Newbie question about POSTing xml file to RESTful rails app
I have a newbie question about creating a new item using REST in rails
1.2.
1. I created my project:
''rails mra -d sqlite3''
2. I generate all I can:
''cd mra''
''script/generate scaffold_resource widget name:string
description:string''
3. I create database stuff:
''rake db:migrate''
4. I now have a basic app:
''script/server''
I create a couple of widgets using the basic scaffolding forms.
5. I browse ''http://localhost:3000/widgets.xml'' I get a nice
xml file
out:
<?xml version="1.0" encoding="UTF-8" ?>
<widgets>
<widget>
<description>baz-ness</description>
<id type="integer">1</id>
<name>baz</name>
</widget>
<widget>
<description>foo-ness</description>
<id type="integer">2</id>
<name>foo</name>
</widget>
</widgets>
6. I can use curl to POST a new widget to the app:
''curl -d "widget[name]=bar" -d
"widget[description]=bar-ness" \
http://localhost:3000/widgets''
With a default app generated this way, is there a way to use curl to
POST an XML file and generate a new widget? I do not think the
''create'' method in widgets_controller.rb distinguishes between
the two
URL''s used for a POST (/widgets and /widgets.xml) as far as how input
is handled, and I am not sure how params[:widget] is populated (other
than knowing that it is not populated correctly when I try something
like this:
''curl -X POST -d \
"<widget><name>foobar</name><description>foobar-ness</description></
widget>" \
http://localhost:3000/widgets''
If I need to add code to parse the input XML file, where is the best
place to code this, as a helper method?

I found that I was not indicating that my Content-Type as ''text/xml'' in my curl command, and that is what is needed to trigger the XML parsing.

Re: Newbie question about POSTing xml file to RESTful rails app
I will have to experiment with just submitting an XML file, but i _thought_ when I tried this w/o the Content-Type header ,it created a null widget: ID only blank attributes.
