i have written these models in models.py:
class User(models.Model):
first_name = models.CharField(max_length=80)
class Skill(models.Model):
user = models.ForeignKey(User)
title = models.CharField(max_length=80)
level = models.IntegerField(default=3)
class Work(models.Model):
user = models.Foriegnkey(User)
work_name = models.CharField(max_length=80)
salary = models.IntegerField()
now i want to get those Works from database which their users have a certain skill, and render a html with them. i write this code in views.py:
def show_works(request, skill):
works = Work.objects.select_related().filter(user__skill__title=skill)开发者_C百科
return render_to_response("works.html", {'works':works})
but there is another thing i want to show in that html: i want to show first_name of the user of that work and his skills. i used select_related(), but i can only show first_name but i can't reach user's skills.
i want to write an optimal query to get the works and the other extra informations, like user and the skills of it user! like the code blow: ( i don't want to hit database for every work to get its user's skills )
template works.html:
{% for work in works %}
{{work.work_name}}
user is : {{work.user.first_name}}
which has these skills:
{% for skill in work.user.skill %}
{{skill.title}}
{% endfor %}
{% endfor %}
You'll probably never look at this again, but I'll try to answer it anyway.
I would think that this should work:
{% for skill in work.user.skill_set.all %}
{{skill.title}}
{% endfor %}
