How access verbose_name of a field in template?

How access verbose_name of a field in template?

I have an object:

p = Person.objects.get(pk=1)

and I wanna access same verbose_name in template like it:

<span>{{ p.name.__verbose_name }}: {{ p.name }}</span>
<span>{{ p.birth_date.__verbose_name }}: {{ p.birth_date }}</span>

result:

Name: Maria

Birth date: 1990-04-07

How I do it? Have some way of access verbose_name? I am using Django 1.8

I would write a view which collects the verbose names and other wanted
info and put it all into a single object or dict and pass that into the
template, like ...

obj.name_verbose_name
obj.name
obj.birth_date_verbose
obj.birth_date

The idea is to keep your templates simple and do anything less simple in
python code in the view. There are two reasons being 1) it is faster and
2) non-programmers can tweak templates without bothering you.

If is to do that way, I prefer to do manually. I would like to access the direct verbose_name the template. Is possible that the "Django developers" could do this?

You could write up a simple template tag (or even a template filter) to do this.

https://docs.djangoproject.com/en/1.8/howto/custom-template-tags/#simple-tags

Something along these lines would probably work:

# templatetags.py

register = template.Library()

@register.simple_tag

def verbose_name_tag(obj, field_name):

    return obj._meta.get_field(field_name).verbose_name

@register.filter

def verbose_name_filter(obj, field_name):

    return obj._meta.get_field(field_name).verbose_name

# in template.html

{% load mytemplatetags %}

{# template tag #}

<span>{% verbose_name_tag p 'name' %}: {{ p.name }}</span>

<span>{% verbose_name_tag p 'birth_date' %}: {{ p.birth_date }}</span>

{# template filter #}

<span>{{ p|verbose_name_filter:'name' }}: {{ p.name }}</span>

<span>{{ p|verbose_name_filter:'birth_date' }}: {{ p.birth_date }}</span>

Untested, although I don't see why it wouldn't work. I have similar tags built for the verbose_name and verbose_name_plural of the object itself.

You would need to decide whether a tag or filter is more readable, although I would personally choose a tag this in this case. You may also want to make the tags a bit more resilient against bad field names, etc.
