jQuery Filedownload EZ Exporter Shopify App

Our Shopify app, EZ Exporter, provides an option for users to download reports on demand from the app's main page. Since it could take some time to generate the report in the background depending on the data, we needed a way to let the user know that the task is currently in progress so they don't reload the page or do something else thinking that nothing is happening. We also wanted to block ...

Adding responsive tables (no scrollbars) to your Django app with DataTables

January 13, 2015

It had been over year since I last looked at DataTables, a jQuery table plugin for creating tables with advanced features. I used it for my Django app, GlucoseTracker, and it worked great. But one thing that was bothering me was it wasn't responsive. It was the only element in my app that wasn't responsive and looked horrible when viewing on a phone in portrait mode.

Over the weekend I decided to check ...

Adding drag and drop image uploads to your Django site in 5 minutes with DropzoneJS

How to submit a form in a POST request using JavaScript

April 16, 2013

I was working on a Django project a couple of days ago where I needed to use JavaScript to submit a form in a POST request. The response of this request is a PDF file generated with ReportLab. I wanted the browser to prompt the user to download the file or open it in the browser in another window.

I was trying to do this with AJAX at first, but apparently you’re not really ...

GWT, Django, and JSON (with padding)

August 8, 2011

A couple of months ago I was working on a project where I needed to retrieve data in JSON format from a web service written in Python (using the Django web framework) under GWT. The data is then loaded into GXT/Ext GWT grids and charts.

After looking at a GXT example of loading JSON data to a grid, I thought this would be pretty straightforward, but of course I was wrong. Since the Django ...
