1.在Action中定義，domain用于對象默認的搜索條件：

示例：

<record id="action_orders" model="ir.actions.act_window"><field name="name">Sales Orders</field><field name="type">ir.actions.act_window</field><field name="res_model">sale.order</field><field name="view_type">form</field><field name="view_mode">tree,form,calendar,graph</field><field name="search_view_id" ref="view_sales_order_filter"/><field name="context">{}</field><field name="domain">[('state','not in',('draft','sent','cancel'))]</field><field name="help" type="html"><p class="oe_view_nocontent_create">Click to create a quotation that can be converted into a salesorder.</p><p>OpenERP will help you efficiently handle the complete sales flow:quotation, sales order, delivery, invoicing and payment.</p></field></record> View Code

其中：

?<field name="domain">[('state','not in',('draft','sent','cancel'))]</field>

定義了打開訂單窗口時僅搜索不處于?('draft','sent','cancel') 三種狀態的訂單。

?

2.在對象（或視圖）的關聯字段（many2one和many2many類型字段）中定義，字段值是關聯表的id，domain用于過濾關聯表的記錄：

示例：

_name = 'sale.order.line'_description = 'Sales Order Line'_columns = {'order_id': fields.many2one('sale.order', 'Order Reference', required=True, ondelete='cascade', select=True, readonly=True, states={'draft':[('readonly',False)]}),'name': fields.text('Description', required=True, readonly=True, states={'draft': [('readonly', False)]}),'sequence': fields.integer('Sequence', help="Gives the sequence order when displaying a list of sales order lines."),'product_id': fields.many2one('product.product', 'Product', domain=[('sale_ok', '=', True)], change_default=True),'invoice_lines': fields.many2many('account.invoice.line', 'sale_order_line_invoice_rel', 'order_line_id', 'invoice_id', 'Invoice Lines', readonly=True),'invoiced': fields.function(_fnct_line_invoiced, string='Invoiced', type='boolean',store={'account.invoice': (_order_lines_from_invoice, ['state'], 10),'sale.order.line': (lambda self,cr,uid,ids,ctx=None: ids, ['invoice_lines'], 10)}),'price_unit': fields.float('Unit Price', required=True, digits_compute= dp.get_precision('Product Price'), readonly=True, states={'draft': [('readonly', False)]}),'type': fields.selection([('make_to_stock', 'from stock'), ('make_to_order', 'on order')], 'Procurement Method', required=True, readonly=True, states={'draft': [('readonly', False)]},help="From stock: When needed, the product is taken from the stock or we wait for replenishment.\nOn order: When needed, the product is purchased or produced."),'price_subtotal': fields.function(_amount_line, string='Subtotal', digits_compute= dp.get_precision('Account')),'tax_id': fields.many2many('account.tax', 'sale_order_tax', 'order_line_id', 'tax_id', 'Taxes', readonly=True, states={'draft': [('readonly', False)]}),'address_allotment_id': fields.many2one('res.partner', 'Allotment Partner',help="A partner to whom the particular product needs to be allotted."),'product_uom_qty': fields.float('Quantity', digits_compute= dp.get_precision('Product UoS'), required=True, readonly=True, states={'draft': [('readonly', False)]}),'product_uom': fields.many2one('product.uom', 'Unit of Measure ', required=True, readonly=True, states={'draft': [('readonly', False)]}),'product_uos_qty': fields.float('Quantity (UoS)' ,digits_compute= dp.get_precision('Product UoS'), readonly=True, states={'draft': [('readonly', False)]}),'product_uos': fields.many2one('product.uom', 'Product UoS'),'discount': fields.float('Discount (%)', digits_compute= dp.get_precision('Discount'), readonly=True, states={'draft': [('readonly', False)]}),'th_weight': fields.float('Weight', readonly=True, states={'draft': [('readonly', False)]}),'state': fields.selection([('cancel', 'Cancelled'),('draft', 'Draft'),('confirmed', 'Confirmed'),('exception', 'Exception'),('done', 'Done')], 'Status', required=True, readonly=True,help='* The \'Draft\' status is set when the related sales order in draft status. \\n* The \'Confirmed\' status is set when the related sales order is confirmed. \\n* The \'Exception\' status is set when the related sales order is set as exception. \\n* The \'Done\' status is set when the sales order line has been picked. \\n* The \'Cancelled\' status is set when a user cancel the sales order related.'),'order_partner_id': fields.related('order_id', 'partner_id', type='many2one', relation='res.partner', store=True, string='Customer'),'salesman_id':fields.related('order_id', 'user_id', type='many2one', relation='res.users', store=True, string='Salesperson'),'company_id': fields.related('order_id', 'company_id', type='many2one', relation='res.company', string='Company', store=True, readonly=True),} View Code

其中：

'product_id': fields.many2one('product.product', 'Product', domain=[('sale_ok', '=', True)], change_default=True),

定義了關聯選擇產品時，僅顯示可銷售的產品。

?

3.在搜索視圖中定義，domain用于自定義的搜索條件：

示例：

?

<record id="view_sales_order_filter" model="ir.ui.view"><field name="name">sale.order.list.select</field><field name="model">sale.order</field><field name="arch" type="xml"><search string="Search Sales Order"><field name="name" string="Sales Order" filter_domain="['|',('name','ilike',self),('client_order_ref','ilike',self)]"/><filter icon="terp-mail-message-new" string="Unread Messages" name="message_unread" domain="[('message_unread','=',True)]"/><separator/><filter icon="terp-document-new" string="Quotations" name="draft" domain="[('state','in',('draft','sent'))]" help="Sales Order that haven't yet been confirmed"/><filter icon="terp-check" string="Sales" name="sales" domain="[('state','in',('manual','progress'))]"/><filter icon="terp-dolar_ok!" string="To Invoice" domain="[('state','=','manual')]" help="Sales Order ready to be invoiced"/><filter icon="terp-dolar_ok!" string="Done" domain="[('state','=','done')]" help="Sales Order done"/><separator/><filter string="My Sales Orders" domain="[('user_id','=',uid)]" help="My Sales Orders" icon="terp-personal" name="my_sale_orders_filter"/><field name="partner_id" filter_domain="[('partner_id', 'child_of', self)]"/><field name="user_id"/><field name="project_id"/><group expand="0" string="Group By..."><filter string="Customer" icon="terp-personal" domain="[]" context="{'group_by':'partner_id'}"/><filter string="Salesperson" icon="terp-personal" domain="[]" context="{'group_by':'user_id'}"/><filter string="Status" icon="terp-stock_effects-object-colorize" domain="[]" context="{'group_by':'state'}"/><filter string="Order Date" icon="terp-go-month" domain="[]" context="{'group_by':'date_order'}"/></group></search></field></record> View Code

?

其中：

<field name="name" string="Sales Order" filter_domain="['|',('name','ilike',self),('client_order_ref','ilike',self)]"/>

定義了在搜索視圖中輸入訂單編號時，同時按訂單編號和客戶關聯編號過濾。

<filter string="My Sales Orders" domain="[('user_id','=',uid)]" help="My Sales Orders" icon="terp-personal" name="my_sale_orders_filter"/>

定義了在搜索視圖中選擇"My Sales Orders"標簽時，過濾銷售員是當前登錄用戶的訂單。

?

4.在記錄規則中定義，domain用于定義用戶對對象中記錄訪問的權限：

示例：

<record model="ir.rule" id="sale_order_comp_rule"><field name="name">Sales Order multi-company</field><field name="model_id" ref="model_sale_order"/><field name="global" eval="True"/><field name="domain_force">['|',('company_id','=',False),('company_id','child_of',[user.company_id.id])]</field></record> View Code

其中：

<field name="domain_force">['|',('company_id','=',False),('company_id','child_of',[user.company_id.id])]</field>

定義了用戶僅允許查詢訂單中未指定分公司或訂單中指定的分公司用戶具有訪問權限的銷售訂單。

?

5.domain表達式規則說明：

domain中的單個條件是一個三個元素組成的元組。
第一個是對象的一個column，也就是字段名；
第二個是比較運算符 “=, !=, >, >=, <, <=, like, ilike, in, not in, child_of, parent_left, parent_right“ ；
第三個就是用來比較的值了。
多個條件用“|”（or），“&”（and），“！”（no）邏輯運算符鏈接。
邏輯運算符作為前綴放置于條件前面。“|”與“&”必須兩個條件鏈接，“！”對一個條件取反。默認邏輯運算符為“&”。

舉個例子：

['|', ('project_id.privacy_visibility', '=', 'public'), '&', ('project_id.privacy_visibility', 'in', ['portal', 'followers']), '|', ('message_follower_ids','in', [user.partner_id.id]), ('user_id', '=', user.id), ]

寫個容易看的方式：

[
'|',('project_id.privacy_visibility', '=', 'public'),

　?'&',('project_id.privacy_visibility', 'in', ['portal', 'followers']),

? ? 　?'|', ('message_follower_ids','in', [user.partner_id.id]),
　　　?　 ('user_id', '=', user.id),
]

這個例子的意思是：

(('project_id.privacy_visibility', '=', 'public') or
(('project_id.privacy_visibility', 'in', ['portal', 'followers']) and (('message_follower_ids','in', [user.partner_id.id]) or?('user_id', '=', user.id))))
