Hi there,

Thanks a lot for your work on Cook, this is an impressive component builder. Congratulations!

A question, please:
I would like to build a many-to-many relation between 2 tables. Is Cook able to design it? I didn't see anything about that in the builder, but only foreign keys (one-to-many relations).

Example:
I have 2 tables:
  1. 'Books' ('id', 'name', 'author')
  2. 'Tags' ('id', 'name')

Rule 1: A book can have none or several tags. Relation 0-n
Rule 2: A tag can be assigned to none or several books. Relation 0-n

How can I design this in Cook? Do I have to design an another table between these 2 tables?

Thanks for your answer.

Best.

Hi and welcome to the community !
Thank you for your review. Don't forget the JED.

About your question, it is not possible from the builder.

You can follow here :
www.j-cook.pro/forum/9-coding-inside-you...-3rd-level-item#6222

It has been treated several times on the forum.

...and you can try the tutorial (in french for the moment) :

Coding is now a piece of cake

Thanks Chief!

I'll have a look to this! :)
BTW, I'm french, so this is not a problem for the tutorials.

Best.

This is what you call a component builder. I was able to master using this in a very short time and the resulting component works like a charm. Not just a basic component builder but a fully working component builder with forms fields tables all ready to go. You can make the list and item views to display in the front and back end. Also there is a great forum just starting to evolve and I'm sure this will grow very rapidly when you all realise how good this tool is.
