How to efficiently build product model with subcomponent list in django application
I am developing a product catalog web application that consists about 100 of main products build from 15-25 subproducts. Subproduct catalog is much larger, as there are almost 500 different components to build the main products. Subproducts are also multi-layer builds. Components should be stored to sqlite database and data should be reachable by the product id to create some packaging documentation, boms and other lists. I haven't really found any good examples that I could apply to this problem as making lists like this doesn't seem to be as easy as I thought it would. Does anyone know any examples that would be helpful to case like this? -
