Hi guys I'm learning django and I am doing some tests with CRUD using
crispy forms: I created a model and I can create and read data without any
problem.
I have problem in update. I get this error:
postalgps.models.Tabacchino.DoesNotExist: Tabacchino matching query does
not exist
*In model I have:*
class Tabacchino(models.Model):
nome = models.CharField(max_length=200)
cognome = models.CharField(max_length=200)
indirizzo = models.CharField(max_length=200)
telefono = models.CharField(max_length=30)
email= models.CharField(max_length=200)
nome_tabacchi = models.CharField(max_length=200)
attivo = models.BooleanField(blank=True) #esiste anche l'opzione null=True
pub_date = models.DateTimeField(auto_now_add=True)
*In views.py:*
def updateTabacchi(request):
query = request.POST.get('tabacchi_id')
tabacchi = Tabacchino.objects.get(id=query)
form = TabacchinoForm(instance=tabacchi)
if form.is_valid():
form.save()
return redirect('dashboardPage')
return render(request, 'tabacchino/admin/update_tabacchi_admin.html',
{'form': form, 'tabacchi': tabacchi })
*In urls.py: *
urlpatterns = [
....
path('updateTabacchi/', views.updateTabacchi, name='updateTabacchiPage'),
....
*in forms.py*
class TabacchinoForm(forms.ModelForm):
nome = forms.CharField(widget=forms.TextInput(attrs={'placeholder': 'xxx'}))
cognome = forms.CharField(widget=forms.TextInput(attrs={'placeholder':
'xxx'}))
indirizzo = forms.CharField(widget=forms.TextInput(attrs={'placeholder':
'xxx'}))
telefono = forms.CharField(widget=forms.TextInput(attrs={'placeholder':
'xxx'}))
email = forms.EmailField(widget=forms.TextInput(attrs={'placeholder':
'xxx'}))
nome_tabacchi =
forms.CharField(widget=forms.TextInput(attrs={'placeholder': 'xxx'}))
attivo = forms.BooleanField(required=False)
#pub_date = forms.DateTimeField(auto_now_add=True)
class Meta:
model = Tabacchino
#fields = "__all__"
fields = ['nome', 'cognome', 'indirizzo', 'telefono', 'email',
'nome_tabacchi', 'attivo']
*In the template:*
<form class="form-horizontal" role="form" method="POST">
{% csrf_token %}
{{ form}}
<div class="form-group last">
<div class="col-sm-offset-5 col-sm-9">
<button type="submit" class="btn btn-success btn-sm">
submit </button>
</div>
</div>
</form>
When I do submit from template I get:
postalgps.models.Tabacchino.DoesNotExist: Tabacchino matching query does not
exist.
where is the mistake?
Thanks in advance
