本文介绍8.0版本中两种API实现方式下，如何通过model字段设置进行控件的数据获取与设置操作，包括旧API（osv.osv）和新API（models.Model）的对比，并给出具体代码实例。
#控件使用说明
--model字段设置
--8.0版本老的api
class demo(osv.osv):
def _data_get(self, cr, uid, ids, name, arg, context=None):
if context is None:
context = {}
datas = []
att = self.pool.get('ir.attachment')
attIds = att.search(cr, uid, [('res_model','=',self._name),('res_id','=',ids[0])])
attObjs = att.browse(cr, uid, attIds)
for i in attObjs:
if i.file_type_icon!='webimage':
html = """
""" % {
'parentModel':self._name,
'parendId':ids[0],
'attId':i.id,
'attIcon':(i.file_type_icon or 'unknown'),
'filename':i.name
}
else:
html = """
""" % {'parentModel':self._name,
'parendId':ids[0],
'attId':i.id,
'filename':i.name
}
datas.append({
'id':i.id,
'file_type_icon':i.file_type_icon,
'datas_fname':i.datas_fname,
'data':att._file_read(cr, uid, i.store_fname),
'html':html
})
return {ids[0]:datas}
def _data_set(self, cr, uid, id, name, value, arg, context=None):
return True
_columns = {
'datas': fields.function(_data_get, fnct_inv=_data_set, string='测试附件', type="binary", nodrop=True),
}
8.0版本新的api
from openerp import models, fields
class demo(models.Model):
_inherit = 'demo'
datas = fields.Binary(compute='_data_get', inverse='_inverse_display_name', string='测试附件')
@api.one
def _data_get(self):
context = self.env.context
if context is None:
context = {}
datas = []
att = self.env['ir.attachment']
attObjs = att.search([('res_model','=',self._name),('res_id','=',self.id)])
for i in attObjs:
if i.file_type_icon!='webimage':
html = """
""" % {'parentModel':self._name,
'parendId':self.id,
'attId':i.id,
'attIcon':(i.file_type_icon or 'unknown'),
'filename':i.name
}
else:
html = """
""" % {'parentModel':self._name,
'parendId':self.id,

'filename':i.name

self.datas = datas
