[Sebastien Beau <sebastien.beau@xxxxxxxxxxxx>]

Hi all,

I worked on this during the last month and I need your feedback
https://code.launchpad.net/~akretion-team/server-env-tools/server-env-tools

The aim of my first module is to implement new kind of fields

BinaryField
ImageField
ImageResizeField


All of this fields will be store on the file system by default and not in
the
database. If you want to store it on an other support (database, S3, ftp,
SFTP...)
Then you should create your own 'storage class' and use your custom
'storage
class' instead

The default Storage class will store the field on the file system and build
the path like that

 BASE_LOCATION/DB_NAME/MODEL-FIELD/XXX/YYYYY

with

- BASE_LOCATION: the base location configured in ir.config_parameter
- DB_NAME:  your database name
- MODEL-FIELD: the concatenation of the name of the model with the name of
the
field, for example 'product_product-image'
- XXX: the first 3 letter of the file name build with their sha1 hash
- YYYYYY: file name build with their sha1 hash

Here is an example of field declaration

    'binary_test': fields.BinaryField('Test Binary'),
    'image_test': fields.ImageField('Test Image'),
    'image_test_resize': fields.ImageResizeField(
        related_field='image_test',
        string='Test Image small',
        height=64,
        width=64,
        ),



If you want to see to a real implementation take a look here :
http://bazaar.launchpad.net/~akretion-team/openerp-product-attributes/openerp-product-attributes-product-image/view/head:/product_image/product_image.py#L38


You can also try this module to understand better the way it work. (Note
resize field will be recomputed automatically as this field depend of
refernce field)

As you can see I have a custom path based on the model-field. I need this
because I want to serve some image directly from nginx without using
OpenERP/Odoo. If I use the same path for all of the binary/image then I
will be not able to choose what I want to share with nginx.


Hope this can help you.
