繭寶石不顯示形式 - 軌道4

Question

我不確定爲什麼我的繭嵌套表格沒有出現任何幫助，將不勝感激

• 的<button><%= link_to_add_association 'add a required skill', f, :requiredskills %></button>作品非常清楚的顯示形式
• ，但我不清楚這是爲什麼不渲染的形式<%= render 'requiredskill_fields', :f => duty %>

• 我想要做的就是有一個表格已經顯示nd當用戶點擊add a required skill時會顯示另一個表單。 目前，當用戶點擊add a required skill，顯示 另一種形式 - 主要問題是有一個表格最初顯示 。我假定這<%= render 'requiredskill_fields', :f => duty %>是假設到位形式，但我不確定它爲什麼不工作

Answer 1

def edit 
    @requiredskills = @user.requiredskills.present? ? @user.requiredskills : @user.requiredskills.build 
end 

改變這種代碼在控制器
