HI

I'm with some troubles when I'm downloading some files. The name I set to the file is for example "123456.xml" and when I download it the file name is the name of my model....

I store the name and the filedata on a database to set as default on the new wizard after I click on a button (I have some images to help you understand :) )

My .py 

I create the columns 

class Saft_Export_Transporte(osv.osv_memory):
    _name = 'saft.export.transporte'
    _description = 'Saft Export'
    

 
    def get_filedata_transporte(self, cr, uid, context=None):
      cr.execute("SELECT filedata from Saft_Export_Transporte where id=1")
      output=cr.fetchone()
      output=str(output[0])
      return output

    def get_name_transporte(self, cr, uid,context=None):
      cr.execute("SELECT name from Saft_Export_Transporte")
      output=cr.fetchone()
      output=str(output[0])
      return output

    _columns = {
             'name': fields.char('Nome',size=25, readonly=True),
              'filedata': fields.binary('Texto',filters='*.xml'),
    }
    _defaults = {
            'filedata': get_filedata_transporte,
            'name': get_name_transporte
    }

My .xml

<record id="saft_export_transporte" model="ir.ui.view">
            <field name="name">Saft Export Transporte</field>
            <field name="model">saft.export.transporte</field>
            <field name="arch" type="xml">
                <form string="Saft Export Transporte" version="7.0">
                    <group col="1">

                    </group>
                    
                            
                    <footer>
            
                        <button string="Fechar" class="oe_link" special="cancel"/>
                    </footer>
