How to print the value of a key from the key itself
dict={}
dict.update({'aa':1})
dict.update({'ab':1})
dict.update({'ac':1})
return render_to_response(t.html, context_instance=RequestContext(request, {'dict':dict}))
So in this case i want to print the key alert('{{dict.aa}}');
ie,without using any loop can we just print the key with the reference of aa in the the above example may some thing like if {{dict['aa']}} should give the value of aa
Never call a dictionary dict
, that would overwrite the builtin dict
type name in the current scope.
You can access keys and values in the template like so:
{% for item in d.items %}
key = {{ item.0 }}
value = {{ item.1 }}
{% endfor %}
or use d.keys
if you only need the keys.
If you're doing what I think you're doing, you shouldn't be using a dictionary. The parameters you're passing to the template are already in a dictionary. If you're not going to loop over them you're better off putting the keys directly into the template parameters.
return render_to_response(t.html,
context_instance=RequestContext(request, {'aa':1, 'ab': 1, 'ac':1}))
And now it's really easy to reference them in your template.
{{ aa }}
{{ ab }}
{{ ac }}
If you do actually need to loop over an arbitrary dictionary, then AndiDog's answer is correct.
