    1. COThanks for the answer! The reason why I think it should be done server-side is simply because there's too many rules and they actually change often. So leaving them in the app would be a bit hard to manage if I need to change something. Ideally only some fields would be editable, like X quantity, and if the user does this, then I automatically update Y to be double. I was even thinking storing the js text of each function in the db, if the product had some rules. and when you bring the product, it would bring this "rule" field,bring the text and somehow convert it into actual code to validate.

    2. COIf the rules are so complicated that you want to store the entire functions, then I understand. I still think you should have validations in the models though, otherwise it can always be avoided. Instead of my approach with static ratios in the models, you could add another model called Rule which belong_to Product or even polymorphic associations to whatever model is in need of rules. That way the rules can be made dynamically but it still validated server side

    3. COHow would this work when an application is in production? If I did have this model as you described, would this mean if one rule changes, I need to redeploy the entire app? (Let's say I have easy access to the server as it would be mine) would it be a matter of just changing one file in the system or much more complicated than that?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
