Hi, This is a brainstorming aimed at fixing: * http://jira.xwiki.org/browse/XWIKI-10384 * http://jira.xwiki.org/browse/XWIKI-12033 In addition I believe we need to support the following use cases: * UC1: (Simple) users should be able to see documents in the currently selected UI language and documents with no translations * UC2: (Advanced) users should be able to see all documents in the wiki (i.e. all translations + all docs with no translations) * UC3: It could be interesting to have an option to limit the translations to the list of configured languages of the wiki ATM the issues is that: * the “currentlanguage” query filter is not implemented properly and returns duplicates (the default language + the translation) * sorting can fail * there’s no way for an advanced users to see all translations in the AllDocs LT Also note that Marius (who’s discovered the problem) as commented at http://jira.xwiki.org/browse/XWIKI-9229 There are several solutions I can imagine Solution 1 ======== The idea is to implement a query filter that returns “a given language + the default language if there’s no translation”. It can be done, see http://jira.xwiki.org/browse/XWIKI-9229?focusedCommentId=90654&page=com… Pros: - Generic solution that would work wherever we use the query manager in the wiki Cons: - it’s “slow”. - It’s also not solving UC2 and UC3. Solution 2 ======== When the wiki is in multilingual mode, add a “Language” column in the LT and display all docs having translations in one of the configured languages of the wiki + all docs with no translations. The user will see duplicates but the “Language” column will indicate clearly that they are different translations. Pros: - This would fix UC3, partially UC2 and partially UC1. Cons: - Not a generic solution; only solves the issue for the AllDocs LT (and the other places where we want to do the same). Solution 3 ======== (initially proposed by Marius) Have a toggle with several states somewhere in the AllDocs UI (could be outside of the LT) to be able to choose different results: * Only docs in the current UI language * Only docs that don’t have translations * All docs * All docs in one of the configured languages of the wiki Note that from a wiki syntax POV, this could be a parameter in the {{document/}} live table. Pros: - This would fix UC2, UC3 and partially UC1. Cons: - Not a generic solution; only solves the issue for the AllDocs LT (and the other places where we want to do the same). Solution 4 ========= Modify the DB schema and add a column in the xwikidocs table to indicate if a doc has translations. This would mean updating it when a new translation is created and when a translation is removed. Pros: - Fast query - Generic solution that will work with any query using the query manager Cons: - Requires a DB update Conclusion ========= Solution 4 seems to be the only real generic solution. WDYT? Any other idea? Thanks -Vincent
