python - 工作流程按钮 Odoo v8

Question

我正在模块中执行工作流程，我已在 __openerp__ 文件中声明了工作流程 xml，执行了所有按钮功能，添加了 state 选择字段，并且在我看来还有statusbar，这是按钮功能之一:

def budget_validate(self,cr, uid, ids, context=None):

    if context is None:

        context = {}

    self.write(cr, uid, ids, {'state': 'validate'}, context=context)

    return True

就一个，因为无论我点击哪个，错误都是一样的，这是我的字段:

    state = fields.Selection([
        ('draft', 'Draft'),
        ('confirm', 'Confirm'),
        ('validate', 'Validate'),
        ('last', 'Last'),
        ('current1', 'Current1'),
        ('current2', 'Current2'),
        ('current', 'Current'),
        ('next', 'Next'),
        ('adjusted', 'Adjusted'),
        ('done', 'Done'),
    ], string="State", readonly=True, copy=False)

我的 View xml:

        <record id="view_order_form" model="ir.ui.view">
        <field name="name">account.budget.bsi.form</field>
        <field name="model">account.budget.bsi</field>
        <field name="arch" type="xml">
            <form string="Sales Order">
                <header>
                    <button string="Confirm" name="confirm" states="draft" type="object" class="oe_highlight"/>
                    <button string="Approve" name="validate" states="confirm" type="object" class="oe_highlight"/>
                    <button string="Last" name="last" states="confirm" type="object" class="oe_highlight"/>
                    <button string="Current 1" name="current1" states="last" type="object" class="oe_highlight"/>
                    <button string="Current 2" name="current2" states="current1" type="object" class="oe_highlight"/>
                    <button string="Current" name="current" states="current2" type="object" class="oe_highlight"/>
                    <button string="Next" name="next" states="current" type="object" class="oe_highlight"/>
                    <button string="Adjusted" name="adjusted" states="next" type="object" class="oe_highlight"/>
                    <button string="Done" name="done" states="adjusted" type="object" class="oe_highlight"/>
                    <button name="draft" states="cancel" string="Reset to Draft" type="object" class="oe_highlight"/>
                    <button string="Cancel Budget" name="cancel" states="confirm,validate" type="object" />
                    <field name="state" widget="statusbar" statusbar_visible="draft,confirm,last,current1,current2,current,next,adjusted,done,cancel" clickable="True"/>
                </header> ...

每次我点击任何按钮，它都会抛出我:

Traceback (most recent call last):

AttributeError: 'account.budget.bsi' object has no attribute 'validate'

最初，我将这些按钮设置为 type="workflow" 但在这种情况下，这些按钮不会执行任何操作。没有任何错误，但状态不会改变。

那么，有什么想法吗？

Answer 1

这就是我解决这个问题的方法:

@api.one
def budget_validate(self):
    self.write({'state': 'validate',})

保留 select 字段不变，并将按钮保留为 xml View 上的对象。
