They only have to change something in context during rendering of templates. (Built-in {% with %} tag, for e.g.).You can make it output time like so:SO now you can use, to make creating tags like this simpler:Django 1.3 appeared to have functions pgettext() and ngettext() to indicate context for translatable strings. It solved problem of short text phrases partially. It suited phrases that can have different translation depending on context. Now you can transfer it in template directly:You can now sharewith special tag:Most profit will get those one's that for e.g. use CDN on S3, or another not "standart" way.is equivalent toin other cases.You also get newthat can add md5-hash to filenames from static, to make cash for css, js, images and so on definitely invalid.Incredible but true. After 4,5 years of Django dev you receivedin default filers list. It can trim string to provided amount of characters and change the end of it into three dots...
