I have in my model function filed returning binary. How can I change returning filname?

Function:

def _get_vcard(self, cr, uid, ids, prop, unknow_none, context=None):
            res = []
            for id in ids:
                res.append((id, base64.b64encode("test".encode('utf-8'))))
            return dict(res)

Model:

 _columns = {
        'vcard': fields.function(_get_vcard, type='binary', string='vCard')
    }

Hi, try to use something like this:

py file:

_columns = {
    'vcard_stream': fields.binary('File Stream', readonly=True),
    'vcard_name': fields.char('File name', 40, readonly=True),
}

_defaults = {
    'vcard_name': 'your_filname.vcard',
}

xml file:

<field name="vcard_stream" string="File Stream" filename="vcard_name"/>

Hi Alexandar, I followed the same steps in my custom module but download file name always shows Model name used in the xml File For example Download file name shows "model_name" <field name="model">model.name</field> Not downloaded with defined _defaults file name. Any idea? How to fix this issue. Thanks

Alexander

Hi. Can you show your source code? Perhaps you missed something.

Prakash

Updated the source code

I have also done the same thing above, but I did not get the result. The name is shown as a pdf extension but, it is downloaded/opened as binary file which has no extension. How we can embedd the extension along with the file generation?

Sarender Reddy

Use like below in xml file.

as per Odoo11

<field widget="binary" name="datas" filename="datas_fname"/>

<field name="datas_fname" readonly = "1" invisible="1" force_save="1"/>

Get the uploaded file in py file.

curr_obj = self

if not curr_obj.datas:

raise UserError(_('Please Choose The File!'))

file_name = curr_obj.datas_fname

print "curr_obj.datas_fname here",curr_obj.datas_fname

print "file namr here",file_name

fname = str(file_name.split('.')[1])

if fname != 'xls':

raise UserError(_('Please Choose The File With .xls extension and proper format!'))

try:

val=base64.decodestring(curr_obj.datas)

fp = StringIO.StringIO()

fp.write(val)

wb = xlrd.open_workbook(file_contents=fp.getvalue())

wb.sheet_names()

sheet_name=wb.sheet_names()

sh = wb.sheet_by_index(0)

sh = wb.sheet_by_name(sheet_name[0])

n_rows = sh.nrows

Hi Vitaly!

The answer posted by Prakash should work fine, i would just change this part

<group>
<field name="edi_filename"/>
<field name="edi_data" filename="edi_filename"/>
</group>

<group>
<field name="edi_filename" invisible='1'/>
<field name="edi_data" filename="edi_filename"/>
</group>

Because filename already shows up following Download in your view and as this is "readonly" you do really need to display it two times.

But with the code you're showing above i am not sure if the previous answers reached your expectation.

I advise you to go to have a look on the ir.attachment model in the Base module of odoo. You will find all the answer you want to find there.

However, you will indeed need a field filename in order to have a name (plus an extension?) to your downloaded file.

Prakash

In Wizard using the below code

Python File

_columns = {
        'edi_data': fields.binary('File Stream', readonly=True),
        'edi_filename': fields.char('File Name', size=32, readonly=True),
        }



_defaults = {
   'edi_filename': 'Invoice.txt',
 }

XML File

<field name="arch" type="xml">
            <form string="Form">
                <group>
                    <field name="edi_filename"/>
                    <field name="edi_data" filename="edi_filename"/>
             </group>

Alexander

As far as I know "name" is something like function word. Try to rename fields. Also _defaults = { 'name': 'Invoice.txt', } should be in py file.

Alexander

I don't know. My example works. Try to use it without any changes first. Maybe _stream and _name are "magic" words.

Prakash

Can you please post your web\controllers\main.py File saveas_ajax Method code i think in my case issues in that file. I am using latest version 7 but still issues. Thanks

Abhishek H Menon

In my case, it is a wizard which has a readonly binary field for storing file, and I am getting the file, but when I suppose to download it, it is getting downloaded as a binary file which has no specific extension. I need the file in pdf. Can anyone please suggest a way to do that?
