Django custon form with validate - django

Question

I have some problem with the form and Django.
I would like to do a custom (in column and with style) form from a model. But after few hours to try I thinks it's not possible.
So I decide to create not a forms.ModelForm but a forms.Form, in order to custom my form. But in this way i can't keep the validations...
And last thing I try, it in the template file to write a validation manually, it's work but when I submit my form with error, and when it's refresh, all the data are loose, and I see just the error message...
So it make me crazy... I just would like to do a nice form with django...
Thanks in advance
forms.py
class PatienceForm(forms.ModelForm):
class Meta:
model = Patience
fields = ('nom', 'prenom', 'age', 'email')
template.html
<form method="POST" accept-charset="utf-8">
{% csrf_token %}
<p><label for="id_nom">Nom :</label> <input type="text" name="nom" maxlength="200" required id="id_nom"></p>
<p><label for="id_prenom">Prenom :</label> <input type="text" name="prenom" maxlength="200" required id="id_prenom"></p>
<p><label for="id_age">Age :</label> <input type="number" name="age" required id="id_age"></p>
<p><label for="id_email">Email :</label> <input type="email" name="email" maxlength="254" required id="id_email"></p>
{% for err in form.email.errors %}
{{err}}
{% endfor %}
<button type="submit" class="save btn btn-default">Save</button>
view.py
def post_essaie(request):
if request.method == "POST":
form = PatienceForm(request.POST)
if form.is_valid():
logging.info('Hello')
post = form.save(commit=False)
post.published_date = timezone.now()
post.save()
return render(request, 'blog/succes.html')
return render(request, 'blog/teste.html', {'form': form})
else:
form = PatienceForm()
return render(request, 'blog/teste.html', {'form': form})
Thanks in advance for your help

Answer 1

for your form.py :
class PatienceForm(forms.Form):
nom = forms.CharField(max_length=200,label='Nom')
prenom = forms.CharField(max_length=200)
age = forms.integerField(max_length=200)
email = forms.EmailField(max_length=254)
# use clean to verify your form
def clean(self):
cleaned_data = super(ContactForm, self).clean()
nom = cleaned_data.get('nom')
prenom = cleaned_data.get('prenom')
age = cleaned_data.get('age')
email = cleaned_data.get('email')
if not name and not email and not message:
raise forms.ValidationError('le formulaire est vide')
in your views.py you can use :
from django.shortcuts import render
from .forms import ContactForm
def post_essaie(request):
if request.method == 'POST':
form = PatienceForm(request.POST)
if form.is_valid():
logging.info('Hello')
nom = form.cleaned_data['nom']
prenom = form.cleaned_data['prenom']
age = form.cleaned_data['age']
email = form.cleaned_data['email']
# here create your entry with all the data from your form then add
# your published_date
post = Patience(nom=nom, prenom=prenom, age=age,
email=email, published_date = timezone.now())
post.save()
return render(request, 'blog/succes.html')
else:
form = PatienceForm()
return render(request, 'blog/teste.html', {'form': form})
Voila Bonne journée !!
