在 Odoo 中创建动态视图会破坏 MVC
Creating a dynamic view in Odoo breaks MVC
一段时间以来，我一直试图找出如何进行条件视图继承，即仅在满足条件时才修改视图。
继承的视图如下：
<record id="invoice_tree_inherit" model="ir.ui.view">
<field name="name">account.invoice.tree.inherit</field>
<field name="model">account.invoice</field>
<field name="inherit_id" ref="account.invoice_tree" />
<field name="arch" type="xml">
<data>
<xpath expr="//tree" position="replace">
<tree create="true"
colors="blue:state == 'draft';black:state in ('proforma','proforma2','open');gray:state == 'cancel'"
string="Invoice" visible="false">
<field name="number" />
<field name="date_invoice" />
<field name="partner_id" groups="base.group_user" />
<field name="commercial_partner_id" invisible="0" />
<field name="reference" invisible="1" />
<field name="name" invisible="1" />
<field name="journal_id" invisible="1" />
<field name="period_id" invisible="1"
groups="account.group_account_user" />
<field name="currency_id" groups="base.group_multi_currency" />
<field name="amount_total" sum="Total Amount" />
<field name="amount_tax" sum="IVA" />
<field name="state" />
<field name="comment" />
<field name="type" invisible="context.get('type',True)" />
</tree>
</xpath>
</data>
</field>
</record>
但是我找不到一个令人满意的方法来让它继承视图，只有在满足条件的情况下。所以我选择了所描述的路线（在其他网站中）here.
我在 models.py 中编写的代码如下：
class Modulotest(models.Model):
_inherit = 'account.invoice'
def fields_view_get(self, cr, uid, view_id=None, view_type='form', context={}, toolbar=False):
result = super(Modulotest, self).fields_view_get(cr, uid, view_id, view_type, context=context, toolbar=toolbar)
if view_type=='tree' and result['name']=='account.invoice.tree':
currUtente=self.pool.get('res.users').browse(cr,uid,uid,context)
if currUtente.alt_view==True:
result['arch']=self.getAltView()
return result
def getAltView(self):
return '''
<tree create="true" colors="blue:state == 'draft';black:state in ('proforma','proforma2','open');gray:state == 'cancel'" string="Fattura" visible="false">
<field name="number" modifiers="{"readonly": true}"/>
<field name="date_invoice" modifiers="{"readonly": [["state", "not in", ["draft"]]]}"/>
<field name="partner_id" on_change="1" modifiers="{"readonly": [["state", "not in", ["draft"]]], "required": true}" string="Cliente"/>
<field name="commercial_partner_id" invisible="1" modifiers="{"readonly": true, "tree_invisible": true}"/>
<field name="reference" invisible="1" modifiers="{"tree_invisible": true}"/>
<field name="name" invisible="1" modifiers="{"readonly": [["state", "not in", ["draft"]]], "tree_invisible": true}"/>
<field name="journal_id" invisible="1" modifiers="{"readonly": [["state", "not in", ["draft"]]], "required": true, "tree_invisible": true}"/>
<field name="period_id" invisible="1" modifiers="{"invisible": true, "readonly": [["state", "not in", ["draft"]]], "tree_invisible": true}"/>
<field name="currency_id" invisible="1" modifiers="{"invisible": true, "readonly": [["state", "not in", ["draft"]]], "required": true, "tree_invisible": true}"/>
<field name="amount_total" sum="Importo Totale" modifiers="{"readonly": true}"/>
<field name="amount_tax" sum="IVA" modifiers="{"readonly": true}"/>
<field name="state" modifiers="{"readonly": true}"/>
<field name="comment" modifiers="{}"/>
<field name="type" invisible="context.get('type',True)" modifiers="{"readonly": true, "tree_invisible": true}"/>
</tree>
''';
class UtenteEsteso(models.Model):
_inherit = 'res.users'
alt_view=fields.Boolean("Vista alternativa", default=False)
这个解决方案工作得很好，但是视图的元素是在模型中给出的，这不是我喜欢的。它打破了MVC架构模式。
我想要的是以某种方式从 views 文件夹中的 xml 文件中检索此字符串，但到目前为止，我还没有找到导入 xml 文件（或多个文件）的好方法一般而言）来自 odoo API.
如果有人知道如何做到这一点，或者知道我可以实现相同效果的替代方法，而无需在模型中包含视图元素，我将不胜感激！
在您的模型文件中，此代码有效
class Modulotest(models.Model):
_inherit = 'account.invoice'
@api.model
def fields_view_get(self, view_id=None, view_type='form', toolbar=False):
def get_view_id(xid, name):
try:
return self.env.ref('account.' + xid)
except ValueError:
view = self.env['ir.ui.view'].search([('name', '=', name)], limit=1)
if not view:
return False
return view.id
result = super(Modulotest, self).fields_view_get(view_id, view_type, toolbar=toolbar)
if view_type == 'tree' and result['name'] == 'account.invoice.tree':
currUtente = self.env.uid
if currUtente.alt_view:
result['arch'] = get_view_id('invoice_tree_inherit', 'account.invoice.tree.inherit').id
return result
class UtenteEsteso(models.Model):
_inherit = 'res.users'
alt_view = fields.Boolean("Vista alternativa", default=False)
