schema error mean app

Question

I have a schema problem. I dont get the right schema in my api. here is my api :

var Meetup = require(\'./models/meetup\');

    module.exports.create = functio

If req.body is undefined (as you wrote in the comments) then obviously new Meetup(req.body); cannot populate the new objects with any data (like {name: 'Text input'} or anything else) since it is called with undefined as an argument.

Make sure you use the body-parser and that you pass the correct data in your request.

Also, check for errors. Every callback that takes the err argument should be in the form of:

module.exports.list = function (req, res) {
  Meetup.find({}, function (err, results) {
    if (err) {
      // handle error
    } else {
      // handle success
    }
  });
}

How to track the problem:

• make sure you use the body-parser on the backend
• make sure you pass the correct data on the frontend
• make sure that the data passed by your frontend is in the correct place (body)
• make sure that the data is in the correct format (JSON? URL-encoded?)
• add console.log(req.body) after new Meetup(req.body); to know what you save
• open the Network tab in the developer console of your browser and see what is transferred
