I have the following statement.
raise forms.ValidationError({'product_type':
[mark_safe('Product type <a href="/group/detail/%d/">N/A already exists</a> for this combination.' % na[0].product_group.id) ]})
This app has the following named url
url(r'^detail/(?P<pk>[0-9]+)/$', views.ProductGroupDetail.as_view(), name='group_detail'),
Is there a way to use {%url 'group_detail' %} format in the href rather than hard-coded urls?
Thanks.
Use reverse:
from django.core.urlresolvers import reverse
url = reverse('group_detail', args=[pk])
For a detail view, I recommend to implement get_absolute_url on the model. This method name is a Django convention. The Django Admin will test for it and link to it if present.
# models.py
class ProductGroupModel(Model):
def get_absolute_url(self):
return reverse('group_detail', args=[self.pk])
You can then easily use it with a model instance:
'Product type <a href="{url}">N/A already exists</a> for this combination.'.format(
url=obj.get_absolute_url())
You can use result of reverse function:
url = reverse('group_detail', kwargs={'pk': na[0].product_group.id})
[mark_safe('Product type <a href="%s">N/A already exists</a> for this combination.' % url ]})
