9 ////////////////////////////////////////
11 modified querytable for univbris foam
12 ///////////////////////////////////////
14 A plugin for displaying a query as a list
16 More accurately, we consider a subject entity (say, a slice)
17 that can be linked to any number of related entities (say, resources, or users)
18 The 'query' argument will correspond to the subject, while
19 'query_all' will fetch the complete list of
20 possible candidates for the relationship.
22 Current implementation makes the following assumptions
23 * query will only retrieve for the related items a list of fields
24 that corresponds to the initial set of fields displayed in the table
25 * query_all on the contrary is expected to return the complete set of
26 available attributes that may be of interest, so that using a QueryEditor
27 one can easily extend this table without having to query the backend
28 * checkboxes is a boolean flag, set to true if a rightmost column
29 with checkboxes is desired
30 * optionally pass columns as the initial set of columns
31 if None then this is taken from the query's fields
32 * init_key is the name of a column that should appear in both queries
33 and used internally in the plugin for checkboxes initialization.
34 If not specified, metadata will be used to find out a primary key.
35 However in the case of nodes & slice for example, the default key
36 as returned by the metadata would be 'urn', but 'urn' could only
37 be used for this purpose if it gets displayed initially, which is
38 not necessarily a good idea.
39 This is why a slice view would use 'hrn' here instead.
40 * datatables_options are passed to dataTables as-is;
41 however please refrain from passing an 'aoColumns'
42 as we use 'aoColumnDefs' instead.
