I would like to put NEXT & PREV links to my detail page to get easily to Previous or Next item. I dont want to do it with DATE or ID, because it is totally impractical.
I dont want to use:
Model.get_next_by_FOO(**kwargs)
Model.get_previous_by_FOO(**kwargs)
How can I setup a column with for example numbers and sort by that. If I do integers it will sort like:
1 12 13 14 2 21 24 3 etc....doesnt work either.
What would be the simplest way for the user in CMS specify order and it will sort it and then I can use the NEXT and PREV.
models.py
class Art(models.Model):
pub_date = models.DateTimeField('date published')
title = models.CharField(max_length=200)
title_url = models.SlugField(max_length=200)
image = models.ImageField(blank=True, null=True, upload_to='uploaded_images')
graphics = models.ImageField(upload_to='images/art/',blank=True)
def image_thumbnail(self):
return '<a href="/media/%s" target="_blank"><img width="160px" src="/media/%s"/></a>' % (self.graphics, self.graphics)
image_thumbnail.allow_tags = True
image_thumbnail.short_description = 'graphics'
description = models.TextField(blank=True)
def __unicode__(self):
return self.title
views.py
def artdetail(request, art_title_url):
art = Art.objects.all().filter(title_url=art_title_url)
return render_to_response('nart-detail.html', {'art':art)
How can I on this example make next & prev buttons in the template to get next ot previous object and if I got to the end it will hide the next button etc....
My major concern is to make it proper way maybe by sort (number column) I am thinking wrong, I would like to know the best way how to achieve this that user is happy with easy customization.
