Null value in mysql database table

Rails
1

I want to save four fields(name,latitude,longitude,location) coming from
my android phone to mysql table through ruby. I did the follwing code in
my update file.

def update

  @trackdata_items=Trackdata.new(params[:trackdata_items])

  if @trackdata_items.save

  render :text => '{
      "success":true,
            "info":"ok",
            "data":{
            "tasks":[
              {"title":"Complete the app"}
            ]
         }
        }'


   else
        render :status => :unprocessable_entity,
       :json => {   :success => false,
                  :info => resource.errors,
                   :data => {} }
end

end

But my sql database is updating each time with NULL values. what to do ?

This looks more like a create action than an update action.

But my sql database is updating each time with NULL values. what to do ?

First look in development.log to see what parameters are being posted
and which action is called.

Most of the time unless you are some weird ass developer it will be
right there in the terminal by way of STDERR because you will
preferably start a non-daemonized testing server, otherwise it will be
in log/development.log relative to the root of your base Rails app.

In that case start by working right through a good tutorial such as
railstutorial.org (which is free to use online). That will show you
the basics of Rails. Do that before starting your own project, it
will save you a lot of time in the long run.

The log in in log/development.log though if you just want to see where
you are going wrong. But then do the tutorial.

Run: tail -f log/development.log from your project root directory
You should see the same log in the terminal where you run your server

Actually I am almost at the end of my project. If I got this I can
complete my project. Thats why I asked.
