Import infrastructure for icemac.addressbook

Project description

This package provides import infrastructure for icemac.addressbook.

Copyright (c) 2008-2018 Michael Howitz

Importing data requires the following steps:

  • A user having the Administrator role uploads an import file to the address book. It gets stored there inside the importer.
  • When the user decides to import the the uploaded file, he is presented with a list of readers which claim to be able to read the import file.
  • After choosing the import file reader the user has to map which field data in the import file should be stored in which field in the address book.
  • The imported data gets shown and the user can decide to keep or to discard the imported data.

Running Tests

To run the tests yourself call:

$ virtualenv-2.7 .
$ bin/pip install zc.buildout
$ bin/buildout
$ bin/py.test

Write your own import file reader

The key to extend the import mechanism is to provide a reader for the needed import file type.

This package already provides an import file reader for CSV files.

icemac.ab.importxls provides a reader for XLS files, so it could be a starting point, too.

1. Write a reader class

The reader class must implement the interface icemac.ab.importer.interfaces.IImportFileReader. There is a base implementation in icemac.ab.importer.reader.base.BaseReader which the new reader class can extend, so there are only four things left to implement (see the interface for a more specific description):

  • title attribute – shown to the user in the dialog when choosing the reader
  • getFieldNames method – lists the names of the fields in the import file
  • getFieldSamples method – returns samples of a specific field to ease the mapping task for the user
  • __iter__ method – iterates the import file to get the data for the import.

The base class file stores the file for reading on the file attribute.

2. Test reader class

icemac.ab.importer.reader.testing.ReaderTest provides a (base) test class which checks whether the reader behaves as expected. It requires some example files for the reader. The derived reader tests must fulfill the following conventions:

  1. The directory structure must look like this: (directories in italic)

    • tests
      • data
        • short.file
        • long.file
  2. The file can be empty.

  3. The file contains the test class which extends icemac.ab.importer.reader.testing.BaseReaderTest. Three attributes have to be set on this class:

    • reader_class - must point to the reader’s class object
    • import_file - name of the longer import file (see below), without path
    • import_file_short name of the shorter import file (see below), without path
  4. There must be two files in the data directory:

    • a file for the import_file_short attribute on the test class, containing the following data:

      last name firstname birth_date
      Koch   1976-01-24
    • a file for the import_file attribute on the test class, containing the following data:

      last name firstname birth_date
      Koch Andreas 1976-01-24
      Hula Hanna 2000-01-01
      Jänsen Jens  
      Fruma   2001-12-31

3. Register the reader class

To register the reader class with icemac.addressbook write a configure.zcml file in the reader package:

<configure xmlns="">
  <include package="icemac.ab.importer" />
     factory="<path>" />

The icemac.ab.importer package is necessary to integrate the importer UI into the address book. The name attribute contains a unique name to identify the importer internally. The factory attribute contains the python path to the reader class.

4. Create a python package

The reader class must be inside a python package. The package must depend on icemac.ab.importer (install_requires parameter in

5. Integrate the reader in icemac.addressbook

During installing icemac.addressbook, it is possible to enter the name of external dependencies. This is the place to integrate your reader into icemac.addressbook.
