I need to dynamically create a choice field in Django Form (not ModelForm) using the logged user as a parameter.
The view:
def cadastro(request):
medico = request.user.medico
usuario=request.user
clinicas = medicos.clinicas.all()
escolhas = tuple([(c.id, c.nome.clinica) for c in clinicas])
if request.method == 'POST':
formulario = NovoProcesso(escolhas, request.POST)
if formulario.is_valid():
formulario.save(usuario)
else:
formulario = NovoProcesso(escolhas)
contexto = {'formulario': formulario, 'clinicas': clinicas}
return render(request, 'processos/cadastro.html', contexto)
Form class:
class NovoProcesso(forms.Form):
def __init__(self, escolhas, *args, **kwargs):
super(NovoProcesso, self).__init__(escolhas, *args, **kwargs) -------> the source of the problem is here.
self.fields['clinicas'].choices = escolhas
clinicas = forms.ChoiceField(widget=forms.Select, choices=[])
# there are other fields here, but I ommited for the sake of clarity
def(save):
#custom save method....
I incorrectly passed arguments to the init method as described here: object has no attribute 'get'
I'm having trouble to understand the line: self.fields['clinicas'].choices = escolhas
Not sure if I should write self.fields['clinicas].choices or . widget.... not sure how to write de form field inside the class. Tried several variations.
I'm getting the following error:
Internal Server Error: /processos/cadastro/ Traceback (most recent call last): File "/home/lucas/dev/.virtualenvs/autocusto/lib/python3.8/site-packages/django/forms/forms.py", line 158, in getitem field = self.fields[name] KeyError: 'errors'

I've tried the following solutions with no success: Django: how to pass parameters to forms, Django Forms: pass parameter to form
Don't know what I'm missing!
