  }
});

Create a new post

var toSave = {
  title: req.body.title,
  post: req.body.post
};

db.post(toSave, function(error, posted) {
  if(error) {
    console.log(error);
  } else {
    console.log(posted);
  }
  res.redirect('/');
});

Get a single post

db.get(req.params.id, function(error, found) {
    if(error) {
      console.log(error);
      res.redirect('/');
    } else {
      res.render('show-post', { post: found });
    }
  });

  }
});

Update a post

var toSave = {

    res.redirect('/');
  } else {
    db.put({
      _id: found._id,
      _rev: found._rev,
      title: req.body.title,

db.get(req.params.id, function(err, found) {
  if(err) {

      if(err) {
        console.log(err);
