I"m using the django rest framework to create an API. I have the following models:
class Category(models.Model):
name = models.CharField(max_length=100)
def __unicode__(self):
return self.name
class Item(models.Model):
name = models.CharField(max_length=100)
category = models.ForeignKey(Category, related_name="items")
def __unicode__(self):
return self.name
To create a serializer for the categories I"d do:
class CategorySerializer(serializers.ModelSerializer):
items = serializers.RelatedField(many=True)
class Meta:
model = Category
... and this would provide me with:
[{"items": [u"Item 1", u"Item 2", u"Item 3"], u"id": 1, "name": u"Cat 1"},
{"items": [u"Item 4", u"Item 5", u"Item 6"], u"id": 2, "name": u"Cat 2"},
{"items": [u"Item 7", u"Item 8", u"Item 9"], u"id": 3, "name": u"Cat 3"}]
How would I go about getting the reverse from an Item serializer, ie:
[{u"id": 1, "name": "Item 1", "category_name": u"Cat 1"},
{u"id": 2, "name": "Item 2", "category_name": u"Cat 1"},
{u"id": 3, "name": "Item 3", "category_name": u"Cat 1"},
{u"id": 4, "name": "Item 4", "category_name": u"Cat 2"},
{u"id": 5, "name": "Item 5", "category_name": u"Cat 2"},
{u"id": 6, "name": "Item 6", "category_name": u"Cat 2"},
{u"id": 7, "name": "Item 7", "category_name": u"Cat 3"},
{u"id": 8, "name": "Item 8", "category_name": u"Cat 3"},
{u"id": 9, "name": "Item 9", "category_name": u"Cat 3"}]
I"ve read through the docs on reverse relationships for the rest framework but that appears to be the same result as the non-reverse fields. Am I missing something obvious?

How can I make a time delay in Python?
5 answers
I would like to know how to put a time delay in a Python script.
Answer #1
import time
time.sleep(5) # Delays for 5 seconds. You can also use a float value.
Here is another example where something is run approximately once a minute:
import time
while True:
print("This prints once a minute.")
time.sleep(60) # Delay for 1 minute (60 seconds).
Answer #2
You can use the sleep()
function in the time
module. It can take a float argument for sub-second resolution.
from time import sleep
sleep(0.1) # Time in seconds

Simply put and clear. Thank you for sharing. Retrieving a Foreign Key value with django-rest-framework serializers and other issues with PS PHP module was always my weak point 😁. I am just not quite sure it is the best method

StackOverflow is always a bit confusing 😭 Retrieving a Foreign Key value with django-rest-framework serializers is not the only problem I encountered. Checked yesterday, it works!

Maybe there are another answers? What Retrieving a Foreign Key value with django-rest-framework serializers exactly means?. Will use it in my bachelor thesis
