how to retrieve latest data from django model in tamplates-CodePudding

i am trying to retrieve latest single data from Django model and show it in templates instead of all the data the method I trying to use in my view to achieve that

def preview(request):
    readme = Personal_readme.objects.latest('create_date')
    return render(request, 'preview.html',{'readme':readme})

and in my models

create_date = models.DateTimeField(default=timezone.now,editable=False)

but when I runserve and refer to a page it TypeError at /preview/ Personal_readme' object is not iterable it work fine when use this

readme = Personal_readme.objects.all()

but retrieve all the data in it but i want to retrieve single(one) the latest data based on create_date

I have no idea why its is show like this

CodePudding user response：

I guess your template waits list of items, and when you give it one, it cause to error. So you can change your template to handle 1 item, or give it list with 1 item like so:

def preview(request):
    readme = [Personal_readme.objects.latest('create_date')]
    return render(request, 'preview.html',{'readme': readme})
