Django Loop Through Objects After Bulk .update()
This code runs on cron. So I want to update the status of the objects immediately so that these objects don't get picked up again if a second cron starts before the current one finishes (which will eventually start to happen with my app.) # Grab all pending emails. emails = delivery_que.objects.filter(status='PENDING') emails.update(status='SENDING') # Loop through the pending emails. for email in emails: The current code doesn't work, as I seem to no longer have access to the objects after I .update() them. This is the workaround I implemented: # Grab all pending emails. emails = delivery_que.objects.filter(status='PENDING') emails.update(status='SENDING') emails = delivery_que.objects.filter(status='SENDING') # Loop through the pending emails. for email in emails: Is there another better solution I'm missing? I'd prefer not to query the database again to reselect the objects that I should already have access to from the first query. -

I can get the result I want in SQL console, but Django adds, all the related objects that belong to the StatusGroup. I have a misconception, but I don't know what that is. -

How to map URLs to views in django?

Django ORM multiple chained JOIN equivalent and aggregation

AJAX request returns HTML file instead of data. ( Django & Python )
I have a profile page with user posts. People can like/dislike the posts. It works well but it reloads the page, that is why I am implementing AJAX. The route goes like this. Inside the profile view is the "like POST" request ending with a data = { 'likes':post.likes.all().count() } return JsonResponse(data,safe=False)" When clicking on the like button, I can see the data on a blank page if I want to. So I know it is receiving it. Unfortunately, when using AJAX, instead of returning the data. it returns the profile view's return render(request, "profile.html", context) Here is my AJAX code const post_id = $(this).attr('id') const likeText = $( `.like_button${post_id} `).attr('name') const trim = $.trim(likeText) const url = $(this).attr('action') let res; const likes = $(`.like_count${post_id}`).text() || 0 const trimCount = parseInt(likes) $.ajax({ type: 'POST', url: url, data: { 'csrfmiddlewaretoken':$('input[name=csrfmiddlewaretoken]').val(), 'post_id':post_id, }, success: function(data){ console.log('success', data) }, error: function(data){ console.log('error', data) } }) Any help would be much appreciated. First time using AJAX, so as much details would be appreciated. -
