"AttributeError: 'tuple' object has no attribute 'items'" when modifying sale order line via custom code

Hello everybody

I have this issue, I have different product categories, let's say cat1, cat2, cat3, and for each of these categories I have defined 2 new fields: "halfcontop" and "highcontop", what they do is to estblish 2 product quantities for getting special price. Now, all my products belong to one of the previous categories and each of my products also have two fields : "prhalfc" and "prhighc" which are my special prices for each product. Now, comes the interesting thing: these prices are reachable depending on the quantity of products by category, and not by the quantity of items of this product , for example, let's think that for cat1, highcontop=10 and I have 11 different products belonging to this category so that if I buy only one of each of these products Im gonna have 11 products and then Im gonna reach "prhighc" for each product which may be different for all products.

I have analyzed the problem and I think that what I should do is to browse the whole sale order, so that I can count the number of products by category, and then, according to this number establish the new prices if necessary.

I also took a deep look at pricelist module, but it doesn't fit my neccesity because it changes the product prices for each line, and what I need to do first is the check the whole sale order.

I have done the following points. But I stiil need some help. Thanks in advace for suggestions!!

This is the code for new fields, everything is fine here:

PY:

from openerp import netsvc from openerp import pooler from openerp.osv import fields, osv, orm from openerp.tools.translate import _

class product_otherprices_inherit(osv.osv): _inherit = 'product.product' _name='product.product' _columns = { 'prhalfc' : fields.float('Price for half consume', help='Enter the price defined for half consume'), 'prhighc' : fields.float('Price for high consume', help='Enter the price defined for high consume'), } class category_price_range_inherit(osv.osv): _inherit = 'product.category' _name = 'product.category' _description = 'Ranges for category prices half & high consume' _columns = { 'halfcontop':fields.float('Range top for half consume',help='Top for half consume'), 'highcontop':fields.float('Range top for high consume',help='Top for high consume'), }

XML:

<openerp> <data> <record model="ir.ui.view" id="product_otherprices_inherit"> <field name="name">product.otherprices.inherit</field> <field name="model">product.product</field> <field name="inherit_id" ref="product.product_normal_form_view"/> <field name="arch" type="xml"> <notebook position="inside"> <page string="Other_Prices"> <group> <field name="prhalfc"/> <field name="prhighc"/> </group> </page> </notebook> </field> </record> </data> </openerp>

<openerp> <data>

    <record model="ir.ui.view" id="category_price_range_inherit">
        <field name="name">product.category.pricerange.inherit</field>
        <field name="model">product.category</field>
        <field name="type">form</field>
        <field name="inherit_id" ref="product.product_category_form_view"/>
        <field name="arch" type="xml"> 

            <sheet> 
                <group> 
                    <group name="parent" col="4"> 
                        <field name="lowcontop" /> 
                        <field name="halfcontop"/> 
                        <field name="highcontop"/> 
                    </group> 
                </group> 
            </sheet>
        </field>
    </record>
</data>

</openerp>

Now, comes the method supossed to change the prices, but it stiil doesn't work

class sale_order_line(osv.osv):

_inherits = 'sale.order.line', 'product.product', 'product.category'
_name="sale.order.line"

def _category_amount_line(self, cr, uid, ids, field_name, arg, context=None):
    tax_obj = self.pool.get('account.tax')
    cur_obj = self.pool.get('res.currency')
    res = []
    if context is None:
        context = {}
    for line in self.browse(cr, uid, ids, context=context): #Lo que intento es que haga referencia a los campos puestos e las clases anteriores, segun entendi, esta funcion compute_all, lo unico que hace es un redondeo con los decimales.
        taxes = tax_obj.compute_all(cr, uid, line.tax_id, line.prhalfc, line.prhighc, line.product_uom_qty, line.order_id.partner_invoice_id.id, line.product_id, line.order_id.partner_id)
        cur = line.order_id.pricelist_id.currency_id
        res[line.id] = cur_obj.round(cr, uid, cur, taxes['total'])
    return res




def product_id_change(self, cr, uid, ids, pricelist, product, qty=0,
        uom=False, qty_uos=0, uos=False, name='', partner_id=False,
        lang=False, update_tax=True, date_order=False, packaging=False, fiscal_position=False, flag=False, halfcontop=0, highcontop=0, prhalfc=0, prhighc=0, context=None):

    res=[]
    res =  super(sale_order_line, self).product_id_change(
        cr, uid, ids, pricelist, product, qty,
        uom, qty_uos, uos, name, partner_id,
        lang, update_tax, date_order, packaging, fiscal_position, flag, halfcontop, highcontop, prhalfc, prhighc, context=context)
    cat_ids=[]
    for product in product.browse(cr, uid, uid):
        if product.categ_id.id not in cat_ids:
            cat_ids.append(product.categ_id.id)
    cats = pool.get('product.category').name_get(self.cr, self.uid, cat_ids, context=self.localcontext)        
    #Segun yo , hasta esta parte, hemos conseguido las categorias, me base en product_pricelist.py(funcion _get_categories)
    for cat in cats:
        x=0.0
        for product in product.browse(cr, uid, ids):
            if cat == product.product.category_id :
                 x = product.product_uom_qty  + x   #product.qty
        for product in product.browse(cr, uid, ids): 
            if cat == product.product.category_id:

                if x >= product.category.halfcontop and  x < product.category.highcontop :

                    res['price_unit'] = product.prhalfc

                elif x >= product.category.highcontop :

                    res['price_unit'] = product.prhighc

                else :

                    res['price_unit'] = product.price_unit  
    return res

and now the XML, with onchange method:

XML:

<openerp> <data> <record id="view_sale_order_form_minimalprice_form" model="ir.ui.view"> <field name="name">sale.order.form - minimal price</field> <field name="model">sale.order</field> <field name="type">form</field> <field name="priority" eval="20"/> <field name="inherit_id" ref="sale.view_order_form"/> <field name="arch" type="xml"> <data> <xpath expr="//field[@name='price_unit']" position="attributes"> <attribute name="on_change">product_id_change(parent.pricelist_id, product_id, product_uom_qty, product_uom, product_uos_qty, product_uos, name, parent.partner_id, False, True, parent.date_order, False, parent.fiscal_position, False, halfcontop, highcontop, prhalfc, prhighc, context)</attribute> </xpath> </data> </field> </record> </data> </openerp>

and fnally, whe trying to install it,, I get the following error:
