Django select from many-to-many
The basic model. class Game(models.Model): date = models.DateField() ... class Player(models.Model): user = models.OneToOneField(User, default=None, on_delete=models.CASCADE) games = models.ManyToManyField(Game, through='PlayerGame') ... class PlayerGame(models.Model): player = models.ForeignKey(Player, on_delete=models.CASCADE) game = models.ForeignKey(Game, on_delete=models.CASCADE) score = models.IntegerField() ... Each game will have two players with their respective scores. When one player/user is logged in, I'd like to display all their games against other players. e.g. Player 1 logged in... Date Opponent Your Score Opponent Score 2022-01-01 Player 2 31 27 2021-06-02 Player 4 31 26 2021-06-02 Player 2 5 31 2021-05-27 Player 6 20 31 If Player 2 was logged in, they may see Date Opponent Your Score Opponent Score 2022-01-01 Player 1 27 31 2021-06-02 Player 1 31 5 Any ideas on how to write a query for this? -
Django and adding a static image
Good evening, I've just completed this tutorial: https://docs.djangoproject.com/en/4.1/intro/tutorial01/ and I need to add a new directory to display a dataset (unrelated to the polls app) I've set up my new directory as I did the first steps in the tutorial. My steps: ...\> py manage.py startapp newendpoint newendpoint/ __init__.py admin.py apps.py migrations/ __init__.py models.py tests.py urls.py views.py path('newendpoint/', include('newendpoint.urls')) **Once this is setup I've tried these tutorials: ** https://youtu.be/u1FR1nZ6Ng4 I've tried this tutorial and had no luck https://adiramadhan17.medium.com/django-load-image-from-static-directory-27f002b1bdf1 I've also tried this one My server goes down or nothing displays. I could really use some help getting this figured out, before I tried the static image I was trying to add a csv via SQLite3 with no luck either. -
How do I overwrite Bootstrap SCSS variables for my django website using PyCharm?
I'm using PyCharm to manage my django files and for the front end I'm using Bootstrap. I'm currently using the CDN method to point to the bootstrap files in my base.html file. I've recently come to a point where I want to customize some of the SCSS variables that bootstrap provides, but I'm puzzled and can't find a guide anywhere to how to do this with my configuration. I used npm to install the bootstrap files to my outer project folder. I've tried installing django-sass-compiler using pip, and then adding the required setting to my settings.py, but when I ran the command "python manage.py sass-compiler" (as per the PyPi docs), I got "ModuleNotFoundError: No module named 'django_sass_compiler'" I'm assuming that if I were to get that working then it would compile my custom SCSS file into a CSS file that would overwrite my current 'main.css' (is that right?), however I can't even figure out that part. If someone could please point me in the right direction then that would be great, there really isn't a lot of help out there for sass, pycharm, django & bootstrap together. -

In Django, how to make a join query with matching conditions in addition to the foreign key?
We have a hand-written SQL query for proof of concept and hope to implement the function with the Django framework. Specifically, Django's QuerySet usually implements a join query by matching the foreign key with the primary key of the referred table. However, in the sample SQL below, we need additional matching conditions besides the foreign key, like the eav_phone.attribute_id = 122 in the example snippet below. ... left outer join eav_value as eav_postalcode on t.id = eav_postalcode.entity_id and eav_phone.attribute_id = 122 ... Question: We wonder if there is a way to do it with the Django framework or libraries. Technical Details: The scenario is a report that consists of transactions with customized columns by Django-EAV. This library implements the eav_value table consists of columns of different data types, e.g. value_text, value_date, value_float, etc. So, the application defines a product with attributes in specific data types, and we referred it as metadata in this question, e.g.: attribute_id slug datatype 122 postalcode text 123 phone text ... ... e.g. date, float, etc. ... We are using a forked reposition of Django-EAV, not Django-EAV2, but the new version follows the same database schema design as far as we know. So, one transaction is … -

How to Create a Pandas DataFrame from multiple list of dictionaries
I want to create a pandas dataframe using the two list of dictionaries below: "country_codes": [ { "id": 92, "name": "93", "position": 1, "description": "Afghanistan" }, { "id": 93, "name": "355", "position": 2, "description": "Albania" }, { "id": 94, "name": "213", "position": 3, "description": "Algeria" }, { "id": 95, "name": "1-684", "position": 4, "description": "American Samoa" } ] gender = [ { "id": 1, "name": "Female" }, { "id": 3 "name": "Male" } ] The dataframe should have two columns: Gender and Country Code.

How to get reference table fields with django model query

Django query to return percentage of a users with a post
Two models Users (built-in) and Posts: class Post(models.Model): post_date = models.DateTimeField(default=timezone.now) user = models.ForeignKey(User, on_delete=models.CASCADE, null=True, related_name='user_post') post = models.CharField(max_length=100) I want to have an API endpoint that returns the percentage of users that have posted. Basically I want SUM(unique users who have posted) / total_users I have been trying to play around with annotate and aggregate, but I am getting the sum of posts for each users, or the sum of users per post (which is one...). How can I get the sum of posts returned with unique users, divide that by user.count and return? I feel like I am missing something silly but my brain has gone to mush staring at this. class PostParticipationAPIView(generics.ListAPIView): queryset = Post.objects.all() serializer_class = PostSerializer def get_queryset(self): start_date = self.request.query_params.get('start_date') end_date = self.request.query_params.get('end_date') # How can I take something like this, divide it by User.objects.all().count() * 100, and assign it to something to return as the queryset? queryset = Post.objects.filter(post_date__gte=start_date, post_date__lte=end_date).distinct('user').count() return queryset My goal is to end up with the endpoint like: { total_participation: 97.3 } Thanks for any guidance.

How do I make a post request work after using get_queryset?
I would like to have a list of a user's devices with a checkbox next to each one. The user can select the devices they want to view on a map by clicking on the corresponding checkboxes then clicking a submit button. I am not including the mapping portion in this question, because I plan to work that out later. The step that is causing problems right now is trying to use a post request. To have the user only be able to see the devices that are assigned to them I am using the get_queryset method. I have seen a couple questions regarding using a post request along with the get_queryset method, but they do not seem to work for me. Using the view below, when I select a checkbox and then click submit, it looks like a post request happens followed immediately by a get request and the result is my table is empty when the page loads. Portion of my views.py file: class DeviceListView(LoginRequiredMixin, ListView): model = Device template_name = 'tracking/home.html' context_object_name = 'devices' # ordering = ['-date_added'] def get_queryset(self, *args, **kwargs): return super().get_queryset(*args, **kwargs).filter(who_added=self.request.user) def post(self, request): form = SelectForm(request.POST) # if form.is_valid(): # text = … -

Ignore a line of Javascript if the element isn't present on the page and skip to the next line?
Working on a django web app and running into an issue with my javascript. The web application is multiple different html pages, so the elements my js code is searching for are present on some pages but not others. If the second line is not present on the current page, the script stops running and the final function will not work. I have a "plan" page where you can add additional tags to your plan and then a separate page to filter results. If I'm on the plan page then the "#filterBtn" element is not present so my createNewTagField function doesn't work. If I switch the two lines of code, the opposite happens. I can't get them both to work since the elements javascript is searching for are on two different pages and not present at the same time. These are the lines causing problems. document.addEventListener('DOMContentLoaded', function() { document.querySelector('#mobile-menu').onclick = toggleMobileMenu; document.querySelector('#filterBtn').onclick = toggleFiltersMenu; document.querySelector('#addTag').onclick = createNewTagField; }); I've rearranged the lines of code and it just fixes it for one page while still having the problem on the other page. I'm thinking it needs to be something like if null then continue to the next line, but haven't been … -
Does OpenXML SDK only work with Visual Studio?
I am creating a Django application to be run on an IIS server. I need to update an Excel file automatically on the server. Given that the interactive update using COM (pywin32.com) is not supported by Microsoft (https://support.microsoft.com/en-us/topic/considerations-for-server-side-automation-of-office-48bcfe93-8a89-47f1-0bce-017433ad79e2) I need to use the Microsoft recommended approach which involves using OpenXML SDK. In the following link, https://learn.microsoft.com/en-us/office/open-xml/getting-started, it mentions this is used with Visual Studio. My question is whether this is the only way of using OpenXML SDK to edit Office documents. I do not use Visual Studio.

Use two different REST API back-end systems for one app/front-end [closed]
So basically I currently have a web app project with the front-end being Next.js (React/JS) and the back-end being Laravel (PHP). When development started Laravel was chosen by the developers and I was okay with that, since I was not really into back-ends, and heard that Laravel is alright. But from there on, along with them developing the project I started learning Javascript, React etc, and right now I am working on the project mostly by myself, because with my current skill I am now capable of doing most front-end related things, and I am also a bit familiar with Laravel at this point. Though currently I want to take a deeper dive into Node.js or Django and here comes my question with that. I would like to build to extend my web app with another integrated area in it, with some completely other functionality that is completely decoupled from the existing Laravel REST API. The current REST API just sends Json to the front-end, requested through axios with a simple rest url. As a practice project I wanted to build a new REST API for this new part of the web app in Django/Node all by myself, and the … -
Django: How to specify a URL as a slug in django template?
I am trying to create a django template that has links to other pages (in particular static images, each with their own html template), but I am trying to move away from hardcoding a url and view for each one, instead I want to capture them all with a general slug URL, and a view that takes the slug as input. My slug URL in urls.py is working fine, when I manually input the slug field in the full URL it links to the correct template and directs me to the correct page. However when I try to reference any of links as slugs from the 'cside' template I keep getting the error: NoReverseMatch at /plots/cside Reverse for '2E_C' not found. '2E_C' is not a valid view function or pattern name. Basically, I want the 'cside' page to have links that are slugs. Can anyone tell me what I am missing, I have tried everything! Here is my urls.py from django.urls import re_path, path from django.contrib.staticfiles.urls import staticfiles_urlpatterns from . import views from .views import mode urlpatterns = [ re_path(r'^cside$', views.cside, name='cside'), re_path(r'^lside$', views.lside, name='lside'), re_path(r'^home$', views.home, name='home'), #re_path(r'^2E_C$', views.m2E_C), re_path(r'^4M_C$', views.m4M_C), re_path(r'^6E_C$', views.m6E_C), re_path(r'^6M_C$', views.m6M_C), re_path(r'^8E_C$', views.m8E_C), re_path(r'^2E_L$', views.m2E_L), … -
__init__.py issue in django test
I have an issue with running a test in my Django project, using the command python manage.py test. It shows: user:~/workspace/connector$ docker-compose run --rm app sh -c "python manage.py test" Creating connector_app_run ... done Found 0 test(s). System check identified no issues (0 silenced). ---------------------------------------------------------------------- Ran 0 tests in 0.000s OK I was debugging it and I know that it's probably a "init.py" file. If I'm deleting file init.py from app.app (I have read somewhere that it can help) then I'm receiving an error: ====================================================================== ERROR: app.tests.test_secrets (unittest.loader._FailedTest) ---------------------------------------------------------------------- ImportError: Failed to import test module: app.tests.test_secrets Traceback (most recent call last): File "/usr/local/lib/python3.9/unittest/loader.py", line 436, in _find_test_path module = self._get_module_from_name(name) File "/usr/local/lib/python3.9/unittest/loader.py", line 377, in _get_module_from_name __import__(name) File "/app/app/tests/test_secrets.py", line 12, in <module> from app.app import secrets ModuleNotFoundError: No module named 'app.app' why did this error occur? Pycharm projects normally see import and what I know from version 3.4 it's not obligatory to put init.py into folders to make the package. This is the github link: https://github.com/MrHarvvey/connector.git Can you explain me what I'm I doing wrong here?
