Django - models field join to django-table2
I have a django-tables2 table created with data from model Data. Model Data is linked to model Kategorie with "jmeno" (name of Category). And I would like to link field "jmeno" to my table PuDetailTable as category field. Table definition: class PuDetailTable(tables.Table): class Meta: model = Data fields = ("datum", "doklad", "cislo", "popis", "amount", "partner", "zakazka", "stredisko", "ucet", "company", "category") sequence = ("datum", "doklad", "cislo", "popis", "partner", "zakazka", "stredisko", "ucet", "category", "company", "amount") attrs = {'a': {"class": "a2"}, 'th': {'class': 'headline'}} ... category = tables.Column(verbose_name="Kategorie", accessor="ucet__mustek__kategorie__jmeno", attrs = {"td": {'class': 'text-center'}}) Models: class Data(models.Model): ucet = models.ForeignKey(Ucty, on_delete=models.CASCADE, null=True, blank=True) class Ucty(models.Model): cislo = models.IntegerField("Účet", blank=True, null=True) class Mustek(models.Model): ucet = models.ForeignKey(Ucty, on_delete=models.CASCADE) kategorie = models.ForeignKey(Kategorie, on_delete=models.CASCADE) class Kategorie(models.Model): jmeno = models.CharField("Kategorie", max_length=20, blank=True, null=True) And I need help with correct accessor to get "jmeno" (category name) to the table as the accessor accessor="ucet__mustek__kategorie__jmeno" is not working. I have tried different variants like accessor="ucet_ucty__mustek__kategorie__jmeno", but this is also not working. So any idea what should be the correct accessor? -
Quick method to view formatted html in a variable or property during debugging
I am debugging a Django app. During debugging, I've set a breakpoint so I can see a rendered html string stored in a variable.

Then I can formatted so I can read it. This is time-consuming though and I wonder if there is a simple trick or alternative that will allow me to quickly view the formatted html? -

Django How to Load Static and Media files
I am unable to load both static and media images at the same time. My static/images/ folder contains a default profile picture and my media folder contains images uploaded by users. Currently, i am getting the image from the user model and my media folder is working where any uploaded profile images from a user is displayed correctly. However, loading the default profile picture does not work. I have tried setting the default for the imagefield to include the static/images directory and this still does not work. I had a look in the admin panel and found that it returns "http://127.0.0.1:8000/media/static/images/default_profile_picture.jpg". What should happen is something like "http://127.0.0.1:8000/static/images/default_profile_picture.jpg". When loading the default picture it should go straight to the static folder then the images folder and if it is not looking for the default profile picture, it should look in the media folder (which is what it is currently doing). However, it is going straight to the media folder looking for the default profile picture. Any ideas on how to go straight to the static folder to look for the default profile picture whilst also be able to view user uploaded images in the media folder? It is also important … -

How to count values for a key inside a dictionary
i´m new here and in python. I think my problem is very simple, but I can´t solve it. I have a form with a checkbox. I send 4 selected options, and the querydict recognizes them. But when I ask it to print the 4 values, it only brings me the last one. This is my html: I send the form and it goes to def dietPlan in views.py: def dietPlan(request): # Obtengo los datos que vienen del formulario querydict=request.POST print((querydict)) print((querydict['opcionesCena'])) print(len(querydict['opcionesCena'])) But, the prints are: <QueryDict: {'csrfmiddlewaretoken': ['qNAKsaNlPOO3UY7X76sNy1bEuidxd4WDvUlwJXD6BYxA1JTkyra0A86eYMHJfJ3B'], 'opcionesCena': ['AlimentoID352', 'AlimentoID356', 'AlimentoID360', 'AlimentoID364']}> AlimentoID364 13 Only recognize AlimentoID364 (the last one of the 4) and it takes the number of characters in AlimentoID364. I need to count how many values are for the key 'opcionesCena': if there are 4, or 5, or whatever. Could you help me? Thanks in advance -

Google OAUTH 2.0 doesn't show anything in Microsoft Edge (works fine in Chrome)
When clicking on the Continue With Google button, a popup appears (on my website that I created using Django in Python) as expected in Google Chrome asking which account to continue with etc... By doing the same thing in Microsoft Edge, the popup is blank, there is no content. I'm not sure if it's a problem with my code, my OAUTH account or Microsoft Edge itself. This is the popup in Google Chrome (working as normally) This is the popup in Microsoft Edge (not working at all) I expect the top image to be happening in both browsers. Does anyone have any idea why this isn't working in Microsoft Edge? -

Permissions to edit only one field in a Model. Django
I am developing an app which will have different types of users, and the objective is that in a specific Model, it is completed in a community way. Example: 3 types of users: UserTotal, UserParcial, UserBase. Class object name ModelFamily, has 10 fields defined (int,char,date) I need all users to be able to see the class in the admin panel, but depending on which one I can only edit some fields. How could I solve it? I don't have views at the moment, I'm managing everything from the Django Admin panel. Thank you very much for your time! I tried to change the permissions from admin but it is at Object level, not object field. -

why is django-dbbackup in .psql.bin format? Can I decode it?
I just installed django-dbbackup.. All working as per the doc (linked). One thing slightly puzzles me. Why does it dump into a binary format which I don't know how to read? (.psql.bin). Is there a Postgres command to de-bin it? I found by Googling, that it's possible to get a text dump by adding to settings.py DBBACKUP_CONNECTOR_MAPPING = { 'django.db.backends.postgresql': 'dbbackup.db.postgresql.PgDumpConnector', } This is about 4x bigger as output, but after gzip'ping the file it's about 0.7x the size of the binary and after bzip2, about 0.5x However, this appears to be undocumented, and I don't like using undocumented for backups!

I'm struggling to resolve 2 seemingly ireconsilable dependancy clashes
I have 2 libraries which a code base I'm trying to load and run locally use: django-storages==1.10.1 django-pyodbc-azure==2.1.0.0 The problem I have is I either get this error: django-storages 1.13.2 requires Django>=3.2, but you have django 2.2 which is incompatible., or this one if I try to resolve the first error: django-pyodbc-azure 2.1.0.0 requires Django<2.2,>=2.1.0, but you have django 2.2.1 which is incompatible. Resolving one causes a upgrade or downgrade of Django which triggers either one or the other of the above errors. How do I resolve this? Thanks! -

Django not parsing Unity WWWForm multipart/form-data
I have a django backend (3.2.15) with django rest framework (3.13.1) and I have an endpoint where I post a string and a file. When I use postman, it works fine, but using Unity WWWForm library, it doesn't. The problem that I see, is that when I receive the post from Unity, for some reason, is not parse correctly, for instance, if I send only the string value, the request.POST value is set as <QueryDict: {'personal_account': ['13123123123\r\n--e2FxgWvU1dzZvTibOpwyxx07RvZnbNzj2BhnBpUY--\r\n']}> instead of <QueryDict: {'personal_account': ['13123123123']}> as it works with postman. When I include the file in the form, request.POST and request.FILE are simply empty. Here is my code: Unity: List<IMultipartFormSection> formData = new List<IMultipartFormSection>(); formData.Add(new MultipartFormFileSection("file", file, AccountsManager.Instance.uiTransferNotificationsBuy.fileName, "image/jpeg")); formData.Add(new MultipartFormDataSection("string", string)); UnityWebRequest www = UnityWebRequest.Post(url, formData); byte[] boundary = UnityWebRequest.GenerateBoundary(); www.SetRequestHeader("Content-Type", "multipart/form-data; boundary = " + System.Text.Encoding.UTF8.GetString(boundary)); www.SetRequestHeader("x-api-key", apiKey); www.SetRequestHeader("Authorization", PlayerPrefs.GetString("IdToken")); www.downloadHandler = new DownloadHandlerBuffer(); yield return www.SendWebRequest(); Django is a default create method from ModelViewSet Couldn't find any reported issues in both projects. Any idea what might be the issue? Thanks -

Permisos para editar unicamente un campo en un Modelo. Django
estoy desarrollando una app la cual va a tener distintos tipos de usuarios, y el objetivo es que en un Modelo puntual, se complete de manera comunitaria. Ej: Tengo una app que tiene creados 3 tipos de usuarios: UsuarioTotal, UsuarioParcial, UsuarioMinimo. Una clase que es ModeloFamilia, que consta de 10 campos (int, char, date, etc) Puedo hacer que UsuarioParcial vea todo el modelo, pero unicamente pueda editar los 4 primeros campos del mismo? UsuarioTotal pueda ver/editar todo. Y UsuarioMinimo, solo pueda editar 1 campo que coincide con uno de los de UsuarioParcial? Como podria resolverlo? de momento no tengo vistas, estoy manejando todo desde el panel de Admin de Django. Muchas gracias por su tiempo! Probé cambiar los permisos desde admin pero es a nivel Objeto, no campo de objeto.
