Composite primary key - N:M relationship - reader problem

[javaman]

I have a table that have a composite primary key.

How can I do a reader with that?

I found this thread about that.
I want to know, is there a better solution for that?

I search on api and examples and didn't find anything about it.

nobody?

That solution was only to get the correct id. If you don't care about the id value you can also have it auto-generate (don't specify an id or idProperty/idIndex).

There's also a patch floating around that modifies getJsonAccessor so it accepts functions (so you can build any id you want).

Thanks Condor.

But I really need the ID.

The table has 2 id's, from another 2 tables.
So, I need the id's to update the values in the correct registry.

I think the only solution is that you have explained in the other thread, correct?
Is there a better one?

And at my controller, I have to separate the id's that are posted, right?

Another thing, i searched about getJsonAccessor and didn't find anything about on api.
What's is that?

Do you really need an id? I think you only need 2 fields with the id values.

ps. getJsonAccessor is a private method of JsonReader, so it isn't documented.

[javaman]

Hum, right condor!

I was thinking about the id's that I just forget that I can post then as simple fields....

Thanks condor!

Thread resolved!

Just one more thing, the method getJsonAccessor do what?
I searched on forum and found some threads with that but I didn't understeand what it does.

As my understanding the JsonAccessor does the mapping.

[Condor]

It's used to convert a mapping to a function that retrieves the data from the JSON object, e.g.

mapping: 'myfield'

is converted to:

function(o){return o['myfield'];}

Ok, thank you!

Now, thread really resolved!
