There is a python package named python-slugify, which does a pretty good job of slugifying: pip install python-slugify Works like this: from slugify import slugify txt = “This is a test —” r = slugify(txt) self.assertEquals(r, “this-is-a-test”) txt = “This — is a ## test —” r = slugify(txt) self.assertEquals(r, “this-is-a-test”) txt=”C\”est déjà l\’été.’ r … Read more
There is a python package called unidecode that I’ve adopted for the askbot Q&A forum, it works well for the latin-based alphabets and even looks reasonable for greek: >>> import unidecode >>> from unidecode import unidecode >>> unidecode(u’διακριτικός’) ‘diakritikos’ It does something weird with asian languages: >>> unidecode(u’影師嗎’) ‘Ying Shi Ma ‘ >>> Does this … Read more
There are two steps to solve this problem. First, create a new route or change the default route to accept an additional parameter: routes.MapRoute( “Default”, // Route name “{controller}/{action}/{id}/{ignoreThisBit}”, new { controller = “Home”, action = “Index”, id = “”, ignoreThisBit = “”} // Parameter defaults ) Now you can type whatever you want to … Read more
I like the php-slugs code at google code solution. But if you want a simpler one that works with UTF-8: function format_uri( $string, $separator=”-” ) { $accents_regex = ‘~&([a-z]{1,2})(?:acute|cedil|circ|grave|lig|orn|ring|slash|th|tilde|uml);~i’; $special_cases = array( ‘&’ => ‘and’, “‘” => ”); $string = mb_strtolower( trim( $string ), ‘UTF-8’ ); $string = str_replace( array_keys($special_cases), array_values( $special_cases), $string ); $string … Read more

The term ‘slug’ comes from the world of newspaper production. It’s an informal name given to a story during the production process. As the story winds its path from the beat reporter (assuming these even exist any more?) through to editor through to the “printing presses”, this is the name it is referenced by, e.g., … Read more
You will need to use the slugify function. >>> from django.template.defaultfilters import slugify >>> slugify(“b b b b”) u’b-b-b-b’ >>> You can call slugify automatically by overriding the save method: class Test(models.Model): q = models.CharField(max_length=30) s = models.SlugField() def save(self, *args, **kwargs): self.s = slugify(self.q) super(Test, self).save(*args, **kwargs) Be aware that the above will cause … Read more
