ModelForm has no model class specified. Django
I want to create a patient creating form for my system with Django but it is not working and I am getting an error: ValueError at /create/ ModelForm has no model class specified. I cannot understand that. I looked for similar question and I apply some solutions but it did not work. Where is my mistake? Can you help me? Thanks a lot for your attention. views.py def patient_create(request): if not request.user.is_authenticated: return Http404() form = PatientForm(request.POST or None, request.FILES or None) if form.is_valid(): post = form.save(commit=False) post.user = request.user post.save() messages.success(request, "Başarılı bir şekilde oluşturdunuz.", extra_tags='mesaj-basarili') return HttpResponseRedirect(post.get_absolute_url()) context = { 'form': form } return render(request, "template/patient_form.html", context) models.py class newPatients(models.Model): title = models.CharField(max_length=100) first_name = models.CharField(max_length=50) last_name = models.CharField(max_length=50) created_date = models.DateTimeField(default=timezone.now) dept = models.TextField() address = models.TextField() phone = models.CharField(max_length=15) notes = RichTextField(verbose_name="notes") def publish(self): self.published_date = timezone.now() self.save() def __str__(self): return self.title def get_create_url(self): return reverse('post:create', kwargs={'slug': self.slug}) def get_unique_slug(self): slug = slugify(self.title.replace('ı', 'i')) unique_slug = slug counter = 1 while newPatients.objects.filter(slug=unique_slug).exists(): unique_slug = '{}-{}'.format(slug, counter) counter += 1 return unique_slug def save(self, *args, **kwargs): self.slug = self.get_unique_slug() return super(newPatients, self).save(*args, **kwargs) class Meta: ordering = ['-created_date'] forms.py from django.forms import ModelForm from patients.models import newPatients … -
gunicorn failing to start supervisor: Django AWS EC2
I am watching this tutorial to deploy a django app on AWS EC2. https://www.youtube.com/watch?v=BzdYa9Lqlm4&list=PLDu5PyoUISmc1PdrUNUdc9LohmLA_Q-S5&index=2 For some reason I am unable to get the status of gunicorn to work properly. After creating an instance of EC2 on AWS. I have updated, upgraded everything, installed python, django, nginx,gunicorn and supervisor correctly. I created the folder and accessed it cd /etc/supervisor/conf.d/ Then I created the file sudo touch gunicorn.conf using NANO CONFIG file directory=/home/ubuntu/aws_demo command=/home/ubuntu/env/bin/gunicorn - - workers 3 - - bind unix:/home/ubuntu/aws_demo/app.sock aws_demo.wsgi:application autostart=true autorestart=true stderr_logfile=/var/log/gunicorn/gunicorn.err.log stdout_logfile=/var/log/gunicorn/gunicorn.out.log [group:guni] programs:gunicorn steps after creating the config file sudo mkdir /var/log/gunicorn sudo supervisorctl reread start gunicorn: sudo supervisorctl update (add process group) check gunicorn status: sudo supervisorctl status at this point: terminal response guni:gunicorn FATAL Exited too quickly (process log may have details) The structure of my entire project look like this aws_demo (Main folder) aws_demo (projectname) core (application name) I am not sure whats wrong but I feel like app.sock is not created because I cannot find it anywhere when I look for it manually on Ubuntu. Any feedback would be much appreciated. -
How to set model field default the same as OneToOneField attribute value?
There are Lecture and Task models. Every lecture has a topic. And every task has a topic and a lecture. class Lecture(models.Model): topic = models.CharField(max_length=30, blank=False) class Task(models.Model): lecture = models.OneToOneField(Lecture, on_delete=models.CASCADE) topic = models.CharField( max_length=30, blank=False, ) I want to set Task.topic value the same as Lecture.topic this task refers to. For example: lecture1 = Lecture('Awesome topic') lecture1.save() task1 = Task(lecture1) task1.save() # here task1.topic must be 'Awesome topic' I've tried this thing: class Task(models.Model): lecture = models.OneToOneField(Lecture, on_delete=models.CASCADE) topic = models.CharField( max_length=30, blank=False, default=lecture.topic ) but have 'OneToOneField' object has no attribute 'topic' -
How to call a Model Method from an HTML form value
I have a simple HTML form for filtering/ordering the data on the page. This uses a GET request to the view which returns the data from the back-end in the manner which was requested. What I want to do is use a Model Method, instead of an attribute, as the form's input value. Current example which passes Model attribute as input value (current_score is a Model attribute): <input class="form-check-input" id="Radios4" name="ordering" type="radio" value="-current_score"> <label class="form-check-label" for="exampleRadios4">Scores: High-to-Low</label> The problem with this is that current_score returns the quantity of correct questions while I want the user's percentage score on the test. Which is calculated using this Model Method: @property def get_percent_correct(self): dividend = float(self.current_score) divisor = len(self._question_ids()) if divisor < 1: return 0 # prevent divide by zero error if dividend > divisor: return 100 correct = int(round((dividend / divisor) * 100)) if correct >= 1: return correct else: return 0 So my question is, how can I use the Model Method as the input value in the form? Such as: <input class="form-check-input" id="Radios4" name="ordering" type="radio" value="-get_percent_correct"> <label class="form-check-label" for="exampleRadios4">Scores: High-to-Low</label> -
Multiple Input Values For Model Form
I am creating profiles for users and I want them to be able to select multiple tags using forms.ModelMultipleChoiceField which will be saved to their profile. My models.py setup: class ProfileTags(models.Model): description = models.CharField(max_length=300) class Profile(models.Model): user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) name = models.CharField(max_length=50, blank=True) services_offered = models.ManyToManyField(ProfileTags) Forms.py: class ProfileUpdateForm(forms.ModelForm): ProfileTags = forms.ModelMultipleChoiceField(queryset=ProfileTags.objects.all()) class Meta: model = Profile Views.py: def profile(request): if request.method == 'POST': p_form = ProfileUpdateForm(request.POST,request.FILES, instance=request.user.profile) if p_form.is_valid(): p_form.save() messages.success(request, f'Your account has been updated!') return redirect('profile') else: p_form = ProfileUpdateForm(instance=request.user.profile) context = { 'form': p_form } return render(request, 'users/profsettings.html', context) I load in the tags in the ProfileTags model and this seems to have worked and I'm able to allow users to submit the tags and it's saved in the DB successfully, however I am experiencing the following issues: instance=request.user.profile does not seem to work for the checkboxes. After submitting the form, if I go back to the form the boxes aren't checked. I want users to be able to remove tags from their profile by simply unchecking a previously checked box - this may be a template issue as I'm manually rendering the fields, however: It doesn't seem to be possible to delete the tags … -

Restrict all access to admin site unless
Let's say I have a model called "Settings". When someone first logs in to the project (I'm talking about a superuser logging in.) The first thing they should do is populate the Settings models before doing anything. So is there a way I can redirect their login to the Settings model on every login until there's an object or is there a way I can restrict all access or unregister all other models until they populate the settings model? Thanks, -

Pass data from Django template to react App
I'm building an app using Django - DRF - React through template component invocation. Question is: Whats the right way to pass data from django view-template to react app-component, for example, if the api called in app fetch method used a dynamic parameter: fetch("/api/endpoint") to fetch("/api/endpoint/modelPrimaryKey") Sources used: views.py def index(request): return render(request, 'frontend/index.html') index.html ... </body> {% load static %} <script src="{% static "frontend/main.js" %}"></script> </html> main.js (compiled by webpack from this source) class App extends Component { constructor(props) { super(props); this.state = { data: [], loaded: false, placeholder: "Loading" }; } componentDidMount() { fetch("/api/endpoint") .then(response => { if (response.status > 400) { return this.setState(() => { return { placeholder: "Something went wrong!" }; }); } return response.json(); }) .then(data => { this.setState(() => { return { data, loaded: true }; }); }); } render() { return ( ... some jsx ); } } export default App; const container = document.getElementById("app"); render(<App />, container); -
why prefetch_related not working in django?
I have these models class Product(models.Model): product_id = models.AutoField(primary_key=True) product_name = models.CharField(max_length=255, null = False, unique=True) product_title = models.CharField(max_length=255, null = True) product_price = models.CharField(max_length = 255) brand = models.ForeignKey(Brand, on_delete=models.SET_NULL, null=True) product_type = models.ForeignKey(Product_type, on_delete=models.SET_NULL, null=True) class Product_feature(models.Model): product_feature_id = models.AutoField(primary_key=True) feature = models.ForeignKey(Feature, on_delete=models.SET_NULL, null=True) product = models.ForeignKey(Product, on_delete=models.SET_NULL, null=True, related_name='product_features') product_feature_value = models.CharField(max_length=255, null = False) So I want to fetch product_features for each product and i used prefetch_related like this: product_data = Product.objects.filter(brand__brand_id = brand_data.brand_id).prefetch_related('product_features') but in template it's now showing related model data here's template code: {% for products in product_data %} {{ products.product_name }} {% for a in product_data.product_features.all %} <li>{{ a.product_feature_value }}</li> {% endfor %} {% endfor %} Please help me I tried everything but nothing works! -

How to display only one record from child model for each header item in Django ListView using distinct()
I am using two related models in my Django application. The objects so created in the models are being displayed using the listview class. In the child model I can create multiple rows based on some key date. When I try to display values from both the models, all the child objects for the respective FK fields are displayed (wherever more than one records are there). Let me make the situation clearer as below: models.py class MatPriceDoc(models.Model): mat_price_doc_number = models.IntegerField(null=True, blank=True.....) mat_num = models.ForeignKey(Material, on_delete=.......) mat_group = models.ForeignKey(MatGrp, on_delete=.......) doc_type = models.CharField(max_length=2, null=True, default='RF'....) create_date = models.DateField(default=timezone.now,...) class MatPriceItems(models.Model): price_doc_header = models.ForeignKey(MatPriceDoc, on_delete=...) price_item_num = models.CharField(max_length=3, default=10,...) price_valid_from_date = models.DateField(null=True, verbose_name='From date') price_valid_to_date = models.DateField(null=True, verbose_name='To date') mat_price = models.DecimalField(max_digits=7, decimal_places=2, null=True, blank=True,...) views.py class MatPriceListView(ListView): template_name = "mat_price_list.html" context_object_name = 'matprice' model = MatPriceDoc def get_context_data(self, **kwargs): context = super(MatPriceListView, self).get_context_data(**kwargs) context.update({ 'mat_price_item_list': MatPriceItems.objects.distinct().order_by('price_doc_header'), #This is where I have tried **distinct()** }) return context def get_queryset(self): return MatPriceDoc.objects.order_by('mat_num') Now the material price changes periodically and there would always be more than one price item for each material for each key date (price_valid_from_date). My objective is to display the latest price of all those materials for which price documents exist. … -
Django: How to ignore tasks with Celery?
Without changing the code itself, Is there a way to ignore tasks in Celery? For example, when using Django mails, there is a Dummy Backend setting. This is perfect since it allows me, from a .env file to deactivate mail sending in some environments (like testing, or staging). The code itself that handles mail sending is not changed with if statements or decorators. For celery tasks, I know I could do it in code using mocks or decorators, but I'd like to do it in a clean way that is 12factors compliant, like with Django mails. Any idea? Thanks!
