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

I am using Bookhelf to create a fairly simple RESTful API and would like to return a consistent camelCase format when using underscore_database_columns.

I am using format

and parse

from the documentation to do this successfully, except for the data withPivot

.

All code is simplified from my project, so please ask for any syntax errors etc., they may not exist in my real code

I have two models: Recipe

and Ingredient

.

var Recipe = BaseModel.extend({
  tableName: 'recipe',

  defaults: { name: null },

  ingredients: function () {
    return this
      .belongsToMany('Ingredient')
      .withPivot(['measurement', 'sort_order']);
  }
}));

var Ingredient = BaseModel.extend({
  tableName: 'ingredients',

  defaults: { name: null },

  recipes: function () {
    return this
      .belongsToMany('Recipe');
  }
}));

      

        
        
        
      

    

I am asking for the 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 you can see, the data _pivot

is snake_case as is .withPivot(['measurement', 'sort_order'])

as it points to the table column names, not the attributes.

Is there a way to easily reference and return camelCase pivot data?

I've overridden toJSON

, which works great, but doesn't feel right, given that base models use camelCase by default.

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

      

        
        
        
      

    

I am open to using models through

, but I have not been able to work how to return table data through

using a selection. (I am not set to the above JSON format as long as all data is in some form or another.)
