所以,我试图更新嵌套对象,但出于某种原因,父控制器的apps_params
并不满意,因为app
不是&#39传递给它。看看下面,让我知道是否应该发布更多代码。
控制台错误如下:
Started PUT "/apps/1" for 127.0.0.1 at 2015-03-21 14:00:12 -0500
Processing by AppsController#update as JSON
Parameters: {"authenticity_token"=>"0Z/SxhhEO6OA6eiShd+1PZI0DQ9QK1I7G8wqoInz+vM=", "@app"=>{"element"=>{"@app"=>{"el

app/controllers/apps_controller.rb:45:in `block in update'
app/controllers/apps_controller.rb:44:in `update'
apps_controller.rb
中引用的行:
def update
respond_to do |format|
if @app.update(app_params)
format.html { redirect_to @app, notice: 'App was successfully updated.' }
format.json { render :show, status: :ok, location: @app }
else
format.html { render :edit }
format.json { render json: @app.errors, status: :unprocessable_entity }
end
end
end
private
def app_params
params.require(:app).permit(:name, :infivewords, :description, elements_attributes: [:name, :description])
end
我的Apps
展示View
:
<% @app.elements.each do |element| %>
<tr>
<td>
<span class="rest-in-place" data-url="<%= url_for @app %>" data-object="@app[element]" data-attribute="@app[element.name]" data-placeholder="Enter description">
<%= element.name %>
</td>
<td><h2><%= element.description %></h2></td>
我已经无休止地试图弄清楚View
,试图弄清楚为什么app_id
没有通过,但我感到茫然,并且似乎无法找到我在任何地方寻找的信息。
感谢任何帮助。谢谢。
编辑:我应该在我的路线中添加它,我有两个独立的资源块。一个元素在应用程序内部,另一个元素在元素内部。我回到办公桌后,我会发布代码。
EDIT2 - 应用表单视图:
<%= form_for(@app) do |f| %>
<% if @app.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(@app.errors.count, "error") %> prohibited this app from being saved:</h2>
<ul>
<% @app.errors.full_messages.each do |message| %>
<li><%= message %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
<%= f.label :name %><br>
<%= f.text_field :name %>
</div>
<div class="field">
<%= f.label :infivewords %><br>
<%= f.text_field :infivewords %>
</div>
<div class="field">
<%= f.label :description %><br>
<%= f.text_area :description %>
</div>
<div class="actions">
<%= f.submit %>
</div>
<% end %>
答案 0 :(得分:1)
我对rest_in_place不熟悉,但我会仔细检查这一行的数据属性
<span class="rest-in-place" data-url="<%= url_for @app %>" data-object="@app[element]" data-attribute="@app[element.name]" data-placeholder="Enter description">
也许更像是
<span class="rest-in-place" data-url="<%= url_for @app %>" data-object="app[elements]" data-attribute="name" data-placeholder="Enter description">
