Django, best way to print a field key - django

Question

I want to print fields of a model differently than by first_name
I want to print something like "key: value" but it prints "first_name: Georges", I would prefer that it's looks like "First name: Georges"
Currently i'm using a file named form.html that I include in every form template:
{% load widget_tweaks %}
{% for field in form %}
<div class="form-group">
{{ field.label_tag }}
{% if form.is_bound %}
{% if field.errors %}
{% render_field field class="form-control is-invalid" %}
{% for error in field.errors %}
<div class="invalid-feedback">
{{ error }}
</div>
{% endfor %}
{% else %}
{% render_field field class="form-control is-valid" %}
{% endif %}
{% else %}
{% render_field field class="form-control" %}
{% endif %}
{% if field.help_text %}
<small class="form-text text-muted">
{{ field.help_text }}
</small>
{% endif %}
</div>
{% endfor %}
And a model that looks like this:
from django.db import models
class Person(models.Model):
first_name = models.CharField(max_length=30)
last_name = models.CharField(max_length=30)
What is the best way to print first_name as "First name"?:
Is it by setting verbose_name for every fields in the models.py?
Or by setting label in the forms.py for every fields in each form?
Or by not using a dynamic template and hardcode it in my form.html?

Answer 1

Like what Aleksei Maide said to change that you need to alter the Label, here is an example:
in your form class add a method:
def __init__(self, *args, **kwargs):
super(YourFormName, self).__init__(*args, **kwargs)
self.fields['first_name'].label = "First name"
this is how i'm displaying it in my template:
<label class="bmd-label-static">{{ field.label }}</label>
{{ field.name }}

Think by a moment that you have a Model Form with 30 fields, and as this form, you have other 30 more Model Forms, now, you have to set every time your field labels, is a very complicated task, don't you think?
i could suggest you that use the verbose name feature to each model field and build a simple template tag that can help you to get dinamicaly the verbose name of your fields i your templates
This template tag will try to get the model field's verbose name
# yourapp/templatetags/yourapp_extras.py
from django import template
register = template.Library()
#register.simple_tag
def field_name(model, field):
field_name = field
if model:
try:
field_name = model._meta.get_field(field).verbose_name.title()
except Exception as ex:
print ex
return field_name
And in your template you can display your field label as follow
# sometemplate.html
{% load widget_tweaks %}
{% load yourapp_extras %}
{% for field in form %}
<div class="form-group">
{% field_name model field.name %} <!-- here -->
{% if form.is_bound %}
{% if field.errors %}
{% render_field field class="form-control is-invalid" %}
{% for error in field.errors %}
<div class="invalid-feedback">
{{ error }}
</div>
{% endfor %}
{% else %}
{% render_field field class="form-control is-valid" %}
{% endif %}
{% else %}
{% render_field field class="form-control" %}
{% endif %}
{% if field.help_text %}
<small class="form-text text-muted">
{{ field.help_text }}
</small>
{% endif %}
</div>
{% endfor %}
