How to sync local Django sqlite3 data with Heroku's postgres database?
I have a Django website served by Heroku with a model storing data about projects that I've worked on in the past. I already ran makemigrations and migrate locally before pushing to heroku with git and running heroku run python3 manage.py migrate. So, my database models and fields are synced, but I'm asking about the field values. Whenever I update the value of a field for a model instance locally, I want it (the data) to sync with Heroku, and vice versa–sync values I've updated on Heroku in the admin panel with my local sqlite3 database. Is there a command for updating the values of the database itself, or am I missing something? Because I've looked all over the internet for the last hour for how to do this one thing. Side note: I also want the command I'm looking for to sync newly created instances, not just data for existing model instances. -

Django template won't render form errors
After a user has submitted a form with data that fails validation, form.errors in fact collects those errors as I've been debugging the issue. However when I render the page after a POST request, the errors will not be parsed in HTML alongside the fields where errors occur. What needs to change in order for the validation errors to render in the template when user data doesn't pass validation? # view that renders the template @login_required(login_url="/accounts/sign_in/") def new_profile(request, username): form = ProfileForm() import pdb; pdb.set_trace() if request.method == 'POST': user_profile = ProfileForm(request.POST) if user_profile.is_valid(): user_profile.cleaned_data.update(user=request.user) Profile.objects.create(**user_profile.cleaned_data) return HttpResponseRedirect( reverse("accounts:profile", kwargs={'username': username}) ) return render(request, 'accounts/create_profile.html', {'form': form}) # create_profile.html {% extends 'layout.html' %} {% block body %} <form action="{% url 'accounts:new_profile' username=user %}" method="post"> {% csrf_token %} {{ form }} <button type="submit">Submit</button> </form> {% endblock %} -> if request.method == 'POST': (Pdb) n -> user_profile = ProfileForm(request.POST) (Pdb) n -> if user_profile.is_valid(): (Pdb) p user_profile.errors {'birth': ['Enter a valid date.'], 'bio': ['Add more detail to your bio.']} -

Plotting a timestamp with django and matplotlib
I'm having some trouble creating a view in django, I'm trying to make a web app which will read in from a csv and then display the plot, however the time axis I need to plot from the csv is not a float it is a string, then way I have it here I'm not sure how to plot this timestamp: def showMe(request): fig = Figure() canvas = FigureCanvas(fig) x, y = np.loadtxt('/Users/name/Desktop/garden_app/stored.csv', delimiter=',', dtype={'names': ('time','moisture'), 'formats': ('|S1', np.float)}, unpack=True) plt.plot(x, y, align='center', alpha=0.5, label='Name') plt.ylabel('moisture') plt.xlabel('time') plt.title('Moisture V.

Bulk Update of model fields baseds on user input in admin site
In django, let's say I have a model with an integerfield called "RouteNumber" in my model. I manage all the model entries in the django admin site and I want to assign a route number to more than 100 entries at a time. How can I do that based on a user input? I was thinking using an admin action that would request a number and that all the queryset would be assigned this value In my model.py: class Person(models.Model): Name = models.CharField("Nom du parent", max_length=40, default="") RouteNumber= models.IntegerField("Numéro de route", default=None, blank=True, null=True) In my admin.py: def assign_route_number # This is where I'm lost ==== number = user_input("Enter a route number") # ======== for obj in queryset: obj.RouteNumber = number obj.save() However I don't know how to get the user input. Is there an easy way to get that? Thank you for your answers -

Slow Django Page - Doesn't Appear to be caused by SQL
I'm trying to debug a slow Django listview page. The page currently displays all tests (133), as well as the latest result for each test. There are approximately 60,000 results, each result having a FK relationship to a single test. I've optimized the SQL (I think) by selecting the latest result for each test, and passing it in as a prefetch related to my tests query. Django Debug Toolbar shows that the SQL is taking ~350ms, but the page load is ~3.5s. If I restrict the list view to a single test though, the SQL is ~7.5ms, and page load is ~100ms. I'm not fetching anything from S3 etc, and not rendering any images or the like. So my question is, what could be causing the slowness? It seems like it is the SQL, since as the result set grows so does page load, but maybe rendering of each item or something similar? Any guidance on what to look into next would be appreciated. -

How to properly filter or exclude based on a parameter in Django?
I can do this in Django: query = {field_name: value} if include: return queryset.filter(**query) else: return queryset.exclude(**query) That's bad because there's a fair bit of duplication, and it's rather verbose. I can also do this, which is much simpler: return queryset._filter_or_exclude(not include, field_name=value) But that's also bad, because I'm calling a protected method. Is there a way to combine the best of both? return queryset.filter(exclude=not include, field_name=value) is not a thing. -
How do I get a specific value from an object through foreign key connection in django?
guys! I got the following table and want to get all scad files from objects of Model3D where part of is not null and has the same id as Model3D.

VS Code: Python Interpreter can't find my venv
I've been stuck on this for a few days, kindly help me if you can. I have my venv folder on my root project folder. When I try to set the Python Interpreter, it shows me only the Python installed in my machine and not the one in my root folder. It was working fine until I formatted my PC and installed windows 10 64 bits. (was running on windows 7 64 bits prior) Things I have tried: Set the path manually via pythonPath and/or venvPath, in both workspace and user settings: "python.pythonPath": "F:/Web Dev/Python/Django/project_x_v2/backend/venv/Scripts/python.exe", "python.venvPath": "F:/Web Dev/Python/Django/project_x_v2/backend/venv/Scripts/python.exe", It shows me the correct location in the placeholder but I don't have the option to choose it from the dropdown list: Any ideas how I can solve this?

Confused with multiple dimension dictionaries

How do I auto increment field that is part of unique_together in Django admin
Basketball Game has 4 Quarters. I would like Django to auto increment Quarter.number for each Game in Admin, so I don't have to always correct them manually. Example models.py class Game(models.Model): name = models.CharField() class Quarter(models.Model): number = models.IntegerField(help_text='quarter number from 1 to 4') game = models.ForeignKey(Game) class Meta: unique_together = ['game', 'number'] So number in Quarter can be 1, 2, 3 or 4 (or more for other sports) and should be set to 1 by default. After saving first quarter for one Game it should suggest number=2 for the next entry of the same Game. The incremented numbers should also get shown correctly in admin.TabularInline if I set Quarter as inline of Game in admin.py (in below code Django would by default show 3 entries for a new Game, but all would have default number=1): class QuarterInline(admin.TabularInline): model = Quarter class Game(admin.ModelAdmin): inlines = [QuarterInline] How can I achieve that number gets incremented by default for each game? -
Is there a way for Django to accept naive datetimes with USE_TZ=True, or to suppress warnings?
Our company has been a long-time user of Django -- for more than 10 years. We are currently running Django 1.11.26. We've dealt with a lot of datetime-related issues over the years, but our current issue is proving challenging. Our goal is to do the following: use Django's timezone support (setting USE_TZ=True) with UTC as default time zone for a couple of denormalized fields (daily rollups of energy data) store naive datetimes As is documented in many Stack Overflow questions, Django will issue a warning with datetime field values set to a naive datetime: RuntimeWarning: DateTimeField received a naive datetime...while time zone support is active. We think our use case for storing naive datetime is a reasonable one. While for almost all our datetime fields it make sense to use UTC, for certain kinds of daily rollups we want to store a naive/agnostic datetime indicating the start datetime of the day in the local time zone (multiple time zones for different objects). By using a naive datetime, we are able to use datetime-related filters. Therefore if we are summarizing certain kinds of energy rollups for a given datetime, we can find the rollup for the same local datetime for buildings …
