Create a Django project, I use the Django 1.8.2, create a project, set the Chinese display support definition in settings.py

Language_code = ' en-US ' #改为zh-hans
error if changed to ZH-CN

Error notification

Django Ioerror:no translation files found for default language ZH-CN

The corresponding localization file for ZH-CN is not found. In general, the ZH-CN encoding corresponding to the localization folder for ZH_CN, I went to the Django installation directory to find ZH_CN, the results did not find, in the Django installation directory contrib subdirectory under the list of subdirectories in the locale folder, there is no ZH_CN, And there are zh_hans. The Zh_hans directory can be copied all a copy and named ZH_CN, you can solve this problem, the Admin interface displays the Chinese language.

What does use_i18n and use_l10n in settings.py mean when Web services are set up and can receive access from users from different countries around the world. This requires developers to tweak the software so that it can be used in different languages, namely internationalization and localization. There are 18 letters between internationalized –internationalization,i and N, abbreviated as i18n. Localized –localization, with 10 letters between L and N, referred to as l10n. Internationalization means that Web products have the potential to work anywhere, for program developers, and localization is the process of directing an international program to actually translate for use in a particular region, for translators.
