Django 脆 forms 'form-inline' 不能按预期工作

Question

我遵循了清晰的forms 文档，使用bootstarp4创建了一个简单的内联表单。 但似乎表单不是“内联”而是“水平” 。

这是我到目前为止的代码片段以及渲染的 web 视图的屏幕截图，

# models.py
from django.db import models


class InlineTestModel(models.Model):
    name = models.CharField(max_length=20)
    age = models.IntegerField()
    email = models.EmailField()


# form_helper.py
from crispy_forms.helper import FormHelper
from crispy_forms.layout import Submit


class FormHelperBase(FormHelper):
    form_inputs = []

    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.set_inputs()

    def set_inputs(self):
        for form_input in self.form_inputs:
            self.add_input(form_input)


class TestInlineFormHelper(FormHelperBase):
    form_class = 'form-inline'
    field_template = 'bootstrap4/layout/inline_field.html'
    layout = Layout(
        'name', 'age', 'email'
    )
    form_inputs = [
        Submit('Save', 'Save', css_class='button white')
    ]


# forms.py
from django import forms


class TestInlineForm(forms.ModelForm):
    helper = TestInlineFormHelper()

    class Meta:
        model = InlineTestModel
        fields = '__all__'


# views.py
from django.views import generic
from django.urls import reverse


class TestInlineAddView(generic.CreateView):
    model = InlineTestModel
    form_class = TestInlineForm
    template_name = 'app_name/test_inline_add.html'

    def get_success_url(self):
        return reverse('app_name:success_url')

# template
{% extends 'expenses/base.html' %}
{% load static %}
{% load crispy_forms_tags %}

{% block form_body %}
    <form method="post">{% csrf_token %}
        {% crispy form %}
    </form>
{% endblock %}

渲染 web 视图

Answer 1

问题是，我们不需要使用<form> ... </form>标签，而使用crispy标签

{% extends 'expenses/base.html' %}
{% load static %}
{% load crispy_forms_tags %}

{% block form_body %}
    
  
  
    <form method="post">{% csrf_token %} 
  
        {% crispy form %}
    
  
  
    </form> 
  
{% endblock %}

简而言之，它只需要一行，如

{% extends 'expenses/base.html' %}
{% load static %}
{% load crispy_forms_tags %}

{% crispy form %}
