I have a model Like this, which I got after doing a inspectdb
class Project(models.Model):
id = models.IntegerField(primary_key=True)
name = models.CharField(max_length=150, blank=True)
description = models.TextField(blank=True)
domainname = models.CharField(max_length=240)
show_description_in_overview = models.BooleanField()
completed_on = models.DateTimeField(blank = True, null = True)
completed_by_id = models.ForeignKey(User, db_column =
"completed_by_id", related_name = 'project_completed_by')
created_on = models.DateTimeField()
created_by_id = models.ForeignKey(User, db_column =
"created_by_id", related_name = 'project_created_by')
updated_on = models.DateTimeField()
updated_by_id = models.ForeignKey(User, db_column =
"updated_by_id", related_name = 'project_updated_by')
companies = models.ManyToManyField(Company, db_table =
'ac_project_companies')
users = models.ManyToManyField(User, db_table =
'ac_project_users')
I am getting this error
ValueError at /projects/add/
'Project' instance needs to have a primary key value before a many-to-
many relationship can be used.
I have a view like this
def add_projects(request):
from p2m.projects.forms import projectForm
if request.POST:
form = projectForm(request.POST)
print " valid" + str(form.is_valid())
if form.is_valid:
format = '%Y-%m-%d %H:%M'
current_date = datetime.now().strftime( format )
name = form.cleaned_data['title']
description = form.cleaned_data['description']
domainname = ""
show_description_in_overview = True
completed_on = current_date
completed_by_id = request.user
created_on = current_date
created_by_id = request.user
updated_on = current_date
updated_by_id = request.user
companies = request.user.get_profile().company_id
users = request.user
from p2m.projects.models import Project
p=Project(name = name,
description = description,
domainname = domainname,
show_description_in_overview =
show_description_in_overview,
completed_on = completed_on,
completed_by_id = completed_by_id,
created_on = created_on,
created_by_id = created_by_id,
updated_on = updated_on,
updated_by_id = updated_by_id,
)
p.save()
print p.id
p.companies.add(request.user.get_profile().company_id)
p.users.add(request.user)
isSaved = True
else:
form = projectForm()
return render_to_response('projects/new_projects.html', locals(),
context_instance=RequestContext(request))
