导出到包含字典的pickle文件

让我们将文件夹导出为包含字典的pickle文件。我们通过访问视图来完成此操作

>>> view = folder.unrestrictedTraverse('@@dicts-to-archive')
>>> view.context
<ATFolder at ...
>>> tar_gz_str = view()
>>> pickle_str = self.extract_to_str(tar_gz_str, 'dicts.pickle')
>>> dicts = pickle.loads(pickle_str)
>>> dicts
[{...}, ...]

让我们检查文件夹中的所有对象是否都已导出

>>> brains = catalog(path='/'.join(folder.getPhysicalPath()))
>>> len(dicts) == len(brains)
True

让我们检查返回的字典是否与文件夹中的对象匹配

>>> objs = [b.getObject() for b in brains]
>>> set(d['id'] for d in dicts) == set(o.getId() for o in objs)
True
>>> set(d['title'] for d in dicts) == set(o.Title() for o in objs)
True
>>> set(d.get('text') for d in dicts if d.has_key('text')) \
...     == set(o.getText() for o in objs if hasattr(o, 'getText'))
True

我们可以将文件夹导出到服务器上的目录，而不是下载.tar.gz文件

>>> view = folder.unrestrictedTraverse('@@dicts-to-directory')
>>> view.context
<ATFolder at ...
>>> view.request['directory'] = tmpdir
>>> view()
'Success.'
>>> pickle_path = join(tmpdir, 'dicts.pickle')
>>> pickle_file = open(pickle_path)
>>> dicts = pickle.load(pickle_file)
>>> dicts
[{...}, ...]

导出到其他格式

HTML到存档

>>> view = folder.unrestrictedTraverse('@@html-to-archive')
>>> tar_gz_str = view()
>>> len(tar_gz_str) > 0
True

HTML到目录

>>> old_tmpdir_len = len(os.listdir(tmpdir))
>>> view = folder.unrestrictedTraverse('@@html-to-directory')
>>> view.request['directory'] = tmpdir
>>> view()
'Success.'
>>> len(os.listdir(tmpdir)) > old_tmpdir_len
True

导入

记住，在之前的示例中我们创建了一个pickle文件

>>> import_dir = tmpdir
>>> 'dicts.pickle' in os.listdir(import_dir)
True

让我们清空我们的文件夹。稍后我们将使用导入视图重新创建对象

>>> old_folder_len = len(catalog(path='/'.join(folder.getPhysicalPath())))
>>> old_folder_len > 0
True
>>> folder.manage_delObjects(ids=folder.objectIds())
>>> len(folder.objectIds())
0

现在我们将导入pickle文件

>>> view = portal.unrestrictedTraverse('@@dicts-from-directory')
>>> view.request['directory'] = import_dir
>>> view()
'Success.'

让我们验证

>>> brains = catalog(path='/'.join(folder.getPhysicalPath()))
>>> len(brains) == len(dicts)
True
>>> len(brains) == old_folder_len
True
>>> objs = [b.getObject() for b in brains]
>>> set(d['id'] for d in dicts) == set(o.getId() for o in objs)
True
>>> set(d['title'] for d in dicts) == set(o.Title() for o in objs)
True
