NAME

DBIx::Class::Manual::Reading - How to read and write DBIx::Class POD.

DESCRIPTION

This doc should help users to understand how the examples and documentation found in the DBIx::Class distribution can be interpreted.

Writers of DBIx::Class POD should also check here to make sure their additions are consistent with the rest of the documentation.

METHODS

Methods should be documented in the files which also contain the code for the method, or that file should be hidden from PAUSE completely, in which case the methods are documented in the file which loads it. Methods may also be documented and refered to in files representing the major objects or components on which they can be called.

For example, DBIx::Class::Relationship documents the methods actually coded in the helper relationship classes like DBIx::Class::Relationship::BelongsTo. The BelongsTo file itself is hidden from pause as it has no documentation. The accessors created by relationships should be mentioned in DBIx::Class::Row, the major object that they will be called on.

Method documentation

  • Each method starts with a "head2" statement of it's name.

  • The header is followed by a one-item list.

    The single item provides a list of all possible values for the arguments of the method in order, separated by , , preceeded by the text "Arguments: "

    Example (for the belongs_to relationship):

      =item Arguments: $accessor_name, $related_class, $fk_column|\%cond|\@cond?, \%attr?

    The following possible argument sigils can be shown:

    • $var - A scalar (string or numeric) variable.

    • \%var - A variable containing reference to a hash.

    • \@var - A variable containing a reference to an array.

    • \$var - A variable containing a reference to a scalar variable.

    • ? - Optional, should be placed after the argument type and name.

    • | - Alternate argument types.

    NOTES:

    If several arguments are optional, it is always possible to pass undef as one optional argument in order to skip it and provide a value for the following ones. This does not need to be indicated in the Arguments line, it is assumed.

    The ? for optional arguments always applies to the entire argument value, not a particular type or argument.

  • The argument list is followed by a single paragraph describing what the method does.

  • The description paragraph is followed by another list. Each item in the list explains one of the possible argument/type combinations.

  • The argument list is followed by some examples of how to use the method, using it's various types of arguments.

    The examples can also include ways to use the results if applicable. For instance if the documentation is for a relationship type, the examples can include how to call the resulting relation accessor, how to use the relation name in a search and so on.

    If some of the examples assume default values, these should be shown with and without the actual arguments, with hints about the equivalent calls.

    The example should be followed by one or more paragraphs explaining what it does.

    Examples and explaining paragraphs can be repeated as necessary.
