Heroku and AWS, Disappearing images
I have built a heroku app that basically stores photos that I upload. I have set up an AWS account with an s3 bucket and I have also set up my IAM user for full access. When I upload my images via the website, everything goes well and the images show in my bucket and on my albums, but I've just logged onto my website after around 24hrs and all the images I uploaded are gone and some are just not rendering. Now I know that this would happen if I was trying to store them on Heroku, but does anyone have any ideas why they're disappearing whilst I'm using AWS for storage? TYIA EDIT When I click on the images that are not rending to open in a new tab i get the following error. I removed some of the data just incase its private.

How can I get rid of the ModuleNotFoundError: No module named <modulename> error?
I'm getting ModuleNotFoundError: No module named 'bookList' when trying to run the bot I wrote. In the bkmBooks.py file, I imported my model " from bookList.models import BookList " in this way. However, after the migrate, the functions inside my bkmBooks.py file did not work. What might be causing this error?

Can Elasticsearch be used as a database in a Django Project?
Can we directly use Elasticsearch as a primary database in Django? I have tried finding the solution or a way out but could not find any relevant information. Everywhere it is said that we can use Elasticsearch as a search engine over any other primary database. But as per my understanding Elasticsearch is a NoSQL Database, so there should be a way to use it as a Primary Database in a Django Project. Please help, if someone has any idea about it. -

When I pass a url parameter to modelform, None is passed instead of the url parameter
I am trying to build up a posting webpage. This is how it works: you click a button, the posting form will appear, you fill in the form, you click the submit button, and the process is complete.

How to simplify phone_number field update Process in django including verification
Problem Description: We have a User model where Phone number is been set as username and its unique=True, We also have a field where to represent verified/unverified users. And we verify users by OTP verification to phone number. So now we need to add a new feature where user can replace his phone_number and then he will go to verification process and then we will change his number. And also We need to preserve his previous number (which he already verified) until this new number is verified. If for some reason user decides to go back without verification we delete newly added number and keeps his old number as username. So what would be the best way to approach this problem What I'm considering to have another Model linked with ForeignKey to User class AlternativeNumber(models.Model): user = User() # forignkey number = Charfield is_verfied = BooleanField So we will be verifying users number and replacing his original number from his alternativenumber_set Do you think we can simply it more. Do you think it might have some flaws or we go with a better appraoch ? thanks. -
Print several separate tables from one HTML document
I did the work and was able to render the data into tables. Now I have the following structure on the page: <div class="report-table-container mt-5" id="**current_pko_table**"> *some data* </div> <div class="report-table-container mt-5" id="**current_report_table**"> *some data* </div> <div class="report-table-container mt-5" id="**current_refund_to_customers_table**"> *some data* </div> Can anyone suggest a solution to make the "print all" button so that it only prints: current_pko_table, current_refund_to_customers_table, current_refund_to_customers_table? And also offer to separate the pages for printing, so that each of these documents is on a separate page when printed. I will be glad for any help. My whole project is built on django, but my experience with JS small. I will be glad for any help! -

Failed to Fetch when the request didn't fail and code seemingly executes fine
I am using elasticsearch-dsl to construct 2 complex queries and execute them over multiple indices at the same time with MultiSearch. It is working fine in 99% of cases but rarely fails for some input parameters with such an error printed on backend (Django): 2022-09-29 03:37:23,592 ERROR: https://aws_instance_name.us-east-1.es.amazonaws.com:443 For such input params it never is executed successfully, so its definitely dependent upon the inputs. The backend Django python code executes fine until the response is actually returned which I observe with logger.info statements, but the error is there. When I set the response to an empty one to exclude issues further down the line with the specificity of the response, it still fails, so it's as if it's not the issue of the response. I executed both queries separately (on backend they are executed together in one with MultiSearch, so it could potentially be some issue inside the MultiSearch itself) over the very same indices in AWS Kibana and both are returning results fine in a matter of a couple of seconds. I wonder if there is a way to print out detailed info about the issue and not just ERROR:aws_instance message that is useless. What else could go wrong … -

How To Convert Free Heroku Django To Paid App
Some time ago I created my first training Python Django Web application on Heroku because I could do it for free. It is a typical CRUD application with a persistent database. I have enjoyed showing it to others since then. I just received notice from Heroku that I need to convert it to a paid application. I having indeed spent hours pouring over the documentation cited about the conversion, but I am still confused about what exactly I need to do. I believe that the best path is to change the dyno status from "free" to "eco". That would cost only $5 a month. I am not sure about the database. Is that included, or would that need also to be converted to a paid "mini" postgres for an additional $5 a month? And would I have to do all the data conversion work manually, or does that happen automatically behind the scenes? Answers to these questions are key to understand if Heroku will still be a home for my application, or will I need to move it to another platform. Thank you. -
When I include a hidden field in my modelform, the modelform is not submitted
I am trying to build up a posting webpage. This is how it works: you click a button, the posting form will appear, you fill in the form, you click the submit button, and the process is complete. And when the form is submitted, a url parameter will be passed as the value of a hidden input in the modelform in the views.py.

Get seperate task id in celery chain in Django
I am running a scraper in background using celery chain. I have 2 task that should run in a synchronous manner. result = chain(taskOne.si(data= data), taskTwo(data = data)).delay() This code works,as i can see the return data in the terminal.

How to return calculations to a template for all objects in a class model in Django
I am trying to build a simple form which calculates which machine would run a film width the quickest, the parameters and capabilities of each machine are held in a django model. The width of the film and how much of it will be entered in the form and the quantity needed. The function should work out which machine(s) can run it, what the max speed is and the average speed over the machines that are capable. I want to return the values of the calculation and maybe run a for loop and display the values for each machine in a results.html template in a table. I also want to display average times across machines capable of running the widths of film. I had some success with lists but would like to use a class that I can use in the template and do away with the lists. Any help with this would be much appreciated as I am getting pretty lost in it! I have only started on the 'Layflat Tubing' function in the hope that I can get it right and just copy down to the other functions. from django.views.generic.base import TemplateView from django.shortcuts import render import math, … -
How do I invert in Django the pretty "yes", "no" icons of a BooleanField in the Admin site?
When your model has a BooleanField, the Django Admin site displays circular icons: a green checkmark for "True" a red X for "False" The Django docs call those icons "pretty": If the field is a BooleanField, Django will display a pretty “yes”, “no”, or “unknown” icon instead of True, False, or None. it looks great! but my BooleanField is called "pending" so if pending = True , I want Django Admin site to display a red X instead of a green checkmark. Because green means "good" and red means "bad". Most of my entries are not pending, so the list is full of red X icons, it looks bad, I want them to be mostly green checkmarks instead. I know I could add a def in the model with a return not self.pending but that displays the words "True" and "False" instead, I want the icons.
