I am getting 2 querysets from db:
all_locations = Locations.objects.all()[:5]
rating = Rating.objects.all()[:5]
return render_to_response('index.html',{'all':all_locations,'rating':rating},context_instance=RequestContext(request))
But I am stuck here, not knowing how to loop over these 2 querysets in one loop. this is being wrong:
{% if all and rating %}
{% for every in all and rating %}
{{every.locationname}}, {{every.rating_score}}
{% endfor %}
{% endif %}
You can try zip(all_locations, rating). It will produce a list of tuples. Then you can iterate over them in pairs. Here is an example: (demo)
all_locations = ['ca','ny','fl']
ratings = ['best','great','good']
for (l,r) in zip(all_locations,ratings):
print l+':'+r
Outputs
ca:best
ny:great
fl:good
for (a,b) in list{% for (loc,bew) in zip(all_locations,bewertung) %}. ERROR: Could not parse the remainder: '(all_locations,bewertung)' from 'zip(all_locations,bewertung)'
I have also come across this problem. Now I've fixed it. what I do is using
new=tuple(zip(queryset1,queryset2))
return render(request, 'template.html', {"n": new}).
in view.py.
In template.html, I use three for sentences which are list below.
{% for i in n %}
{% for j in i|slice:"0:1" %}
......operate queryset1
{% endfor %}
{% for z in i|slice:"1:2" %}
.....operate queryset2
{% endfor %}
{% endfor %}
It seems this method will fulfill your needs.
this might work:
{% with rating|length as range %}
{% for _ in range %}
{{ rating[forloop.counter] }}
{{ location[forloop.counter] }}
{% endfor %}
{% endwith %}
i'm not sure if rating|length will to the job... you might need to add rating|length|times' withtimes` filter defined as:
@register.filter(name='times')
def times(number):
return range(number)
{% if all_locations and rating %} .. {% endif %}
Could not parse the remainder: '[all_locations,bewertung]' from '[all_locations,bewertung]'if i dofor (a,b) in [all_locations,bewertung].
