我在Odoov9社区的模块上有一个选择字段
但是，每次，我点击它，选择一条记录，它会抛出这个错误：
Error: No conversion for undefined

我不喜欢Odoo的新javascript库，所以，我不知道从哪里开始寻找这个，这是否曾经发生在任何人之前？
提前致谢！
修改
这是发票型号代码（我从中调用它）：
class account_move_line(models.Model):
_inherit = "account.move.line"
document_class_id = new_fields.Many2one(
'sii.document_class',
'Document Type',
related='move_id.document_class_id',
store=True,
readonly=True,
)
document_number = new_fields.Char(
string='Document Number',
related='move_id.document_number',
store=True,
readonly=True,
)
class account_journal_sii_document_class(models.Model):
_name = "account.journal.sii_document_class"
_description = "Journal SII Documents"
def name_get(self, cr, uid, ids, context=None):
result = []
for record in self.browse(cr, uid, ids, context=context):
result.append((record.id, record.sii_document_class_id.name))
return result
_order = 'journal_id desc, sequence, id'
sii_document_class_id = new_fields.Many2one('sii.document_class',
'Document Type', required=True)
sequence_id = new_fields.Many2one(
'ir.sequence', 'Entry Sequence', required=False,
help="""This field contains the information related to the numbering \
of the documents entries of this document type.""")
journal_id = new_fields.Many2one(
'account.journal', 'Journal', required=True)
sequence = new_fields.Integer('Sequence',)
发票视图定义：
<xpath expr="//group[last()]" position="inside">
<filter string="Document Type" icon="terp-folder-orange" domain="[]" context="{'group_by':'sii_document_class_id'}"/>
</xpath>
document_type模型本身：
class sii_document_class(models.Model):
_name = 'sii.document_class'
_description = 'SII Document Class'
name = fields.Char(
'Name', size=120)
doc_code_prefix = fields.Char(
'Document Code Prefix', help="Prefix for Documents Codes on Invoices \
and Account Moves. For eg. 'FAC' will build 'FAC 00001' Document Number")
code_template = fields.Char(
'Code Template for Journal')
sii_code = fields.Integer(
'SII Code', required=True)
document_letter_id = fields.Many2one(
'sii.document_letter', 'Document Letter')
report_name = fields.Char(
'Name on Reports',
help='Name that will be printed in reports, for example "CREDIT NOTE"')
document_type = fields.Selection(
[
('invoice', 'Invoices'),
('invoice_in', 'Purchase Invoices'),
('debit_note', 'Debit Notes'),
('credit_note', 'Credit Notes'),
('other_document', 'Other Documents')
],
string='Document Type',
help='It defines some behaviours on automatic journal selection and\
in menus where it is shown.')
active = fields.Boolean(
'Active', default=True)
dte = fields.Boolean(
'DTE', required=True)
第二次编辑
这是表单视图中的实际字段，每次我点击选择一个文档时都会给出错误：
<h6 style="color:red;text-align:center;text-transform:uppercase;font-weight:900">
<span t-field="o.journal_document_class_id.sii_document_class_id.name"/>
</h6>
答案 0 :(得分：1)
您不能将QWeb用于普通视图定义（公式，树，搜索等）。
您不能在普通视野字段定义上使用点符号。
首先，在您的视图所针对的模型上创建一个相关的Char字段。然后在视图中定义一个简单的字段。
示例（接近上面的代码）：
class my_model(models.Model):
_name = 'my.model'
journal_document_class_id = fields.Many2one(
comodel_name="journal.document.class", string="Journal Doc Class")
# related field
sii_document_name = fields.Char(
string="Sii Document Name",
related="journal_document_class_id.sii_document_class_id.name")
<h6 style="color:red;text-align:center;text-transform:uppercase;font-weight:900">
<field name="sii_document_name"/>
