Celery worker connection with Rabittmq met broken pipe error IN Gevent Mode
This does not happen with our dev environment, tasks there run on a much smaller db, so issuing much less db queries and external requests, I imagine this issue might have something to do with task loads. error: Traceback (most recent call last): File "/usr/local/lib/python3.8/site-packages/celery/worker/consumer/consumer.py", line 246, in perform_pending_operations self._pending_operations.pop()() File "/usr/local/lib/python3.8/site-packages/vine/promises.py", line 160, in __call__ return self.throw() File "/usr/local/lib/python3.8/site-packages/vine/promises.py", line 157, in __call__ retval = fun(*final_args, **final_kwargs) File "/usr/local/lib/python3.8/site-packages/kombu/message.py", line 128, in ack_log_error self.ack(multiple=multiple) File "/usr/local/lib/python3.8/site-packages/kombu/message.py", line 123, in ack self.channel.basic_ack(self.delivery_tag, multiple=multiple) File "/usr/local/lib/python3.8/site-packages/amqp/channel.py", line 1407, in basic_ack return self.send_method( File "/usr/local/lib/python3.8/site-packages/amqp/abstract_channel.py", line 70, in send_method conn.frame_writer(1, self.channel_id, sig, args, content) File "/usr/local/lib/python3.8/site-packages/amqp/method_framing.py", line 186, in write_frame write(buffer_store.view[:offset]) File "/usr/local/lib/python3.8/site-packages/amqp/transport.py", line 347, in write self._write(s) File "/usr/local/lib/python3.8/site-packages/gevent/_socketcommon.py", line 699, in sendall return _sendall(self, data_memory, flags) File "/usr/local/lib/python3.8/site-packages/gevent/_socketcommon.py", line 409, in _sendall timeleft = __send_chunk(socket, chunk, flags, timeleft, end) File "/usr/local/lib/python3.8/site-packages/gevent/_socketcommon.py", line 338, in __send_chunk data_sent += socket.send(chunk, flags) File "/usr/local/lib/python3.8/site-packages/gevent/_socketcommon.py", line 722, in send return self._sock.send(data, flags) BrokenPipeError: [Errno 32] Broken pipe This is my celery command: celery -A analytics worker -P gevent -c 500 -l info -E --without-gossip --without-mingle --without-heartbeat & and my Django configs: CELERY_IGNORE_RESULT = True CELERY_WORKER_PREFETCH_MULTIPLIER = 100 CELERY_WORKER_MAX_TASKS_PER_CHILD = 400 CELERYD_TASK_SOFT_TIME_LIMIT = 60 * … -

Product Pop-up using Reach and Django
I am working through a tutorial on React and creating an ecommerce store with a Django backend. I am new to React. I have been able to get the React "FrontEnd" home page to display the products from the Django "products.py" which is a simple JSON file stored in the Django file system using the React Axios library. There is a product pop-up which displays the product information when the use clicks on the view button. I can't work out how to direct the pop-up to the "products.py" file. It is still drawing its information from the products.js in the React "FrontEnd" file system. The code is below. Any assistance would be appreciated. The code for the product page is below.

Why is Django database save not permanently saving the update?
I am using a postgresql database. I am updating a certain field of an existing database row and saving it again. However, this is change not reflecting inside the database (viewing it on DBeaver). The bizarre thing is that the change is properly reflected using the debugger and querying the database with the same ID. p_details: ProjectDetails = ProjectDetails.objects.get(pk=res['id']) p_details.build_status = ProjectBuildEnums.PASSED.value if res['error'] is None else ProjectBuildEnums.FAILED.value p_details.build_error = json.dumps(res) p_details.save(update_fields=["build_status", "build_error"]) sleep(1) new_p = ProjectDetails.objects.get(pk=res['id']) This is the line of code where I am updating the database. After the save, I am requerying the database using the same primary key ID. At this instance, using the debugger, I can see the changes clearly. However, viewing this database using DBeaver after refreshing the database doesnt show this change yet. Once the view is complete, and I refresh the database again, this change is still not present, meaning the update has disappeared. Does anyone know what is going on? After the above lines, the ProjectDetails database is no longer being touched. No errors are shown in the terminal/debugger either. -
How can I automatically update two objects in same model after 7 days continuously on Django?
I have a 2 models that I wish to interact/update every 7 days without needing me to execute. ( wether the website is online or offline )( local hosting for now ) class Model: name = model... quantity = models.IntegerField(default=0) obj A name = A quantity = 0 obj B name = B quantity = 1,000,000 I'm trying to find a way to transfer 1000 from obj B to obj A, every 7 days. I am looking but still can't find an answer that simplifies this situation. Thanks for the help! I haven't tried anything yet since I do not know where to start. I know how to update objects manually, on page load or with signals. it may have something to do with DateTime but I am not sure. Currently, there is no date field in the model. Or celery, but I have never used it before. -
