Re: Changemanipulator and follow true
Ok...I've gotten this working a different way, in case anyone is
interested, I thought I'd post it here (although parent_company is
currently not saving for some reason..anyone?)
Here is my model code...again..notice that the Company has a related
Address.
class Address(models.Model):
address_id = models.AutoField(primary_key=True)
street_number = models.IntegerField(null=True, blank=True)
street_name = models.CharField(blank=True, maxlength=135)
street_suffix = models.TextField(blank=True)
city = models.CharField(blank=True, maxlength=135)
county = models.CharField(blank=True, maxlength=135)
state = models.CharField(blank=True, maxlength=60)
country = models.CharField(blank=True, maxlength=135)
zip = models.CharField(blank=True, maxlength=30)
update_user = models.ForeignKey(UserInfo)
#models.IntegerField(null=True, blank=True)
time_stamp = models.DateTimeField()
class Meta:
db_table = 'address'
class Company(models.Model):
company_id = models.AutoField(primary_key=True)
parent_company = models.ForeignKey("self",unique=True,null=True)
address = models.ForeignKey(Address,unique=True
company_name = models.CharField(blank=True, maxlength=150)
company_description = models.CharField(blank=True, maxlength=300)
update_user =
models.ForeignKey(UserInfo)#models.IntegerField(null=True, blank=True)
time_stamp = models.DateTimeField()
def __str__(self):
return self.company_name
class Meta:
db_table = 'company'
Ok..now my view code..I've subclassed changemanipulator
class CustomCompanyChangeManipulator(Company.ChangeManipulator):
def __init__(self,company_id):
all_companies = Company.objects.all()
Company.ChangeManipulator.__init__(self,company_id)
self.original_object =
Company.objects.get(company_id=company_id)
allcomp = ()
if all_companies:
allcomp = [(obj.company_id, obj.company_name) for obj in
all_companies]
noneobj = ('','')
allcomp.insert(0,noneobj)
self.fields = (
forms.SelectField(field_name="parent_company_id",
is_required=False,choices=allcomp),
forms.TextField(field_name="company_name", length=20,
is_required=True),
forms.TextField(field_name="company_description",
maxlength=255, length=30,is_required=True),
forms.SelectField(field_name="street_prefix",
is_required=False,choices=STREET_PREFIX),
forms.IntegerField(field_name="street_number"),
forms.TextField(field_name="street_name", length=30,
maxlength=45),
forms.SelectField(field_name="street_type",
is_required=False,choices=STREET_TYPE),
forms.TextField(field_name="city", length=30,
maxlength=45),
forms.SelectField(field_name="state",
is_required=True,choices=STATES),
forms.TextField(field_name="zip",is_required=True),
forms.CheckboxField(field_name="createoffice",
is_required=False),
)
def flatten_data(self):
origcompany = self.original_object
fields = dict([(field.name, getattr(origcompany,
field.attname)) for field in self.original_object._meta.fields])
for field in origcompany.address._meta.fields:
fields[field.name] = getattr(origcompany.address,
field.attname)
return fields
def save(self, new_data):
origcompany = self.original_object
origcompany.company_name = new_data['company_name']
origcompany.company_description =
new_data['company_description']
origcompany.parent_company = new_data['parent_company_id']
origcompany.save()
origaddress = origcompany.address
origaddress.street_prefix = new_data['street_prefix']
origaddress.street_number = new_data['street_number']
origaddress.street_name = new_data['street_name']
origaddress.street_type = new_data['street_type']
origaddress.city = new_data['city']
origaddress.state = new_data['state']
origaddress.zip = new_data['zip']
Here is where I actually call the code to render the form...
def rendereditcompany(request,company_id):
current_user = request.session.get('CurrentUser')
if not current_user:
return HttpResponseRedirect('/rsswww/login')
nonfields = {'time_stamp': False,'address':True }
manipulator = CustomCompanyChangeManipulator(company_id)
company = manipulator.original_object
if request.POST:
# If data was POSTed, we're trying to create a new Place.
new_data = request.POST.copy()
# Check for errors.
errors = manipulator.get_validation_errors(new_data)
if not errors:
manipulator.do_html2python(new_data)
manipulator.save(new_data)
return HttpResponseRedirect('/rsswww/companyadmin')
else:
print "errors"
print manipulator.get_validation_errors(new_data)

Well, I think we'll have to wait the answer of some experienced django
user.

In that sample I moved the foreign key on the other model.

You've got a one-to-one relation (unique=True).
I suppose that using the Address ChangeManipulator could do the trick.

You can use Address ChangeManipulator and hide fields from other models
with the follow argument.

There's always a way !
Remember you can always code all by hand (like a lot of web-developer
usually do).
At the very beginning I was writing a lot of code to make the things
exactly like I wanted, but as time passed, I discovered that django
could do the same thing with less effort (and code).
And then... zac... dozens of lines of my code gone ! It's a great
pleasure. :-)

Re: Changemanipulator and follow true
Hi Massimiliano,
I hope you don't mind my emailing you directly... I sent a reply on the
groups... but thought I'd send it directly to you as well... since you seem
to be using this technique...
In my form I'm using the following ( I tried putting a 0 in there like your
sample..but it gave an unindexable object error )
Street #:{{
form.address.street_number }}
Now in my company definition I have:
class Company(models.Model):
company_id = models.AutoField(primary_key=True)
parent_company = models.ForeignKey("self",null=True,blank=True)
address =models.ForeignKey(Address,unique=True,edit_inline=models.TABULAR)
#models.IntegerField(null=True, blank=True)
company_name = models.CharField(blank=True, maxlength=150)
company_description = models.CharField(blank=True, maxlength=300)
update_user =models.ForeignKey(UserInfo)#models.IntegerField(null=True,
blank=True)
time_stamp = models.DateTimeField()
def __str__(self):
return self.company_name
class Meta:
db_table = 'company'
It isn't erroring out..so it seems to know what the address field is... but
doesn't show an edit box? Did I miss something that I should be doing..or
can I not do it with the comany change manipulator? I can't use the
address...because an address will be on a company object..as well as some
others I have..not just only on a Company object.
Thanks for any info,
Carole

Re: Changemanipulator and follow true
Hmm... I have to keep the Address on Company... as Address will be being used in other places as well..and is not always related to a company... I have a Property and User classes as well..and each of them will have an Address foreign key. I'd like to be able to show a form for Property and User editing as well..that also shows the address... So would it be form.Company.0.street_number if I wanted to access the address via the Company change manipulator? I am thinking that is not right... but maybe I just can't do this the way I'm wanting... --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Changemanipulator and follow true
I hope I understood your problem (as my english is ugly).
I have a similar application: note that I put the foreign key on
Address.
class Address(models.Model):
address_id = models.AutoField(primary_key=True)
# Here's the foreign key (note the edit_inline)
company = models.ForeignKey(Company, edit_inline=models.TABULAR)
status_id = models.IntegerField(null=True, blank=True)
...
class Company(models.Model):
company_id = models.AutoField(primary_key=True)
parent_company = models.ForeignKey("self",null=True,blank=True)
### address = models.ForeignKey(Address)
company_name = models.CharField(blank=True, maxlength=150)
...
I had no problem with ChangeManipulator (and with a custom manipulator
too). Moreover you don't need to specify the follow argument.
If you want to keep the foreign key on Company I suppose you must use
the Address ChangeManipulator and specify the edit_inline argument.
In the template you have to add a 0 (zero) to identify the first
address. If you want only one Address per Company you can make the
relation one to one adding unique=True to the company field.
Street #:{{
form.address.0.street_number }}
If you want more documentation, search edit_inline here
http://www.djangoproject.com/documentation/model_api/#relationships
Hope this helps you.

Changemanipulator and follow true
I was hoping someone could tell me if there is a way to do this... I
thought using follow and true...it should work..but have been
unsuccessful.
I have an address object that is tied to a company object:
class Address(models.Model):
address_id = models.AutoField(primary_key=True)
status_id = models.IntegerField(null=True, blank=True)
street_number = models.IntegerField(null=True, blank=True)
street_name = models.CharField(blank=True, maxlength=135)
street_suffix = models.TextField(blank=True)
unit_number = models.CharField(blank=True, maxlength=30)
city = models.CharField(blank=True, maxlength=135)
county = models.CharField(blank=True, maxlength=135)
state = models.CharField(blank=True, maxlength=60)
country = models.CharField(blank=True, maxlength=135)
zip = models.CharField(blank=True, maxlength=30)
full_address = models.CharField(blank=True, maxlength=765)
street_prefix = models.TextField(blank=True)
street_type = models.CharField(blank=True, maxlength=30)
update_user = models.ForeignKey(UserInfo)
#models.IntegerField(null=True, blank=True)
time_stamp = models.DateTimeField()
class Meta:
db_table = 'address'
class Company(models.Model):
company_id = models.AutoField(primary_key=True)
parent_company = models.ForeignKey("self",null=True,blank=True)
address = models.ForeignKey(Address)
#models.IntegerField(null=True, blank=True)
company_name = models.CharField(blank=True, maxlength=150)
company_description = models.CharField(blank=True, maxlength=300)
update_user =
models.ForeignKey(UserInfo)#models.IntegerField(null=True, blank=True)
time_stamp = models.DateTimeField()
def __str__(self):
return self.company_name
class Meta:
db_table = 'company'
I'm trying to make it so that the Company changemanipulator will
display the Address fields as well so that both can be edited at the
same time. I read something like this in another post on here...but
wasn't sure if it should work or not... below is a snippet of my code:
nonfields = {'time_stamp': False,'address':True }
manipulator = Company.ChangeManipulator(company_id,follow=nonfields)
Then in my form..I tried
Street #:{{
form.address.street_number }}
But that doesn't seem to work... is this not valid... and how should I
be doing it?
Thanks for any info.
