Using load() with Mongo

hello :)

Just a quick question with the load command in MongoDB,

I had a lot of trouble when following the video trying to connection to seed.js, probably because I'm working in a different setup to a Mac.

Then I remembered about the data/db directory and placed my project in there. 

load('/data/db/Mongo-Projects\treehouse-mongo-basics/seed.js')

It worked, and I was able to run commands on it.

But it never worked unless I placed the seed file in that directory even though it looked liked Huston was able to run commands from other locations.

Why is this? I know we're looking for relative paths from the current working directory, but that's different from just the data/db directory.

And another question in case anyone finds this thread.... when loading the seed.js file I find Huston takes up some data when using the show db's command, but when I do it comes up as 0.0000gb for both databases.

This suggests to me that no data has been loaded... yet I'm still able to load queries and methods from it. Odd.

I know this conversation is rather old, but I got stuck with this, so in case someone else is using Windows and is stuck...

In my case, it wouldn't load the file when I used the load('full_path_to_file') as suggested above, however, after I exited all the folders and then used cd('path_to_file_folder') and then load('file'), it actually loaded it.

I got it to work by just putting in the absolute file path. ex: load('C:/projectfolder/seed.js')

I think in the video he changes the directory he is in, but he does it very fast. (FYI - I am working on windows through ConEmu)

I didn't get anything to work, i copy pasted the absolute path from windows explorer. BUT! When i changed all the "\" to "/" it worked. I did like ieva graudule, cd('e:/the/directory') then load('seed.js')

I hope this helps someone
