我的目标是半定期更新网站的about部分。我想使用命名资源来做这件事。我的问题是表单不会保存到数据库，并在我单击“创建文本”按钮后转发到about页面。
我看过我的路线，控制器和视图，但我不知道我做错了什么。任何帮助表示赞赏。
这是控制台输出：

这是about.html.erb视图：
1 <div id="container_about">
2 <%= image_tag "chocolate_lady.jpg", id: "about_image" %>
3 <div id="right_column_about" >
4 <h1> Who we are </h1>
5 <%= @text1.text %>
6 <br />
7 <br />
8 <%= @text2.text %>
9 <br />
10 <br />
11 <%= @text3.text %>
12 </div>
13 </div>
以下是表单视图：
4 <%= flash[:notice] %>
5 <%= flash[:status] %>
6
7 <%= form_for @about, :url => { :action => 'save_about'} do |f| %>
8
9 <div class="field">
10 <%= f.label :title %><br />
11 <%= f.text_field :title %>
12 </div>
13 <div class="field">
14 <%= f.label :text %><br />
15 <%= f.text_area :text %>
16 </div>
17
18 <div class="actions">
19 <%= f.submit %>
20 </div>
21 <% end %>

表单html：
<form accept-charset="UTF-8" action="/about" class="new_text" id="new_text" method="post"><div style="margin:0;padding:0;display:inline"><input name="utf8" type="hidden" value="✓"><input name="authenticity_token" type="hidden" value="kmkSyhhqrHiwtIEMd8R1+EEh1ic7688h7lNFW9FnMUM="></div>
<div class="field">
<label for="text_title">Title</label><br>
<input id="text_title" name="text[title]" size="30" type="text">
</div>
<div class="field">
<label for="text_text">Text</label><br>
<textarea cols="40" id="text_text" name="text[text]" rows="20"></textarea>
</div>
<div class="actions">
<input name="commit" type="submit" value="Create Text">
</div>
</form>
这是我的佣金路线：
product_photos GET /product_photos(.:format) product_photos#index
POST /product_photos(.:format) product_photos#create
new_product_photo GET /product_photos/new(.:format) product_photos#new
edit_product_photo GET /product_photos/:id/edit(.:format) product_photos#edit
product_photo GET /product_photos/:id(.:format) product_photos#show
PUT /product_photos/:id(.:format) product_photos#update
DELETE /product_photos/:id(.:format) product_photos#destroy
root / static_pages#home
products /products(.:format) ProductPhotos#index
about /about(.:format) static_pages#about
contact /contact(.:format) static_pages#contact
policy /policy(.:format) static_pages#policy
new_text /about/new(.:format) static_pages#new_about
show_text /about/:id(.:format) static_pages#show_about
POST /about(.:format) static_pages#save_about
以下是我的路线：
7 match '/products' => 'ProductPhotos#index'
8 match '/about' => 'static_pages#about'
9 match '/contact' => 'static_pages#contact'
10 match '/policy' => 'static_pages#policy'
11 match '/about/new/' => 'static_pages#new_about', :as => :new_text
12 match '/about/:id' => 'static_pages#show_about', :as => :show_text
13 match '/about/' => 'static_pages#save_about', via: 'post'
这是我的控制器：
12 def show_about
13 @about = Text.find(params[:id])
14
15 respond_to do |format|
16 format.html
17 format.json { render json: @about }
18 end
19 end
20
21 def new_about
22 @about = Text.new
23 respond_to do |format|
24 format.html # new_about.html.erb
25 format.json { render json: @about }
26 end
27 end
28
29 def save_about
30 @about = Text.new(params[:text])
31
32 respond_to do |format|
33 if @about.save
34 format.html { redirect_to show_about_path(@about), notice: 'Product photo was successfully created.' }
35 format.json { render json: @about, status: :created, location: @about }
36 else
37 format.html { redirect_to action: 'new_about', notice: 'Product photo wasn\'t save'}
38 format.json { render json: @about.errors, status: :unprocessable_entity }
39 end
40 end
41 end

答案 0 :(得分：3)
8 match '/about' => 'static_pages#about'与13 match '/about/' => 'static_pages#save_about', via: 'post'
由于它们都匹配/about而通用的是第一个，因此将使用这个。将更具体的路由放在match '/about/' => 'static_pages#save_about', via: 'post'之后，将通用路由放在后面，或者更改通用路由以使其听取:get之类的match '/about' => 'static_pages#about', via: :get。通过专门添加:get，它永远不会消耗:post。
基本上，当您运行rake routes时，您希望查看每个路径的HTTP方法，例如
users GET /users(.:format) users#index
POST /users(.:format) users#create
new_user GET /users/new(.:format) users#new
edit_user GET /users/:id/edit(.:format) users#edit
