dropdown_filter in django

[Sachin Tiwari]

Hi,

I want to make my custom filter into drop down filter,

class PersonIdFilter(SimpleListFilter):

    title = _('Personid')

    parameter_name ='personid'

    contlist = list(PersonInfo.objects.all())

    def lookups(self, request, model_admin):

        lst = []

        for id in self.contlist:

            lst.append((id.personid,id.personid))

        return tuple(lst)

    def queryset(self, request, queryset):

        if self.value() is None:

            return queryset

        return queryset.filter(personid__exact=self.value())

class PersonAdmin (admin.ModelAdmin):

       list_filter = (PersonIdFilter,)

The above filter is working for me, but I want to convert it into dropdown filter 

I tried with below approach 

Create a class in filters.py 

from django.contrib.admin.filters import AllValuesFieldListFilter

class DropdownFilter(AllValuesFieldListFilter):

    template = 'admin/dropdown_filter.html'

Create a template in templates/admin/dropdown_filter.html

Copied from fiencms

{% load i18n %}

<script type="text/javascript">var go_from_select = function(opt) { window.location = window.location.pathname + opt };</script>

<h3>{{ title }}</h3>

<ul class="admin-filter-{{ title|cut:' ' }}">

{% if choices|slice:"4:" %}

    <li>

    <select style="width: 95%;"

        onchange="go_from_select(this.options[this.selectedIndex].value)">

    {% for choice in choices %}

        <option{% if choice.selected %} selected="selected"{% endif %}

         value="{{ choice.query_string|iriencode }}">{{ choice.display }}</option>

    {% endfor %}

    </select>

    </li>

{% else %}

    {% for choice in choices %}

            <li{% if choice.selected %} class="selected"{% endif %}>

            <a href="{{ choice.query_string|iriencode }}">{{ choice.display }}</a></li>

    {% endfor %}

{% endif %}

And in my admin.py

from receivedata.filters import DropdownFilter

class PersonAdmin (admin.ModelAdmin):

       list_filter = (PersonIdFilter,DropdownFilter)

Error : type object 'PersonIdFilter' has no attribute 'split'

But it did not works for me,please suggest some other way

Hi Sachin,

Interesting. It seems to me that should work. Could you post a traceback?

Thanks,

Collin

Hi Collin,

It works when I comment the filters.py

and change admin.py as below,

 

from receivedata.filters import DropdownFilter

class PersonAdmin (admin.ModelAdmin):

       list_filter = (PersonIdFilter)

Thanks & Regards,
