DJango rest framework - API list using filter field from related models
Hi I'm new to Django and the Django rest framework so my terminology may be off. I'm trying to build an API that gives back a list of items from a model but filtered based on fields in another related model. I'll provide my current view and serializer classes and models class service(models.Model): name = models.CharField(max_length=50) vendor = models.CharField(max_length=50) version = models.CharField(max_length=10) registration_status = models.BooleanField(default=False) class service_network(models.Model): service = models.OneToOneField( service, related_name='network', on_delete=models.CASCADE, primary_key=True, ) forwarded_port = models.CharField(max_length=50) class ServiceNetworkSerializer(serializers.ModelSerializer): class Meta: model = service_network fields = '__all__' class ServiceSerializer(serializers.ModelSerializer): network = ServiceNetworkSerializer() class Meta: model = service fields = [ 'id', 'name', 'vendor', 'version', 'registration_status', 'network', ] class ServiceAPI(ModelViewSet): queryset = service.objects.all() serializer_class = ServiceSerializer filterset_fields = '__all__' Currently I can get back lists using a URL query string {{baseUrl}}/engine/service?registration_status=true What I want to do is something like this {{baseUrl}}/engine/service/network?farwarded_port=8080 Which I would expect to give back a list of services where the related network field "forwarded_port" is equal to 8080. Is there another way to query this API? Maybe using a POST with a body containing the query? If there something in the DOCS that I can read, I've tried to look through filtering and querysets but I … -

how to fetch parent table field value using queryset object in django template

Ajax success function does not triggered
i have a comment system in django. I am trying to make post request with ajax, information in the form stored in database, but ajax success function doesn't work. So, this is my ajax post method $('#parentComment').submit(function(e){ e.preventDefault(); const url = $(this).attr('action'); const btn = $('.comment-btn').attr('name'); const body = $('#parentCommentText').val(); $.ajax({ type: 'POST', url: url, data: { 'csrfmiddlewaretoken': $('input[name=csrfmiddlewaretoken]').val(), 'btn': btn, 'body': body, }, sucess: function(response){ console.log(response) }, error: function(response){ alert('error'); } }); }) So this is views.py file class Articlepage(View): def get(self, request, pk, *args, **kwargs): article = Articles.objects.get(id=pk) comments = article.messages_set.all() likes_count = article.likes.count() context = {'article': article, 'comments': comments, 'likes': likes_count} return render(request, 'base/main_article.html', context) def post(self, request, pk, *args, **kwargs): article = Articles.objects.get(id=pk) comments = article.messages_set.all() likes_count = article.likes.count() if 'parent-comment-submit' in request.POST['btn']: try: value = request.POST.get('parent') parent = Messages.objects.get(id=int(value)) except: parent = None body = request.POST.get('body') if body: comment = Messages.objects.create( user = request.user, article = article, parent = parent, body = body, ) return JsonResponse({'body': comment.body, 'user': comment.user.username, 'parent':parent}, safe=False) return JsonResponse({}, safe=False) -
Django Rest Framework - Way to make specific values within two columns in parent table a constraint to be only used together in child table as fk?
not sure I worded my question right in the title, let me try and explain better below... Let's say a parent table called Share has two columns, a ShareCode Charfield(primary key) and a ShareName unique Charfield (string). This means we'll have a unique ShareCode and ShareName paired on each row of this table. Code for this below. class Share(models.Model): ShareCode = models.CharField(max_length=100, primary_key=True, default="N/A") ShareName = models.CharField(max_length=100, unique=True, default="N/A") Now let's say we have a child table, Fund. This table will consist of a FundID Autofield(primary key), a FundCode Charfield, and a FundName CharField. It will also have two foreign keys that reference the Share table, ShareCode and Sharename. Finally, it will have two unique_together constraints, FundCode and ShareCode as the first constraint, and FundCode and ShareName as the second. Code below. class Fund(models.Model): FundID = models.AutoField(primary_key=True) FundCode = models.CharField(max_length=100, default="N/A") FundName = models.CharField(max_length=100, default="N/A") ShareCode = models.ForeignKey(Share, to_field='ShareCode', related_name='fundsShareCode', on_delete=models.CASCADE) ShareName = models.ForeignKey(Share, to_field='ShareName', related_name='fundsShareName', on_delete=models.CASCADE) class Meta: unique_together = ('FundCode', 'ShareCode'), unique_together = ('FundCode', 'ShareName') Couple of things to note at this point, let's imagine that every share that we could possibly need is already in the Share table. The fund table's data however is being manually input … -

How get # fragment values from the URL in Django
In my Django website, I want to redirect to an external website, authenticate on this external website and then the external website returns an API token that I want to save. I have instructed the external website to redirect to 127.0.0.1:8000 (my home page) after I have successfully authenticated. When I'm redirected, I have a URL in this format: http://127.0.0.1:8000/#access_token={token the external website generates}&token_type=Bearer&expires_in={expiry time}. How can I get the values after the # in the URL? As I understand the values after the # is not sent back to the Django server. -
Django Model.objects.last() returning second to last instance instead of the very last instance
I'm in the process of building a Django app, which is meant to be a self updating inventory app for a hypothetical restaurant. I have a model, "Purchase", which uses another model "Register" as a ForeignKey field. I have it set the reference to the last instance created of Register so that any entree purchase is linked to the currently active register at the store. The problem is that when a Purchase instance saves, it keeps referencing the second to last Register object instead of the last. Here is the current model code for those two models: class Register(models.Model): daily_bank = models.FloatField(default=500) amount_spent = models.FloatField(default=0) amount_made = models.FloatField(default=0) date = models.DateField(default=date.today) def sales(self): lst = [] for p in self.purchase_set.all(): if p.menu_item not in lst: lst.append([p.menu_item.title, 1]) else: for entry in lst: if entry[0] == p.menu_item.title: entry[1] = entry[1] + 1 return lst def profit(self): if self.id > 1: return self.daily_bank - Register.objects.get(id=self.id-1).daily_bank else: return self.daily_bank - 500 def last(self): return self == Register.objects.last() class Purchase(models.Model): menu_item = models.ForeignKey(MenuItem, on_delete=SET_NULL, null=True) time = models.DateField(default=datetime.now) item_name = models.CharField(max_length=100) register = models.ForeignKey(Register, on_delete=CASCADE, default=Register.objects.last()) def save(self, *args, **kwargs): self.item_name = self.menu_item.title if self.pk is None: for i in self.menu_item.reciperequirment_set.all(): if i.menu_item == … -
Steam API json output isn't being displayed cleanly
I've been trying to get the output from the steam API to display in my django app. My goal is to create a "portfolio" of games that I own for a project - using the information in the Steam API. I'm fairly new to Django, but know enough to be dangerous. Any help would be greatly appreciated, as I have been banging against this for a week... My question is, how does one pull specific items from the json and display the data correctly inside of the template? I cannot seem to loacte a tutorial that fits the schema of the output from this API. - any help (and a brief explanation maybe) would be greatly appreciated. For example, how can I capture the minimum system requirements from the API and display them in a div on my page? This is my views.py: def index(request): response = requests.get('https://store.steampowered.com/api/appdetails/?appids=218620').json() return render(request, 'index.html', {'response': response}) While it actually returns data, you'll notice that the data is littered with weird characters and such. Here is my index.html: {% extends 'base.html' %} {% block content %} {{response}} {% endblock %} if you add a 'safe' tag to the django template like this: {% extends … -

Disable Django default colored logs
I'm trying to take advantage of the default Django logging system and save those messages on a file. The only problem is that messages have color codes, that also get saved in the destination file handler. I added a custom file handler with a custom formatter to the "django" logger, but the message is still colored. I tried to debug a bit and I believe that there is some formatter working under the hood that add colors to the messages, since printing the messages received by my formatter shows that they already contain the color codes. I also tried creating a CustomServerFormatter which is a copy of django's default ServerFormatter (in which I saw the color codes were applied), but without the calls to add colors based on the HTTP response, but still no results. This is my current dictconfig: LOGGING = { "version": 1, "disable_existing_loggers": False, "filters": { "require_debug_false": { "()": "django.utils.log.RequireDebugFalse", }, "require_debug_true": { "()": "django.utils.log.RequireDebugTrue", }, }, "formatters": { "django.server": { "()": CustomServerFormatter, "format": "[{server_time}] {message}", "style": "{", }, "syslog_ws": { "()": SyslogFormatter, 'name': "webs" }, }, "handlers": { "console": { "level": "DEBUG", 'filters': ['require_debug_true'], "class": "logging.StreamHandler", }, "file": { "formatter": "syslog_ws", "level": "INFO", "class": "logging.handlers.RotatingFileHandler", "filename": … -

Unable to log msgs from Local Django apps to Console when using Docker
I have configured a Django project using cookiecutter-django. When I run this locally I don't see any log from my local Django Apps on the console.

Uploading files from the frontend to a file server with Python Django and SFTP
I would like to upload files from the frontend (vueJS) with axios to a remote file server. My backend is written in Python and I'm using the Django framework. I successfully uploaded files from the backend to the server with paramiko: sftpclient.put('localpath', 'remotepath') The problem is that it requires the file to be in the backend folder. How can I bypass that and upload the files from the client straight to the file server? I also tried using the django-storages package, but that puts the file in the RAM for some reason and uploads it really slow to the file server (and also crashes when I try it with large files). -
Django Static Files Duplicating when I run collectstatic using heroku's settings
I have a django project that recently started producing a lot of static files. When googling around it seems that I have some overlap in my STATICFILES_DIRS and STATIC_ROOT I followed Heroku's documentation on static files. I noticed it when switching between VScode and pycharm which I do not think could have caused this but I thought i would mention that as well. Pycharm just seems to ignore the 2600 "Unversioned Files" while vs code wants to push them all to github. I do not see the overlap in my static_root and static_dirs and at this point have spent enough time that I thought I would bring it here. Below I have attached images off the errors from heroku and well as the static portion of my settings.py file. Any suggestions of how to keep this from happening and get rid of these ugly bloating files would be greatly appreciated. This is my first deployed site so considering this is my biggest problem now I figure this is a success. But i want these files gone. I also just noticed that when I run mange.py runserver I get two lines of staticfiles -

How to dynamically insert a value in a Django ModelForm
I have a project where users can create a company. However, there is a Theme that needs to be dynamically inserted, once the user chooses a theme on the frontend - more like when you want to choose a template in a no-code builder. Below is my models.py class Theme(models.Model): name = models.CharField(max_length=100, null=True) image = models.ImageField(upload_to='static/images/themes_images', null=True, blank=True) category = models.CharField(max_length=200, choices=CATEGORY_CHOICES, null=True) class Company (models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE, null=True, editable=False) date_created = models.DateField(default=timezone.now, null=True) company_name = models.CharField(max_length=100, null=True) theme = models.ForeignKey(Theme, on_delete=models.CASCADE, null=True, blank=True) For the Theme model, it is only the administrator who will create it and the user will only have to choose it on the front end. Sort of like when choosing a premade template in Weebly. All the Theme Objects will have their own page where the user can visually see which theme to go with: @login_required(login_url='login') def theme(request): themes = Theme.objects.all() context = {'themes': themes} return render(request, 'themes.html', context) I haven't done much with the view, cause I am not sure how to go about it to achieve the desired result.

I just squashed a lot of migrations in Django 4.0.x. Now when running the migrations I get the following error: File "/opt/hostedtoolcache/Python/3.9.10/x64/lib/python3.9/site-packages/Django-4.0.3-py3.9.egg/django/db/migrations/loader.py", line 120, in load_disk migration_module = import_module(migration_path) File "/opt/hostedtoolcache/Python/3.9.10/x64/lib/python3.9/importlib/__init__.py", line 127, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "<frozen importlib._bootstrap>", line 1030, in _gcd_import File "<frozen importlib._bootstrap>", line 1007, in _find_and_load File "<frozen importlib._bootstrap>", line 986, in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 680, in _load_unlocked File "<frozen importlib._bootstrap_external>", line 846, in exec_module File "<frozen importlib._bootstrap_external>", line 983, in get_code File "<frozen importlib._bootstrap_external>", line 913, in source_to_code File "<frozen importlib._bootstrap>", line 228, in _call_with_frames_removed File "/home/runner/work/backend/backend/general/migrations/0001_squashed_0019_merge_0018_auto_20220226_2311_0018_auto_20220228_2343.py", line 42 code=general.migrations.0004_initial_general.Migration.load_data, ^ SyntaxError: invalid decimal literal The according code lines in the migration file is: migrations.RunPython( code=general.migrations.0004_initial_general.Migration.load_data, ), I am totally lost here.
