Hi friends,

Im working in odoo8.I have wrote a default function to returns invoice ID's to one2many, based on condition.in tree view of one2many it shows customer tree view instead of supplier invoice tree view.How can i change that to supplier invoice tree view.Here i given my code for the reference:

class project_usage_wizard(osv.osv_memory):

_name = 'project.usage.wizard'

_description = 'Project Used Quantity'

_columns = {

'project_id': fields.many2one('project.project', 'Project'),

'budget_id': fields.many2one('boq.info.line','Budget'),

'budget_invoice_ids': fields.one2many('account.invoice', 'invoice_id', 'Invoice',),

'budget_receipt_ids': fields.one2many('account.voucher', 'voucher_id', 'Purchase Receipts'),

}

below function returns ids of invoice to one2many:

def default_get(self, cr, uid, fields, context=None):

account_obj = self.pool.get('account.invoice')

voucher_obj=self.pool.get('account.voucher')

if context is None:

context = {}

res = super(project_usage_wizard, self).default_get(cr, uid, fields, context=context)

line_list = []

vals = []

v_vals=[]

res_ids = context and context.get('active_ids', [])

budget_obj = self.pool.get('boq.info.line')

budget = budget_obj.browse(cr, uid, res_ids, context=context)

project_obj = self.pool.get('project.project')

project_id = project_obj.browse(cr,uid,budget.project_id.id, context=context)

account_line_obj=self.pool.get('account.invoice.line')

line_ids = account_line_obj.search(cr,uid,[('budget_line_id','=',budget.id)])

for inv in account_line_obj.browse(cr,uid,line_ids):

    print "inv",inv

    account_ids = account_obj.search(cr,uid, [('id','=',inv.invoice_id.id),('state','in',('open','paid'))])

    print "account_ids",account_ids

    if account_ids:

        for invoice in account_obj.browse(cr,uid,account_ids):

            vals.append(invoice.id)

            res.update(budget_invoice_ids=vals)

# for purchase receipts

budget_obj = self.pool.get('boq.info.line')

budget = budget_obj.browse(cr, uid, res_ids, context=context)

project_obj = self.pool.get('project.project')

project_id = project_obj.browse(cr,uid,budget.project_id.id, context=context)

voucher_line_obj=self.pool.get('account.voucher.line')

v_line_ids = voucher_line_obj.search(cr,uid,[('budget_line_id','=',budget.id)])

for voucher in voucher_line_obj.browse(cr,uid,v_line_ids):

    print "voucher",voucher

    voucher_ids=voucher_obj.search(cr,uid, [('id','=',voucher.voucher_id.id),('state','=','posted')])

    if voucher_ids:

         for v_ids in voucher_obj.browse(cr,uid,voucher_ids):

            v_vals.append(v_ids.id)

            res.update(budget_receipt_ids=v_vals)

return res
