Package: django-i18n-helper
Provides a simple way to visualize translated strings in Django templates
by wrapping translated content with custom HTML and CSS. Therefore and
most important, helps you to visualize untraslated strings too.How does it workDjango i18n helper is a common Django app that overriddes Django core functions
on load to provide the desired behavior.The application will automatically detect when tests are being run and won’t
override any methods in such a case to preserve tests integrity.InstallationGet itpip install django-i18n-helperAfter, all you need to do is add “i18n_helper” to your installed apps and
activate the internationalization debug. In your settings.py, make sure to have:INSTALLED_APPS = (…,
‘i18n_helper’
)andI18N_HELPER_DEBUG  = Truedjango-i18n-helper provides a default behavior that consists in wrapping the
translated content with an HTML div with the following properties:<div class=’i18n-helper’ style=’display: inline; background-color: #FAF9A7;’>Translated text</div>This provides a soft highlight for translated strings, but this behavior can be
modified within settings.py.CustomizationSome configuration variables are provided in order to customize how you want the translated strings to be wrapped.#### I18N_HELPER_HTMLDefines a whole HTML block for wrapping the translations. This string will be
formatted (http://docs.python.org/library/stdtypes.html#str.format) with the
translated text. Thus every occurrence of “{0}” will be replaced with the
translation.I18N_HELPER_HTML = “<span class=’highlight’>{0}</span>”IfI18N_HELPER_HTMLis not set, the code used will be<div class=’i18n-helper’ style=’display: inline; background-color: #FAF9A7;’>{0}</div>#### I18N_HELPER_CLASSDefines the class to use for the HTML div ifI18N_HELPER_HTMLis not used. Defaults to “i18n-helper”.I18N_HELPER_CLASS = “my-custom-class”#### I18N_HELPER_STYLEDefines the inline CSS for the HTML div if noI18N_HELPER_HTMLorI18N_HELPER_CLASShave been set (case in which it’s assumed that the css
for the class provides the desired style). Defaults to “display: inline; background-color: #FAF9A7;”.I18N_HELPER_CLASS = “font-weight: bold; background-color: yellow;”ScreenshotsGraphical examples are sometimes the better way to understand how does something works or looks like. So here go two examples of how completely translated templates would look like, and two of how partially translated templates would.Fully translated templates<img src=’http://pictat.com/i/2012/8/27/16220screenshot.png’/><img src=’http://pictat.com/i/2012/8/22/11913traslated2.png’/>Partially translated templates. Note that it’s also possible to see from the admin site which model fields haven’t set the _verbose_name_ attribute to translate the field name.<img src=’http://pictat.com/i/2012/8/22/23861untraslate.png’/><img src=’http://pictat.com/i/2012/8/22/21074untraslate.png’/>Disclaimer notesThe application shouldonlybe used when “debugging” code translations, since it overrides the default Django HTML scaping mechanism and thus outputs unescaped (possibly undesired) code.
Besides, there are some warnings you should be aware of:You will see weird HTML within you buttons or inputs if you have things like &lt;input type=”text” value=”{% trans “Search” %}” …&gt; Then the wrapping HTML of your translations will be shown _within_ the inputs or buttons. This will happen for sure in the admin site.SetI18N_HELPER_DEBUGto False before syncing your database, otherwise you might see errors like “value too long for type character varying(50)”.SetI18N_HELPER_DEBUGto False before running your migrations, otherwise you might see errors like “value too long for type character varying(50)”.From version0.1.1this helper will only be enabled when running therunservercommand, so you shouldn’t need to worry about turning it off for doing syncdb, migrations, or anything.Some capitalization might be lostTested withDjango 1.3 / 1.4Python 2.6.1 / 2.7.2ContactAuthor: Santiago Gabriel RomeroContact:sromero@machinalis.com
