Rails: form_for and radio buttons

Question

I have the following in my form_for

<div class="multiple_students">
        <%= f.label :multiple_classes, "Do you teach multiple classes?" %>
        <%= f.radio_button :multiple_classes, 1, checked: @user.multiple_classes?, class: 'multiple_classes', data: { question: 'What is your average class size?' } %> <%= f.label :multiple_classes, "Yes", class: 'multiple_classes' %>
        <%= f.radio_button :multiple_classes, 0, checked: @user.multiple_classes?, class: 'multiple_classes', data: { question: 'How many kids do you teach?' } %> <%= f.label :multiple_classes, "No", class: 'multiple_classes' %>
    </div>
    <div class="number_of_students hide">
        <%= f.label :students %>
        <%= f.text_field :students, :class=>"student_count required digits" %>
    </div>

For some reason the "No" is ALWAYS checked even if the multiple_classes attribute on the user is selected a true in the database (multiple_classes is a boolean type in the database)

why do you creating two radio buttons? you can do it in a single ain't u? — Sri

@Vinay - well, the user can select whether they teach multiple classes or not by selecting a radio button — dennismonsewicz

I believe @Vinay is suggesting you could just use a single checkbox. — Chowlett

Ok if you want to use only the radio_buttons, check the following and let me know if thats worked.

<%= f.radio_button :multiple_classes, "1", checked: @user.multiple_classes?, class: 'multiple_classes', data: { question: 'What is your average class size?' } %> <%= f.label :multiple_classes, "Yes", class: 'multiple_classes' %>
<%= f.radio_button :multiple_classes, "0", checked: @user.multiple_classes?, class: 'multiple_classes', data: { question: 'How many kids do you teach?' } %> <%= f.label :multiple_classes, "No", class: 'multiple_classes' %>

put the 1 and 0 with quotes and try....

Its not an answer... its only an idea...

The problem with always checked "No" is in a typo.

If you revert @user.multiple_classes? for "No", checkbox will be unchecked if @user.multiple_classes? is true, so the next code chunk should work fine:

<%= f.radio_button :multiple_classes, 1, checked: @user.multiple_classes?, class: 'multiple_classes', data: { question: 'What is your average class size?' } %> <%= f.label :multiple_classes, "Yes", class: 'multiple_classes' %>
<%= f.radio_button :multiple_classes, 0, checked: [email protected]_classes?, class: 'multiple_classes', data: { question: 'How many kids do you teach?' } %> <%= f.label :multiple_classes, "No", class: 'multiple_classes' %>
