CONTROLLER

CREATE

  def create
    set_cache_buster
    @court_agency = CourtAgency.new(court_agency_params)
    @court_agency.created_by = current_user
    @court_agency.updated_by = current_user
    binding.pry
    respond_to do |format|
      if @court_agency.save
        flash[:success] = 'Court was successfully created.'
        format.html do
          redirect_to court_agencies_path
        end
        format.js { render :js => "window.location = '#{court_agencies_path}'" }
      else
        format.json { render json: @court_agency.errors, status: :unprocessable_entity }
      end
    end
  end

更新

  def update
    set_cache_buster
    @court_agency = CourtAgency.find(params[:id])
    @court_agency.updated_by = current_user
    respond_to do |format|
      if @court_agency.update_attributes(court_agency_params)
        flash[:success] = 'Court was successfully updated.'
        format.html do
          redirect_to court_agencies_path
        end
        format.js { render :js => "window.location = '#{court_agencies_path}'" }
      else
        format.json { render json: @court_agency.errors, status: :unprocessable_entity }
      end
    end
  end

强有力的参数

  def court_agency_params
    params.require(:court_agency).permit(
      :type,
      :subtype,
      :division,
      :associate_justice,
      :presiding_justice,
      :map,
      :landmark_image,
      ]
    ) if params[:court_agency]
  end

我的观点

= form_for(@court_agency, remote: true, html: { :multipart => true, class: 'form-horizontal ajax-form', style: 'margin-bottom: 0;', 'data-model-name' => 'court_agency'}) do |f|
    .form-group
      = f.label :landmark_image, 'Landmark', class: 'control-label'
      %br/
      = f.file_field :landmark_image, class: 'btn btn-warning'
      - if @court_agency.map.present?
        = image_tag @court_agency.map.url(:small), class: 'img-responsive img-thumbnail'
    .form-group
      = f.label :map, 'Map', class: 'control-label'
      %br/
      = f.file_field :map, class: 'btn btn-warning'
      - if @court_agency.map.present?
        = image_tag @court_agency.map.url(:small), class: 'img-responsive img-thumbnail'

MODEL

  #Paperclip
  has_attached_file :map,
                    :styles => { :large => "900x900>", :medium => "300x300>", :thumb => "196x196>", :small => '50x50>' },
                    :default_url => ActionController::Base.helpers.asset_path('missing.png'),
                    :url => "/assets/court_agencies/:id/:style/:basename.:extension",
                    :path => ":rails_root/public/assets/court_agencies/:id/:style/:basename.:extension"
  validates_attachment_content_type :map, :content_type => /\Aimage\/.*\Z/
  has_attached_file :landmark_image,
                    :styles => { :large => "900x900>", :medium => "300x300>", :thumb => "196x196>", :small => '50x50>' },
                    :default_url => ActionController::Base.helpers.asset_path('missing.png'),
                    :url => "/assets/court_agencies/:id/:style/:basename.:extension",
                    :path => ":rails_root/public/assets/court_agencies/:id/:style/:basename.:extension"
  validates_attachment_content_type :landmark_image, :content_type => /\Aimage\/.*\Z/

好的，这就是问题所在：

当我创建没有文件上传时，它可以工作。但是当我附上文件时，params不工作而且它留空了。所以当我绑定.pry：

[1] pry(#<CourtAgenciesController>)> params
=> {"action"=>"create", "controller"=>"court_agencies"}

Params失踪。

当我在没有文件上传的情况下更新时，它可以工作。但是当我附加文件时，错误是：

Started POST "/court_agencies/53" for 127.0.0.1 at 2015-04-08 16:03:21 +0800

ActionController::RoutingError (No route matches [POST] "/court_agencies/53"):

或者就像

Routing Error
No route matches [POST] "/court_agencies/53"

在浏览器上。

我安装了remotipart。还有Paperclip。

请帮忙。非常需要它。

更新

途径：

  #COURT AGENCY
  resources :court_agencies do
    member do
      get 'list'
      put 'update_uin'
    end
    collection do
      get 'get_court_agency_list'
      get 'court_agency_list'
      get 'add'
      get 'get_uin'
    end
  end

此问题与remote: true有关。如何通过带文件上传的ajax创建/更新提交？

Answer 1

你是否在你的模型中定义了attr_accessible ...我没有在你的模型中看到

attr_accessible: :type,:subtype,:division,:associate_justice,:presiding_justice,:map,:landmark_image,
