python - Filter queryset in django templates -


i have model followed:

class venture(models.model):     name = models.charfield(_('name'), max_length=255)     created = models.datetimefield(editable=false)     modified = models.datetimefield()   class questionset(models.model):     title = models.charfield(_(u'title'), max_length=100)   class question(models.model):     title = models.charfield(_(u'title'), max_length=255)     qset = models.foreignkey(questionset, related_name='questions')   class answer(models.model):     question = models.foreignkey(question, related_name='answers')     responder = models.foreignkey(user)     venture = models.foreignkey(venture, related_name='answers')     text = models.textfield(_(u'answer'), blank=true, null=true)     timestamp = models.datetimefield(auto_now_add=true)

there exists set of predefined questions users. each venture, have page each questionset lists questions in set , loop on questions followed:

<div> {{ venture.name }} </div> {% question in qset.questions.all %}   <div class="qset-question control-group">     {{ question.title }}     {# how access answer current venture? #}   </div> {% endfor %}

the question best way answer of question current venture. want output information answer here.

any appreciated.

i solved problem creating custom template tage. here code:

@register.assignment_tag def question_answer(venture, question):     answers = question.answers.filter(venture=venture)     return answers[0] if answers else none

then used this:

{% question_answer venture question answer %} {{ answer }}
