Re: Send an object parameter from views.py to forms.py

I've moved to CBV sometime ago  and  I can not write  your code on fly:

 Let imagine:

1) User request page using "GET"

2) User set some values and send it using  "POST"

3) New page is shown using  new "GET"

id_medioedit is set ant stage 2 and answer at 3 is ok. But you dont know how to set  it at stage 1 . In this case  you need default value  for first get  

Add  some code for "GET" such as

if request.method == "GET":

    p = Medious.object.get(id=1)

Many thanks,

Serge

Hello,

I have a problem because I don't know how could I send one specific parameter. I've sent other parameters sometimes in others apps but this time is more difficult.

Below it's my code. I want to send 'p', which is an object. The problem is that I can't send it in else because I've defined p outside (if). So when I tried to send it, p is not defined. I can't define it outside because I need id_medioedit, which is an id obtained from template in medioedit_id form.

Anyone who knows how to solve this?

Thank you in advance

Views.py 

if 'medioedit_id' in request.POST:
        formularioeditarmedios = EditMediosForm(request.POST)
       
        try:
            id_medioedit = request.POST['medioedit_id']
            p = Medios.objects.get(pk=id_medioedit)
            mensaje = {"status":"True","medioedit_id":p.id}


            if formularioeditarmedios.is_valid():
               ...

else:
        formularioeditarmedios = EditMediosForm(p=p)

Forms.py

class EditMediosForm(forms.Form):
                          #initial='somevalue'
  titulo = forms.CharField(max_length=140, widget=forms.TextInput(attrs={'style': 'width:140px'}))

def __init__(self,p,*args,**kwargs):
    p = kwargs.pop("p", None)
    super(EditMediosForm, self).__init__(*args,**kwargs)
    self.fields['titulo'].initial = p.titulo
