python - 通过 QWeb 报告上的 fields.function 从数据库获取图像 - Odoo 8

Question

我想打印一张图像，通过 fields.function 获取数据库中的任何图像。

我正在尝试以下操作:

def _get_image(self, cr, uid, ids, name, args, context=None):
    res = dict.fromkeys(ids)
    for record_browse in self.browse(cr, uid, ids):
        partner = self.pool.get('res.partner').browse(cr,uid,6,context=None).image
        res[record_browse.id] = base64.encodestring(partner)
    return res   

_columns = {
        'image': fields.function(_get_image, string="Image", type="binary"),
}

但在 qweb 报告中我得到:

  File "/opt/*/openerp/addons/base/ir/ir_qweb.py", line 791, in value_to_html
raise ValueError("Non-image binary fields can not be converted to HTML")
ValueError: Non-image binary fields can not be converted to HTML

如果我以表单打印图像，一切都会顺利。

如有任何帮助，我们将不胜感激，提前致谢。

试试这个代码:

def _get_image(self, cr, uid, ids, name, args, context=None):
    res = dict.fromkeys(ids)
    for record_browse in self.browse(cr, uid, ids):
        partner = self.pool.get('res.partner').browse(cr,uid,6,context=None).image
        res[record_browse.id] = base64.encodestring(partner)
    return res   

_columns = {
        'image': fields.binary("Image"),
        'image_x': fields.function(_get_image, string="Image", type="binary"),

}
