using Mongo

So let's say for a simple example I have the database seed file from the Mongo Basics course which contains the DB name and the data which is then queried, managed updated in the Mongo shell.

Currently I have 2 locations where I'm currently attempting to run a Mongo project.

In once location I've gone a directory deeper than the data/db path

C:\data\db\Mongo-Projects\treehouse-mongo-basics

In there is the seed file.

So I then go to the Mongo shell and type

show dbs

And there's my database as created in my seed file.

var db = db.getSiblingDB('mongoBasics');

I can go into my project there and run any commands I want, right?

But then I go to my other location.

/c/users/pc2/documents/mongo/mongo-test

There's nothing there at the moment except an npm log file but I think I can start and run Mongo projects from here. If I go back into the Mongo shell from this location here and run show dbs again I get the same databases listed.

local        0.000GB
mongoBasics  0.000GB

The default local database and the mongoBasics database. How does this work? Is it best practice to store databases at a root folder in the c:/ or does mongo pick up on databases but still let you access them from any location?

You would start the Mongo daemon (mongod.exe) with the --dbpath option to use a data directory other than the default. Make sure you use the full path.

See the MongoDB documentation:

Thanks :)

I have a feeling though I'll be using the default location going forward. --dbpath isn't working for me.

Also I've been trying to follow this tutorial http://mongoosejs.com/docs/index.html to get something working on local host but no joy. But never mind that's for another thread :)

The Building a MEAN Application course covers the use of Mongoose.
