Django Get Latest Entry from Database

Question

I\'ve got 2 questions, but they are related to the same topic.

I know how to retrieve data from a for loop using template tags

{% for st         


        

Answer 1

Let us assume I have a Model named "OneOfTheModelsUsed" and there is a field called "car_name" and "date" within this model.

The following code worked for me while I was using Django FormWizard. After going through all the steps in the form and it gets saved. I used

last_entry = OneOfTheModelsUsed.objects.latest("date")

This gives all the entries in that model

last_car_name = last_entry.car_name

This gives the specific field entry you want in the given form.

return render(request, 'reference.html', {'last_car_name':last_car_name,}

passed the data to a template.

for the display in the template I used

{{last_car_model}}

and if you need the id for that entry.. use this {{last_car_model.id}} in the template.

PS:I'm fairly new to Django and Web development as a whole so I don't know much of the technical terms for all this
