How can i upload a file in a directory using ruby mine? -

this modal file data_file.rb

    class datafile < activerecord::base   # attr_accessible :title, :body   def self.save(upload)     name =  upload['datafile'].original_filename     directory = "public/data"     # create file path     path = file.join(directory, name)     # write file     file.open(path, "wb") { |f| f.write(upload['datafile'].read) }   end end 

this controller file

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 

and view file

 <h1>file upload</h1> <%= form_tag :action => 'uploadfile'  %> <p><label for="upload_file">select file</label> :   <%= file_field 'upload', 'datafile' %></p> <%= submit_tag "upload" %> <%= end %>

the last line of view file: <%= end %>

you need remove = sign

answer second question

<%= form_tag :action => 'uploadfile' %> faulty

• open console
• cd in application directory: cd \users\pratik\rubymineprojects\upload
• type rake routes

• you see among lot of lines, should resemble (your output may different) :

  upload    /upload(.:format)    upload#index        post   /upload(.:format)    upload#create 

• on left side of "get", note name appear (in example 'upload' may different in output)

• then use name in view form_tag appening _path it, result should have this: <%= form_tag upload_path %>
