transmogrify.dexterity 3.0.0

A transmogrifier blueprint for updating dexterity objects

transmogrify.dexterity

Introduction

The transmogrify.dexterity package provides a transmogrifier pipeline section for updating field values of dexterity content objects. The blueprint name is transmogrify.dexterity.schemaupdater.

The schemaupdater section needs at least the path to the object to update. Paths to objects are always interpreted as being relative to the context. Any writable field who's id matches a key in the current item will be updated with the corresponding value.

Fields that do not get a value from the pipeline are initialized with their default value or get a missing_value marker. This functionality will be moved into a separate constructor pipeline...

The schmemaupdater section can also handle fields defined in behaviors.

Actually tested and supported fields

• TextLine or Text

• Bool

• List

• NamedFileField: needs a dict with data and filename or get the filename in a seperated value from the pipeline

• Date:"needs a datetime.date or datetime.datetime object, or a string in the following format "%Y-%m-%d"

• Datetime: needs a datetime.datetime object, or a string parseable by DateTime.DateTime e.g. "2015-12-31 17:59:59" or "2004/12/30 00:20:00 GMT+1" etc.

Default pipelines

This package also registers a number of pipelines for you to use. To add them to a GenericSetup profile, create a transmogrifier.txt with the name of the pipeline you wish to use.

transmogrify.dexterity.csvimport

This pipeline will convert a CSV file into dexterity content. To use it:

• Name your CSV entries.csv

• Create a file called transmogrifier.txt with the one line transmogrify.dexterity.csvimport

• Add both to a .tar.gz file

• Visit /Plone/portal_setup/manage_importSteps

• Select the tarball you just made

• "Import uploaded tarball"

...or add it as part of another GS profile.

The first row of the CSV is presumed to be column headings. Unless a special column, the column will be presumed to be a dexterity property to update on the type. Special column names are:-

• _type portal_type of content (optional, default is Document)

• _path Full path to content item, including content item.

• _folder Folder containing item, id will be derived from title

• _transitions Workflow transition (optional, default is "publish")

• Drop support to Python 2.7 @ericof

2.0.0 (2021-09-28)

• Import relations fields that were exported as UID. @wesleybl

• Update plone.dublincore behavior fields, even if the object doesn't have this behavior. @wesleybl

• Add suport to Python 3.7 and 3.8 @wesleybl

• Add suport to Plone 4.3, 5.0, 5.1 and 5.2 @wesleybl

1.6.4 (2018-12-14)

• Fix date deserialization to work with any kind of separator or when it is None. @gbastien

• DatetimeDeserializer: check for the case when value is an empty string. @erral

1.6.3 (2016-10-11)

• Refactor DexterityUpdateSection: Factor out determining default value, getting value from pipeline and updating fields into their own methods. @lgraf

1.6.2 (2016-05-24)

• Fix blueprint context for support with transmogrifier package (not collective.transmogrifier), which does not have dependencies to CMFPlone and thus doesn't provide a useful context. @thet

1.6.1 (2015-09-30)

• Do not import from deprecated zope.app.intid anymore, use zope.intid instead @jensens

• Fix deserializer if datetime is string "None". @elioschmutz

1.6.0 (2015-08-28)

• Implement new deserializer for datetime fields. @mbaechtold

1.5.2 (2015-07-13)

• Fix default container description to be unicode, not bytestring. See https://github.com/plone/plone.dexterity/pull/33 @jone

1.5.1 (2015-05-27)

• Make z3c.relationfield imports conditional. @jone

1.5 (2015-05-26)

• When retrieving the object via traversal from the path, check if it provides IDexterityContent. Traversal can also return attributes of objects, if no object can be found but the path element is named like an attribute. @thet

• Handle collective.jsonify structures, specifically _datafield_FIELDNAME and _content_type_FIELDNAME keys. @thet

• PEP8. @thet

• Add value converters for z3c.relationfield relation(-lists). @deiferni

1.2 (2013-08-29)

• Only update with a default value if there isn't a value already set on the field. (NB: before a default value would be set, regardless of the current field value). @lentinj

1.1 (2013-07-23)

• Don't try to write readonly fields @djowett

• Added in a generic CSV -> content pipeline @lentinj

1.0 (2011-11-17)

• Updated changelog to be zest releaser compatible @lgraf
