I'm relatively new in python/django thing. Having 3 models with some fields for example:
class Card(models.Model):
id = models.AutoField(primary_key=True)
cardtype_id = models.CharField(max_length=10)
holder_name = models.CharField(max_length=100)
card_number = models.IntegerField(default=0)
email = models.EmailField(blank=True)
birthday = models.DateField(blank=True, default=None)
created = models.DateTimeField(default=timezone.now)
updated = models.DateTimeField(default=timezone.now)
strip = models.CharField(max_length=20, default="strip")
def __str__(self):
return self.holder_name
class Transaction(models.Model):
id = models.AutoField(primary_key=True)
description = models.CharField(max_length=100)
class CardTransactions(models.Model):
card = models.ForeignKey(Card, on_delete=models.CASCADE)
transaction = models.ForeignKey(Transaction, on_delete=models.CASCADE)
value = models.DecimalField(max_digits=7, decimal_places=2, blank=True)
value_date = models.DateTimeField(default=timezone.now)
created = models.DateTimeField(default=timezone.now)
description = models.CharField(max_length=200, blank=True)
table_value = models.DecimalField(max_digits=7, decimal_places=2, blank=True)
discount = models.DecimalField(max_digits=7, decimal_places=2, blank=True)
net_value = models.DecimalField(max_digits=7, decimal_places=2, blank=True)
doc_number = models.CharField(max_length=20, blank=True)
How can I ask the user to input, for example, the "card_number" and print out the "description" on a HTML page?
from django.forms import model_to_dict
def my_view(request):
card_num = request.GET.get('cc')
return HttpResponse(str(model_to_dict(Card.objects.filter(card_number=card_num).first()))
at least something like that
You will need to write views and templates to do this task.
One view would be to render the html template where you will have a form to input the value.
Clicking on the button will call another view with parameter card_number which will retrieve the description from the database associated with the card_number and return back to the template where the same can be shown with some div as per your design.
Ajax can be used to call the view and fetch the response.
