ruby - Create a rails controller which will update multiple tables in db -

i new rails. can create 1 controller take json info , update multiple table in db? contoller nuthing in view.

i doing following:- routes.rb:

post '/data' => 'data#submit'

app/controllers/data_controller.rb:

class datacontroller < applicationcontroller def submit info = json.parse request.body.read puts info end end

then sending post request,

restclient.post "localhost:3000/submit_result", data.to_json, {:content_type => :json}

but gving error

actioncontroller::routingerror (uninitialized constant datacontroller)

you need create route in config/routes.rb it.

if have action, definition like

resource :data, only: [] post :submit end

only: [] => makes default crud actions not beingness created.

then in controller can following:

class datacontroller < applicationcontroller def submit info = json.parse params[:some_key] puts info render nothing: true # avoid view rendering end end

your rest client should phone call this:

restclient.post "localhost:3000/data/submit", data.to_json, {:content_type => :json}

about if can update multiple tables controller: yes, possible.

suppose send info next format:

restclient.post "localhost:3000/data/submit", {user: {name: 'john'}, role: {name: 'admins'} }.to_json, {:content_type => :json}

then, in controller create user , role, based on received params:

class datacontroller < applicationcontroller def submit user.create params[:user] role.create params[:role] render nothing: true # avoid view rendering end end

anyway might complicate controller's code. best approach create new class receiving params , creatign stuff need.

class datacontroller < applicationcontroller def submit massdatacreator.create(params) render nothing: true # avoid view rendering end end

the benefit of controller code looks clearer, , can write unit tests new class creates info (it's easier test single class unit testing controller through integration tests)
