The search you do on name.model is coming up with no results. You should check if record_id contains any records before perfoming a browse on it.

Thanks for replay .I added some code : if record_id: record=self.pool.get('tt_kho').browse(cr,uid,record_id[0],context=context) value['ten']=record.ten else: value['ten']='haha' It looks like it can't get record_id and value['ten'] always = 'haha' ,please help me solve this .Thanks

Hi this is Gulshan Negi

Well, Accessing an index that is too high: This can happen if you have a list of length n and you try to access the element at index n or higher. To fix this, ensure that the index you are trying to access is within the range of the list (ie, between 0 and n-1).

Hope it can help you.

Thanks
