It looks like git://github.com/xgamerx/active_form.git no longer exists.

Try running the first step but with http://github.com/cs/active_form/tree/master. i.e. script/plugin install git://github.com/cs/active_form.git

(This is one of the unfortunate aspects of rails and many ruby programmers. Plugins and gems move around often. The first place I always look for the latest stuff is on github)

uninitialized constant ActiveForm

maye some clue what’s going wrong?

It looks like the path should be https://yourbucketname.s3.amazonaws.com/videos/
instead of
https://s3.amazonaws.com/yourbucketname/videos/

It’s coming along, but very slowly lately. I been pre-occupied with rebranding my Spitfire Sky company, and putting together plans and funding for its future.

Are you on the waiting list or a user already?

Coincidentally, Hemet Flight School (where I fly out of) uses your Flight Schedule Pro software. The next app I want to start work on months down the road is actually a scheduling app to compete with yours =). Hemet Flight Center have had some qualms with it, and I do too =).

Thanks for sharing the video. That is brilliant in its simplicity.

How is the logbook product coming along?

For those interested, replace:
redirect_to ‘/404.html’

with:
render :text => ‘401 Unauthorized’, :status => 401

Try out Sphinx. There is a great screencast by Ryan Bates on how to get it setup: http://railscasts.com/episodes/120-thinking-sphinx

And once you’ve got it set up, you can configure it to search across multiple models. Take a look at the last comment on http://freelancing-gods.com/posts/a_concise_guide_to_using_thinking_sphinx for how to do that.

how to do plz suggest

thank you

My intention was to confuse the spammer, but maybe that’s not fundamentally correct or even doing any good. However, I didn’t really feel like it was an authorization issue either (in terms of log in and out) so at the time I chose the 404.

Further thoughts?

Thanks for posting this, I finally got it!

:runner is a variable to make sure Capistrano runs the scripts as a specific user with adequate permissions. On some servers I’ve found I’ve needed it and others simply the :user has worked.

:domain is used by Capistrano to access the the server via ssh. Usually therefore, the domain matches the web address for a virtual host setup. However, at the time we hadn’t registered the domain and were only able to access the server via it’s ip address. I was forced to set :domain to the ip address. However, I still had my server configured to use uniteddev.com for the virtual host (http://articles.slicehost.com/2008/4/29/ubuntu-hardy-apache-virtual-hosts-1) so I temporarily created a variable called site_url to solve the issue. I placed this in the deploy location (:deploy_to, “/home/#{user}/public_html/#{site_url}”). Then after we registered the domain name, I changed ’site_url’ to ‘domain’.

Yes, the repository was on my local machine for this setting. Typically, you set this to a remote git repository location like github.

Yes, ‘deploy_via :copy’ archives the local repository, uploads the archive onto the server, and then extracts the archive into your deploy_to location. This is a rarely used tactic. Usually, git repositories are hosted remotely and deployed via ‘remote cache’.

been looking for something like this around the net. It seems hard to find details on each of the configuration options in deploy.rb. Every example I’ve seen is completely different! This is similar to what I’d like to do. Just got a couple of questions if you don’t mind:

what’s :runner for?
what’s the benefit of setting the :domain and the :site_url separately (most I’ve seen just have domain, and they put in the site url as the domain)?
Is the link in :repository on your local machine?
And if so, does :deploy_via, :copy simply copy the repository from your local machine to the server each time?

Thanks for any help,

it’ll set you up with data-objects, dm-core, and a few of the most frequently used gems from dm-more

simple as that

At first I got an error from godaddy:

def send_mail
if request.post?
Emailer::deliver_contact_email(params[:email])
redirect_back_or_default(’/')
flash[:notice] = “Message sent, thanks very much etc etc etc”
end

Now your users will know if the mail was sent. I needed the redirect_back_or_default(’/') statement in my controller too as I was getting a ‘template missing error’ without it.

Thanks again

I did things a little differently from yourself because I already have an ActionMailer set up to handle signup emails and activation codes (a la restful_authentication) and I have been using the very same smtp_tls.rb file that you use in your tutorial. Nice little bit of code that. I do appreciate it.

I put the gmail configuration stuff you mention at the end of my environment.rb file and then I put my own personal gmail details in the file you specify - this way my site can send and receive emails.

Anyway, this was a good tutorial, it worked right away, cheers.
I am in the middle of throwing my own site together right now and it only took me 20 minutes to get the contact form working, and that includes the 16 or so minutes spent reading the football scores on bbc.com.

Thanks again,

Taken from http://griffin.oobleyboo.com/archive/ruby-enterprise-edition-gem-install-script/ with the addition of sudo user.

Talk to the guys on #merb channel, but I think installing merb is now as easy as “sudo gem install merb”

It seems this now (as of October 28 2008) will create a gems folder and install the gems there, not install them globally.

Also, just realized my blog strangled the > sign so everywhere you see > it should be the actually greater than sign >.

Cheeers!

I’m trying to integrate the yui_editor with the in_place_editing-plugin.

I’m calling:

var editor = new YAHOO.widget.#{editor_class}(textAreaId,#{options[:editor_config_javascript] || ‘{}’});
editor.render();
global_editors.push( editor );

From controls.js

But I getting an error saying that global_editors is undefined.

When I use the plugin as intended (rendering rich editor fields onLoad) it works, but I can’t figure out where global_editors is defined…? Is global_editors some kind of global js-variable? And if that’s the case, why isn’t defined in my new context?

Many thinks in advance,
Kind regards,

Mauth, now merb-auth is now available in the merb-more repo.

PDF::HTMLDoc.program_path=”/opt/local/lib/ruby/gems/1.8/gems/htmldoc-0.2.1/lib/htmldoc”

Now the program runs, although results with no joy.

page.body does have content, however no pdf is created.

Insight appreciated, thanks!

Thank you for the examples.

When trying to run the first example I get the error:

/opt/local/lib/ruby/gems/1.8/gems/htmldoc-0.2.1/lib/htmldoc.rb:182:in `execute’: Invalid program path: htmldoc (PDF::HTMLDocException)
from /opt/local/lib/ruby/gems/1.8/gems/htmldoc-0.2.1/lib/htmldoc.rb:154:in `generate’
from pdf.rb:18

I’m using:
htmldoc (0.2.1)
Rails 2.1.1
ruby 1.8.7

on a mac osx 10.5.4.

I could not google that error. It actually occurs with every htmldoc script I run.

Do you have any advice?

Thanks!
Mike

The fix was simple.
cd ~/documents/code/merb/sources/dm-more/merb_datamapper
gem clobber_package
gem package
gem install –install-dir ~/documents/code/merb/gems -f pkg/merb_datamapper-0.9.8.gem

Hope this helps someone.

If I was to need to set a role by default - would you have any tips for what to add and where? I’m having a brain freeze on it! What does this line mean:

params[:user][:role_ids] ||= []

?

Thanks

@Clint Hill: thanks Clint. good to know for any windows users using cygwin.

Just wanted to note (maybe for others) that ruby2ruby and ParseTree bomb out in Cygwin. Their dependencies on each other really screw up the install call you have above.

They will install together or separately but not while in the list as shown above. Even when the order is switched to match dependency (ParseTree first then ruby2ruby).

I have them installed but fought this a little bit and wanted to mention it.

I think it is thor merb:edge:dm_more –install

Tks,

Peter.

Getting FreeImage working was a freakin nightmare. But I thougt I’d leave a trail for those who follow.

I got it up and going decently at first, gif’s worked, but not jpegs. I eventually tracked down this, which talks about some conflict with the jpeg library:
https://bugs.launchpad.net/ubuntu/+source/freeimage/+bug/128026

If your production environment happens to be Ubuntu Gutsy like me (on slicehost) then you might find this useful:

http://pastie.org/pastes/104754

I don’t know who put it there but it saved my bacon.

FYI, there were some other things i had to do to get that working. For example, I had to change line 8 to this:
apt-get source libjpeg6b

I also had to install some tools along the way as I got errors, such as:
sudo apt-get install liburi-perl
sudo apt-get install fakeroot

Also, after running line 23 I got an error like this:

Now signing changes and any dsc files…
signfile freeimage_3.9.3-3ubuntu1.dsc Brian Armstrong
gpg: skipped “Brian Armstrong “: secret key not available
gpg: [stdin]: clearsign failed: secret key not available
debsign: gpg error occurred! Aborting….
debuild: fatal error at line 1174:
running debsign failed
debuild returned 29
Couldn’t run ‘debuild -i\.git/ -I.git’

Which was only resolved by going and reading about gpg:
http://www.quantumlab.net/pine_privacy_guard/howto_setup_gpg.html

I had to go through the steps of “gpg –gen-key” and create a passphrase with that exact name and info “Brian Armstrong “. Before line 23 would run.

I have no idea what any of this does…personally I hate anything that invovles a “make install” to get it working (mostly because it never seems to work right).

I can’t believe it’s really this hard to get this working. Anyway, thanks to ImageScience for a cool program…I know it’s not your fault FreeImage is so difficult.

Best of luck to everyone, and I really hope these things get easier over time for rails developers everywhere.

I want to copy all code from ysi_editor textarea with html so is it possible?

sudo thor
sudo: thor: command not found

You can specify a class like :class => ‘blog_post’, that shows the text editor. And without that class the textarea will not include the editor buttons.

Just follow the readme here to get it setup: http://github.com/larsklevan/yui_editor/tree/master

irb(main):001:0> require ‘rubygems’
ArgumentError: wrong number of arguments (0 for 1)
from (irb):1:in `require’

from (irb):1

I want to use tinymce but i have one problem like in my page there are so many textarea and i want to use tinymce for 2 textarea only so can you say me hows that possible?

Type this from your bash:
irb

# then once in the irb prompt type this:
require ‘rubygems’
require ‘thor’

# it should return true (=> true) for both. exit irb with ‘exit’

Then, maybe try updating your rubygems:
sudo gem update
sudo gem update –system

Then try running just plain “sudo thor” and see if you get a response.

two issues:
1. i didn’t have rake so I got it with aptitude.

2. when i type:
thor install http://github.com/jackdempsey/merb-thor/tree/master%2Fmerb.thor?raw=true –as=merb

I get:
bash: thor: command not found

(and I have thor 0.9.6)

i get this:
sudo: sake: command not found

when i do gem list it looks like sake is installed:
sake (1.0.15)

I have ubuntu 8.04 and I sake never works on my machine.
any idea?

I believe that the OS X 10.4 version comes with a patched version of sqlite 3.1.3. Perhaps I could obtain that from somewhere? I have hunted high and low on the Internet with no luck.

Any ideas welcome!!

When testing it out myself, I didn’t see much of an uptick for a rarely visited site (like 20mb).

You can try for yourself, and see what you come up with. Here’s a tutorial: http://scottmotte.com/archives/145

I would recommends it for lightly visited sites for clients and things. I believe Ben Hughes and/or a commentor agrees on this at: http://www.railsgarden.com/2008/04/12/configurating-passenger-mod_rails-on-slicehost-with-ubuntu-710/

config.gem “googlecharts”, :version => ‘1.3.4′, :lib => ‘gchart’, :source => ‘http://gems.github.com/’

Thank you, again, for your insights.

Your script worked great.

Here’s what I used adapted from your script on my mac.

require ‘rubygems’
require ’safariwatir’ # use watir gem

test_site = ‘http://www.google.com’ # set a variable
ie = Watir::Safari.new # open the IE browser
ie.goto(test_site) # load url, go to site
ie.text_field(:name, “q”).set(”pickaxe”) # load text “pickaxe” into search field named “q”
ie.button(:name, “btnG”).click # “btnG” is the name of the Search button, click it

if ie.text.include?(”Programming Ruby”)
puts “Test Passed. Found the test string: ‘Programming Ruby’.”
else
puts “Test Failed! Could not find: ‘Programming Ruby’”
end

Thank you for the mind dump.

It was all good until I tried to test watir.

I ran the following script….

# Here we see a very simple WATIR script to drive to google (testgoogle.rb) and validate a page

require ‘rubygems’
require ‘watir’ # use watir gem
test_site = ‘http://www.google.com’ # set a variable
ie = Watir::IE.new # open the IE browser
ie.goto(test_site) # load url, go to site
ie.text_field(:name, “q”).set(”pickaxe”) # load text “pickaxe” into search field named “q”
ie.button(:name, “btnG”).click # “btnG” is the name of the Search button, click it

if ie.text.include?(”Programming Ruby”)
puts “Test Passed. Found the test string: ‘Programming Ruby’.”
else
puts “Test Failed! Could not find: ‘Programming Ruby’”
end

… and got this error:

$ ruby testgoogle.rb

Any ideas on how to fix that?

Did you first uninstall the sqlite3-ruby gem via sudo gem uninstall sqlite3-ruby?

Then after doing the curl, and make, and sudo make, did you then reinstall the sqlite3-ruby gem by doing sudo gem install sqlite3?

What happens when you type ****sqlite3**** into your terminal?

For anyone interested here’s the link: https://code.adelao.it/trac/scrubyt/browser/trunk/examples?rev=2

(go ahead and trust the ssl certificate. I think it’s just self assigned)

Best of luck with your startup.

morse:/Users/Shared/software/addressbook rubyrails$ rake db:migrate
(in /Users/Shared/software/addressbook)
rake aborted!
no such file to load — sqlite3/database

This is on a Mac OS X Server box btw. I think I may have to resort to MySQL.

Therefore you can’t use the XPaths directly from FireBug in scRUBYt! (well, unless the source *really* contains a tbody tag, and it’s not inserted by FF later. So it’s incorrect to say you need to *always* remove the tbody tag, because if it’s there in the page source, Hpricot will also parse it)

The second problem: scRUBYt! guesses if an example is an XPath or not - and the regular expression telling of XPaths from non-XPaths is quite weak, and in these cases scRUBYt! thinks the example is just text and this doesnt work of course.

In these cases you should force the example type:

stuff “font[@size=n]“, example_type => :xpath

and if you do this, scRUBYt! will do an XPath matching.
Let me know if this works.

Unfortunately you are right about the documentation - it sucks It was fairly good when the very first version was released, because scRUBYt! didn’t know much at that time, but since then even some of that changed and a lot of new stuff was added, sometimes breaking backwards compatibility… and I have to agree that because of this, the docs/tutorials are basically meaningless right now (or at least would need a lot of revamping, beefing up, mashing up with all the info in the forum, filling in the gaps etc).

Unfortunately I am pretty caught up with my new startup and don’t have time for all this right now. There have been a few guys who got enthusiastic about scRUBYt!, wrote a few posts, started answering questions on the forum or even started to work on a documentation - unfortunately all these efforts ended too quick without a real result.

We even have a trac up (https://code.adelao.it/trac/scrubyt) but not enough time to edit it

Today scRUBYt! knows about 30% of the final product I am imagining right now, so even though it was and is used in production already to scrape large sites with tens of thousands of records in some cases, it’s still pretty rough around the edges.

Anyways… have fun and don’t hesitate to ask questions directly or on the forum.

Cheers,
Peter

Might want to look at the above url for slicehost

http://rails.lipsiasoft.com/wiki/lightbox seems pretty nice and does the trick for basic functionality.
