我是铁杆新手,我遇到了一个我似乎无法理解的问题。我将解释我的情景:
我有一个使用Devise创建的用户模型。我创建了另一个名为Skill的模型(数学:整数科学:整数),它引用了用户:
- skill belongs_to :user
- user has_one :skill
我修改了路径文件,以便该技能在用户中嵌套了路径:
# Users (Devise)
devise_for :users, :path_names => { :sign_up => "register"}
# Skills
resources :users do
resource :skills
end
我创建了一个SkillsController,其中包含动作编辑和更新。代码如下:
class SkillsController < ApplicationController
def edit
@user = User.find(params[:user_id])
@skill = get_skill(@user)
end
def update
@skill = Skill.find(params[:id])
if (@skill.update_attributes(params[:skill]))
redirect_to(root_url, {:notice => 'Your skills were successfully updated.'})
else
render :action => "edit"
end
end
# the user might have been created without skills, so it will be nil on the first usage
# ToDo: extend Devise UserController to create an empty skill on the create action
def get_skill(user)
if !(user.skill)
user.skill = Skill.new
user.save
end
user.skill
end
end
最后,我的观点/技能/ edit.html.erb视图如下所示:
<%= form_for(@skill) do |skill_form| %>
<div>
<%= skill_form.label :math %><br />
<%= skill_form.text_field :math %>
</div>
<div class="actions">
<%= skill_form.submit 'Save' %>
</div>
<% end %>
每当我尝试使用技能编辑表单(http:// localhost:3000 / users / 1 / skills / edit)时,都会抛出以下错误:
ActionController::RoutingError in Skills#edit
No route matches {:controller=>"skills"}
Extracted source (around line #1):
1: <%= form_for(@skill) do |skill_form| %>
2:
3: <div>
我知道我一定做错了什么......只是弄不清楚:|

您的get_skill
方法应该创建这样的技能:
def get_skill
user.skill || user.create_skill
end
form_for
因为你已经在路线中的用户中嵌套技能应该是这样的:
<%= form_for [@user, @skill] do |f| %>
答案 1 :(得分:0)
从以下位置更改form_for:
form_for(@skill)
为:
form_for([@skill.user, @skill])
