(under development:currently transitioning from old format..check back :>))
After a while when doing ROR, you start to thinking…“hey..maybe when I finally get a job…they probably are not using SQLite..it might be good experience to do your development with some other database. Two of the most popular are PostgreSql and MySql.
I installed and set up both on my MAC Yosemite.
Here is the deal. I previously was playing with PHP and I had MAMP installed, which basiscally gives you a PHP/Apache/MySQL stack. I figured why not just use THAT MYSQL instance instead of installing a separate one.
Besides. I was not able to use MYSQL with my Rails applications ANYWAY until i sorted things out. The MAMP version the the MYSQL2 gem were not working together. Now..if you really want to get into the details…look at the code for the MYSQL2 gem. I am sure that you can just change some setting in there, and you would be fine. But I learned that after the fact.
Lets cut to the chase. If don’t want to uninstall your MAMP application(because…yeah…you are thinking that some day you will return to PHP!) then here is what you need to know.
If you get some error in your rails setup like “Can’t connect to local MySQL server through socket ‘/tmp/mysql.sock’ “ it’s because when you installed MAMP it has it’s own directories and location for the mysql.sock file.
I found that by just changing the config/database.yml to point to the correct mysql.sock file it works fine. Now..in my case, I had also installed a version of MYSQL with Homebrew. I did not bother to uninstall it. So I had the mysql.sock in another location. But..I think the mysql2 GEM looks for it in the default location anyway.
If you are having trouble with rails connecting, and you are using MAMP…try this.
Coming from my notes ..too tired right now..gotta paint.
