Nested Attributes Unpermitted wit Embedded Mongoid Document via AJAX

Question

I am trying to submit a document and an embedded document via Ajax call but keep receiving an "Unpermitted parameter" exception. This is my model:

class UserForecast
...
  embeds_many :time_entries
  accepts_nested_attributes_for :time_entries
...
end

My strong parameters:

def user_forecast_params
  params.require(:user_forecast).permit(:published, :user_id, :forecast_id, :project_role_id, time_entries_attributes: [:entry_date, :hours])
end

The ajax call:

$.ajax({
    url : '/user_forecasts.json' ,
    data : { user_forecast: { user_id: timeEntry.data('user_id'), forecast_id: timeEntry.data('forecast_id'), project_role_id: timeEntry.data('project_role_id'), time_entries: { entry_date: timeEntry.data('date'), hours: timeEntry.value } }},
    type : 'post',
...

I cannot see anything that I am missing but yet I receive this in my logs:

Unpermitted parameter: time_entries

I am using: Ruby 2.3.0 Rails: 4.2.6 Mongoid: 5.1.5

Thank you all!

Ok, I figured this out.

first: Obviously, the JSON parameter name needs to be time_entries_attributes: and not time_entries.

$.ajax({
    url : '/user_forecasts.json' ,
    data : { user_forecast: { user_id: timeEntry.data('user_id'), forecast_id: timeEntry.data('forecast_id'), project_role_id: timeEntry.data('project_role_id'), time_entries_attributes: [{ entry_date: timeEntry.data('date'), hours: timeEntry.value }] }},
    type : 'post',

once I crossed that bridge, I ran into an *NoMethodError (undefined method `with_indifferent_access' for "2016-11-25":String): * error which is due to the fact that the time entry value needs to be an array:

[{ entry_date: timeEntry.data('date'), hours: timeEntry.value }]

This works!
