Strange bug with form errors

[Nestor Burma]

I have a very strange bug with fom errors. On my development site, my code works fine. But on my production site (apache + mod-wgsi + posgresql), the form errors I defined in is_valid() method of my ModelForm (in a generic CreateView) are not product by the template. Have you already seen such a thing ?

 

Here is my code :

 

 

views.py:

class UserCreate(CreateView):
    model = User
    template_name = 'base/userCreate.html'
    success_url = '/utilisateurs/nouveau/success/{id}'
    form_class = UtilisateurCreateForm

 

forms.py:

class UtilisateurCreateForm(forms.ModelForm):
    class Meta:
        model = User
        fields = ['first_name', 'last_name', 'email']

    def is_valid(self):
        valid =  super().is_valid()
        if email != '' and User.objects.filter(email = email).exists():
            self.add_error('email', 'Il existe déjà un utilisateur avec cet email.')
            valid = False
        return valid

 

userCreate.html:

{% extends "base/base.html" %}

{% block contenu %}
<h3>Nouvel utilisateur :</h3>
<form action="" method="post">{% csrf_token %}
    {{ form.as_p }}
    <input type="submit" value="Enregistrer" />
</form>

{% endblock %}

 

Thank's for your help.
