迁移模块从10到12

Question

我正在尝试将模块从Odoo 10迁移到12，但它向我显示了这个错误，我不明白为什么：

属性中使用的字段“状态”必须存在于视图中但缺失

你能帮我解决一下这个问题：

Field 'state' used in attributes must be present in view but is missing:
 - 'state' in attrs="{'invisible': ['|','|',('journal_entry_ids', '!=', []), ('state', '=', 'confirm'),('type', '!=', 'bank')]}"
 - 'state' in attrs="{'invisible': ['|','|',('journal_entry_ids', '=', []), ('state', '=', 'confirm'),('type', '!=', 'bank')]}"

                </form>
            </xpath>
        </data>
    </field>
</record>

该错误表示父视图中不存在属性“state”，但它存在。

这是父视图：

<record id="view_bank_statement_form" model="ir.ui.view">
    <field name="name">account.bank.statement.form</field>
    <field name="model">account.bank.statement</field>
    <field name="priority">1</field>
    <field name="arch" type="xml">
        <form string="Bank Statement">
        <header>
            <field name="all_lines_reconciled" invisible="1" />
            <button name="%(action_bank_reconcile_bank_statements)d" string="Reconcile" type="action" class="oe_highlight" attrs="{'invisible':['|','|',('all_lines_reconciled','=',True),('line_ids','=',[]),('state', '!=', 'open')]}"/>
            <button name="check_confirm_bank" string="Validate" type="object" class="oe_highlight" attrs="{'invisible':['|','|',('all_lines_reconciled','=',False),('line_ids','=',[]),('state', '!=', 'open')]}"/>
            <field name="state" widget="statusbar" statusbar_visible="open,confirm"/>
        </header>
        ...
    </field>
</record>

Answer 1

当你写这样的东西：

<xpath expr="//field[@name='line_ids']/tree/field[@name='bank_account_id']" position="after">
    ...
</xpath>

你在那里添加的所有内容都与x2many字段line_ids的模型及其树视图有关。因此，如果添加带有attrs参数的新字段/按钮，则必须检查域左侧的属性是否位于line_ids的树视图内，而不是account.bank.statement的形式。

因此，您必须将字段状态添加到字段line_ids的树视图中：

<xpath expr="//field[@name='line_ids']/tree/field[@name='bank_account_id']" position="after">
    <field name="type" invisible="1"/>
    <field name="state" invisible="1"/>
    <button name="select_account_move_line" type="object" icon="fa-registered" attrs="{'invisible': ['|','|',('journal_entry_ids', '!=', []), ('state', '=', 'confirm'),('type', '!=', 'bank')]}"/>
    <button name="cancel_reconciliation" type="object" icon="fa-chain-broken" attrs="{'invisible': ['|','|',('journal_entry_ids', '=', []), ('state', '=', 'confirm'),('type', '!=', 'bank')]}"/>
</xpath>

顺便说一下，你重复相同的xpath两次，这对于Odoo来说是混乱和慢的，所以我把它分成一个更有意义的。
