我试图创建一个新的向导，我对如何做到这一点并不了解:( 在某些指南中，我找到了这段代码：
<wizard
id="test_wizard"
keyword="client_action_multi"
model="product.product"
name="product.product.product_id"
string="Test wizard" />
在技术纪念品中我发现了这个：
<record id="action_idea_cleanup_wizard" model="ir.actions.act_window">
<field name="name">Cleanup</field>
<field name="type">ir.actions.act_window</field>
<field name="res_model">idea.cleanup.wizard</field>
<field name="view_type">form</field>
<field name="view_mode">form</field>
<field name="target">new</field>
</record>
我应该使用哪种语法？
python文件：
from openerp.osv import osv
from openerp.osv import fields
class create_ean(osv.osv_memory):
_name='generate.ean'
_columns = {
'product_def_code' : fields.text('Product Default Code'),
'product_gen_code' : fields.text('Product Generated EAN13', readonly = True),
}
#defaults calls a function that will browse your main object and fill the field with the existing information
_defaults = {
'product_def_code': lambda self, cr, uid, context: self._get_product_id(cr, uid, context),
'product_gen_code': lambda self, cr, uid, context: self.generate_ean(),
}
def save_code(self, cr, uid, ids, context=None):
if 'active_id' in context:
info = self.browse(cr,uid,ids)
self.pool.get('ean13').write(cr,uid,context['active_id'],{'ean13': info[0].product_gen_code})
return {
'type': 'ir.actions.act_window_close',
}
def generate_ean(self):
return "ouhdeguosAB13"
def _get_product_id(self, cr, uid, context=None):
if 'active_id' in context:
return self.pool.get('product.product').browse(cr, uid, context['active_id'], context).product_id
create_ean()
XML文件：
<?xml version="1.0" encoding="utf-8"?>
<openerp>
<data>
<!-- create a view with a unique id -->
<record id="view_generate_ean13_code_wizard" model="ir.ui.view">
<field name="name">generate_ean13_code.form</field>
<field name="model">product.product</field>
<field name="type">form</field>
<field name="arch" type="xml">
<!-- create a normal form view, with the fields you've created on your python file -->
<form string="Insert reformulation info" version="7.0">
<group >
<separator string="EAN13 Code Generator" colspan="2"/>
<field name="product_def_code" string="Product Default Code"/>
<field name="product_gen_code" string="Product EAN13 Generated Code"/>
<newline/>
</group>
<div style="text-align:right">
<button icon="gtk-cancel" special="cancel" string="Cancel"/>
<button icon="gtk-ok" name="save_code" string="Save the code" type="object" />
</div>
</form>
</field>
</record>
<!-- your action window refers to the view_id you've just created -->
<record id="action_generate_ean" model="ir.actions.act_window">
<field name="name">Generate EAN13</field>
<field name="type">ir.actions.act_window</field>
<field name="res_model">generate.ean</field>
<field name="view_type">form</field>
<field name="view_mode">form</field>
<field name="view_id" ref="view_generate_ean13_code_wizard"/>
<field name="target">new</field>
</record>
<act_window id="action_generate_ean"
name="Generate EAN13"
res_model="generate.ean"
view_mode="form"
target="new"
/>
</data>
</openerp>
我将解释我需要做什么，基本上我需要采取产品的product_id，并且我生成ean13，我做了一个测试方法来生成代码，但我不明白将生成的代码保存在ean13字段中以及如何使用my方法通过传递product_id来生成该代码

关于向导的文档有点不清楚，我（仍然）有一些难以理解它是如何工作的，但我会在这里留下一个带有文本字段的工作向导的示例，它保存到一个调用对象（你必须改变表的名称以使其适应你的需要。）
创建一个python文件，如：
from openerp.osv import osv
from openerp.osv import fields
from openerp.tools.translate import _
class ref_generic_request(osv.osv_memory):
# create a table in osv_memory, with the columns you need
# to fill in your wizard
_name = 'ref.generic.request'
_columns = {
'reformulation_info': fields.text(
'Reformulation instructions',
help='Instructions for the requestor justification the reformulation needs'),
}
# create a function that will save the info from your wizard into
# your model (active_id is the id of the record you called the wizard
# from, so you will save the info entered in wizard in that record)
def save_info(self, cr, uid, ids, context=None):
if 'active_id' in context:
info = self.browse(cr, uid, ids)[0].reformulation_info
gen_req = self.pool.get('generic.request')
gen_req.write(
cr, uid, context['active_id'],
{'reformulation_info':info, 'needs_reformulation':1}
)
return {'type':'ir.actions.act_window_close'}
ref_generic_request()
然后创建视图以显示向导：
<?xml version="1.0" encoding="utf-8"?>
<openerp>
<data>
<!-- create a view with a unique id -->
<record id="view_reformulate_generic_request_wizard" model="ir.ui.view">
<field name="name">reformulate_generic_request_wizard.form</field>
<field name="model">ref.generic.request</field>
<field name="type">form</field>
<field name="arch" type="xml">
<!-- create a normal form view, with the fields you've created on your python file -->
<form string="Insert reformulation info" version="7.0">
<group >
<separator string="Please insert instruction for the reformulation of this request" colspan="2"/>
<field name="reformulation_info" string="Reformulation info"/>
<newline/>
</group>
<div style="text-align:right">
<button icon="gtk-cancel" special="cancel" string="Cancel"/>
<button icon="gtk-ok" name="save_info" string="Send to reformulation" type="object" />
</div>
</form>
</field>
</record>
<!-- your action window refers to the view_id you've just created -->
<record id="action_reformulate_generic_request" model="ir.actions.act_window">
<field name="name">Reformulate Request</field>
<field name="type">ir.actions.act_window</field>
<field name="res_model">ref.generic.request</field>
<field name="view_type">form</field>
<field name="view_mode">form</field>
<field name="view_id" ref="view_reformulate_generic_request_wizard"/>
<field name="target">new</field>
</record>
<act_window id="action_reformulate_generic_request"
name="Reformulate Request"
res_model="ref.generic.request"
view_mode="form"
target="new"
/>
</data>
</openerp>
编辑 - 您可能希望使用向导来更新已存储在数据库中的信息，为此您必须进行搜索并在其中加载包含此信息的向导。这就是我这样做的方式（不确定它是否是最好的方式，我会留在这里也许有人会评论一下它是正确的！）
class review_opinion(osv.osv_memory):
_name='review.opinion'
_columns = {
'opinion_emission': fields.text('Opinion emission'),
'notes': fields.text('Additional notes'),
}
#defaults calls a function that will browse your main object and fill the field with the existing information
_defaults={
'opinion_emission': lambda self, cr, uid, context: self._get_opinion(cr, uid, context),
'notes': lambda self, cr, uid, context: self._get_notes(cr, uid, context), # populates requestor field with actual user id
}
def save_info(self, cr, uid, ids, context=None):
if 'active_id' in context:
info = self.browse(cr,uid,ids)
self.pool.get('opinion').write(cr,uid,context['active_id'],{'opinion_emission': info[0].opinion_emission,'notes': info[0].notes})
return {
'type': 'ir.actions.act_window_close',
}
#functions that get the info stored in db
def _get_opinion(self, cr, uid, context=None):
if 'active_id' in context:
return self.pool.get('opinion').browse(cr, uid, context['active_id'], context).opinion_emission
def _get_notes(self, cr, uid, context=None):
if 'active_id' in context:
return self.pool.get('opinion').browse(cr, uid, context['active_id'], context).notes
review_opinion()
