Folders not visible in RubyMine

Question

I am using RubyMine 8.0.3, I have 3 folders and 2 .rb files in controller/api/v1 , none out of 3 folders are visible but both .rb files are visible. I reopened the the IDE but nothing happened. I also tried the solutions mentioned in the following link: RubyMine Folder Tree doesn't refresh

Note:

1: When I open my project in sublime all folders are visible.

2: I have added .idea/ in my .gitignore file.

Answer 1

I couldn't find the source of the problem, but deleting the .idea/ folder worked for me.

Answer 2

I had a similar incident, but did not want to delete the .idea folder. After poking in the Preferences, I found that under Project Structure, the content root had gone missing. After clicking Add Content Root and double-clicking the root folder of the code, the subfolders are now visible.

Hope this helps others as it looks like you found the solution!
