sedouard / mongodb-mva Goto Github PK

Hi,
is a very great tutorial.

at the part you are changing /etc/mongod.conf file,
you have to execute vim with sudo right.
overwise, you can't save the file.

MongoDB Node.js Driver most probably updated, because when you try to get docs.length after inserting a document in callback function it return undefined in module 4 crud functionality. A little change is required as
"docs.ops.length" and the code changed respectively as
for(var i in docs.ops){
console.log(docs.ops[i].length);
}
docs in callback doesn't return a db object but a wrapper "ops" around that db object.

Given ..
db.bank_data.find({ accounts: { $elemMatch : { "account_type": {$ne: "Checking"}, "currency": "USD", 'account_balance' : { $gt: 9900000 } } } } ).sort({ accounts.account_balance: -1 })

db.bank_data.find({ 'accounts.account_balance': {$gt: 9000000}, 'account.currency': 'USD' })

should be.....

db.bank_data.find({ 'accounts.account_balance': {$gt: 9000000}, 'accounts.currency': 'USD' })

db.bank_data.find({ accounts: { $elemMatch : { "account_type": {$ne: "Checking"}, "currency": "USD", 'account_balance' : { $gt: 9900000 } } } } ).sort({ "accounts.account_balance": -1 })

Now - is not working for default installation
mongoimport "C:\Program Files\MongoDB\Server\3.0\bin\bank_data.json" --jsonArray --collection bank_data

Should be
mongoimport "C:\Program Files\MongoDB\Server\3.0\bin\bank_data.json" --jsonArray --db test --collection bank_data

I cloned your repository and when navigating with the command line to accomplish Step 1 of Module 3 (i.e. do the "npm install" piece) , I encountered "'npm' is not recognized as an internal or external command..." --- Is there another piece of the puzzle I missed? Thanks!

the mongodb default port is 27017 not 27107. If you insited on using 27107,would you please add a Warning or Note?
