Separate Templates for each Locale

If the request processor finds a file named filename.locale.adp, where locale matches the user's locale, it will process that file instead of filename.adp. For example, for a user with locale tl_PH, the file index.tl_PH.adp, if found, will be used instead of index.adp. The locale-specific file should thus contain text in the language appropriate for that locale. The code in the page, however, should still be in English. Message keys are still processed.

Internationalize Date and Time queries

  1. Find datetime in .xql files. Use command line tools to find suspect SQL code:

    grep -r "to_char.*H" *
     grep -r "to_date.*H" *
     
  2. In SQL statements, replace the format string with the ANSI standard format, YYYY-MM-DD HH24:MI:SS and change the field name to *_ansi so that it cannot be confused with previous, improperly formatting fields. For example,

    to_char(timestamp,'MM/DD/YYYY HH:MI:SS') as foo_date_pretty

    becomes

    to_char(timestamp,'YYYY-MM-DD HH24:MI:SS') as foo_date_ansi
  3. In TCL files where the date fields are used, convert the datetime from local server timezone, which is how it's stored in the database, to the user's timezone for display. Do this with the localizing function lc_time_system_to_conn:

     set foo_date_ansi [lc_time_system_to_conn $foo_date_ansi]

    When a datetime will be written to the database, first convert it from the user's local time to the server's timezone with lc_time_conn_to_system.
