Hi, i had question in django rest framework
I sent you an e-mail because I had a question.
Currently, my company provides web services using pure django.
As the company grew bigger and bigger,
the direction of development was decided through api communication by separating the front and backend from one django project,
and we are trying to proceed with api communication using the django rest framework.
At this time, do I have to pay the usage fee when I want to develop it using the django rest framework for commercial purposes in the project currently being serviced by the company?
Or if you can use it without paying the usage fee, do you have to disclose the source or any restrictions under the license?

Re: Child data table in Django
Hello DearYou can use djangos prefetch_related in the docs :
prefetch_related()
¶
prefetch_related
(*lookups)¶Returns a
QuerySet
that will automatically retrieve, in a single batch, related objects for each of the specified lookups.This has a similar purpose to
select_related
, in that both are designed to stop the deluge of database queries that is caused by accessing related objects, but the strategy is quite different.
select_related
works by creating an SQL join and including the fields of the related object in theSELECT
statement. For this reason,select_related
gets the related objects in the same database query. However, to avoid the much larger result set that would result from joining across a 'many' relationship,select_related
is limited to single-valued relationships - foreign key and one-to-one.
prefetch_related
, on the other hand, does a separate lookup for each relationship, and does the 'joining' in Python. This allows it to prefetch many-to-many and many-to-one objects, which cannot be done usingselect_related
, in addition to the foreign key and one-to-one relationships that are supported byselect_related
. It also supports prefetching ofGenericRelation
andGenericForeignKey
, however, it must be restricted to a homogeneous set of results. For example, prefetching objects referenced by aGenericForeignKey
is only supported if the query is restricted to oneContentType
.For example, suppose you have these models:
from django.db import models class Topping(models.Model): name = models.CharField(max_length=30) class Pizza(models.Model): name = models.CharField(max_length=50) toppings = models.ManyToManyField(Topping) def __str__(self): # __unicode__ on Python 2 return "%s (%s)" % ( self.name, ", ".join(topping.name for topping in self.toppings.all()), )and run:

Re: Child data table in Django
prefetch_related()
¶
prefetch_related
(*lookups)¶
Returns a QuerySet
that will automatically retrieve, in a single batch, related objects for each of the specified lookups.
This has a similar purpose to select_related
, in that both are designed to stop the deluge of database queries that is caused by accessing related objects, but the strategy is quite different.
select_related
works by creating an SQL join and including the fields of the related object in the SELECT
statement. For this reason, select_related
gets the related objects in the same database query. However, to avoid the much larger result set that would result from joining across a 'many' relationship, select_related
is limited to single-valued relationships - foreign key and one-to-one.
prefetch_related
, on the other hand, does a separate lookup for each relationship, and does the 'joining' in Python. This allows it to prefetch many-to-many and many-to-one objects, which cannot be done using select_related
, in addition to the foreign key and one-to-one relationships that are supported by select_related
. It also supports prefetching of GenericRelation
and GenericForeignKey
, however, it must be restricted to a homogeneous set of results. For example, prefetching objects referenced by a GenericForeignKey
is only supported if the query is restricted to one ContentType
.

from django.db import models class Topping(models.Model): name = models.CharField(max_length=30) class Pizza(models.Model): name = models.CharField(max_length=50) toppings = models.ManyToManyField(Topping) def __str__(self): # __unicode__ on Python 2 return "%s (%s)" % ( self.name, ", ".join(topping.name for topping in self.toppings.all()), )
