Processing PersonController#create (for 192.168.1.50 at 2007-07-20 10:19:55) [POST] ArgumentError in PersonController#create : wrong number of arguments (1 for 0)

New to rails, trying to do a pretty vanilla test-run app.

Here''s the beginning of a log dump from the subject error (with a
little formatting for readability):

Processing PersonController#create (for 192.168.1.50 at 2007-07-20
10:19:55) [POST]
  Session ID: 41bc1e6351c24a63c12f97354da28e08
  Parameters: {"commit"=>"Create",
                      "action"=>"create",
                      "controller"=>"person",
                     
"person"=>{"first_name"=>"Fred",
                                        
"last_name"=>"Flintstone",
                                        
"email"=>"fred-kOmEMmCHPphBDgjK7y7TUQ@public.gmane.org"}}

Neither this nor the rest of the log is telling me much :-)

How do you go about troubleshooting something like this?

TIA!

Nothing there says anything about any error. What does the rest of the
dump say?

Perhaps I''m confused by the tutorial I''m reading, but I
thought this
was a built-in function delivered by ''scaffold''.

/person/list works fine if I''ve manually entered person data in to the
DB, as does /person/destroy, but the default create action fails.

yeah the default scaffolding actions should work.  I was trying to
figure out if you added any custom methods to your create method..
Since it looks like somewhere along the line, a method is being called
with a parameter, where it shouldn''t have one.  What''s the
address of
the tutorial you''re following?

Note: I''m not following it exactly, more mapping it to my own little
trial app :-)

But the default `/person/new` page appears as it should, it''s just the
operation fails on submit.

A little more info, and I''m more puzzled than ever :-)

Going back to step one in the tutorial , I realized I''d totally skipped
the
''gem install mysql'' instruction. Unfortunately, that fails
miserably, but
that''s for a separate post.

However, the USD64K question is: how can my rudimentary app read
and update the DB without the driver, and then fail on trying to create
a new entry?

???

Well, that ''gem intall mysql'' doesn''t install a
driver, rather native
bindings for ruby. It''s totally an optional step, but it generally
speeds up db access.

That ArgumentError is strange. I tried to do a few noobish things
myself and couldn''t replicate it. Have you written some of your own
actions in the PersonController? If so, can we see the code for your
PersonController?

Also, I assume that you''re doing the scaffolding by including the line
''scaffold :person'' in the controller. Have you tried
scaffolding the
other way? Try running the command ''script/generate scaffold
yourController yourModel''. Note: That''ll blow away your
controller, so
back it up if there''s anything you might want later.

Thanks for clarifying that! So I can ignore that issue for now.

I had, but removing them didn''t change anything.

I tried this on a fresh new Rails instance and noticed that the controller
created for Person was ''people_controller'', /not/
''person_controller''.
Maybe some conflict there? In any case, it works fine now using the
second scaffold method, so let me wade back in and see what else I
can break :-)

At least I discovered Logger through this, but I''d be interested in any
pointers to general RoR troubleshooting tips/tricks/best practice.

Regardless, thanks for the help!
