如何在odoo中的另一个模型中调用qweb报告？

Question

I have created a wizard in the that using many2one field of another model. where the qweb-report has been mentioned. Now I want to select 1record(from many2one field) and print the respective report.[previously i've done invoice printing in that menu's form view.] . sometimes here empty report is getting prints.Can anybody please explain it clearly?here is my code.

class invoice_wizard(osv.TransientModel):
_name = 'invoice.wizard'

_columns = {

    'name':fields.many2one('hotel.booking',string="CustomerName"),

    }

def invoice_print(self,cr,uid,ids,vals,context=None):
    bookz=self.browse(cr,uid,ids,context=context)
    ids2=self.pool.get['book.room'].search([('name','=',bookz.name.name)])


    data = {
        'ids': ids2,
        'model': 'book.room',
        'form': self.env['book.room'].read(['name'])[0]
    }

    return self.env['report'].get_action(self, 'hotels.Booking_Details',
                                         data=data)

invoice_wizard()  

I'm getting this error:

Answer 1

You can try this code:

class invoice_wizard(osv.TransientModel):
_name = 'invoice.wizard'

_columns = {

    'name':fields.many2one('hotel.booking',string="CustomerName"),

    }

def invoice_print(self,cr,uid,ids,vals,context=None):
    bookz=self.browse(cr,uid,ids,context=context)
    ids2=self.pool.get('book.room').search([('name','=',bookz.name.name)])


    data = {
        'ids': ids2,
        'model': 'book.room',
        'form': self.env['book.room'].read(['name'])[0]
    }

    return self.env['report'].get_action(self, 'hotels.Booking_Details',
                                         data=data)

invoice_wizard()  

If you use self.pool then write self.pool['module name'] and if you use self.pool.get then self.pool.get('module name')

May be this is help you.

Answer 2

class report_wizard(osv.TransientModel):
_name='report.wizard'
_columns={
    'room1':fields.many2one('hotel.allroom','roomnum','Room No.')
}
def print_report(self, cr, uid, ids, context=None):
    current=self.browse(cr,uid,ids)
    obj=self.pool.get('hotel.book')
    k=obj.search(cr,uid,[('room','=',current.room1.roomnum)],context=context)

    context = {}

    data = self.read(cr, uid, ids)[0]


    datas = {
    'ids': k,
    'model': 'report.wizard',
    'form': data,
    'context':context
    }
    return{
        'type' : 'ir.actions.report.xml',
        'report_name' : 'hotels.Booking_Details',
        'datas' : datas,
        } 

report_wizard()
