How can I convert string into Form?
in model you can just use this line.
model = apps.get_model(app_label='app_label', model_name='str_model')
I have 3 forms namely:
and would like to do this.
type = "customer"
form = "Fund_"+type #that would make "Fund_customer"
form = apps.get_form(form) #I wonder if there's a function like this.
I just dont want to do if condition to achieve this.
Django doesn't have a registry of form classes like it does for models.
The simplest solution is to make a dictionary with forms keyed by name
forms = {
'customer': Fund_customer,
'employee': Fund_employee,
'supplier': Fund_supplier,
}
Then do a dictionary lookup to get the form class.
form_class = forms[form_type]
You need to remember to update the dictionary when you add a new form, but the advantage of this solution is that it is a lot simpler than creating a registry of form classes.
If all your forms are in the same forms.py module, you could try defining a function that uses getattr.
from myapp import forms
def get_form_class(form_type):
class_name = 'Fund_%s' % form_type
# third argument means it returns None by default instead of raising AttributeError
return getattr(forms, class_name, None)
modelform_factory function but I wasn't sure if this is what the OP was looking for
modelform_factory instead of defining the form classes. Be careful to validate the model name though!
