Creating Page Models and images programatically

We move a very old, very big, 90ties, PHPish peace of horror to wagtail.

I have written a script that somehow organizes the content from the old database. Next thing is the import into wagtail.

I have the images available (StringIO, Binary, doesn't matter) and page content (text or basic html) and title and the structure of page tree.

What I want to do:

- create a root page

- inject the original text and add the images (it does not have to look great as we have editors getting over it afterwards)

- add the child page to that root page with text and images

- recursively doing so until everything is smooth and shiny.

So what I need to understand is the best approach to create a Page() and an Image() in python - are there docs or anything to help? I would dive into the source if not :)

Okay, pages was rather easy

parent_page = Page.objects.get(id=site_root_id).specific
page = HomePage(
    search_description='',
    seo_title='foo',
    show_in_menus=False,
    slug='foobar',
    title='Foo Bar'
)

page.body.stream_data = [
    ('heading', 'This is a heading'),
    ('paragraph', RichText("<p>I'm a heading</p>"))
]

parent_page.add_child(instance=page)
revision = page.save_revision(
    user=self.import_user,
    submitted_for_moderation=False,
)
revision.publish()
page.save()

Hi Christian,

When you first create a page, you must use the add_child method of the page that you want to create it under.

For example, instead of calling page.save():

from wagtail.wagtailcore.models import Page

root_page = Page.get_root_nodes()[0]

root_page.add_child(instance=page)

This saves the page to the database, adding it underneath the "root" page.

For Images, you just need to create an instance of wagtailimages.models.Image (or your custom image model if you have one). You also need to convert the StringIO (Python 2)/BytesIO (Python 3) you have to an ImageFile object.

For example:

from django.core.files.images import ImageFile

from wagtail.wagtailimages.models import Image

image = Image(

title="Image title",

# image_file is your StringIO/BytesIO object

file=ImageFile(image_file, name="image-filename.jpg"),
)

image.save()

Django will automatically place your image file into the media folder.

Hope that helps,

Karl

Can you copy the entire file? don't work for me. :(

I want to create all pages of my app programmatically with default values, not inside of wagtail admin. i have the root page and rest of the pages will be child of root page, but only i can create it whit the admin panels, not programmatically.

Regards,

Diego
