创作需求，如果我们要建设一个大型的中台项目，希望每一个应用都能独立，比如帐号，客户，供应商，产品等，这时我们在创建新应用时就不必为以上的数据再做同步操作，我们基于char来扩展一个查询界面，返回值

我们使用

 widget="xodoo_char_open"

<field name="name" widget="xodoo_char_open"
                                context='{
                                "fun_model":"res.partner",
                                "fun_tree_field":{"fun_model":"res.partner.category","fun_parent":"parent_id","fun_display_name":"name"},
                                "fun_field":"id,name,date,create_date,category_id,user_id",
                                "fun_field_width":{"name":"200","date":"100","create_date":"160","category_id":"160","user_id":"160"},
                                "fun_search_field":{"char":"name,code","data":"create_date,write_date","selection":"type"},
                                "fun_write_field":"name:name:Char,code:name:Char",


                                "fun_windows_title":"查询名称",

                                "fun_mode":"readonly",
                                "fun_lableicon":" fas fa-address-book",
                                "fun_lablename":"",
                                "fun_tooltip_info":"定义查询"
                                }'
                                />

通过上下文我们可以调用任何的远程数据
