Ruby on Rails Form Helpers Helpers for form elements
Example
Checkboxes
<%= check_box_tag(:pet_dog) %>
<%= label_tag(:pet_dog, "I own a dog") %>
<%= check_box_tag(:pet_cat) %>
<%= label_tag(:pet_cat, "I own a cat") %>
This will generate the following html
<input id="pet_dog" name="pet_dog" type="checkbox" value="1" />
<label for="pet_dog">I own a dog</label>
<input id="pet_cat" name="pet_cat" type="checkbox" value="1" />
<label for="pet_cat">I own a cat</label>
Radio Buttons
<%= radio_button_tag(:age, "child") %>
<%= label_tag(:age_child, "I am younger than 18") %>
<%= radio_button_tag(:age, "adult") %>
<%= label_tag(:age_adult, "I'm over 18") %>
This generates the following HTML
<input id="age_child" name="age" type="radio" value="child" />
<label for="age_child">I am younger than 18</label>
<input id="age_adult" name="age" type="radio" value="adult" />
<label for="age_adult">I'm over 18</label>
Text Area
To create a larger text box, it is recommended to use the text_area_tag
<%= text_area_tag(:message, "This is a longer text field", size: "25x6") %>
This will create the following HTML
<textarea id="message" name="message" cols="25" rows="6">This is a longer text field</textarea>
Number Field
This will create an input<type="number"> element
<%= number_field :product, :rating %>
To specify a range of values, we can use the in: option
<%= number_field :product, :rating, in: 1..10 %>
Password Field
Sometimes you want the characters typed by the user to be masked. This will generate an <input type="password">
<%= password_field_tag(:password) %>
Email Field
This will create an <input type="email">
<%= email_field(:user, :email) %>
Telephone Field
This will create an <input type="tel">.
<%= telephone_field :user, :phone %>
