body: <p>I am new to Ruby on Rails. I have a simple application which connects to twitter. The application has a search text box on the home page and a submit button.Also there is a model and the controller for the same. I want to search some keywords dynamically on twitter and then display them on the home page of our application. I have created a text box and submit button in the "index.html.erb" page. I don't know how to take the keyword and pass into the controller. Then i want to display the result of the search. Can anyone site an example for the same ? Kindly suggest errors /changes in the code. like-this ruby on rails</p>
