Django modelform widget attributes replaced or disregarded
I've been scratching my head over this for the last little while. I have been able to change the modelfield's field queryset and widget attributes, well somewhat! class InvoiceItemForm(ModelForm): UOM = forms.ChoiceField (choices = site_defaults.UOM) class meta: model = InvoiceItem fields = ['name', 'costcode', 'rate', 'quantity',] labels = {'name': 'Item', 'rate': 'Cost Per Unit', 'quantity': 'Base Quantity'} widgets = {'UOM': forms.Select(choices = site_defaults.UOM )} def __init__(self, current_user, current_project, *args, **kwargs): ''' Rendering custom ModelForm ''' super(InvoiceItemForm, self).__init__(*args, **kwargs) the_title = None the_instance = kwargs.get('instance', None) if the_instance: the_costcode = the_instance.costcode if the_costcode: the_title = the_costcode.title self.fields['costcode'].queryset = CostCode.objects.filter(project = current_project, item = 0) self.fields['costcode'].widget = forms.TextInput(attrs={'class': 'site-flex-select-large', 'value': the_title}) When this is rendered, the costcode field takes the right instance. Also, the class is shown as site-flex-select-large, but the title is shown as the instance.id and not the_title which is the instance.title (a text field is displayed with value of 192 instead of the title of the invoice item). Why is Django ignoring some changes and accepting some other changes to the field? I'm not sure if it is a relevant detail or not, but the modelform is used in an inlineformset: expenses_forms = self.InvoiceItem_InlineFormSet(instance = the_invoice, prefix='expenses', form_kwargs={'current_user': user, … -
Reverse for 'patient_update' with keyword arguments '{'pk': ''}' not found. 1 pattern(s) tried: ['patients/update/(?P<pk>[0-9]+)$']?
I made a view where users can edit the patients information and as I'm using a custom user model I had to make a custom update/delete view.The views are working when i enter them manually by the url but when i put a link reference to them by an anchor tag i get an error that it can't access the pk,I tried following many answers here and vids on YT but the error is still there Views.py def PatientUpdateView(request,pk=None): patient = get_object_or_404(models.Patient, pk=pk) form = forms.PatientForm(request.POST or None ,instance=patient) if form.is_valid() : patient = form.save(commit=False) patient.save() messages.success(request,"patient updated!") context = { 'patient': patient, 'form': form } return render(request,'patients/patient_edit_form_success.html',context) else: context = { 'patient' : patient, 'form': form, } return render(request, 'patients/patient_edit_form.html', context) and here's how i call it in an anchor tag <a class="btn btn-info btn-sm" href="{% url 'patients:patient_update' patient.pk %}">Open</a> I tried pk = patient.pk pk = pk and many other ways of calling it. -
How do you use downloaded templates in Django
I have found these really cool templates online and I would like to use them for building my website. Is there any way of not copying the links for bootstrapping but for me to use the templates downloaded and tweak them? I have looked online and all they suggested was bootstrapping. -
Django - How to serialize inheritance
I walked through the documentation at https://django-model-utils.readthedocs.io/en/latest/managers.html to learn more about the InheritanceManager.I won't add the models.py because it is the same as in the documentation. So, here is my views.py: class PlaceList(generics.ListAPIView): serializer_class = PlaceSerializer def get_queryset(self): return Place.objects.select_subclasses() As you can see, the line return Place.objects.select_subclasses() returns all the Bar, Restaurant or Place instance stored in the database. My serializers.py looks like the following: from rest_framework import serializers from genericRelations.models import Place, Restaurant, Bar class PlaceSerializer(serializers.ModelSerializer): class Meta: model = Restaurant fields = ('id', 'location') class RestaurantSerializer(serializers.ModelSerializer): class Meta: model = Restaurant fields = ('id', 'location', 'restaurant_name') class BarSerializer(serializers.ModelSerializer): class Meta: model = Bar fields = ('id', 'location', 'bar_name') I do not know how to modify the PlaceSerializer so that it also serializes/deserializes the subclasses of Place. E.g. something like 'if a Bar instance is encountered, then use the BarSerializer' and 'if a Restaurant instance is encountered, then use the RestaurantSerializer'. Note: When the URL is .../places/ then PlaceList is performed which results in this output: { "places": [ { "id": 1, "location": "Köln" }, { "id": 2, "location": "Köln" }, { "id": 3, "location": "Köln" }, { "id": 4, "location": "Köln" }, { "id": 5, "location": "Köln" … -

How do I validate a field based on it's initial value in forms.py?
I have a custom self.clean method in forms.py which contains a check on whether the POSTed date values overlap with existing records. In the case where the user edits their record, but does not change the dates, this validation stops the record update. How can I change the validation with If statement or otherwise dependant on if the user has modified the start_date or end_date fields? I've tried looking at things like self.get_initial() and self.has_changed() which seem to only be applicable in the view function? I'd rather validate in forms.py. If I could filter out the record currently being edited from my "overlap" validations, that may be the neatest solution. forms.py: class EditBookingForm(ModelForm): class Meta: model = Bookings #user not included as that is handled in views fields = ['start_date', 'end_date', 'type', 'approved', 'members', 'guests'] ... def clean(self): form_data = self.cleaned_data #check if dates overlap by more than one day (ie. can start/end on the same day) overlap_in = Bookings.objects.filter(start_date__lt=form_data['start_date'], end_date__gt=form_data['end_date']).count() overlap_st = Bookings.objects.filter(start_date__lt=form_data['start_date'], end_date__gt=form_data['start_date']).count() overlap_end = Bookings.objects.filter(start_date__lt=form_data['end_date'], end_date__gt=form_data['end_date']).count() overlap_same = Bookings.objects.filter(start_date=form_data['start_date'], end_date=form_data['end_date']).count() overlap_over = Bookings.objects.filter(end_date__gt=form_data['start_date'], start_date__lt=form_data['end_date']).count() overlap = overlap_end + overlap_in + overlap_same + overlap_st + overlap_over if overlap > 0: self._errors["start_date"] = ["Your dates overlap with an existing … -

I have a field: forms.CheckboxSelectMultiple(). How can I access it's options in JS?
I'm setting up a form, which has a field = forms.CheckboxSelectMultiple() The field is a ManyToMany field of a model. It'll display the options that the model has to relate to the other fields. models.py class Tag(models.Model): name = models.CharField(max_length=30, unique=True) def __str__(self): return self.name class Entry(models.Model): # ...other fields tags = models.ManyToManyField(Tag, related_name='entries', blank=True) #other fields... And the form: class NewEntryForm(forms.ModelForm): # ...other code 'tags': forms.CheckboxSelectMultiple(attrs={ 'class': 'form_new_entry_tags', 'id': '' }), I want to access the text of the options (the options would be all the tags available), in JS, so as to display it on another place when the checkbox is checked. The text is not the input's value, as one might think it'd be. It is html that comes directly from the django form, which seems to not have a selector. I'm trying to do this: let display_when_checked = document.querySelector("#display") let checkbox = document.querySelector("#checkbox") checkbox.addEventListener('change', function() { if (this.checked) { display_when_checked.innerHTML = checkbox_value } } But I can't access checkbox_value. And the HTML is: <ul> <li> <label> <input type="checkbox" value="1" class="form_new_entry_tags"> "text of the option" <--- I want to access this. </label> </li> </ul> When I hover with the dev tools in the browser, the selector for … -
Request attributes
I have a page, and there are 3 types of button(apple,banana, orange), by clicking the first button, a form comes up to get information. The first button should send information to the apple Model, the banana button should send information to the banana Model and so orange! here is my models.py: from django.db import models class Apple(models.Model): first_name = models.CharField(max_length=100) class Banana(models.Model): first_name = models.CharField(max_length=100) class Orange(models.Model): first_name = models.CharField(max_length=100) my forms.py: from django import forms class Fruit(forms.Form): first_name = forms.CharField(max_length=100) my views.py: def fruitForm(request): form = Fruit() if request.method == 'POST' & request.id == 'apple': form = Fruit(request.POST) if form.is_valid(): Apple.objects.create(**form.cleaned_data) elif request.method =='POST' & request.id =='orange': form = Fruit(request.POST) if form.is_valid(): Orange.objects.create(**form.cleaned_data) elif request.method =='POST' & request.id =='banana': form = Fruit(request.POST) if form.is_valid(): Banana.objects.create(**form.cleaned_data) return render(request, 'main/home.html', {'form':form}) my home.html: <button class='btn btn-primary' data-target='#orange'> Add </button> <form action=# method="POST" id = "orange"> {% csrf_token %} {{ form.as_p }} </form> well, when I try go to main page (where the buttons are), I got this error: 'WSGIRequest' object has no attribute 'id' request doesn't have the id attribute, right?

Django model CreateView does not render form fields in HTML
I am trying to setup a class based 'CreateView' for a model in my django site, but when the create html page renders, the model fields are not rendered. Only the submit button shows up on the web page. However, when debugging, I overrided the 'form_invalid' method in the class view, and the form object had the required HTML for all fields stored in the object. If I take this HTML and manually add it to the HTML of the create page in the browser I can fill out the fields and post the data to the database. At this point I have not found an obvious answer as to why the form fields are not rendered so any help on this would be greatly appreciated. environment used: python 3.7.3, django 2.2.3 models.py: class Alert(models.Model): RAIN = 'Rain' SNOW = 'Snow' COLD = 'Cold' HEAT = 'Heat' WEATHER_CHOICES = [ (RAIN, 'Rain'), (SNOW, 'Snow'), (COLD, 'Cold'), (HEAT, 'Heat'), ] DAILY = 'Daily' WEEKLY = 'Weekly' INTERVAL_CHOICES = [ (DAILY, 'Daily'), (WEEKLY, 'Weekly'), ] weather_type = models.CharField(max_length=15, choices=WEATHER_CHOICES, default=RAIN) interval = models.CharField(max_length=10, choices=INTERVAL_CHOICES, default=DAILY) search_length = models.IntegerField(default=1) user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) active = models.BooleanField(default=False) views.py: class CreateAlertView(LoginRequiredMixin, CreateView): template_name = 'users/alert_form.html' … -

Django Rest Framework, Registering viewset with router breaks everything - circular import, "Module" object is not iterable
Currently trying to configure my project to work with a router as I plan on using multiple viewsets, all the components seem to work individually, specifying the path manually produces no errors and works as intended. However once i attempt to register my viewset with the router it all explodes Have compared what I've done to the tutorial on the Django Rest Framework site and everything seems to be done correctly.
