django.db.utils.OperationalError: duplicate column name: Email
I want to create a Django app that supports two different kinds of users. For that I have first extended my User by inheriting AbstractUser. Some fields are common to both the types of Users that I want my Django app to support and hence I add those fields in the extended User model. My User model is as follows. class User(AbstractUser): is_a = models.BooleanField(default=False) # a boolean flag to determine if this user is of type a is_b = models.BooleanField(default=False) # a boolean flag to determine if this user is of type b Name = models.CharField(max_length=128) Email = models.EmailField() MobileNumber = PhoneNumberField(null=False, blank=False, unique=True) Age = models.PositiveIntegerField() Gender = models.CharField(max_length=1, choices=GenderChoices) Organisation = models.CharField(max_length=128) Designation = models.CharField(max_length=128) def __str__(self): return self.Name I then make migrations. This is my first ever migration in this project. My migrations file is as follows: # 0001_initial.py # Generated by Django 2.0.1 on 2020-10-01 17:30 from django.conf import settings import django.contrib.auth.models import django.contrib.auth.validators from django.db import migrations, models import django.db.models.deletion import django.utils.timezone import phonenumber_field.modelfields class Migration(migrations.Migration): initial = True dependencies = [ ('auth', '0009_alter_user_last_name_max_length'), ] operations = [ migrations.CreateModel( name='User', fields=[ ('id', models.AutoField(auto_created=True, primary_key=True, serialize=False, verbose_name='ID')), ('password', models.CharField(max_length=128, verbose_name='password')), ('last_login', models.DateTimeField(blank=True, null=True, verbose_name='last login')), … -
Duplicating and then extending Django admin template
I want to copy and extend the admin's change_list.html for my app's model. I override the Django admin index.html to provide a link to a template, link works fine, sends to admin/links which has the following: VIEW def links(request): context = dict( #common variables for rendering the admin template admin.site.each_context(request), ) return render(request, 'links.html', context) I then copied the change_list.html template verbatim because I want to work off this as a starting point because I would like it to look and function similar, with a few modifications. This is where I run into errors: Environment: Request Method: GET Request URL: http://127.0.0.1:8000/admin/links/ Django Version: 3.0.8 Python Version: 3.7.7 Installed Applications: ['grappelli', 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'useraudit', 'encrypted_fields', 'easyaudit', 'multiselectfield', 'algorx'] Installed Middleware: ['django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'sesame.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', 'useraudit.middleware.RequestToThreadLocalMiddleware', 'easyaudit.middleware.easyaudit.EasyAuditMiddleware'] Template error: In template C:\Bitnami\djangostack-3.0.8-0\python\lib\site-packages\grappelli\templates\admin\base.html, error at line 118 Reverse for 'app_list' with keyword arguments '{'app_label': ''}' not found. 1 pattern(s) tried: ['admin/(?P<app_label>auth|useraudit|easyaudit|algorx)/$'] 108 : <!-- Switch --> 109 : {% switch_user_dropdown %} 110 : </ul> 111 : </li> 112 : <!-- Site URL --> 113 : {% if site_url %} 114 : <li><a href="{{ site_url }}">{% trans 'View site' %}</a></li> 115 : {% endif %} 116 … -

I have two built-in python dropdown and I am trying to link them together using Ajax calls. You can see the relevant code in the html: <script> $("#id_city").change(function () { // event on the city dropdown change. var cityId = $(this).val(); $.ajax({ // initialize an AJAX request url: '{% url "city_autocomplete" %}', // set the url of the request (= localhost:5000/app/ajax/city-autocomplete/) data: { 'cityId': cityId // add the city id to the GET parameters }, // dataType: 'json', success: function (data) { $('#preview').html(data); // replace the html response with the <div> content } }); event.preventDefault(); }); </script> <script> $("#id_tag").change(function () { var tagId = $(this).val(); $.ajax({ url: '{% url "city_autocomplete" %}', 'tag': tagId }, success: function (data) { $('#preview').html(data); } }); event.preventDefault(); }); </script> Once I select city, cityId takes the value but tagId returns none and vice-versa. I want to know what is the solution in jQuery, to listen to both dorpdown changes at the same time, or let's say how to merge two on.change() together? -
How to register a user with Email instead of username in Django Rest Framework
I've read tons of stack overflow posts about how to register a user with email instead of username but none of them seem to work, so I'm resetting to my defaults. I tried this and this but I still get 'username is required' back from the API when I try to register user. I think the problem might be that I couldn't find a post that's explicit to Django 3 and uses Django Rest Framework. Below are my models, serializers and views. # models class User(AbstractUser): ROLES = ( ('d', 'Doctor'), ('s', 'Secretary'), ('p', 'Patient'), ) role = models.CharField( max_length=1, choices=ROLES, blank=True, default='p', help_text='Role') class Doctor(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) clinic = models.ManyToManyField( Clinic, related_name="doctors", blank=True) appointment_duration = models.IntegerField(default=20, blank=True) # serializer User = get_user_model() class UserSerializer(serializers.ModelSerializer): class Meta: model = User fields = ('id', 'username', 'password', 'role', 'first_name', 'last_name', 'email', 'phone') extra_kwargs = {'password': {'write_only': True, 'required': True} # viewset class UserViewSet(viewsets.ModelViewSet): queryset = User.objects.all() serializer_class = UserSerializer permission_classes = (AllowAny,) So, how could I register with email instead of username? -

How to speed up backend in electron framework?
I am creating a small project and I used electron for the front end and python for back end. The python is taking voice input and responding accordingly at back end but its too slow when integrated with electron. Is there any way to speed up the process by using Django or flask?
