Dynamic Selector with Django/Jquery

[Anonymous Coder]

I need to filter lists of items to be displayed upon user selection in my list view.

For instance if user selects 12 it should show only 12 products per page and so on.

My Django view has vairble items like below:

items=Items.objects.all() 

Now I need to get products as per user selection how would i do that?

<form>
<span>Show:</span>
<select class="orderby number" name="page_size">
                                               <option value="9" selected="selected">9</option>
                                               <option value="12">12</option>
                                               <option value="24">24</option>
                                               <option value="36">36</option>
                                               <option value="48">48</option>
                                               <option value="60">60</option>
                                               <option value="90">90</option>
                                               <option value="100">100</option>
</select>
</form>

Screenshot is attached. Please advise.

You can create a URL in your application to which your AJAX code will send the details and the amount of items it wants and your application will return the items in JSON format. Take a look at https://docs.djangoproject.com/en/1.11/topics/db/queries/ to learn about how to filter and limit your queries to your need.

For this specific issue:

https://docs.djangoproject.com/en/1.11/topics/pagination/

 

And quite easy to do with django.views.generic.ListView.

Add onchange="this.form.submit()".

And tie page_size to the Paginator (paginate_by attribute on ListView) through urls.py.

 

If you need more dynamic filtering (sort order / color filter etc), you

may want to look at one of these:
