Django Javascript: How To Use Class Name With Template Tag Inside As Identifier in Function
I am using a for loop to print out all of the posts on my site and each post will have a form that allows users to add that post to a list. I am trying to use ajax to do this so that there is no page refresh. The ajax function works on the first post but on all of the others there are issues. i think that the issues are due to each post having the same class name that is being used to identify it, so this is why i want to use the forloop counter in the class name so that each one has a unique identifier. Here is some relevant code: Javascript: #this is where i want the class to have a tag inside $('.collection_save_form').submit(function(e){ e.preventDefault() const url = $(this).attr('action') const post_id = $(this).attr('name') const collection_id = $(this).attr('id') const text = $(`.saved_text${collection_id}`).text() var saveElement = document.getElementById(`save_btn${collection_id}`); $.ajax({ type: 'POST', url: url, data: { 'csrfmiddlewaretoken': $('input[name=csrfmiddlewaretoken]').val(), 'post_id': post_id, 'collection_id': collection_id, }, success: function(response){ if (saveElement.classList.contains("saved")){ saveElement.classList.remove("saved") $(`.saved_text${collection_id}`).text('Save') } else if (!$(this).hasClass("saved")) { saveElement.classList.add("saved") $(`.saved_text${collection_id}`).text('Saved') } }, error: function(response){ console.log('error', response) } }) }) Code with the form: {% for item in posts %} #irrelevant post data … -
In spite of the fact that I have created the django project in the same conda environment it is showing the ImportError: Couldn't import Django?
I haven't even restartted the system. But I do have other conda environments with django version=1.* and 2.. I am facing this issue in 3. version of django.

Django duplicating block.super content
using in template inheritance as in the docs here I'm getting duplication as shown: In the above photo the commented Google Tag Manager text has been duplicated. Obviously I would like to put the actual tag manager in there, but it's a simpler example for SO this way. Anything I put in my child template tag is duplicated when I call {{ base.super }} I'm using Oscar, so here's my inheritance scheme. oscar/base.html #from oscar module #relevent sections only {% load i18n %} {% load static %} <!DOCTYPE html> <html lang="{{ LANGUAGE_CODE|default:"en-gb" }}" class="{% block html_class %}no-js{% endblock %}"> <head> {% block tracking %} {# Default to using Google analytics #} {% include "oscar/partials/google_analytics.html" %} {% endblock %} </head> my base override # located in my procject at 'oscar/base.html' {% extends 'oscar/base.html' %} {% block tracking %} {{ block.super }} <!-- Google Tag Manager --> <!-- End Google Tag Manager --> {% endblock %} Below is anything else I think could be involved.

Django - allow only one user user/visitor(IP) per view(page)
I would be so grateful if someone could point me in the right direction. Im making a webapp in django where you can move around a webcam. The problem is that maybe 2 or 3 people at once can connect to the website and they all control the camera simultaneously. How could i make the page(view) where you move the camera, accessible to only one user/visitor and limit their time to about 3minutes. After 3 minutes it would cancel the current users session and move on to the next user in the line and so on.. Ideally it would show other users the time they have to wait, till they can control the camera. So.. user1 would be moving the camera(for 3mins), user2 would wait for 3 minutes and user3 would have to wait 6 minutes till his turn. I have tried some stuff with django.contrib.auth but cant get it to work. Anybody? Thanks a lot! -

API Transition : From GraphQL to REST (with Django)
For my current project (stack = Django + API + Vuejs), up to now I used GraphQL for my API (over Django, with graphene-django). But this library and other linked one (such as the one that handles JWTs) are quite abandoned, with bugs and weird things so to be more confident in the future I decided to switch to the well-known Django DRF. The thing is, I'm now quite used to GraphQL system of queries and mutations, which is (maybe because I'm used to it) quite simple in its design and when it comes to start with DRF, I feel kinda lost. Indeed, I think I understood the easiest way is to use both ModelSerializer and ModelViewSet but... I feel it's hiding lots of things under the hood. Like it has default methods (list(), retrieve(),...). What if I want to controll all this by defining only the necessary ? Moreover, I have really specific needs. For instance, update is not just giving all the arguments, update the model and TADAAA. For specific fields I have to perform specific actions. (e.g.: if a particular field is modified, send a mail,...) Maybe the best way for my use case is to use … -
How do I point to Node in a dockerized Django project using django-pipeline?
I'm trying to add django-pipeline to a dockerized Django 3.1 project. However, when I run collectstatic I receive the following error: pipeline.exceptions.CompressorError: b'/usr/bin/env: \xe2\x80\x98node\xe2\x80\x99: No such file or directory\n' My settings.py file includes: PIPELINE = { 'CSS_COMPRESSOR': 'pipeline.compressors.yuglify.YuglifyCompressor', 'COMPILERS': ('pipeline.compilers.sass.SASSCompiler',), 'YUGLIFY_BINARY': str(BASE_DIR.joinpath('node_modules/.bin', 'yuglify')), 'SASS_BINARY': str(BASE_DIR.joinpath('node_modules/.bin', 'sass')), 'STYLESHEETS': { 'twirlmate': { 'source_filenames': ( 'pages/scss/styles.css', ), 'output_filename': 'css/styles.css', }, }, } And my package.json includes: { ..., "dependencies": { "sass": "^1.32.5", "yuglify": "^2.0.0" } } I have other local Django projects that use pipeline, but not Docker, and they work fine, so I'm wondering if it has to do with Node not being installed in the container? Any thoughts/help is appreciated. -

Django save files from FileField in docker container

Set initial value in a form in Django
I have a model in my application: models.py: class bdAccesorios(models.Model): fdClienteAcc=models.CharField(max_length=35) fdProveedorAcc=models.CharField(max_length=60) fdSkuAcc=models.CharField(max_length=30) fdNombreAcc=models.CharField(max_length=60) fdCostoAcc=models.DecimalField(max_digits=8, decimal_places=2) fdUnidadAcc=models.CharField(max_length=30) fdExistenciaAcc=models.IntegerField() fdAuxAcc=models.CharField(max_length=60, default="0") Then, I have a form to add new entries to the model class fmAccesorios(ModelForm): class Meta: model=bdAccesorios fields='__all__' What I can't accomplish is that the form starts with an initial value, so far what I have done in my views is this, but the field shows blank views.py def vwCrearAccesorio(request): vrCrearAcc=fmAccesorios(initial={'fdClienteAcc':"foo"}) ###Here is the problem ### if request.method == "POST": vrCrearAcc=fmAccesorios(request.POST) if vrCrearAcc.is_valid(): vrCrearAcc.save() return redirect('/') else: vrCrearAcc=fmAccesorios() return render(request,"MyApp/CrearAccesorio.html",{ "dtCrearAcc":vrCrearAcc }) MORE INFO: I know that I can use the following code in my form to set initial values def __init__(self, *args, **kwargs): super(fmAccesorios, self).__init__(*args, **kwargs) self.fields['fdClienteAcc'].disabled = True self.fields['fdClienteAcc'].initial = "foo" But I can't use that, because I need the variable "foo" to change dynamically, my ultimate goal is to use the request.user.username variable and then use that variable to get another value from another model
