首页布局
编辑 /slowread/home/models.py ，内容如下：
class HomePage(Page):
body = RichTextField(blank=True)
def get_context(self, request):
# Update context to include only published posts, ordered by reverse-chron
context = super().get_context(request)
page = Page.objects.get(title="文章列表")
blogpages = page.get_children().live().order_by('-first_published_at')[:3]
context['blogpages'] = blogpages
return context
content_panels = Page.content_panels + [
FieldPanel('body', classname="full"),
]
编辑 /slowread/home/templates/home/home_page.html ，内容如下：
{% extends "base.html" %}
{% load wagtailcore_tags wagtailimages_tags %}
{% block body_class %}template-homepage{% endblock %}
{% block content %}
<h1 class="mt-2">{{ self.title }}</h1>
{{ page.body|richtext }}
<hr>
<div class="card-deck mb-2">
{% for post in blogpages %}
{% with post=post.specific %}
<div class="card" style="width: 18em;">
{% with post.main_image as main_image %}
{% if main_image %}
{% image main_image fill-320x240 as header_image %}
<a href="{% pageurl post %}">
<img src="{{ header_image.url }}" class="card-img-top" />
</a>
{% endif %}
{% endwith %}
<div class="card-body">
<h5 class="card-title"><a href="{% pageurl post %}">{{ post.title }}</a></h5>
<p class="card-text">
{% if post.intro %}
{{ post.intro|richtext }}
{% else %}
{{ post.body|richtext|truncatewords_html:80 }}
{% endif %}
</p>
</div>
<div class="card-footer">
<small class="text-muted"><a href="{% pageurl post %}" class="btn btn-primary">阅读全文</a></small>
</div>
</div>
{% endwith %}

</div>
<hr>
<a class="nav-link text-center" href="/blog">更多文章</a>
<hr>
{% endblock %}
文章列表页分页
编辑 /slowread/blog/models.py ，修改 BlogIndexPage 内容如下：
class BlogIndexPage(Page):
intro = RichTextField(blank=True)
def get_context(self, request):
# Update context to include only published posts, ordered by reverse-chron
context = super().get_context(request)
blogpages = self.get_children().live().order_by('-first_published_at')
paginator = Paginator(blogpages, 3) # Show 3 resources per page
page = request.GET.get('page')
try:
blogpages = paginator.page(page)
except PageNotAnInteger:
# If page is not an integer, deliver first page.
blogpages = paginator.page(1)
except EmptyPage:
# If page is out of range (e.g. 9999), deliver last page of results.
blogpages = paginator.page(paginator.num_pages)
# make the variable 'resources' available on the template
context['blogpages'] = blogpages
return context
content_panels = Page.content_panels + [
FieldPanel('intro', classname="full")
]
采用Boostrap 4 的分页 Pagination 导航样式，编辑 /slowread/blog/templates/blog/blog_index_page.html ，内容如下：
{% extends "base.html" %}
{% load wagtailcore_tags wagtailimages_tags %}
{% block body_class %}template-blogindexpage{% endblock %}
{% block content %}

<!-- <div class="intro">{{ page.intro|richtext }}</div> -->
{% for post in blogpages %}
{% with post=post.specific %}
<div class="card mb-2">
<h4 class="card-header"><a href="{% pageurl post %}">{{ post.title }}</a></h4>
<div class="card-body">
<div class="row">
<div class="col-auto mr-auto">
{% if post.intro %}
{{ post.intro|richtext }}
{% else %}
{{ post.body|richtext|truncatewords_html:80 }}
{% endif %}
<a href="{% pageurl post %}" class="btn btn-primary mt-2 mb-2">阅读全文</a>
</div>
<div class="col-auto">
{% with post.main_image as main_image %}
{% if main_image %}
<a href="{% pageurl post %}">
{% image main_image fill-160x100 %}
</a>
{% endif %}
{% endwith %}
</div>
</div>
</div>
</div>
{% endwith %}
{% endfor %}
<nav aria-label="Page navigation">
<ul class="pagination justify-content-center">
{% if blogpages.has_previous %}
<li class="page-item">
<a class="page-link" href="?page={{ blogpages.previous_page_number }}">«</a>
</li>
{% endif %}
{% for page_num in blogpages.paginator.page_range %}
<li {% if page_num == blogpages.number %} class="active page-item"{% endif %}>
<a class="page-link" href="?page={{ page_num }}">{{ page_num }}</a>
</li>
{% endfor %}
{% if blogpages.has_next %}
<li class="page-item">
<a class="page-link" href="?page={{ blogpages.next_page_number }}">»</a>
