Hi all,

I have been looking for a block of code that helps me to "resize a dynamic image" on the fly for both create and write methos with no luck.

All the code I found is for later versions and actually not performing well on Odoo 12 (or at least I am not changing the code as I should).

I found this code block under "fleet" management app on Odoo 12 which seems to be a very simple code to understand.

class FleetVehicleModelBrand(models.Model):
    _name = 'fleet.vehicle.model.brand'
    _description = 'Brand of the vehicle'
    _order = 'name asc'
    name = fields.Char('Make', required=True)
    image = fields.Binary("Logo", attachment=True,
        help="This field holds the image used as logo for the brand, limited to 1024x1024px.")
    image_medium = fields.Binary("Medium-sized image", attachment=True,
        help="Medium-sized logo of the brand. It is automatically "
             "resized as a 128x128px image, with aspect ratio preserved. "
             "Use this field in form views or some kanban views.")
    image_small = fields.Binary("Small-sized image", attachment=True,
        help="Small-sized logo of the brand. It is automatically "
             "resized as a 64x64px image, with aspect ratio preserved. "
             "Use this field anywhere a small image is required.")

    @api.model_create_multi
    def create(self, vals_list):
        for vals in vals_list:
            tools.image_resize_images(vals)
        return super(FleetVehicleModelBrand, self).create(vals_list)

    @api.multi
    def write(self, vals):
        tools.image_resize_images(vals)
        return super(FleetVehicleModelBrand, self).write(vals)

The code above seems to be very easy to undertand but:

On the class FleeetVehicleModelBrand, I have 3 image type fields, named image, image_medium and image_small.

On both create and write methods, I do not see any code that refers to those images itself. That is, I don't see any reference to the type of image that has to be resized.

Questions (UPDATED):

Note: I have updated the question(s) based on what I have done after the first post.

I found that the images have to be named exactly "image, image_medium and image_small) for the resizing work. Otherwise, fields on image type with different names will not be resized.

1. What if I have an image type field with a differente name? For instance, "student_picture"?

How can I resize this image?

I really hope you can help me with this issue because the code found on other modules (customer, products) are harder to understand and to adapt to my needs.

I need to resize images (to 1024x1024) using odoo standard tools on both create and write methods, for more than one field of type image.

Thank you in advance

Regards
