Exploring Hidden View-Helper Methods in Rails

In Rails, there are several lesser-known view-helper methods that can significantly simplify your development process. Let’s delve into these hidden gems and understand how they can streamline your Rails application.

1. button_to

The button_to method generates a form containing a single button that submits to the specified URL.

Examples

<%= button_to "New", action: "new" %>

This will generate:

<form method="post" action="/controller/new" class="button_to">
  <input value="New" type="submit" />
</form>

For more information, check the API documentation.

2. link_to_unless_current

The link_to_unless_current method creates a link tag for the given name and URL unless the current request URI matches the link’s URL.

Example

<ul id="navbar">
  <li><%= link_to_unless_current("Home", { action: "index" }) %></li>
  <li><%= link_to_unless_current("About Us", { action: "about" }) %></li>
</ul>

3. link_to_unless

The link_to_unless method creates a link tag for the given name and URL unless a specified condition is true.

Example

<%=
  link_to_unless(@current_user.nil?, "Reply", { action: "reply" }) do |name|
    link_to(name, { controller: "accounts", action: "signup" })
  end
