Everyone:
I am learning catalyst from the book <Catalyst 5.8 the perl MVC
framework>. I have finished the two former chapters.
When I study the third chapter <Building a Real Application>, I can't run
the web application. What I have finished as follows:
1. $ catalyst.pl AddressBook
2. $ cpan Catalyst::Controller::FormBuilder Catalyst::Controller::BindLex
3. $ perl script/addressbook_create.pl view HTML TTSite
4. create a sqlite3 database; the database have two tables : people and
addresses. The database's directory is ~/addressbook/tmp/
5. $ perl script/addressbook_create.pl model AddressDB DBIC::Schema
AddressBook::Schema::AddressDB create=static dbi:SQLite:database
6. The book mentions <At this stage, you can do a quick sanity check and
see if the contents of the file lib/AddressBook/Schema/
AddressDB.pm have the following:>
---------------------------------------------
__PACKAGE__->config(
schema_class =>
'AddressBook::Schema::AddressDB',
connect_info =>
['dbi:SQLite:database',],
);
---------------------------------------------
I think, maybe I misunderstand the above sentences. The file
AddressDB.pm have no such code. Add or no, the error still.
7. others steps as books ......
I run the command : script/addressbook_server.pl -r -d; I get the follows:
------------------------------------------------------
Couldn't instantiate component "AddressBook::Model::AddressDB",

------------------------------------------------------
My questions:
1. I compare the second chapter code and the third chapter code, they are
as same:
--------------------------------------------------------
$ perl script/myapp_create.pl model TestDatabase DBIC::Schema MyApp::
Schema::TestDatabase create=dynamic dbi:SQLite:tmp/database
$ perl script/addressbook_create.pl model AddressDB DBIC::Schema
AddressBook::Schema::AddressDB create=static dbi:SQLite:database
---------------------------------------------------------
what's my mistake. How to solve this problem.
2. I got a computer bachelor degree in China. In fact, I am a newbie of
Perl and Catalyst. How to study Perl and Catalyst.
Respect your replay.
Thanks!
