The following information is automatically extracted from the JS code files. Methods and variables that begin with the double underscore ("__") are considered to be part of the private API of the library.
lookupItem : function(tabname, itemid)
Find the item with the given ID for the given table and return it.
Error if the tablename does not exist, or if the item ID is not an integer
Return null if the itemid does not exist
getItemList : function(tabname)
Get the full list of records associated with given table.
This is one of the most fundamental operations of the framework.
Error if the table name is not loaded on the current page.
If you are uncertain if the table will be present, use haveTable(...) to check
buildItem : function(tabname, record)
Create a new record for the given table.
The record argument is a hash with keys corresponding to the column names of the table.
It is optional to provide the "id" column, if you do not provide it, the framework
will allocate a new id and assign it to the record.
Other than the id column, all columns must be explicitly provided.
IMPORTANT: this method creates the record but does not sync it to the server.
To sync, call syncItem on the returned JS representation of the record.
haveItem : function(tabname, itemid)
Check if the given table has an item with the given ID.
This is logically equivalent to calling getItemList
and checking each record to see if it has the ID,
but is faster because it uses the index on the table.
haveTable : function(tabname)
Return true if the table is in the data for the page.
getTableOwner : function(tabname)
Return the owner of the given table
haveWriteAccess : function(tabname)
True if the current user has write access to the given table
Widgets that serve multiple users, some of whom have write access and some of whom do not,
should check this function before displaying UI options that will perform write actions.
The backend will disallow such writes anyway, but it will be a less pleasing user experience
getFieldList : function(tabname)
Return the list of fields/columns in the given Table
These correspond exactly to the columns in the underlying SQLite table
This is basically equivalent to calling Object.keys(..) on one of the items,
but this works even if you don't have an instance of the item
getWidgetTableList : function()
Get all the tables that have been registered on this page.
newBasicId : function(tabname)
Creates a new ID for the given table name.
In general, users should not need to call this method; it is called automatically
when the "id" column is not explicitly supplied in the buildItem(...) data.
The ID is allocated by generating a random integer in the the useable range
and checking to make sure it is not already in use in the table.
The useable range is -2147483648 to 2147483647, with an exception for -1000 to 0
newIncrementalId : function(tabname)
Creates a new ID for the given table name.
The new ID is 1 greater than the previous max ID currently in the table
This approach to ID allocation is not recommended because it can cause problems in multi-user settings
serverSideNewDbId : function(tabname, callback)
Queries the server to obtain a new unused database ID for the given table
In other words, this is a server-side version of newBasicId(...)
It is generally better to use the client-side version. This method is intended to be used
in cases where you do not have all the records for the given table loaded in the client
For example, if you use the no_data=true option to load the table manager without loading any records
