Is it possible to access form inputs which are looped with django?
I have this form to answer a survey a user received in a html file. <form method="POST" action="/answerSurvey"> <ol> {% for q in questions %} <li> <label for="questionBody"><b>{{ q.body }}</b></label> <ul style="list-style: none;"> {% for a in answers %} {% if q.id == a.question_id %} <li><input type="checkbox" name="{{ a.id }}"> {{ a.body }}</li> {% endif %} {% endfor %} </ul> </li> {% endfor %} </ol> <button type="submit">Submit</button> </form> I want to create a function to receive the user input to see which questions got ticked. Something similar to @app.route('/answerSurvey', methods=['GET', 'POST']) @login_required def answerSurvey(): question_answers = request.form['something'] so I can store them in a database table with the associated answer.id. -

Custom Django User with Default values
I am using Django 3.2 with Restframework. I have created a custom user for my project and given default values in Models for some fields. But the default values are not accepted when the POST request is made. Like for example, "date_joined" is left blank, then it has to be today's date, but while making request from postman, its taking it as mandatory field. What am I doing wrong? Models.py class MasterUser(AbstractBaseUser): email = models.EmailField(verbose_name='email address',max_length=255,unique=True,) date_of_birth = models.DateField(default="2020-10-10") is_active = models.BooleanField(default=True) is_admin = models.BooleanField(default=False) firstname = models.CharField(max_length=100,blank=True) lastname = models.CharField(max_length=100,blank=True) is_member = models.BooleanField(default=False) date_joined = models.DateField(default=datetime.now) last_signed_in = models.DateTimeField(default=datetime.now) is_subscription = models.BooleanField(default=True) category = models.CharField(max_length=100, null=True) contact = models.CharField(max_length=100, blank=True, unique=True) membership_id = models.CharField(max_length=100, blank=True) objects = MyUserManager() serializer class RegisterUserSerializer(serializers.ModelSerializer): ... ... def save(self): timestamp = int(datetime.now(tz=timezone.utc).timestamp()*1000) account = MasterUser( email = self.validated_data['email'], firstname = self.validated_data['firstname'], lastname = self.validated_data['lastname'], is_member = self.validated_data['is_member'], date_joined = self.validated_data['date_joined'], last_signed_in = self.validated_data['last_signed_in'], is_subscription = self.validated_data['is_subscription'], category = self.validated_data['category'], contact = self.validated_data['contact'], membership_id = hashString(str(timestamp)) ) password = self.validated_data['password'] password2 = self.validated_data['password2'] if password != password2: raise serializers.ValidationError({'password': 'Password doesnt matches'}) account.set_password(password) account.save() return account views.py def registration_view(request): if request.method == "POST": is_member = request.POST.get('is_member') timestamp = int(datetime.now(tz=timezone.utc).timestamp()*1000) serializer = RegisterUserSerializer(data= request.data) data … -

Using a multi-table inheritance model as a through table
I'm trying to use a multi-table inheritance model as a through table, as shown below: class Base(models.Model): ... class Through(Base): ... class RelatedModel(models.Model): ... class Model(models.Model): field = models.ManyToManyField(RelatedModel, through='Base') instance = Model.objects.get(pk=1) related = RelatedModel.objects.get(pk=1) instance.add(related) # ValueError: Can't bulk create a multi-table inherited model However, I keep running into an error when adding a model to the ManyToMany relationship, as to how multi-table inheritance models cannot be bulk created. Is there any way around this? ManyToManyField.add doesn't take a bulk argument so it doesn't seem to be possible to disable bulk creation there. Does anyone know of a workaround for this without getting rid of the inheritance? -

writing django queries for one to many relationships, (django query and taggit)
So i have a model called "Ad", for the sake of my question, let's say this is my model: from django.core.validators import MinLengthValidator from taggit.managers import TaggableManager title = models.CharField( max_length=200, validators=[MinLengthValidator(2, "Title must be greater than 2 characters")] ) tags = TaggableManager(blank=True) where TaggableManager is from django-taggit module In my views, i am implementing search, which gives result filtering results based on title field: from django.db.models import Q class view(View): def get(self, request): strval = request.GET.get("search", False) if strval : query = Q(title__icontains=strval) query.add(Q(text__icontains=strval), Q.OR) ad_list = Ad.objects.filter(query).select_related().order_by('-updated_at')[:10] What i wish to add is: if a user types in keywords which are from a tag rather than a tittle, the result should display the Ads which have those tags. I know it is possible to add this feature as i saw the support for ManyToMany Fields in django queries, but i am not sure if that would work with django taggit. Can someone please help me with this? -
How to convert image url into ImageField - Django
am creating a donation web application. Users are able to fill out a form and there donation is submitted into the database, I was wondering how I can have the user submit a url of an image and save it in the database, and then render it on another page. For example, if the user fills out the form and submits a url like https://images.unsplash.com/photo-1481349518771-20055b2a7b24?ixid=MnwxMjA3fDB8MHxzZWFyY2h8M3x8cmFuZG9tfGVufDB8fDB8fA%3D%3D&ixlib=rb-1.2.1&w=1000&q=80, how would I save this to the database as an Image and not a URL? I should then be able to render it out on another page. Html Form: <label class="label-input100" for="image">Image</label> <div class="wrap-input100"> <input id="phone" class="input100" type="text" name="image" placeholder="Please enter the url of your image" required> <span class="focus-input100"></span> </div> My view: (There is a lot of stuff here that do not pertain to my question, I just included it in case it is needed) def donate(request): if request.method == "POST": title = request.POST['donationtitle'] phonenumber = request.POST['phonenumber'] category = request.POST['category'] quantity = request.POST['quantity'] location = request.POST['location'] description = request.POST['description'] date = datetime.datetime.now().date() ins = Donation(title = title, phonenumber = phonenumber, category = category, quantity = quantity, location = location, description = description, user=request.user, date = date ) ins.save() # New part.

Getting error DecimalFields must define a 'max_digits' attribute
I'm having a problem with these DecimalField types. I have the next model: class Mediciones(models.Model): id = models.AutoField(primary_key=True) nombre = models.CharField(max_length=30, verbose_name='Nombre dispositivo') dispositivo = models.ForeignKey(Dispositivos, on_delete=models.CASCADE) temperatura = models.DecimalField(max_digits=5, decimal_places=2) humedad = models.DecimalField(max_digits=5, decimal_places=2) ruido = models.DecimalField(max_digits=7, decimal_places=2) c02 = models.DecimalField(max_digits=7, decimal_places=2) alerta = models.BooleanField(null=False) fecha = models.DateTimeField(verbose_name="Fecha", blank = False) As you can see, I have four DecimalField, and all of them have defined both "max_digits" and "decimal_places", and max_digits is greater than decimal_places. Despite of that, I'm getting errors "DecimalFields must define a 'max_digits' attribute." when I try to make a migration. Do you know why? Thanks in advance! -
Optimal way to create test requests for Python (Django) REST APIs
I have an API/microservice written in Django which is computational in nature. Depending on the request parameters, the API does some computations and gives an output. I need to test the API by simulating various possible combinations of requests and corresponding responses. A few points to consider about my API: The request consists of around 20 parameters. Each parameter can be of different type, for eg. binary, lists, dictionary, etc. Based on the whole input request, the API does some computation which I need to test. Example of a dummy request with just 3 params: { param1: True/False, param2: list of strings param3: list of dictionaries } Each combination of parameter gives a different output. For example in the above request with 3 params, I can have 2 scenarios to test - by putting param1 as True and False. Similarly I can pass various strings in param2 list ( I have predefined set of eligible strings) and so on. Thus with around 20-25 parameters, I have a lot of requests possible with different combinations of parameters taken at a time. Currently I am storing each request in a file by manually creating the request for various combinations possible. Then I … -
Multiple Login Backend with django rest auth
I am using Django rest auth token authentication for a particular project. There are four different types of users (agent, admin, buyer, seller). I have implemented a custom login serializer with a contact number & password for login. But actually, for agent users, I want only employee id to authenticate the user, I have created the unique employee id. but don't know how to implement a different login backend for this particular user. can you share some ideas for this? For buyer, seller, the default login backend working with no issue. But for agents, I need to implement differently. -
Django - handling guest users
I have a general question about how to best handle the logic for guest users. What I have is a website (sort of HacknPlan clone) and when a non-registered (guest) user accesses the page, he/she can interact with the page (create tasks,...) the same as a registered one, but with limitations. I'm using this logic to determine and create a guest user in a database: class Account: def __init__(self, request): self.request = request def getUser(self): if not self.request.user.is_authenticated: ip = get_client_ip(self.request) if UserAccount.objects.filter(ip_address=ip).exists(): return UserAccount.objects.get(ip_address=ip) random_username = f"{randomString(10)}_guest" random_email = f"{randomString(5)}_guest@example.com" guest_user = UserAccount.objects.create( username=random_username, email=random_email, ip_address=ip, is_active=False ) return guest_user else: return self.request.user As you can see, I'm also adding the IP address to the guest user, so when the guest refreshes or revisits the page, I can get this particular guest from the database. Previously, instead of saving its IP, I was saving the session key, but I noticed the key was changing when for example I would log in with an already registered user. This was causing the creation of a new guest user every time I would log out a registered user. If the guest uses chooses to become a registered one, this I how the … -
Django get_FOO_Display() for range list choices

So the range keys are used to store the point in list. I need the serializer to return the word and not the key. -
How to add a commented line with relative path to the first line of vim file
I am making a Django web app using Vim, and I want to add a commented line to the top of each file, I open or create, with its relative path. For example: # config/urls.py, using c-r and c-% for its relative path. So far I've been working on this bash script. #!/bin/bash echo "Enter file name" read newfile if [[ $newfile = *.py ]]; then `touch $newfile && echo "# $PWD"/"$newfile">>$newfile` vim $newfile; elif [[ $newfile = *.html ]]; then `touch $newfile && echo "<!-- $PWD"/"$newfile -->">>$newfile` vim $newfile; elif [[ $newfile = *.css ]]; then `touch $newfile && echo "/* $PWD"/"$newfile */">>$newfile` vim $newfile; else vim $newfile fi That opens with # /home/menashe/testdir/test1.py. How do I only add the relative path testdir/test1.py? Is it possible to put the Vim commands in the script? How do I append a comment to the first line of a file that isn't empty? Thank you -
Resizing images with django-resized
