    <p>I need to generate a url based on two drop-down inputs, from currency and two currency such that when a user clicks submit button, the url generated should look like <code>http://localhost:3000/currencies/usd-eur</code> when form currency is usd and to_currency is eur for example. </p> <p>Here's my views(index.html.erb) </p> <pre><code> &lt;%= semantic_form_for :calculator, :url =&gt; {:controller =&gt; "conversions", :action =&gt; "calculate" } do |f| %&gt; &lt;p&gt;&lt;%= f.label :amount %&gt; &lt;%= f.text_field :amount %&gt;&lt;/p&gt; &lt;p&gt;&lt;%= f.label :from_currency %&gt; &lt;%= select :calculator, :from_currency, Choices['from_currency'] %&gt;&lt;/p&gt; &lt;/p&gt;&lt;%= f.label :to_currency %&gt; &lt;%= select :calculator, :to_currency, Choices['to_currency'] %&gt;&lt;/p&gt; &lt;p&gt;&lt;%= f.submit "Calculate" %&gt;&lt;/p&gt; &lt;%= end %&gt; </code></pre> <p>routes.rb</p> <pre><code>match 'currencies', to: 'conversions#index', via: :get match 'currencies/convert', to: 'conversions#calculate', as: :calculate, via: :post </code></pre> <p>controller(conversions_controller.rb)</p> <pre><code>def index end def calculate @amount = params[:calculator][:amount] @from_cur = params[:calculator][:from_currency] @to_cur = params[:calculator][:to_currency] @result = ConversionsHelper.calculate(@from_cur, @to_cur, @amount) end </code></pre> <p>I don't have any models for that matter since I get my data from google API hence I could be going outside the boundaries of RESFFUL conventions. A detailed answer would be appreciated. Thanks. </p>

    1. COI have never tried dynamic routing like this but have you looked at `map.connect`?

    3. COconversions is not a model Swards. I'm using google API as my source and parse the values directly without storing them a db. As for engineersmnky, I haven't tried that method.

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.
