Hey guys, i need to share some of this with you.
When using the rest/api features in Yii, specifically the RestActiveController and you return a model with errors, it will prompt you the model errors in json/xml as:
[
{"field":"username","message":"Whatever"},
{"field":"password","message":"Whatever"},
]
And this is good for a single model, but what’s happening when we have to validate multiple models at once?
How do we go about this ?
Moreover, what happens if your main model has related models and they need to be subject to validation as well, and return nice structured error message, as in:
[
{
"some-model" : {
"errors": {
{"field":"username","message":"Whatever"},
{"field":"password","message":"Whatever"},
},
"some-child/related-model" : {
"errors": {
{"field":"username","message":"Whatever"},
{"field":"password","message":"Whatever"},
}
}
}
}
]
I didn’t see a way to return the errors in this way, or even closer.
Seems that everything the framework can do is to handle only single models, one at a time. Is this correct?
I don’t mind creating code for my specific use case, which i did anyway, but i want to make sure i don’t reinvent the wheel with this…
P.S: I know the json above is malformed, go with it 
Thanks.
