[tryton] When creating manually a new move from a storage location, button "do" is readonly

[Maxime Richez]

Hello, 

When creating manually a new move with a "storage location" as from_location, 
assignation is required but "assign" button is invisible (and "do" button is 
readonly) so can't go on, bug ?

[tryton] setting cost_price readonly when using "average cost price" method

[Maxime Richez]

hi, wondering why field cost_price on variant is not readonly when choosing 
average cost_price method ? Because if you set any value on the cost_price, 
it's updated when you recompute cost price... feature ?

[Maxime Richez]

In our case, the split has to be done before the reception and changing 
quantity on the shipment create another shipment with the missing quantities 
when you click on receive. We prefer to split incoming moves while they are in 
'draft' state, then giving each line a lot number and when we receive goods we 
validate the reception.

Indeed, i add the code and it's working. Thanks !

[tryton] Split moves on shipment in

[Maxime Richez]

Hi,

Is there a problem to split moves on shipments in ?

For example, we receive an order of 100 items packaged in 10 boxes... we 
would like to assign a lot number on each received box before internal shipment 
(we need to prepare lot creation (which is complex) before shipment in).
We saw in stock_split module code, this is not active for shipment in, is there 
any reason ? 

Could we just add this code :

class ShipmentIn(_ShipmentSplit):

__metaclass__ = PoolMeta
__name__ = 'stock.shipment.out'

Thanks !

2 questions:

- In the case of the function field is only used in a treeview for filtering 
data (just for display), isn't better to define a new modelview based on a 
query (for example: 
https://bitbucket.org/zikzakmedia/trytond-product_quantity_by_location/src ) 
Would it be more optimal ?

- What about the search function if one of the field to compare with another 
field is already a function field (for example product quantity field)? Is the 
only way of doing the search is still the query (that would be very complex in 
the case of quantity field,no ?) ?

[tryton] Domain with function field

[Maxime Richez]

Hi,

In domain definition, operand cannot be a field. So, i'm wondering how doing 
this kind of view: for example, a listing of all products having a cost_price 
greater than list price.
I would define this domain ['cost_price', '>', Eval('list_price')] but this is 
not working.
Another idea, was to define a function field on a boolean field (flag) and the 
setter of this function field will return true or false about the comparison 
between 'cost_price' and 'list_price'... and then creating a treeview with 
domain ['flag', '=' ,'True'] but once again, how to define a correct domain in 
the searcher function of the flag function field ?
Thanks for ideas, help...

[tryton] Tryton Docker instructions

[Maxime Richez]

Hi,

Yesterday, i made tryton docker installation following instructions on the 
docker page: https://hub.docker.com/r/tryton/tryton/

I noticed that created volumes at the first instruction are never used because 
other instructions never use them...

To use the "postgres" volume, the instruction "Start a PostgreSQL instance" 
should be:

sudo docker run --name tryton-postgres -v postgres:/var/lib/postgresql/data -e 
POSTGRES_PASSWORD=mysecretpassword -e POSTGRES_DB=tryton -d postgres

Don't know if it's really needed to create a tryton volume, as the only volume 
that could be exposed in tryton docker is "/var/lib/trytond/db". Maybe if we 
plan to use an sqlite database? Else it seems useless...

I would like also sharing a nice tool to easily manage your docker environment:

No, those parts are used for repairing machines used by production.But we 
have a lot of machines, (and then a lot of spare parts), so we keep them in 
stock with inventory.
Production machine consume other products.

 Thanks for your suggestion... Always interesting to know how other people 
proceed... and the best way to apply this "behaviour" in tryton. 
We are doing the same thing with our printer toners: we keep them in stock 
(with inventory), and each time an employee needs one,  an output move 
should be done to update stock.

[tryton] Stock moves

[Maxime Richez]

Hi,

We have a specific warehouse with spare parts for repairing machines. Those 
"products" are not considered as consumables because we need an inventory.
What is the best way to output those products ? Internal shipment to Lost 
and Found or a specific location ? Create a "manual move" to a specific 
output zone (but it needs an invoice line...) ?
Is there a specific module or wizard to output product in stock for a such 
case... (not a sale not an inventory)

[tryton] Installing tryton server - How to ? and some questions...

[Maxime Richez]

Hi,

This subject is often coming back on the forum. 

We need some advices to correctly install trytond 4.2 on a debian server… 
(for production or testing)


Here are our first steps  on a debian 9.0 :


- installing some packages : *sudo apt install python virtualenv mercurial 
python-pip*


- creating « tryton » user : *sudo adduser tryton*


*Using user « tryton » :*


- creating directory where to install tryton : 

*mkdir /srv/tryton/4.2*


- *pip install hgnested* 

and configuring .hgrc in /home/tryton :

*[ui] *

* username = Tryton  *

* [extensions] *

* hgnested = *


- defining virtualenv in /srv/tryton/4.2 : 

*virtualenv .venv/tryton*


- switching into virtualenv : 

*/srv/tryton/4.2/source .venv/tryton/bin/activate*


- cloning in /srv/tryton/4.2 trytond 4.2 and all the modules with nclone :

*hg nclone http://hg.tryton.org/4.2/trytond -b 4.2*


- configuring trytond.cfg to use postgresql database :

*[database]*

*uri = postgresql://tryton:tryton@postgresqlsrv:5432/*


*Questions ?*


« pip install . » or « python setup.py install » ?  


How to install all python dependencies for all the modules ?


- Is there a list with all the requirements to use with pip ?

- Should i execute trytond-admin –all and install dependencies one by one 
each time i get an error ?

- What about issue https://bugs.tryton.org/issue5960 ?


Waiting for your advices/suggestions... Then we could add this "how-to" to 
documentation..
Thanks !

[tryton] sequence_order

[Maxime Richez]

Hi,

I noticed a strange behaviour with the drag'n'drop automatic sequence order.
Let's take a purchase with 3 purchase_lines that we want reorder:
by default sequence field is empty on the 3 lines. If i drag 'n 'drop the 
last line to the first position and i save, this line will be in second 
position (???) (one sequence will stay empty and the other one will be '1').
Now if i drag''n'drop the second line to first position and i save, it will 
be ok. (sequence is still empty on the first line, and there'll be also '1' 
on the other line).
Next step, i take my first line and i put it in second position : when i 
save, this line will be in third position (with sequence '2' and the two 
others lines will have sequence '1').

Normal behaviour or bug ? Should not all the line renumbered when 
reordering ?

[tryton] Adding validity dates for product supplier price

[Maxime Richez]

Hi, 

I would like to add start_date and  end_date for a product supplier price.

Here's my code:

http://pastebin.com/Bm9GwTps

My problem:

get_purchase_price method is called  from PurchaseLine with a specific 
context (purchase_date,...) then get_purchase_price check if there's 
product_supplier_price matching.
How to keep previous context to check if purchase_date is between 
start_date and end_date ?
Thanks for your help !

Effectively, my rule is not added for a user, i'll set rule default.
And how to add a rule to a specific user in the xml file ? 
How can i apply my domain only when user try to modify a record ? Because

[tryton] Error : Model has no attribute ... when function field is not in my xml form view (visible or not)

[Maxime Richez]

Hi,

I have 2 classes (HEADER and LINES)

HEADER has a function field currency (because currency need to be stored on 
the LINES):

currency = fields.Function(fields.Many2One('currency.currency', 'Default 
Currency',
states=_STATES, depends=_DEPENDS),'on_change_with_currency')
...

@fields.depends('party','company')
def on_change_with_currency(self, name=None):
cursor = Transaction().connection.cursor()
Purchase = Pool().get('purchase.purchase')
table = Purchase.__table__()
if self.party:
subquery = table.select(table.currency,
where=table.party == self.party.id,
order_by=table.id,
limit=10)
cursor.execute(*subquery.select(subquery.currency,
group_by=subquery.currency,
order_by=Count(Literal(1)).desc))
row = cursor.fetchone()
if row:
currency_id, = row
return currency_id
#cls.currency_digits = self.currency.digits
elif self.company:
return self.company.currency.id
return None

LINES has also a currency field but a many2one (with as default value, 
currency from HEADER) :

currency = fields.Many2One('currency.currency', 'Currency',
states={
'required': Bool(Eval('unit_price')),
},
depends=['unit_price'])
...

@fields.depends('_parent_HEADER.currency','HEADER')
def on_change_with_currency(self):
currency = self.HEADER.currency if self.HEADER else None
if currency:
return currency.id


Currency on the HEADER doesn't need to be displayed, so this field is not 
in the xml form view. 
When i try to create a new LINE with a new HEADER, i got this error : 
'header' Model has no attribute currency 
If i had the currency field in the xml form view of the HEADER (visible or 
not) , there is no error... 
Why ?

Hope my explanations are understandable :-)

I follow your advice but how to force the "on_change_with" be executed and 
set the default value when the form is opened ? Here's is the code of my on 
change:

@fields.depends('_parent_purchase_requisition.currency')
def on_change_with_currency(self):
currency = self.purchase_requisition.currency if 
self.purchase_requisition 
else None
if currency:
return currency.id
else:
Company = Pool().get('company.company')
company = Transaction().context.get('company')
if company:
company = Company(company)
return company.currency.id

You can use an on_change_with that depends on the parent field which will 
be called by the tryton client and you can compute the value as you want.

i think there's no parent field, there's multiples lines...

[tryton] Default value related to the latest data entered ...

[Maxime Richez]

Hello,

Is it possible to define a default value in a field that depends on the 
previously entered data?

For example, I have a model with detail rows (product, quantity, 
prix_unitaire, currency):

By default the value of my currency is the currency of my company.
If I have to introduce more detail lines with a currency different from 
that of my company, to avoid to select this currency every time, is it 
possible to imagine that the default value of the currency come from the 
value of the previous detail row (and if it's the first line the currency 
of the company)? did the context keeps the last entered values?

Thanks for your help...

Thanks for your answer. So, in this case, default view  is move_tree.xml













But there is more fields in the model than displayed in the view of the 
function field.
In shipment_in : (from_location and to_location are invisible for the 
function field "incoming_moves" and "from_location" is invisible for 
function_field "inventory_moves"  and both are using stock.move...

"from_location" and "to_location" in the class Move have the same domain
So i'm still wondering how fields are hidden in the view ?

[tryton] Help about fields displayed by a function field

[Maxime Richez]

Hi everybody,

I'm working with Thierry Bruyere @ SALUC (Chemical industry located in 
Belgium)
We planned to migrate our internal erp tools to Tryton so i'm learning 
Tryton and his code.

Can someone give explanations about the display of a function field in the 
"stock.shipment.in" module. I'm wondering where are defined the displayed 
fields for the function field "incoming_moves" (in this case : product, 
quantity, uom,planned date, effective date, state

I'm analyzing the code, unsuccessfully ... 

in the file shipment_in_form.xml










in shipment.py 

Class ShipmentIn

incoming_moves = fields.Function(fields.One2Many('stock.move', 'shipment',
'Incoming Moves',
add_remove=[
('shipment', '=', None),
('from_location', '=', Eval('supplier_location')),
('state', '=', 'draft'),
('to_location', '=', Eval('warehouse_input')),
],
domain=[
('from_location', '=', Eval('supplier_location')),
('to_location', '=', Eval('warehouse_input')),
('company', '=', Eval('company')),
],
states={
'readonly': (Eval('state').in_(['received', 'done', 'cancel'
])
| ~Eval('warehouse') | ~Eval('supplier')),
},
depends=['state', 'warehouse', 'supplier_location',
'warehouse_input', 'company']),
'get_incoming_moves', setter='set_incoming_moves')


def get_inventory_moves(self, name):
moves = []
for move in self.moves:
if (move.from_location.id ==
self.warehouse.input_location.id):
moves.append(move.id)
return moves
