django - DAL-yl 未定义

Question

我正在尝试实现以下自动完成功能 django-autocomplete-light tutorial
我可以确认自动完成 View 已成功创建，直接输入 url，如下所示。
但是，当我使用表单 View 进行测试时，自动完成功能不起作用并在控制台中出现以下错误。

Uncaught ReferenceError: yl is not defined

有谁知道是什么原因导致这个问题以及如何解决这个问题？

html页面

    {% extends "base.html" %}
    {% load crispy_forms_tags %}
    {% crispy document_form document_form.helper %}
    {% load staticfiles %}

    {% block content %}
<script src="{% static 'vendor/js/select2.js' %}"></script>
    <link rel="stylesheet" type="text/css" href="{% static 'css/form.css' %}" />
    <link rel="stylesheet" type="text/css" href="{% static 'vendor/css/select2.css' %}" />
        <h3>Upload Project</h3>
        {% crispy form %}


    {% endblock %}  

forms.py

from django import forms
from project.models import html
from django.forms import widgets
from crispy_forms.helper import FormHelper
from crispy_forms.layout import Submit
from dal import autocomplete

class DocumentForm(forms.ModelForm):

    def __init__(self,*args,**kwargs):
        super(DocumentForm,self).__init__(*args,**kwargs)
        self.helper=FormHelper(self)
        self.helper.form_id='projectForm'
        self.helper.form_method='post'
        self.helper.add_input(Submit('submit', 'Submit'))

    class Meta:
        model=html
        fields=['project','version','diff','program','location','certificate','user','html','idf','eso']
        wdigets={
            'project':autocomplete.ModelSelect2(url='project:project-autocomplete')
        }

class ProjectAutocomplete(autocomplete.Select2QuerySetView):
    def get_queryset(self):
        qs=html.objects.all()

        if self.q:
            qs=qs.filter(project__istartswith=self.q)

        return qs

Answer 1

您缺少静态文件，而不仅仅是 select2.js。你应该拥有所有这些: CSS

    <link rel="stylesheet" type="text/css" href="{% static 'vendor/select2/dist/css/select2.css' %}">
    <link rel="stylesheet" type="text/css" href="{% static 'autocomplete_light/select2.css' %}">

JS

    <script src="{% static 'autocomplete_light/jquery.init.js' %}"></script>
    <script src="{% static 'autocomplete_light/autocomplete.init.js' %}"></script>
    <script src="{% static 'vendor/select2/dist/js/select2.full.js' %}"></script>
    <script src="{% static 'autocomplete_light/select2.js' %}"></script>
    <script src="{% static 'autocomplete_light/forward.js' %}"></script>
    <script src="{% static 'autocomplete_light/jquery.post-setup.js' %}"></script>

这是自动完成功能需要出现在最后一页上的内容，但将它们添加到模板的正确方法应该是在模板中包含此变量

{{ form.media }}

这应该可以解决问题:-)
