Odoo 8 open treeview from wizard

Question

I have a wizard that research and add the result to a table and I created a treeview that read the items in this table. I want my wizard to open that treeview once the research is done but I can't find a way to redirect to a specific view from python. Anyone have an idea?

My module is called sale_recherche_client_produit

All my files are at the root of my project folder

My main python file (sale_recherche_client_produit_wizard.py)

Answer 1

Suppose there is one button in wizard when you click on that button it will open tree view of particular model.

In wizard button should looks like,

<button class="oe_inline oe_stat_button" name="open_tree_view"  type="object" icon="fa-pencil"> Open Tree View
</button>

And in py method should looks like,

@api.multi
def open_tree_view(self):
    self.ensure_one()
    treeview_id = self.env.ref('external_id_of_treeview').id
    return {
        'name': 'Title',
        'type': 'ir.actions.act_window',
        'view_type': 'form',
        'view_mode': 'tree,form',
        'res_model': 'model.name',
        'views': [(treeview_id, 'tree')            
        'target': 'current',
        'domain' : [('id','in',search_ids)],
        ### in domain pass ids if you want to show only filter data else it will display all data of that model.
    }
