Django custom Auth form. How to show error messages - django

Question

Another Django form question -.-
So, I have this form which works just fine, but it won't show any error messages. I'm pretty new to customising forms, so my question is that, do I need to specify anything else in order for my messages to show up?
Forms.py file
class UserLoginForm(AuthenticationForm):
error_css_class = "error"
def __init__(self,*args,**kwargs):
super(UserLoginForm, self).__init__(*args,**kwargs)
username = forms.CharField(widget=forms.TextInput(
attrs={'class': 'input','placeholder': 'Username','label':''}
))
password = forms.CharField(widget=forms.PasswordInput(
attrs={'class': 'input','placeholder': 'Password','label':''}
))
HTML File:
{%block content%}
<form class="form" method="POST">
{% csrf_token %}
<fieldset class="form-group text-center text-uppercase">
<h1 class="sign-in__header">Sign up</h1>
{% for field in form %}
<p>
{{ field }}
{{ field.help_text }}
</p>
{% endfor %}
</fieldset>
<div class="form-group">
<button class="submit" type="submit">Sign in</button>
</div>
{% for field in form %}
<div>{{ field.errors}}</div>
{% endfor %}
</div>
</form>
</div>
{%endblock content%}

Answer 1

If you remain on the same view when the form is not valid then in template you can access this errors by passing them to your view like this .
def View(request):
form = myForm(request.POST)
if form.is_valid():
return HttpResponseRedirect('/yourview/')
return render(request, 'template.html', {'form': form})
then in template
{% if form.errors %}
{% for field in form %}
{% for error in field.errors %}
<div class="alert alert-danger">
<strong>{{ error|escape }}</strong>
</div>
{% endfor %}
{% endfor %}
{% for error in form.non_field_errors %}
<div class="alert alert-danger">
<strong>{{ error|escape }}</strong>
</div>
{% endfor %}
{% endif %}

Answer 2

Try this:
{% if form.errors %}
{% for field in form %}
{% for error in field.errors %}
<p> {{ error }} </p>
{% endfor %}
{% endfor %}
{% endif %}
