Hi all
Im trying to place into a list of experiments the number of procedures for each
experiment.
>From within the views.py I can save the number of procedures in an experiment
>into either a list of tuples (e.id, count) or a dictionary {'e.id': count}.
>But when I come to access them in the templates I can't do something like {{
>e."e.id".1 }}
The template:
This works: {{ pcount.1.1 }} is the number of procedures in experiment 1.
This works: {{ pcount.2.1 }} is the number of procedures in experiment 2.
{% for e in experiment_list %}
{{ e.id }}
{{ e.name }}
{{ e."e.id".1 }} <----- what to use here though ???
{% endfor %}
In views.py:
def experiments(request):
experiment_list = Experiment.objects.all()
ecount = len(experiment_list) + 1
# TODO create a dictionary of the number of procedures in each experiment.
pcount = []
my_tuple = ()
for e in Experiment.objects.all():
my_count = e.experiment_procedure_set.all().count()
pcount.append( (e.id, my_count) )
return render_to_response('lab/experiments.html',
{'experiment_list': experiment_list,
'ecount': ecount, # ecount is the number of experiments.
'pcount': pcount, # pcount is the number of procedures in an
experiment.
})
There are references to 'dynamic lookup' of variables in the docs for template
authors.
But this seems very complex to use custom tags and filters. I know the docs can
be a little behind the development version so is there an easy way to do this?
