我正在使用 django-select2 以模型形式表示部门（ForeignKey）。我按照文档安装了 django-select2，包括放置 {{ form.media.js }} 和 {{ form.media.css }} 标签，但由于某种原因，select2 小部件没有检索任何结果。我检查了浏览器控制台日志并显示以下错误：jQuery.Deferred exception: data is undefined S2</</HidePlaceholder.prototype.removePlaceholder@http://127.0.0.1:8000/static/assets/plugins/select2/ js/select2.full.js:4216:24
这是表单的定义
class WorkerForm(forms.ModelForm):
class Meta:
model = WorkerModel
exclude = ("id",)
widgets = {
'name':forms.TextInput(attrs={'class': 'form-control'}),
'surname1' : forms.TextInput(attrs={'class': 'form-control'}),
'surname2' : forms.TextInput(attrs={'class': 'form-control'}),
'identification':forms.TextInput(attrs={'class': 'form-control'}),
'birthday_date' :forms.DateInput(attrs={'class': 'form-control datepicker', 'autocomplete': 'off'}),
'type' :forms.Select(attrs={'class': 'form-control'}),
'department' : ModelSelect2Widget(model=DepartmentModel, queryset=DepartmentModel.objects.filter(),
search_fields=['name__icontains'],
attrs={'style': 'width: 100%;','data-placeholder':'Seleccionar'}),
'is_social_service': forms.CheckboxInput(attrs={'class': 'form-control i-checks'}),
}
这是完整的控制台日志
