Filtering multiple model values in Django -




i using django 1.11.4 , python 2.7

so have models

class vehicle(models.model):     auto_maker = (         (‘chevy’, ‘chevrolet’),         (‘ford’, ‘ford’),         (‘nissan’, ‘nissan’),         (‘lamborghini’, ‘lamborghini’),         (‘ferrari’, ‘ferrari’),         (‘dodge’, ‘dodge’),         (‘tesla’, ‘tesla’),         (‘jeep’, ‘jeep’)     )     auto_maker_brand = models.charfield(max_length=12, choices=auto_maker)     model_name = models.charfield(max_length=100)     release_year = models.datetimefield()     added_to_db_date = models.datetimefield()     image_url = models.urlfield(max_length=500)     description = models.textfield()     default_value = models.positivesmallintegerfield(default=0) 

and want able have filter able have last n records of added_to_db_date , of auto_maker_brand objects filtered can use in template

<h1>car maker</h1>      <h2>chevy:</h2>          <!— last 10 added chevy list each 1 in div along image—>      <h2>ford:</h2>          <!— last 10 added ford list each 1 in div along image—> 

and on rest of auto maker brands want include part added_to_db_date returns last 10 added vehicles image , understand how last 10 added in views

def home(requests):     value = vehicle.objects.filter(default_value=0).order_by(‘-id’)[:10]     return render(requests, ‘home.html’, name=‘home’, {‘value’=value}) 

and template so

{% value in value %}     <a href=“#” ><img src=“{{ value.image_url }}/>{{ value.model_name }}</a> {% endfor %} 

but how last 10 added each auto brand filtered me use , able include of them along added on same template?
