- Collection.add( name [, parentCollectionID] ) -- saves new collection in DB and returns new Collection object; defaults to root if parent not provided
Currently some exceptions in folderTreeView.js when notified on collection add
- Added back Item.isCollection() and Collection.isCollection(), as they seem to still be used
- Collection._load() now takes optional ids for loading new collections
Close buttons on the Metadata and Notes.
The Collections list no longer throws an exception when the header is clicked.
More minor interface improvements.
This behavior of JS has some implications for how interface code handles things like deletes. The following won't do what one might expect/desire (and my apologies if this is obvious or redundant, but I figure it's worth pointing out):
var item = Scholar.Items.get(1);
Scholar.debug(item);
Scholar.DB.query("DELETE FROM items WHERE itemID=1");
Scholar.Items.reloadAll();
Scholar.debug(item);
The last line will still display the old object, even though _items[1] has been deleted inside Scholar.Items. The following does work, however:
var item = Scholar.Items.get(1);
Scholar.debug(item);
Scholar.DB.query("DELETE FROM items WHERE itemID=1");
Scholar.Items.reloadAll();
var item = Scholar.Items.get(1);
Scholar.debug(item);
Now item is properly undefined. Moral of the story: object references need to be deleted manually after receiving delete notifications, for if external code still has references to deleted data objects, the data layer can't do much about it.
Revised the way the dateAdded and dateModified columns are displayed.
Views are now unregistered on window close.
A few functions in overlay.js were renamed.
Began better commenting of the interface code.
Although I do not yet have interface code for it, collections do not have any sort of setName(), save() functions.
Collections list now implements notify()
Made some fixes on itemTreeView to allow for notify() on multiple deletes
(shifts the row identifier up 1 for each previous delete, etc.)
One more thing -- this might not happen because the tree calls each Item.erase() or Collection.removeItem() individually.
Bug fix on notifier.js so that register*Tree() actually returns the hash. :-)
Unfortunately, unregister*Tree() does not seem to actually work, there is still an object at _observers['itemTree'][hash]
(temporary): When you select an item Scholar no longer loads a page into the browser.
The javascript bugs on those HTML pages were frustrating the debugger.
- Added Notifier triggers to Item.erase() (which only runs if not in a nested transaction) and Collections.erase()
- notify() in ItemTreeView updated with example of taking multiple ids, though it doesn't actually work (and notify() implementations may decide just to refresh the whole tree when ids.length>1 rather than dealing with changes individually)
- When deleting collections, use DB tables that actually exist
Scholar.Notifier framework to handle update notifications between data layer and interface
- Notifier.registerColumnTree(ref) and Notifier.registerItemTree(ref) pass back a unique hash that can be used to unregister the tree later with unregister*(hash) (and must be, lest we leak treeViews and probably entire browser windows if the browser window is closed without unregistering the treeView)
- Data layer calls Scholar.Notify.trigger(event, type, id) after various events (only two calls in the data layer at the moment--more coming later)
- Notify.trigger() calls notify(event, type, id) on all registered trees of the appropriate type -- the data layer usually knows what collection the action pertains to, but we decided that it's cleaner to just let the tree decide what it wants to do rather than add all that logic into the data layer)
(Note: Item collection adds appear to be buggy on the interface side, but removes seem to be working)
Overhauled data access layer to support new model:
- Changed Item.getParent to Item.getCollections() to get ids of parent collections
- Removed Item.setPosition() -- item positions are set internally when items are added to and deleted from collections, but the orderIndex is not currently used or manipulatable externally
- Item constructor/Items.getNewItemByType()/Items.add() no longer take folderID and orderIndex as parameters
- Split getTreeRows() into Scholar.getCollections(parent) and Scholar.getItems(parent), which return root collections or all library items, respectively, if no parent given
- All references to folders in object/method/property names changed to collections
- New methods Collection.addItem(itemID), Collection.hasItem(itemID), Collection.removeItem(itemID)
- Collection.erase() takes optional deleteItems parameter to delete items from DB -- otherwise just removes association and leaves item in library (does, however, delete all descendent collections from DB regardless)
* Note: This will break displaying of items until interface code is updated. *
Scholar.TreeView is now Scholar.FolderTreeView (SourcesTreeView later? depends)
Some changes to the way FolderTreeView works.
New Scholar.ItemGroup -- used by FolderTreeView and ItemTreeView.
the root folder is not currently displayed -- doesn't really matter because we are changing the way it all works.
(note: the Scholar.Items.getAll() function does not seem to be working correctly -- try clicking on the library)
Switching to scholar@chnm.gmu.edu -- SVN folks should rename the text file in their FF profile directories. (Used to be scholar@chnm, so you need to make the change even if you hadn't changed to the GUID yet.) Anyone who's tried the XPI yet will need to reinstall just once from the URL (http://chnm.gmu.edu/firefoxscholar/download/scholar-dev.xpi), as the old version won't find updates with its id.
* Renamed treeView.js to folderTreeView.js (more changes on this file forthcoming) -- this will soon be specifically for folders.
* Added itemTreeView.js, with new Scholar.ItemTreeView class -- specifically for items.
* The items list now supports 3 additional columns: rights, date added, and date modified.
* For now, selecting an item loads the "I'm Feeling Lucky" result of a Google search on the item title.
Added update.rdf for auto-update mechanism (which will get moved out of the extension root by the build system but should stay with a particular tree)
Assigned a new GUID to extension
*** Important: The extension GUID has changed, so you should rename the scholar@chnm text file in your Firefox profile exensions directory to our new GUID "{e007c81c-eb2a-4e1d-b381-d25a45cd11ed}" and restart Firefox ***
More details coming on Basecamp: http://chnm.grouphub.com/W161222
*** Important note: after checking out this code, be sure to delete the compreg.dat and xpti.dat files in your FF profile directory or else the extension will not load. They'll be regenerated when you start FF again, and you won't have to do it again unless we add interfaces or other components. Once I set up the XPI packaging system, this step won't be necessary. ***
- Localization properties are now loaded directly via nsIStringBundleService and available via Scholar.getString(name) -- removed stringbundle from XUL
- Updated status line in bottom right to reflect whether Scholar is loaded correctly or not (temporary, obviously)
