txt2img tag shows on the web text as images, helping to avoid get indexed email address and some other information you don't want to be on search engines. Usage: `{{worker.email|txt2img:18|safe}}`
A CompressedTextField to transparently save data gzipped in the database and uncompress at retrieval. Full description at my blog: [arnebrodowski.de/...Field-for-Django.html](http://www.arnebrodowski.de/blog/435-Implementing-a-CompressedTextField-for-Django.html)
This snippet is a template filter based on ["truncate letters"](http://www.djangosnippets.org/snippets/126/) only it will either truncate or pad a string to ensure the output is always a set width.
**Credit goes to** [Andrew Gwozdziewycz](http://www.23excuses.com/2006/Jun/30/simple-django-view-for-dynamic-text-replacement/) and [Jacob Kaplan-Moss](http://www.jacobian.org/writing/2006/jun/30/improved-text-image-view/) This is basically their code. Only differences: * orientation can be customized * size can be customized * GIF-Image with transparency is created Note: Because of the minimum palette that's used, the font isn't antialiased/smoothened. My url for this view looks like so: (r'^img/(?P<fontalias>\w+)/(?P<orientation>(normal|left|right))/$', 'view.text_to_image')
Convert plain text to html. For example: text="""aabhttp://www.example.com http://www.example.com http://www.example.com <<< [<aaaa></aaaa>] """ print plaintext2html(text) It can convert url text to html href. And it also can convert space to . So if you paste python code, the indent will not lost at all. Default it'll convert \t to 4 spaces.
This snippet *updates* http://www.djangosnippets.org/snippets/383/ and http://www.djangosnippets.org/snippets/1495/ for Django 1.4+, and adds support for sqlite3 and south. Original snippet text: A CompressedTextField to transparently save data gzipped in the database and uncompress at retrieval.
I found my self doing data migration for a client, and also found that their old system (CSV) had 4 text fields that were 2 to 4MB each and after about 2 minutes of hammering the mysql server as I was parsing this and trying to insert the data the server would drop all connections. In my testing I found that if I didnt send those 4 fields the mysql server was happy to let me migrate all my data all (240GB of it). So I started thinking, "I should just store these fields compress anyways, a little over head to render the data, but thats fine by me." So thus was born a CompressedTextField. It bz2 compresses the contents then does a base64 encode to play nice with the server storage of text fields. Once I started using this my data migration, though a bit slower then without the field data, ran along all happy.
Custom field for using MySQL's `text` type. `text` is more compact than the `longtext` field that Django assigns for `models.TextField` (2^16 vs. 2^32, respectively)
Small example of how to write your own function. This is not available in Django. The function just replaces static text strings, regular expressions are not supported. The syntax is the same in SQLite, PostgreSQL, MySQL and Oracle.
How to use: {% load highlight %} {{ text|highlight:'word' }}
Yeah, I know this is a very basic filter, but I thought I might as well share it with the world...
this will turn ikfjji34 iojwe# eijdf#@$iojdfg 234oijdfg into ikfjji_iojwe_eijdfiojdfg_oijdfg
Unlimited-length character fields in Postgres perform the same as limited-length fields, and the Postgres manual suggests not arbitrarily limiting these fields. Unfortunately, Django does not provide a way to access unlimited-length character fields except using TextField, which is rendered differently in forms and in the admin, and has different connotations. LongCharField is a way to avoid putting arbitrary max_length values where they aren't required. It will only work with databases that allow VARCHAR with no numeric parameters, such as Postgres. MySQL won't work.
Complex of tags and filters for easy replacement of text with alternative font faces. For browsers, who doesn`t support it by themselves. Templatetag code and documentation at [GitHub of django-headline](http://github.com/SkAZi/django-headline).
