Hello,
I've done it !!! yooohooo.
But I think this is not the best way because it can be processor time
consuming if I've a lots of suscribers (Wich is not the case now).
Here is the code in forms.py:
class Step1Form(forms.Form):
email_adresse = forms.EmailField(max_length=255)
telephone = forms.CharField(max_length=14)
def clean(self):
"""
Test if email_adresse is already in the database
"""
if 'email_adresse' in self.cleaned_data :
l = []
for p in Customer.objects.all():
l.append(p.email_adresse)
if self.cleaned_data['email_adresse'] in l:
raise forms.ValidationError(u'Email already exist')
return self.cleaned_data
It works ....
I'll try with another method function:
p=Customer.objects.all()
try:
p.objects.filter(Customer__email_adresse__exact=
self.cleaned_data['email_adresse']
raise forms.ValidationError(u'Cette adresse Email est deja
utilisee')
return self.cleaned_data
except:
pass
If you have beter idea.
regards
Alain
Entry.objects.filter(blog__name__exact='Beatles Blog')
