Which plugin for Django autocompletion
I'd like to use autocompletion in my Django project but I don't know which plugin to choose. I have ModelMultipleChoiceField in my form like: tags = forms.ModelMultipleChoiceField( label=_("Etiquettes"), queryset=Tag.objects.all(), to_field_name="name", required=False, widget=forms.SelectMultiple(attrs={'class': "form-control form-custom"}) ) I'd like to change it into autocompletion. I know there is Typeahead and Django-autocomplete-light plugins but I don't know which one is better for my case. I want to create tag if it doesn't exist after typing it. I want a field like tags in StackOverflow question form but creating tags too. Thank you if anybody can help me. Best regards. -
Django Cloudinary - how do I supply the cloud name (except in the settings)?
I am building a django 3.1.1 app with a simple cloudinary setup for storing images. I get a weird error Must supply cloud_name in tag or in configuration although I did everything as stated in the package documentation: CLOUDINARY_STORAGE = { 'CLOUD_NAME': 'your_cloud_name', 'API_KEY': 'your_api_key', 'API_SECRET': 'your_api_secret' } The uploads work fine, the images are present in Cloudinary and I even got them to display on the page. Now this error just pops from time to time and I can't seem to find the reason why. -
Only Django Admin pages visible while rest of Site blank in production
Im trying to host my site on heroku on my localhost my project is fine with no issues , on deploying it all I get are blank pages (I inspected it and elements are shown but nothing is visible on webpage)apart from admin pages I installed all the necessary packages as I was deploying that is to say gunicorn and whitenoise as well as setting STATIC_ROOT and STATICFILES_STORAGE .

How can I connect a user model to a custom model in Django?
I have a student model with a one-to-one relationship to the built-in Django User model. My aim is to combine both forms in a single template for registration such that whenever I create a new student, the student object is automatically assigned a user by using Django post_save signals. Below are the code snippets: models.py from django.contrib.auth.models import User from django.db import models # Create your models here. class Student(models.Model): CURRENT_CLASS = ( ('1', 'Form 1'), ('2', 'Form 2'), ('3', 'Form 3'), ('4', 'Form 4'), ) user = models.OneToOneField(User, on_delete=models.CASCADE, null=True, blank=True) first_name = models.CharField(max_length=200, null=True) last_name = models.CharField(max_length=200, null=True) adm_num = models.IntegerField(null=True) form = models.CharField(max_length=1, choices=CURRENT_CLASS, null=True) def __str__(self): return '%s %s' % (self.first_name, self.last_name) forms.py from django.forms import ModelForm from django.contrib.auth.forms import UserCreationForm from django.contrib.auth.models import User from django import forms from .models import Student class CreateUserForm(UserCreationForm): class Meta: model = User fields = ['username', 'password1', 'password2'] class StudentForm(ModelForm): class Meta: model = Student fields = '__all__' exclude = ['user'] views.py def signupPage(request): form = CreateUserForm() student_form = StudentForm() if request.method == 'POST': form = CreateUserForm(request.POST) student_form =StudentForm(request.POST) if form.is_valid() and student_form.is_valid(): user = form.save() username = form.cleaned_data.get('username') messages.success(request, 'Account was created for ' + username) return redirect('student:login') … -

Convert ReturnDict/Serializer.data to normal dictionary in django
In my django application I want to work on serializer.data thus there is a need to convert ReturnDict or OrderDict to normal dictionary. How can I do that ?

Django REST Framework: HyperlinkedModelSerializer: ImproperlyConfigured error
I am trying to serialize my Django models using the HyperlinkedModelSerializer class from Django REST Framework. My application is a dictionary application. I defined the serializer class for a Definition model, DefinitionSerializer, as follows: class DefinitionSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = Definition fields = ["id", "definition", "expression"] The Definition model is defined as follows: class Definition(models.Model): definition = models.CharField(max_length=256) I am trying to return the serialized data in my IndexView as follows: class IndexView(APIView): definitions = Definition.objects.all() serializer = DefinitionSerializer(definitions, context={"request": request}, many=True) return Response(serializer.data) Accessing that view, however, returns the following ImproperlyConfigured error: Could not resolve URL for hyperlinked relationship using view name "expression-detail". You may have failed to include the related model in your API, or incorrectly configured the lookup_field attribute on this field. Does this error have to do with the fact that I am including slugs instead of primary keys in my URLs? For example, the URL associated with the "expression" field in the DefinitionSerializer is: app_name = "dictionary" path("define/<slug:slug>", views.ExpressionView.as_view(), name="expression") How can I make this work? -
Integrating normal HTML form with Django form
What I am trying to do is have a form that has this HTML: <form method="post" action=""> {% csrf_token %} <label>Pick a class:</label> <select id="schedClass" name="schedClass" > <option>Select one</option> {% for i in classes %} <option value="{{ i.id }}">{{ i.name }}</option> {% endfor %} </select> </select> {{ form }} <input type="submit" value="reload"> </form> The problem is that for some reason when I submit, the select schedClass doesn't appear in the link. I think it comes from the fact that it's integrated with a django form, but I have no idea. For clarification, what I am trying to do is have a form that creates an instance of a specific model, and one of the categories is schedClass which is a ManyToManyField, but I can't use a ModelForm since I need the items in the selections to be only ones that are also linked to the user with another ManyToMany. Is there anything to do? -

Django keeps applying migrations
This is making me go insane: when I migrate, my django (3.1.1) completes the task, but seems to forgets about it. If I migrate again it will stop because it's trying to reapply the migrations. Example of the situation: I drop db.sqlite3 I drop everything inside app/migrations (excluded init) I run makemigrations: no problems. I run migrate: no problems. I run migrate again: fails (django.db.utils.OperationalError: table "django_content_type" already exists) Just to make sure I've executed "migrate --plan", confirming that it intends to apply the migrations it just performed.

How to get date input from table created using for loop in django?
So I have passed a context from views.py to my html template. I have created a html table using 'For Loop' in the following way and also added a column with input date field. <table class="table"> <thead style="background-color:DodgerBlue;color:White;"> <tr> <th scope="col">Barcode</th> <th scope="col">Owner</th> <th scope="col">Mobile</th> <th scope="col">Address</th> <th scope="col">Asset Type</th> <th scope="col">Schhedule Date</th> <th scope="col">Approve Asset Request</th> </tr> </thead> <tbody> {% for i in deliverylist %} <tr> <td class="barcode">{{i.barcode}}</td> <td class="owner">{{i.owner}}</td> <td class="mobile">{{i.mobile}}</td> <td class="address">{{i.address}}</td> <td class="atype">{{i.atype}}</td> <td class="deliverydate"><input type="date"></td> <td><button id="schedulebutton" onclick="schedule({{forloop.counter0}})" style="background-color:#288233; color:white;" class="btn btn-indigo btn-sm m-0">Schedule Date</button></td> </tr> {% endfor %} </tbody> Now I would like to get that date element value in javascript, but its proving difficult since I am assigning a class instead of id(as multiple elements cant have same id). I tried in the following way but its not working. The console log shows no value in that variable. <script> //i is the iteration number passed in function call using forloop.counter0 function schedule(i){ var deldate = document.getElementsByClassName("deliverydate"); deldate2 = deldate[i].innerText; console.log(deldate2); //log shows no value/empty console.log(i); //log shows iteration number </script> -

Best way to use image files with database data in Django?
I'm new to programming and to Django so forgive me if this is an easily-answerable question but I haven't managed to find any solid answers. I'm currently working on a tour booking website. I want to add several images to a tour in the Tour class, so that on the tour detail page the user can scroll through the photos. I'm referencing this page https://medium.com/ibisdev/upload-multiple-images-to-a-model-with-django-fd00d8551a1c for how to write the model, but this method is for users uploading files, so it doesn't explain how to use ones that I already have. How should I deal with these files? As the link explains, I'm hoping to use an image album class and then use that album in the Tour class, so that I can use several photos for each tour rather than just one image field. I've seen that you can put images in the database directly, but it seems like it's not the best solution. Should they be stored in the static folder? If so, how can they be associated with the correct tour in the Tour class? If they should be stored in the database, how can I call those images from the database and have them displayed in … -
