我正在开发一个项目，我必须分析文件中的数据，用户应该可以上传。我有一个模型InputFile并选择为我的Analysis模型实现一个analyze_facade，它捆绑了大部分功能。 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
这是我的AnalysisController和相应的外观模式
#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InputFiles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，我有这些观点
#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 %>
执行此操作会导致错误
undefined method `analysis_input_files_path' for #<#<Class:0x00007f1208040288>:0x00007f11f0d71d48>
Did you mean? analysis_path
这个地方
<%= 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params以创建新的InputFile。但我希望它比手动添加hidden_field更清洁，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＆＃39;？它显然是一个has_one关系，所以它不应该找分析_input_file_path吗？

答案 0 :(得分：0)
我是一个概念上的错误。我将立面模型改为
org.openqa.selenium.WebDriverException: setWindowRect
视图现在就像这样
