Django form widget - Add suffix while keeping the NumberInput
I have a form input on body height. I would like to put 'cm' after the height number (e.g. 183cm instead of just selecting 183) but keep it as a NumberInput. Is it possible to add the suffix in the widget? I have the following form.py: from django import forms from .models import Account class RegistrationForm(forms.ModelForm): body_height = forms.NumberInput(attrs={'min':120,'max':230,'step':1, 'required':False,}) class Meta: model = Account fields = ['body_height','otherfields'] def __init__(self, *args, **kwargs): self.fields['body_height'].widget.attrs['placeholder'] = 'Your height (centimeters)' -
How to assign default value of the model based on the value of ForeignKey
I have the Account model were I store information about preferred units. However I also want to allow user to change the units for particular exercise which by default should be Account.units. Here are my models: class Account(models.Model): """Model to store user's data and preferences.""" UNIT_CHOICES = [ ('metric', 'Metric'), ('imperial', 'Imperial') ] uuid = models.UUIDField(default=uuid.uuid4, unique=True, primary_key=True, editable=False) created = models.DateTimeField(auto_now_add=True) owner = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, null=True, blank=False) units = models.CharField(max_length=255, choices=UNIT_CHOICES, default=UNIT_CHOICES[0], null=False, blank=False) weight_metric = models.FloatField(null=True, blank=True) height_metric = models.FloatField(null=True, blank=True) weight_imperial = models.FloatField(null=True, blank=True) height_imperial = models.FloatField(null=True, blank=True) def __str__(self): return self.owner.email class CustomExercise(models.Model): UNIT_CHOICES = [ ('metric', 'Metric'), ('imperial', 'Imperial') ] uuid = models.UUIDField(default=uuid.uuid4, unique=True, primary_key=True, editable=False) created = models.DateTimeField(auto_now_add=True) owner = models.ForeignKey(Account, on_delete=models.CASCADE, null=False, blank=False) preferred_units = models.CharField(max_length=255, choices=UNIT_CHOICES, default=owner.units, null=False, blank=False) # <- throws an error that "ForeignKey doesn't have units attribute." name = models.CharField(max_length=255, null=False, blank=False) measure_time = models.BooleanField(default=False) measure_distance = models.BooleanField(default=False) measure_weight = models.BooleanField(default=False) measure_reps = models.BooleanField(default=False) def __str__(self): return f'{self.owner}:{self.name}' As posted in code sample I tried to get that default value from ForeignKey, which not unexpectedly did not work out. So my question is: what is the correct solution to implement this kind of feature? -
VsCode not Auto-importing Django depenencies
I'm learning Django and working with VsCode. In PyCharm, the imports are working fine. PyCharm importing However in VsCode: VsCode importing Is VsCode just not capable of this? Or is there something iffy with my configuration? I have the correct Python interpreter configured as well. I have Pylance installed and it suggests imports automatically for some other things, rather unhelpfully usually. e.g., VsCode importing unhelpful I have tried settings some options in settings.json. The python.analysis.extraPaths adding the path to django on the Python installation. I have tried python.analysis.indexing set to true as well. I haven't found any other solutions. -
Django APIView: how to display calculated value
I have to display a calculated value in APIVIEW, but I can't figure out how to set up the view, it's giving me an error. The code, that returns a simple JSON is working fine: def protein_coverage(request, protein_id): try: proteins = Protein.objects.filter(protein=protein_id) domain_length = 0 coverage = domain_length / protein_length except Protein.DoesNotExist: return HttpResponse({'message': 'This Protein does not exist'}, status=status.HTTP_404_NOT_FOUND) if request.method == 'GET': serializer = ProteinCoverageSerializer(coverage) return JsonResponse(serializer.data,safe=False) I tried this for the APIView: class ProteinCoverage(generics.RetrieveAPIView): serializer_class = ProteinCoverageSerializer def get_queryset(self): pk = self.kwargs['protein_id'] proteins = Protein.objects.filter(protein=pk) domain_length = 0 coverage = domain_length / protein_length return coverage But it's giving me an error: Expected view ProteinCoverage to be called with a URL keyword argument named "pk". Fix your URL conf, or set the `.lookup_field` attribute on the view correctly. I'm not sure, which API is suitable for this situation and how to pass a single variable to it. I also checked the documentation, but it's not clear. How do I convert this JsonResponse to APIView? -

Create multiple model instances upon creation of another model
What I am trying to achieve is the following: The user searches for a keyword in a form. The search query is saved in a model called TweetSearch. When the search is submitted a function get_tweets() will be run which scrapes tweets with the keyword that the user submitted. These tweets must be saved in a model called TweetInstance. Then some data from TweetInstance is shown in a dashboard. I don't know how to create instances of multiple models in one view, so I added a view in between the searchform and the dashboard that runs the function get_tweets() and adds them to the database. This does not work well and there must be a better way to do this. Can anyone help me? I tried the following: models.py: class TweetSearch(models.Model): from datetime import datetime, timedelta search_term = models.CharField(max_length=200, blank=True) QUERY_CHOICES = ( ('t', 'in tweet'), ('h', 'in hashtag'), ('u', 'username'), ) id = models.UUIDField(primary_key=True, default=uuid.uuid4) query_type = models.CharField(max_length=1, choices=QUERY_CHOICES, blank=True, default='t') start_default = datetime.now() - timedelta(days=30) start_date = models.DateTimeField(default=start_default) end_date = models.DateTimeField(default=datetime.now) language = models.CharField(max_length=200, blank=True, null=True) country = models.CharField(max_length=200, blank=True, null=True) city = models.CharField(max_length=200, blank=True, null=True) searcher = models.ForeignKey(User, on_delete=models.SET_NULL, null=True, blank=True) created = models.DateTimeField(auto_now_add=True, null=True) def __str__(self): … -

Django - Storing user info sessions vs database
In my django website I have a login system which uses sessions to keep the user logged in across all pages. I would like to store recently viewed items for users if they are logged in or browsing as a guest user. When a user is logged in I would like the user to see their recently viewed items even when they access my website on another device. I understand that if a user is browsing as a guest recently viewed items would be stored locally in the browser. Would i need to store recently viewed items in a database so that it can be accessed and displayed on other devices. Or is there a way to achieve this with the use of sessions. example of request.session dict { "user_id":-1, # (-1), flag value when no user is logged in (browsing as guest) "recently-viewed":['sw0001a','sw0036a',...], "login_attempts":2, } -

I'm using the django rest framework to create an API. models.py class DepartmentModel(models.Model): DeptID = models.AutoField(primary_key=True) DeptName = models.CharField(max_length=100) def __str__(self): return self.DeptName class Meta: verbose_name = 'Department Table' class EmployeeModel(models.Model): Level_Types = ( ('Genin', 'Genin'), ('Chunin', 'Chunin'), ('Jonin', 'Jonin'), ) EmpID = models.AutoField(primary_key=True) EmpName = models.CharField(max_length=100) Email = models.CharField(max_length=100,null=True) EmpLevel = models.CharField(max_length=20, default="Genin", choices=Level_Types) EmpPosition = models.ForeignKey(DepartmentModel, null=True, on_delete=models.SET_NULL) class Meta: verbose_name = 'EmployeeTable' # Easy readable tablename - verbose_name def __str__(self): return self.EmpName serializer.py from appemployee.models import EmployeeModel,DepartmentModel class EmployeeSerialize(serializers.ModelSerializer): class Meta: model = EmployeeModel fields = '__all__' class EmployeeSerializer(serializers.ModelSerializer): emp_dept = serializers.CharField(source='DepartmentModel.DeptName') class Meta: model = EmployeeModel fields = ('EmpID','EmpName','Email','EmpLevel','emp_dept') views.py class EmployeeTable(APIView): def get(self,request): try: emp_obj = EmployeeModel.objects.all() empserializer = EmployeeSerialize(emp_obj,many=True) except Exception as err: return Response(err) return Response(empserializer.data) this would provide me with: [ { "EmpID": 1, "EmpName": "Hashirama Senju", "Email": "hashirama.senju@konaha.com", "EmpLevel": "Jonin", "EmpPosition": 1 }, { "EmpID": 2, "EmpName": "Tobirama Senju", "Email": "tobirama.senju@konaha.com", "EmpLevel": "Jonin", "EmpPosition": 2 }, { "EmpID": 3, "EmpName": "Hiruzen Sarutobi", "Email": "hiruzen.sarutobi@konaha.com", "EmpLevel": "Jonin", "EmpPosition": 5 } ] what i really want is [ { "EmpID": 1, "EmpName": "Hashirama Senju", "Email": "hashirama.senju@konaha.com", "EmpLevel": "Jonin", "DeptName": "Hokage" }, { "EmpID": 2, "EmpName": "Tobirama Senju", "Email": "tobirama.senju@konaha.com", "EmpLevel": "Jonin", "DeptName": "Hokage" … -
any docs abot django + htmx for JSON
I found many reference (docs and video) about how to use htmx in django for doing parent-child crud UI. Is there any docs or excample on how to do 'dynamicaly added form field' with just single model class? My case is to make an app that take care of business mailing templates. models.py class MailTemplate(models.Model): code = models.CharField(verbose_name='Code',max_length=10, unique=True) name = models.CharField(verbose_name='Name', max_length=30) docx = models.FileField(verbose_name='docx File') dataschema = models.TextField(null=True, blank=True) class Mail(models.Model): mailtemplate = models.ForeignKey(MailTemplate, on_delete=models.SET_NULL) created = models.DateTimeField(auto_now_add=True) edited = models.DateTimeField(auto_now=True) data = models.TextField(null=True, blank=True) What I want is a form to add/edit record of 'MailTemplate'. that form will 'look like' 'stacked inline' but the 'child' is from parsing MailTemplate.dataschema. Example of MailTemplate.dataschema : [ { "name": "to", "label": "To", "type": "string", }, { "name": "platenumber", "label": "Plate Number", "type": "string", }, ] I really appreciate any help.
