I used to use Sqlite3 as my database now I changed to MySQL installed mysql2 v=0.2.10 and now my application doesn’t run. I get the exact same error as the one pasted here.
What can I do?
Found the problem:
in my config/database.yml file I had the following entry for both production and development configuration.
pool: 5
I removed that and it seems to work just fine. Well I guess it helps someone.
Kudos to myself. 
hi… how to create a form in rails without using a scaffold command?
Has this question got anything to do with the subject line (Rails 3.0.7 and MySQL)? Please ask this again as a new posting with a meaningful subject. That way someone with an interest in the question is more likely to read it. The answer to your question, however, is to use form_for in the view file. Study the files generated by a scaffold command and just replicate this yourself. If you want further information please start a new thread.
