Routing Error

Rails
#1

Hi guys,

I’m experiencing an annoying problem that I’ve hit a brick wall on.
Basically I’m going through the Prag.Programmers Rails book and have got
to
building the depot application. I’ve set up mySQL ok and rails is
installed
and happy. However after running:

ruby script/generate scaffold Product Admin

All I am getting returned is a Rotuing error claiming that it couldn’t
recognise /Admin. I’ve done some Googling and found that this is a
problem
lots of people have had for numerous reasons - all of which I have tried
on
my install with no luck. I have ruby 1.8.4 on Ubuntu installed with
Rails
1.1.6. I am running MySQL 5 (which I can connect to via mysql admin
locally
on port 3306). I have installed all the mySQL libraries and run

gem install mysql (and picked 2.7).

My database.yml is setup to run mysql as root (with a password)
connecting
to localhost.I have also restarted WEBBrick a few times, and verified
that I
am running the server in the right place. One thing I did notice that
is
currently unexplained is an error during the scaffold generation (File
not
found /tmp/mysqld.sock) - which I don’t think is a problem as I am
trying to
connect over TCP.

Does anyone have any ideas?

Your mysql socket is likely somewhere other than the default
(/tmp/mysqld.sock) expected by rails. You can modify where rails looks
for the socket in your database.yml file with a line like:

sock: /var/lib/mysql/mysql.sock

This is what I use in FC4 installation. You need this line for each
environment in database.yml.

I’m not sure this has anything to do with a routing error, though. I
notice in your post of “/Admin” that it’s capitalized. I would expect
the URL to be all lowercase - “/admin” - and if so, then the routing
error when trying to access “/Admin” would make sense. Have you tried
accessing it with a lower-case url?

Yeah, I tried /admin too (along with a whole host of others in
desperation). As far as I am aware my mysqld.sock is in /var/run/mysql
somewhere (being Ubuntu Linux). Do I still need this even though I want
to
connect over TCP/IP? is it just a case of adding socket: /var/run…
into
the database.yml?

I’m not sure what you mean by “connect over TCP/IP” - do you mean your
MySQL server is on a different server from your rails application
server?

In any event, as I mentioned, I don’t think the mysql socket issue is
related to the routing issue (though I could be wrong with that). Can
you run “rake log:clear”, then attempt to access your application
address, and post up the resulting contents of your log file?

I have the same problem coincidently running Ubuntu (Edgy) but with
Postgresql.

Here’s what I did. Install ruby via apt, install ruby gems and rails
via instructions on rails site. Next I wrote a small test site by
myself that worked fine but did not use the database or rails scaffolds
(enter name, stuffs name in session and allows you to log out clearing
session). I decided to go back to the PragProg book and started on
chapter 6, installing the postgres gem.

Created and checked the database exists, that the user/password is
correct, that the rails page at http://localhost:3000 works. The
version info from that page is

Ruby version 1.8.4 (i486-linux)
RubyGems version 0.9.0
Rails version 1.1.6
Active Record version 1.14.4
Action Pack version 1.12.5
Action Web Service version 1.1.6
Action Mailer version 1.2.5
Active Support version 1.3.1
Application root /projects/learning/rails/depot
Environment development
Database adapter postgresql

development:
adapter: postgresql
database: depot_development
username: depot_dev
password: apassword
host: localhost

“./script/generate scaffold Product Admin” produced

  exists  app/controllers/
  exists  app/helpers/
  exists  app/views/admin

dependency model
exists app/models/
exists test/unit/
exists test/fixtures/
identical app/models/product.rb
identical test/unit/product_test.rb

Removing the directory and following all steps produces same output.
This was in log/development.log

Any ideas? The prag prog book suggests more files should be generated
but are not. app/view/admin is completely empty.

Cheers,
Chris

#7

After removing the native postgres gem then installing the postgres-pr
driver gem instead it works fine.

#8

I just tried this with mysql and had no problems… sigh. Any ideas
why it won’t work with postgresql? Is there any way to trace db
access when a scaffold is generated?

Cheers,
Chris
