Django Rest Framework how do I get the id I use in the URL
I have this serializer and I use it to get post detail of a post belonging to a user. The owner of the post is not the user that is currently logged in. I want to check if the post is bookmarked by the currently logged in user. The currently logged in user's id is passed in the request but I cannot find it in this context. Here is the serializer: class UserPostSerializer(serializers.ModelSerializer): images = PostImageSerializer(many=True, read_only=True, required=False) profile = serializers.SerializerMethodField() bookmarked = serializers.SerializerMethodField() class Meta: model = Post fields = [ "id", "category", "body", "images", "video", "profile", "published", "bookmarked", "created_at", "updated_at", ] depth=1 def get_profile(self, obj): profile_obj = Profile.objects.get(id=obj.user.profile.id) profile = ShortProfileSerializer(profile_obj) return profile.data def get_bookmarked(self, obj): breakpoint() bookmark = Bookmark.objects.filter(owner=obj.user.id, post=obj.id,marktype='post') if bookmark: return True else: return False The problem is obj.user.id is the owner of the post. I need the logged in user whose id is passed in the url. Here is the model for the bookmark: class Bookmark(models.Model): marktype = models.CharField(max_length=50) post = models.OneToOneField(Post, on_delete=models.CASCADE, null=True, blank=True) owner = models.ForeignKey(User, on_delete=models.CASCADE) created_at = models.DateTimeField(auto_now_add=True, verbose_name="created at") updated_at = models.DateTimeField(auto_now=True, verbose_name="updated at") class Meta: verbose_name = "bookmark" verbose_name_plural = "bookmarks" ordering = ["created_at"] db_table = "bookmarks" def … -
Why does this test keep failing?

Rollup Not Tree Shaking D3.js Correctly, Even With sideEffects Flag Set To False?
When using rollup v3 to bundle my npm project that uses the D3.js v7 library to an es6 module for use on the browser, I am ending up with a lot of extra unnecessary code from D3.js in the produced bundle. This happens even with the sideEffects flag set to false in package.json, which seemed to be the solution to this issue when it was discussed a couple of years ago on this github issue: https://github.com/d3/d3/issues/3076 . While treeshaking is definitely occuring, I'm still ending up with almost 1000 lines of code in my bundle from just importing one function (select from d3-selection). Besides setting the sideEffects flag to false in package.json, is there anything else I need to do? I also tried setting moduleSideEffects to false in rollup.config, but this didn't seem to have any additional effect. I have created a very simple example npm project that reproduces the issue. It is on github here: https://github.com/SpechtacularDave/rollupd3treeshake , or you can view the the example input index.js, package.json, and rollup.config.js below (but see the repo if you want to take a look at the output bundle since it's almost 1000 lines long). // index.js import {select} from "d3-selection"; select('#someid'); // … -
How are environment variables processed from ".env" file if Django project deployed to AWS from Github?
I have a Django project deployed on AWS EBS from a Github repo. My secret key is kept on a .env file. I've included the following: settings.py from decouple import config "SECRET_KEY" = config.("MY_SECRET_KEY") requirements.txt python-decouple==3.7 .env MY_SECRET_KEY = "THISISMYSECRETKEY-THISISMYSECRETKEY-THISISMYSECRETKEY" Since I've include .env inside my .gitignore file, the .env is not being pushed to Github. When I try to deploy my project I keep getting an error: "web: decouple.UndefinedValueError: SECRET_KEY not found". The project runs fine on a local server. Any advice would be appreciated. -

How could I configure it so that the user who is logging in is a user of a PostgreSQL database manager?
I am developing a web application, I would like to know how I can configure it so that the user who is logging in is a user of the PostgreSQL database manager, generally there is a superuser who has permissions to freely manage all the databases, but other users with a lower hierarchy can be added, so I would like it to be possible to access as such with those users created in the DBMS. I use python as programming language and django as framework. I really have no idea how to achieve this functionality, I'm starting my studies, I want to surprise my database teacher with something different from the rest of the students, and I would like someone to help me with this, I don't expect a complete solution, just a guide and references to be able to achieve what is proposed -
How to insert data in specific category if it is not defined in Django model's field?
I have a Django project where I created two models: Category and Shop. Each shop might have only one category. If I didn't define a shop's category I want it to be in Without category section at template. How do I set a default value? My models: class Category(models.Model): name = models.CharField(max_length=100) position = models.IntegerField(unique=True) def __str__(self): return f'{self.name}' class DemoShop(models.Model): title = models.CharField(max_length=100) category = models.ForeignKey(Category, on_delete=models.CASCADE, related_name='Cat') def __str__(self): return f"{self.title}" When I write: category = models.ForeignKey(Category, on_delete=models.CASCADE, related_name='Cat', default='Without category') It has no effect in my database and It doesn't show in Without category section at my template. If I haven't put a shop in a certain category I want it to be shown in Without category at the page, like: Products: -lorem; -testshop; Watch: -keram; -pollop; Without category: (All shop what I haven't define a category in DB) -
Why is Django check_password=True but authenticate=None
I'm trying to write a unit test for a login endpoint in Django using as much of the built in functionality as possible. There are existing tests that confirm that the account create endpoint is functioning properly. In the login view, however, the check_password() function will return True for this test, but the authenticate() function returns None. Is it safe to use the check_password() function instead? Otherwise, how do I update this code to use the authenticate() function? accounts.py class Account(AbstractUser): username = models.CharField(max_length=150, unique=True, null=False, default='') password = models.CharField(max_length=100) ... REQUIRED_FIELDS = ['email', 'password'] class Meta: app_label = 'accounts' db_table = 'accounts_account' objects = models.Manager() test_login.py def test_login(self): # Create account request_create = self.factory.post('/accounts/account', self.request_data, content_type='application/json') view = AccountView.as_view() response_create = view(request_create) # Login account request_login = self.factory.post('/accounts/login', self.request_data, content_type='application/json') view = LoginView.as_view() response = view(request_login) views.py class LoginView(View): def post(self, request): r = json.loads(request.body) email = r.get('email') password = r.get('password') cp = check_password(password, Account.objects.get(email=email).password) user = authenticate(username=email, password=password) P.S.

Django ORM Cast() returning double quoted string from JSON field
I need to annotate a value that is saved in a json field in the same model. (Not the smartest but it is what it is). I am annotating the value as such: Model.queryset.annotate( reference=Cast( F("reference_numbers__some_id"), output_field=models.CharField(), ) ) I need it to be cast to text/char in the query because a subsequent search will only work on text/char (trigram similarity). It works, sort of, but the result adds an extra quote to my string. Like so: queryset[0].reference -> '"666999"' Any ideas on how to get the correct string from the query? I've also tried using just an ExpressionWrapper with the output field but since it doesnt cast the type in the SQL the code breaks afterwards when trying to execute the search because it uses the jsonb field still. -
Obtaining values from a foreign key Python model
Let's say I have these models/classes: class User(models.Model): id = models.AutoField. . . group = models.ForeignKey( Group, . . . ) . . . class Group(models.Model): id = models.AutoField. . . name = models.CharField. . . . . . In a custom logging function called when there is a change being made, I do this: obj = # object/model being updated; in this case: User old_values = {} new_values = {} for i in range(len(form.changed_data)): vname = obj._meta.get_field(form.changed_data[i]).verbose_name old_values.update( { vname: form[form.changed_data[i]].initial } ) new_values.update( { vname: form.cleaned_data[form.changed_data[i]] } ) That leads to this output: old_values = {'Group': 2} new_values = {'Group': <Group: New Group Name>} Looks like form.initial uses the id while form.cleaned_data uses some kind of unsightly object name format. Neither are desired. I want the output to look like this: old_values = {'Group': 'Old Group Name'} new_values = {'Group': 'New Group Name'} How do I do this? I cannot explicitly import the model name and use it. User and Group are merely two of dozens of models that must be treated non-explicitly in this generic logging function. I've tried apps.get_model(), get_object_or_404(), and other methods, but nothing has been working for me so far. -

Django not recognized in virtual environment altough already installed when inside virtual environment
I've created a virtual environment in my PC(Windows). I've pushed the project to my git repository and now cloned it into my Mac. I activated the virtual environment, and tried running : python3 manage.py runserver This error is raised : ImportError: Couldn't import Django. Are you sure it's installed and available on your PYTHONPATH environment variable? Did you forget to activate a virtual environment? I understand that the message sent from above is defined inside the manage.py if an ImportError is raised. What I'm trying to understand is how to make the virtual environment to include the python packages inside my project. I will explain what I've tried doing below. AFTER cloning the project, I've changed line in my pyvenv.cfg ... include-system-site-packages = true //previously = false ... I'm not sure what I did wrong while setting up the virtual environment and installing the packages while being IN the virtual environment. -

The app is being deployed in a docker container on an azure app service: URLs.py path('primaryexams/', TemplateView.as_view(template_name='xxxDB/primaryexams.html'), name='primaryExams'), path('primaryexamsdata/', views.PrimaryExamsView.as_view(), name='primaryexam_data'), views.py class PrimaryExamsView(generics.ListAPIView): serializer_class = PrimaryExamSerializer template_name='xxxDB/primaryexams.html' def get_queryset(self): return xxxPrimaryExamData.objects.all() def filter_for_datatable(self, queryset): # filtering search_query = self.request.query_params.get('search[value]') if search_query: lookups = Q(xxxid__first_name__icontains=search_query)|Q(xxxid__last_name__icontains=search_query)|Q(xxxid__xx_id__icontains=search_query) queryset = xxxPrimaryExamData.objects.filter(lookups) return queryset def list(self, request, *args, **kwargs): draw = request.query_params.get('draw') queryset = self.filter_queryset(self.get_queryset()) recordsTotal = queryset.count() filtered_queryset = self.filter_for_datatable(queryset) try: start = int(request.query_params.get('start')) except (ValueError, TypeError): start = 0 try: length = int(request.query_params.get('length')) except (ValueError, TypeError): length = 25 end = length + start serializer = self.get_serializer(filtered_queryset[start:end], many=True) response = { 'draw': draw, 'recordsTotal': recordsTotal, 'recordsFiltered': filtered_queryset.count(), 'data': serializer.data, } return Response(response) serializers.py class PrimaryExamSerializer(serializers.ModelSerializer): xxx_id = serializers.ReadOnlyField(source='xxxid.xxx_id') last_name = serializers.ReadOnlyField(source='xxxid.last_name') first_name = serializers.ReadOnlyField(source='xxxid.first_name') program_institution = serializers.ReadOnlyField(source='program_institution.institution_id') program_institution_name = serializers.ReadOnlyField(source='program_institution.institution_name') test_center_institution = serializers.ReadOnlyField(source='test_center_institution.institution_id', default='none') class Meta: model = AbnsPrimaryExamData fields = ( 'id','xxx_id','last_name','first_name','medical_school','program_institution','program_institution_name','graduation_year','test_center_institution' ) When I try to load the data I get an ajax error, and when I look at the request its getting a 500 server error: https://xxxinternal.azurewebsites.net/xxxDB/primaryexamsdata/?draw=1&columns%5B0%5D%...blah...blahh I have other views set … -
add a menu at draw marker in Folium?
I just add a menu onche you clic on the draw maker in draw.py toolbar I modified the html of the map using this code {{ this._parent.get_name() }}.on('draw:drawstart', function(e){ var type = e.layerType, layer = e.layer; if (type === 'marker') { console.log('drawing starting... ' + e.layer) // Do marker specific actions var html = "<br><li class=''><a class='' title='Ubicacion de mujeres'>Ubicacion de mujeres</a></li><br>" + "<li class=''><a class='' title='Zona de Violencia'>Zona de Violencia</a></li><br>" + "<li class=''><a class='' title='Poblaciones diversas'>Poblaciones diversas</a></li><br>"; document.querySelector(".leaflet-draw-actions").innerHTML += html; } }); What i'm trying to do is to add a menu so the user can create a marker depending on what type of layer you choose previously my idea es in this image here When i do this, the "cancel operation" does not work anymore and also i dont know how to change the color of the marker draggable that it is displayed. Any idea will be so helpful Thank you and regards! -
Django yfinance historical data
I'm running a private Django project, that might be summarized as an html page with a form composed of an input search, and a submit button. I want to be able to write any stock ticker ('AAPL') in the input, and to generate a chart following the request. However, I made all my tests outside the django framework. Here comes the tricky part. My code related to the data scrapping designed previously, does not work when executed in the Django framework. from yahoo_finance import Share def checkview(request): yahoo = Share('YHOO') stock = yahoo.get_open() return HttpResponse(room) Here is the error code. enter image description here Also, I tried a different approach with this code: import yfinance as yf tsla = yf.Ticker("TSLA") hist = tsla.history(period='1y') import plotly.graph_objects as go fig = go.Figure(data=go.Scatter(x=hist.index,y=hist.Close, mode='lines')) fig.show() Can someone explain me, how can I solve the error ? And, how to install properly packages in the Django Framework. As an example, I will want to use Plotly going further in this project. Thanks !
