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

# File Upload
\<%= start\_form\_tag ({:action =\> 'uploadFile'}, :multipart =\> true) %\>

Select File : \<%= file\_field 'upload', 'datafile' %\>

\<%= 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

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
