Hi all,
I have two models, a contact model:
class Contact(models.Model):
company = models.ForeignKey(Company)
first_name = models.CharField(max_length=200)
last_name = models.CharField(max_length=200)
title = models.CharField(max_length=200)
office_telephone = models.CharField(max_length=20)
dd_telephone = models.CharField(max_length=20)
mobile_telephone = models.CharField(max_length=20)
address_1 = models.CharField(max_length=200)
address_2 = models.CharField(max_length=200)
address_3 = models.CharField(max_length=200)
city_county = models.CharField(max_length=200)
post_code = models.CharField(max_length=8)
fax = models.CharField(max_length=20)
email_address = models.EmailField(max_length=75)
and an email model:
class Email(models.Model):
contacts = models.ManyToManyField(Contact)
date = models.DateTimeField(auto_now_add=True)
notes = models.CharField(max_length=20000)
I have a view that shows the contact data for a particular contact
record, and I am putting a link on there that allows the user to
attach an email record to that contact. I want the M2M field to be
initially set to the contact record they have come from:
def addcontactemail(request, contact_id):
contact_id = int(contact_id)
contact = Contact.objects.filter(id=contact_id)
contact = contact[0]
if request.method == 'POST':
f = EmailForm(request.POST)
if f.is_valid():
f.save()
return
HttpResponseRedirect('http://127.0.0.1:8000/contact/%d' %
contact_id)
else:
f = EmailForm(initial={'contacts': contact.id})
return render_to_response('addcontactemail.html', {'formset': f})
But I am getting "Caught an exception while rendering: 'long' object
is not iterable" thrown when the browser tries to render the form in
the addcontactemail.html template.
I can set other initial data, for example to the 'notes' CharField
fine. I guess my question boils down to: how do you set initial data
for a many-to-many field?
Any pointers much appreciated!
Thanks,
Tom
