Question

My View:

<div class="field">

  <%= label :isbn_exist, 'ISBN' %>
  <%= text_field :isbn_exist,'ISBN' %>
</div>

<%= link_to 'Add new book', new_book_path(:isbn_exist => @isbn_exist), :class => "btn btn-warning"%>

This “:isbn_exist” variable is not sent to the controller. why? If i put a number instead of @isbn_exist this value is sent. I think the text_field is not saving the value on the :isbn_exist variable…

Answer 1

You have a text_field and a link. What you really want is a form (including this text_field) and a submit button.

Things like this are covered in every rails tutorial you can find.
