Django forms.ChoiceField is always changed

Django==1.10

I want to use a models.BooleanField as a forms.ChoiceField in the admin app.

models.py

from __future__ import unicode_literals
from django.db import models

class MyModel(models.Model):
    name = models.CharField(max_length=255)
    bool_field = models.BooleanField()

admin.py

from django.contrib import admin
from .models import MyModel
from .forms import MyModelForm

@admin.register(MyModel)
class TemplateAdmin(admin.ModelAdmin):
    form = MyModelForm
    list_display = ['name','bool_field']

forms.py

from django import forms

class MyModelForm(forms.ModelForm):
    bool_choices = ((True, "Yes"),(False, "No"))
    bool_field = forms.ChoiceField(choices=bool_choices)

Everything displays just like I want, but in fact every time I save the instance the History link shows that the bool_field was changed even if it wasn't.

I tried to change the bool_field to TypedChoiceField with coerce=bool, but it doesn't work well. After I change and save the instance the value remains the same.

Please advise what I should probably change in order to get History working right.

Try and specify that the bool_field is not required, like so:

bool_field = forms.ChoiceField(choices=bool_choices, required=False)
