Odoo12-- statebar根据单据状态动态显示

当状态为草稿或者结算时候，显示结算。

#####当进行结算操作，状态变为‘到期收款’或者其他状态时，就显示单据状态

model.py 文件， ‘dynamic_state’选项为动态显示的内容

state = fields.Selection([
    ('draft', '草稿'),
    ('verify', '已审核'),
    ('due_payment', '到期收款'),
    ('discount', '贴现'),
    ('endorsement', '背书'),
    ('endorsement_return', '背书退回'),
    ('bill_return', '票据退回'),
    ('dynamic_state', '结算'), # 动态显示，设置默认值为'结算'
   ], string='单据状态', copy=False, index=True, track_visibility='onchange', track_sequence=3, default='draft')

xml文件， ‘dynamic_state’ 会根据单据的状态动态显示 dynamic_visible属性中的值

<field name="state" widget="statusbar" readonly="1" statusbar_visible="draft,verify,dynamic_state"

dynamic_visible="due_payment,discount,endorsement,endorsement_return,bill_return"/>

js文件，继承relational_fields.js 。FieldStatus的widget进行重写。

odoo.define('ps_base.statusbar_dynamic_visible', function (require) {

"use strict";

var relational_fields = require('web.relational_fields');

relational_fields.FieldStatus.include({

_setState: function () {

var self = this;

if (this.field.type === 'many2one') {

this.status_information = _.map(this.record.specialData[this.name], function (info) {

return _.extend({

selected: info.id === self.value.res_id,

}, info);

});

} else {

var selection = this.field.selection;

if (this.attrs.statusbar_visible) {

var restriction = this.attrs.statusbar_visible;

if (this.attrs.dynamic_visible) {

var dynamic_state = this.attrs.dynamic_visible.split(",");

if (dynamic_state.indexOf(self.value) !== -1) {

restriction = restriction.replace('dynamic_state', self.value);

}

}

restriction = restriction.split(",");

selection = _.filter(selection, function (val) {

return _.contains(restriction, val[0]) || val[0] === self.value;

});

}

this.status_information = _.map(selection, function (val) {

return {id: val[0], display_name: val[1], selected: val[0] === self.value, fold: false};

});

}

},

});

}

);
