I will change a model form widget attribute without define the complete field. Because many "meta" information are defined in the model (e.g. the help_text) and i don't want to repeat this. I found a solution: Add/change the widget attribute in the __init__, see example code.
This class not only checks an old-style phpbb 2.x password, when the user successfully logs in, it rehashes the (correct) password in the newstyle hash and saves it. Eradicating the old, quite unsafe stored md5 password.
Displays as an ordinary selectbox with an additional text-input for filtering the options. An adaption of the example at [1] for use with Django. The code assumes the java script from [2] is downloaded into your media folder. Remember to output your form's media, for instance like: "{{form.media|safe}}", somewhere above your form. **License:** [2] by Mr Patrick Fitzgerald is licensed under GPL and the python code written by myself is GPL as well. **References:** 1. http://www.barelyfitz.com/projects/filterlist/index.php/ 2. http://www.barelyfitz.com/projects/filterlist/filterlist.js
To create a lower entry barrier to logging into our intranet I created a very simple backend using Google Apps Premium provisioning API (http://code.google.com/apis/apps/gdata_provisioning_api_v2.0_reference.html). This enables controlling access for your users based on their status in your Google Apps instance. *(NOTE! Since the provisioning API is only available in the Premium version of Google Apps you first need to upgrade if you haven't done so already)* Requirements: You need Google Data libraries for python. They can be downloaded from http://code.google.com/p/gdata-python-client/downloads/list Google Apps Premium -- User used by the script must have admin rights
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).
Rather than using the full GZipMiddleware, you may want to just compress some views. This decorator lets you do that. @gzip_compress def your_view(request, ...): ....
This is a simple middleware that redirects the exactly URL requested with the correct domain. It is useful when you have more than one domain (most of cases with "www." or IP) to access a website. To make it works, download the snippet file as the name "permanent_redirect.py" and add its path as the first item in MIDDLEWARE_CLASSES setting in settings.py. Later you must inform a setting called `HTTP_HOST_DOMAIN` with the correct domain.
this is an enhancement to paulsmith's code snippet 190, to provide an extra "search by distance" parameter rather than "limit number of results returned". i need this for a social networking site where users can search for people within a certain geographical area.
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.
This code improves on Django's render_to_response shortcut function in the following ways: 1. If the caller does not provide a MIME type, and the caller is passing a RequestContext, it interrogates the request to determine if the HTTP client supports application/xhtml+xml encoding. If so, it sets the request type to application/xhtml+xml to override the HttpRequest class's default mime type of text/html. 2. It caches parsed templates in its own cache to improve performance. If you aren't using XHTML in your templates, you may choose to comment out the code that tests for and sets the application/xhtml+xml MIME type. I place this code in a file named "util.py" in my application. In my views, I write "from app.util import render_to_response" where I used to write "from django.shortcuts import render_to_response". Note that the caching functionality provided by this code means that you will need to recycle your Django instance when you make template changes. Instructions for doing this depend on how you have deployed your Django application.
Add this method to any model to make it clonable.
This ModelAdmin class sets fields for models saved in admin corresponding to the user that created the object and the user that last updated the object. Trivial for the current model, but a little more involved to make it work with inlines. The fields still show up as drop-downs (`select`) in the admin, but I fixed that with a little jQuery: $(function(){ $("select[id*='creator'], select[id*='updater']").each(function(){ var user = $('option:selected', this).text(); $(this).siblings('.add-another').hide(); $(this).hide(); $(this).after(user); }); }); This could easily be subverted, but with trusted users, it makes for a quick and dirty read-only field.
I recently needed to sort a list of objects by cardinal direction clock-wise. Since this is different than alphabetical, and I didn't want to use a dictionary to map to integers, here is what I came up with. There may be a cleaner way to do this by overriding some object methods, but I just thought I'd put this out there anyway.
I had some trouble getting other peoples code to work for AD support, so I wrote my own which authenticates against LDAP and will also use SSL and cert if required. It will also verify that an autheticated user has specific group membership before authorizing. This will also debug to a file, which is really helpful when trying to figure out problems. One thing that really got me when getting python-ldap to work was that you must have "ldap.set_option(ldap.OPT_REFERRALS,0)" set or any ldap search will not work. Also, this will add group permissions to a user.
