[tryton] Re: migration from 3.8 -> 4.0 with webdav

For instance, I find no mention about 'trytond-admin' in the release announcement nor here (at least not what I can find). grepping the Mercurial repository doc/topics/setup_databases.rst indicates only that a database can be initialised with trytond-admin. Yes, my fault for calendar, omitted to update the package list with the new localisations, so 3.8 re-installed instead of 4.0. Updated now via tryton-admin and am trying to get accustomed to the new interface to GL and balance. cheers -- Richard PALO -- You received this message because you are subscribed to the Google Groups "tryton" group.

I think that the problem is self.decoded_data variable because is type
"bytes", I added a "print" before this line and I could confirm this, so
when I convert this variable using .decode("utf-8"), the problem was
solved!.
Do I create an new issue?

Example: - TV1 has 50 records - Select any of the records - Data on TV2 now displays a group of records. Based on the selected record, TV2 data is refreshed.

It is definitely not a bug in 4.0. Your code was working before by
chance. The ORM should never be used during the initialization of the
Pool. Your code doesn't work any more probably because of the
optimization of the pool initialization.
Also you should be careful with global variable, your structure is
probably not thread-safe.
Finally, are you sure you need this? Of course database query is
expensive but included in all the stack of a request, I don't think it
has so much effect.

I think I'm using the Model. __post_setup__ class not correctly, but how
I'm using it is working in Tryton-3.6.5 but not in Tryton-4.0.0 and maybe
there are other ways to do it.
What I'm trying to do, is to build an IOT-platform into Tryton where agents
can connect to and update several values they allowed to change. To
minimize database-queries and updating database-records or inserting new
ones, I build a dict which lives in memory. The agents send the new values
in and Tryton will update the values in the dict, and a cron-job will
archive those values into the database at certain moments. The new values
are also used to trigger events like sending mail, executing scripts etc.
To create the dict in memory I'm using the __post_setup__ class to populate
the dict with the several values.
@classmethod
def __post_setup__(cls):
super(Trigger, cls).__post_setup__()
# get the triggers
triggers = cls.search( [('id', '>', 0 )] )
if triggers:
# Build the datastructure in memory
for trigger in cls.browse( triggers ):
sensors = []
on_activate = []
on_deactivate = []
# get the sensors and conditions
for sensor in trigger.sensor:
if len(sensor.condition) > 2:
sensors.append({
"id": sensor.id,
"sensor": sensor.sensor.id,
"condition" : sensor.condition,
})
# only add the trigger to the list when there are
# sensors and conditions
if len(sensors):
MEM_TRIGGERS.append({
"id" : trigger.id,
"name" : trigger.name,
"sequence" : trigger.sequence,
"min_delay" : trigger.minimum_time_delay,
"min_active" : trigger.minimum_time_active,
"when" : datetime.datetime.utcnow(),
"activated" : trigger.activated,
"enabled": trigger.enabled,
"sensors": sensors
})
I have extended the ir.trigger with
sensor = fields.One2Many('iot.triggersensors', 'trigger', 'Sensor')
And the iot.triggersensors
class TriggerSensor(ModelSQL, ModelView):
"TriggerSensor"
__name__ = 'iot.triggersensors'
name = fields.Char('Name')
trigger = fields.Many2One('ir.trigger', 'Trigger',
domain=[('on_sensor','=',True)], ondelete='CASCADE')
condition = fields.Char('Condition')
This is working in Tryton version 3.65, but in 4.0.0 I get
File "/home/ed/ERP/iot/trytond-4.0.0/trytond/pool.py", line 229, in setup
cls.__post_setup__()
File "/home/ed/ERP/iot/trytond-4.0.0/trytond/modules/iot/iot.py", line
1173, in __post_setup__
for sensor in trigger.sensor:
File "/home/ed/ERP/iot/trytond-4.0.0/trytond/model/modelstorage.py", line
1352, in __getattr__
read_data = self.read(list(ids), ffields.keys())
File "/home/ed/ERP/iot/trytond-4.0.0/trytond/model/modelsql.py", line
744, in read
getter_result = field.get(ids, cls, fname, values=result)
File "/home/ed/ERP/iot/trytond-4.0.0/trytond/model/fields/one2many.py",
line 86, in get
field = Relation._fields[self.field]
AttributeError: type object 'iot.triggersensors' has no attribute '_fields'
So my question is, are there other methods to accomplish this (after the
Tryton-server is started create a dict into memory)? or is this a bug in
Tryton-4.0.0?
Regards,
Ed

This is not particularly linked to Python3. This is bacause relatorio
has a weak dependency on pycha. If you think this behaviour could be
improved you can report it on https://relatorio.tryton.org/

Yes, readfp was changed for read_file in Python 3.2 but it is not
available in Python 2.7. So this feature is kept to ease the transition
between 2 to 3: https://bugs.python.org/issue13248#msg146500
I don't think we should do anything about it until we drop support for
2.7.

I think this one should be reported to python-stdnum:

The code managed this behaviour is:
http://hg.tryton.org/trytond/file/default/trytond/model/modelview.py#l673
With the active record design, it had to choose the behaviour of the
on_change for the One2Many and the Many2Many. We could not mix both
because they have incompatible design (dict actions vs list of ids).
I think the older design was a little bit problematic because when
overriding we could be know which one will be used.
So it was decided to stick on_change behaviour to the default behaviour
of the client which means for One2Many: create, update and delete and
for ManyMany: add/remove.

I think the behaviour of Tryton shows you that there is a design issue
in this code. The tickers should be a Many2Many even if you would like
to have ticket linked to only one sale. I said that because nothing
prevent the user to select a reservation that is already selected on
another sale so you will re-link the tickets from one sale to another.
I think it is not what you want.
If you are using a Many2Many (with a unique constraint), this case will
raise an error and so the user could correct it.
