Hello,
I am trying to find how to filter the entries of my blog by a set of
tags, using the Django models.
In particular there are two relations:
Blog (id, title, content)
Tag ( name, blog_id )
with Tag.blog_id foreign key of Blog.id
I want to select all blog entries that contain a certain set of tags.
For instance, I would express the query in SQL as:
SELECT * FROM blog_blog b WHERE EXISTS ( SELECT 1 FROM blog_tag t WHERE
t.blog_id = b.id AND lower(t.name) IN ('tag1', 'tag2', 'tag3') );
How to represent the same query with the Django QuerySets ?
Thanks,
Dean De Leo
