I'm running a Django app with Celery 5.3.4. I'm using Redis as the broker. I want to configure the task_time_limit and task_time_soft_limit options, but I can't get them to take effect when running locally.

Django: Create form from items in model, where each item in the model has multiple associated questions
I want to ask users multiple questions for each of a list of items in a Django model. As an illustrative example: Suppose I'm collecting data on people's opinions of the Harry Potter films. I want to know if someone has a) watched one of the films, and b) what rating (out of 10) they give said film. Assume that my Django app contains 3 models: Films - to populate the list of films; Users - details on the person who has responded; Reponses - responses for each user. This contains three columns: UserID, FilmID, Rating. It is only populated when a user has given a score for a film (i.e., no blank ratings) The table below shows what kind of answer I'd want to receive: a check of whether they watched the film, and their rating out of 10. Film Watched? Rating HP-1 Y 8 HP-2 Y 9 HP-3 N - HP-4 N - HP-5 N - HP-6 Y 7 HP-7 N - HP-8 N - The HTML of the form would have a similar layout: film name, check box for if it has been watched, and the rating field (dropdown or integer field). This would then load the … -
Can my heroku app store images even after restarting dyno
I have 2 services, backend api on django and frontend on react. My goal is to make django admin page create new food models with pasting new image. On local host everything works fine,images are saving on media/food_images and even after restarting local host they stay there. But when I host them on heroku, make few food models and then restart dyno images dissapear. I checked that when I make new food models in "heroku run bash" there is no media folder. Is there a way to save them for ever? -

Django backend with celery workers - memory threshold
I have a system with some periodic tasks. Each periodic task reads in files and creates objects out of them in the RAM. To prevent data loss, the cached file content is immediately stored from the peridoic task into the database after creating the object out of it. Then the file is deleted from the source. The object is queued into a RabbitMQ and the Celery workers take them for further processing and concurrency. Before caching the next file, the memory usage of the system is fetched with psutil. If it exceeds a threshld, the periodic task stops to read in files and continues with it, when executed the next time. My question is If this is generally a feasible approach if no data must be lost (the files are either stored in the database or still in the source folder) If it is a good approach to keep the synchronisation effort low (files are deleted after reading, the worker operates on objects and does not delete files and there is no sync needed with the periodic task) Which memory threshold is "safe" and fast enough. The file size can be up to 40 MB. -

Best way to update multiple templates based on form submission?
I'm working on a project that does several calculations based on user input, and I am now trying to create a new form in my variables_input template where the user can retrieve the values used in prior runs, and this works on the variables_input template resulting with the values being displayed on the page. However when the user goes to another page the values displayed are the most recently run calculations. How do I make it so when the user chooses a past run that they don't have to run the calculations but just get the values from the appropriate models to be displayed on the appropriate page? I was wondering if signals could achieve the desired result or if a simpler solution is possible. Below is an example of my project's code. variables_input.html {% block content %} <form action="" method="post"> {% csrf_token %} {{ form.as_p }} <input type="submit" , value="Submit" name="prior_run"> </form> <form action="" method="post"> <h2>Variables Table One</h2> {% csrf_token %} <!-- Table Columns --> <table> <table class="vartable" style="text-align: center;"> <colgroup> <col class="grey"> </colgroup> <thead> <tr> <th>Variable 1</th> <th>Variable 2</th> <th>Variable 3</th> <th>Variable 4</th> <th>Run Name</th> <th></th> </tr> </thead> <tbody> <tr> <div> <td><input type="text" value="{{inputs_list.0}}" name="var_one"></td> <td><input type="text" value="{{inputs_list.1}}" … -

I have django app that is connected to MySql database. I have renamed the field in models.py and succesfuly ran the migration.

Facing error on loading Ml Model through PipelineModel.load(model_location) in Django app
Hello I am using django application which has both asgi and wsgi modes. Now when I load the model in a standalone script it loads without any error but when I load it through an api call in django to perform task it gives an error: File "/mnt/d/InnovativeSolutions/DataAnalytics/DataAnalyticsDataTransformation/env2/lib/python3.10/site-packages/pyspark/ml/param/__init__.py", line 276, in <listcomp> src_name_attrs = [(x, getattr(cls, x)) for x in dir(cls)] AttributeError: __provides__ Code: from pyspark.ml import PipelineModel pipeline_model: PipelineModel = await PipelineModel.load(model_location) I have tried making the root method that is loading the ml model into an asynchronous type but still facing the same error. The standalone script loads the model without any error.
