Hi dudes,
Here is an update on this:
Workarround: I removed floppyforms on my Project and use Select2 instead
because it supports searches on foreignkey field and also create an
instance with a form easily.
Template
<script>
$(document).ready(function() {
$('#id_medicamento').select2();
});</script>
forms.py
class StockmovForm(forms.ModelForm):class Meta:model = Stockmov
fields = ['medicamento', 'motivo', 'Cantidad' ]
widgets = {'medicamento': forms.Select(attrs={'class':'form-control',
'placeholder':'Medicamento'}),'motivo':
forms.TextInput(attrs={'class':'form-control',
'placeholder':'Motivo'}),'Cantidad':
forms.NumberInput(attrs={'class':'form-control',
'placeholder':'Cantidad'}),
}
labels = {
'medicamento':'Medicamento', 'motivo':'Motivo del Movimiento',
'Cantidad':'Cantidad del Movimiento',
}
cya!
