Setting Up Basic Browse Pages

Right now our app allows people to sign up, create a Thing, and then edit their Thing. However, the only way for users to browse all the Things your web app contains is by going to your homepage. Let's set up a basic browse page.

Note: We won't be setting up text search, like Google, due to it being way more complex and beyond the scope of this book. If you're interested in learning more about how to do this, check out Haystack (

As we only have a few fields on our model, let's build a page that just lists every Thing we have by name.

You'll probably want to add browse pages for each of those fields as you fill out your model with new fields for what you're specifically building. For example, my first Django project had fields for price range and location, and therefore "narrow by price" and "narrow by location" pages. We're going to build a simple example here, which is easily copied for other use-cases.

Set up your URL routing

Back to the familiar URLs-views-templates routine. Add in this new line:

# our new browse flow
    views.browse_by_name, name='browse'),
    views.browse_by_name, name='browse_by_name'),

# password reset URLs
    {'template_name': 'registration/password_reset_form.html'},

We're going to set up two new URLs at once: The first, which we'll list out every Thing's name with a link to its page. The second will allow us to specify a letter (/browse/name/a/ to search for names of Things that start with "a," for example.)

Set up the view

Next, off to your to add this new view:

def browse_by_name(request, initial=None):
    if initial:
        things = Thing.objects.filter(name__istartswith=initial)
        things = things.order_by('name')
        things = Thing.objects.all().order_by('name')

    return render(request, 'search/search.html', {
        'things': things,
        'initial': initial,

We're going to write a view that works for both URL routes. Neat, right?

The top line of the view where we have initial=None, this simply says that if there is no value passed in, then to assign it to None. So /browse/, which doesn't pass in initial letter, will have initial assigned to None. If you didn't have the None part, Python would whine that it expects something if it's empty.

Then we use an if-statement to determine what kind of database query we want to do, whether we are passing something in or not.

We're also using name__istartswith, another queryset filter like contains which we used before (More info: Note that we don't have to use a single letter to search — this code will work whether you searched for 'a' or 'hello', grabbing everything in your database that starts with your query.

Fairly simple, and making one view rather than two means less code, and ergo less maintenance.

Create the template

Last, our template. We're going to create one "search" template that'll work for both flows here and we can extend in the future for other browse cases.

Create a new directory for search in your templates, and then create your search.html file:

$ cd collection/templates/
collection/templates $ mkdir search
collection/templates $ cd search
collection/templates/search $ touch search.html

Note: Technically we're browsing, not searching, but I find calling the pages and process "search" easier.

Our search.html file:

{% extends 'base.html' %}
{% block title %}
    Browse - {{ block.super }}
{% endblock title %}

{% block content %}
        Browse Things{% if initial %} Starting with 
        '{{ initial|title }}'{% endif %}

    {% for letter in 'abcdefghijklmnopqrstuvwxyz' %}
    <a href="{% url 'browse_by_name' initial=letter %}" 
    {% if initial == letter %}class="active"{% endif %}>
        {{ letter|upper }}
    {% endfor %}

    {% for thing in things %}
            <a href="{% url 'thing_detail' slug=thing.slug %}">
                {{ }}
    {% empty %}
    <p>Sorry, no results!</p>
    {% endfor %}
{% endblock content %}

We're doing quite a bit of fun things here.

  • First, our headline. We're modifying the headline based on whether we're narrowing down by initial or not. Users will get a descriptive headline for both cases.
  • Note that in the headline, we have initial|title — one of the template tags we talked about earlier in Chapter 4. Why not |upper? I mentioned before this actually works with any letter or word, and chose |title so, if we searched for "hello" it would be displayed as "Hello" rather than "HELLO."
  • To display links for every letter in the alphabet, we're looping over the alphabet in the template. Again, less code (as compared to writing out all the links) means less maintenance.
  • We're adding an active class to the currently selected letter, which you can style using CSS.
  • We're looping over the lowercase alphabet but making it uppercase when displayed. This way our links look like /browse/name/a/ rather than /browse/name/A/. Both work, but the former looks better.
  • We loop over every result in our list and display a link to the Thing.
  • Last, {% empty %} is what the for loop will display if the list we pass in is empty.

Updating your nav and setting up redirects

There isn't a link to this page in the main nav, so we should update the nav:


    <a href="{% url 'contact' %}">Contact</a>
    <a href="{% url 'browse' %}">Browse</a>

The second nitpick is our URL — /browse/name/ works, as well as /browse/name/a/... but /browse/ will 404 since we haven't set up a route for it. It's not linked to, but someone might edit the URL in their browser. Let's redirect /browse/ page to /browse/name/ (adding permament makes it a 301 redirect, rather than 302).


# added RedirectView to this import statement
from django.views.generic import (TemplateView, 

# our new redirect view
url(r'^browse/$', RedirectView.as_view(pattern_name='browse', permanent=True)),
url(r'^browse/name/$', views.browse_by_name, name='browse'),
url(r'^browse/name/(?P<initial>[-\w]+)/$', views.browse_by_name, name='browse_by_name'),

Like TemplateView, which we used before to display a template without writing a view (for our About and Contact pages), RedirectView is another generic view that let's us avoid writing extra code and sets up a simple redirect.

We have another set of URLs that could benefit from this same treatment. Let's redirect /things/ to our browse page as well:

url(r'^things/$', RedirectView.as_view(pattern_name='browse', permanent=True)),
url(r'^things/(?P<slug>[-\w]+)/$', views.thing_detail, name='thing_detail'),
url(r'^things/(?P<slug>[-\w]+)/edit/$', views.edit_thing, name='edit_thing'),

Test the redirects out by going to http://localhost:8000/browse/ and http://localhost:8000/things/ and watch them automatically redirect to the correct pages.

There we go, a great start to building browsable pages for your website visitors. Commit your work!
