I've made my Schema and created a seeder file to upload data to my MongoDB server, but the data appears to remain unsent. I've restarted npm, run mongo, and mongod in seperate consoles (windows 10 machine). When I run 'use shopping' , then db.shopping.find(), nothing populates the console.
Here is a link to my gist https://gist.github.com/Satellite9/5e4ce3de5c19cee2f355d872b6d7d3c8

18,528 PointsHi Florian, the command line just moves down and displays nothing. I get the same response when I use "show collections." I changed my systems variable path to include the 'seed' directory. When I run command 'node product-seeder.js,' in the console, I receive a depracationwarning. Thank you for your reply.

Treehouse Guest TeacherHi Killeon,
How does the product-seeder know which database it connects to? The connection string to the database is in the app.js file as far as I can see. I think if you start the connection in your seeder and then run it, you should have the data populated.
Regards
Andrew

18,528 PointsHello Andrew,
Thank you for your reply. It resolved my issue.
Did the connection string need to go into seeder, as opposed to the app.js file, because the seeder is not technically part of the app? Because my understanding was the app.js was the place where I needed to require all packages that pertain to the application. Thank you again.

Treehouse Guest Teacherapp.js is just an entry point in to code that you want to run for the server. If you create other files that perform different tasks, mini-apps if you will, you need to establish their own connections to databases or what ever it needs to do. Your seeder had no idea of what the app.js is doing because it's not require()d.

18,528 PointsHi Seth, That is the syntax that I'm using, it does not appear to resolve the issue. Thank you for your reply.

I'd be interested to see what information you get back from
show databases
as well.

18,528 PointsHello Ken,
The 'show databases' command showed and empty admin and an empty local. The problem was the location of my connection string. It was in my app.js file and not my seeder. Although, my understanding, when I created the app.js, was that the everything had to run through that file first and always. I didn't realize the string was suppose to go into the seeder.
Thank you for your reply and time.
Ken Alger
Treehouse TeacherGreat that you resolved the issue.
For future trouble shooting, if doing a show databases or show dbs doesn't result in showing the desired database, that is an indication that the specific DB hasn't been created.
Remember that MongoDB doesn't create a database or collection until a document is created in the database.
Again, I'm pleased it all worked out.
Happy coding.
