Rails - 當輸入不爲空時，名稱不能爲空白錯誤

嘗試更新a時，出現'Name can not be blank'和'Name only只允許字母，數字和' - ''的錯誤名稱。這工作正常，但我剛剛經歷了一遍，同時寫了一個測試，並意識到它不再工作，我無法弄清楚爲什麼或改變了什麼以打破它。Rails - 當輸入不爲空時，名稱不能爲空白錯誤

分類控制器

def update 
    if @category.update category_params 
    redirect_to new_guide_category_item_path(@guide, @category) 
    flash[:info] = "Updated successfully" 
    else 
    render 'edit' 
    end 
end 

private 

def category_params 
    params.require(:category).permit(:name, :template)   
end

edit.html.erb

<%= render 'shared/error_messages', object: f.object %> 
     ..... 
<%= form_for([@guide, @category], url: guide_category_path) do |f| %> 


    <%= f.label :name, "Category name" %> 
    <%= f.text_field :name %> 

    <%= f.label :template, "Template" %>  
    <%= f.text_area :template, { :id => 'edit' } %> 

    <%= f.submit "Save", :value => "Save Template" %> 

<% end %>

模型

validates :name, presence: true, length: { maximum: 255 }, uniqueness: { scope: :guide_id, case_sensitive: false }, 
    exclusion: { in: %w(guide guides category categories item items page pages post posts tag tags key keys item key item keys item-key item-keys item_key item_keys mod moderator mods moderators admin admins), message: "%{value} cant be taken." }, 
    format: { with: /\A[a-zA-Z0-9 -]+\z/, message: "only allows letters, numbers, spaces and '-'" }

條路線

resources :guides do 
    resources :categories, only: [:new, :create, :edit, :update] do 
    end 
end

任何人有什麼可能會錯誤的想法？

當您嘗試更新類別時，您可以粘貼您的日誌嗎？ – JCorcuera

@JCorcuera https://docs.google.com/document/d/1u9yr5vkeuKmTd9clOJb7LID7PDOIqRyy50KeL-CZrWM/edit?usp=sharing將其放入此Google文檔中。 – Rob

請不要讓人們爲了幫助你而跳過籃球。編輯您的問題以包含日誌輸出。 – MarsAtomic

您需要在局部添加error_messages幫手標籤。這將處理所有錯誤信息並正確顯示。

在視圖中有一個，但不是直接在表單中。 – Rob

它應該在窗體中或有權訪問實例變量。 –

它看起來像你的數據庫有一個同名的現有記錄。嘗試輸入一個唯一的名稱。在您的模型中，它檢查：唯一性。
