如何从用户输入来搜索django/python中的内容？

-3

我在python/django中比较新。具有3种型号，例如某些字段：如何从用户输入来搜索django/python中的内容？

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)

我怎么能要求用户输入，例如，“CARD_NUMBER”，并打印出一个HTML页面上的“说明”？

你有没有通过Django的教程了：https://docs.djangoproject.com/en/2.0/intro/ tutorial01 /？ – dvnguyen

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()))

至少类似的东西
