So im trying at add a simple validator that checks against a postcode and returns a validation error if the user inputs non alphanumberics. But after trying i cant seem to get even the most basic validation message to show up.
Here is my form i used the example field validation just to try get it to show up but it doesn't
class CartAddShippingDetailsForm(forms.Form):
first_name = forms.CharField(max_length=100)
last_Name = forms.CharField(max_length=100)
email = forms.EmailField()
address1 = forms.CharField(max_length=100)
town = forms.CharField(max_length=100)
postcode = forms.CharField()
country = LazyTypedChoiceField(choices=countries)
additional_note = forms.CharField(max_length=100, required=False)
def clean_postcode(self):
data = self.cleaned_data['postcode']
if "fred@example.com" not in data:
raise forms.ValidationError("You have forgotten about Fred!")
else:
return postcode
This my views.py
def shipping_details(request):
cart = Cart(request)
shipping_form = CartAddShippingDetailsForm()
if request.method == 'POST':
shipping_form = CartAddShippingDetailsForm(request.POST)
if shipping_form.is_valid():
return redirect(reverse('test_order'))
else:
return render(request, 'shippingdetails.html', {'cart': cart, 'shipping_form': shipping_form})
and the html
{% extends "base.html" %}
{% load static %}
{% block title %}Shipping{% endblock %}
{% block content %}
<form action="{% url 'test_order' %}" method="post">
<div class="colcontainer">
{% csrf_token %}
{{ shipping_form }}
<input type="submit" name="Submit">
</div>
</form>
{% endblock %}
i have also tried using the validator because i just want to check that the field contains only alphanumeric symbols
postcode = forms.CharField(validators=[validators.validate_slug])
but nothing shows up at all, the forms passes validation and redirects sucessfully. I have tried everything and nothing seems to work. Do i need extra html code to show the validation errors? i cant find anything about it in the documentation and its driving me crazy!
