SQLite3::CantOpenException

Hi,

When I try to run a controller that connects to my project’s sqlite
database, I get the following exception:

SQLite3::CantOpenException in PostController#index
could not open database

config/database.yml correctly points to my database, like so:

development:
adapter: sqlite3
database: db/dev.db

I’ve had Rails projects working with sqlite3 before (recently), but
starting any new projects has always lead to this error. I can’t figure
out what’s making the difference between the working and broken
projects…

Here is the full trace:
