address model
cristi
are build so:
1) is there a way to find out exactly one method of a class where is
used (it's references in the whole project). As an example where is
used name_get from address.py or name_search ,or get_full_address ?
2)I tried to use print for debug (i know is not professional but for
learning purpose is ok)
and i noticed a strange behaviour
i put a print "step1" in write function of the address.py.
then i started the server,started the client,upgraded the party module
and created a new address but
on the server console i did not noticed anything,second time when i
added a new item i saw the "step1"
very easy to reproduce ,have any ideea why ?
3)i noticed this twice in address.py
if isinstance(ids, (int, long)):
ids = [ids]
what this means ?
Regards Cristian.

converts it in a list containing such int or long value.
I guess it's used because ids is supposed to be a list of integers, but
in that case, the system only got a single integer.

Not from tryton. But you can use grep [1] or ack [2]

I use that for debug also and it is professional and even faster then
any debuger :-)

You must save the party to have the addresses saved.

1) Why that is not possible from tryton ?
grep and ack how good are for this purpose.
2) I spoke with Carlos and he told me that is not good to use print
since there are some buffers
and the print is not show imeddiately only when the buffers are empty
and for emptying them some specila coding is needed.
He recommended to me to use import pdb and pdb.set_trace() then i get
the console.
3) ids may be something like [1,2,3,4,5,6] ? or it may be simple 1 so
it is converted to [1]
Now why this is not handled before calling the method ?
How come is possible to get only a number and not a list ?
That is why i would like to knwo where methods are used to be able to
identify such things.

Because it is not the purpose of the application.

I never had any issue to use print statement.

Because anybody can call this function.

This make it more generic.

2,3) clear
1) repeat "is there a way to find out exactly one method of a class

"
i know the purpose of the application ,it's an erp :)
what i asked is on 1) has nothing to do with the purpose of the
application.
it would be very very useful for me to be able to find a mehtod where
is used

But you can not. There is some tools to search for the function string
in the code like grep, ack.

development environment so you should check whatever you are using (vim,
emacs, eclipse, etc...) for the way to do cross code indexing. That
applies to any C/C++/Java/Python/etc... development you work with.
You can read more about vim + ctags at
http://jjinux.blogspot.com/2008/12/vim-ctags.html
Cheers.

Especially when you do debug ....
Imagine you have a huge project...like trytond may be.
I take as example methe name_get this method may be an many other
classes defined so i search only for name_get i get a lot of false
alarms since i might be interested in name_get from address.py.
is this a python issue ?

i did not doubt for a second that this is a functionality that is
related to my development environment.
it ;s crystal clear
but cedk said that this is not suported in tryton and i was surprised
or missundersood since i knew that is an issue that
is not related to a secific project it is more like a python issue.

cannot do such code browsing in Tryton itself. An application cannot
impose rules to the language it uses, so you can use that functionality
just like in other projects, but with the right tools.
Cheers.
cristi
what i exepected from you was somethign this :
such code browsing is not possible in python (implied in tryton as
well) since this is the nature of python. (dynamic type)
so for such thing you neeed runtime in pythons.....
that was magic word missing from all this discussion and the confusion
that is not possible on tryton .
saying that is not possible on tryton does not mean is not possible on
python.
but saying is not possible on python mean is not possilbe on tryton :)

def write(self, cursor, user, ids, vals,
context=None):
if 'party' in vals:
ids = [ids]
context=context):
if address.party.id != vals['party']:
self.raise_user_error(cursor, 'write_party',
context=context)
return super(Address, self).write(cursor, user, ids, vals,
context=context)
is necesarry to do the if isinstance(ids, (int, long)): ?
just to undersand better : in what use case ids=[ids] is executed as
and when not ?
when id is a int and when id is a list ?
from client what do i have to do to have secnario1 when id is an int
and what do i have to do to have the scenario2 when id is a list
Thx (also for patince)

Yes, otherwise you can not loop on the browse because you will receive
only one BrowseRecord instead of BrowseRecordList

It is a coding guidelines, function that use ids must handle both case
single int or list of int.

Now the final question i hope related to this issue:
when ids is a list in this particular case of write on address.py.
So what do i have to do in order to get a list of ids like [1,2,3,4] ?
where do i have to go in the client and what to do in order to have a
list not a single int
?
thx

vim+ctypes or emacs+ctypes to find it not just on this case but also
in following the code on many other future situations...

The check if ids is a list is to be sure that all other models
which (will possibly) inherit Address later are correct programmed.
The methods in party.address model always creating a list for ids,
even if there is only one value inside.
So its just to make the use of the class Address hardened against
programming mistakes in other modules. (Hope that's correct)
One power of Python is that variable typing is 'weak' and not strong:

In a list view for example you can select many records. When you click
on an action button, the ids of the selected records are 'transported'
in the 'ids' variable of the caller of the action method.
