Multiple buttons in html, same view, different values
I'm trying to have my html display a session.counter on an HTML page. The counter should increment by a random number, with 4 different options for the range at which it increments (based on buttons). So far, I have all their actions routing to the same view, but I'm not sure how to code the values into the view! Can I nest multiple if-checks into the view? If so, do I need to redirect immediately after each check, or can it be after the if-checks? Here's the views.py: def process_gold(request): reap = random.randrange(50,200) weave = random.randrange(35,50) summon = random.randrange(-200,200) war = random.randrange(-2000,2000) if request.method == 'POST': if goldCount not in request.session: goldCount = 0 ##will be displayed on HTML as the counter request.POST['reap'] = reap request.POST['weave'] = weave request.POST['summon'] = summon request.POST['war'] = war if reap in request.POST: goldCount += reap if weave in request.POST: goldCount += weave if summon in request.POST: goldCount += summon if war in request.POST: goldCount += war return redirect('/') Here's my html: <div id="goldCount"> </div> <div id="goldNode"> <h2>Blood Lotus Master</h2> <h3>It is said that when the blood lotus blooms, the night itself holds its breath.

How can all groups and users of that particular group have seperate data from database in django?
Let suppose there is a list of books on our database, each group (will have 3 to 4 users) can view that list and then a user can select any book, so after selecting, that book should only appear in that "user's selected list". That book should not appear in the all books list of the group again means no other user of that particular group can select the same book, nor user can deselect it. The actual database should not be effected. This is an example but I have to implement this functionality in my website. -

Accessing distinct foreign key relationships with django queryset
Given basic book/author models: class Book(models.Model): title = models.CharField(max_length=200) author = models.ForeignKey('Author') publisher = models.ForeignKey('Publisher') class Author(models.Model): first_name = models.CharField(max_length=100) last_name = models.CharField(max_length=100) Lets say I have a very complex query to select books based on a bunch of parameters (my actual models are much more complex than these). For simplification sake, my complex query for this example will just select books that have the word "the" in their title: q = Book.objects.filter(title__icontains="the") Is there a way (other than looping, or using reverse foreign key lookups) to get all distinct Author objects linked to the books in this query? E.g. I have tried adding: q = q.values('author').distinct() But this simply returns the author__id values. I am trying to go about it this way, as my 'complex query' is quite time/resource intensive, and I'd only like to run that query once (to get the books, and separate a list of distinct authors). Also the data sets need to be flattened (a separate list of Books and Authors) as it is getting presented via django rest framework, and my clients require the data sets to be flat. E.g.: { "books": [ {"id": 1, "title": "The Book.", "author": 1, "publisher": 1}, {"id": 2, … -

How can I use a single gmail address in a MTA (Mail Transfer Application)?
I would like to allow users to send automated emails from a dedicated email address (automated_alerts@my-domain.com). However, in the scripts, I don't want to give users access to the credentials.json so that they can modify the scope. I don't want to use a service that I need to pay for such as Amazon SES. I have looked into resources at the following links below, but I want users to simply specify an html body, any attachments, and the recipients and then forward this on to the MTA. If a user leaves the company, the automated emails should not fail when the user's email gets closed out. The script would just need to get moved to a different server's cron or whatever. Is there an easy way to do this? I am happy to use Django also, but would prefer to avoid using SES and having to pay to send internal company emails: https://docs.djangoproject.com/en/2.0/topics/email/ https://github.com/django-ses/django-ses https://developers.google.com/gmail/api/auth/scopes -
