Rails: how do I set ID or Name attribute in text_field_tag?

Question

<%= text_field_tag :barcode, params[:barcode] %>

generates

<input id="barcode" name="barcode" type="text"></input>

but I need

<input type="text" name="barcode" id="autocomplete"></input>

But in the documentation I did not find a way how to change the ID attribute.

I need to use a text_field_tag because it fills the textbox with params if submit fails.

Answer 1

try this

<%= text_field_tag :barcode, params[:barcode], id: 'autocomplete' %>

Answer 2

You can also try this...

<%= text_field_tag :barcode, params[:barcode], :id => 'autocomplete' %>
