Updating a page using script/runner

Ruby Apps Radiant CMS
1

Dear All,

Thanks for the kind lessons on how to add a page using script/runner. I
have the following working script to create such a new page:

------ start of script to add a new page —

parent = Page.find_by_url(’/services/news’)
child = parent.children.build(:title => “Floods”,
:breadcrumb => “Floods”, :slug => “floods”)
child.parts.build(:content => “This is a page for flood news”,
:name => “body”)
child.save!

------ end of script to add a new page —

How may I update the contents using script/runner? I have tried
the following, but it does not work. Any help to solve this
would be much appreciated.

---- test script that does not work

floods = Page.find_by_url(’/services/news/floods’)
floods.parts.build(:content => “This is now for droughts”)
floods.update

thanks in advance,

saji

Saji,

You might try using “create” instead of “build”. In that case, it could
look like this:

parent = Page.find_by_url(‘/services/news’)
child = parent.children.create(:title => “Floods”, :breadcrumb =>
“Floods”, :slug => “floods”)
child.parts.create(:name => “body”, :content => “This is a page for
flood news”)

Keep in mind that create and build might not work if the collection is
empty or the original object is unsaved [1]. Your other alternative is
to build the objects manually, then push it into the collection:

parent = Page.find_by_url(‘/services/news’)
child = Page.new(:title => “Floods”, :breadcrumb => “Floods”, :slug =>
“floods”)
part = PagePart.new(:name => “body”, :content => “This is a page for
flood news”)
parent.children << child
child.parts << part

Also note in your second snippet that your part needs a name.

Sean,

Thanks very much for the advice. On using “create” and then “update”,
I found that duplicate body “parts” were being “created” every time I
ran
the code. So running the script 5.times resulted in 5 “body parts” for
the
same page. After some experiments, here is what I found to suit my
purposes ( replacing a part of the page with new stuff). Esp. used
the “clear” method to wipe the page parts clean

------------

floods=Page.find_by_url(‘/services/news/floods’)
floods.parts.clear # wipe clear the flood page of its parts
floods.parts.create(
:content => “Now for floods and droughts”,
:name => “body”
)
floods.update

------------

Dear All,

floods = Page.find_by_url(‘/services/news/floods’)

Saji,

Interesting, that would make sense. You could also do
floods.parts.find_or_initialize_by_name(“body”) if you don’t want to
drop the parts.

I’m resurrecting an old thread just before starting to look at it
myself. I’m likely to work on a project where it will be needed to
update a large number of pages. I think it may be possible to dump the
content out to a bunch of files from where it should be possible to pick
up the pages, add the usual stuff and update the pages to a Radiant site
using a script.

Is there anyone doing so using the script below or something similar?
Would it be possible to share?

I’ve never used script/runner with a live site but I’m willing to look
at the relevant stuff in the Rails world to make that happen. But I’m
just starting to wonder how to keep this site scalable (since it
involves the migration of about 7 books from PDF to Radiant) with a
bunch of relatively standard things to be included on each page.

Thanks,
Mohit.

Thanks Saji,

It serves as a great example to see-and-learn!!

Cheers

Hi Mohit,

We control our own server, and it is easy to do stuff like this.
Here is a script that I use to update or add certain parts of our
website (currently offline).

Hope it is helpful.

Looking at this answers the fundamental question I had!! I was
concerned about how the authentication is handled to get past the
admin. But, of course, when we use script/runner, we’re usually
accessing the models directly rather than through the controllers - and
the controllers are where the before_filters for authentication will
usually be!

That said, I guess this means that it’s best for the script to be local
to the site - so, I can’t get it to submit from my desktop to the server
machine. The script should ideally be on the server where the site is
running.

Is this how you’re using it, Saji?

machine. The script should ideally be on the server where the site is
running.

Well, the web-server is a different machine, but we have
full access to it. We run a drb server on the
web-server and installed clients on other machines. Users upload
stuff from their desktops to the webserver through this mechanism.

I remember Sean’s advise that you may be able to use Capistrano
for this purpose. That may be worth checking out.

Anyway, I am attaching scripts for the client and servers
we use.

best wishes,
saji

— this is the drb server that sits at the web-server

#!/usr/bin/env ruby

require ‘drb’
require ‘drb/acl’

@baseDir=ENV[‘RadiantHOME’]+“/customScripts”

this order is important, so do not move the

the require statement below

require File.join(File.dirname(FILE), ‘server_methods’)

puts “Will Exit if not executed in right Directory”
exit unless pwd.chomp == @baseDir

if FILE == $0
acl = ACL.new(%w( deny all allow 190.1.1.121 allow 220.84.94.58 allow
localhost ) )
DRb.install_acl(acl)
DRb.start_service(“druby://:7777”, OurClass.new)
puts “Drb server running at #{DRb.uri}”
trap(“INT”) {DRb.stop_service }
DRb.thread.join
end

— some methods used by the DRb object

require ‘net/ftp’

class OurClass

def chDir(wDir,year,month)
wDir=“/home/saji/MyTestServer/public/Reports/”+wDir+“/”+year+“/”+month
mkdir -p #{wDir}
@wDir=wDir
end

def ftpFiles(ftpsite,login,password,wDir,txt,img)
“Opening new ftp session for #{ftpsite}”
ftp=Net::FTP.new(ftpsite)
ftp.login(user=login,passwd=password)
ftp.chdir(wDir)
“Retrieving Image files”
ftp.getbinaryfile(img,@wDir+“/”+img)
“Retrieving Text files”
ftp.gettextfile(txt,@wDir+“/”+txt)
ftp.close
“ftp over”
end

def updateWeb(service,year,month)
# run an update
retVal=[]
ENV[‘RAILS_ENV’]=“production”
ls = IO.popen(“…/script/runner updateWeb #{year} #{month}
#{service}”,“r”)
while line = ls.gets
retVal << line
puts line
