Vend::Table::Editor(3pm) User Contributed Perl Documentation Vend::Table::Editor(3pm)NAME
Vend::Table::Editor -- Interchange do-all HTML table editor
SYNOPSIS
[table-editor OPTIONS]
[table-editor OPTIONS] TEMPLATE [/table-editor]
DESCRIPTION
The [table-editor] tag produces an HTML form that edits a database table or collects values for a "wizard". It is extremely configurable as
to display and characteristics of the widgets used to collect the input.
The widget types are based on the Interchange "[display ...]" UserTag, which in turn is heavily based on the ITL core "[accessories ...]"
tag.
The "simplest" form of "[table-editor]" is:
[table-editor table=foo]
A page which contains only that tag will edit the table "foo", where "foo" is the name of an Interchange table to edit. If no "foo" table
is "defined", then nothing will be displayed.
If the "mv_metadata" entry "foo" is present, it is used as the definition for table display, including the fields to edit and labels for
sections of the form. If "ui_data_fields" is defined, this cancels fetch of the view and any breaks and labels must be defined with
"ui_break_before" and "ui_break_before_label". More on the view concept later.
A simple "wizard" can be made with:
[table-editor
wizard=1
ui_wizard_fields="foo bar"
mv_nextpage=wizard2
mv_prevpage=wizard_intro
]
The purpose of a "wizard" is to collect values from the user and place them in the $Values array. A next page value (option mv_nextpage)
must be defined to give a destination; if mv_prevpage is defined then a "Back" button is presented to allow paging backward in the wizard.

Alzabo::Table - Table objects
SYNOPSIS
use Alzabo::Table;
my $t = $schema->table('foo');
foreach $pk ($t->primary_keys)
{
print $pk->name;
}
DESCRIPTION
Objects in this class represent tables. They contain foreign key, index, and column objects.
METHODS
schema
Returns the "Alzabo::Schema" object to which this table belongs.
name
Returns the name of the table.
column ($name)
Returns the "Alzabo::Column" object that matches the name given.
An "Alzabo::Exception::Params" exception is throws if the table does not contain the column.
columns (@optional_list_of_column_names)
If no arguments are given, returns a list of all "Alzabo::Column" objects in the schema, or in a scalar context the number of such tables.
If one or more arguments are given, returns a list of table objects with those names, in the same order given.
An "Alzabo::Exception::Params" exception is throws if the table does not contain one or more of the specified columns.
has_column ($name)
Returns a voolean value indicating whether the column exists in the table.
primary_key
In array context, return an ordered list of column objects that make up the primary key for the table. In scalar context, it returns the
first element of that list.
primary_key_size
The number of columns in the table's primary key.
column_is_primary_key ("Alzabo::Column" object)
Returns a boolean value indicating whether the column given is part of the table's primary key.
This method is really only needed if you're not sure that the column belongs to the table. Otherwise just call the "Alzabo::Col-
umn->is_primary_key" method on the column object.
attributes
A table's attributes are strings describing the table (for example, valid attributes in MySQL are thing like "TYPE = INNODB".
Returns a list of strings.
has_attribute
This method can be used to test whether or not a table has a particular attribute. By default, the check is case-insensitive.
* attribute => $attribute
* case_sensitive => 0 or 1 (defaults to 0)
Returns a boolean value indicating whether the table has this particular attribute.
foreign_keys
Thie method takes two parameters:
* column => "Alzabo::Column" object
* table => "Alzabo::Table" object
It returns a list of "Alzabo::ForeignKey" objects from the given column to the given table, if they exist. In scalar context, it returns
the first item in the list. There is no guarantee as to what the first item will be.
An "Alzabo::Exception::Params" exception is throws if the table does not contain the specified column.
foreign_keys_by_table ("Alzabo::Table" object)
Returns a list of all the "Alzabo::ForeignKey" objects to the given table. In scalar context, it returns the first item in the list.
There is no guarantee as to what the first item will be.
foreign_keys_by_column ("Alzabo::Column" object)
Returns a list of all the "Alzabo::ForeignKey" objects that the given column is a part of, if any. In scalar context, it returns the first
item in the list. There is no guarantee as to what the first item will be.
An "Alzabo::Exception::Params" exception is throws if the table does not contain the specified column.
all_foreign_keys
Returns a list of all the "Alzabo::ForeignKey" objects for this table. In scalar context, it returns the first item in the list. There is
no guarantee as to what the first item will be.
index ($index_id)
This method expects an index id as returned by the "Alzabo::Index->id" method as its parameter.
The "Alzabo::Index" object matching this id, if it exists in the table.
An "Alzabo::Exception::Params" exception is throws if the table does not contain the specified index.
has_index ($index_id)
This method expects an index id as returned by the "Alzabo::Index->id" method as its parameter.
Returns a boolean indicating whether the table has an index with the same id.
indexes
Returns all the "Alzabo::Index" objects for the table.
comment
Returns the comment associated with the table object, if any.
