    Comment Controller

  • ¶

    The comment controller handles requests passed from the comment router.

  • ¶

    The Q module is used to bind Mongoose methods to use promises.

    var Q = require('q');
var Comment = require('./commentModel.js');

module.exports = {
  • ¶

    Retrieve all of the comments for a given idea from the MongoDB database.

      allComments: function(req, res, next) {
  • ¶

    Bind the Mongoose find method to the Comment model, so that the Q module can use promises with it.

        var findAllComments = Q.nbind(Comment.find, Comment);
  • ¶

    Find all comments for a given idea. Send back the array of comments.

        findAllComments({idea_id: req.body.idea_id})
      .then(function(ideas) {
        res.json(comments);
      })
      .fail(function(error) {
        next(error);
      });
  },
  • ¶

    Add a new comment to the MongoDB database.

      newComment: function(req, res, next) {
  • ¶

    Bind the Mongoose create method to the Comment model, so that the Q module can use promises with it.

        var createComment = Q.nbind(Comment.create, Comment);
  • ¶

    Create a new document from the Comment model. If successfully created then the new Comment document is returned.

        var newComment = {
      text: req.body.text,
      idea_id: req.body.idea_id,
      created_by: req.body.created_by,
      created_at: req.body.created_at
    };

    createComment(newComment)
      .then(function (createdComment) {
        if (createdComment) {
            res.json(createdComment);
        }
      })
      .fail(function(error) {
        next(error);
      });
  }
