javascript - BookshelfJS: Is it possible to reformat data from `withPivot` -

i'm using bookshelf create simple restful api , return consistent camelcase format while using underscore_database_columns.

i using format , parse methods documentation exception of withpivot data.

all code simplified project please forgive syntax errors etc, may not exist in real code

i have 2 models, recipe , ingredient.

var recipe = basemodel.extend({   tablename: 'recipe',    defaults: { name: null },    ingredients: function () {     return       .belongstomany('ingredient')       .withpivot(['measurement', 'sort_order']);   } }));  var ingredient = basemodel.extend({   tablename: 'ingredients',    defaults: { name: null },    recipes: function () {     return       .belongstomany('recipe');   } })); 

i querying following:

model   .forge({     id: 1   })   .fetch({     withrelated: ['ingredients']   })   .then(function (model) {     return res.json(model.tojson());   })   .catch(function (err) {     return done(err);   }); 

which returns:

{   "id": 1,   "name": "yummy thing",   "ingredients": [     {       "id": 1,       "name": "food stuff",       "_pivot_ingredient_id": 1,       "_pivot_recipe_id": 1,       "_pivot_measurement": "loads",       "_pivot_sort_order": 1     }   ] } 

as can see _pivot data snake_case .withpivot(['measurement', 'sort_order']) pointing table column names rather attributes.

is there way reference , return pivot data camelcase?

i've overridden tojson works fine feels wrong given base models using camelcase default.

tojson: function () {   var data = basemodel.prototype.tojson.apply(this, arguments);   data.ingredients && (data.ingredients = data.ingredients.map(this.parse));   return data; } 

i'm open using through models couldn't work out how return through table data fetch. (i'm not set on the above json format long data there in form.)
