适用于相关模型的Rails Form_中的路径问题

Question

我正在研究一个项目，我必须在该项目中分析文件中的数据，用户应该能够上传。我有一个模型输入文件，并选择为我的分析模型实施分析_FACADE，该模型捆绑了大多数功能。这是模型

#app/models/analysis.rb
class Analysis < ApplicationRecord
  has_one :input_file, dependent: :destroy
end
#app/models/input_file.rb
class InputFile < ApplicationRecord
  belongs_to :analysis
  has_many :access_data, dependent: :destroy
  def uploaded_file=(file_field)
    self.name = File.basename(file_field.original_filename).gsub(/[^w._-]/,'')
    self.content_type = file_field.content_type.chomp
    self.data = file_field.read
  end
end

我的分析controller和相应的立面模式

来了

#app/controllers/analyses_controller.rb
class AnalysesController < ApplicationController
  before_action :set_analysis, only: :show
  def show
    @analysis_facade = AnalysisFacade.new(@analysis)
  end
  private
  def set_analysis
    @analysis ||= Analysis.create
  end
end
#app/facades/analysis_facade.rb
class AnalysisFacade
  attr_reader :analysis
  def initialize(analysis)
    @analysis = analysis
  end
  def new_input_file
    @input_file = analysis.build_input_file
  end
  def input_file
    @input_file ||= new_input_file
  end
  def access_data
    @access_data ||= analysis.input_file.access_data
  end
end

我的输入文件控制器

#app/controllers/input_files_controller.rb
class InputFilesController < ApplicationController
  include LogFileScanner
  before_action :set_analysis, only: [:new, :create, :update]
  def new
    @input_file = Input_file.new
  end
  def create
    @input_file = @analysis.build_input_file(input_file_params)
    if @input_file.save
      access_data = scan(@input_file.data)
      @input_file.access_data.create(access_data)
    end
  end
  def update
    @input_file = @analysis.input_file
    if @input_file.update
      access_data = scan(@input_file.data)
      @input_file.access_data.update(access_data)
    end
  end
  private
  def input_file_params
    params.require(:input_file).permit(:uploaded_file, :analysis_id)
  end
  def set_analysis
    @analysis = Analysis.find(params[:input_file][:analysis_id])
  end
end

对于文件上传，我有这些视图

#app/views/analyses/show.html.erb
<%= render template: 'input_files/get' %>
#app/views/input_files/get.html.erb
<%= form_with model: [@analysis_facade.analysis, @analysis_facade.input_file], action: :update, html: {multipart: true, class: 'form-horizontal center'} do |form| %>
  <div class='form-group.new'>
    <% if false %>
      <%= form.hidden_field :analysis_id, value: @analysis_facade.analysis[:id] %>
    <% end %>
    <%= form.file_field 'uploaded_file' %>
    <%= form.submit "Upload", class: 'btn btn-default btn-primary' %>
  </div>
<% end %>

执行此导致错误

undefined method `analysis_input_files_path' for #<#<Class:0x00007f1208040288>:0x00007f11f0d71d48>
Did you mean?  analysis_path

对于此loc

<%= form_with model: [@analysis_facade.analysis, @analysis_facade.input_file], action: :update, html: {multipart: true,
class: 'form-horizontal center'} do |form| %>

为什么？我需要将Analysis_ID传递给参数，以创建新的InputFile。但是我希望它比手动添加隐藏式field的清洁，因为Model_with应该提供此功能。我在这里想念什么？

另外：为什么Rails搜索" Analysis_input_files_path"？它显然是一个has_one关系，所以它不应该寻找分析_input_file_path吗？

Answer 1

我是一个概念上的错误。我将立面模型更改为

class AnalysisFacade
  attr_reader :analysis
  def initialize(analysis)
    @analysis = analysis
  end
  def new_input_file
    @analysis.build_input_file
  end
  def input_file
    @analysis.input_file ||= new_input_file
  end
  def access_data
    @analysis.input_file.access_data
  end
end

现在像这样的视图

<%= form_with model: @analysis_facade.input_file, html: {multipart: true, class: 'form-horizontal center'} do |form| %>
  <div class='form-group.new'>
    <%= form.file_field 'uploaded_file' %>
    <%= form.submit "Upload", class: 'btn btn-default btn-primary' %>
  </div>
<% end %>
