AttributeError: module 'rest_framework.filters' has no attribute 'FilterSet'

[yslhzj]

I was practicing Chapter08.
When I run the program Times the following error, please help fix it, thank you.

AttributeError: module restore _ framework.filters' has no attribute extension FilterSet'

Relevant information:
Djaog 1.11.11.
Python 3.6.
Djangorestframework-3.6.4

Same - the reason is that FilterSet is part of django_filters, not rest_framekwork, so:

...
# remove the "from rest_framework import filters" line
...
from django_filters import FilterSet, AllValuesFilter, DateTimeFilter, NumberFilter 

... 

class CompetitionFilter(FilterSet): 
  ...

@deepesh-packt did a PR fix this? If not, this is still going to cause problems for people following along with the text

I kept playing until I got the correct references from here:

Here

The correct import in Views.py is like this:

from django_filters import rest_framework as filters

and the code for CompetitionFilteris like this

min_distance_in_feet = filters.NumberFilter( field_name='distance_in_feet', lookup_expr='gte') max_distance_in_feet = filters.NumberFilter( field_name='distance_in_feet', lookup_expr='lte')

It worked for me! I was using "name" instead of "field_name" which caused the problem.

I was having success adapting the contents of the book up to chapter 7, for django 4.1.5 and Python 3.10.6 when I ran into this same problem. I made the adjustments suggested here until my comment, but I see that the CompetitionFilter class is not having an effect, I tried to access the URL: http://localhost:8000/drones/competitions/?pilot_name=Penelope+Pitstop&drone_name=WonderDrone and all competitions are returned.

my code is available at: https://github.com/carlosdelfino/Django-RESTful-Web-Services

If you've forked the repo and updated the code to work, remember to file a PR so that the official repository can be updated, instead of telling people to use your repository.

Please, also remember to rename "filter_fields" to "filterset_fields" in the classes with the List suffix (DroneCategoryList, DroneList, and PilotList), else request with filter query parameter will always return list of all the objects.
