  1. POLocalizing a text field containing a number in Ruby on Rails
    text
    copied!<p>I am currently working on a project to internationalize one of our ruby-on-rails web applications so that it can be used in other countries (France will be the first one in this case).</p> <p>A particular issue I haven't worked out yet is with the displaying of numeric fields. When displaying numbers for display purposes only, I do the following:</p> <pre><code>&lt;%= number_to_percentage(tax.rate, :precision =&gt; 2)%&gt; </code></pre> <p>In English, this shows <strong>17.50</strong>, but in French it shows <strong>17,50</strong> (with a comma in place of the decimal point) which is as expected. The problem comes in the Edit form, when I show a text field</p> <pre><code>&lt;%= f.text_field :rate, :size =&gt; 15 %&gt; </code></pre> <p>When this renders a text box on the screen, the text box always shows <strong>17.50</strong> with a full stop rather than a comma for French. I am not sure that is correct.</p> <p>When I tried doing the following:</p> <pre><code>&lt;%= f.text_field :rate, :size =&gt; 15, :value =&gt; number_with_precision(f.object.rate, :precision =&gt; 2) %&gt; </code></pre> <p>This did indeed show <strong>17,50</strong> in the text box for French, but when I click on the Update button to save the form, the Ruby validation kicks in and tells me that <strong>17,50</strong> is not a number (or rather it says "n'est pas un nombre"). I have to enter <strong>17.50</strong> to get it to save.</p> <p>To be honest, I am not entirely sure on the correct thing to do here. Should all countries enter numbers with full stops in text boxes, or is there a way to get Ruby-on-Rails to display commas, and validate them appropriately?</p>
