ClassModelList::updateXref()

Deprecated

Please use the Relations instead.


This function is used to automate the links creation and destruction with simplified command.

After saving an item, if the POST query has sent more datas concerning relations with other tables, this function must be called.
The builder is for the moment not making reference to it, but the N:M tutorial is mentioning it.


N:M Use (many-to-many)

The links are database rows.
This function will insert or delete rows in database.

ClassModelList::updateXref N:M Cook

This following example is written in traveller (item) model:


N:1 Use

Foreign Keys are widly used in Cook, but what happen when we want to set up those links from the opposite side ?
This will be the use of N:1

The links are made with simple foreign keys in opposite table.
This function will only update or reset the concerned foreign keys values.

ClassModelList::updateXref N-1 Cook

This following example is written in country (item) model

Great UX great performance and definitely a time saver. It only took me 10 minutes of playing around before purchasing a subscription and right now I just want to throw more money at you! I just started a new project and after just 4h I can already tell it probably saved me several days of work. I'm building a wholesale ordering system with sales rep management. I have not looked at the code yet but so far: impressive.
