UPDATE — just figured out why the xml isn’t showing up after some googling!

Maybe the OP can correct me if I’m wrong, but you’ll need to add a format to the controller file for the model you’re using. Just edit the controller file and add

format.xml{ render xml: @model_name }

after the format.html. There should be one there fore json that’s why you’re getting json results and html results. Try again and it should work :)

@cam – Are you running mysql from the mysql command line? or just typing mysql > into the CL on linux/windows? if so, you gotta start the mysql command line

@moosya – ditto… any help on this matter would be excellent! I’m getting an error that says “error on line 1 at column 1: Extra content at the end of the document”… I hit ctrl+u and it’s empty source code.

Great post! thanks!

For some reason when I query for the “.xml” content nothing is returned
So, for example, this cmd does not work curl http://localhost:3000/employees.xml
but the same one w/o the “.xml” returns the html.

Is there a special command or flag to ensure that xml is generated also?

Thanks for posting this!

I’m sure I”m missing something easy, but I’m hung up after getting mysql2 installed. I’m in my app’s root directory and I’m using bash. When I try to create the database I get a bash error saying command not found. Any suggestions?

$ mysql> create database rest_api
-bash: mysql: command not found

How hard would it be to turn this XML to JSON? Great Article either way!

Akshay,

This tutorial would do exactly what you need. It sends an xml file to the Server (host/url) for you; instead of CURL.

Hi There,

I would like to send .xml files to web service. I have been able to generate/write xml into a file and would like to use that file to be sent over HTTP.

My curl command is something like
curl -F “SUBMISSION=@submission.xml” -F “STUDY=@study.xml” -F “SAMPLE=@sample.xml” “https://somesite.com/submit/box”

Is it possible using the tutorial you have explained.

Thank you

Thanks for this tutorial! I was completely in the dark about how XML requests would work in Rails but now I’ve got an inkling.

@Dillon, the server console gave me a clue with “Processing by EmployeesController#show as XML”. In the employees_controller.rb, I added the line “format.xml { render :xml => @employee }” in the show def. Interesting… I can curl with .json extension and I get the format that’s been requested for the project I’m working on.

@Dillon, Thanks, I was brain dead, and not typing “ruby” before the command. Create works, but the other 3 – no luck. I went back to the curl …/employees.xml, I get nothing. If I use the curl command omitting .xml, I get a response with the html. Ruby 1.8.7 (I did add the require above), gem 1.8.11 and Rails 3.1.1

Thanks for your help. This has been a great boost in my learning RoR!

@Chris: See the step “Create a file named api_client.rb in the root of the rest_api rails app”. Then open a Terminal (shell) or command prompt (Windows), run the script. IE: 1) $ cd /where_you_put_your_rails_app 2) $ ruby api_client.rb . If the script doesn’t run, make sure ruby is in your path. If you have other problems, just respond.

“Now run with ruby api_client.rb and you should see:” I’ve obviously missed something. If I run read from terminal in /rest_api, it just looks at me. What am I supposed to run?

ok, rigth. thanks!

@Ronaldo, Yes you can use webservices to bridge languages. .NET can consume a webservice as a REST client and Rails can serve the REST service.

Hi.
Thank you so much. This example helps a lot.
A question: i could send the xml file to web service built in .net, for example?

That’s true. 1.8.7 needs the rubygems require. 1.9 does not. Thanks for the feedback!

create tutorial!

i am new to ruby/rails (come from a c/c++/corba, java/rmi/jee/spring background).

everything was easy to understand and everything ran as define with the exception of the client.

i had to add the require ‘rubygems’ before it would run (see below). however, i am using snow leapord with ruby 1.8.7 and gem 1.3.7

require ‘./lib/api.rb’
require ‘rubygems’
require ‘nokogiri’

again great tutorial; just added in case someone else had the same problem.
