    <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> <p><strong>The contents of the index.html.erb</strong> </p> <pre><code>&lt;h1&gt;Tweets about New Year Resolution&lt;/h1&gt; &lt;tr&gt;&lt;td&gt;Enter keyword &lt;input type = "text" name = "keyword"&gt;&lt;/td&gt;&lt;/tr&gt; &lt;tr&gt;&lt;td&gt;&lt;input type = "submit" value = "SEARCH"&gt;&lt;/td&gt;&lt;/tr&gt; &lt;%= form_tag(tweets/index, :method =&gt; "get") do %&gt; &lt;%= label_tag(:q, "Enter keyword :") %&gt; &lt;%= text_field_tag(:q) %&gt; &lt;%= submit_tag("SEARCH") %&gt; &lt;% end %&gt; &lt;div id="container"&gt; &lt;ul&gt; &lt;% @tweets.each do |tweet| %&gt; &lt;li class="&lt;%=cycle('odd', '')%&gt;"&gt; &lt;%= link_to tweet.from_user, "http://twitter.com/#{tweet.from_user}", :class =&gt; "username", :target =&gt; "_blank" %&gt; &lt;div class="tweet_text_area"&gt; &lt;div class="tweet_text"&gt; &lt;%=raw display_content_with_links(tweet.text) %&gt; &lt;/div&gt; &lt;div class="tweet_created_at"&gt; &lt;%= time_ago_in_words tweet.twitter_created_at %&gt; ago &lt;/div&gt; &lt;/div&gt; &lt;/li&gt; &lt;% end %&gt; &lt;/ul&gt; &lt;/div&gt; </code></pre> <p><strong>The contents of the controller tweets.rb</strong></p> <pre><code>class TweetsController &lt; ApplicationController def index #Get the tweets (records) from the model Ordered by 'twitter_created_at' descending searchValue = params[:keyword] if Tweet.count &gt; 0 Tweet.delete_all end Tweet.get_latest_new_year_resolution_tweets("iphone") @tweets = Tweet.order("twitter_created_at desc") end end </code></pre>

    1. COI think you should change `searchValue = params[:keyword]` to `searchValue = params[ :q ]` to grab the input and remove `td/tr` part

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
