How to access Queryset returned to template by AJAX response - Django

Django cronjob not running
I am trying to create a cronjob from a custom Django command. When I run the command manually, it works perfect. Exactly what I want. The only thing is, that I want it scheduled (twice a day).

Crontab -e: # Edit this file to introduce tasks to be run by cron. # # Each task to run has to be defined through a single line # indicating with different fields when the task will be run # and what command to run for the task # # To define the time you can provide concrete values for # minute (m), hour (h), day of month (dom), month (mon), # and day of week (dow) or use '*' in these fields (for 'any'). # # Notice that tasks will be started based on the cron's system # daemon's notion of time and timezones. # # Output of the crontab jobs (including errors) is sent through # email to the user the crontab file belongs to (unless redirected). # # For example, you can run a backup of all your user accounts # at 5 a.m … -

Wagtail "prefetch" image urls for multiple pages
My page contains links to multiple Wagtail pages. The pages come from a query which looks something like this: SubPage.objects.in_site(site).live() Now, each page can have an image, so I'm presenting them in the template: {% for page in pages %} {% if page.header_image %} <div class="text-center"> {% image page.header_image width-400 class="img-fluid" %} </div> {% endif %} <h3> <a href="{{page.url}}"> {{ page.title }} </a> </h3> {% endfor %} The image rendering results, however, in a separate SQL query per page! Is there a way to sort of prefetch these image URLs in one query, best in a join with the original page query? Or generate them without SQL? The whole page is presumably dynamic, so caching alone isn't the answer. -

Request to Django project fails due to no referer, whats the best way round it?
When I send requests to my API django project, I get a 403 stating "CSRF failed, referee checking failed - no referer". the only way to fix this I've found is setting the Referer header on the request. but should I have to do this? should the referer not be taken from the url? I should add that i have two apps that call this api with POST requests- one works fine without setting the header explicitly, the other doesnt. I have DRF and corsheaders installed. -
