(rather that being done on Session)

but this is wrong

and person_parser linked to schema_id

or parsable via a custom parser to scope the schema Helper factory class to generate entries (input entries).

Constructor Details

#initialize(e, schema:, person_parser: nil, default_parser: nil, attr_map: nil) ⇒ EntryFactory

Returns a new instance of EntryFactory.

Parameters:

  • e (Eco::API::Common::Session::Environment) —

    requires a session environment, as any child of Eco::API::Common::Session::BaseSession

  • schema (Ecoportal::API::V1::PersonSchema) —

    schema of person details that the parser will be based upon.

  • person_parser (nil, Eco::API::Common::People::PersonParser) (defaults to: nil) —

    set of attribute, type and format parsers/serializers.

  • attr_map (nil, Eco::Data::Mapper) (defaults to: nil) —

    attribute names mapper to translate external names into internal ones and vice versa.

Instance Method Details

#entries(data: (no_data = true; nil), file: (no_file = true; nil), format: (no_format = true; nil), **options) ⇒ Eco::API::Common::People::Entries

Helper that provides a collection of Entries, which in turn provides with further helpers to find and exclude entries. It accepts a file: and format: or data: but not both options together.

Parameters:

  • data (Array<Hash>) (defaults to: (no_data = true; nil)) —

    data to be parsed. It cannot be used alongside with file:

  • file (String) (defaults to: (no_file = true; nil)) —

    absolute or relative path to the input file. It cannot be used alongside with data:.

  • format (Symbol) (defaults to: (no_format = true; nil)) —

    it must be used when you use the option file: (i.e. :xml, :csv), as it specifies the format of the input file:.

  • options (Hash) —

    further options.

Options Hash (**options):

  • :encoding (String) —

    optional parameter to read file: by expecting certain encoding.

  • :check_headers (Boolean) —

    signals if the csv file headers should be expected.

Returns:

Raises:

  • Exception - if you try to provide data: and file: at the same time. - if you provide file: but omit format:. - if the format: you provide is not a Symbol. - if there is no parser/serializer defined for format:.

#export(data:, file: "export", format: :csv, encoding: "utf-8", internal_names: false) ⇒ Void

Helper that generates a file out of data:.

Parameters:

  • data (Eco::API::Organization::People) —

    data to be parsed.

  • file (String) (defaults to: "export") —

    absolute or relative path to the ouput file.

  • format (Symbol) (defaults to: :csv) —

    it specifies the format of the output file: (i.e. :xml, :csv). There must be a parser/serializer defined for it.

  • encoding (String) (defaults to: "utf-8") —

    optional parameter to geneate file: content by unsing certain encoding.

Returns:

  • (Void) —

    .

Raises:

  • Exception - if you try to provide data: in the wrong format. - if you file: is empty. - if the format: you provide is not a Symbol. - if there is no parser/serializer defined for format:.

#new(data, dependencies: {}) ⇒ Eco::API::Common::People::PersonEntry

Note:

this method is necessary to make the factory object work as a if it was a class PersonEntry you can call new on.

key method to generate objects of PersonEntry that share dependencies via this EntryFactory environment.

Parameters:

  • data (Hash, Person) —

    data to be parsed/serialized. Parsed: the external hashed entry. Serialized: a Person object.
