-- Add support for category url slugs that are not based on the displayed category name
|
||||
-- And let Japan have Japanese category names, but English category urls.
|
||||
|
||||
-- 1. Add category_texts.display_name, default null
|
||||
ALTER TABLE category_texts ADD COLUMN IF NOT EXISTS display_name TEXT;
|
||||
COMMENT ON COLUMN category_texts.display_name IS 'Optional display name for the category. If null, the name column will be used.
|
||||
Intended use is for non western languages with characters that our getsafexmlpath() function is not able to create websafe slugs from';
|
||||
COMMENT ON COLUMN category_texts.name IS 'The url slug is created from this column';
|
||||
|
||||
-- 2. Populate display_name for Japanese. (which already has English in name, and Japanese in wallpaper_name)
|
||||
UPDATE category_texts SET display_name = wallpaper_name where locale_id = (select id from locales where value = 'ja_JP');
|
||||
