I'm new to django, I follow a tutorial from udemy (tweetme) While setting-up rest_framework to load serialized data as json, I get these errors :

TypeError: e.indexOf is not a function in : jquery-3.3.1.min.js:2:82466

and :

Source map error: request failed with status 404 Resource URL: http://127.0.0.1:8000/static-directory/rest_framework/css/bootstrap.min.css Source Map URL: bootstrap.min.css.map

I just used serialized classes and simple view to display my data, (I got the display but still have the error)

The output in my console:

[17/Jun/2018 08:50:24] "GET / HTTP/1.1" 200 5324

[17/Jun/2018 08:50:24] "GET /static-directory/rest_framework/js/csrf.js HTTP/1.1" 304 0 [17/Jun/2018 08:50:24] "GET /static-directory/rest_framework/js/ajax-form.js HTTP/1.1" 304 0 [17/Jun/2018 08:50:24] "GET /static-directory/rest_framework/js/jquery-3.3.1.min.js HTTP/1.1" 304 0

.

//other .css and .js with a success GET (200 and 3xx)

Here is my code:

in "/tweets/models.py":

from django.conf import settings
from django.db import models

class Tweet(models.Model):
    user        = models.ForeignKey(settings.AUTH_USER_MODEL, default = 1,on_delete=models.CASCADE)
    content     = models.CharField(max_length=150, default="")
    boolean     = models.BooleanField(default=True)
    timestamp   = models.DateTimeField(auto_now_add=True)
    updated     = models.DateTimeField(auto_now=True)

in "/tweets/api/views.py":

from rest_framework import generics
from .serializers import TweetSerializer
from tweets.models import Tweet

class TweetListApiView(generics.ListAPIView):
    serializer_class    = TweetSerializer

    def get_queryset(self):
        return Tweet.objects.all()

in "/tweets/api/serializers.py":

from rest_framework import serializers
from tweets.models import Tweet

class TweetSerializer(serializers.ModelSerializer):
    class Meta:
        model   = Tweet
        fields  = [
        "user",
        "content",
        "boolean",
        "timestamp"
        ]

in "/tweets/api/settings.py":

STATIC_URL = '/static-directory/'

STATICFILES_DIRS = [
    os.path.join(BASE_DIR, "static-storage"),
]

STATIC_ROOT=os.path.join(os.path.dirname(BASE_DIR), "static-serve")

N.B: I have no js code I said that I used the code above which uses js from the framework "rest_framework" of django (The framework uses jquery library) (sorry for the wrong answer, I was on my mobile)

Is it a framework issue?

I started a new (clean) django project and did the startup tutorial for django rest framework in : http://www.django-rest-framework.org

by adding this in my urls.py:

from django.conf.urls import url, include
from django.contrib.auth.models import User
from rest_framework import routers, serializers, viewsets

# Serializers define the API representation.
class UserSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = User
        fields = ('url', 'username', 'email', 'is_staff')

# ViewSets define the view behavior.
class UserViewSet(viewsets.ModelViewSet):
    queryset = User.objects.all()
    serializer_class = UserSerializer

# Routers provide an easy way of automatically determining the URL conf.
router = routers.DefaultRouter()
router.register(r'users', UserViewSet)

# Wire up our API using automatic URL routing.
# Additionally, we include login URLs for the browsable API.
urlpatterns = [
    url(r'^', include(router.urls)),
    url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework'))
]

I thank you for your answers
