I try to migrate the module https://www.odoo.com/apps/modules/10.0/product_default_image/ to Odoo 11.0.

Based on this post (https://www.odoo.com/forum/help-1/question/how-can-i-add-default-image-to-wizard-104874) I have changed the code as follows:

product_image = fields.Binary(
        string='Global Product Image',
        default=lambda s: s._default_product_image(),
        help='Use as the global image for all product default images. '
             'Limited to 1024x1024.',
    )

    @api.model
    def _default_product_image(self):
        image_path = get_module_resource(
            'product_default_image', 'static/src/img', 'glob_prod_img.png'
        )
        with open(image_path, 'rb') as handler:
            image_data = handler.read()
        return tools.image_resize_image_big(image_data)

But now I get the following error:

Error:
Odoo Server Error

Any idea on how to solve this?

Hi Ermin,

I believe it is failing at your end because you don't read the base64 encoded content of the file. This example works for me and I have it running on a few of my instances:

def _get_default_image(self):
    with open(modules.get_module_resource('product_default_image',
    'static/src/img',
    'glob_prod_img.png'),
    'rb') as f:
        return base64.b64encode(f.read())

custom_image = fields.Binary(string='Image', default=_get_default_image)

Regards,
Yenthe

Hi Yenthe,

Thank you very much for your answer.

This is the new code I have based on your answer:

product_image = fields.Binary(
        string='Global Product Image', 
        default=_get_default_image,
        help='Use as the global image for all product default images. '
             'Limited to 1024x1024.',
    )

    @api.model
    def _get_default_image(self):
        with open(modules.get_module_resource('product_default_image', 
        'static/src/img', 
        'glob_prod_img.png'), 
        'rb') as f:
            return base64.b64encode(f.read())

But the error message now is:

    string='Global Product Image', default=_get_default_image,

How can I fix that?

Put the function above the field definition and it'll work. Default methods have to be above the field definition in order to work :) I've modified my answer too as it might confuse others.

I was thinking about that :-)

Thank you very much !
