By default djanog set a related name with this pattern model_name +
"_set".
but in related_query_name in django/db/models/fields/related.py this is
wrong.
Now is this
```
(
self.remote_field.related_query_name
or self.remote_field.related_name
or self.opts.model_name
)
```
```
and most change to this
(
self.remote_field.related_query_name
or self.remote_field.related_name
or f'{self.opts.model_name}_set'
)
```
suppost we have some model like this:
```
class Collection(models.Model):
title = models.CharField(max_length=255)
featured_product = models.ForeignKey('Product',
on_delete=models.SET_NULL, null=True,)
class Product(models.Model):
title = models.CharField(max_length=255)
description = models.TextField
price = models.DecimalField(max_digits=6, decimal_places=2)
inventory = models.IntegerField
last_update = models.DateTimeField(auto_now=True)
collection = models.ForeignKey(Collection, on_delete=models.PROTECT)
```
this related_name is okay but django will get error beacuse this function
is wrong.
