Test not passing when chaining helpers

JavaScript
#1

Tell us what’s happening:

Repl:https://repl.it/@akshitchaturved/boilerplate-mongomongoose
I’m following all the hints yet I’m unable to pass the test. Pls help me out.

Your code so far

var queryChain = function(done) {
  
  
 Person.find({ age: 55 })
  .sort({ name: -1 })
  .limit(5)
  .select({ favoriteFoods: 0 })
  .exec(function(error, people) {
    if(error){
       done(error);
    }
    
    done(null, people);
  })

Challenge: Chain Search Query Helpers to Narrow Search Results

Link to the challenge:

  1. You are not using foodToSearch for the .find()

  2. The default sort order is ascending, which I believe is what is expected.

  3. You are not limiting the results to two documents.

  4. You are not excluding the age.

I would suggest you look at the docs, for find and query.

#3

Thanks for the quick feedback. I’ve made the suggested changes but I am unable to pass the test.

var queryChain = function(done) {
  foodToSearch = "Chickpea"
  Person.find({favoriteFoods: foodToSearch}).sort({name:1}).limit(2).select({age:0}).exec(function(error, people) {
    if(error){
       done(error);
    }
    
    done(null, people);
  })
  
};

Why did you change the value of foodToSearch and why did you remove the declaration?

Edit: you should also keep the code format like it was, it’s really hard to read now.

#5

No value for foodToSearch was provided beforehand.I’ve been taught to use ‘var’ instead of ‘const’ (makes it more flexible). So, I changed the format.

#6

Yes, it was. Here is the starter code.

const queryChain = (done) => {
  const foodToSearch = "burrito";

  done(null /*, data*/);
};

Not sure who taught you that but I would unlearn that ASAP.

#7

I’ll use const from now on.

const queryChain = (done) => {
  const foodToSearch = "burrito";
  Person.find({favoriteFoods: foodToSearch}).sort({name:1}).limit(2).select({age:0}).exec(function(error, people) {
    if(error){
       done(error);
    }
    
    done(null, people);
  })
  
};

I still can’t pass the test. :frowning_face:

#8

Your code seems to be passing for me. Did you remember to restart the server?

#9

I restarted the server , still no luck.

#10

Not sure what is wrong.

When I take your code and put it in my own project it passes the test, if I fork your project and add my own .env file it passes the test.

Are you sure you are connecting to the DB correctly?
