How to add empty_label with smart-selects ChainedForeignKey in Django
I have the following models: class CompanyRole(models.Model): name = models.CharField(max_length=150) def __str__(self): return self.name class Office(models.Model): company_role = models.ForeignKey(CompanyRole, on_delete=models.SET_NULL, null=True) name = models.CharField(max_length=150) def __str__(self): return self.name class User(AbstractBaseUser, PermissionsMixin): email = models.EmailField(_('email address'), unique=True) username = models.CharField(max_length=150, unique=True) company_role = models.ForeignKey(CompanyRole, on_delete=models.SET_NULL, null=True) office = ChainedForeignKey( Office, on_delete=models.SET_NULL, null=True, blank=True, chained_field="company_role", chained_model_field="company_role", show_all=False, auto_choose=True, sort=True, ) objects = CustomAccountManager() USERNAME_FIELD = 'email' REQUIRED_FIELDS = ['username'] def __str__(self): return self.username And the following form: class RegisterForm(UserCreationForm): office = forms.ModelChoiceField(queryset=Office.objects, empty_label='Select Office') def __init__(self, *args, **kwargs): super(RegisterForm, self).__init__(*args, **kwargs) self.fields['email'].widget.attrs.pop("autofocus", None) class Meta: model = User fields = ["username", "email", "company_role", "office"] This was all working fine with the chained selects from smart-selects app, however I needed to show the empty_label to show 'Select Office' which I managed to do by adding the following line to my form as shown above: office = forms.ModelChoiceField(queryset=Office.objects, empty_label='Select Office') But since adding that line to my form the empty_label now shows but the chained selection is broken as in previously the user would select company role and depending on selection would populate the list of offices. For example: company role selection was translator then no offices would be populated but if they selected … -
JQuery UI Autocomplete for Django
The project I'm currently working on requires that a form field have autocomplete functionality. The data to be populated in the autocomplete list is pulled each time the page is loaded using an API call to a 3rd-party platform. Is it possible to call a Django views function (that will implement the above mentioned API call) to provide the JQuery-UI source with the list for auto-completion? According to the documentation (https://api.jqueryui.com/autocomplete/#option-source), the source function type might be the best option for my scenario, but I might be mistaken. So I'm open to a better way of doing it in JQuery-UI if possible. thanks. -
How "--keepdb" affects setUpTestData?
From the Django documentation I see that a Django TestCase wraps the tests within two nested atomic() blocks: one for the whole class and one for each test. Then I see that setUpTestData method "allows the creation of initial data at the class level, once for the whole TestCase": so we're talking about the whole class atomic block. This means that the --keepdb flag should not affect this behaviour, because what this flag do is just skip the database create/destroy. But I noticed that if I run the test with the --keepdb flag the data I create in the setUpTestData method are preserved. I'm fine with this but I want to understand what --keepdb exactly does, because I can't understand why this happens. I tried to look directly at the Django TestCase class source code but I don't see any check about the --keepdb option. Why - if I run my test with the --keepdb option - the data I create in setUpTestData method are preserved? -
Heroku Python Local Environment Variables
Working on a heroku django project. Goal: I want to run the server locally with same code on cloud too (makes sense). Problem: Environments differ from a linux server (heroku) to a local PC windows system. Local environment variables differ from cloud Heroku config vars. Heroku config vars can be setup easily using the CLI heroku config:set TIMES=2. While setting up local env vars is a total mess. I tried the following in cmd: py -c "import os;os.environ['Times']=2" # To set an env var then py -c "import os;os.environ.get('Times','Not Found')" stdout: "Not Found". After a bit of research it appeared to be that such env vars are stored temporarily per process/session usage. So I came up with the idea of using .env file. I would like os.environ to be redirected to .env file of the root heroku project instead of the PC env vars. So I found this perfect tool direnv perfect solution for Unix-like OSs but not for Windows. views.py code (runs perfect on cloud, sick on the local machine): import os import requests from django.shortcuts import render from django.http import HttpResponse from .models import Greeting def index(request): # get method takes 2 parameters (env_var_string,return value if var is … -
Getting sum of averages in a django queryset
def get_queryset(self): current_academic_year = get_current_academic_year() domains = Domain.objects.all() start_date = self.request.query_params.get("start_date", current_academic_year.start_date) end_date = self.request.query_params.get("end_date", current_academic_year.end_date) queryset = Account.objects.annotate(**{ f"domain_overall_{domain.uuid}": Avg( "assessed_from__accountevaluationresult__calculated_rating", filter=Q( assessed_from__updated__range=(start_date, end_date) ) & Q(assessed_from__domain=domain) ) for domain in domains }).annotate(**{f"domains_total": ~query~ }) There are five domains. Here I got 5 key-value pairs with certain calculated values for each domain. I need to get the sum of those values from the first annotation, but have no idea how to retrieve it in continuous annotations.

The SECRET_KEY setting must not be empty. Django docker
i tried to find solution on stack and other websites but without result. Im fighting with django for some days. I got my django app dockerized and it works fine. I'm using .env file to serve secret variables. And here start the problem. I can't use travis CI or debug mode in Visual Studio Code becouse my env variables are not visible. When im trying to run travis or debuger, im getting error "The SECRET_KEY setting must not be empty". The question is, how to properly configure my django app or docker instance to use env variables in every situation? Some days ago i tried to write secret_key without hidding it, but my debuger is failing on connection with database, so it seems that my variables are not visible at all. But as i said, when i run my app in normal mode or as a docker instance it works fine, my .env file is visible for django. Here you can find my settings.py SECRET_KEY = os.getenv('SEC_KEY') DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql', 'NAME': os.getenv('DB_NAME'), 'USER': os.getenv('DB_USER'), 'PASSWORD': os.getenv('DB_PASSWORD'), 'HOST': os.getenv('DB_HOST'), 'PORT': 5432 } } And here is my docker-compose file: version: '3.4' services: electronicshop: image: electronicshop build: context: … -

End a for loop if a certain condition is met in Django using templates
A similar question was asked before but the provided solutions did not work for me. Let's say I receive a list from the django views, for instance: context['requests'] = requests In the template: {% for r in requests %} {% if r.status == "Active" %} //do A {% else %} //do B {% endif %} {% endfor %} The requests list has 10 elements, one of them satisfies the condition of r.status == "Active". (invented example) What I want is: Check the requests list to determine if any of the elements in the list satisfies the condition of r.status == "Active" (or whatever condition, this is just an example) If some element in the list has the status Active the for loop will execute only one iteration, run the //do A code and then the loop will finish/break. If no element in the list has the status Active, the for loop will execute the //do B once and then break. I'm a bit confused and I don't know if there is another default tag to do this type of operation in Django -

How to youtube-dl video download directly to a user side not download file in local system using python Django?

My App's view.py code snippet: def postQuestion(request): print ("---------------reposting-----------------") dataOwners=db.dataOwners if request.method=="POST": json_dict={} json_dict['User_ID']=request.user.id json_dict['Question_asked']=request.POST['question'] json_dict['Category']=request.POST['cat'] json_dict['Sub-Category']=request.POST['subCat'] moderator_document = dataOwners.find({'Category' : json_dict['Category']}) mods_list=[] for i in moderator_document: mods_list.append(i['Moderator']) json_dict['Moderators_available']=mods_list json_dict['Moderator_assigned']='null' json_dict['Status']="Pending Assignment" json_dict['Answer_given']= 'null' if 'revision' in request.POST and 'qid' in request.POST: json_dict['Comments']="Query details corrected" questionColl.find_one_and_update({"_id" : ObjectId(request.POST['qid'])}, {"$set": {"Question_asked":json_dict['Question_asked'],"Category":json_dict['Category'] ,"Sub-Category":json_dict['Sub-Category'],"Moderators_available":mods_list,"Comments":json_dict['Comments'],"Status":json_dict['Status'] } },upsert=True) else: json_dict['Comments']=request.POST['comments'] questionColl.insert_one(json_dict) data=json.loads(json_util.dumps(json_dict)) return HttpResponse(data) I idea is that when someone post a question from the html front-end, the control goes to the above function which then puts the question details in a database collection (local mongodb). The data is being collected through a ajax call which should push the question details to "postQuestion" view. However I am getting an error like below: [28/Dec/2021 15:20:27] "POST /%7B%%20url%20%22postQuestion%22%20%%7D HTTP/1.1" 404 5624 Not Found: /{% url "postQuestion" %} My ajax call snippet: // Post a question ajax call // $(document).ready(function(event){ $(document).on("click","#postQuestion",function(event){ event.preventDefault(); //data to … -
This field is required DRF on server side only
I created a django restframe work api which is working fine locally. But when I moved it to the server, it stop working. On server i am getting this { "file_name": [ "This field is required." ] } Here is the code view.py class VideoUploadViews(APIView): def post(self, request): serializer=VideoUploadSerializer(data=request.data)#acess the data if serializer.is_valid():#check validation start=time() vid_path=serializer.data["file_name"] vid_path=os.path.join(settings.S3PATH,vid_path) pred_hr=inference.predicthr(vid_path) end=time() return Response({"status": "success", "predicted hr": pred_hr,'time taken':end-start},\ status=status.HTTP_200_OK) else: return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) models.py class VideoUploadModel(models.Model): file_name = models.CharField(max_length=100,blank=False, null=False) serializer.py class VideoUploadSerializer(serializers.ModelSerializer): class Meta: model=VideoUploadModel fields='__all__'
