django-autocompletion-light簡單外鍵完成顯示不可編輯的下拉窗口小部件

Question

我有一個國家模型：

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

    def __str__(self):
        return self.name

這是由UserDetails模型中的外鍵引用的：

    class UserDetails(models.Model):

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

通過使用django-autocomplete-light，我會發現在插入國家時，我有一個文本小部件，在寫第一個字母時完成。

因此，我准備了：

    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',
        ),
    ]

對於UserDetails表單：

    class UserDetailsForm(forms.ModelForm):

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

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

作為模板我用過：

{% 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 %}

我已將所有靜態文件復制到項目根目錄中名為“static”的文件夾中，並且我在站點設置中設置了STATIC_URL ='/ static /'。 在執行get調用時，runserver日志記錄為靜態文件提供：

[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

當我直接將get發送到自動完成視圖時，我得到了我期望的結果：

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

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

但是，如果我轉到注冊表單，對於國家/地區字段，我會得到這樣一個小部件：

這是空的，無法編輯。 如何在鍵入字母時顯示一個建議國家/地區名稱的文本小部件？

問題是我導入了一個css作為javascript文件，正在改變

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

至：

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

自動完成按預期工作。
