Access other object fields in StreamField / RichText field/block in wagtail - wagtail

Question

I would like to do the following:
Create some django model (or wagtail page) that contains data.
Create another Page type that includes a StreamField or RichtextField.
3.
When the author or editor enters text in this field, he/she can have the information of this appear somewhere in the rendered output of the text. Preferably using common template techniques.
So, lets say, we have a model like this:
class Person(models.Model):
name = models.CharField(max_length=30)
Then I have a normal page that uses a StreamField:
class NormalPage(Page):
body = StreamField(block_types=[
('paragraph', blocks.RichTextBlock()),
])
content_panels = Page.content_panels + [
StreamFieldPanel('body')
]
I would like for the editor to choose which Person he/she would like from the database and the be able to do something like this in the RichTextBlock:
{{ person.name }}
Is this possible?

Answer 1

In order to be able to choose a plain Django model, register it as a snippet as shown here, and then use SnippetChooserPanel to choose the person:
from wagtail.snippets.models import register_snippet
#register_snippet
class Person(models.Model):
name = models.CharField(max_length=30)
And then if you want to associate a particular person with a particular page:
from wagtail.snippets.edit_handlers import SnippetChooserPanel
class NormalPage(Page):
body = StreamField(block_types=[
('paragraph', blocks.RichTextBlock()),
])
person = models.ForeignKeyField(Person)
content_panels = Page.content_panels + [
StreamFieldPanel('body'),
SnippetChooserPanel('person'),
]
