Odoo: Download Binary File in v10

To download any binary file in Odoo10 following is the link:

http://127.0.0.1:8069/web/content?model=<module_name>&field=<field_name>&filename_field=<field_filename>&id=<object_id>

module_name   - the name of the model with the Binary field

field_name        - the name of the Binary field

object_id           - id of the record containing particular file.

field_filename   - name of a Char field containing file's name (optional).

So if you want to call a function on button click and download the file, code is as follow:

file_url = "http://127.0.0.1:8069/web/content?model=<module_name>&field=<field_name>&filename_field=<field_filename>&id=<object_id>"

return {

    'type': 'ir.actions.act_url',

    'url': file_url,

    'target': 'new'

}

In Reports or web page, you can use it as:

<t t-foreach="files" t-as="f">

    <tr>

        <td><t t-esc="f.name"/></td>

        <td><a t-attf-href="/web/content?model=<module_name>&field=<field_name>&filename_field=<field_filename>&id=<object_id>">Download</a></td>

    </tr>

</t>

Where files is a list of files
