Hello guys, I`m having one problem and i dont know what is it..

I`m using mongoose to fetch an array of posts to render my page.

loadPost : function *() {
      var posts = yield Post.find({url: this.params.post}).exec();

    yield this.render('blog/index', {
        'posts' : posts
    });
}

But, when i execute this code occurred this error

Sorry for my english, if someone can help me =D

It appears posts is a mongoose document which could potentially be a recursive data structure. In your call to render, try calling toObject() on posts. The code would look like below.

yield this.render('blog/index', {
  'posts': posts.toObject()
});

I just pushed a patch to npm that should handle recursive objects. Please try updating and let me know how it goes. You won't need the toObject() after updating.

Is this fixed for you?

I apologize for the delay. Worked perfectly, thank you very much = D
