这是我的模态文件data_file.rb
class DataFile < ActiveRecord::Base
# attr_accessible :title, :body
def self.save(upload)
name = upload['datafile'].original_filename
directory = "public/data"
# create the file path
path = File.join(directory, name)
# write the file
File.open(path, "wb") { |f| f.write(upload['datafile'].read) }
end
end
这是我的控制器文件
class UploadController < ApplicationController
def index
render :file => 'app\views\upload\uploadfile.html.erb'
end
def uploadFile
post = DataFile.save(params[:upload])
render :text => "File has been uploaded successfully"
end
end
这是我的查看文件
<h1>File Upload</h1>
<%= form_tag :action => 'uploadFile' do %>
<p><label for="upload_file">Select File</label> :
<%= file_field 'upload', 'datafile' %></p>
<%= submit_tag "Upload" %>
<%= end %>
每当我尝试使用语法http://127.0.0.1:3000/upload/index
访问视图文件时,我都会收到以下错误
显示C:/Users/pratik/RubymineProjects/upload/app/views/upload/uploadfile.html.erb第6行引发:
C:/Users/pratik/RubymineProjects/upload/app/views/upload/uploadfile.html.erb:6: syntax error, unexpected keyword_end

这个项目是tutorialpoints.com上的一个示例项目。但是,当我尝试这样做时,它失败了。我使用ruby mine作为IDE。有人可以指导我吗?这将是非常有帮助的。
答案 0 :(得分:0)
视图文件的最后一行:<%= end %>
您需要删除=
标志
回答您的第二个问题
<%= form_tag :action => 'uploadFile' do %>
错误
cd
:cd \Users\pratik\RubymineProjects\upload
rake routes
你会在许多行中看到一些类似于(你的输出可能不同)的东西:
upload GET /upload(.:format) upload#index
POST /upload(.:format) upload#create
,请注意显示的名称(在我的示例中,其中&#39;上传&#39;您的输出可能会有所不同)
form_tag
中使用此名称_path
,因此您应该使用此类名称:<%= form_tag upload_path do %>
