Can't pass test 5 and 6 of APIs and Microservices Projects - Exercise Tracker

[dat192001]

Hi Campers,
I am having the issue that my code to get ‘exercise log’ of user failed though I have tried all the condition I can think of. I have compared the output of the sample project and the output of mine and I still can’t figure out what’s the problem with my code.

This is my code so far

app.get('/api/exercise/log', (req, res) => {
  let userId = req.query.userId;
  let from = req.query.from;
  let to = req.query.to;
  let limit = req.query.limit;
  User.findOne({_id: userId}, {'log._id': 0}, (err, user) => {
      if (err) {
        console.error(err);
      }
      
      if (user) {
        let log = user.log.slice();

        if (from) {
          log = log.filter(exercise => new Date(exercise.date).getTime() >= new Date(from).getTime());
          from = new Date(from).toDateString();
        } 
        if (to) {
          log = log.filter(exercise => new Date(exercise.date).getTime() <= new Date(to).getTime());
          to = new Date(to).toDateString();
        }
        if (limit >= 1) {
          log = log.slice(0, limit);
        }

        if (from && !to) {
          res.json({
            '_id': user.id,
            'username': user.username,
            'from': from,
            'count': log.length,
            'log': log
          });
        } else if (to && !from) {
          res.json({
            '_id': user.id,
            'username': user.username,
            'to': to,
            'count': log.length,
            'log': log
          });
        } else if (from && to) {
          res.json({
            '_id': user.id,
            'username': user.username,
            'from': from,
            'to': to,
            'count': log.length,
            'log': log
          });
        } else {
          res.json({
            '_id': user.id,
            'username': user.username,
            'count': log.length,
            'log': log
          });
        }
      } else {
        res.send('unknown userId');
      }
    });       
});

This is my test output
Only userId:

userId with from condition:

userId with to condition:

userId with from and to condition:

userId with from, to and limit condition:

Hope that I can hear your response for my question soon. Thanks in advance!

Hello,

when using res.json to send a response, try using original javascript object syntax.

For instance do not do:

res.json({
            '_id': user.id,
            'username': user.username,
            'count': log.length,
            'log': log
          });

instead do this:

res.json({
            _id: user.id,
            username: user.username,
            count: log.length,
            log: log
          });

The reason for doing it this way is that res.json method will automatically convert Javascript object format into JSON format.

I believe you are wrapping your object keys in unnecessary double quotes.

Let me know if this fixes your problem.

Thanks for your response.
But I try to omit the quotes in the res.json but it still fails at these two tests

Post the link you’re trying to submit, screenshots are not too helpful.

This is my full project

My guess would be that the problem is in server.js on line 86:

  if (date === '') {

If date is not provided it’s not an empty string, it’s undefined.

OMG thank you it solved my problem. Even though till now I can’t understand why the problem is in test 4 but then it failed at my test 5 and 6.
Anyway, thank you so much again
