Usability improvements for course configuration screen.
lonconfigsettings.pm
- Wording change in breadcrumbs: "Display/Edit Settings" replaces "Course Settings".
- Changes in args passed to courseprefs::process_changes().
- Added call to courseprefs::store_changes to save to environment.db
- Added call to courseprefs::display_disallowed().
courseprefs.pm
- Moved code to generate array of names of all course configuration settings to &get_allitems() routine to facilitate reuse.
- Text descriptions of config settings moved to hash within entry for each category.
- Hash ref $disallowed passed as additional arg to process_changes() to accumulate requested changes that are not permitted.
- &process_changes() routine used to populate %changes hash with settings that have changed (and their new values).
- &check_clone() used to check requested cloners have valid username/domain.
- &store_changes() used to populate %storehash with change settings so they can be written to environment.db and also generates output to show what has been changed.
- Ability to create (new) custom course setting added tp print_other().
- Replace use of &Apache::lonnet::privileged() with retrieval of &Apache::lonnet::get_domain_roles() for dc roles.
- &get_lang_choices() routine added to retrieve hash of supported languages.
- &cloners_javascript() added to provide update_cloners() javascript function which will toggle radio buttons appropriately for any domain, any user from specified domain etc.
- &update_env() to append certain course config changes to current %env, and also update nohist_courseids.db
- &display_disallowed() to display information about requested setting changes which did not occur because they were disallowed.
- course environment settings are deleted from environment.db if they are changed to undef.
- Work in progess - logging (and logging interface) still needed.
