Helpers Ruby On Rails

Learn how to use ruby on rails helpers with an example to simplify your code.

Helpers in Ruby On Rails

Ruby on Rails has a variety of helpful helpers that are built into the framework to assist developers with common tasks. These helpers provide a quick and easy way to perform common operations, like formatting text, creating forms, and generating URLs.

For instance, the link_to helper is used to create a link in a view. The link_to helper is used to generate an HTML anchor tag that links to another page. It looks like this:

<%= link_to "My Link", my_path %>

This will create a link with the text “My Link” and when clicked, it will take the user to the page specified by the my_path variable.

Another common helper is the form_for helper. This helper is used to generate HTML forms. It looks like this:

<%= form_for @user do |f| %>
  <%= f.label :name %>
  <%= f.text_field :name %>
<% end %>

This code will generate a form with a text field for the user's name. The form_for helper can also be used to create forms with other types of inputs, like checkboxes, radio buttons, and select boxes.

These are just two examples of the many helpful helpers that are built into the Ruby on Rails framework. There are many more that can be used to speed up development and make programming more efficient.
