    <p>I have created a Ruby on Rails application and <strong>integrated twitter</strong>. But i am facing some issues while running it. I have an index page with a <strong>search box</strong> and a <strong>submit button</strong>. The application tries to search the keywords entered on twitter and then display it dynamically on the application page(the create.html.page for dynamically displaying tweets). So there is a "tweet controller" and two html.erb files. "Index.html.erb" , "create.html.erb" . And a model. The index method in controller is used to display feeds using a <strong>specific keyword</strong> (You can say like a <strong>static</strong> way). The create method is used to <strong>dynamically display the tweets</strong> based on the keyword entered in the index.html.erb. I wanted to avoid using form_for or form_tag so created a form using html form tag.</p> <p>When i try to execute the url "http:localhost:3000/tweets/create" it displays an error that <strong>symbol as array index</strong> When i try to execute the url "http:localhost:3000/tweets/index" , the page is not rendered. Kindly help. I m posting the controller, views below.</p> <p>Thanks, bhargav</p> <p><strong>"Index.html.erb"</strong></p> <pre><code>&lt;h1&gt;Tweets about New Year Resolution&lt;/h1&gt; &lt;form action="/create" method="post"&gt; &lt;label for="keyword"&gt;keyword&lt;/label&gt; &lt;input id="keyword" name="Enter keyword" size="30" type="text" /&gt; &lt;input type="submit" value="search" /&gt; &lt;/form&gt; &lt;% if (@tweets != nil) then %&gt; print "The tweets are " @tweets &lt;% else %&gt; print "No tweets for the keyword" &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;`enter code here` &lt;% end %&gt; &lt;/ul&gt; &lt;/div&gt; </code></pre> <p><strong>"create.html.erb"</strong></p> <pre><code>&lt;h1&gt;Keywords displayed&lt;/h1&gt; &lt;p&gt; A page to display tweets &lt;/p&gt; </code></pre> <p><strong>"tweets_controller.rb"</strong></p> <pre><code>class TweetsController &lt; ApplicationController def index #Get the tweets (records) from the model Ordered by 'twitter_created_at' descending if Tweet.count &gt; 0 Tweet.delete_all end Tweet.get_latest_new_year_resolution_tweets("India") @tweets = Tweet.order("twitter_created_at desc") end def create @tweets = (params [:tweet][:search]) Tweet.get_latest_new_year_resolution_tweets(@tweets) end end </code></pre> <p>The <strong>model</strong> *<em>tweet.rb</em>* contains the method get_latest_new_year_resolution_tweets .

    1. COlooks like the method `get_latest_new_year_resolution_tweets` expects an array but is getting a hash, as the index in a hash is a symbol it throws the error, need to see the method def to be precise though.

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.
