What is the right way to create content programmatically

[Toni Haka-Risku]

Hi, coming from the Plone-world I would like to know how to create content progammatically in Kotti?

Here is my alternative solution and I'm not sure if it's the right way to do it:

 

view = CommentAddForm(context, request)

        comment = view.add(

            title=u'A title',

            description=u'A description',

            tags=[],

            example_text=message

        )

        from kotti.views.form import get_appstruct

        appstruct = get_appstruct(comment, CommentSchema())

        view.save_success(appstruct)

The CommentAddForm is just a view inherited from kotti.views.edit.AddFormView

"Working with content objects" in the docs has examples of adding
content using Python interface.
http://kotti.readthedocs.org/en/latest/developing/developer-manual.html#working-with-content-objects

Here's an example:

>>> from kotti.resources import get_root
>>> from kotti.resources import Document
>>> root = get_root()
>>> root['first'] = Document(title=u'First page')
>>> root['second'] = Document(title=u'Second page')
>>> root['third'] = Document(title=u'Third page')

Document can be Comment or whatever content type you have. You can
see that the constructor takes keyword arguments for use as
attributes. So if you have a dict with the attributes, maybe that's
'comment' in your example, then you can do:

>>> cm = Comment(**comment_info)

Assign your new object to a parent to have it persisted in the content tree:

>>> mydoc['mycomment'] = cm

OK I understand, but is my solution above "wrong" because the content object is created using get_appstruct()? That way I can create the object through form and  don't have to define ID manually. Thanks for your answer btw.

[Daniel Nouri]

You can use 'kotti.util.title_to_name' to set the ID the same way the
add form sets it.

>>> from kotti.util import title_to_name
>>> comment = Comment(...)
>>> name = title_to_name(comment.title, blacklist=context.keys())
>>> context[name] = comment

Thank you! That's all I need.
