Hi Rajesh,
thanks for your quick reply. I don't really understand your point but
i'll try to explain mine:
get_article_list is a queryset, it filters live articles and compares
them to todays date and returns only the ones that are in future. But
the thing is, before manytomany i had video field as foreignkey to
Video model and stuff worked - i used my templatetag and add
attributes (in for loop) .video, .body, .pub_date.
I really don't understand why this doesn't work - i thought i could
just loop through videos of an article and just display the first one
(it's like a thumbnail for an article).
I'm looking at your sample code:
@register.inclusion_tag('youtube-video.html')
def displayfirstvideo(article):
video = article.video.all()[0]
return {'video':video}
article.video.all() - isn't "video" here a manager? In my manager i'm
just filtering articles that have videos, like
Article.live.filter(video__isnull=False).. and when i add 2 videos to
an article, templatetag doesn't return one article with 2 videos, ut 2
same articles with 2 videos..
So my question here is.. what am i doing wrong? I just need a little
guide where to look.
Thanks for your help in advance,
Martin
