Django Rest Framework - Default OrderingFilter

[robert-malai]

The way the query params are build for sorting purposes doesn't play nice with the default filtering solution from Django Rest Framework.

Backbone Paginator is using two parameters to describe the filtering, where DRF is using only one, in which he's expecting a list of fields in the form ordering='column' or ordering='-column' for ascending, respectively descending sorting.

Would it be possible to move the params building code out in an overridable function ? at the moment, it resides in the fetch function, forcing me to override the whole function.

Kind of a patch solution:

state: {
    pageSize: 25
},

queryParams: {
    totalRecords: null,
    totalPages: null,
    pageSize: 'page_size',
    // this is special for DRF OrderingFilter
    ordering: function () {
        var sortKey = this.state.sortKey, order = this.state.order;
        if (sortKey && order !== 0) {
            return (order === 1 ? '-' : '') + sortKey;
        }
        return null;
    }
},

With this, I still send the sortKey and order params, I don't know how to block them.

Something like this?

            state: {
                pageSize: 25,
                firstPage: 1,
                currentPage: 1,
                sortKey: "created_at",
                order: -1
            },

            queryParams: {
                currentPage: "page",
                pageSize: "page_size",
                totalRecords: "count",
                order: null,
                sortKey: "ordering",
                ordering: function () {
                    var sortKey = this.state.sortKey, order = this.state.order;
                    if (sortKey && order !== 0) {
                        return (order === 1 ? '-' : '') + sortKey;
                    }
                    return null;
                }
            }
