Question

if @challenge.name == 'foo'
  @challenge.category = 'habit'
  @challenge.days_challenged = 21
  @challenge.why = 'bar'
else

:days_challenged＆amp;在:why的_form中正确设置了foo，但没有: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

我假设您有目的地自定义编码单选按钮。选定的单选按钮应具有＆＃34;已检查＆＃34;，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' %>

默认对象属性不是默认的HTML
