    text
    copied!<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>
