Ruby On Rails:recieve json, parse and save in database - ruby-on-rails

Question

I want post a json to rails controller and then save each of json to database by separate controller.
For this, I post this json to rails controller:
jsonList = {
"table": {column1:"column1",column2:"column2"},
"record": {name:"record 1"}
};
and recieve below json in rails controller:
Started POST "/api/calculate.json" for 127.0.0.1 at 2014-11-19 00:52:13 +0330
Processing by Api::V1::CalculateController#create as JSON
Parameters: {"table"=>{"column1"=>"column1", "column2"=>"column2"}, "record"=>{"name"=>"record 1"}, "calculate"=>{"table"=>{"column1"=>"column1", "column2"=>"column2"}, "record"=>{"name"=>"record 1"}}}
But I get below error in rails server log before I do anything:
Completed 500 Internal Server Error in 2ms
ActionView::MissingTemplate (Missing template api/v1/calculate/create, api/v1/base/create with {:locale=>[:en], :formats=>[:json], :variants=>[], :handlers=>[:erb, :builder, :raw, :ruby, :coffee, :jbuilder]}. Searched in:
* "/Users/mgh/Documents/Maliat/sama/app/views"
):

actionview (4.1.6) lib/action_view/renderer/template_renderer.rb:41:in `determine_template'
I search for this error, but don't find any usefull guide.
RailsController:
class Api::V1::CalculateController < Api::V1::BaseController
require 'json'
def create
....
end
end
I have another question. I want save each json to database by separate controller. For example I have a RecordController and use create action by below code:
def create
temp = Record.new(params[:record])
temp.save
end
and this type:
def create
temp = Record.create(params[:record])
end
but I get below error in server log:
ActiveModel::ForbiddenAttributesError (ActiveModel::ForbiddenAttributesError):
app/controllers/api/v1/calculate_controller.rb:6:in `create'
RecordController:
class Api::V1::RecordController < Api::V1::BaseController
require 'json'
def create
#data = Record.create(record_params)
#data.save
respond_with(#data)
end
private
def record_params
params.require(:record).permit(:name)
end
end
How can I fix this problems?

Answer 1

You need to review the use of strong parameters features in Rails. A similar question is also answered here: Active Model Forbidden attributes error

Answer 2

Why you wanna split JSON and send to two separate controllers instead of that create one controller method and parse your JSON and store into the database,
JSON format:
{
"table": {column1:"column1",column2:"column2"},
"record": {name:"record 1"}
};
Controller method:
def create_record_and_table
record = params[:record]
#record = Record.new(:name => record['name'])
#record.save
table = params[:table]
#table = Table.new(:column1 => table['column1'], :column2 => table['column2'])
#table.save
end
