Any feedback appreciated on the following. My most recent attempt to
identify the issue is a minimal Ruby/SQLite/ActiveRecord script, Pastied
here: http://pastie.textmate.org/492514 which brings up the following
when run from the command line (an empty database file already exists):
$ ./simple_db.rbx
[SNIP]/active_record/connection_adapters/sqlite3_adapter.rb:29:in
`table_structure': Could not find table 'users'
(1) Not really a 'camping' related pastie. See (3) for the same thing
done the 'camping way'.
(2) There seems to be nothing in the code above telling activerecord
to create your database schema unless you're doing seperate rake
db:migrate scripts outside of this script. My suspicion, therefore is
that the 'users' table simply does not exist in your database.
(3) This is a full working solution for camping 1.5:
#!/usr/bin/env ruby
$:.unshift File.dirname(__FILE__) + "/../../lib"
require 'camping'
Camping.goes :Dave
module Dave::Models
class User < Base
end
class CreateTables < V 1.0
def self.up
create_table :dave_users, :force => true do |t|
t.column :id, :integer, :null => false
t.column :name, :string, :limit => 255
t.column :password, :string, :limit => 255
end
def self.down
drop_table :dave_users
end
end
end
end
module Dave::Controllers
class Index < R '/'
def get
user = User.new()
user.id = "dave"
user.name = "Dave Everitt"
user.password = "davepass"
user.save
# user = User.find("dave")
# user.destroy()
render :fin
end
end
end
module Dave::Views
def fin
"Finished, no errors"
end
end
def Dave.create
Dave::Models.create_schema :assume => (Dave::Models::User.table_exists? ? 1.0
: 0.0)
end
***************************
Save this file as dave.rb. Note the Dave::Models.create_schema call
(as per point 2 above)
To get this to work I have the following gems installed:
$ gem list
*** LOCAL GEMS ***
activerecord (2.3.2)
activesupport (2.3.2)
builder (2.1.2)
camping (1.5.180)
markaby (0.5)
metaid (1.0)
sqlite3-ruby (1.2.4)
I run it with:
camping dave.rb
I then visited http://localhost:3301/ with my browser (which showed
"Finished, no errors").
To confirm that there is a table in the sqlite database with the
correct fields and with one record:
$ sqlite3 ~/.camping.db
SQLite version 3.6.10
Enter ".help" for instructions
Enter SQL statements terminated with a ";"
sqlite> .tables
dave_schema_infos dave_users sessions
sqlite> .header on
sqlite> select * from dave_users;
id|name|password
0|Dave Everitt|davepass
Hope some of the above points you in the 'right' direction.
Cheers,
Jonathan.
