FilteredSelectMultiple 小部件在 1.10.1 中不起作用（在 1.8 中起作用）

Question

我正在为 ModelMultipleChoiceField 使用来自 django.contrib.admin.widgets 的 FilteredSelectMultiple 小部件。这在我的 django 1.8 环境中效果很好，但是当我用 1.10.1 尝试它时，它无法在 select.

之后呈现 addEvent <script> 标签

来自 forms.py

class UserCatForm(forms.ModelForm):

    """Form to select Categories for user"""

    form_errors = {"required": "You must choose at least one expense category"}
    cats = forms.ModelMultipleChoiceField(
        error_messages=form_errors,
        label="",
        queryset=Categories.objects.all(),
        widget=FilteredSelectMultiple("Categories", is_stacked=False, attrs={'class':'form-control'}),
        )

    class Meta:
        name = 'UserCatForm'
        model = UserCat
        fields = "__all__"
        widgets = {'user':forms.HiddenInput(),}

工作页面源表单：

<tr><th></th><td><select multiple="multiple" class="selectfilter" id="id_cats" name="cats">
<option value="1" selected="selected">Other</option>
<option value="2" selected="selected">Education</option>
<option value="3" selected="selected">Utilities</option>
</select><script type="text/javascript">addEvent(window, "load", function(e) {SelectFilter.init("id_cats", "Categories", 0, "/static/admin/"); });</script>
<input id="id_user" name="user" type="hidden" value="1" /></td></tr>

不工作页面来源：

<tr><th></th><td><select multiple="multiple" class="selectfilter" data-field-name="Categories" data-is-stacked="0" id="id_cats" name="cats" required>
<option value="1" selected="selected">Other</option>
<option value="2" selected="selected">Utilities</option>
<option value="3" selected="selected">Education</option>
<option value="4" selected="selected">Car</option>
</select><input id="id_user" name="user" type="hidden" value="1" /></td></tr>

Answer 1

我添加了将脚本直接放入我的模板中，现在它可以工作了。

 <div class="form-group">
     {% csrf_token %}
     {{ form.as_table }}
     <script type="text/javascript">addEvent(window, "load", function(e) {SelectFilter.init("id_cats", "Categories", 0, "/static/admin/"); });</script>
 </div>

Answer 2

我找到了一种更像 django-esk 的方法来解决这个问题，我想如果有人遇到这个问题我会添加它。这适用于 1.8 和 1.10.1

我将 addEvent 调用放入外部 js 文件 ./static/js/catsfilter.js

addEvent(window, "load", function(e) {SelectFilter.init("id_cats", "Categories", 0, "/static/admin/"); });

在我的表单上创建了一个媒体子类来调用 js

class Media:
        js = ("js/catsfilter.js",)

并删除了对 core.js、SelectBox.js 和 SelectFilter2 的调用，替换为对我的 base.html 头部部分

中的表单媒体的调用

 <script type="text/javascript" src="{% static 'js/jsi18n.js' %}"></script>
 <script type="text/javascript" src="/static/admin/js/jquery.min.js"></script>
 <script type="text/javascript" src="/static/admin/js/jquery.init.js"></script>
    {{ form.media }}
