使用 createview 在模板中将多对多字段显示为复选框

Question

查看：

class addrecipe(CreateView):
  model = Recipe
  template_name = 'recipebook/addrecipe.html'
  fields = '__all__'

型号：

class Recipe(models.Model):
  name = models.CharField(max_length=50)
  description = models.CharField(max_length=200)
  servings = models.IntegerField(default=1, blank=False)
  tools = models.ManyToManyField(Tool)

def __str__(self):
    return self.name

模板：

    {% extends 'recipeBook/base.html' %}

{% block title %}Add New Recipe{% endblock title %}

{% block header %}
<header>
  <a href="{% url 'recipeBook:recipe_list' %}">Recipe list</a>
</header>
{% endblock header %}

{% block content %} 
<h1>Add New Recipe</h1>

<form action="" method ="post">
  {% csrf_token %}
  <table>
    {{ form.as_table }}
  </table>
  <input type="submit" value="Add">
</form>
{% endblock content %}

表格：

from django import forms

from .models import Recipe, Tool

class AddRecipeForm(forms.ModelForm):
  name = forms.CharField(label="Recipe Name", max_length=50)
  description = forms.Textarea(max_length=200)
  servings = forms.IntegerField(default=1, blank=False)
  tools = forms.ModelMultipleChoiceField(queryset=Tool.objects.all(), widget=forms.CheckboxSelectMultiple, required = True)
  class Meta:
      model = Recipe
      fields = ("__all__",)

目前工具栏显示如下：

我正在尝试找到一种方法将数据库中的所有工具显示为清单，用户可以在其中简单地勾选与他们正在添加的配方相关的每个工具，或者添加一个新工具，如果它不是已经在列表中。有办法实现吗？

我需要将表单 class 添加到我的视图中，如下所示：

class addrecipe(FormView):
    form_class = AddRecipeForm
    model = Recipe
    template_name = 'recipebook/addrecipe.html'
    fields = '__all__'
    extra_context = {
        'recipe_list': Recipe.objects.all()
    }
