How do I check my email is available in database or not

I wrote one model that is having email field. I added some emails to it by admin. What I need is when I type any email that should check with my database email if exist it should show email is already there:

models.py #in my database already some data is there

class Friend(models.Model):
    email = models.EmailField(max_length=100)

    def __str__(self):
        return self.email

forms.py

class FriendForm(forms.ModelForm):
    class Meta:
        model = Friend
        fields = ['email']

views.py

def check(request):
    form = FriendForm(request.POST or None)
    if form.is_valid():
        form = Friend.objects.filter(**form.cleaned_data)
    context = {
        'form': form
    }
    return render(request, "one.html", context)

I imported every thing. When I am trying this code it is directly rendering to one.html. What I need is it should check if email is there in database then only it should render.

class Friend(models.Model):
     email = models.EmailField(max_length=100,unique=True,error_messages={'error':'The Email already exists'})

you can change your model to this. 

if form.is_valid():
    form = Friend.objects.filter(**form.cleaned_data)
else:
    redirect('to_some_page')
