Scott,

Well, now there's two of us! :)

I'm having problems with the schema generator. As an FYI, I'm attempting 
to use it to create my initial schema (so I can start by doing the Right 
Thing).

My rails app is configured to use PostgreSQL, and I have the appropriate 
gem installed for that (and config/database.yml is pointing in the right 
place).

Other environmental stuff: Rails 1.0, Ruby 1.8.3, Gentoo Linux, PowerPC.

I perform the following commands:

rails <appname>
cd <appname>
vi config/database.yml # fix up to point at my PostgreSQL DB
script/generate migration initial_schema
vi db/migrate/001_initial_schema.rb
script/generate schema

If I don't have the mysql gem installed... nothing happens. No output, 
no files generated.

If I have the mysql gem installed (version 2.7), I get a nasty stack 
trace which I've pasted at the bottom of this message (along with the 
rest of the output).

There are a couple of things with this output: firstly, it seems that 
the generator isn't picking up the file at all (the migration tool seems 
to start at '001' rather than '0' now). Secondly, if I "fix" the 
MySqlAdapter call and give it four parameters, then it whines with a 
different error.

Suggestions? I'd really like this to work ;)

Thanks,

Paul

Short form: Paul, try downgrading Rails to 0.14.4 as a temporary  
workaround.

Details:
Paul's onto something -- I was also running PostgreSQL without the  
mysql gem installed.  Recently I did a reinstall of ruby on my Mac to  
fix some problems; I didn't reinstall mysql support.

I downgraded Rails + deps to 0.14.4, and again encountered the no  
output problem.  Once I installed the mysql gem, schema generator  
worked properly.  I then (re-)upgraded to Rails 1.0 and also received  
the same error as Paul: "Error: wrong number of arguments (3 for 4)".

Thus there are two issues: 1) an implicit dependency (== not  
represented in gem dependencies) on a mysql driver being present, and  
2) an interface incompatibility introduced in Rails 1.0.

John,

Thanks for the suggestion. I pulled out all of my rails-related gems, 
and installed 0.14.4 exclusively (I had a lot of cruft in there). It 
didn't really help though, I'm getting the "uninitialized constant 
Mysql" error message.

Might be that the version of activesupport that was installed by default 
was 1.2.4 rather than the 1.2.5 that you listed in your email. I've put 
back rails 1.0 and its dependencies for now.

The other question still unanswered is why the generator isn't finding 
my migration script. My file is in the default location, 
db/migrate/001_initial_schema.rb in my case, but when I run the schema 
generator the first line is "Found 0 migration classes" and then all the 
rest of the outputs are also zeros.

All very weird. I'm tempted to hack out the mysql schema generation for 
my own purposes, but that leaves the unprocessed migration.

For the record, here is my current list of gems:

actionmailer (1.1.5)
actionpack (1.11.2)
actionwebservice (1.0.0)
activerecord (1.13.2)
activesupport (1.2.5)
gruff (0.0.7)
mysql (2.7)
postgres (0.7.1)
rails (1.0.0)
rake (0.6.2, 0.5.4)
RedCloth (3.0.4)
schema_generator (0.9.0)
sources (0.0.1)
tzinfo (0.1.1, 0.0.4)

Thanks,

Paul

I just released version 1.0.1 of the schema generator; this *should*  
be compatible with Rails 1.0 *and* it should remove the implicit  
MySQL dependancy.  Sorry for the delay.
