Django: How to add errors messages next to the form - django

Question

Currently I have a form, but somehow no matter how I register, I always fail. My implementation doesn't show what's wrong. Can someone figure out what's might happened?
Also, how can I add error messages next to each input box?
Below are my codes
{% block content%}
<div class="container">
<form class="form-signin" method="post" action="/sign_in/" role="form">
{% csrf_token %}
<h2 class="form-signin-heading">Please sign in</h2>
{% if error%} Your registration has not been successful. {%endif%}
<input type="username" class="form-control" name="username" placeholder="Username" required>
<input type="password" class="form-control" name="password" placeholder="Password" required>
<input type="password" class="form-control" name="password2" placeholder="Password" required>
<input type="username" class="form-control" name="name" placeholder="Name" required>
<input type="username" class="form-control" name="address" placeholder="Address" required>
<input type="username" class="form-control" name="Phone" placeholder="Phone Number" required>
<input type="email" class="form-control" name="emailAddress" placeholder="Email" required>
<input type="sinOrStNo" class="form-control" name="sinOrStNo" placeholder="Username" required>
<select class="form-control" name="type">
<option value="ST">Student</option>
<option value="FA">Faculty</option>
<option value="SF">Staff</option>
</select>
<button class="btn btn-lg btn-primary btn-block" type="submit">Sign in</button>
</form>
</div> <!-- /container -->
{% endblock %}
my views.py
error = False;
if request.method == 'POST':
borrower = BorrowerForm(request.POST)
if borrower.is_valid():
username = borrower.cleaned_data['username']
password = borrower.cleaned_data['password']
type = borrower.cleaned_data['type']
name = borrower.cleaned_data['name']
address = borrower.cleaned_data['address']
phone = borrower.cleaned_data['phone']
emailAddress = borrower.cleaned_data['emailAddress']
sinOrStNo = borrower.cleaned_data['sinOrStNo']
expiryDate = borrower.cleaned_data['expiryDate']
# add borrower accounts
user = User.objects.create_user(username, None, password)
user.set_password(password)
user.save()
user_type = UserProfile(username=username,type=0)
user_type.save()
# add borrower table
borrower_user = Borrower(username = username, password=password,name= name, address=address, phone=phone,emailAddress=emailAddress,sinOrStNo=sinOrStNo, expiryDate=expiryDate, type=type)
borrower_user.save()
else:
error = True;
else:
borrower = BorrowerForm()
return render(request, 'books/clerk/add_borrower.html', {'logged_in':logged_in, 'username':username, 'type':type, 'error':error, 'borrower':borrower})
My forms.py
class BorrowerForm(forms.Form):
username = forms.CharField(max_length=30)
password = forms.CharField(widget=forms.PasswordInput())
password2 = forms.CharField(widget=forms.PasswordInput())
name = forms.CharField(max_length=30)
address = forms.CharField(max_length=30)
phone = forms.CharField(max_length=30)
emailAddress = forms.CharField(widget=forms.EmailInput())
sinOrStNo = forms.CharField(max_length=10)
expiryDate = forms.DateField()
type = forms.CharField(max_length=3)
def clean_username(self):
existing = User.objects.filter(username__iexact=self.cleaned_data['username'])
if existing.exists():
raise forms.ValidationError(("A user with that username already exists."))
else:
return self.cleaned_data['username']
def clean(self):
if 'password' in self.cleaned_data and 'password2' in self.cleaned_data:
if self.cleaned_data['password'] != self.cleaned_data['password2']:
raise forms.ValidationError(("The two password fields didn't match."))
return self.cleaned_data

hm you use form and write all htmls in the html file why???
why don't you use
views.py
if request.method=='POST':
borrower = BorrowerForm(request.POST)
if borrower.is_valid():
......
return HttpResponseRedirect(<success url>)
else:
#here error messages it passed along with the form
return render(request, 'books/clerk/add_borrower.html',
{'borrower':borrower})
borrower = BorrowerForm()
return render(request, 'books/clerk/add_borrower.html',
{'logged_in':logged_in, 'username':username, 'type':type,
'error':error, 'borrower':borrower})
and use it the templates. that is what the purpose of forms.py. like :
<form class="form-signin" method="post" action="/sign_in/" role="form">
{% csrf_token %}
{{borrower.as_table}}
</form>
