SailsMVC Setup and mLab MongoDB Atlas Sessions

The first task we'll take care of in this course is to set up a SailsMVC Web App that comes with a couple of extras that are super useful. The most important aspect of this web app is that it comes with User Authentication so that we don't have to write that code ourselves. Once we set up our project, I'll also go over configuring Sessions with mLab and MongoDB Atlas. Getting sessions working properly will make our lives much easier in terms of restarting our application server.

Check to make sure you are white listing your IP address. In mongodb go to network access under the security panel and then add your IP address there.

Hey Brian! So I'm getting this error through using mLab way … "Error occurred in session middleware :: 'Error: secret option required for sessions\n …" It's like the 'secret' is not valid, or is required somewhere else in the project. But I'm not sure where. Big bummer, I bought this months ago and finally had time to get into it! Any thoughts on this?

Hi Bryan, I'm getting an error after I included the "url: '<my MongoDB URI>'," I also tried to use MonggoDB atlas but still having the same error. Before that, I can still run my project but after that even I try to remove the url and run it again, I can't run it anymore. I also check below. I believe I'm have the same problem. please help.

To anyone having trouble with setting up Atlas, I downloaded the project that Brian included and replaced all the files in my Sails Project Folder. After that, just go to your Cluster and copy YOUR url and then provide the password and it works as it should be!

If anyone is still seeing an 'error: Error occurred in session middleware :: 'Error: secret option required for sessions\n' +' message-- In Mongodb Atlas, use Node.js version 2.2.12 or later in the version dropdown to get the correct connection string along with mongo-connect version found in project download.

Yup same here.. getting the same exact error. mongo ^1.3.2 node js latest update. used the connection url recommended by mongodb atlas, but everything leads to that error.

Christopher J. Roura

Check to make sure you are allowing access on your network. To check in mongo db go to network access under security and while there add your current IP address. This bug tripped me up for a bit and will crash your app even if everything else is correct.

Hey did you find a solution for this? I am having the same issue. I try allowing network access from everywhere but that didn't work.

Christopher J. Roura

I figured this out from trial and error and a bit of my own research into mongodb. It took me about 2 hours to diagnose. It was a while of just researching the error messages

Ok, I managed to solve it as well.... I had to do a lot of googling as well lol. Not fully sure if all the steps I took were needed but if anyone is still experiencing the issues they can give these steps a try/ 1) Ensure that the database is created on the MongoDB Atlas site and replace the 'myFirstDatabase' (or 'test') in your collection string with the database name. 2) Ensure that mongodb-core is up to date... run 'npm install mongodb-core' 3) Ensure that sails-mango is up to date... run 'npm install sails-mongo --save' 4) Add ' ssl: true, stringify: false, ' In the session.js file P.S the 'stringify:false' was used to fix and another error that came up after I update the mongodb-core package Reference: https://stackoverflow.com/questions/42716874/mongodb-atlas-%EF%B8%8E-sailsjs-waterline-sails-mongo-adapter Hope these can help anyone who is experiencing the issue

Hey Brian, I think if you update nodejs and sailsjs you will get this error if you follow the same steps that you gave in this video. also heroku does not allow you to signup for mLab. They have updated there website! If you can please check if you can update your nodejs and sailsjs and see if this would work.

MaxApp

I have done a lot of research on how to fix this but still with no progress so far :( what I did is setup a new web app then go to Mongodb and create a project + a cluster + a username and allowed my IP address. then I went back to the project ran this npm install connect-mongo@1.1.0 --save --save-exact added the ^ symbol then ran this npm install connect-mongo lastly went to the session file and put this adapter: 'connect-mongo', url: 'mongodb://***', collection: 'sessions',

I have the url setup correctly because I took it and put it into the MyJournal project which I made before updating nodejs and sailsjs. And it worked correctly but after updating everything went down for me :(

For all those having trouble and getting unknown errors in mongodb, the most likely culprit is lack of network access through mongodb. To enable access in mongodb to your local network go to your cluster and then under the security tab click on network access. there add your current IP address to the list of IP addresses (will just have 0.0.0.0 to start).
