Validate array of objects?

When I submit a single object as my payload I can validate keys very easily with:

req.checkBody('year', 'invalid year').len(4,4).isNumeric();

But I would like to submit an array of objects and loop through them with something like:

_.each(self.req.body, function(element, index, list) {
    req.checkBody([index].year, 'invalid year').len(4,4).isNumeric();
});

I’ve also tried using req.assert with element.year and even element.year.toString() with no luck.

What am I doing wrong? Or is this type of functionality even possible?

@rustybailey @gustavohenke @IOAyman I don’t think this is same issue as #125.

I think the OP was asking what if the req.body is an array of objects itself.

Example JSON -

[
    {"name": "Abc"},
    {"name": "Def"}
]

How do I begin to validate this. What argument do I provide to req.checkbody() because I want to validate the body itself. I want to do something like req.checkBody().isArray().

I used Wildcards in this situation and worked well.

array_of_objects:

[
  { name: 'something', value: 'anything'},
  { name: 'something', value: 'anything'},
  { name: 'something', value: 'anything'}
]

Validate array items: check('array_of_objects[*].*').trim().isLength({ min: 1, max: 10 }) etc.
