Django Tabularinline with Auto complete field
I am trying to implement an auto complete field in a tabular inline model.where a user selects a site and the address cell is consequently filled with the appropriate address I defined my fields in a form as below : self.fields['sites'].widget = forms.Select( attrs={ 'id': 'id_sites', 'onchange': 'getsiteaddress(this.value)', 'style': 'width:200px' }, choices=sites_list, ) self.fields['site_address'].widget = forms.TextInput( attrs={ 'id': 'id_siteaddress', 'style': 'width:200px' } ) Everything works fine for the first row My issue is that when I move to the second row of the inline model and select an address the cell of the first row is the one that changes. How can I call the second row? This is my jquery function function getsiteaddress(site){ let $ = django.jQuery; $.get('/Delivery/deploymentsite/'+ site, function(resp){ $('#id_siteaddress).val(resp.data) }); } I would really appreciate any help -
How do you set up a subprocess to receive api requests in Heroku?
I have a react frontend deployed to a web process on Heroku. I have a django backend that is deployed to an app process as shown below. I keep getting a 502 error, so I originally thought my issue was in django. However, after a mistake where I had the react open already, and changed the web process to be django, I had a fully functioning app. However, after a little bit of clicking around, I only got the backend. Long story short, I need a way for my backend to receive api request calls from my frontend. Nothing I have done seems to have worked. Having two web processes doesn't work because Heroku only takes the last one and basically ignores the other one. As it stands, I am using http requests as the api call, but realistically, I just need a way to communicate between Django and React. If I have to redo something, I am willing to do so. Procfile release: python manage.py migrate backend api: gunicorn backend.wsgi:application web: bin/boot To be clear, web: bin/boot is a buildpack specifically for react apps. It works just fine, and I do not believe it is the issue. -
Djanog - Is there a better approach for a DRY CRUD solution in views.py?
I'm fairly new to Django, and I am trying to understand a better way to implement CRUD in my views.py file. Example view.py: # Assume I have two generic models: Foo and Bar from django.views.generic import UpdateView, DeleteView from .forms import FooForm, BarForm from .models import Foo, Bar class FooUpdateView(UpdateView): model = Foo form_class = FooForm template_name = 'foo_form.html' success_url = reverse_lazy('success-page') class BarUpdateView(UpdateView): model = Bar form_class = BarForm template_name = 'Bar_form.html' success_url = reverse_lazy('success-page') class FooDeleteView(DeleteView): model = Foo template_name = 'foo_delete.html' success_url = reverse_lazy('success-page') class BarDeleteView(DeleteView): model = Bar template_name = 'Bar_delete.html' success_url = reverse_lazy('success-page') Is there a way like the example below, where I can create a base class that I can inherit from, but still allows me to override and customize functions and variables. class UpdateBaseView(UpdateView): form_class = self.model_form template_name = 'self.model_form.html' success_url = reverse_lazy(success_url) class FooUpdateView(UpdateBaseView): model = Foo class BarUpdateView(UpdateBaseView): model = Bar success_url = reverse_lazy('bar-success') -
Django Models: How to write query for multiple value with filtering multiple value
I have user local_user and personal models. I try to make a query with the multiple results but should filtered with multiple value. Models have one to one relations between each other. There are models. class Hospital_Local_User(models.Model): id = models.AutoField(primary_key=True) email = models.CharField(max_length=45) password = models.CharField(max_length=45) phone = models.CharField(max_length=45) class Personal (models.Model): id = models.AutoField(primary_key=True) name = models.CharField(max_length=255) lastname = models.CharField(max_length=255) user_roles_id = models.ForeignKey(User_Role, on_delete=models.CASCADE) hospitals_id = models.ForeignKey(Hospital, on_delete=models.CASCADE) hospital_local_users_id = models.OneToOneField( Hospital_Local_User, on_delete=models.CASCADE) and This is the code I try to build. def listDoctors(request): userRole = User_Role.objects.get(id=2) Doctors = Personal.objects.filter(user_roles_id=userRole) hospLocUser = Hospital_Local_User.objects.filter(id=Doctors) serialized_queryset = serializers.serialize('json', hospLocUser) return JsonResponse(json.loads(serialized_queryset), safe=False) I try to make two objects then merge them into one object because when I try to convert Personal model to json it does not show email and phone fields. It just shows them as local_user_id. I do not need local user id I need fields in it. -
Pytest and mixer does not raise errors when testing non model fields
I am following Test driven development and am working through Django models with mixer, Pytest and pytest-django. This is the test for the Project model: class TestProject: def test_model_valid_fields(self, django_user_model): project = mixer.blend( 'workspaces.Project', title="Road map", non_model_field="some value" ) assert project.pk == 1 assert project.title == "Road map" assert project.non_model_field == "some value" The Project model, notice that Project model has only the title field: class Project(models.Model): title = models.CharField(max_length=200) Two things: How is mixer allowing the use of non model fields? Why is Pytest not raising an error, since the Project model does not have non_model_field field? What am I missing here? -

Running django view/function on button click
I have the following button: <a class="btn btn-success">Accept</a>. Like this previous stack overflow question, I want to call my view after the button is clicked, but I can not seem to get it to work. What I have tried: Using AJAX, treating button like a form, requesting post data, but this does not seem to work. How can I make it so when my button is clicked, I call the bellow view? def acceptdonation(request, pk): Donation.objects.filter(pk=pk).update(views=F('views')+1) return HttpResponseRedirect(request.GET.get('next'))) -

django forms .clean method is not getting invoked
Django forms clean method not getting invoked, I read django's full clean doc and other relevant stackoverflow questions. but could not get the answer at all.

Django: right-align output in admin listview

Django overriding the save method gives error
Disclaimer, I'm still new to a lot of concepts in Django so patiance please. So what I'm trying to do is the value of name from Counter model, assign it to the value of code from Order model.

How to cache a dictionary in Django?
I am using Django as my Webframework. I have a method that takes really long ~10 sec to complete. It returns a Dictionary which I then display in the templates. This method is called on a POST request after a button click. When the user reloads the page the View gets a GET request and all the results from before dont get displayed anymore. How can I somehow cache the Dictionary so I can even display it on a get request when the user once did the POST request? -

(python) Github Actions test selenium copy paste
I am testing my python application with e2e tests and use github actions as part of my CI. Normal selenium tests work totally fine. I added a click to copy functionality and want to test it via a unit test. So far I am using pyperclip to do this: import pyperclip link = pyperclip.paste() assert link == "target link" Locally on my machine (OSX) everything works fine. Unfortunately, I am not able to get this library working with ubuntu on github actions. I get this error: Pyperclip could not find a copy/paste mechanism for your system. Please see https://pyperclip.readthedocs.io/en/latest/introduction.html#not-implemented-error for how to fix this. I've checked the page but I am not able to get it working. Does someone know a way how to access the clipboard in github actions?
