Shifting Bits Makes Progress
I have done a little more hacking on Shifting Bits this weekend and have launched a beta version of it: http://beta.paltman.com In order to keep crawlers and indexers out of it and not leaving it up to trusting that they obey a good robots.txt instruction set, I have put some simple low-tech authentication on it (HTTP Basic). The username and password for this beta site is paltman/test. I'd love to hear any feedback about what's there. This was mainly a test to get my environment where it needed to be to host the blog as well as to exercise my Wordpress import tool somewhere other than my laptop. -
The Django Debug Un-Toolbar
When I caught wind of the Django Debug Toolbar a couple weeks ago, I was really excited to put it to use. However, when i wired it up, I discovered that it wasn't going to play nicely with MooTools since it is based on jQuery. Not being a javascript expert, I am assuming there is some global namespace collisions in how the two libraries use shortcut functions like the dollar sign selectors (e.g. $('some-dom-element')). Anyway, the more I thought about it, I figured it probably best to not manipulate the DOM at all. In some discussion with others, it was determined a very useful adaptation to the project would be to serialize off all the data collected in the middleware on the server and set a cookie to a special path so that it could be retrieved via something like a bookmarklet. So that's what I did. I forked the Django Debug Toolbar project and renamed it to Django Debug Un-Toolbar, real original, I know. While I don't expect it to be perfect yet (I spent about 2 hours this evening making sweeping and hurried changes to the code base), it does work as intended. There are a number of … -

HTTP 200 testing Django applications with Facebook
I've been writing a simple Django application for Facebook these days. I'm really enjoying how clean Django's code is and its very well thought classes and methods. It really makes web development faster. I started with some simple HTML running locally on Django's development server and then updated my templates to output FBML based on the value of a variable I called IN_FACEBOOK and inserted into my settings.py. After adding PyFacebook to talk to Facebook's API from Python I configured my new application according to Facebook's instructions. Finally I changed my router's port forwarding settings to allow Facebook to see my home server's public IP, which is dynamic and provided by my ISP. Everything ran ok up to this point and then I started noticing that after each change on my application's code Facebook returned a blank page with an HTTP 200 message. It seemed like a connection issue and I moved the application to my real server, which has a fixed public IP, but the problem persisted. After every code change Facebook returned a blank page with the HTTP 200 message. I needed to refresh the browser three or more times to get my application loading. My application is … -

Getting Django up and running on Centos 5.2 with Apache(mod_python) and MySQL
This is partly for my reference (doing it the second time just now and I forgot everything!) but hopefully it will be helpful for others too. Disclaimer; I am by no means a Linux expert. This is just how I got it working... If there is a better, easier or wiser way please let me know! Let's assume you have Yum installed (I didn't on my VPS - but my provider installed it for me). First, make sure you are up to date; $ yum update These are the packages I installed (httpd and python are already installed); mod_python (Apache uses this to run Python) mysql-server mysql-devel (easy_setup needs this) python-devel (easy_setup needs this) python-setuptools (so we have easy_setup) gcc (easy_setup needs this) $ yum install mod_python mysql-server mysql-devel python python-devel python-setuptools gcc At this point I would have added MySQL-python to this list, however the default repo's I have only give me version 1.2.1 and Django needs 1.2.1p2 or later. The easiest way I found to get this was with easy_install but it requires a few other packages as mentioned above. After that is finished you can go on to install MySQL-python by doing this; $ /usr/bin/easy_install MySQL-python This … -
Hacking Django forms for CSS flexibility
The default output of the Django forms (former newforms) module is not very CSS friendly. With a few simple adjustments, you can make your web designer colleague happy. This patch will add three classes on the parent HTML element of the rendering of each form field (the tr, li or p tag depending on your rendering mode): The type of the form field. (Examples: CharField, ModelChoiceField) The type of the widget. (Examples: TextInput, SelectInput) Is the form field optional or required: Optional or Required Now a required DateField will render, using the as_table rendering, as: <tr class="DateField TextInput Required"> <th> <label for="id_date">Date</label> </th> <td> <input type="text" name="date" id="id_date" /> </td> </tr> Example uses A couple of example use cases where my patch will help you out: Special styling of required fields possible. Easier to add a date picker by JavaScript. Special styling of checkboxes (styling input elements to width: 100% also affects those).

Django ModelForm - replacement for form_for_model & form_for_instance
Each commit, Django gets more amazing.I wrote about newforms library before. The library was a big step in Django form displaying and validating.The first approach was to use forms.form_for_model() and forms.form_for_instance() respectively.As Django programmer I found this a little confusing. Both were similar. The only difference was that form_for_instance() took an object instance for saving -
Custom Actions In Django Admin Object Editor
I’ve seen many posts asking for the simplest feature in Django admin… the ability to add custom actions next to History and View On Site in the Django admin form. The page where the actual object is edited, not the list pages. Imagine adding actions like: Edit Next Item Edit Previous Item Send Thank You Email Export [...] -

Django -> Plone: Portlets, Viewlets, Zcatalog, Aspects
[Another in a series of posts about moving from Django to Plone. I'm a Plone/Zope newbie writing about my bafflements and enlightenments as they happen. Some of my opinions are certainly wrong. I'm writing this in the expectation that the history of my meandering learning path may be useful, or at least entertaining, to future Plone [...] -
Django browser for Redmine database
Do you know redmine ? This is, to my knowledge, the best project manager you could ever find out there. I like to describe it as ‘trac done well‘. It has only one, big, ugly, fat inconvenient for me : it is written on top of ruby on rails. I could tell you how slow [...] -
Django JQuery Autocomplete for Model Selection
I’ve been working on a very cool snippet, inspired by Django Autocomplete Widget : http://www.djangosnippets.org/snippets/233/ The idea is to create a Widget containing the client side code (I mean html + jquery), and a custom field called ModelAutocompleteField that accepts any model as a contructor parameter and its clean method returns the instance selected by [...] -

django and some plone
There seems to be some rumblings on the Plone front for us currently. For our main stable of development however, we have moved away although not totally from Plone to django. The main reason here is that for Plone deals to be feasible for us, we either have to:1. Lock requirements down really tight so that the juniors can have a go at it .... or 2. Sic some seniors at it.In my own experience, it seems that while Plone can be easy if worked within a tight parameter, try swaying a bit out of those parameters, when you have to peer under the hood and you are in a world of pain. It's hard to gain leverage using Plone this way. django on the hand has been actually quite young developer friendly for us and they end up being actually more productive compared to when they are forced to make some funky changes in Plone. Most of the business applications that we build require a light framework and is normally built from ground up. This means that Plone is sometimes an overkill for these apps which is a shame because Plone almost always appear like a good fit in … -

10. Finishing the Code-Sharing Application
This is part 10 of a series of posts on James Bennett's excellent Practical Django Projects. The table of contents and explanation can be found here Finally, we're on the home stretch. This chapter builds on our knowledge of templates and also gives a few new examples of custom template tags, so without further ado lets finish the app. On p188 you need to modify the save method of the bookmark -
9. Form Processing in the Code-Sharing Application
This is part 9 of a series of posts on James Bennett's excellent Practical Django Projects. The table of contents and explanation can be found here The chapter is the first serious coverage of forms. As Django 1.x has been released there is no old and newforms just forms, so on p171 and p176 and wherever else from django import newforms as forms is used, just use from django import forms. There -
Mark Ramm: Django and learning from Zope 2
Mark Ramm gave an interesting talk (now up on youtube) at DjangoCon about learning from the experiences of Zope 2. As someone who hit the Z productivity wall after developing a site with Zope 2 I really appreciated what he had to say but disagree with the reasons for the decline of Zope 2 and what it means for Django. The first part of the talk he summarizes as:"basically an argument that -
Django Tabbed Admin
A while ago i was playing with the excellent pinax (django-hotclub) project and i felt like the admin index page was kind-of overwhelming due to all the different apps listed in it. So i put a simple app together that has one template tag and a slight modification of the "admin/index.html" template to create simple tabs in the django admin interface. To minimize my effort ;-) i used jquery and ui.tabs.js to create the tabs at runtime. With one mandatory tab called "main" (changeable in settings.py), which contains all apps not mapped to a specific tab, and an attribute in settings called "ADMIN_TABS" that maps different apps to different tabs. It's still more-or-less a proof-of-concept applicatio, but it shows how easy these kinds of modifications can be in the django admin interface. Screenshots Mercurial repository Afterthoughts: I would like to extend this to something like shown in the Gondola screencast by Peter Baumgartner at a later time where a specific tab can also short-cut to common usage patterns. -
Django -> Plone: Light Bulbs, differences, irks
[This continues from my first post about my Django-to-Plone odyssey.] I now understand more of Plone‘s underlying concepts. I can’t yet create a non-trivial Plone site from scratch in a reasonable amount of time, but I’m getting closer. I’ve read some of, and have temporarily put aside, Professional Plone Development. I’ve read a few of the on-line tutorials [...] -
