Re: Creating permalink for blog tags that have the Post class as foreign key

I didn't think to check the shell! It is definitely issue 2.

I was able to output: 

>>> for tag in post.posttag_set.all(): tag.get_absolute_url()

... 

'/blog/footag/'

which is exactly what I expect. (I have one post with the tag "footag")

post = get_object_or_404(Post, tag='footag') returns the error:

FieldError: Cannot resolve keyword 'tag' into field. Choices are: html, id, posttag, pub_date, slug, title

 

So I tried: 

post = get_object_or_404(Post, posttag='footag') which returned:

ValueError: invalid literal for int() with base 10: 'zzz'

I think a lot of my issues are being caused by my ignorance of how I would refer to a Post objects tag since they are only related via foreign key.

btw, my templates print the tags perfectly with {% for tag in post.posttag_set.all %}

so seeing >>> for tag in post.posttag_set.all(): tag.get_absolute_url() print the tag url exactly came as a surprise to me.

Hi all, Django newbie here,

I have a simple blog app I am working on and am trying to figure out the best way to create a permalink for tags that I have added for blog posts. Basically, my models.py consists of two classes: Post and Tag, which has Post as a foreign key: http://dpaste.org/Ojhh5/

I am then trying to access the permalink to the tag using: {{ tag.get_absolute_url }} 

This doesn't seem to print anything however. I am basically just replicating the method I used to generate the permalink for the slug field in my Post class. I guess it isn't working since Tag is using post as a foreign key though or something? Being a beginner though, I really have no clue. 

Can explain what I am doing wrong as well as point me in the direction of the correct way to achieve the goal here?

Other relevant code:
