Graphene without Django ORM models
I am using 2 DBs (Postgre as primary & Redshift for Big Data). All basic migrations are connected with Postgre DB & ORM based. But, All complex quries for reports & analysis on big data is using Redshift through RAW quries of django. (no Model class or migration on redshift, some external resource dumping data to Redshift). I am struggling to integrate Graphene-Django with my Redshift tables, but Docs mention DjangoObjectType conversion of django model as 1st step, which I don't have in my case. Currently, I am using cursor.execute(query) & cursor.fetchall() to get my results from Redshift tables. How I can bind these tables with Graphene in schema.py. class CategoryType(DjangoObjectType): class Meta: model = Category fields = ("id", "name") -

Select2 on explicit through model in Django admin
Using autocomplete_fields/search_fields in Django's admin works well to cause a Select2 widget to be used for a ForeignKey field, but I'm getting an error when I set things up to have Select2 widgets rendered on a declared through model in a ManyToManyField relationship. My models are different than the following, but using the example from the Django docs where through models in the admin are discussed as a starting point, I have things set up something like this (the example in the docs has an implicit through model, but I have an explicitly declared through model): class Person(models.Model): first_name = models.CharField(max_length=128) last_name = models.CharField(max_length=128) class Group(models.Model): name = models.CharField(max_length=128) members = models.ManyToManyField(Person, through='Membership', related_name='groups') class Membership(models.Model): person = models.ForeignKey('Person', ...) group = models.ForeignKey('Group', ...) and in admin.py: class PersonAdmin(admin.ModelAdmin): inlines = [MembershipInline,] search_fields = ('first_name','last_name,) class MembershipInline(admin.TabularInline): model = Membership autocomplete_fields = ('person',) class GroupAdmin(admin.ModelAdmin): inlines = [MembershipInline,] When I go to the GroupAdmin and try to create a membership, the Select2 widget is rendered, but when I try to look up a person, I get this error: Forbidden (Permission denied): /admin/autocomplete/ Traceback (most recent call last): File "/virtualenvs/my_virtualenv/lib/python3.8/site-packages/django/utils/datastructures.py", line 84, in __getitem__ list_ = super().__getitem__(key) KeyError: 'app_label' During handling … -
Django set/list/array + indexed?
I want to add a SET type column to my Django model. Seems like I can add it with SetTextField(). When I run my Django migrations, I get a longtext column instead of the MySQL set type. db_index=True is ignored. If I try to add an index through the Meta class then it complains with MySQL 1107. Basically, I need something where I can quickly look up if a set contains a string. I.e. check if abc,def contains def, obviously accounting for the commas. Also need to be able to add/remove, although I might get away with just setting a new list. The docs say SetTextField is deprecated and to use JsonField, which I can do and store as [ 'abc', 'def' ], but would I be able to have an index on whether or not "def" is in the list? -
Why isn't my return statement working in react?
I have a piece of code that looks like this: export async function getMyProfile() { try { const response = await Axios.get("http://127.0.0.1:8000/lover/lovers/?jwt=" + token) console.log(myUserId); response.data.forEach(response => { console.log(response.id); if (response.id == myUserId) { console.log("Got response"); return "i hate my life"; } //end if }); } catch (e) { concatBackendSignupErrors(e); return false; } return "fucking die"; } And my console has a record of "Got response" as it should on like 8, but then it prints "fucking die" instead of "i hate my life". AND if I take the return statement that says "fucking die" off, it returns undefined. Why isn't this returning "i hate my life" and how can I fix it? -
Understanding docker compose port wiring for django, react app and haproxy
I came across a docker-compose.yml which has following port configuration: wsgi: ports: - 9090 // ?? Is it by default mapped to host port 80 ?? nodejs image: nodejs:myapp ports: - 9999:9999 environment: BACKEND_API_URL: http://aa.bb.cc.dd:9854/api/ haproxy ports: - 9854:80 I am trying to understand how the port wiring is happening here. nodejs UI app settings needs to specify backend port which is 9854 here. This port is exposed by haproxy setting and is mapped to port 80. I know that wsgi is a django backend app. From its entrypoint.sh (in PS below) and port specification in above docker-compose.yml, I get that django listens to port 9090. But I am unable to get how this port 9090 maps to port 80 (which is then exposed by haproxy at 9854, which in turn is specified in BACKEND_API_URL by nodejs settings). PS: Django wsgi app has following in \wsgi\entrypoint.sh: nohup gunicorn myapp.wsgi --bind "0.0.0.0:9090" And nodejs react app has following in its server.js file: const port = process.env.PORT || 9999; -

Suggestions on using SQLAlchemy with a large vendor oracle database?
We are upgrading a custom application from PHP to Python / Django / SQLAlchemy. The vendor database it is built on is huge... several thousand tables with 100's of columns, multiple keys, and many layers of dependencies. The PHP application uses OCI and SQL to interact with the database. Database queries can involve as many as 10 tables with complex join conditions, and there are 100s of queries in the application. Trying to create models for all these tables doesn't seem practical. Is it possible to use SQLAlchemy without creating models for all these tables?--just execute the sql directly? -

Django-parler fetching translations from the wrong database
I'm a big fan of Django-parler, but I've run into a problem when storing a translated model in two different databases. My model is: class InstrumentFamily(TranslatableModel): primary_key = True translations = TranslatedFields( label=CharNullField(_('Label'), max_length=100, unique=False, null=True,) I have 2 database aliases 'default' and 'test' and my database router directs my model to 'test'. I insert models in both databases by doing this: fam = InstrumentFamily(code=TEST_CODE) with switch_language(fam, 'en'): fam.label = "test_family_test EN" with switch_language(fam, 'fr'): fam.label = "test_family_test FR" fam.save() which stores the object and its translations in database 'test', or by doing this: fam = InstrumentFamily(code="TEST_FAM") with switch_language(fam, 'en'): fam.label = "test_family_default_EN" with switch_language(fam, 'fr'): fam.label = "test_family_default_FR" fam.save(using='default') which saves the object and its translations to database 'default'. So far, so good. But when accessing the object previously saved in 'default' by doing this (after properly clearing all caches to force a database read): fam = InstrumentFamily.objects.using('default').get(code=TEST_CODE) print(f" label: {fam.label}") django-parler properly retrieves the object from database 'default', but looks for the translation from database 'test' !

Django Page Not Found (404) but the current path matched the last one
So.. this is the error: No Category matches the given query. Request Method: GET Request URL: http://127.0.0.1:8000/category/food/ Raised by: blog.views.CategoryArticlesListView This is my view: class CategoryArticlesListView(ListView): model = Article paginate_by = 12 context_object_name = 'articles' template_name = 'category/category_articles.html' def get_queryset(self): category = get_object_or_404(Category, slug=self.kwargs.get('sklug')) return Article.objects.filter(category=category, status=Article.PUBLISHED, deleted=False) def get_context_data(self, **kwargs): context = super(CategoryArticlesListView, self).get_context_data(**kwargs) category = get_object_or_404(Category, slug=self.kwargs.get('slug')) context['category'] = category return context And this is the routing: path('category/<str:slug>/', CategoryArticlesListView.as_view(), name='category_articles') I can't find where I've wronged the code. And the contradictory "Page Not Found" and "the current path matched the last one" is very confusing. -

Use Escaped url in Django url regex mismatch
I'm trying to use an escaped url as a re_path variable for an object identifier in my API. The logic to connect the escaped url to an object is there, but I can't figure out why the regex is not matching. In my head, a GET request with the following url /objects/http%3A%2F%2F0.0.0.0%3A3030%2Fu%2F%3Fid%3Dc789793d-9538-4a27-9dd0-7bb487253da1/foo should be parsed into obj = 'http%3A%2F%2F0.0.0.0%3A3030%2Fu%2F%3Fid%3Dc789793d-9538-4a27-9dd0-7bb487253da1' and field = 'foo' for further processing. Ultimately, returning the object and 200. However I am getting a 404 with a very specific Django error that only proliferates when Django unfruitfully iterates through all the paths available. <HttpResponseNotFound status_code=404, "text/html"> (Pdb) response.content b'\n<!doctype html>\n<html lang="en">\n<head>\n <title>Not Found</title>\n</head>\n<body>\n <h1>Not Found</h1><p>The requested resource was not found on this server.</p>\n</body>\n</html>\n' I know the path exists as when I examine the urlpatterns, the path is present: (Pdb) pp object_router.get_urls() [ ... <URLPattern '^(?P<obj>https?[-a-zA-Z0-9%._\+~#=]+)/(?P<field>foo|bar)\/?$' [name='test-detail-foobar']> ] The url is escaped with urllib.parse.quote(obj.url, safe="") Regexs tried: r"https?[-a-zA-Z0-9%._+~#=]+" r"https?[%23A](www\.)?[-a-zA-Z0-9@:%._\+~#=]{2,256}(\.[a-z]{2,6})?\b([-a-zA-Z0-9@:%_\+.~#?&//=]*)(?=\/foo)" https://regexr.com/6ue7b r"(https?://(www.)?)?[-a-zA-Z0-9@:%.+~#=]{2,256}(.[a-z]{2,6})?\b([-a-zA-Z0-9@:%+.~#?&//=]*)
