Adding custom javascript audio recording filed to wagtail admin interface
I would like to add custom javascript audio recorder to the admin page in Wagtail. It have been suggested to customize the Time-Date widget which already uses Js. I've modified the original widget to the following code but it seems like it's more complicated than I thought. Demo of the recorder that I want to use is available at Mozilla's MediaRecorder-examples Here is the Js code and html for it. The code so far is: import json from django import forms from django.conf import settings from django.forms import widgets from django.utils.formats import get_format #from wagtail.admin.datetimepicker import to_datetimepicker_format from wagtail.admin.staticfiles import versioned_static # ~ DEFAULT_DATE_FORMAT = '%Y-%m-%d' # ~ DEFAULT_DATETIME_FORMAT = '%Y-%m-%d %H:%M' # ~ DEFAULT_TIME_FORMAT = '%H:%M' class AdminDateInput(widgets.DateInput): template_name = 'wagtailadmin/widgets/date_input.html' def __init__(self, attrs=None, format=None): default_attrs = {'autocomplete': 'off'} fmt = format if attrs: default_attrs.update(attrs) if fmt is None: fmt = getattr(settings, 'WAGTAIL_DATE_FORMAT', DEFAULT_DATE_FORMAT) self.js_format = to_datetimepicker_format(fmt) super().__init__(attrs=default_attrs, format=fmt) def get_context(self, name, value, attrs): context = super().get_context(name, value, attrs) config = { 'dayOfWeekStart': get_format('FIRST_DAY_OF_WEEK'), 'format': self.js_format, } context['widget']['config_json'] = json.dumps(config) return context @property def media(self): return forms.Media(js=[ #versioned_static('wagtailadmin/js/date-time-chooser.js'), versioned_static("css/custom.js") ]) -

Django rq-scheduler: jobs in scheduler doesnt get executed
In my Heroku application I succesfully implemented background tasks. For this purpose I created a Queue object at the top of my views.py file and called queue.enqueue() in the appropriate view. Now I'm trying to set a repeated job with rq-scheduler's scheduler.schedule() method. I know that it is not best way to do it but I call this method again at the top of my views.py file. Whatever I do, I couldn't get it to work, even if it's a simple HelloWorld function. views.py: from redis import Redis from rq import Queue from worker import conn from rq_scheduler import Scheduler scheduler = Scheduler(queue=q, connection=conn) print("SCHEDULER = ", scheduler) def say_hello(): print(" Hello world!") scheduler.schedule( scheduled_time=datetime.utcnow(), # Time for first execution, in UTC timezone func=say_hello, # Function to be queued interval=60, # Time before the function is called again, in seconds repeat=10, # Repeat this number of times (None means repeat forever) queue_name='default', ) worker.py: import os import redis from rq import Worker, Queue, Connection import django django.setup() listen = ['high', 'default', 'low'] redis_url = os.getenv('REDISTOGO_URL') if not redis_url: print("Set up Redis To Go first.

JSON fields serializer errors in Django rest framework

Django Angular Lazy Loading and routing not working

CSRF cookie not set Django cross-site iframe in chrome
I'm trying to use an iframe of my django site in a different domain, however whenever I submit a form, It says the CSRF cookies is not set. This occurs in chrome and safari. I am running Django 3.1.0. I've tried adding the following settings in my settings.py: SESSION_COOKIE_SAMESITE = 'None' SESSION_COOKIE_SECURE = True X_FRAME_OPTIONS = 'ALLOWALL' CORS_ORIGIN_ALLOW_ALL = True CORS_ALLOW_CREDENTIALS = True CSRF_COOKIE_SECURE = False CSRF_COOKIE_SAMESITE = None CSRF_COOKIE_HTTPONLY = False CSRF_TRUSTED_ORIGINS = [ 'otherdomain.com', ] MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', 'corsheaders.middleware.CorsMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', ] Further, I can confirm the csrf token is being set in the form using: {% csrf_token %} Lastly, I've also added the @xframe_options_exempt decorator to the form page. Edit: I am also using the render method to display the form as recommended by the documentation. Edit2: For some more context, this form functions fine when it is used in the host domain (not an iframe) Unfortunately the csrf exempt decorator is not an option for me. I've tried clearing my cookies, though it does not solve my problem. Any help would be greatly appreciated! -
django.db.utils.ProgrammingError: relation "blog_category" does not exist
I started a Django project and I am not sure what I am missing. Prior to this error, I deleted the database, and deleted the migrations as well because I wanted the post to have an UUID. I got this error when I created my docker-compose-prod.yml file and all the django security stuff in the settings.py file(I am assuming all the security code I wrote in the settings.py file work because the warning signs do not show up): django.db.utils.ProgrammingError: relation "blog_category" does not exist As of right now, I am not sure what I am doing wrong? Also, I do not want to delete the migrations or make any changes within the database because I have the "post data" and I remember I ran into this issue a long time ago, but decided to ignore it(Meaning I went with the delete the migrations).

Django REST Framework User Registration Privacy Issue: Looking for best practice to not show exception if user with given email exists already
I am suprised I have not found anything on the web regarding the following issue which I thought should be common? I may just have used the wrong search terms so I am happy to receive links with more info. My problem is that when using ACCOUNT_EMAIL_VERIFICATION = 'mandatory' I want to not give a clue to any user except the owner of an email address whether that mail is registered on my website, i. e. not show a "A user is already registered with this e-mail address." if an existing email is entered. My assumption is that that would require for the registration endpoint to return the same response independent of whether the email exists or not. I see several possible approaches, but none seems to be a good one: Use a custom exception handler to remove the exception in question from the error messages sent. That means I have to somehow identify the abovementioned exception among all error messages sent so I can still keep the others in the response. I guess I have to identify the exception message by a string the actual error message (possibly dependent on language settings?). If there are multiple error messages I … -
Connect to Django Admin over SSH using Apache and Port Forwarding
I would like to be able to restrict access to the Django admin for all requests, except for requests that come from inside the server, after connecting via SSH (which I have set as the default on my Ubuntu server) using port forwarding. I am using Ubuntu OS, and Apache server to serve my Django app with a React front-end here. I came across a wonderful description of how to do this with Nginx here. I also saw that it is possible to use <Location> blocks to restrict access to a URI. Can someone please assist here? -
Empty querydict request.data using Django Rest Framework

SynchronousOnlyOperation error when upgrading from python 3.6 to python 3.7 using django channels
I've been attempting to upgrade python from 3.6 to 3.7 for our Django & Django channels application. With that change, Django throws a SynchronousOnlyOperation anytime any HTTP request is made (even if it has nothing to do with websockets). My guess is that somehow the python upgrade has made the Django check more strict. I believe that django channels is serving both the HTTP requests and websocket requests so it expects all code to be async compliant. How do I get Django channels runserver to run the wsgi app synchronously, while the channel consumers asynchronously. # project/asgi.py application = ProtocolTypeRouter({"http": get_asgi_application(), "websocket": routing}) # project/wsgi.py application = get_wsgi_application() Stacktrace: It's clear to me that the auth middleware that is running for a normal wsgi view is not async compliant, how can I get it to run in a sync environment?

Is there a way to list the column properties of my PostgreSQL tables?
I'm working in a Django project utilizing an old database from the project. The problem is: Migrating with Django don't give me a good fresh database, some fields that should be nullable are not, some are missing, and this breaks the site. The old database is missing some fields too. I need to compare the old database with the new one, but since there are almost 70 tables and lots of columns, I was hoping there is a way to let me visualize this in a easier way... Any ideas? -
How to Convert UTC Time To User's Local Time in Django
I undrestand that this question is repeated, but unfortunately I cannot find any answer. My impression is that Django already takes care of converting server time to local user as long as I have TIME_ZONE = 'UTC' USE_TZ = True in my settings. Even more if the db is postgresql that setting also doesn't matter and every thing will be still converted. however I tried all the followings: {% load tz %} {{ obj.date }} {{ obj.date|localtime }} {{ obj.date | timezone:"Canada/Mountain" }} and only last one works and the rest gives me UTC time. Last one also is not useful as the time would be only correct for users in that zone. I was wondering if I am missing anything here. I have a very simple test model: class TimeObject(models.Model): date = models.DateTimeField(auto_now=True) -

Django REST Framework - Migrate fails when splitting serializers

I am working on a django website, the code works pretty well but I'd like to make a few adjustments in order to make the web more professional. There's a section in the web called latest posts. Here's the code: <!-- Latest Posts --> <section class="latest-posts"> <div class="container"> <header> <h2>Latest from the blog</h2> <p class="text-big">Lorem ipsum dolor sit amet, consectetur adipisicing elit.</p> </header> <div class="row"> {% for obj in latest %} <div class="post col-md-4"> <div class="post-thumbnail"><a href="#"><img src="{{ obj.thumbnail.url }}" alt="..." class="img-fluid"></a></div> <div class="post-details"> <div class="post-meta d-flex justify-content-between"> <div class="date">{{ obj.date }}</div> <div class="category"> {% for cat in obj.categories.all %} <a href="#">{{ cat }}</a> {% endfor %} </div> </div><a href="#"> <h3 class="h4">{{ obj.title }}</h3></a> <p class="text-muted">{{ obj.overview }}</p> </div> </div> {% endfor %} </div> </div> </section> What you can see in the website is this: As you might have noticed, the images aren't adjusted and therefore, the text doesn't look aligned. Is there any code that can adjust this?
