:days_challenged & :why正确的_form为foo被设置但不:category。

<div class="challenge-category"> 
    <input class="date-format-switcher" type="radio" value="goal" name="challenge[category]" id="challenge_category_goal"> 
    <label for="challenge_category_goal">Goal</label> 

    <input class="date-format-switcher" type="radio" value="habit" name="challenge[category]" id="challenge_category_habit"> 
    <label for="challenge_category_habit">Habit</label> 
    </div> 
    <%= f.number_field :days_challenged, class: 'day-challenge' %> 
    <%= f.text_area :why %> 

Answer 1

我假设你有目的地为你的单选按钮定制编码。所选择的单选按钮应具备的属性“选中”，即

<input class="date-format-switcher" type="radio" value="habit" 
    name="challenge[category]" id="challenge_category_habit" checked /> 

动态设置：

<%= f.radio_button :category, 'goal', class: 'date-format-switcher' %> 
<%= f.radio_button :category, 'habit', class: 'date-format-switcher' %>
