Hi everybody,
I am new in rubyonrails, and I am trying to learn it so I try to
implement tht examples in the agile web developement with rails. I have
stopped when I want to use scaffold. as it is mentionned in the book:
ruby script/generate scaffold Product Admin

but i get an error: it said no such file or directory /tmp/mysql.sock

I have checked my configuration of mysql and i found that mysql socket
is located on /var/run/mysqld/mysqld.scok

any help would be appreciated
thanks in advance
best regards,

Hi,

Put that:

/var/run/mysqld/mysqld.scok

into your database.yml in place of the /tmp/mysql.sock line.

Then just add the socket parameter in your database.yml file like this:

socket: /var/run/mysqld/mysqld.sock

Goodmorning,
I have followed this suggestion:

Then just add the socket parameter in your database.yml file like this:

socket: /var/run/mysqld/mysqld.sock
but it doesn’t work at all, it still says to me that:
dependency model
exists app/models/
exists test/unit/
exists test/fixtures/
identical app/models/product.rb
identical test/unit/product_test.rb
identical test/fixtures/products.yml
No such file or directory - /tmp/mysql.sock

I have tried to install mysql with gem, also It dosen’t work, he can’t
install mysql and the error is as following:

root@acer:~/source/depot# gem install mysql
