fetch relation preload documentation unclear

[giann]

Here's the paragraph

fetch relations can also provide a preloader to allow for the data to be loaded over an array of objects. The preloader function recieves as arguments: the array table of objects to preload, the current mode, the name of the relation.

• After trying it out: the third argument seems to be the model class and the fourth the name of the relation
• What's the current mode?

current mode should be current model

I updated the docs a bit, tell me if that helps at all

It’s better yes 👍 Maybe add the parameters in the snippets?
