Question

我试图通过fields.function在wqeb报告中显示图像。在表单内部一切顺利，但是当在qweb中尝试报告时发生此错误，我仍然不明白这个错误的含义。任何帮助将不胜感激，提前谢谢。

  File "/opt/ikom/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：非图像二进制字段无法转换为HTML

我试图通过这种方式获得

   'chart': fields.function(_get_image, string="Grafica de pallets", type="binary"),


    def _get_image(self, cr, uid, ids, name, args, context=None):
       pdb.set_trace()
       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(chart_encoded)
       return res

<span itemprop="image" t-field="o.chart" t-field-options='{"widget": "image", "alt-field": "name"}'/>

我认为你应该用binary字段替换你的函数字段并添加如下内容：

<span t-field="o.image_field" t-field-options="{&quot;widget&quot;: &quot;image&quot;, &quot;class&quot;: &quot;img-rounded&quot;}"/>
