Master-detail relation, variable scope, passing variables, etc in openerp - odoo

I'm writing a warehouse management module and I came to the inventory step.
I need to make an inventory every now and then for each warehouse separately and each inventory operation will be kept in the database as a master-detail relation,
ie:
one record for the basic data such as id, date, warehouse_id etc. and
this will be recorded in a table created by (inventory) object.
many records will keep the details of the operation (one record for each material) recording the material id, inventory id, balance, etc. and this will be recorded in the table (inventory_lines).
During the data entry, when the user selects a material, I need to check its current balance and display it in the balance field. In order to do this, I'll need to know the warehouse id because every warehouse shall have separate inventories.
I have many materials stored in many warehouses.
For example: I can have a quantity of 5 pens in warehouse A and 10 pens in warehouse B and 6 pens in warehouse C.
First, I select the warehouse (A or B or C) --- let's say warehouse B
Then I select the material (Pen or notebook or whatever) --- let's say Pen
Now, I want to search the database to find the balance of (Pen) in (Warehouse B)
I can write something like this:
select balance from inventory_lines where material_id=mmmmmm and warehouse_id=wwwwww
So, I need to get the material id (mmmmm) and the warehouse id (wwwww)
And that will be done with each material I choose.
The warehouse id is in the column: inventory_id in the object: inventory
'warehouse_id' : fields.many2one('makhazen.warehouse', 'Warehouse Name',required=True),
The material id is in the column: material_id of the object inventory_line as in the picture in the question
'material_id' : fields.many2one('makhazen.material' ,'Material Name'),
I faced the following problem:
I could use the (on_change) method in the form view on the material_id field and could trigger a method to search for the balance in the database but I needed the warehouse_id which I couldn't get.
The questions are:
- How are this master-detail relationship is handled in openerp? how values are passed between the master table and the details table?
- How can we extend the scope of the warehouse_id so that it can be seen from any method in the module?
- I could change the values of the fields by calling a method and returning the desired values in a dictionary, but how to do the opposite (read them)?
It's very critical matter to me.

Firstly, you don't need the warehouse_id field in the wh_inventory_line class. You can always access it trough the the parent object:
inventory_line = self.pool.get('wh.inventory.line').browse(cr, uid, line_id)
wharehouse_id = inventory_line.inventory_id.warehouse_id.id
Secondly, in your case you can just pass the warehouse_id value as parameter to your onchange method. Something like this:
<field name="material_id"
on_change="onchange_material_id(material_id, warehouse_id)"/>
or, if you follow my first advice and remove the warehouse_id from wh_inventory_line:
<field name="material_id"
on_change="onchange_material_id(material_id, parent.warehouse_id)"/>
EDIT
After testing on OpenERP 6.0 I found some errors in your code. I'm just wondering how did you manage to run it.
First, you missed a quote (\') on the warehouse_id column definition of your wh.inventory model:
_columns = {
'date': fields.datetime('Date'),
'warehouse_id': fields.many2one('wh.warehouse', 'Warehouse Name, required=True),
Second, the fields.char() field definition takes at least size parameter additionally to the supplied Field Name. Again, you missed a quote on the following line:
'notes': fields.char('Notes),
Not an error but something you should consider too - you tagged your question with the openerp-7 tag. In OpenERP v7 inheriting from osv.osv is deprecated. Inherit from osv.Model instead.
If I insist on your errors it's because the solution I proposed to you is working fine on my side. So there must be some little error somewhere that prevents your code for doing what is expected.
Here is my test code. You can try it:
wh.py

How to keep the order of the records added in a many2many field the way I wrote them?

I want to keep the order of the records in the many2many field, the way I added them using the write method, but Odoo use the alphanumerical order by default and overwrote the order I put them in. How can I keep it in the same order when I wrote them, is that possible ?
Here is the model code:
# -*- coding: utf-8 -*-
from odoo import models, fields, api
class projet_richat(models.Model):
_inherit = 'project.task'
competence_ids = fields.Many2many('competence.competence',string='Compétences')
consultants=fields.Many2many('hr.employee', string="Consultants")
def search_comp(self):
if len(self.competence_ids) != 0:
consults=self.env['hr.employee'].sudo().search([])
list=[]
for cmp in self.competence_ids:
print(cmp.competence)
for cons in consults:
print(cons.name)
for c in cons.competences:
if c.competence.competence==cmp.competence:
list.append((cons.id,c.competence.competence,c.niveau))
sorted_by_level = sorted(list, key=lambda tup: tup[2], reverse=True)
print(sorted_by_level)
for sorted_cons in sorted_by_level:
self.write({'consultants': [[4, sorted_cons[0]]]})
and here is the view code:
<odoo>
<data>
<record model="ir.ui.view" id="project_inherit_form">
<field name="name">project.inherit.form</field>
<field name="model">project.task</field>
<field name="type">form</field>
<field name="inherit_id" ref="project.view_task_form2"/>
<field name="arch" type="xml">
<field name="user_ids" position="before">
<field name="competence_ids" widget="many2many_tags"/>
</field>
<field name="parent_id" position="after">
<field name="consultants">
<tree>
<field name="name"/>
</tree>
</field>
</field>
<button name="action_assign_to_me" position="after">
<button name="search_comp" string="Test" class="btn-primary"
type="object"
/>
</button>
</field>
</record>
</data>
</odoo>
Thanks in advance.
The many2many field will use the list view to show its content, the default order is defined by the _order attribute on the related model.
You can alter the default ordering by setting the default_order parameter on the tree tag
From the List view documentation:
default_orderoverrides the ordering of the view, replacing the model’s order (_order model attribute). The value is a comma-separated list of fields, postfixed by desc to sort in reverse order:
<tree default_order="sequence,name desc">
To keep the order you want, you can add an integer field sequence and use it to order records (_order='sequence') then in search_comp function set the sequence field value for each line

Adding a field to sale order lines in sale orders

I want to add a computed field "markup" to sale order lines in sale orders (quotes/sales orders).
I have created the model:
class SaleOrderLine(models.Model):
_inherit = "sale.order.line"
markup = fields.Float(compute='_compute_markup', digits=dp.get_precision('.2f%'), store=True)
def _compute_markup(self, order_id, product_id, product_uom_id):
frm_cur = self.env.user.company_id.currency_id
to_cur = order_id.pricelist_id.currency_id
purchase_price = product_id.standard_price
if product_uom_id != product_id.uom_id:
purchase_price = product_id.uom_id._compute_price(purchase_price, product_uom_id)
ctx = self.env.context.copy()
ctx['date'] = order_id.date_order
price = frm_cur.with_context(ctx).compute(purchase_price, to_cur, round=False)
return price
And a new view which inherits sale.view_order_form:
<?xml version="1.0"?>
<odoo>
<record id="view_order_form_margin" model="ir.ui.view">
<field name="name">sale.order.form.margin</field>
<field name="model">sale.order</field>
<field name="inherit_id" ref="sale.view_order_form"/>
<field name="arch" type="xml">
<xpath expr='//field[#name="order_line"]/form/group/group/field[#name="price_unit"]' position="before">
<field name="markup"/>
</xpath>
</field>
</record>
</odoo>
But the field is not shown (the view appears when you check views that inherit current view). I have reloaded everything, restarted the server and cleared the browser cache.
Any tip on why the field is not being shown is welcomed. Maybe the Xpath expression?
Thanks.
may be in sale.order view price_unit getting 2 times so it's confusion where to add and sale order view consist as formview and tree view for the sale orderline.here is the code you can get in view.
formview:
<xpath expr="//notebook//page//field//form//field[#name='price_unit']" position="before">
<field name="markup"/>
</xpath>
in Tree View:
<xpath expr="//notebook//page//field//tree//field[#name='price_unit']" position="before">
<field name="markup"/>
</xpath>

As you see URLList displayed fine. For class SiteTrip present problem. Field is displaying not data from URLList. This is field stored element such webvisitorcalc.url_list.ID (array?). How I can display real data in this field (for example URL: http://some-site.com/page.html)?
URL in URLList must be uniq. SiteTrip must have stored only ID of URLList record.
UPD:
class RemoteSites(models.Model):
_name = 'webvisitorcalc.remote_sites'
site_id = advert_company_id = fields.One2many('webvisitorcalc.site_list', 'remote_sites_ids', string='Site')
site_url_ids = fields.Many2one('webvisitorcalc.url_list', string='URL page ')
target_url_ids = fields.Many2one('webvisitorcalc.url_list', string='URL target page')
You obviously have no name field on your webvisitorcalc.url_list model. Odoo needs this to use it as name in webclient wherever you use this model as e.g. many2one field or in the breadcrumb navigation.
So either you define a name field or you set _name on your class with another field identifier.
You can also (re-)define the method display_name on your model (enough examples in Odoo code) where you can do more cool stuff with the record display name :-)

OpenERP - Show child_ids invoices of a partner

I'd like to show invoices adressed to child partner in the parent partner form view.
I've already a inherited res_partner model as follow :
class res_partner(osv.osv):
_inherit = 'res.partner'
_columns = {
'invoice_ids': fields.one2many('account.invoice', 'partner_id', 'Invoices'),
}
And a view displaying invoices as follow :
<?xml version="1.0"?>
<openerp>
<data>
<!-- Partners inherited form -->
<record id="view_history_partner_info_form" model="ir.ui.view">

With this code I can see invoices that are directly adressed to a company or a person on their respective form view.
But if an invoice is adressed to person, and none is adressed to the parent company, when I am on the company form view, I won't see the invoice adressed to the child contact.
Is there a way to make visible the contact's invoice in the parent partner form view ?
Thank you for your help !
Cheers
One way to do this is to add a new field, all_invoice_ids, as a function field, and then have the function return both the contents of invoice_ids, plus the contents of any child's invoice_ids.
Something like this (untested):
'all_invoice_ids': fields.function(
_get_invoice_ids,
type='one2many',
obj='account.invoice',
method=True,
string='Invoices',
),
and _get_invoice_ids (which should be defined before columns) like this (also untested):
def _get_invoice_ids(self, cr, uid, ids, field_name, arg, context=None):
res = {}
if isinstance(ids, (int, long)):
ids = [ids] # in case an id was passed in directly
for main_partner in self.browse(cr, uid, ids, context=context):
main_invoices = main_partner.invoice_ids or [] # in case it was False
invoices = [inv.id for inv in main_invoices]
for child_partner in main_partner.child_ids:
child_invoices = child_partner.invoice_ids or []
invoices.extend([inv.id for inv in child_invoices])
# at this point we should have all the invoice ids
# use a set to get rid of duplicates
invoices = list(set(invoices))
# and store in res to be returned
res[main_partner.id] = invoices
return res

Can we add Date range in Group by search filters in Openerp 7.0?

In OpenERP 7 Is it possible to add From and To date in "Group By Filter" ?.. if possible please give me steps how to add in group by filter date range
import time
import netsvc
from osv import fields, osv
from openerp.tools import DEFAULT_SERVER_DATE_FORMAT, DEFAULT_SERVER_DATETIME_FORMAT, DATETIME_FORMATS_MAP, float_compare
class sale_order(osv.osv):
_inherit = "sale.order"
_columns = {
'order_date_from':fields.function(lambda *a,**k:{}, method=True, type='date',string="Order date from"),
'order_date_to':fields.function(lambda *a,**k:{}, method=True, type='date',string="Order date to"),
}
sale_order()
Here I've given the ex for 'Order Date' in Sale Order module. Try the codes. Hope it will solve ur problem.
<record id="sale_order_period_filter" model="ir.ui.view">
<field name="name">sale.order.period.filter</field>
<field name="model">sale.order</field>
<field name="inherit_id" ref="sale.view_sales_order_filter"/>
<field name="arch" type="xml">
<field name="name" position="after">
<field name="order_date_from" filter_domain="[('date_order','>=',self)]" widget="calendar"/>
<field name="order_date_to" filter_domain="[('date_order','<=',self)]" widget="calendar"/>
</field>
</field>
</record>
You can define group by filter in xml.
<filter string="Month" name="groupbymonth" icon="terp-personal" domain="[]" context="{'group_by':'visitdate'}" />
Domain looks like,
domain="[('visitdate', '>=', time.strftime('%%Y-%%m-%%d 00:00:00')),('visitdate', '<=', time.strftime('%%Y-%%m-%%d 23:59:59'))]"
You need to add domain like given above into the group by filter,
this is the example, you need to change it to your requirement.
I hope this helps you.
