Ocean App Platform
I need help with connecting to the Sybase SQL Anywhere database via the pyodbc library. When I am running a local development server or local python desktop script connection is established easily and successfully. I found out that the problem is in the SQL Anywhere 17 driver. In the scripts below you can see that when I run pyodbc.drivers() in a local environment I get a list with a few drivers, and when I repeat the same in the App platform application console I get an empty list. My question is how can I install or transfer SQL Anywhere 17 driver to the App platform or ubuntu droplet? Thank you! views.py code connection_string = "Driver=SQL Anywhere 17;" \ "Server=xxx;" \ "Host=host;" \ "UID=user;" \ "PWD=pass;" \ "DBN=db_test;" \ "Port=xxxx;" \ "DSN=xxxx;" \ "dobroadcast=all;" \ "APPINFO=xxx;" def my_view(request): rows = [] with pyodbc.connect(connection_string) as conn: cur = conn.cursor() cur.execute('SELECT NAZIV1 FROM ARTIKEL') rows = list(cur.fetchall()) return render(request, 'app/my_template.html', {'rows': rows}) -

How to get() the non-numeric primary key field's value during model save
I am trying to catch the primary key field's value during model save using: def save(self, *args, **kwargs): if self.pk: # For some post processing, I am trying to catch the instance "ID", and make changes to fields cls = self.__class__ old = cls.objects.get(pk=self.pk) # Getting current model state. << Error occurs here new = self # Newly instantiated model object with new values. # ... # ... This works fine if I have the following model definition (primary key as Integer): class myModel(models.Model): some_fld_id = models.AutoField(primary_key=True, verbose_name='... However, if I use a charField as the primary key like so: class myModel(models.Model): some_fld_id = models.CharField(primary_key=True, max_length=6, ... It fails with error: myModel matching query does not exist. And points to the line with: old = cls.objects.get(pk=self.pk) Now due to some constraints, I am to define the primary_key as a charField (and still be able to catch the pk value). How can I achieve this. -

Extra fields on many-to-many relationships: How to automatically create the "through" fields?
I'm trying to use a many to many field in order to add a set of facilities to a lead. The trouble is that i need an extra field for the date and time of the tour scheduled for each of the facilities i add to the lead. So when i create a lead and add facilities to the lead i have that extra field where i can enter date and time and access it afterwards as a list of facilities with their tour dates on the leads page. I came across many to many fields using "through" but I'm not sure if that's even the right option to use in this case. ManyToMany Fields with extra fields How can i use a many to many field using "through" and have the through field automatically be generated for each facility i add to my lead with the many to many field?

In Django with all-auth, how do I pass the authenticated user from the front end to be saved in the database table through a form?
I have been able to get my form to write to the database but I have two issues. One with passing the site_name to the slug field so that the user doesn't have to manually enter a slug and one passing the authenticated user to the "pilot" field automatically. I'd like to address the user issue with this question. When I render all fields of the model as a form I am able to manually select the user from a drop-down list of the possible users (all users) when submitting a form. I would like to take this field away from the form and have it auto-populate with the name of the currently authenticated user. Is there a way to set the default value in 'pilot' field of the model to be the currently authenticated user? I have tried a few different ways but I am running into different errors. I am very new to Django so don't have a great understanding. I have included the previous attempt in the view commented out. Thanks for your help.

Directional/ guidance related to Django, secured code hosting
I just joined today and this is my first post. I hope everyone is doing well. First, NOT AT ALL am a programmer and therefore there may be some elementary dependency in my posts (note this first). For some reasons, I was tasked to start a web application (small with, but have the potential to be scaled in the future with a proper dev team)... My questions below are very conceptual, I would need your thoughts/expert advice here. NOTE: The application is an analytics tool that is 80% forms, tables, tree charts, dropdowns and popups that interact with the database to extract the data on the front end and manipulate the data in the database based on user input. To develop the application in less time, we use the Django framework. In the YouTube tutorials, I see that the web UI is open on localhost:8000. How can I redirect this address so that it appears in my URL? How secure are the shared domains offered by web hosting companies (like GoDaddy, Hostinger, etc.)? When the time is right, all applications need to be hosted in the cloud, with proper security encryption of the data. Is there a good data management … -

I use POST methon in Django, but my request.method == 'POST' said that it's GET methon
I don't know why my create function worked before, but now is not working. I see only "It's not POST, it's GET". I have tried to delete something, for example: from def index(request): email = str(request.GET.get('autorization_email')) and from def create(request) type_values = Type.objects.all() model_values = Model.objects.all() equipment_values = Equipment.objects.all() It didn't helped url.py urlpatterns = [ path('', views.autorization, name='autorization'), path('home/', views.index, name='home'), path('return_equpment/', views.return_equpment, name='return_equpment'), path('create/', views.create, name='create'), ] create.html {% block content %} <form method="post" action="{% url 'create' %}"> {% csrf_token %} ... <button type="submit" class="btn btn-success">Save</button><br> <span>{{ error }}</span><br> </form> {% endblock%} views.py from django.shortcuts import render, redirect from .models import Booking, Type, Model, Equipment from .forms import BookingForm error = '' email = '' def index(request): global email global error email = str(request.GET.get('autorization_email')) context = { 'title': 'Main page', 'error': error, 'index_email': email } return render(request, 'main/index.html', context) def create(request): type_values = Type.objects.all() model_values = Model.objects.all() equipment_values = Equipment.objects.all() form2 = BookingForm() global error global email context = { 'form': form2, 'error': error, 'type_values': type_values, 'model_values': model_values, 'equipment_values': equipment_values, 'create_email': email } if request.method == 'POST': form2 = BookingForm(request.POST) form2.email = email form2.type = request.POST.get('type') form2.model = request.POST.get('model') form2.number = request.POST.get('number') if form2.is_valid(): form2.save() return redirect('autorization') else: … -

How to handle migrations for 3rd-party django apps in a deployment pipelines?
I'm using a 3rd party dependency modeltranslation-lokalise which requires me to run python manage.py makemigration. This will generate a migration file that sits within the package directory once generated, and therefore are not source controlled. For all other migration files I'm keeping them in source control and would like to do the same for these, as it will allow us to track changes to the database in the environments we use, ensuring they can be easily replicated and that operations are not duplicated on the same database (e.g. by having the same operation exist in differently-named migrations). My question: How are these 3rd party migrations meant to be handled when building and deploying to production (e.g. via a Dockerfile in a build pipeline? My guess would be to find a way to reliably extract the migration files from the package and add it to source control. The alternative would be: run makemigrations within the Dockerfile that builds the deployed image, however that could result in the same migration being run twice on the database should the name of that migration change (e.g. if there's a timestamp in the name). So I'm thinking best to avoid that. Note: this question is … -
django Imagefield accepting all files
In my registration page, I am able to input a file other than an image for example -.txt or .py then save it. Even though my model is an Imagefield it allows files other than images. I have other models with imagefield in them but they are working fine. When I try to save a txt or py file there it raises an error. But in my registration page it directly saves it. I have also added validators still does not work. Note that when I try to edit user from admin page there it raises an error. models.py : from django.contrib.auth.models import User from django.core.validators import validate_image_file_extension from django.db import models from django.utils import timezone from multiselectfield import MultiSelectField # Create your models here. class UserProfileInfo(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, help_text=False) profile_pic = models.ImageField(upload_to="profile_pic/",validators=[validate_image_file_extension], null=True , blank=True) def __str__(self): return self.user.username views.py def register(request): accounts = User.objects.all() if request.method == "POST": user_form = UserForm(data=request.POST) profile_form = UserProfileInfoForm(data=request.POST) if user_form.is_valid() and profile_form.is_valid(): user = user_form.save() user.set_password(user.password) user.is_active = False user.save() profile = profile_form.save(commit=False) profile.user = user if 'profile_pic' in request.FILES: profile.profile_pic = request.FILES['profile_pic'] profile.save() messages.success(request, 'Your account has been created Sucessfully!!!!') messages.success(request, 'You can use your account after it has … -
No Tag matches the given query. on localhost:8000/filter/en
I've been working on a project, where I want to filter a resource on a page by language. But everytime I use that filter, i'm getting redirected to a 404-Page. This is my View: class SomeView(LoggedUserWithOrganizationMixin, ListView): paginate_by = 12 def get_queryset(self): qs = Example.objects.all() selected_language = self.kwargs.get("selected_language",self.request.user.profile.language) return qs.filter(language = selected_language) This is my url in urls.py: path('<str:selected_language>/', views.SomeView.as_view(), name="list-lang-filter"), And this is my HTML-Code for the select where the user can pick the language: <div x-show="dropdownOpen" class="w-full absolute rounded border border-forblueshadow bg-white z-20 font-light text-brightblue pt-1"> {% for language in languages %} <a href="{% url 'list-lang-filter' current_organization.pk language.code %}" class="language_filter_dropdown rounded-t py-2 px-4 block whitespace-no-wrap"> {{ language.name }} </a> {% endfor %} </div> When choosing an option in the filter-menu, i get redirected to a url with the right language code in it, but it just shows a 404. The weird thing is i did the exact same thing on another resource and it worked just fine. Does anybody have an idea?
