Hello,

Please have a look on the complete blog "How to Download any File on Button Click".

I am sure that it will help a lot.

Thanks.

 Hello, u managed to solve this problem? kindly share with me how u solved it. i had the same problem but still did not able to solve it. thank you.

def get_contract_template(self):

    url = str('/madel_name/static/src/xls/template.xlsx')

    return {'type' : 'ir.actions.act_url','url': url,'target': 'self','tag': 'reload', }

You need to create a computed binary field. On the property compute assign the name of the function that calculates the field value of this field. '_compute_field' in this example.

@api.one
def _compute_field(self):   
   r = open(filename, 'rb').read().encode('base64')
   self.computed_field = r

Hi, this is one more option. On clicking the "Generate Excel" button, you can open a wizard, which contains a button "print xls" (and possibly some entries to pass to the report parser if needed), on that button call a python method, which is defined on the transient model, for eg:

- this is my button on wizard:

<button icon="gtk-execute" name="get_report" string="Export xls" type="object" context="{'xls_export':1}"/>;

- the method in transient model, in my case I have both pdf or excel report, thats why am passing context in button:

    @api.v7
    def get_report(self, cr, uid, ids, context=None):
        if context is None:
            context = {}
        data = {}
        data['ids'] = context.get('active_ids', [])
        data['model'] = context.get('active_model', 'ir.ui.menu')
        data['form'] = self.read(cr, uid, ids, ['pricelist_type',  'hek', 'pek', 'dek'], context=context)[0]
        
        if context.get('xls_export'):
            return {'type': 'ir.actions.report.xml',
                    'report_name': 'product.pricelist.xls',
                    'datas': data['form']
                    }
        else:
            return self.pool['report'].get_action(cr, uid, [], 'custom_module.report_pricelist', data=data, context=context)

then you just need to create one .py file containing the parser and code to generate the excel report. In my case I want to generate excel report of the products pricelist. I suppose you have the parser and code to generate xls. If you don't have, I can send you the code for reference, by email.

Hope this helps you.
