odoo 的加载流程二、load_views

由于加载页面首先显示 load_views,因此分析此函数，看能做什么文章

@api.model
    def load_views(self, views, options=None):
        """ Returns the fields_views of given views, along with the fields of
            the current model, and optionally its filters for the given action.

        :param views: list of [view_id, view_type]
        :param options['toolbar']: True to include contextual actions when loading fields_views
        :param options['load_filters']: True to return the model's filters
        :param options['action_id']: id of the action to get the filters
        :return: dictionary with fields_views, fields and optionally filters
        """
        options = options or {}
        result = {}

        toolbar = options.get('toolbar')
        result['fields_views'] = {
            v_type: self.fields_view_get(v_id, v_type if v_type != 'list' else 'tree',
                                         toolbar=toolbar if v_type != 'search' else False)
            for [v_id, v_type] in views
        }
        result['fields'] = self.fields_get()

        if options.get('load_filters'):
            result['filters'] = self.env['ir.filters'].get_filters(self._name, options.get('action_id'))


        return result

先分析主要函数 fields_view_get

通过调试，先看整体，返回 result

{
   'type':'form',
   'name':'zhy.sale.form'
   'arch':'数据库中 xml内容',
   'model':zhy.sale,
   'fields': '根据权限等可以显示的字段'}

可以看出此函数主要作用根据view_id 。从view 表得到 view model 的详细信息

只看主要信息

 xarch, xfields = View.postprocess_and_fields(self._name, etree.fromstring(result['arch']), view_id)
        result['arch'] = xarch
        result['fields'] = xfields

xarch 就是数据库里面的内容，xfields 是 modle 的所有字段

进入VIEW 的函数，可以看到重要的信息

#递归处理字段
        fields_def = self.postprocess(model, node, view_id, False, fields)
        self._postprocess_access_rights(model, node)
        return arch, fields

递归处理权限和字段。下一篇分析 view 的 postprocess (xml->modle )的函数
