Plone：collective.transmogrifier.sections.constructor在导入

时间：2015-08-13 16:00:08

标签： plone data-migration plone-4.x transmogrifier

我几乎成功地将我的ZODB（一小部分文件夹，包括从其他文件夹中获取的资源）的摘录转移到另一个Plone实例; showstopper是：在导入期间，我的对象不会被写入。 这是我的导出脚本：

[transmogrifier]
pipeline =
    sitewalker
    xmlwalker
    uidextractor
    encapsulator
    manifestexporter
    fileexporter
    marshaller
    propertiesexporter
    commentsexporter
    datacorrector
    portletsexporter
    writer
    EXPORTING

[sitewalker]
blueprint = quintagroup.transmogrifier.sitewalker
path =
    folder1
    folder2

[xmlwalker]
blueprint = collective.transmogrifier.sections.xmlwalker

[uidextractor]
# my own section which parses the html text of the given fields,
# checks the href and src attributes for UIDs, and injects entries
# for the refered objects into the pipeline
blueprint = my.transmogrifier.uidextractor
inspect_fields =
    text
    description
    notes

[encapsulator]
blueprint = plone.app.transmogrifier.mimeencapsulator
mimetype = item/_mimetype
field = string:datafield

[manifestexporter]
blueprint = quintagroup.transmogrifier.manifestexporter

[fileexporter]
blueprint = quintagroup.transmogrifier.fileexporter

[marshaller]
blueprint = quintagroup.transmogrifier.marshaller

[propertiesexporter]
blueprint = quintagroup.transmogrifier.propertiesexporter

[commentsexporter]
blueprint = quintagroup.transmogrifier.commentsexporter

[datacorrector]
blueprint = quintagroup.transmogrifier.datacorrector
sources =
    marshall

[portletsexporter]
blueprint = quintagroup.transmogrifier.portletsexporter

[writer]
blueprint = quintagroup.transmogrifier.writer
context = directory
path = var/export/
prefix = structure

[EXPORTING]
blueprint = quintagroup.transmogrifier.logger
keys =
    _type
    _path

根据quintagroup.transmogrifier的默认导出和导入脚本，这是我的导入脚本：

[transmogrifier]
pipeline =
    reader
    pathfixer
    constructor
    schemaupdater
    datacorrector
    demarshaller
    uidupdater
    referencesimporter
    propertiesimporter
    commentsimporter
    portletsimporter
    printcounters
    IMPORTING

[reader]
blueprint = quintagroup.transmogrifier.reader
prefix = 
path = /path/to/var/export
context = directory
# unchanged entries I don't really understand:
.objects.xml = manifest
.marshall.xml = marshall
.properties.xml = propertymanager
.comments.xml = comments
.file-fields.xml = file-fields
.interfaces.xml = interfaces
.portlets.xml = portlets

[pathfixer]
blueprint = plone.app.transmogrifier.pathfixer
stripstring = Plone/
prependstring = 

[constructor]
blueprint = collective.transmogrifier.sections.constructor

[schemaupdater]
blueprint = plone.app.transmogrifier.atschemaupdater

[datacorrector]
blueprint = quintagroup.transmogrifier.datacorrector
type = import
sources =
    marshall

[fileimporter]
blueprint = quintagroup.transmogrifier.fileimporter

[demarshaller]
blueprint = quintagroup.transmogrifier.demarshaller

[uidupdater]
blueprint = plone.app.transmogrifier.uidupdater

[referencesimporter]
blueprint = quintagroup.transmogrifier.referencesimporter

[propertiesimporter]
blueprint = quintagroup.transmogrifier.propertiesimporter

[commentsimporter]
blueprint = quintagroup.transmogrifier.commentsimporter

[portletsimporter]
blueprint = quintagroup.transmogrifier.portletsimporter

[printcounters]
blueprint = collective.transmogrifier.sections.summary
count = true

[IMPORTING]
blueprint = quintagroup.transmogrifier.logger
keys = 
    _type
    _path

据我了解，reader出现在writer; marshaller出现demarshaller等。 但是，在导入时，对象实际上并未写入 数据库。用计数设备调整蓝图（在 我的包裹的add-info分支，我得到了以下内容 概述：

Items summary
~~~~~~~~~~~~~
[reader]:
  created:   714
[pathfixer]:
  got:         714
  forwarded:   714
  stripped:    390
[constructor]:
  got:            714
  missing-type:   714
  missing-info:   714
  forwarded:      714
[datacorrector]:
  got:         714
  forwarded:   714
[fileimporter]:
  got:          31
  forwarded:    31
[demarshaller]:
  got:          31
  forwarded:    31
[uidupdater]:
  got:          31
  forwarded:    31
[referencesimporter]:
  passed-through:    31
[printcounters]:
  passed-through:    31
[IMPORTING]:
  got:          31
  forwarded:    31

当constructor没有对item做任何事情时，我会计算原因;显然constructor部分没有写任何东西，因为它不知道要创建的对象的类型。但不应该这样 信息是在某处创建的？！

（还有一个问题：显然只有fileimporter收到了 datacorrector传递了714的31个对象。但首先我会 喜欢看任何进口的东西。）

我做错了什么？

哦，collective.transmogrifier.sections的在线文档会很好;他们甚至缺乏文档字符串......

修改：我的启用计数的分叉在这里（分支add-info）：

第二次修改：

当我在IMPORTING之前移动constructer部分时，计数器输出为：

Items summary
~~~~~~~~~~~~~
[reader]:
  created:   714
[pathfixer]:
  got:         714
  forwarded:   714
  stripped:    390
[IMPORTING]:
  got:         714
  forwarded:   714
[constructor]:
  got:            714
  missing-type:   714
  missing-info:   714
  forwarded:      714
[datacorrector]:
  got:         714
  forwarded:   714
[fileimporter]:
  got:          31
  forwarded:    31
[demarshaller]:
  got:          31
  forwarded:    31
[uidupdater]:
  got:          31
  forwarded:    31
[referencesimporter]:
  passed-through:    31
[printcounters]:
  passed-through:    31

因此，collector仍无法找到_type信息。

第三次编辑：

我添加了一个小工具，可以打印关于找到的项目的简短信息（默认情况下每个部分的第1项; _path和_type，其中包含值（如果存在）以及其他键的列表）。结果是：

[reader], item #1:
    _path=''
    other keys: _import_context (DirectoryImportContext)
[pathfixer], item #1:
    _path=''
    other keys: _import_context (DirectoryImportContext)
[pathfixer], item #2:
    _path=''
    other keys: _import_context (DirectoryImportContext)
2015-08-18 18:39:56 INFO IMPORTING _path=
[constructor], item #1:
    _path=''
    other keys: _import_context (DirectoryImportContext)
[reader], item #2:
    _path='some/archetypes/object/containing/a/video'
    other keys: _files (dict), _import_context (DirectoryImportContext)

确实在任何地方都没有_type个键，因此我需要一个提供它们的部分。

第四次编辑：

在manifestimporter之前重新插入constructor后，我得到了：

[reader], item #1:
    _path=''
    other keys: _import_context (DirectoryImportContext)
[pathfixer], item #1:
    _path=''
    other keys: _import_context (DirectoryImportContext)
[pathfixer], item #2:
    _path=''
    other keys: _import_context (DirectoryImportContext)
2015-08-19 10:15:43 INFO IMPORTING _path=
[constructor], item #1:
    _path=''
    other keys: _import_context (DirectoryImportContext)
[manifestimporter], item #1:
    _path=''
    other keys: _import_context (DirectoryImportContext)
[reader], item #2:
    _path='    [reader], item #1:
    _path=''
    other keys: _import_context (DirectoryImportContext)
[pathfixer], item #1:
    _path=''
    other keys: _import_context (DirectoryImportContext)
[pathfixer], item #2:
    _path=''
    other keys: _import_context (DirectoryImportContext)
2015-08-19 10:15:43 INFO IMPORTING _path=
[constructor], item #1:
    _path=''
    other keys: _import_context (DirectoryImportContext)
[manifestimporter], item #1:
    _path=''
    other keys: _import_context (DirectoryImportContext)
[reader], item #2:
    _path='some/archetypes/object/containing/a/video'
    other keys: _files (dict), _import_context (DirectoryImportContext)
...
2015-08-19 10:15:44 INFO IMPORTING
Pipeline processing time: 00:00:00
         715 items were generated in source sections
           2 went through full pipeline
         713 were discarded in some section

manifestimporter部分不会转发任何先前的项目，因此reader中的所有项目都会被丢弃。

第五编辑： 尝试recommended way使用“站点配置导出步骤”;我编辑了默认的导出脚本并尝试了导出，但我得到了以下回溯：

我的uidexporter部分是否包括在内并不重要。

第6编辑：

以下是我用于站点配置导出步骤的当前导出配置文件：

[transmogrifier]
pipeline =
    sitewalker
    manifestexporter
    fileexporter
    marshaller
    propertiesexporter
    commentsexporter
    datacorrector
    portletsexporter
    writer
    EXPORTING

[sitewalker]
blueprint = quintagroup.transmogrifier.sitewalker
exclude-contained = false
start-path =
    Plone/some/existing/structure

[manifestexporter]
blueprint = quintagroup.transmogrifier.manifestexporter

[fileexporter]
blueprint = quintagroup.transmogrifier.fileexporter

[marshaller]
blueprint = quintagroup.transmogrifier.marshaller

[propertiesexporter]
blueprint = quintagroup.transmogrifier.propertiesexporter

[commentsexporter]
blueprint = quintagroup.transmogrifier.commentsexporter

[datacorrector]
blueprint = quintagroup.transmogrifier.datacorrector
sources =
    marshall

[portletsexporter]
blueprint = quintagroup.transmogrifier.portletsexporter

[writer]
blueprint = quintagroup.transmogrifier.writer
context = tarball
path = var/export/
prefix =

[EXPORTING]
blueprint = quintagroup.transmogrifier.logger
keys =
    _type
    _path

第7次修改： 一个简短的信息reader需要哪种数据才能使constructor创建对象，以及导出管道的哪一部分（了解必要的选项）可以获得150点声望点; - ）

1 个答案:

答案 0 :(得分：0)

从比较到quintagroup.transmogrifier's import.cfg您缺少管道中的显示导入部分。他们的管道上写着：

pipeline =
    reader
    manifestimporter
    constructor
    datacorrector
    fileimporter
    demarshaller
    referencesimporter
    propertiesimporter
    commentsimporter
    portletsimporter
    IMPORTING
