Using Django authenitcation with Angular frontend
I wish to use Django's inbuilt user authentication but my frontend is currently all Angular. The login/user status should be shown on the navbar with an option to login/logout. I can't find a guide on this anyway and what I have tried so far isn't giving me any results. I have tried rendering the nav bar in django by using 'app-nav-bar' to reference the angular component and I have also tried moving all the html from angular into django and using the verbatim tag to try and keep the angular functionality but these haven't worked. Navbar Component: <nav class="navbar navbar-expand-lg navbar-dark bg-dark"> <a [routerLink]="['']" class="navbar-brand"> <img src="../static/ang/assets/images/logo.svg" alt="Logo" height="30px"> </a> <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNavAltMarkup" aria-controls="navbarNavAltMarkup" aria-expanded="false" aria-label="Toggle navigation"> <span class="navbar-toggler-icon"></span> </button> <div class="collapse navbar-collapse"> <div class="navbar-nav"> <a [routerLink]="['/view']" class="nav-item nav-link">View Projects</a> <a [routerLink]="['/manage']" class="nav-item nav-link">Manage Projects</a> </div> </div> </nav> Django template: //app-nav-bar had been going in here to test <app-root> <div class="container-fluid"> <div class="row align-items-center"> <div class="col text-center"> <div class="spinner-border p-5 m-5" role="status"> <span class="sr-only">Loading . . .</span> </div> </div> </div> </div> </app-root> I am expecting the navbar to have the same functionality in django as it does in angular but the links arent working or the navbar isnt … -

'ValueError: Required parameter not set' Django app following AWS configuration and Heroku deployment
I have just deployed my Django app to Heroku, having configured the app to store media files in an AWS S3 bucket. Everything was working correctly in the development server, but when I try to access pages containing these images in the Heroku-hosted version, I receive a ValueError informing me that the required parameter 'name' hasn't been set. A look through the traceback suggests that the supposedly nameless objects are the images. s3boto3 is also referenced. My configuration for AWS is detailed below: # settings.py AWS_ACCESS_KEY_ID = os.environ.get('AWS_ACCESS_KEY_ID') AWS_SECRET_ACCESS_KEY = os.environ.get('AWS_SECRET_ACCESS_KEY') AWS_STORAGE_BUCKET_NAME = os.environ.get('AWS_STORAGE_BUCKET_NAME') AWS_S3_REGION_NAME = os.environ.get('AWS_S3_REGION_NAME') S3_USE_SIGV4 = os.environ.get('S3_USE_SIGV4') AWS_S3_FILE_OVERWRITE = False AWS_DEFAULT_ACL = None DEFAULT_FILE_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage' # env.py os.environ.setdefault("AWS_ACCESS_KEY_ID", "**********") os.environ.setdefault("AWS_SECRET_ACCESS_KEY", "**********") os.environ.setdefault("AWS_STORAGE_BUCKET_NAME", "**********") os.environ.setdefault("AWS_S3_REGION_NAME", "eu-west-2") os.environ.setdefault('S3_USE_SIGV4', 'True') I've read suggestions that I may need to add an AWS_SESSION_TOKEN to the configuration, but I have no idea how to go about identifying mine. I've also read elsewhere that a session token isn't a necessary part of the configuration. I'm just looking for a steer so that I don't wind up wasting time attempting something which isn't going to fix the problem. -
Debugging while developing Django apps
I'm aware of pdb built-in Python library for debugging Python programs and scripts. However, you can't really use it for debugging Django apps (I get errors when I try to use it in views.py). Are there any tools that I can use when Django's traceback isn't helpful ? -

checkbox getlist return nothing - django
I am using checkbox in this way: <input type="checkbox"name="group1"value="0"> <input type="checkbox"name="group1"value="1"> <input type="checkbox"name="group1"value="2"> <input type="checkbox"name="group1"value="3"> in my view.py boxes = request.POST.getlist("group1") Which the boxes is an empty array.

So I am not sure is this javascript affect the getlist: $('input[type="checkbox"]').on('change', function() { $('input[name="' + this.name + '"]').not(this).prop('checked', false); }); But I have also tried to disable the javascript, still not working -

Django: How to Access Installed Third Party App's Model and Data
I have been using django-river(https://github.com/javrasya/django-river) application within my app (https://github.com/rupin/WorkflowEngine) I have used the Django rest framework in my application and would like to get the data from the django-river tables. The name of the table is State. My serializer is as follows from river.models import State from rest_framework import serializers class StateSerializer(serializers.Serializer): class Meta: model = State fields = ['id', 'label'] Also, my API view is as follows from rest_framework import generics from workflowengine.riverserializers.StateSerializer import StateSerializer from river.models import State class StateList(generics.ListAPIView): serializer_class = StateSerializer def get_queryset(self): return State.objects.all() Through the Admin console, I have added 11 states inside my state table, which I have checked with pgadmin. When i access the API through the browser, I get 11 empty sections in my API ( no error, just the data is missing). I cant seem to understand how the 11 data points presented in the API are empty. That it presented 11 elements, but no data, which is pretty weird. -
How to get and set the page number in django listview with pagination?
In our application, we have some Records and RecordSets and the RecordListView page shows Records of a RecordSet: class RecordListView(PaginationMixin, ListView): paginate_by = 10 def get_queryset(self): record_set_pk = self.kwargs.get('record_set') recordSet = RecordSet.objects.get(pk=record_set_pk) self.recordSet = recordSet self.queryset = recordSet.record_set.all().order_by('title') return self.queryset The problem is that 'Record' have an attribute named checked and I want to navigate to the page that the last checked record is in there! (or the first not checked record) I have found that self.kwargs.setdefault('page', desired_page_number) shows the desired page but it freezes the page and disables the navigation. So I tried to set a condition to check page argument value but self.kwargs.get('page') is always None. However I found that I can get page number from in str(self.request) but I think it's a little messy and there must be a better solution. Isn't there?! -
Rest_framework_swagger without authorization in Django
I have the following settings for REST_FRAMEWORK in my django project: REST_FRAMEWORK = { ...

I know that by default swagger doesn't show the methods you don't have access to. How can I override it? I have already tried to experiment with SWAGGER_SETTINGS in my settings.py file but it seems to me that is hasn't 'no authorization' option. -

OSMGeoAdmin: Imported OSM maps: points, lines and roads are ok, not multipolygons
Download an OSM map from geofabrik. Import it with osm2pgsql (basic commands, no fancy stuff) You will have your tables ready to use. Here's are my models (all the same fields for Line, Polygon, Point and Roads, just one is enough): class PlanetOsmLine(models.Model): class Meta: db_table = 'planet_osm_line' managed = False osm_id = models.BigIntegerField(primary_key=True) # ...tons of other field (unused)... way = GeometryField(default=None) Now, to display it in the admin interface, basic admin.ModelAdmin does the job and it work, like this for a road: Let's add the OSMGeoAdmin interface with this code: class PlanetOsmAdmin(OSMGeoAdmin): pass my_admin_site.register(PlanetOsmLine, PlanetOsmAdmin) my_admin_site.register(PlanetOsmPolygon, PlanetOsmAdmin) my_admin_site.register(PlanetOsmPoint, PlanetOsmAdmin) my_admin_site.register(PlanetOsmRoads, PlanetOsmAdmin) You'll get this, which is way nicer: OSM Admin works with everything except polygons. Here's the basic view: And when I do my_admin_site.register(PlanetOsmPolygon, PlanetOsmAdmin) then I get only this, always the same place: If the polygons are displayed properly without OSMGeoAdmin, and are not displayed properly with it. There's no error in the console log of Chrome. What am I missing? -
Django Performance | Recalculating a field value in all related models after updating a model in Django

How can I update associated models in a django DeleteView
I have a couple of models, Content and Hostname.
