我的模板分为两列。
我只有一个模型,但目的是将表单分为两部分,第一列中的一部分,第二列中的另一部分。我旨在将FormHelper用于脆皮表单。

可用文档给出了一个模糊的提示,但没有任何示例,这种解释的尝试就显得有些不足。

https://django-crispy-forms.readthedocs.io/en/d-0/tags.html#rendering-several-forms-with-helpers


  用助手渲染几种形式
  
  通常我们会被问到:“如何渲染两个或多个表单,以及它们的
  各自的助手,使用{%crispy%}标签,但没有标签
  渲染两次?”容易,您需要将form_tag helper属性设置为
  在每个助手中都是错误的:

self.helper.form_tag = False

  
  然后,您将不得不编写一些围绕
  形式:

<form action="{% url submit_survey %}" class="uniForm" method="post">
    {% crispy first_form %}
    {% crispy second_form %}
</form>



更新:这篇文章解释了Crispy文档的通行证
Define crispy forms context names for two forms in one

下面是我的代码。两个FormHelper将模型分为两部分,第一部分包含字段:['car_model_make', 'status_is_secondhand']
具有字段的第二部分:['seller', 'buyer']

我一直在寻找一种“调用”特定{% crispy form %}的方法。给定“帮助”文档”,它们看起来像是{% crispy product-modelform_1 %}{% crispy product-modelform_2 %},它们不起作用。

# models.py
class Product(models.Models):
    car_model_make = models.CharField(default='B', max_length=1, blank=True, choices=CAR_TYPE)
    status_is_secondhand = models.BooleanField(blank=True)
    seller = models.CharField(max_length=50, blank=True, choices=SELLER_TYPE)
    buyer = models.CharField(max_length=50, blank=True, choices=BUYER_TYPE)

# forms.py
class ProductForm(ModelForm):
    class Meta:
        model = Product
        fields = ('__all__')

    def __init__(self, *args, **kwargs):
        super(ProductForm, self).__init__(*args, **kwargs)
        self.helper = FormHelper()
        self.helper.form_class = 'form-horizontal'
        self.helper.label_class = 'col-sm-4'
        self.helper.field_class = 'col-sm-8'
        self.helper.form_id = 'product-modelform'
        self.helper.form_tag = False


        model = 'car_model_make'
        secondhand = 'status_is_secondhand'

        self.fields[model].label = "Model"
        self.fields[secondhand].label = "Is Secondhand"

        self.helper.layout = Layout(
            Field(model),
            Field(secondhand),
            )

    def __init__(self, *args, **kwargs):
        super(ProductForm, self).__init__(*args, **kwargs)
        self.helper = FormHelper()
        self.helper.form_class = 'form-horizontal'
        self.helper.label_class = 'col-sm-4'
        self.helper.field_class = 'col-sm-8'
        self.helper.form_id = 'product-modelform'
        self.helper.form_tag = False


        seller = 'seller'
        buyer = 'buyer'

        self.fields[seller].label = "Seller"
        self.fields[buyer].label = "buyer"

        self.helper.layout = Layout(
            Field(seller),
            Field(buyer),
            )

# views.py
class ProductFormView(FormView):
    form_class = ProductForm

    def form_valid(self, form):
        form.save()
        return super().form_valid(form)

    def get_success_url(self):
        return reverse('index')

# urls.py
urlpatterns = [
    path('', index, name='index'),
    path('product/', ProductFormView.as_view(template_name='product/product.html'),


# html template

{% extends "product/base.html" %}
{% load crispy_forms_tags %}

{% block col8_content %}
<form id="product-modelform" method="post">
    {% csrf_token %}
    {% crispy form %}
    {% endblock col8_content %}
    {% block col4_content %}
</form>
    {% endblock col4_content %}
    <input type="submit" value="Submit">

最佳答案

您不能有两个__init__方法,并且实际上并不需要它。您可以借助FormHelper()将这两个“列”放在两个单独的<div>标记内。

def __init__(self, *args, **kwargs):
      super(ProductForm, self).__init__(*args, **kwargs)
      self.helper = FormHelper()
      self.helper.form_class = 'form-horizontal'
      self.helper.label_class = 'col-sm-4'
      self.helper.field_class = 'col-sm-8'
      self.helper.form_id = 'product-modelform'
      self.helper.form_tag = False
      self.helper.layout = Layout(
      Div(
        Div('car_model_make','status_is_secondhand', css_class='col-lg-6 col-md-6 col-sm-12'),
        Div('seller','buyer', css_class='col-lg-6 col-md-6 col-sm-12'),
        css_class='row'
        )
      )
