can't read push of undefined

Hello, I am struck at an error that says "can't read push of undefined ", Error is caused by line "Campgrounds.comments.push(comment)", I've talked with some people and they said that its a model, not a document blah blah, I didn't get anything. Any help would be appreciated :)

I will include Campgrounds and Comments code in comments section.

Here is the code:- 

function seedDB () {
    Campgrounds.remove({},function(err){
        if (err) {
            console.log(err);
        }    
        else {
            console.log("Removed All Camping Sites!");
            data.forEach(function(seed){
                Campgrounds.create(seed,function(err){
                    if (err) {
                        console.log(err);
                    }
                    else {
                        console.log("A Campground Has Been Successfully Added!");
                        Comments.create ({
                            title:"Really Great  Place, Definately worth it.",
                            author:"Chris"
                        },function(err,comment){
                            if (err) {
                                console.log(err);
                            }
                            else {
                                Campgrounds.comments.push(comment);
                                Campgrounds.save();
                                console.log("comment added");
                            }
                        });
                    }

                });
            });
        }
    });
}

This error is simply indicating that "Campgrounds" does not have an array property named "comments". The code that constructs "Comments" is not shown here, so the cause is not clear.

It's always good to show the complete code, or even better, make a snapshot of your workspace and post the link to it here. Providing a link to the relevant course page can be helpful also.
