Django Model inheritance and foreignkeys
Hi, I have the following models class Person(models.Model): name = models.CharField(max_length=100) class Employee(Person): job = model.Charfield(max_length=200) class PhoneNumber(models.Model): person = models.ForeignKey(Person) How do I access the PhoneNumbers associated with an employee if I have the employee id? Currently I am using phones = PhoneNumbers.objects.filter(person__id=employee.id) and it works only because I know that the employee.id and person.id are the same value, but I am sure this is the incorrect way to do it.

Re: Passing Parameter to form in inlineformset_factory
Thanks for the help.

Passing Parameter to form in inlineformset_factory
Hi, I have the following Form defined class MyForm(ModelForm) def __init__(self, readOnly=False, *args, **kwargs): if readOnly: Do stuff to make the inputs readonly MyForm works perfectly when I instantiate it in the view as a form form = MyForm(readOnly=True, instance=ModelA) but when I try to use it in the inlineformset_factory I get the error NoneType object is not callable. I know the problem id the way I am using the MyForm in the inline call because I get the same error if I do either of the following Formset = inlineformset_factory(ModelA, ModelB form=MyForm (readOnly=True)) Formset = inlineformset_factory(ModelA, ModelB form=MyForm()) but it works if I do Formset = inlineformset_factory(ModelA, ModelB form=MyForm) obviously the readOnly param defaults to False and my inputs are not changed. Does anyone know how I can pass the readOnly param to MyForm using the inlineformset_factory or how else I can achieve what I want?

Re: Dynamically add a line to an inlineformset
Well...I don't know what happened but I have put my loop back in and now it works. I cannot get the problem to reproduce. I must have had something out of place but I don't know what, but it works now which is what I need. So again thanks for your help.

Re: Dynamically add a line to an inlineformset
I believe it wa the last of your suggestions, I was wrinting out the fields of the main form individually and somehow they must of been overwriting the inlineforms fields. I removed the loop that was doing the main form and just used the form object and it worked. So i need to go back and look over the fields to see why it was being overwritten. Thanks very much for your help.

Re: Dynamically add a line to an inlineformset
Thank you for your help. I have managed to get the inlineforms to reproduce on my page, however when I submit the form the extra inlines are ignored. I have printed the formset when it hits the view and the new lines that I have added have no values in them, the values that I enter in are not being passed back by the request. Is this something that someone has seen before?

Dynamically add a line to an inlineformset
Does anyone know how to add a new line to anlineformset dynamically? I have a page that contains an inlineformset and I need to be able to click a button and add a new line which will then be saved when the form is submitted, is that possible?

How to use inlineformset with a manytomany relationship
Hi,
Is there a way to create an inlineformset for two models with
manytomany relationship. I have created:
class Person(models.Model):
name = models.CharField
phone= models.ManyToMany(Phone)
class Phone(models.Model):
PHONE_CHOICES(('H','Home'),('W",'Work'),('M','Mobile'))
phone= models.CharField(max_length=10)
phoneType = models.CharField(max_length=1,
choices=PHONE_CHOICES)
In my view I have
PhoneFormSet = inlineformset_factory(Person, Phone)
but when I access the view I get the following error
has no foreignkey to
Is there something I have missed or do I need to setup my models
differently?
Thanks
Andrew
