NAME

Jifty::DBI::Column - Encapsulates a single column in a Jifty::DBI::Record table

CONTENTS

DESCRIPTION

This class encapsulates a single column in a Jifty::DBI::Record table description. It replaces the _accessible method in Jifty::DBI::Record.

It has the following accessors: name type default validator boolean refers_to readable writable length.

    new

    is_numeric

Returns true if the column is of some numeric type, otherwise returns false.

    is_string

Returns true if this column is a text field

    is_boolean

Returns true if this column is a boolean

    serialize_metadata

Returns a hash describing this column object with enough detail to fully describe it in the database. Intentionally skips record_class, all column attributes starting with _, and all column attributes which are undefined. The known attributes in the attributes hash are flattened and returned as well. The list of known attributes are:
container
label hints render_as
display_length
valid_values
available_values
autocompleted
documentation
no_placeholder Setting this to a true value causes load_by_cols in Jifty::DBI::record to not use a placeholder when loading the column. This can allow the database to come up with better query plans in some cases.

    serialize_metadata2

Returns a hash describing this column object with enough detail to fully describe it in the database. Intentionally skips record_class, all column attributes starting with _, and all column attributes which are undefined.

    validator

Gets/sets the validator coderef for the column.

    read

DEPRECATED. Use $column->readable instead.

    write

DEPRECATED. Use $column->writable instead.

    length

DEPRECATED. Use $column->max_length instead.

    until

DEPRECATED. Use $column->till instead.

    active

Returns the a true value if the column method exists for the current application version. The current application version is determined by checking the schema_version in Jifty::DBI::Record of the column’s record_class. This method returns a false value if the column is not yet been added or has been dropped.

This method returns a false value under these circumstances:
o Both the since trait and schema_version method are defined and schema_version is less than the version set on since.
o Both the till trait and schema_version method are defined and schema_version is greater than or equal to the version set on till.
Otherwise, this method returns true.
