How to overcome error: 'ManyToOneRel' object has no attribute 'verbose_name' in Django application
In my app I have the following models: class Category(BaseStampModel): cat_id = models.AutoField(primary_key=True, verbose_name='Cat Id') category = models.CharField(max_length=55, verbose_name='Category') class MasterList(BaseStampModel): master_list_id = models.AutoField(primary_key=True, verbose_name='Master List Id') mast_list_category = models.ForeignKey(Category, on_delete=models.CASCADE, null=True, verbose_name='Category') # Other fields ... My BaseModel looks like this: class BaseStampModel(models.Model): created_by = models.ForeignKey(settings.AUTH_USER_MODEL, related_name='%(class)s_created', blank=True, null=True, on_delete=models.SET_NULL, verbose_name='Created by') created_on = models.DateTimeField(auto_now_add = True, null=True, blank=True) With this I am able to display the model objects and create/update instances. In my view, when I want to retrieve the verbose_name from model "Category" using: `model_fields = [(f.verbose_name, f.name) for f in Category._meta.get_fields()]` I am getting the following error in my browser: AttributeError: 'ManyToOneRel' object has no attribute 'verbose_name' If I remove the the FK relationship from the field mast_list_category (make it a simple CharField) I don't get the error. Gone through millions of pages, but no solution yet. Any help is much appreciated. -

How to catch an element from a for loop in Django template?
I'm looping through to different categories and rendering results (of its name and its associated pages). This code is rendering correctly. {% for category in categories %} <div class="row"> <div class="col-lg-4"> <h3><a href="{{category.get_absolute_url}}"></a>{{category.category_name}}</h3> {% for page in category.page_set.all %} <p><a href="{{page.get_absolute_url}}">{{page.page_title}}</p> {% endfor %} </div> </div> {% endfor %} I'd like to catch an specific element inside the for loop (to be precise the 4th one in the forloop counter) and customize it (adding some html and text only to that one). I tried using the forloop.counter like this: {% if forloop.counter == 4 %} <!-- modified content --> {% endif %} But there isn't any results (not showing any changes). Is there any way to do this? -

Django modelformset_factory: how to create field with constant value
Say I have a bakery which bakes 10 pies in a batch (i.e. all 10 pies go into the same oven). The objective is simply to record the weight (in grams) and cost of each pie (in $). Cost = weight * 0.01. So each pie is modelled as a PieRecord object, which has weight and cost: models.py from django.db import models class PieRecord(models.Model): """this will be in a modelformset """ # pie_name is a dummy field just to play with text input pie_name = models.CharField(max_length=20) pie_weight_grams = models.FloatField() # calculated: cost($) = pie_weight_grams * 0.01 cost = models.FloatField(default=0.0) I use modelformset_factory to generate 10 PieRecord forms at a shot, and surface on the web page (see views.py below). My question is: I would like to attach some fields that are specific to each batch of 10 pies (not each pie), e.g.: cook time (minutes, FloatField) cook name (CharField) cook date (DateField) cook temperature (degC, FloatField) If I simply add these fields to my PieRecord class, this would result in the user having to enter the same values 10 times (e.g. cook_name James baked this batch of 10 pies), which results in a lot more data entry than is needed; … -

Django - Display the number of users currently watching a live stream
I'm developing a Django site for a sports streaming service. It is necessary to display the number of users who are currently watching the broadcast. You can watch the broadcast only after authorization. What is the best way to implement this? At the moment I think that the best solution would be to send a js request to the Django server, but I think there is a better way. -

Display option value and text to select
I have a select field populated from the database table 'Grade'. It displays Grade objects instead of 'Grade 1', 'Grade 2', 'Grade 3' etc. How can I populate the select to display the texts. My codes: models.py class Grade(models.Model): grade_id = models.AutoField(primary_key=True) grade_name = models.CharField(max_length=10, default="") class Meta: db_table = 'grade' class Student(models.Model): student_id = models.AutoField(primary_key=True) first_name = models.CharField(max_length=50, default="") last_name = models.CharField(max_length=50, default="") grade = models.ForeignKey(Grade, on_delete=models.CASCADE) class Meta: db_table = 'Student' forms.py class CreateStudentForm(forms.ModelForm): class Meta: model = Student fields = ['grade', 'first_name', 'last_name' ] widgets = { 'grade': forms.Select(choices=Grade.objects.all(), attrs={'id':'selectGrade', 'class': 'form-control'}), 'first_name': forms.TextInput(attrs={'id':'txtFirstName', 'class': 'form-control', 'placeholder': 'First Name'}), 'last_name': forms.TextInput(attrs={'id':'txtLastName', 'class': 'form-control', 'placeholder': 'Last Name'}), } views.py def student_action(request): form = CreateStudentForm() return render(request, 'student.html', {'form': form}) -
Enviroment Variables are not loading into Pytest with ini file
For context, if I run pytest --ds="monolith.settings" or DJANGO_SETTINGS_MODULE="monolith.settings" pytest I see the expected behavior but currently I have a pytest.ini (see below) which I run as pytest -c pytest.ini which throws: django.core.exceptions.ImproperlyConfigured: Requested setting DATABASES, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings. I've been trawling through different solutions such as using toml format, using envs, have followed the pytest-django instructions, and just about everything else I've found with no luck.

how to upload image correctly. Django
I am building a Django application (run in local) and I am having headaches about uploading files/pictures. I have read tons of questions/answers everywhere as well as followed the official doc, but somehow I still have problems. In my models.py: FuncionarioPathFoto = models.FileField( "Foto", upload_to = "images/", db_column= "FuncionarioPathFoto", null= False, blank = False ) In my views (I'm using inline forms, so the code is big): def create_funcionario(request): if request.method == "GET": form = FuncionariosForm form_funcionarioadicional_factory = inlineformset_factory(Funcionarios, FuncionarioAdicional, form=FuncionarioAdicionalForm, extra=1) form_funcionarioaux_factory = inlineformset_factory(Funcionarios, FuncionarioAux, form=FuncionarioAuxForm, extra=1) form_funcionarioarquivo_factory = inlineformset_factory(Funcionarios, FuncionarioArquivo, form=FuncionarioArquivoForm, extra=1) form_funcionarioadicional = form_funcionarioadicional_factory() form_funcionarioaux = form_funcionarioaux_factory() form_funcionarioarquivo = form_funcionarioarquivo_factory() context = { 'form': form, 'form_funcionarioadicional': form_funcionarioadicional, 'form_funcionarioaux': form_funcionarioaux, 'form_funcionarioarquivo': form_funcionarioarquivo, } return render(request, '../templates/funcionarios/form_funcionarios.html', context) elif request.method == "POST": form = FuncionariosForm(request.POST) form_funcionarioadicional_factory = inlineformset_factory(Funcionarios, FuncionarioAdicional, form=FuncionarioAdicionalForm) form_funcionarioaux_factory = inlineformset_factory(Funcionarios, FuncionarioAux, form=FuncionarioAuxForm) form_funcionarioarquivo_factory = inlineformset_factory(Funcionarios, FuncionarioArquivo, form=FuncionarioArquivoForm) form_funcionarioadicional = form_funcionarioadicional_factory(request.POST) form_funcionarioaux = form_funcionarioaux_factory(request.POST) form_funcionarioarquivo = form_funcionarioarquivo_factory(request.POST) if form.is_valid() and form_funcionarioadicional.is_valid() and form_funcionarioaux.is_valid() and form_funcionarioarquivo.is_valid(): funcionario = form.save() form_funcionarioadicional.instance = funcionario form_funcionarioaux.instance = funcionario form_funcionarioarquivo.instance = funcionario form_funcionarioadicional.save() form_funcionarioaux.save() form_funcionarioarquivo.save() messages.success(request, "Funcionário adicionado com sucesso!") return redirect(reverse('lista_funcionarios')) else: context = { 'form': form, 'form_funcionarioadicional': form_funcionarioadicional, 'form_funcionarioaux': form_funcionarioaux, 'form_funcionarioarquivo': form_funcionarioarquivo, } return render(request, '../templates/funcionarios/form_funcionarios.html', context) I put this … -
