For an integer, the argument is cast to a string before creating a list. If value is the string "Joel" , the output would be the list ['J', 'o', 'e', 'l']. If value is , the output will be the list ['1', '2', '3']. Returns a plural suffix if the value is not 1 , '1' , or an object of length 1.
By default, this suffix is 's'. For words that require a suffix other than 's' , you can provide an alternate suffix as a parameter to the filter. Use blocktranslate to pluralize translated strings. A wrapper around pprint. If value is the list ['a', 'b', 'c', 'd'] , the output could be "b".
If value is Django , the output will be " Django". Marks a string as not requiring further HTML escaping prior to output. When autoescaping is off, this filter has no effect.
If you are chaining filters, a filter applied after safe can make the contents unsafe again. For example, the following code prints the variable as is, unescaped:. Applies the safe filter to each element of a sequence. Useful in conjunction with other filters that operate on sequences, such as join. Converts spaces to hyphens. Converts to lowercase. Also strips leading and trailing whitespace. If value is "Joel is a slug" , the output will be "joel-is-a-slug".
Formats the variable according to the argument, a string formatting specifier. If value is 10 , the output will be 1. If you are looking for something more robust, you can use the bleach Python library, notably its clean method. Note that the predefined format is locale-dependent.
If value is equivalent to datetime. The time filter will only accept parameters in the format string that relate to the time of day, not the date.
If you need to format a date value, use the date filter instead or along with time if you need to render a full datetime value. There is one exception the above rule: When passed a datetime value with attached timezone information a time-zone-aware datetime instance the time filter will accept the timezone-related format specifiers 'e' , 'O' , 'T' and 'Z'. Takes an optional argument that is a variable containing the date to use as the comparison point without the argument, the comparison point is now.
Similar to timesince , except that it measures the time from now until the given date or datetime. Takes an optional argument that is a variable containing the date to use as the comparison point instead of now. Converts a string into titlecase by making words start with an uppercase character and the remaining characters lowercase. Truncates a string if it is longer than the specified number of characters. If value is "Joel is a slug" , the output will be "Joel i…".
Similar to truncatechars , except that it is aware of HTML tags. Any tags that are opened in the string and not closed before the truncation point are closed immediately after the truncation.
If value is "Joel is a slug" , the output will be "Joel is …". Similar to truncatewords , except that it is aware of HTML tags. Any tags that are opened in the string and not closed before the truncation point, are closed immediately after the truncation. This is less efficient than truncatewords , so should only be used when it is being passed HTML text. The list is assumed to be in the proper format. An empty string can be provided when all characters should be escaped. It also supports domain-only links ending in one of the original top level domains.
For example, djangoproject. Links can have trailing punctuation periods, commas, close-parens and leading punctuation opening parens , and urlize will still do the right thing. If value is "Check out www.
In addition to web links, urlize also converts email addresses into mailto: links. If value is "Send questions to foo example. The urlize filter also takes an optional parameter autoescape. The default value for autoescape is True. Apply this filter only to plain text. Converts URLs and email addresses into clickable links just like urlize , but truncates URLs longer than the given character limit.
As with urlize , this filter should only be applied to plain text. If value is "Joel is a slug" , the output will be 4. If value is Joel is a slug , the output would be:. Django provides template tags and filters to control each aspect of internationalization in templates. They allow for granular control of translations, formatting, and time zone conversions. This library allows specifying translatable text in templates.
See Internationalization: in template code. This library provides control over the localization of values in templates. See Controlling localization in templates. This library provides control over time zone conversions in templates. See Time zone aware output in templates. See django. If the django. It is also able to consume standard context variables, e. See Jinja2 for information on using the static tag with Jinja2. Offline Django 4. Django is a registered trademark of the Django Software Foundation.
Django The web framework for perfectionists with deadlines. Documentation Search: Search. Getting Help el es fr id it ja ko pl pt-br zh-hans Language: en 1. If the variable evaluates to a string, Django will use that string as the name of the parent template. If the variable evaluates to a Template object, Django will use that object as the parent template. Note The escape and safe filters are not acceptable arguments.
Tests if two values are the same object. This is useful for providing sample data in templates. This includes tab characters and newlines. Warning Strings that can be coerced to integers will be summed , not concatenated, as in the first example above. Useful for escaping strings in CSV, for example. Note These format characters are not used in Django outside of templates. Changed in Django 2.
For example: value Template Output For example, when the active locale is en English : value Template Output For example, when the active locale is pl Polish : value Template Output Changed in Django 3. Changed in Django 4. This works for both strings and lists. This will happily convert any string.
Note Use blocktranslate to pluralize translated strings. Note If you are chaining filters, a filter applied after safe can make the contents unsafe again. Joel is a slug. Notice how, in the question you just asked, most of the places where you entered two spaces, only one is showing up? In particular, user agents should collapse input white space sequences when producing output inter-word space.
Lott suggested, you can verify that my guess is correct by adding debug logging, or using the Firebug plugin for Firefox or something similar, to see exactly what's getting sent to the browser. Then you'll know for sure on which end the problem lies. Read more in django documentation.
I simple used '' around label option to get the complete text with space. Lets say you want to use an id for each html tag to be used as a permalink to reference while you generate this dynamically then for example your solution would be:.
Slugify removes all leading spaces, you'll need to rewrite this as a custom template tag to get the behaviour you're after. The original filter code looks like this.
You could change it like so:. You still might have problems as mentioned before with how html treats extra whitespace, you'd have to write another, deslugify filter. This tag keeps spaces and newlines. I copied Django's own tag linebreaksbr and then added a line to replace the spaces with nbsp. It does not replace single spaces so text source is still readable. I wrote this because I couldn't get the spacify tag other answer to work with linebreaksbr. If this is not what you want, just use " " instead.
