How to get selected value in dropdown list, then pass it to views.py
I'm working on an upload file feature with dropdown and dropzone. But, whenever I submit the uploaded file with selected option, it always says that the selected option is None. I found it None after I printed the nama_bimbingan in views.py. Here it is my code. url.py .... url(r'bimbingan/add/upload', mengelola_bimbingan.upload_data_bimbingan, name='add-bimbingan-excel'), url(r'bimbingan/download-template/', mengelola_bimbingan.bimbingan_template, name='bimbingan-template'), .... forms.py class UploadBimbinganForm(forms.Form): ... ... dropdown_choices = tuple(zip(all_pembimbing, all_pembimbing)) nama_pembimbing = forms.ChoiceField(choices = dropdown_choices) upload_bimbingan.html <form method="POST" action="{% url 'app:add-bimbingan-excel' %}" enctype="multipart/form-data"> {% csrf_token %} <div class="py-3"> <label for="id_nama_pembimbing"> Nama Pembimbing Akademik: </label> <select class="form-control mb-2" id="id_nama_pembimbing" name="nama_pembimbing" required> <option value = "" selected="selected">---------</option> <option value = {{form.nama_pembimbing}}></option> </select> </div> <div id="myDropzone" class="dropzone" drop-zone> <h6 class="dz-message"> Drop file here or click to upload</h6> </div> <div class="py-3"> <a href="{% url 'app:bimbingan-template' %}">Download Template</a><br> <div class="row justify-content-between py-3"> <div class="col-md-5 mb-1"> <a href="{% url 'app:read-all-bimbingan' %}" class="btn btn-blue-outlined">Batal</a </div> <div class="col-md-5"> <input type="submit" value="Simpan" class="btn btn-block btn-blue"> </div> </div> </div> </form> views.py @login_required(redirect_field_name='index') @user_passes_test(only_admin_access) def upload_data_bimbingan(request): form = UploadBimbinganForm(request.POST or None) if request.method == "POST" and 'file' in request.FILES: nama_pembimbing = request.POST.get('nama_pembimbing') excel_file = request.FILES["file"] data = get_data(excel_file, column_limit=1) bimbingans = data["Bimbingan"] ... ... if(len(duplicate) == 0): space_parsed_query = nama_pembimbing.replace(' ', '%20') cleaned_query = space_parsed_query.replace(',', '%2C') nip_pembimbing … -

django NOT NULL constraint failed: " ............... "
I'm new in django and I want to ask you the following question. I have two models: monthly income, that rappresents my single item monthly income and total montly income, that rappresent the summ of all items monthly income. My models.py is the following: from django.db import models from djmoney.models.fields import MoneyField class Vendite(models.Model): ricavi_dalle_vendite = models.CharField(max_length=100, editable=True) ricavi_dalle_vendite_01 = MoneyField(decimal_places=2,default=0, default_currency='EUR',max_digits=11) ricavi_dalle_vendite_02 = MoneyField(decimal_places=2,default=0, default_currency='EUR',max_digits=11) class Totale_Vendite(models.Model): ricavi_tot_dalle_vendite = models.CharField(max_length=100, editable=True) ricavi_01 = MoneyField(decimal_places=2,default=0, default_currency='EUR',max_digits=11) ricavi_02 = MoneyField(decimal_places=2,default=0, default_currency='EUR',max_digits=11) My views is the following: def ricavi_dalle_vendite(request): items = Vendite.objects.all() if request.method == 'POST': form = VenditeModelForm(request.POST) if form.is_valid(): print("Il form è valido") new_input = form.save() else : form = VenditeModelForm() data_jan = list(Vendite.objects.aggregate(Sum('ricavi_dalle_vendite_01')).values())[0] data_feb = list(Vendite.objects.aggregate(Sum('ricavi_dalle_vendite_02')).values())[0] jan = data_jan feb = data_feb total_income = Totale_Vendite(ricavi_01=jan, ricavi_02=feb, id=1) total_income = Totale_Vendite(ricavi_01=jan, ricavi_02=feb, id=1) total_income.save() context= { "form": form, 'items': items, } return render(request, "app/vendite.html", context) The code works well, but when I'm going to delete the first items inserted in the models "Vendite" django give me the error NOT NULL constraint failed: app_totale_vendite.ricavi_01.

How do I store multiple values in a single variable or list in django views.py?
Here is my views.py @login_required def appsc(request): allapplied = Applied_Scholarships.objects.filter(user_id = request.user.id) for applied in allapplied.iterator(): print('hi') sch_id = applied.scholarship_id queryset = ScholarshipDetails.objects.filter(id = sch_id) print(queryset) context = {"object_list":queryset} return render(request,'applied-scholarships.html',context) Here, I need to check the applied scholarships of a student. So for that, I have filtered the entries from the Applied_Scholarship table. Now from that, I took scholarship_id and filtered the entries in ScholarshipDetails table so that I get the name and other details of the scholarship. Now how do I prevent object_list to get overridden? This code gives me value of only 1 scholarship instead of 2. Here is my template: <table class="table mb-0"> <tr> <th>Scholarship name</th> <th>End Date</th> <th>Status</th> <th></th> <th></th> </tr> {% for instance in object_list %} <tr> <td>{{instance.name}}</td> <td>{{instance.end_date}}</td> <td>{{applied.status}}</td> <td><a href = "government/home">{{schdets.link}}</a></td> </tr> {% endfor %} </table> Do I need to use list? If yes, then how? -

Django: How to make model attribute dependent on foreign key present in that model
I have two models in Django : State and City class State(models.Model): #regex = re.compile(r'^[a-zA-Z][a-zA-Z ]+[a-zA-Z]$', re.IGNORECASE) name_regex = RegexValidator(regex=r'^[a-zA-Z]+$', message="Name should only consist of characters") name = models.CharField(validators=[name_regex], max_length=100, unique=True) class City(models.Model): state = models.ForeignKey('State', on_delete=models.SET_NULL, null=True) name_regex = RegexValidator(regex=r'^[a-zA-Z]+$', message="Name should only consist of characters") name = models.CharField(validators=[name_regex], max_length=100, unique=True) postalcode = models.IntegerField(unique=True) In city model I have attribute state which is foreign key from State model. In city model I want to make attribute name dependent on state attribute, as one state will have one city with same name but one city name can be in many states. Like City Udaipur is in both Rajasthan and UttarPradesh in India, but Rajasthan will have single city as Udaipur. -
how to implement function the same as make_password, check_password without Django
I have used Django and handled password with make_password and check_password. however, I get to change a framework to another (other than Django). With another framework, I need to verify passwords that are created by Django because I should use the same database with the data. How to encrypt(make_password) and verify(check_password) the same as Django did without Django? I think it is possible to implement the function like Django's one if I know the internal logic. Password's format stored in database is like that 'pbkdf2_sha256$100000$Dl6Atsc1xX0A$0QFvZLpKdcvcmCNixVCdEA5gJ67yef/gkgaCKTYzoo4=' -
Django duplicate migrations in apps

Accessing other fields in ModelForm
I've got the following model. class FAQ(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE, default=None) question = models.CharField(max_length=100, null=True, blank=False) answer = models.TextField(max_length=500, null=True, blank=False) def __str__(self): return self.user.username I've also got the following ModelForm class FAQForm (forms.ModelForm): class Meta: exclude = ('user',) model = FAQ def __init__(self, *args, **kwargs): super(FAQForm, self).__init__(*args, **kwargs) Within my model form, how can I access the the value within the user field of the FAQ model? I'd like to be able to access it under def init(self, *args, **kwargs): or super(). Thanks so much! -
