Question

我有一个国家模型：

    class Country(models.Model):
        name = models.CharField(max_length=200)

    def __str__(self):
        return self.name

这是由UserDetails模型中的外键引用的：

    class UserDetails(models.Model):

        ...
        country = models.ForeignKey(Country,verbose_name='Country',null=True, blank=True, default = None)

通过使用django-autocomplete-light，我会看到插入国家时我有一个文本小部件，在写第一个字母时完成。

因此，我准备了：

    class CountryAutocomplete(autocomplete.Select2QuerySetView):
        def get_queryset(self):

            qs = Country.objects.all()

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

        return qs

使用urls.py：

    app_name='shared'
    urlpatterns = [
        url(
            r'^country-autocomplete/$',
            CountryAutocomplete.as_view(),
            name='country-autocomplete',
        ),
    ]

对于UserDetails表单：

    class UserDetailsForm(forms.ModelForm):

        country = forms.ModelChoiceField(
            queryset=Country.objects.all(),
            widget=autocomplete.ModelSelect2(url='shared:country-autocomplete')
            )

        class Meta:
            model = UserDetails
            fields = [...,"country"]

作为我使用的模板：

{% load static %}


{% block content %}
<form method="post" action=".">
    {% csrf_token %}
    {{ user_form.as_p }}
    {{ user_details_form.as_p }}
    <input type="submit" value="Submit" />
</form>
{% endblock %}

{% block footer %}
    <script type="text/javascript" src="{% static 'admin/js/vendor/jquery/jquery.js' %}"></script>
    <link rel="stylesheet" type="text/css" href="{% static 'autocomplete_light/select2.css' %}" />
    <script type="text/javascript" src="{% static 'autocomplete_light/jquery.init.js' %}"></script>
    <script type="text/javascript" src="{% static 'autocomplete_light/autocomplete.init.js' %}"></script>
    <script type="text/javascript" src="{% static 'autocomplete_light/select2.js' %}"></script>
    <script type="text/javascript" src="{% static 'autocomplete_light/vendor/select2/dist/css/select2.css' %}"></script>
    <script type="text/javascript" src="{% static 'autocomplete_light/vendor/select2/dist/js/select2.full.js' %}"></script>
    <script type="text/javascript" src="{% static 'autocomplete_light/forward.js' %}"></script>
    <script type="text/javascript" src="{% static 'admin/js/vendor/jquery/jquery.js' %}"></script>
    {{ form.media }}
{% endblock %}

我已将所有静态文件复制到一个名为＆＃39; static＆＃39;的文件夹中。在项目的根目录中，我设置了STATIC_URL =＆＃39; / static /＆＃39;在网站设置中。在执行get调用时，runserver日志记录提供了静态文件：

[23/Oct/2016 17:44:59] "GET /accounts/register/ HTTP/1.1" 200 2344
[23/Oct/2016 17:44:59] "GET /static/admin/js/vendor/jquery/jquery.js HTTP/1.1" 304 0

[23/Oct/2016 17:44:59] "GET /static/admin/js/vendor/jquery/jquery.js HTTP/1.1" 304 0

当我将get直接发送到自动完成视图时，我得到了我期望的结果：

http://127.0.0.1:8000/shared/country-autocomplete/?q=u

{"pagination": {"more": false}, "results": [{"text": "USA", "id": 3}]}

但是，如果我转到注册表单，对于国家/地区字段，我会得到这样的小部件：

这是空的，无法编辑。如何在输入字母时有一个建议国家/地区名称的文本小部件？

问题是我将css导入为javascript文件，改变

<script type="text/javascript" src="{% static 'autocomplete_light/vendor/select2/dist/css/select2.css' %}"></script>

为：

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

自动完成工作正常。

django-autocompletion-light简单外键完成显示不可编辑的下拉窗口小部件
