当嵌套在ArrayField中时，从Django的ChoiceField中获取人类可读的值

from django.db import models

class MyModel(models.Model):
    CHOICES = (
        ('option1', 'Option 1'),
        ('option2', 'Option 2'),
        ('option3', 'Option 3'),
    )
    
    choices = models.CharField(max_length=10, choices=CHOICES)
    array_field = models.ArrayField(models.CharField(max_length=10, choices=CHOICES))

from django import forms
from .models import MyModel

class MyForm(forms.ModelForm):
    class Meta:
        model = MyModel
        fields = ['array_field']
        
    def clean_array_field(self):
        array_field = self.cleaned_data['array_field']
        choices = dict(MyModel.CHOICES)
        human_readable_values = [choices.get(value, value) for value in array_field]
        return human_readable_values

{% for value in form.array_field.value %}
    {{ value }}
{% endfor %}
