when i tried to crate an upload file application in rails i am getting error like this

Template is missing

Missing template app\views\upload\uploadfile.html.erb in view path app/views

this is ma model

class DataFile < ActiveRecord::Base   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

this is ma view file

<h1>File Upload</h1> <%= start_form_tag ({:action => 'uploadFile'},                         :multipart => true) %> <p><label for="upload_file">Select File</label> : <%= file_field 'upload', 'datafile' %></p> <%= submit_tag "Upload" %> <%= end_form_tag %>

This is ma controller

class UploadController < ApplicationController   def index puts 'hiiiiiiiiiii'      render :file => 'app\views\upload\uploadfile.html.erb' puts 'hiiiiiiiiiii2'   end   def uploadFile puts 'hiiiiiiiiiii3'     post = DataFile.save(params[:upload])     render :text => "File has been uploaded successfully"   end end

I think use render :file => ‘uploadfile.html.erb’, as rails would look for the template in your view directory, which is “app/views”,

and if you use render :file => ‘controller/uploadfile.html.erb’, it will look for the template in “app/views/controller/uploadfile.html.erb”, or rails always

assume you have already put your template in the controller’s according view folder

NoMethodError (You have a nil object when you didn't expect it! You might have expected an instance of ActiveRecord::Base. The error occurred while evaluating nil.):

Did you add uploadFile to route.rb?

And i think you’d better follow rails’ convention, instead of writing code as like using some other frameworks

hi yong i got the same proble and solved it ,

you can use in form tag uploadfile instead of uploadFile

and in render file : use #"{root_url}/app/view/--path"

hope you will solve it .. thanks
