Category names with spaces in them break routing regex

[fosskers]

Django gives:

Reverse for 'posts_in_category' with arguments '('Comp Sci Guide',)'
and keyword arguments '{}' not found. 1 pattern(s) tried: ['cms/(?P<name>\\w+)/$']

Name uses the \w+ to search for a word. Multiple word names don't work. Do URLs even accept spaces in links? I think a slug field would be better than just using a string name for urls. So it'd direct it to 'cms/Comp-Sci-Guide' instead of 'cms/Comp Sci Guide'. Would probably need to change the regex to [-\w]+ instead of just \w, which only matches A-Z,a-z,0-9

We should have multi-word categories. For the name to be foo bar baz but for it to accept foo-bar-baz for the routing, what has to change?

Usually urls can have spaces, but they have to be escaped to some code no human bothers remembering.

Would just have to change the model to:

class Category(models.Model):
    # same as before just add
    slug = models.SlugField()

And change the view to

class PostListView(generic.ListView):
    def get_queryset(self):
        return Post.objects.filter(category__slug = self.kwargs['slug'])

And edit the urls.py abit to

    url(r'^(?P<slug>[-\w]+)/$', views.PostListView.as_view(), name='posts_in_category'),

ez pz lemon squeezy

We can even add to admin.py

class CategoryAdmin(admin.ModelAdmin):
    prepopulated_fields = {"slug": ("name",)}

so that slug is automatically a sluged version of the name. i.e. spaces are converted to -
