Rails supports a common feature of HTML that makes forms feel much more professional: labels. When labels are explicitly connected to the fields, clicking on the label shifts focus to the field. It gives users a bigger target to hit and simplifies accessibility as well.
Labels are easy. To make the headline “Name” associate with the field right below it, the scaffolding code uses:
<p> <%= f.label :name %><br /> <%= f.text_field :name %> </p>
The generated HTML contains a bit of extra information the browser uses to make the association:
</label></b><br /> <input id="person_name" name="person[name]" size="30" type="text" /> </p>
If you click on the word “Name,” focus will shift to the field for entering a name just below it.
If you want the label to say something other than the name of the field, just add a string as the second argument, as in:
<%= f.label :name, 'Your name' %>
This will generate:
<b><label for="person_name">Your name</label></b><br />
label method is a nice feature, but at the same
time it seems as if there’s a good deal of repetition going on in this code.
