姜戈脆皮形式； 不加载按钮

Question

I'm just have an issue with Crispy Forms; I cannot get a button to load. I've checked a ton of other StackOverflow forms, but all the examples I've followed, nothing seems to work.

example forms.py

from crispy_forms.helper import FormHelper
from crispy_forms.layout import Submit

from django import forms

from .models import ExampleModel

class ExampleModelForm(forms.ModelForm):
    def __int__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.helper = FormHelper()
        self.helper.add_input(Submit('submit', 'Submit'))

    class Meta:
        model = ExampleModel
        fields = ['content', 'title']

example views.py

from django.shortcuts import render
from django.http import HttpResponseRedirect

from .forms import ExampleModelForm

def get_form(request):
    if request.method == 'POST':
        form = ExampleModelForm(request.POST)
        if form.is_valid():
            return HttpResponseRedirect('/success/')

    else:
        form = ExampleModelForm()

    return render(request, 'example_form.html', {'form': form})

example example_form.html

{% extends 'base.html' %}

{% load crispy_forms_tags %}

{% block content %}
    {% crispy form %}
{% endblock %}

My form loads beautifully, but I just cannot get the button to show. I've looked at the docs and I don't see what I am doing differently. Maybe it just doesn't play well with ModelForms? I don't know.

I've tried changing the location of def__init__... to be below the Meta class. I defined super() to be super(ExampleModelForm, self) and self.helper = FormHelper(self) .

I even tried to change {% crispy form %} to {% crispy form form.helper %} in the html file. It just breaks.

I tried following this example too. Just nothing is working for me.

Settings:
Django: 3.2.5
Crispy-Forms: 1.12.0

Ok I figured this out, but I don't know why it behaves like this.

class ExampleModelForm(forms.ModelForm):
    helper = FormHelper()
    helper.add_input(Submit('submit', 'Submit'))

    class Meta:
        model = ExampleModel
        fields = ['content', 'title']

Basically you don't need the def__init__(... Could someone explain this to me?
