HABTM-Relation : Create a relation for all other records?

You should look into the Cake Has-And-Belongs-To-Many (HABTM) relationships. Check the cake book. It will allow you to create a relationship between two tables, using a join table, and will automatically retrieve and save values as requested in your application.

You should look into the Cake Has-And-Belongs-To-Many (HABTM) relationships. Check the cake book. It will allow you to create a relationship between two tables, using a join table, and will automatically retrieve and save values as requested in your application.

Please note, however, that from one model you cannot (by default) filter by criteria on the related model (in this case, the model related by the join table). To do this, you will need to use the Containable behavior, which will allow you to set filter criteria on the related tables. The one other caveat is that I don't know of a way (out of the box) to add some information about the relationship in the join table.

For example, if you wanted to record (in the join table) whether the user has completed the task, you would have to write your own stuff there. I usually get around this by creating a model for the join table, which I then invoke whenever I want to retrieve data specific to the joined relationship. By doing it this way, you can also easily pull up the data from the joined tables.

Anybody else have a better solution?

I am already familiar with the principles of HABTM relations and how to deal with them in cakephp. I asked for a way to process a large number of new relations without running out of cache. – Benedikt R.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
