How to get value from choices in Django?

How to get a value from choices and display it on a form in Django? In this case (as in the picture), so that English is displayed, not en

Picture of form

In the template I print the form as a variable {{ form }}. I also tried to output by one field {{ form.language.get_lang_display }}, but in this case the language field is not displayed at all.

File models.py

class AvailableLanguage(models.Model):
    LANGUAGES = (
        ('en', 'English'),
        ('ru', 'Russian'),
    )
    lang = models.CharField(max_length=50, unique=True, choices=LANGUAGES)
    lang_code = models.CharField(max_length=5, unique=True)
    slug = models.SlugField()


class Question(models.Model):
    title = models.CharField(max_length=250)
    language = models.ForeignKey(AvailableLanguage, on_delete=models.CASCADE, default='')
    body = models.TextField()
    ...

File forms.py

class UserQuestion(forms.ModelForm):
    class Meta:
        model = Question
        fields = ('title', 'language', 'body')

File add_question.html

{% block content %}
    <form action="." method="post" enctype="multipart/form-data">
{#        {{ form }}#}
        {{ form.language.get_lang_display }} {#Not displayed#}
        {% csrf_token %}
        <input class="btn--primary" type="submit" value="{% trans 'Создать' %}">
    </form>
{% endblock %}

use

{{ form.get_lang_display }}

instead of

{{ form.language.get_lang_display }}

Just return a str function from your AvailableLanguage model:

class AvailableLanguage(models.Model):
    LANGUAGES = (
        ('en', 'English'),
        ('ru', 'Russian'),
        )
    lang = models.CharField(max_length=50, unique=True, choices=LANGUAGES)
    lang_code = models.CharField(max_length=5, unique=True)
    slug = models.SlugField()

    def __str__(self):
        return self.get_lang_display()
