Database indexes
What are database indexes? If you’re building web apps powered by a relational database, you should know.
A database index is a data structure in the database which improves the speed of operations (typically row lookups) on a database table, or across tables. Think of it like…
If you ever get stuck with the following error “Access denied for user ‘root’@’localhost’ (using password: YES)” while trying to boot your Rails application, make sure the values in your DB config file are correct.
Developement: adapter: mysql database: test_db username: root password:
We spent a day debugging code before noticing that the difference between development db config and test db config was the usage of:
user: root
instead of
username: root
