These functions use JQuery to dynamically add new entries for stacked or tabular inlines on a change form. To enable it, change the parent model to include this Javascript as well as JQuery. Here's an example: class MeetingAdmin(admin.ModelAdmin): inlines = [MeetingDonationInline, MeetingExtraInline] class Media: js = ["/media/jquery-1.3.2.min.js", "/media/dynamic_inlines.js"]
This filter converts HTML to nicely-formatted text using the text-browser W3M. I use this for constructing e-mail bodies, since it means I don't have to have two templates, one HTML and one plain-text, for each detailed e-mail I want to send. Besides the obvious maintenance benefits, this is nice because Django's templating system isn't well-suited to plain-text where whitespace and line-breaks are significant. I chose W3M because it renders tables nicely and can take in HTML from STDIN (which Lynx can't do). An alternative is ELinks; to use it, change "cmd" to the following: `elinks -force-html -stdin -dump -no-home`
Here's some fairly normalized models for representing postal addresses. Making postal_code a separate model would probably be the only way to get it to a level that everyone would agree is 2NF, but we handle a lot of international addresses so that isn't really feasible. Country and StateProvince are intended to be populated with data from ISO 3166. I'd include the SQL I used with that data, but it's very long and there's no attach feature. Also, I'd probably be violating ISO's copyright.
This is an example of a view that returns an Excel spreadsheet; the last ~7 lines are the relevant ones. It relies on Excel's ability to automatically import HTML (see http://support.microsoft.com/kb/165499 for more info). The spreadsheet.html template is just has one big `<table>` tag with all the data as table cells (no `<html>` or other surrounding tags are necessary).
Alternative version of newform code for handling credit cards. Unlike the other two credit-card snippets (http://www.djangosnippets.org/snippets/764/ and http://www.djangosnippets.org/snippets/830/), this uses two drop-down boxes instead of text fields for the expiration date, which is a bit friendlier. It doesn't do as much checking as snippet #764 since we rely on the payment gateway for doing that. We only accept Mastercard, Visa, and American Express, so the validation code checks for that.
