How to add a button in a django list to add List's data to a HTML TextField?
I'm looking for the best implementation of adding data to view from the Django model in a list rendered in a template with the help of a button that sits along with other data on every row.

Is there a standard practice for storing flat data files that are used for testing in a Django project?
I'm unit testing the way that my Django application loads and processes various flat files and I'm having trouble deciding where to store the files that contain the data for these tests. Is there a standard practice or location for this? Would it make more sense to store these files in one of the STATICFILES_DIRS or in a subdirectory of MEDIA_ROOT, or some other directory? If some other directory, how might that be configured in the settings module? For example: from pathlib import Path from django.core.files.uploadedfile import SimpleUploadedFile from django.test import TestCase def simulate_uploaded_file(data_path: Path, filename: str) content_type = get_content_type(filename) filepath = data_path / filename content = open(filepath, 'rb').read() data_file = SimpleUploadedFile(data_file_path, content, content_type) class TestFileHandler(TestCase): @classmethod def setUpTestData(cls): test_data_path: Path = settings.TEST_DATA_DIR # <- IS THERE A STANDARD LOCATION FOR THIS? cls.valid_csv: SimpleUploadedFile = simulate_uploaded_data(test_data_path, 'filename.csv') -
INSERT, REPLACE, UPDATE not working in Python and SQLite with Django Framework
What I am using I am using python codes to access a database with multiple tables in SQLite. All this is done in Linux's Ubuntu OS The Problem The problem is that I am unable to UPDATE, INSERT, REPLACE data in one of the tables through python codes but DELETE works just fine, meaning I am able to delete a specific row in the table. For reference, when using the same commands for another table, it works fine. What I have done I have used .commit() in python, but the codes do not commit. To see if these commands work in the database itself, in case there were unknown permissions set, I used DB Browser for SQLite and they do work when done directly through the database. Any idea if there might be any explicit permissions set to each command in SQLite or is there any other cause for this? And are there any suggestions as to what I should do to check? -

DoesNotExist at /nuevo/ Profile matching query does not exist

Join 2 tables over 2 columns in django
I have a database imported from mysql in models.py like : class Sig(models.Model): id = models.IntegerField(db_column='Id', primary_key=True) proportion = models.FloatField(db_column='Prop', blank=True, null=True) marine_area = models.CharField(db_column='Marine_Area', max_length=255, blank=True, null=True) habitat = models.CharField(db_column='Habitat', max_length=255, blank=True, null=True) This one doesn't have any coordinates associated. The coordinates are in another table : class Coord(models.Model): id = models.IntegerField(db_column='Id', primary_key=True) marine_area = models.CharField(db_column='Marine_Area', max_length=255, blank=True, null=True) habitat = models.CharField(db_column='Habitat', max_length=255, blank=True, null=True) latitude = models.FloatField(db_column='Latitude', blank=True, null=True) longitude = models.FloatField(db_column='Longitude', blank=True, null=True) I want to visualized my proportions according to their coordinates (latitude and longitude). However, each localisation is define with a marine area and an habitat (each marine area has 3 habitats) for ex So how can I create a new column with the concatenation of marine area and habitat to be able to join my two tables ? or is there any other solution to join my two tables ?

Django Ckeditor Automatically Save Data to Server / Backend
How would I go about automatically saving data from frontend ckeditor to the backend without reloading the page. I tried using ajax to make this work, but I am unable to send the updated content to the backend. Additionally, the javascript on change method is triggering 2x per single input. For example if I type "A" for a new input in ckeditor, it'll trigger twice for some unknown reason. Approach 1 - HTML / JS (Click "submit" button when change is detected) <form class="pt-2" action="#" method="POST" id="designer-form"> {% csrf_token %} {{ form.media }} {% for field in form %} {{ field }} {% endfor %} <div class="mt-4 flex justify-end space-x-4"> <button type="submit" id="submit"> Save Changes </button> </div> </form> <script> CKEDITOR.on('instanceCreated', function(event) { let editor = event.editor; editor.on('change', function() { setTimeout(function () { document.getElementById("submit").click(); }, 2500); }); }); </script> Approach 2 - HTML / JS (Serialize Data) <form class="pt-2" action="#" method="POST" id="designer-form"> {% csrf_token %} {{ form.media }} {% for field in form %} {{ field }} {% endfor %} <div class="mt-4 flex justify-end space-x-4"> <button type="submit" id="submit"> Save Changes </button> </div> </form> <script> CKEDITOR.on('instanceCreated', function(event) { let editor = event.editor; editor.on('change', function() { let data = editor.getData(); setTimeout(function (){ $.ajax({ … -
Check user doesn't already have this object before displaying CreateView - Prevent them from creating multiples
I've been slowly learning Django over the past few weeks, and applying it to a work prototype. I have a simple profile model called Applicant. This stores personal fields for the a customer. It contains a OnetoOne field linking to the Django Auth User model, as I'm using this to require login and control access to data. I'm struggling to figure out how to perform checks within View Classes (seemed easier within View Functions), I need a way to check if a user already has an Applicant entry before presenting them with the CreateView form. Previously to display this Applicant profile data (created via admin page), I used the get_object_or_404 within the DetailView.get_object to catch Http404 and return None if they didn't have a profile. This would then provide a link to the Create page. I need to implement the reversed logic on the CreateView, to protect them from creating multiple Applicant entries. Any suggestions would be great, even just to point me in the right direction. Code I used for DetailView: class ApplicantProfileDetailView(LoginRequiredMixin, generic.DetailView): model = Applicant template_name ='profile.html' def get_object(self, queryset=None): try: return get_object_or_404(Applicant, user=self.request.user) except Http404: return None <h1>Applicant Profile</h1> {% if applicant %} ... {% else … -
Letting the user Select a Font-Family in Django Web Application
I am in the process of building a Django Web Application that lets a user customize different CSS options for their webpage in the Django Admin Web Interface. Currently, the admin user has the option to change the color, background-color, and font-family. I used Django forms to create a Color Selector Widget so the user doesn't have to type in a hex color value and type in the name of a font. I am trying to create a widget to let the user select a font from a list of font-familys. I've looked into tkinter and listboxes but it appears it is best for GUIs. Should I just create a list of choices and populate it with a bunch of fonts? I have been having a hard time coming up with a viable efficient option. forms.py class cssForm(ModelForm): class Meta: model = styleEditor fields = "__all__" widgets = { "Link_Color": TextInput(attrs={"type": "color"}), "Link_Background_Color": TextInput(attrs={"type": "color"}), } models.py class styleEditor(models.Model): Link_Color = models.CharField(max_length=7, default="#000000") Link_Font_Style = models.CharField(max_length=15, default="Brush Script MT") Link_Background_Color = models.CharField(max_length=7, default="#F5F5F5") admin.py @admin.register(styleEditor) class styleEditor(admin.ModelAdmin): form = cssForm -
Django how to compere calculated fields in query
Is it possible to get data from another table in a query by comparing calculated values? Like for example, by calculating using the minimum and maximum price values and getting Url's to them from another table. My models look like this: class Product(models.Model): id = models.CharField(..) price = models.FloatField(..) url = models.CharField(..) ..... class ProductHistory(models.Model): ProductID = models.ForeignKey(Product, on_delete=models.CASCADE, to_field='ProductID', db_column='ProductID') price = models.FloatField(..) date = models.DateTimeField(..) My request looks like this query = HistoryPrice.objects.filter(ProductID=products).filter(query_price) \ .annotate(dt=Trunc('StartDate', frequency)) \ .values('dt') \ .annotate(max_price=Max('Price'), min_price=Min('Price')) \ .order_by('dt') But i want to get Url from Product table for each max_price for given period.

Uploading fixtures to django running within docker container in an AWS EC2 instance
So I have a a few operations I need to perform on a running instance - kind of a one-off thing. That involves uploading fixtures to it. The structure is an aws ec2 instance, on which runs a few docker container, including a django container. This the docker container in which I need to upload fixtures. This is all part of a ci/cd pipeline, with a postgres RDS database, nginx proxy, and the django container. I can scp the fixtures into the AWS EC2 instance. Then I can SSH into the EC2 instance, and from there log into the running container (using docker exec). That's all fine, but.... How can I access the fixtures that I uploaded to the ec2 instance (the docker host) from within the docker-container? Note: I'm aware I could commit the fixtures to git, then they would find their way into the docker image and be readily available there. I possible I'd rather scp them directly to ec2 & manage them in command lines (because small changes might be needed to the fixtures, which then means I have to run the whole pipeline and wait a few minutes each time...) -
Django Rest Framework Copeapi LinkLookupError
I am getting a LinkLookupError when trying to get a endpoint served by Django Rest Framework. This error only occurs after a single successfully request. My DRF view.py looks like: class RecordViewSet(viewsets.ReadOnlyModelViewSet): """ API endpoint that allows Records to be viewed or edited. """ filter_backends = (SimpleRecordFilterBackend,) serializer_class = RecordSerializer permission_classes = (IsAuthenticated,) @action(detail=False, url_path='tagsum/(?P<account>[^/.]+)/(?P<tag>[^/.]+)') def tagsum(self, request, account, tag): if not account or not tag: return Response({'status': "need accoutn and tag"}) sum = Records.objects.filter(linkedaccount_id=account).filter(user_project=tag).aggregate(total=Sum('unblendedcost')) return Response({'sum': sum['total']}) def get_queryset(self): q = Q() linkedaccount_id = self.request.query_params.get("linkedaccount_id") or '' user_project = self.request.query_params.get("user_project") or '' if linkedaccount_id: q &= Q(linkedaccount_id=linkedaccount_id) if user_project: q &= Q(user_project=user_project) return Records.objects.filter(q).annotate(Sum('unblendedcost')) After modifying the view file, I call $coreapi get http://localhost:8000/api/docs/ and see: ... records: { list([page], [linkedaccount_id], [productname], [user_project]) tagsum(account, tag) read(id, [linkedaccount_id], [productname], [user_project]) } ... and after one page load that calls that endpoint, when I run the same command I see this output: ... records: { tagsum: { read(account, tag) } list([page], [linkedaccount_id], [productname], [user_project]) read(id, [linkedaccount_id], [productname], [user_project]) } ... Note that the tagsum method now has the read method nested. Calls to the endpoint now return the following error. errors.js:10 Uncaught LinkLookupError: Invalid link lookup: ["records","tagsum"] at new LinkLookupError (errors.js:10) … -

Optimizing queries with Django ORM
I am using debug-toolbar to see the number of overall queries. The problem is that when I reload the page, I see different number of overall queries, given the same code and very short period of page reload intervals. I understand this is somehow related to caching. The question is, is there any shortcut to make Django at least in the debug mode always run all the queries so that I can see the real impact of my changes in the code ?
