Django: unable to create Generic Foreign key object
I'm using Django 2.x I have two models class DynamicUrlObject(models.Model): content_type = models.ForeignKey(ContentType, null=True, on_delete=models.SET_NULL) object_id = models.PositiveIntegerField() content_object = GenericForeignKey('content_type', 'object_id') domain = models.CharField(max_length=255) and class MyModel(models.Model): name = models.Char(max_length=50) my_obj = fields.GenericRelation(DynamicUrlObject, related_query_name='my_obj') I have an object of MyModel and want to create a record for DynamicUrlObject and link same to the MyModel model. I'm doing it something like dy_obj = DynamicUrlObject.objects.get_or_create( content_object=my_existing_obj, domain='http://example.com' ) my_existing_obj.my_obj = dy_obj my_existing_obj.save() But this is not creating a record for DynamicUrlObject and gives an error as django.core.exceptions.FieldError: Field 'content_object' does not generate an automatic reverse relation and therefore cannot be used for reverse querying. If it is a GenericForeignKey, consider adding a GenericRelation. -
In my django admin change_list, there are names with diacritics. How to order them properly?
I'm using it with Python 3.6.5. In my Django 2.1 app, I have a model object like this: class Person(models.Model): name = models.CharField(max_length=64) with some names presenting diacritics. In my admin.py, I have: from django.contrib import admin from .models import Person class PersonAdmin(admin.ModelAdmin): ordering = ['name'] admin.site.register(Person, PersonAdmin) So, this is the default order I got when accessing my change_list admin view: Joseph Josué José Éderson but I need them to show up in this order: Éderson Joseph José Josué Also, I have a sort key to do this trick when I have a list: import locale def sort_key_BR(): locale.setlocale(locale.LC_ALL, "pt_BR.UTF-8") return locale.strxfrm names = ['Joseph', 'Josué', 'José', 'Éderson'] names.sort(key=sort_key_BR()) for n in names: print(n) # Éderson Joseph José Josué Worth to mention, in my project's settings.py, I already have: LANGUAGE_CODE = 'pt-BR' What is the proper way to inform a sort key rather than the default to ordering in Django models? Rather what is a proper way of doing this? -
Simple way to make a file available to user for download
I have a template xls file in the media folder. I want that the user can easily download this file from the page. What is a simple way of doing this?

PostGIS OSM import: the number of features is -1
Disclaimer: it's too specific: anybody can reproduce this with a blank Django project which used gdal, and a download of a file here. I'm using Gdal for Django to check what's inside an OSM file. I've tried to download a dozens files from Geofabrik here. From all those files (osm and pbf) I'm using this small script to get some informations: from django.contrib.gis.gdal import DataSource ds = DataSource(r'C:\blabla\data\mayotte-latest.osm.pbf') for l in ds: print('name: "%s", geom_type.name: %s ' % (l.name, l.geom_type.name)) print(" fields: %s, field_widths: %s" % (l.fields, l.field_widths)) print(" l.num_feat: %s, l.extent: %s" % (l.num_feat, l.extent)) print(" l.field_widths: %s, l.field_precision: %s" % (l.field_widths, l.field_precisions)) print(" l.field_types: %s" % (l.field_types, )) for feat in l: print(feat.get('NAME'), feat.geom.num_points) else: print(" ... no points") And with all files (no exception), I get something very close to: name: "points", geom_type.name: Point fields: ['osm_id', 'name', 'barrier', 'highway', 'ref', 'address', 'is_in', 'place', 'man_made', 'other_tags'], field_widths: [0, 0, 0, 0, 0, 0, 0, 0, 0, 0] l.num_feat: -1, l.extent: (44.85604, -13.1491, 45.45754, -12.46832) l.field_widths: [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], l.field_precision: [0, 0, 0, 0, 0, 0, 0, 0, 0, 0] l.field_types: [<class 'django.contrib.gis.gdal.field.OFTString'>, <class 'django.contrib.gis.gdal.field.OFTString'>, <class 'django.contrib.gis.gdal.field.OFTString'>, <class 'django.contrib.gis.gdal.field.OFTString'>, <class 'django.contrib.gis.gdal.field.OFTString'>, <class … -
How to get user in Django signals
How can you get the user who is saving record in django signals? I am using signals to fill in data when a user marks completed = True via a form.

Celery Redis instance filling up despite queue looking empty
We have a Django app that needs to fetch lots of data using Celery. There are 20 or so celery workers running every few minutes. We're running on Google Kubernetes Engine with a Redis queue using Cloud memorystore. The Redis instance we're using for celery is filling up, even when the queue is empty according to Flower. This results in the Redis DB eventually being full and Celery throwing errors. In Flower I see tasks coming in and out, and I have increased workers to the point where the queue is always empty now. If I run redis-cli --bigkeys I see: # Scanning the entire keyspace to find biggest keys as well as # average sizes per key type. You can use -i 0.1 to sleep 0.1 sec # per 100 SCAN commands (not usually needed).

Django-ORM - selecting the last record by date for each attribute
I have constructed the following query "chain": survey_results = OrganisationSurveyResult.objects.filter(user=user) survey_results = survey_results.filter( created_date__in=survey_results.values( 'user', 'organisation_survey' ).annotate( latest_created_date=Max('created_date') ).values( 'latest_created_date' ) ).annotate( module=F('organisation_survey__survey__module'), score=F('survey_result__normalized_score'), rank=F('survey_result__rank_class'), ).values( 'module', 'score', 'rank', 'created_date' ) Which returns the following entries when iterated: {'created_date': datetime.datetime(2019, 8, 14, 15, 10, 54, 214754, tzinfo=<UTC>), 'module': UUID('151cb049-65c5-4278-8133-610859be6f34'), 'score': 95, 'rank': 'Low'} {'created_date': datetime.datetime(2019, 8, 14, 15, 10, 54, 220694, tzinfo=<UTC>), 'module': UUID('7c5848eb-3090-4819-8eac-166367ab0e65'), 'score': 91, 'rank': 'Low'} {'created_date': datetime.datetime(2019, 8, 14, 15, 10, 54, 226334, tzinfo=<UTC>), 'module': UUID('b894c988-af3d-4ecb-a2a1-c42225b64b71'), 'score': 100, 'rank': 'Low'} {'created_date': datetime.datetime(2019, 8, 14, 15, 10, 54, 232898, tzinfo=<UTC>), 'module': UUID('22edce11-f78e-4b2e-a1de-1ecc7f0518c9'), 'score': 59, 'rank': 'Medium'} The request-response cycle for this API endpoint is 51-89ms. The DB query time is 24-38ms. It was originally 1280ms as I was using a prefetch_related method and looping. It's also passed all tests. It has four record entries for a single user (there are only four modules). Each date in the list of entries is also the last SurveyResult for that module and user. Happy so far. However, my next step is for each of the above entries in the list, I need to obtain the following: for survey_result in survey_results.iterator(): resource = Resource.objects.filter(module=survey_result['module'], rank_class=survey_result['rank']) So, I am adding an extra 4 … -

Inserting a record into a table's ManyToMany field while using multiple databases
My project uses Django's builtin multi-database support and I am trying to synchronize data in 2 different databases by taking a record from one database and inserting it into another one. I have tried to do this in the usual way using the add method of the RelatedManager, but it did not work and did not insert the record in the intermediary table in the second db, but rather did that in the default db. Here is how I did that: I have a Person model which has a ManyToMany field to Dbs model: ... class Person(models.Model): ... tenant_dbs = models.ManyToManyField(to=Dbs, blank=True) and Dbs model which contains a single column with the names of the databases a person can have access to: ... class Dbs(models.Model): person_id = models.CharField(primary_key=True, max_length=20 ) So I want to get some Person, Dbs and intermediary records from the default database and copy them all to another database (let's assume its name is 'secondary'). So I do the following: from core.models import Person from .models import Dbs # here I take the objects from default db as I did not mention any other # db manually and save them in the 'secondary' db. This works fine … -

How to filter against URL with foreign key field in Django REST, overwriting get_queryset method correctly
I am trying to filter my queryset against an url with django REST but can't really get it to work. I want to pass a string in the URL (a project name). According to this string, which is a foreign key, I want to filter my queryset (BuildingGroup). I don't want to use query params but a url filter. I followed the docs but there is not so much on it on the site. This is what I am trying: class ListBuildingGroupProject(ListAPIView): serializer_class = BuildingGroupSerializer filter_fields = 'project' def get_queryset(self): project = self.kwargs['project'] building_groups = BuildingGroup.objects.filter(project=project) result = building_groups.order_by('-creation_date') return result The line building_groups = BuildingGroup.objects.filter(project=project) throws me a KeyError for project. Here are my models. Note that BuildingGroup has one Project. A project can belong to many BuildingGroups. class BuildingGroup(models.Model): description = models.CharField(max_length=500, null=True, blank=True) project = models.ForeignKey(Project, on_delete=models.CASCADE) creation_date = models.DateTimeField(auto_now=False) class Project(models.Model): project_name = models.CharField(max_length=120, primary_key=True, unique=True) start_date = models.DateTimeField(auto_now=False, null=True, blank=True) end_date = models.DateTimeField(auto_now=False, null=True, blank=True) and here my URL: path('project/<str:project_name>', ListBuildingGroupProject.as_view(), name='building-group-project'), Help is so much appreciated!

Dojo: all xhr / ajax calls seem to be synchronous and block other calls
I am working on a CRM we inherited. Long story short - there is a button that calls a php script which should run in background and we don't need to wait for response. request(idata+'transferInTimeExec.php',{ sync: false, preventCache:true, method:'GET' }); Now, the transferInTimeExec.php takes an hour to run, it's a very complex script that deals with weekly timesheets for a recruitment company, processes them, does a lot of DB operations etc. Using Chrome. Every time I press the button to run it, it blocks all the xhr calls until it finishes. CRM is "ajax heavy" and while the script is running, the user can't do anything, not even navigate away from that page. Even when I open a new browser tab and try to do something, it won't do it. If I open the CRM in another browser (Firefox) while the script is running, I can use the CRM. In Network tab - the first one is pending, and as you can see all the subsequential calls to a different Ajax call wait (all have sync:false) I even replaced the whole logic with PHP function sleep(30) to make it just do nothing for 30 seconds before returning anything - same … -
In django, how can I ensure that a specific user is accessing a view?
I would like to be able to check if the user accessing a page is a specific user. For instance, when a user accesses the "Edit Post" page on my blog app, I want to ensure that the user is the author of the post. Currently, I check that the user accessing '/Blog/Edit//' has the blog.change_post permission. However, if a second user (who also has that permission) were to enter the URL to change someone else's post, they would pass that permission check and be able to edit someone else's post. What I want is a @user_passes_test function that check's the user object accessing the view against the author attribute of the post. #/Blog/urls.py urlpatterns = [ ... path('Edit/<int:pk>', views.BlogEdit, name='BlogEdit'), ... ] #/Blog/views.py @permission_required('blog.change_post', login_url='/Portal/login') def BlogEdit(request, pk): post = get_object_or_404(Post, pk=pk) if request.method == "POST": form = PostForm(request.POST, instance=post) if form.is_valid(): post = form.save(commit=False) post.save() return redirect('/Blog', pk=post.pk) else: form = PostForm(instance=post) return render(request, 'Blog/Edit.html', {'form': form}) -

Understanding Django CSRF_COOKIE_SAMESITE and CSRF_TRUSTED_ORIGINS
Obviously I have a problem to understand the impact of Django (2.2.4) settings regarding CSRF parameters in a cross-domain environment. As I have already noticed I have to set SESSION_COOKIE_SAMESITE = None if I want to place my Django application into an iframe of a website with another domain (e.g. Django app on foo.com and iframe on bar.com) in order to send forms on my Django application. However what's about the CSRF parameters? After some trials I noticed that I can only send the Django form in the iframe if I also set CSRF_COOKIE_SAMESITE = Nonein the Django settings. But what is the CSRF_TRUSTED_ORIGINS for? If I set the iframe domain (e.g. bar.com) into the list ['bar.com'] instead of CSRF_COOKIE_SAMESITE = None I can not send the form on my Django app in the iframe. Could anybody explain in what case CSRF_TRUSTED_ORIGINS has any effect? Is it just usable in an environment with one domain and serveral subdomains? Thanks for any hint! -

It is throwing this error: (g-v) root@ubuntu-s-4vcpu-8gb-blr1-01:/home/g-v/src# python manage.py runserver File "manage.py", line 14 ) from exc ^ SyntaxError: invalid syntax I read a few posts that recommended trying out python3 manage.py runserver but when I try that, I get this error: (g-v) root@ubuntu-s-4vcpu-8gb-blr1-01:/home/g-v/src# python3 manage.py runserver -bash: /home/g-v/bin/python3: cannot execute binary file: Exec format error My pip list command outputs: (g-v) root@ubuntu-s-4vcpu-8gb-blr1-01:/home/g-v/src# pip list DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020.

Object of type "" is not JSON serializable
I am trying to create an API and pass the context data in Response but I am getting the error: Object of type TakenQuiz is not JSON serializable Below is the code: taken_quizzes = quiz.taken_quizzes.select_related('supplier__user').order_by('-date') total_taken_quizzes = taken_quizzes.count() quiz_score = quiz.taken_quizzes.aggregate(average_score=Avg('score')) least_bid = quiz.taken_quizzes.aggregate(least_bid=Min('least_bid')) extra_context = {'taken_quizzes': taken_quizzes, 'total_taken_quizzes': total_taken_quizzes, 'quiz_score': quiz_score, 'least_bid': least_bid, 'matching_bids': matching_bids, 'driver_num': driver_num, 'lat_lon_orig': lat_lon_orig, 'lat_lon_dest': lat_lon_dest, 'user_pass': user_pass, 'username': username, 'password': password, } print("extra content is ", extra_context) return Response(extra_context) Here is the context data: extra content is {'taken_quizzes': <QuerySet [<TakenQuiz: TakenQuiz object (1)>]>, 'total_taken_quizzes': 1, 'quiz_score': {'average_score': 0.0}, 'least_bid': {'least_bid': 899}, 'matching_bids': [], 'driver_ num': 0, 'lat_lon_orig': '36.1629343, -95.9913076', 'lat_lon_dest': '36.1629343, -95.9913076', 'user_pass': ('jkcekc', 'efce'), 'username': 'efw', 'password': 'sdf'} The error I believe is because of the queryset in the extra_context, How do I resolve this ? I tried json.dumps but it still doesn't work -
