It should be so simple. I'm following all the rules and all the answers from previous questions but it still won't happen. I have a Bottle model, that has it's own inline formset form to it's parent Wine. The date on which I bought the bottle, should show up as a standard date picker. I cannot for the life of my figure out where it goes wrong. The input type should change from "text" to "date", but it won't.

事情本应如此简单。我正在遵循所有的规则和前面问题的所有答案，但它仍然不会发生。我有一个瓶子模型，它有它自己的内联Formset形式到它的母公司Wine。我买瓶子的日期应该会显示为标准的日期选择器。我无论如何也想不出哪里出了问题。输入类型应该从“Text”更改为“Date”，但不会。

I'm using crispy forms and bootstrap 5, but disabling those also does nothing.

我使用的是易碎的表单和bootstrap 5，但禁用它们也没有任何作用。

我的型号(仅显示相关型号)：

from django.db import models
from django.conf import settings

        super(Bottle, self).save(*args, **kwargs)

    

        

My Views:

我的观点是：

from django.shortcuts import render, get_object_or_404, redirect
from django.utils import timezone
from .forms import WineForm, BottleForm
from django.forms import inlineformset_factory
from django.views.generic import ListView, DetailView, CreateView
from .models import Wine, Bottle, WineType, Country


def wine_list(request):
    wines = Wine.objects.order_by('name')
    context = {
        'wines': wines,
        # 'available_bottles': Bottle.objects.filter(available=True).count()
    }
    return render(request, 'winedb/wine_list.html', context)

def wine_detail(request, pk):
    wine = get_object_or_404(Wine, id=pk)
    bottles = wine.Bottle.all()
    context = {'wine': wine,
    'bottles': bottles}
    return render(request, 'winedb/wine_detail.html', context)


def add_new_bottle(request, pk):
    WineFormSet = inlineformset_factory(Wine, Bottle, fields=('date_bought', 'bottleprice', 'available', 'drank_on'))
    wine = Wine.objects.get(id=pk)
    formset = WineFormSet(instance=wine)
    # form = BottleForm(initial={'wine':wine})
    if request.method == "POST":
        form = BottleForm(request.POST)
        if form.is_valid():
            wine = form.save(commit=False)
            wine.save()
            return redirect('/')

    context = {'formset':formset}
    return render(request, 'winedb/bottle_form.html', context)

def add_new_wine(request):
    if request.method == "POST":
        form = WineForm(request.POST)
        if form.is_valid():
            wine = form.save(commit=False)
            wine.save()
            return redirect('wine_detail', id=wine.pk)
    else:
        form = WineForm()
    return render(request, 'winedb/wine_edit.html', {'form': form})

The form:

表格：

from django import forms
from datetime import datetime
from django.forms import ModelForm

from .models import Wine, Bottle
    class WineForm(forms.ModelForm):

    class Meta:
        model = Wine
        fields = ('producer', 'name', 'year', 'alcohol', 'grape', 'colour', 'wine_type', 'notes', 'wishlist')

class BottleForm(forms.ModelForm):
    date_bought = forms.DateField(widget=forms.DateInput(attrs={'type':'date'}))
    def __init__(self, *args, **kwargs):
        super().__init__(*args, *kwargs)

    class Meta:
        model = Bottle
        fields = ('wine', 'date_bought', 'bottleprice', 'available', 'drank_on') 

        widgets= {
            'date_bought': forms.DateInput(
                attrs={'type':'date'}), 
        }

And the template:

和模板：

{% extends 'winedb/base.html' %}
{% load crispy_forms_tags %}

{% block content %}
    <h2>New Bottle</h2>
    <form method="POST" class="post-form">{% csrf_token %}
        {% for form in formset%}
            {{ form }}
            <hr>
        {% endfor %}
        <button type="submit" class="save btn btn-secondary">Save</button>
    </form>
{% endblock %}

I have tried literally anything. From changing the format, to changing the language from US to UK in my settings and using custom widgets like:

我几乎什么都试过了。从更改格式，到在我的设置中将语言从美国更改为英国，并使用以下自定义小部件：

class DateInput(forms.DateInput):
    input_type = 'date'

UPDATE: Found the error, I should have added to attrs to the field in my view:

更新：发现错误，我应该在我的视图中添加属性到字段：

def add_new_bottle(request, pk):
    WineFormSet = inlineformset_factory(Wine, Bottle, 
        fields=('date_bought', 'bottleprice', 'available', 'drank_on'), 
        widgets= {
            'date_bought': forms.DateInput(
                attrs={'type':'date'}), 
        })
