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? -

Email Verification Fail in Django webapp hosted on Elastic Beanstalk with nginx
I was making a web app on Django. I tried to send an email verification link to any new user who registers on my website.

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! (same reason I want to be able to look at the file :-) -

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. -

What is the equivalent of "success" and "complete" from jQuery to Javascript
I currently have a working solution of an ajax jquery where on success it sets an interval of a function for 1 second. On complete it clears the interval and it works perfectly fine. However, i am trying to convert this working ajax jquery to pure javascript and i am having difficulties working out how to convert "success" and "complete". What i have tried is using "onreadystatechange" and check if the ready state is equal to 4 (as the operation is done) and set the interval function and outside the if statement is to clear the interval. Doing this current method does not work as the interval keeps going on each second and i am not sure if it is because my clearInterval function is not getting used or if it is because the readystate is always at 4 so the setInterval function keeps getting run. jQuery(Working perfectly): $(document).on('submit','#post-form',function(e){ e.preventDefault(); $.ajax({ type:'POST', url:'/sendValue/', data:{ value:$('#value').val(), csrfmiddlewaretoken:$('input[name=csrfmiddlewaretoken]').val(), }, success: function success(){ setInterval(displayNewValue, 1000) }, complete: function complete(){ clearInterval(success); }, }); document.getElementById('value').value = '' }); function displayNewValue(){ var test = $("#content"); test.scrollTop(test[0].scrollHeight) } Javascript: document.addEventListener('DOMContentLoaded', () =>{ const post_form = document.getElementById('post-form'); post_form.addEventListener('submit', function(event){ event.preventDefault(); let request = new XMLHttpRequest(); request.open("POST", "/sendValue/", true); … -
