I am creating a website where users can follow stocks and see articles based on what they follow. I am struggling to get the view that allows users to select which stocks they want to follow to work.
models.py
from django.db import models
from django.contrib.auth.models import User
from django.dispatch import receiver
from django.db.models.signals import post_save
class Stock(models.Model):
name = models.CharField(max_length = 50)
ticker = models.CharField(max_length = 50)
def __str__(self):
return self.name
class Profile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
followed_stocks = models.ManyToManyField(Stock, blank=True)
def __str__(self):
return self.user.username
@receiver(post_save, sender=User)
def update_user_profile(sender, instance, created, **kwargs):
if created:
Profile.objects.create(user=instance)
instance.profile.save()
class Article(models.Model):
stock = models.ForeignKey(Stock, on_delete=models.CASCADE, default = 0 )
title = models.CharField(max_length = 200)
url = models.URLField()
description = models.TextField()
def __str__(self):
return self.title
forms.py:
class StockFollowForm(forms.Form):
stocks = forms.ModelMultipleChoiceField(required =False,
widget=forms.CheckboxSelectMultiple,
queryset=Stock.objects.all())
template:
{% block body %}
<div class = "container">
<h2 class = "text-center">Register</h2>
<form method = 'post'>
{% csrf_token %}
{{ form }}
<div class = "text-center">
<br/>
<button class="btn btn-primary" type = 'submit'>Follow</button>
</div>
</form>
</div>
{% endblock %}
views.py:
def follow_coins(request):
if request.method == "POST":
form = StockFollowForm(request.POST)
if form.is_valid():
request.user.profile.followed_stocks = form.cleaned_data.get('stocks_selected')
request.user.save()
return redirect('index')
else:
form = StockFollowForm()
return render(request, 'core/test.html',{'form': form})
This succesfully displays a form of all Stocks next to checkboxes, but how do I actually capture the data from the checkbox and save it to my database in the test view?
