How to create a slug in Python Django?

To create a slug in Python Django, we can use the slugify function.

For instance, we write

from django.template.defaultfilters import slugify
slugify("b b b b")

to call slugify to return a string with the spaces between the b’s filled dashes.

To create a slug in Python Django, we can use the slugify function.

To redirect to named url pattern directly from urls.py in Python Django, we can call the RedirectView.as_view method.

For instance, we write

from django.views.generic import RedirectView

urlpatterns = patterns('',
    url(r'^some-page/$', RedirectView.as_view(pattern_name='my_named_pattern', permanent=False)),
    #...
)

to add the some-page URL into the urlpatterns.

In it, we call RedirectView.as_view to redirect to the view with the pattern name.

And we set permanent to set whether we want the redirect to be permanent.

To override default queryset in Python Django admin, we can override the get_queryset method in our model.

For instance, we write

class MyModelAdmin(admin.ModelAdmin):
    def get_queryset(self, request):
        qs = super(MyModelAdmin, self).get_queryset(request)
        if request.user.is_superuser:
            return qs
        return qs.filter(author=request.user)

to add the get_queryset into MyModelAdmin.

In it, we call call the super constructor with MyModelAdmin and self.

And we get the queryset wirth get_queryset from the super class.

And then we return the queryset we want according to the value of request.user.is_superuser.

To change the default Python Django date template format, we can use the date filter.

To iterate through dictionary in a dictionary in a Python Django template, we can loop through the items with a for loop.

For instance, we write

<table>
    <tr>
        <td>a</td>
        <td>b</td>
        <td>c</td>
    </tr>

    {% for key, values in data.items %}
    <tr>
        <td>{{key}}</td>
        {% for v in values[0] %}
        <td>{{v}}</td>
        {% endfor %}
    </tr>
    {% endfor %}
</table>

to loop through the data dict’s entries with a for loop.

We get the key value pairs with data.items.
