odoo里面context用法 原文转自：https://www.cnblogs.com/zhaoweihang/p/9698852.html   field name=\partner_id\ string=\Customer\ widget=\res_partner_many2one\ context=\{\'default_name\': contact_name, \'default_street\': stre

context   这是一个上下文，运用很灵活  得到整个context   self.context_get()

self.env[\'res.users\'].context_get() 得到context里面对应的值 得到flag的值     self.env.context.get(\'flag\',False)

修改context里面的对应的值   self.with_context({\'flag\': False})   或   self.with_context(flag=True) 单一时   或   ctx = dict(context or {})   ctx[\'flag\']=False   self.with_context(ctx)

保证context的字典类型   context = dict(context or {})

复制context   c = context.copy()   主要改变部分值，带到其它函数中

自己构造context   context = {\'flag\':Fasle,\'lang\':\'zh_cn\'}

常规用法  

带入函数中    

if part.lang:       

self = self.with_context(lang=part.lang)     

product = self.env[\'product.product\'].browse(product)

------   

　　 return self.with_context(ctx).write({\'invoice_line\': []})   

记住,用了 with_context

视图中引入

context   model="ir.actions.act_window"时   {"search_default_my_export_list":1}  

代表 搜索时 my_expert_list 值为1 对于 search_default_是系统的前置标识

设置值：获取表单中的字段：【字段1、字段2】

     self.with_context({\'字段1\': \'aaaaaa\',\'字段2\': \'bbbaaa\'})

获取值：

self._context.get(\'字段1\')

@api.multi

""" Low-level method - Mono pricelist, multi products

self.ensure_one()
if not date:
date = self._context.get(\'date\') or fields.Date.context_today(self)
if not uom_id and self._context.get(\'uom\'):
uom_id = self._context[\'uom\']
if uom_id:
# rebrowse with uom if given
products = [item[0].with_context(uom=uom_id) for item in products_qty_partner]
products_qty_partner = [(products[index], data_struct[1], data_struct[2]) for index, data_struct in enumerate(products_qty_partner)]
else:
products = [item[0] for item in products_qty_partner]

if not products:
return {}
