Displaying list of Blog Pages on the Index page

[Leonardo Mateo]

Hi,

I'm unable to get a list of blog pages to display on the index page. In my models.py I have a BlogPage and an IndexPage model, I have created a few blog pages, but when I access the Index page, they are not showing.

Here is the code:

from django.db import models

from modelcluster.fields import ParentalKey

from wagtail.wagtailcore.models import Page, Orderable

from wagtail.wagtailcore.fields import RichTextField

from wagtail.wagtailadmin.edit_handlers import FieldPanel, MultiFieldPanel, InlinePanel

from wagtail.wagtailimages.edit_handlers import ImageChooserPanel

from wagtail.wagtailsearch import index

class IndexPage(Page):

    intro = RichTextField(blank=True)

    def child_pages(self):

        return BlogPage.objects.live().child_of(self)

content_panels = Page.content_panels + [

FieldPanel('intro', classname='full'),

]

    subpage_types = ['blog.BlogPage']

class BlogPage(Page):

    date = models.DateField("Post date")

    intro = models.CharField(max_length=250)

    body = RichTextField(blank=True)

    search_fields = Page.search_fields + (

        index.SearchField('intro'),

        index.SearchField('body'),

    )

    content_panels = Page.content_panels + [

        FieldPanel('date'),

        FieldPanel('intro'),

        FieldPanel('body', classname="full")

    ]

And on my template, I have:

{% extends "base.html" %}

{% load wagtailcore_tags %}

{% block body_class %}template-index_page{% endblock %}

{% block content %}

<div class="intro">{{ self.intro|richtext }}</div>

{% for page in self.child_pages %}

  {{ page.title }}

  {{ page.intro }}

  

{% endfor %}

    

{% endblock %}

Could someone clarify what I'm doing wrong here.

Thanks,

Leo-

Hi Leo,
The code you've posted looks correct to me (apart from the content_panels definition of IndexPage being indented too much - but I'm guessing that was a transcription error rather than an actual error in the code). At this point I'd try some debugging on the command line (from your project root, run `./manage.py shell`):

from myapp.models import IndexPage, BlogPage

# you might neeed to change this to something like IndexPage.objects.get(slug='blog')
# if you have several index pages
index_page = IndexPage.objects.get()

index_page.child_pages()

If this returns no results, try variations like BlogPage.objects.live(), BlogPage.objects.all() until you find something that does work. If index_page.child_pages() does return the expected results, then that suggests the template might be at fault - try adding some extra text inside the {% for page in self.child_pages %} block to see if it's entering the loop or not.

Cheers,
- Matt

Matthew,

Thanks for the assistance, the lines BlogPage.objects.live(), BlogPage.objects.all() worked for me.

Are the BlogPage instances actually children of the IndexPage? Just using live() or all()will pick up BlogPages which are children of any page, including ones under different sites and even unpublished ones (in the case of all()).

Brett,

Thank you for the clarification, I will also look into this.

Regards,

Leo
