Expression detail page

Now let's add an expression detail page that shows the content of a single expression of a work.

Add a new view to your views.py:

views.py
from django.views.generic import ListView, DetailView
from .models import Work, Expression

class WorkListView(ListView):
    model = Work
    
class ExpressionDetailView(DetailView):
    model = Expression
    slug_field = 'frbr_uri'
    slug_url_kwarg = 'frbr_uri'

Add the new view to your urls.py:

urls.py
from django.urls import path
from reader.views import *

urlpatterns = [
    path('', WorkListView.as_view(), name="home"),
    # the FRBR URI starts with a /
    path('expression<path:frbr_uri>', ExpressionDetailView.as_view(), name="expression"),
]

Now create a template called templates/reader/expression_detail.html. We'll start with just the title and the expression content.

expression_detail.html
<html>
<head>
  <title>{{ expression.title }}</title>
</head>
<body>
  <a href="{% url 'home' %}">Home</a>
  
  <h1>{{ expression.title }}</h1>
  
  <div>{{ expression.content|safe }}</div>
</body>

If there are other expressions on the same work (different language or date), how would the user find them?

If you visit an expression detail page, you'll see the title and some ugly content. In the next section we'll add formatting to the content.
