Disable Create button in Tree view but keep Import
I need to create a new View which can´t be editable and the button Create has to be disabled, but the Import should stay.
With create = "false" the import option is disabled too, is there any option to keep it or I need to create a new button which makes the same action?
I use Odoo 8.
<record id="historic_quote_sale_order_tree_view" model="ir.ui.view">
<field name="arch" type="xml">
<tree string="Historic Sale Form" create="false" edit="false">
Thanks in advance.
