NAME

Padre::DB::Snippets - Padre::DB class for the snippets table

SYNOPSIS

TO BE COMPLETED

DESCRIPTION

TO BE COMPLETED

METHODS

select

# Get all objects in list context
my @list = Padre::DB::Snippets->select;

# Get a subset of objects in scalar context
my $array_ref = Padre::DB::Snippets->select(
    'where id > ? order by id',
    1000,
);

The select method executes a typical SQL SELECT query on the snippets table.

It takes an optional argument of a SQL phrase to be added after the FROM snippets section of the query, followed by variables to be bound to the placeholders in the SQL phrase. Any SQL that is compatible with SQLite can be used in the parameter.

Returns a list of Padre::DB::Snippets objects when called in list context, or a reference to an ARRAY of Padre::DB::Snippets objects when called in scalar context.

Throws an exception on error, typically directly from the DBI layer.

count

# How many objects are in the table
my $rows = Padre::DB::Snippets->count;

# How many objects 
my $small = Padre::DB::Snippets->count(
    'where id > ?',
    1000,
);

The count method executes a SELECT COUNT(*) query on the snippets table.

It takes an optional argument of a SQL phrase to be added after the FROM snippets section of the query, followed by variables to be bound to the placeholders in the SQL phrase. Any SQL that is compatible with SQLite can be used in the parameter.

Returns the number of objects that match the condition.

Throws an exception on error, typically directly from the DBI layer.

new

TO BE COMPLETED

The new constructor is used to create a new abstract object that is not (yet) written to the database.

Returns a new Padre::DB::Snippets object.

create

my $object = Padre::DB::Snippets->create(

    id => 'value',

    mimetype => 'value',

    category => 'value',

    name => 'value',

    snippet => 'value',

);

The create constructor is a one-step combination of new and insert that takes the column parameters, creates a new Padre::DB::Snippets object, inserts the appropriate row into the snippets table, and then returns the object.

If the primary key column id is not provided to the constructor (or it is false) the object returned will have id set to the new unique identifier.

Returns a new snippets object, or throws an exception on error, typically from the DBI layer.

insert

$object->insert;

The insert method commits a new object (created with the new method) into the database.

If a the primary key column id is not provided to the constructor (or it is false) the object returned will have id set to the new unique identifier.

Returns the object itself as a convenience, or throws an exception on error, typically from the DBI layer.

delete

# Delete a single instantiated object
$object->delete;

# Delete multiple rows from the snippets table
Padre::DB::Snippets->delete('where id > ?', 1000);

The delete method can be used in a class form and an instance form.

When used on an existing Padre::DB::Snippets instance, the delete method removes that specific instance from the snippets, leaving the object ntact for you to deal with post-delete actions as you wish.

When used as a class method, it takes a compulsory argument of a SQL phrase to be added after the DELETE FROM snippets section of the query, followed by variables to be bound to the placeholders in the SQL phrase. Any SQL that is compatible with SQLite can be used in the parameter.

Returns true on success or throws an exception on error, or if you attempt to call delete without a SQL condition phrase.

truncate

# Delete all records in the snippets table
Padre::DB::Snippets->truncate;

To prevent the common and extremely dangerous error case where deletion is called accidentally without providing a condition, the use of the delete method without a specific condition is forbidden.

Instead, the distinct method truncate is provided to delete all records in a table with specific intent.

Returns true, or throws an exception on error.

ACCESSORS

id

if ( $object->id ) {
    print "Object has been inserted\n";
} else {
    print "Object has not been inserted\n";
}

Returns true, or throws an exception on error.

REMAINING ACCESSORS TO BE COMPLETED

	mimetype VARCHAR(255),
	category VARCHAR(255),
	name VARCHAR(255), 
	snippet TEXT
)
