How to delete user in django?

Question

This may sounds a stupid question but I have difficulty deleting users in django using this view:

@staff_member_required 
def del_user(request, username):    
    try:
        u = User.objects.get(username = username)
        u.delete()
        messages.sucess(request, "The user is deleted")
    except:
      messages.error(request, "The user not found")    
    return render(request, 'front.html')

in urls.py I have

url(r'^del_user/(?P<username>[\w|\W.-]+)/$', 'profile.views.del_user'), 

Instead the user being deleted I get The user not found.

What can be wrong here?

Well you are goind into the except block, it is not a good idea use a generic except. You could try printing the error you're getting. – Zumstein

Remove the try and except to look for any errors. – Sapor

There's probably too little information here for us to help you, but one thing you might try is opening up a python console in your environment and manually run each step. I find that tends to illuminate a lot of issues. (just remember to do "from django import setup" and then "setup()" first if using Django 1.7+ – Sniper

Use try: yourcode... expect DoesNotExist: dosomething... instead. – Vicenta

You should change your code to:

@staff_member_required 
def del_user(request, username):    
    try:
        u = User.objects.get(username = username)
        u.delete()
        messages.success(request, "The user is deleted")            

    except User.DoesNotExist:
        messages.error(request, "User doesnot exist")    
        return render(request, 'front.html')

    except Exception as e: 
        return render(request, 'front.html',{'err':e.message})

    return render(request, 'front.html') 

and display the err in your template to see further error messages

I want a button for this, so when I click the button beside the User in a ListView of users, then it takes that users pk, so I can filter it. – Moia

Answer 2

@login_required
def del_user(request):
    user = request.user
    user.delete()
    redirect("login")

OP didn't want to delete the user enacting the request. – Zane
