Django PhoneNumberField library giving problem when using bootstrap class
I am using PhoneNumberField library. But when I access the field and give bootstrap class, the layout changes. It displays PhoneNumberPrefixWidget in one line and PhoneNumberField in another line. I want them to display next to each other. I tried using for loop but I still couldn't get what I want. forms.py phone_no = PhoneNumberField( widget=PhoneNumberPrefixWidget(attrs={'class': 'form-control'}) ) In settings.py PHONENUMBER_DB_FORMAT = 'NATIONAL' PHONENUMBER_DEFAULT_REGION = 'BT' In my html template {{ form.phone_no }} Is there a way to access this fields separately? By default when I access {{form.phone_no}}, both the fields appear together Thanks in advance -
Chartjs splitting double digit numbers
I have seen this question asked a few times but I couldn't find a solution that worked for me. I am passing a Django variable into Chartjs to plot, all of the single-digit numbers are correct but it turns double-digits into single. Like 11 is 1,1...23 is 2,3. I have tried a bunch of different ways but cant figure it out, I appreciate any help you can offer. var home_runs = '{% for game in all_games.home_ten %}{{ game.runs }}{% endfor %}' var ctx = document.getElementById('runChart').getContext('2d'); var runChart = new Chart(ctx, { type: 'line', data: { labels: labels, datasets: [ { label: home_team, data: home_runs }, { label: away_team, data: away_runs, ], } ] }, options: { responsive: true, }, }); -

How to send the current form tab in a request.POST via JavaScript

Confused between OPTIONS request and GET request
I am totally new to REST and django-restframework and I am lost. In normal Django forms we have a form with the ForiegnKey field populated as dropdpwn. A user can select any option from that list. But I am not able to grasp how it is supposed to work in django-restframwork. I want to expose APIs for frontend developer so that they can know what options they can make available to a user and what options are already selected, if it is an update, for example. Doing some reading on SO and other sites I came across OPTIONS request and metadata. It does expose available choices for a ForeignKey field when I make OPTIONS request in browseable API. But I am confused and unsure whether it is what my frontend developers would expect or I will have to rework on it. This problem is not related code so I am not posting any code. It is general about my understanding and confusion of how I am supposed to expose available choices to frontend developers. What is wrong with using SerializerMethodField to send available choices instead of using of metadata(for OPTIONS request)? Why shouldn't we send the available choices in GET … -
TypeError: Cannot cast AnonymousUser to int. Are you trying to use it in place of User?

Many to one relationship search and serialization in django rest framework
I am kinda new to Django and trying to understand how I can search in different models and create nested serializer. This is the simple model file that I have class Company(models.Model): company_name = models.CharField(max_length=50) mail = models.EmailField(null=True, blank=True) NIF = models.CharField(max_length=9, null=True, blank=True) class Office(models.Model): company = models.ForeignKey(Company) office_name = models.CharField(max_length=50, default='Main') direction = models.CharField(max_length=50) class Employee(models.Model): office = models.ForeignKey(Office) employee_ name = models.CharField(max_length=50) mail = models.EmailField(null=True, blank=True) here the company has many offices and offices have many employees. So I am creating a search API in which a user can search the company_name or office_name or employee name and get the data in a relational format like this; company: { ------- office: { ------ Employee: { ------ } } } now my problem is filtering the data and serializing it in this format. I tried this Nested Serialization for serialization and also tried filter from here filter in django but not able to come up with the solution. Note: I am creating Django API by using django-rest-framework -

Django - How to display multpile choices for Polls app
Following along the Django polls app tutorial, I was wondering if instead of having a Charfield for the choice Model and manually adding every response/choice to the database; Is it possible to have choices? For example: class Poll(models.Model): text = models.CharField(max_length=255) pub_date = models.DateField() def __str__(self): return self.text class Choice(models.Model): question = models.ForeignKey(Poll, on_delete=models.CASCADE) choice_text = models.CharField(max_length=255) votes = models.IntegerField(default=0) def __str__(self): return "{} - {}".format(self.question.text[:25], self.choice_text[:25]) You have standard choices for every Poll like this: class Poll(models.Model): text = models.CharField(max_length=255) pub_date = models.DateField() def __str__(self): return self.text class Choice(models.Model): VOTING_CHOICES = ( ('Aye', 'Aye'), ('Nay', 'Nay'), ('Abstain', 'Abstain'), ) question = models.ForeignKey(Poll, on_delete=models.CASCADE) choice_text = models.CharField( max_length=7, choices=VOTING_CHOICES, default='Aye', )** votes = models.IntegerField(default=0) def __str__(self): return "{} - {}".format(self.question.text[:25], self.choice_text[:25]) Does that make sense? Every time I try to implement this, I either get an empty dictionary response when I POST from the form or the options show up in tuples(or do not render at all). -
