QUESTION
I'm facing a very strange error from few days now. I have a python2.7 project that was running smoothly but since few days its been throwing an error:
Process finished with exit code 134 (interrupted by signal 6: SIGABRT)
I'm using virtual environment for my project. What happened was that few days ago I tried installing nginx using brew command and what I believe is brew updated some dependencies that were being used for python2.7 project (this is what i think might be the case). Now since that day, I'm facing this issue and I have googled it everywhere but couldn't resolve. Below is some information you might need to figure out.

Answered 2020-Nov-09 at 09:08Seems like your libraries are unsigned/old. Try this: https://dbaontap.com/2019/11/11/python-abort-trap-6-fix-after-catalina-update/

Does anyone have experience using ImageKit to manage thumbnails?
I currently have the following in my models.py:
...ANSWER
Answered 2020-Jul-29 at 03:33According to the docs:
ImageSpecFields, on the other hand, are virtual—they add no fields to your database and don’t require a database. This is handy for a lot of reasons, but it means that the path to the image file needs to be programmatically constructed based on the source image and the spec.
You might just want to stick to the ProcessedImageFIeld if you don't want your files to be stored in a cache folder.

Answered 2020-Apr-02 at 05:13Django-appconf version 1.0.4 only supports Django 1.11 and up and Python 3.5 and up. (https://github.com/django-compressor/django-appconf/blob/v1.0.4/setup.py). You need to downgrade to at least version 1.0.2 (supports Python 2.6+, doesn't say which django version: https://github.com/django-compressor/django-appconf/blob/v1.0.2/setup.py)
QUESTION
I'm currently trying to process an image using django-imagekit in my project. I'm quite new to the package, so I'm trying to implement a simple processor that converts the image to grayscale. I followed some samples from the docs.
I decided to use spec, which I've included in models.py. However, when I wanted to generate the image on a template, I came across the following error:
ANSWER
Answered 2020-Feb-21 at 07:14You need to pass the image file object to the template tag, not it's URL. You also need to pass it without {{ }} brackets and quotation marks:
QUESTION
I am developing a website/blog using Django and am in the middle of figuring out the proper setup/settings. I am running Ubuntu Server 16.04 in a virtual machine for testing. I am using what seems to be a common setup with Gunicorn and Nginx as well as PostgreSQL for the database and hosting the static and media files on Digital Ocean Spaces. I intend to host the site on Digital Ocean as well.
I have pieced together things from a few different guides here, here, here, and here.
I also use Django-Imagekit for handling images (url, resizing, etc) and manage everything in Django Admin.
The problem I am facing is that when I upload an image (either directly to an image form or via a post form) and save the object I end up getting a Server Error (500). If I refresh the page it then works fine. This also happens on the site itself (i.e. go to home page, server error, refresh, no error).
There are also absolutely no errors in my Gunicorn and Nginx logs.

...ANSWER
Answered 2018-Feb-16 at 05:41Seems that I managed to find a workaround. The issue is that django-storages was closing the image file after it was uploaded causing an I/O error in django-imagekit.
I found the workaround here.
QUESTION
Never worked with django-rq, redis. The problem should be solved easily, I think, but I do not know how.
When I start the server, I get this error ImportError: cannot import name get_failed_queue
I'm use Python 2.7
Full Traceback
...ANSWER
Answered 2019-Jun-13 at 03:05This happens because you use django-rq==2.0 that requires rq>=1.0. The function get_failed_queue() does not exist in rq==1.0 anymore, read the release notes to learn how to change your code to make it work again: https://github.com/rq/rq/releases/tag/v1.0
Otherwise, you can just downgrade to django-rq==1.3.1 and rq==0.13

Currently I'm trying to launch my django web app to GCP by following this doc: here
FYI: I'm using Django 1.9 and Python 2.7
After deploying the app using gcloud app deploy I checked my App Dashboard and saw these errors:
1) ImproperlyConfigured: Error loading psycopg2 module: No module named psycopg2

I just changed my app.yaml to this:
QUESTION
I'm using Django-imagekit to cut down image file sizes in my website since their current sizes are around hundreds.
Django-imagekit provides several ways, but I can't use the way done in
Django models because I already have about a thousand of images. They need me to upload images to get converted images with smaller sizes.
So, using the thumbnail template tag seems the only way for me right now. However, I'm confused about setting responsive sizes of images in the template tags.

Answered 2018-Jun-11 at 18:07You can achieve this by using jquery and bootstrap.

Install django-imagekit
You can use django-imagekit like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
