Hi!
When I try to test a post to a form that have a ModelChoiceField form
I get always a form error in that field "Select a valid choice".
The form is this:
class OperacionForm(forms.Form):
ticker = forms.ModelChoiceField(Valor.objects.all())
fecha = forms.DateField(widget=SelectDateWidget(years =
range(1950,2010)))
cantidad = forms.CharField()
precio = forms.CharField()
comision = forms.CharField()
tipo =
forms.ChoiceField(choices=[('Compra','Compra'),('Venta','Venta')])
And the test is this:
def testOperacionValida(self):
self.client.login(username='pepe', password='test')
usuario = User.objects.get(username='pepe')
response = self.client.post('/carteras/', {
'cartera_nombre':'micartera',
'submit':'Crear'
})
carteras = Cartera.objects.filter(nombre='micartera') &
Cartera.objects.filter(usuarioID=usuario)
count_before =
Operacion.objects.filter(carteraID=carteras[0]).count()
response = self.client.get('/carteras/nueva_operacion/%d' %
carteras[0].id)
response = self.client.post('/carteras/nueva_operacion/', {
'ticker':Valor.objects.all()[0],
'cantidad':'100',
'precio':'5',
'fecha':'06/07/2008',
'comision':'9',
'tipo':'Compra',
'submit':'Crear'
})
count_after =
Operacion.objects.filter(carteraID=carteras[0]).count()
self.assertEqual(count_after, count_before + 1)
The test fails with this message:
<ul class="errorlist"><li>ticker<ul class="errorlist"><li>Select a
valid choice. That choice is not one of the available
choices.</li></ul></li></ul>

FAIL: testOperacionValida (bolsacarteras.Carteras.tests.CrearOperacion)
----------------------------------------------------------------------
Traceback (most recent call last):
File "/home/fcano/djcode/bolsacarteras/../bolsacarteras/Carteras/tests.py",
line 92, in testOperacionValida
self.assertEqual(count_after, count_before + 1)
AssertionError: 0 != 1
----------------------------------------------------------------------
I print the form error before the assertion to see what is happening
with the form and I see the error. The problem is with the ticker that
I try to introduce like this:
'ticker':Valor.objects.all()[0],
I print Valor.objects.all()[0] and I see that the fixture is imported
correctly. How I can introduce this value in the test?
