Modify datetime value in result of F() expression
I am trying to modify datetime value while making filter. I need to make each scheduled_for value to 02:00 AM next day and compare this date to other field. So at first I add 1 day with timedelta(days=1) and then in annotation I try to replace hours and minutes: bookings = Booking.objects.filter( cancel_time__isnull=False ).annotate( invoice_date=ExpressionWrapper((F('scheduled_for') + timedelta(days=1)), output_field=models.DateTimeField()) ).annotate( invoice_time=F('invoice_date').replace(hour=2, minute=0, second=0, microsecond=0) ).filter(invoice_time__gte=F('cancel_time')) But that thing doesn't work and I got error: AttributeError: 'F' object has no attribute 'replace' Is there any way to accomplish what I am trying to do? P.S.: Also I am not sure should I use DurationField or DateTimeField as output_field in ExpressionWrapper. -

Source page instead of page and wrong validation
Below is the code to write comments and reply to. I used django 2.2 and jQuery (Ajax part) here. I have a problem with reply to comment forms. When I press "Add answer" (no data in form) the source of the page appears instead of validation. If I add text and press "Add answer" (form with data), an error appears: The view spot.views.SpotDetailView didn't return an HttpResponse object. It returned None instead.

Django admin template: what is base_site.html
I am currently customizing the admin templates and this makes me wonders that what is the usage/purpose of base_site.html? I understand that base_site.html extends from base.html but from the original code itself, it only adds HTML content for branding and title blocks. Hence, if I'm overriding the whole base.html, I can just add HTML content for branding and title blocks in base.html and empty the base_site.html. Please correct me if I am wrong. Thank you -

Django-python email form is not forwarding sender's email address via gmail smtp
I am setting email form at my django-python based webpage. I have seen this cool video nicely explaining how setup django and how to incorporate gmail as the smtp server. The form has three fields: Full Name; Email Address; and Message. Everything works fine, but gmail smtp says that I (EMAIL_HOST_USER) am the sender of the message and not the person who fulfilled the form, i.e. I am missing fulfilled email address. From comments under the video, I have found I am not the only one who has this problem and who do not know how to solve it. I have managed only one temporal non-ideal solution to redirect everything from the form (i.e. variables message_name, message_email and message) into the body of the message as follows: send_mail( 'message from ' + message_name, # email_subject 'Full Name: ' + message_name + '; Email Address: ' + message_email + '; Message: ' + message, # message message_email, # from email ['recepient1@example.com', 'recepient2@example.com'], # To Email ) Does somebody know another more elegant solution which would redirect the email address as the real email's sender? Or minimally, please, give me an advice how to print Full Name; Email Address; and Message at … -

My question is how to read data from RabbitMQ (basic_consume) and send it to web client using websocket. I the websocket connet method I call the consume method to start consuming from rabbitMQ: async def connect(self): await self.accept() await self.channel_layer.group_add("gossip", self.channel_name) obj_rabbit_mq = RabbitMQueue() obj_rabbit_mq.consume("my_channel") and this is the consummer part. I can see the body part in my logs but the part that group_send it doesnt work. class RabbitMQueue: def consume(self, queue): print("Consuming {} ...".format(queue)) self.declare_queue(queue) def callback(ch, method, properties, body): print(" Received {}".format(body)) channels_layer = get_channel_layer() print("channels_layer: {}".format(channels_layer)) # async_to_sync(channels_layer.group_send)( channels_layer.group_send( "gossip", { "type": "user.gossip", "event": "New User", "username": body } ) self.channel.basic_consume( queue=queue, on_message_callback=callback, auto_ack=False) print(' [*] Waiting for messages. To exit press CTRL+C') self.channel.start_consuming() -
