Rails scaffolding - cannot get access to MySQL

Hi,

A newbie in the RoR world, I’m already more or less stuck when
generating the scaffold for my first tutorial project …

When I try to generate scaffold code for my version of the ‘depot’
application from the ‘Agile rails …’ book, I receive the following
error:

#28000Access denied for user ‘bo’@‘localhost’ (using password: NO)

I’m pretty sure that the MySQL database priviliges are set correctly,
and also that my yml file is ok.

The entire response that I get;

Depot> ruby script/generate scaffold Product Admin
exists app/controllers/
exists app/helpers/
create app/views/admin
exists test/functional/
dependency model
exists app/models/
exists test/unit/
exists test/fixtures/
create app/models/product.rb
create test/unit/product_test.rb
create test/fixtures/products.yml
#28000Access denied for user ‘bo’@‘localhost’ (using password: NO)

My YML file for my development project:

development:
adapter: mysql
database: Depot_development
host: localhost
username: bo
password:

I hope very much that someone will have met the same obstacles, having
found a solution that I can adapt.

Any help very much appreciated,

Best regards,
Bo

you might be pretty sure but the response is telling you that it isn’t
working…

when you can access the mysql server @ localhost as user bo without a
password, then rails can do it too.

In cli…

mysql Depot_development -h localhost -u bo

it either connects or errors…in your case, it would error. That is the
connection that rails is trying to make from your info…

development:
adapter: mysql
database: Depot_development
host: localhost
username: bo
password:

Things I would look at…

Is your database Depot_development or depot_development?

Are you connecting via TCP/IP or socket? (your database.yml didn’t
specify)

I’m having a similar problem creating the scaffolding for the Depot
demo. When I run the generate scaffold script, it seems to stall after
it creates products.yml with no error. I am connecting to MySQL as root
with no password using socket. Has anybody else run into this?

depot> ruby script/generate scaffold Product Admin
exists app/controllers/
exists app/helpers/
exists app/views/admin
exists test/functional/
dependency model
exists app/models/
exists test/unit/
exists test/fixtures/
create app/models/product.rb
create test/unit/product_test.rb
create test/fixtures/products.yml

  • After it prints this, it just stalls. No error message is printed, nor
    does anything happen for 10+ minutes until I hit ctrl-C. When I hit
    ctrl-C this is what is printed:

I am able to connect to MySQL fine as root.

depot> mysql depot_development -h localhost -u root

You can turn off this feature to get a quicker startup with -A

Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 70 to server version: 5.0.18-standard

Type ‘help;’ or ‘\h’ for help. Type ‘\c’ to clear the buffer.

are you sure ^^^^^^^^^^^^^ that this is where your mysql.sock is?

ps aux|grep mysql.sock

on my Linux systems, the socket is /var/lib/mysql/mysql.sock

mysql.sock. I also tried commenting out the socket connection and using

host: localhost
port: 3306

instead. Same problem. The script just stalls in the same place as
before.


leave nothing to chance…

make sure that after password: there is only a line feed…no
spaces/tabs, etc.

try changing the socket from /tmp/mysql.sock to /private/tmp/mysql.sock

try putting in root’s password if root has a password

and finally, try using port 3306 from command line…

mysql localhost -P 3306 -u root

and see if you connect

I connect successfully using mysql depot_development -u root -P 3306
I tried changing the socket to /private/tmp/mysql.sock.

Same thing still. It just stalls after

I guess I forgot to mention, I’m running on Mac OS x 10.4.4 with MySQL
5.0.18.

Still stumped,

sorry - I’m out of ideas…

Craig

When I had a similar issue, I was able to resolve it by changing host
to 127.0.0.1 instead of localhost. Have you tried chaning your host
name? Also pay attention to the MySQL permissions table.

Hope it helps.

Nope, no luck. Thanks for the suggestions. I guess I’ll keep trying…

Well, technically the socket is in /private/tmp/mysql.sock, but there is
a link from root to /tmp. So, yes, this is the correct location of
mysql.sock. I also tried commenting out the socket connection and using

host: localhost
port: 3306

instead. Same problem. The script just stalls in the same place as
before.

I finally found a posting on this forum that fixed my problem.
