How to enable the ltree extension on google cloud sql
First of al: ltree is a postgres plugin, which seems to be officially supported by google (see GCP PostgreSQL extensions) In the same documentation I read that you need to enable the extension first (like on a normal postgres database). My backend application is written in the django framework and I basically instruct it to run the following command, which works without hick ups on my local machine: CREATE EXTENSION IF NOT EXISTS ltree; However, when I run that migration, I get the following error: Traceback (most recent call last): File "/usr/local/lib/python3.7/site-packages/django/db/backends/utils.py", line 82, in _execute return self.cursor.execute(sql) psycopg2.errors.InsufficientPrivilege: permission denied to create extension "ltree" HINT: Must be superuser to create this extension. This makes sense since according to the documentation, "the postgres user must be part of the cloudsqlsuperuser role". However, I see no way to give my user that role. I tried the default postgres user, which according to the documentation page above should be configured correctly, but it basically does not work. When I dig deeper in the cloudsql documentation, I read something even more surprising: it does not seem to be possible to create superusers according to this documentation. So, the question is quite simple: How … -

Django extend base.html work on all pages but one
Today i tried to setup Django authentification on an app and it's working a 99%. The registration and login are working perfectly but i have a problem on the userprofile page. Registration, login and userprofile templates all have the extends base.html and it's working for the registration and login, but on the userprofile page i get an error saying that the source base.html can't be round. Strangest thing is that the path value that Django trie is the correct one, same as the other two templates. This is the structure of my templates folder : Templates Account Registration.html Login.html Userprofile.html Base Base.html Most of the post if have found about extend base error usualy incombe the extend not working at all or not working in one folder but working in the others where mine work for two templates out of 3 in the same folder. I tried to remove most of the code in my userprofile template to see if anything was messing with the extend but even there i get the same error. -

How to descrease SQL queries count generated by model method in Django?

How to save and run python function in HTML button?
Context: For a face recognition project, user should upload a selfie and that pic will be saved in a S3 bucket (AWS) so the final result will be a template with that selfie and the person who looks like you. So, I want a button that save the image uploaded by user and at the same time, run the face recognition function. template: <form method="post" enctype="multipart/form-data" id="upload-form" action="{% url 'erp:fibocal' %}"> <div class="card-footer"> <button type="submit" class="btn btn-primary btn-flat" onclick="showLoaderOnClick('{% url 'erp:fibocal' %}')"> <i class="fas fa-save"></i> ¡Encontrá tu parecido! </button> </div> </form> And that button don´t save the image in my s3 bucket, only runs "erp:fibocal" that is a function in views.py: def fibocal(request): if request.method == 'POST': img_loaded = request.FILES['image'] imagenes = FR(img_loaded) return render(request, 'base.html', {'name': imagenes[0], 'prct':imagenes[1]}) else: return render(request, 'home/register.html', {}) ``` I think that I should save the image at the "fibocal" function but I don´t know how. Thanks! -

403 forbidden when accessing django admin folder
I found many threads about similar problems but nothing worked so far. I'm deploying a web app on production server using uwsgi and nginx. The backend is in Django, frontend in Vue.js. I want to access the Django admin panel. I ran python3 manage.py collectstatic, chown -R www-data:www-data /home/debian/public/static/ and made sure that rights are ok (rwx r-x r-x www-data:www-data for folders and www-data:www-data rw- r-- r-- for files). nginx.conf user www-data; ... location /admin/ { alias /home/debian/public/static/admin/; } When I try accessing the admin panel (https://my-site.com/admin/) I get a 403 forbidden from nginx. error.log from nginx directory index of "/home/debian/public/static/admin/" is forbidden, [...] However, if I go to https://my-site.com/admin/css/base.css, I can see the css file. Other unrelated static folders, such as swagger doc (using drf-yasg), work fine. If I add an index.html file in /home/debian/public/static/admin/, nginx serves the index.html file as expected. Any idea what am I missing ? -

Django - disable a system check for a specific management command
I have a circular problem with a system check in django: $ python manage.py search_index --rebuild -f SystemCheckError: System check identified some issues: ERRORS: {'search.documents.applications': 'entities'}: (search.E001) No elasticsearch index 'entities' exists HINT: Run `manage.py search_index --rebuild -f` to recreate then repopulate the indices. One workaround is to disable this check using system settings but I don't want to have to change system settings to disable it, deploy, run the rebuild, change back, redeploy every time I attach a different search index or flush elasticsearch. Is there a way of disabling this error (eg by overriding that setting) by passing something to the actual manage.py command? -
