All the attachments are stored on the \_ir.attachmen\_t model. The resource field is used as reference to the related method. So for getting all the attachments of a sale you have to perform a search on the _ir.attachment_ model filtering with the records that have _‘sale.sale,1’_ for the resorce field (replacing 1 with the id of the sale you want to read.

The same applies for product by using the correct method.

Just use the [search\_read](http://doc.tryton.org/4.2/trytond/doc/ref/models/models.html?highlight=read#trytond.model.ModelStorage.search_read) endpoint to read the data field and using  
[(‘resource’, ‘=’, ‘sale.sale,1’)] as [domain](http://doc.tryton.org/4.2/trytond/doc/topics/domain.html#topics-domain).

You have to create a ir.attachment record with the resource field referencing the record.
