[Django]-How to obtain a QuerySet of all rows, with specific fields for each one of them?

In addition to values_list as Daniel mentions you can also use only (or defer for the opposite effect) to get a queryset of objects only having their id and specified fields:

Employees.objects.only('eng_name')

This will run a single query:

SELECT id, eng_name FROM employees

We can select required fields over values.

Employee.objects.all().values('eng_name','rank')

Daniel answer is right on the spot. If you want to query more than one field do this:

Employee.objects.values_list('eng_name','rank')

This will return list of tuples. You cannot use named=Ture when querying more than one field.

Moreover if you know that only one field exists with that info and you know the pk id then do this:

Employee.objects.values_list('eng_name','rank').get(pk=1)

Oskar Persson’s answer is the best way to handle it because makes it easier to pass the data to the context and treat it normally from the template as we get the object instances (easily iterable to get props) instead of a plain value list.

After that you can just easily get the wanted prop:

for employee in employees:
    print(employee.eng_name)

Or in the template:

{% for employee in employees %}

    <p>{{ employee.eng_name }}</p>

{% endfor %}

You can use values_list alongside filter like so;

active_emps_first_name = Employees.objects.filter(active=True).values_list('first_name',flat=True)

More details here

Employees.objects.filter().only('eng_name')

This will give a QuerySet of all rows, but with only the specified fields. It does NOT give a list like the other answers above. It gives your the OBJECT INSTANCES. Watch out; it is objects.filter().only() NOT just objects.only()

It is similar to SQL Query:

SELECT eng_name FROM Employees;

queryset = ModelName.objects.filter().only('field1', 'field2')

You can also use list with field names

field_names = ['product_id', 'name', 'price', 'status']
results = ModelName.objects.all().values_list(*field_names)

# or for example
# results = ModelName.objects.all().values_list(*field_names, named=True)
