How to store and retrieve unstructured SQL primitive key value pairs in Python?
I have some unstructured key value pairs I eventually want to store in a PostgreSQL database using the Django framework. The data are typed using primitive SQL types, so this seemingly sounds trivial. For example: data = { "name": "bob", "size": Decimal("173.4"), "logged_in_at": datetime.now() } However, I can not just create a Model and a table for it because the data are unstructured and can have any field name. (I can ensure though that the name adheres to both Python and SQL syntax rules.) I cannot use JSONField or JSON in general because it cannot process datetime and Decimal reliably. I'm could use a BinaryField to store pickle data but dread the security implications. I could dynamically create serializers for Django REST framework and the related models but dread the necessary abstract meta voodoo and how to deal with changes in the underlying data models during runtime. I took a quick look at MessagePack, it seems to have the same issues as JSON. Protocol Buffers at least have a Timestamp type but do not have a decimal type. Applying ye olde "represent decimals as integers" trick would lose type information and make integer indistinguishable from decimals. Because this is only … -
Why am I getting this error when I try to switch HTML pages
I made basic HTML/CSS files, that I'm trying to run through Django, but every time I run it and try to switch pages, I get this error: Page not found (404) Request Method: GET Request URL: http://127.0.0.1:8000/about.html Using the URLconf defined in test.urls, Django tried these URL patterns, in this order: admin/ [name='main'] add [name='about'] The current path, about.html, didn’t match any of these. Here's what that my .urls file looks like: from django.contrib import admin from django.urls import path from . import views urlpatterns = [ path('admin/', admin.site.urls), path('add',views.about,name='main.html'), path('add',views.about,name='about.html') ] Here's my .views file looks like: from django.shortcuts import render def main(request): return render(request,'main.html') def about(request): return render(request, 'about.html') Lastly Here's the section of my Settings file that I modified to find the file: 'DIRS': [os.path.join(BASE_DIR,'templates')], 'APP_DIRS': True, Is there something else I'm supposed to do to make this work? -
Proper setup of Django with sqlAlchemy?
I have been surfing the web for 3-5 days looking for a proper answer to this solution. I see lots of code for Flask but none for Django to answer my question. Perhaps this is because Django has a built-in ORM, and if it would be considered odd to use SqlAlchemy with Django, I'd like to be made aware of that. It would be a high ranking answer for me personally. The question is: what is the best way (or even one way) to set up Django with sqlAlchemy? I want to: House the initialization of the database in one file if and only if that is what you do in sqlAlchemy to avoid bugs. Keep my database models only in one file, exporting them and then importing into the file(s) where I need them. I do not want to use Aldjemy as seen here. I'm doing this to learn Django An example ideal file structure, this is how i think it should look: ..mysite ....someAppName ......db ......-db.py ......-models.py ....__init__.py ....admin.py ....apps.py ....models.py <-- maybe models should go here, but where to export the db connection from? ....tests.py ....urls.py ....views.py Currently in db/db.py I have: from sqlalchemy import Table, Column, … -
CSRF verification failed behind Route 53
I have a dockerized Django app that utilizes Gunicorn and Nginx. When logging in on the admin page using localhost, no CSRF error emerges. When running the docker on Amazon EC2 with Route 53 as the proxy server (https redirects to http), I get the CSRF error on login. I note the following in my settings.py file (I added the SECURE_SSL_REDIRECT = False but it has had no effect): ALLOWED_HOSTS = ['localhost', '.website_name.ca'] SECURE_SSL_REDIRECT = False # Application definition INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'The6ixDjango.apps.The6IxdjangoConfig', ] MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', ] Given that I have Route 53 on the front-end, is it 'safe' to remove the csrf middleware reference in the MIDDLEWARE list? -

Django: Could not find the GDAL library (OSX)
After my old macbook died I am transferring across a Django Webapp I'd been building to my new machine. I am currently in the process of reinstalling the correct packages and extensions for the app. However I am currently getting the following error when I do python3 manage.py runserver: django.core.exceptions.ImproperlyConfigured: Could not find the GDAL library (tried "gdal", "GDAL", "gdal3.3.0", "gdal3.2.0", "gdal3.1.0", "gdal3.0.0", "gdal2.4.0", "gdal2.3.0", "gdal2.2.0", "gdal2.1.0", "gdal2.0.0"). Is GDAL installed? If it is, try setting GDAL_LIBRARY_PATH in your settings. The database I created was through a server on Postgres.app which I believe comes packaged up with PostGIS, GDAL etc. I have tried following the geoDjango documentation and I added the following in the terminal: export PATH=$PATH:/Applications/Postgres.app/Contents/Versions/14/bin When I run which psql it returns: /opt/homebrew/bin/psql Is this a conflict between a homebrew and Postgres.app installation or something?

Instantiating dependencies (e.g. service clients) in Django
A Django API view calls another service. To call that service, the view needs a client. I'd like to initialize globally an instance of the client and pass that instance to the view. Also, for tests, I'd like to be able to easily mock the client. I can do some terrible hacks (hey, with Python everything is possible!) but I'd like to do it in Django-idiomatic way. I tried as_view(**initkwargs) and passing the instance of the client. The drawback is that in tests I need to modify class variable (and not instance variable, which seems more correct), and also I need to instantiate the client in urls.py which doesn't look like a right place to instantiate such clients (dependencies). I considered having a separate Application in INSTALLED_APPS, but it seems like an overuse of what an Application should do. In my case, the App would only run AppConfig.ready() and would initialize the client for later access by a view. A simple Dependency Injection would do, but I don't want to overcomplicate that, if Django supports equivalent functionality. Where should I initialize such dependencies in Django, and how to later mock them in tests? -

Image of the page contents going to the bottom -
How to serve MEDIA uploads from summernote in prod hosting?
Good afternoon and Happy New Year! In the admin panel, when creating a post, the uploaded images are not displayed. Neither in the admin area nor in the published post. They are in the folder with the downloaded images, and through the Django admin panel, a link is visible (but it does not open, "Not Found The requested resource was not found on this server") and they are uploaded to the hosting (they appear in the django-summernote folder by dates). Tell me how to fix the situation? The statics loaded normally, everything is displayed OK. The only problem is with those files that the user uploads when the post is compiled. .htaccess at the slightest change from the standard one provided by the hoster - the site stops opening. From this and the working statics, I assume that Apache is configured normally, especially since the hoster's infrastructure does not contain a mention or a requirement to change it. Thanks! The settings.py settings are below: STATICFILES_STORAGE = 'whitenoise.storage.CompressedStaticFilesStorage' STATIC_ROOT = os.path.join(BASE_DIR, 'static') STATIC_URL = '/static/' X_FRAME_OPTIONS = 'SAMEORIGIN' SUMMERNOTE_THEME = 'bs4' MEDIA_ROOT = os.path.join(BASE_DIR, 'blog/media/') MEDIA_URL = '/media/' models.py class Post(models.Model): author = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) title = models.CharField(max_length=200) text = models.TextField() … -
Django Admin - How to test @mark_safe condition
I'm trying to implement some code for example: @mark_safe def workers(self): workers_info = [] for name, role in self.workers: workers_info.append( f"<br> Name: {name}" f"<br> role: {role}" ) return '<br><br>'.join(workers_info) return '-' The problem is that my project runs together with sonarCloud and it is saying that I need to cover this part of the code with tests. How can I implement a test without needing to do something like: assert workers == a_giant_block_of_html -
DRF - Nested Serializer Writing Data
This is the model class Memo(BaseModel): memo_text = models.TextField(null=True, blank=True) tag = models.ForeignKey('Tag', on_delete=models.SET_NULL, null=True, blank=True) is_tag_new = models.BooleanField(default=False) class Meta: db_table = 'memo' class Link(BaseModel): url = models.URLField(blank=True, null=True) memo = models.ForeignKey('Memo', on_delete=models.CASCADE, related_name='url') class Meta: db_table = 'link' I have a serializer with nested serializer fields like this class LinkSerializer(serializers.ModelSerializer): class Meta: model = Link fields = ['url'] class MemoSerializer(serializers.ModelSerializer): images = serializers.SerializerMethodField() urls = LinkSerializer(many=True, read_only=True) memo_mark = BookmarkSerializer(read_only=True) tag_name = serializers.SerializerMethodField() tag_color = serializers.SerializerMethodField() def get_images(self, obj): image = obj.image_set.all() return ImageSerializer(instance=image, many=True, context=self.context).data class Meta: model = Memo fields = ['id', 'memo_text', 'is_tag_new', 'memo_mark', 'images', 'urls', 'tag_name', 'tag_color', 'tag', 'created_at', 'updated_at'] def create(self, validated_data): instance = Memo.objects.create(**validated_data) urls_data = validated_data.pop('urls') images_data = self.context['request'].FILES if images_data is not None: for images_data in images_data.getlist('image'): Image.objects.create(memo=instance, image=images_data) if urls_data is not None: for urls_data in urls_data: Link.objects.create(memo=instance, **urls_data) return instance my first problem is that urls is not showing up instead, it shows up like this { "id": 39, "memo_text": null, "is_tag_new": false, "images": [], "tag_name": "URL", "tag_color": "BL", "tag": 4, "created_at": "2022-01-04T04:17:56.221539", "updated_at": "2022-01-04T04:17:56.221539" } the second problem is writing datas to this nested serializer. uploading multiple image works fine, however saving multiple url isn't working.
