Hello, We are a small startup producing organic food. I want to use Tryton in a for inventory management and later for accounting. In food and especially organic food it is essential to exactly track all the lots. In the stock.moves table is all the information needed, but i need a way to display the history of a specific lot in the sense of what lots were used to produce it and what lots were used to produce them and so on until the shipment the ingredients came with. So it is going to be a big tree, that is not possible to know before. After quite a lot of reading, i see three possibilities to approach the problem: 1. owerwriting table_querry() in a new ModelSQL: i could join several tables to have all relevant information in one model, but i have to filter the records in steps and in each step finding the parents of the curent lot, and only then i can start finding the grandparents. I don't know how to filter the table with in such a way, witch is (i think so) not possible with a Domain or a where-clause. 2.overwriting read() in a new ModelStorag: i was reading about this possibility in the mailing-list (https://www.mail-archive.com/[email protected]/msg06049.html). This way I can build the list of records as i need it. But read() gets ids as an argument, and i don't know were the ids come from. And before the read() is called and the tree is build, it is impossible to know how many records will be there. Is it possible to use the read() method anyway ignoring ids? 3. using babi or hebi could perhaps solve my problem. But these are quite complex modules with little documentation, so it would be nice to get a hit from insiders whether it is worth diving into (and witch of them) to get a solution. See babi_* modules that add some default reports to know how to do new/custom reports. This is what i found so far, but perhaps there other possibilities i don't know of?
