Re: [Rails] any gems to process PowerPoint files?

Ruby on Rails

Let's say the uploaded PPT is belong to Document model, and it's pages
images are belong to DocumentPage model.

So you need to make Paperclip Processor, which you use in Document
model. Inside this Processor you need to:
1. Create tmp folders where you will perform all operations
2. Convert PPT to PDF using http://www.artofsolving.com/opensource/pyodconverter
3. Convert PDF to TIFF images using ImageMagick.
4. Process TIFF images with
Tesseract(http://code.google.com/p/tesseract-ocr/) to extract
keywords.
5. Convert TIFF to PNG
6. Create DocumentPage models passing PNG images and extracted
keywords as a parameters.
7. If all DocumentPage models are created, just go out of Processor to
let the Document model be created.

Here is the Processor
https://gist.github.com/723079
It's kinda messy and kinda belongs to my application, but you get the idea.

If it were my app, I think I'd do this differently: start a transaction
for the "what if" stuff, then either roll it back or commit it when
done.

[Rails] Re: Error creating model object using accepts_nested_attributes_for

Ruby on Rails

Thanks Frank. I finally found this post on the forum
http://www.ruby-forum.com/topic/191857 that points out what you have. It
is interesting that the form_for declaration in the view has to be
something like follows

<% form_for @modelname do |f| %>

instead of

<% form_for :modelname do |f| %>

Don't yet understand why this makes a difference but that is what makes
the difference and posts data with nested model name appended with
"attributes" as you point below.

Thanks for the feedback - very much appreciated. Past that hurdle and
onto the next one.

It's usually the model's job to validate. That's what the validates_*
methods are for.

Validation in the controller will lead to repetitive code scattered all
over the application.

Fred,

The response is correctly formed, I meant XML file, the problem looks
like it is after that, But we don´t know where..

Here I attach XML request and response... of the two API that are
linked.. the second one is the one that I said that is responding
correctly.

if it is in the public folder of your app then you just want

[Rails] Re: Checking parameters

Ruby on Rails

Thanks for the answers.

One last general question. Where do you validate your parameters
fetched by "params" that should be passed to models? Do you check them
right away in the controller and give them cleaned up to the model, or
do you just provide them as they are (maybe just put them in single
variables) and let the model check them?

=>the iframe says, if i have Javascript:
No route matches "/firmas/public/6465_p_61_620_15674.pdf"

=>and, if i haven't:
No route matches "/mostrar_pdf/public/6465_p_61_620_15674.pdf"

[Rails] Rails 2.3.8 Action Caching without layout (ajax and non-ajax requests)

Ruby on Rails

Hi there,

I'm using Action Caching with Rails 2.3.8 on Heroku with Memcached
(via Dalli Gem).

Without the layout parameter Action Caching works fine. However, as
soon as I add layout => false I get problems: Normal non-ajax requests
are cached fine, without the layout, as expected. But ajax requests
are not properly cached: I get cache misses all the time. Then, when I
log in to my app neither normal, nor ajax requests are cached at all.

I also tried to set :layout => Proc.new { |c| c.request.xhr? }
When I do that ajax and normal requests are properly cached (no matter
if logged out or logged in)
but normal requests also cache the layout. Seems odd to me as normal
requests should have :layout => false.
I'm trying to debug this for hours now, but I haven't got a clue
what's going on so far. What especially confuses me
is that the logged in state of my app apparently has an influence on
the caching behaviour.

Here is my full caching call (for the case of layout => false):

[code]caches_action :index, :layout => false,
:cache_path => Proc.new { |c|
c.params.clone.delete_if { |k,v| ['authenticity_token'].include?
(k) }.merge(:xhr => c.request.xhr? ? 't' : 'f') }[/code]

I'd greatly appreciate any help on this!

I'm having trouble seeing where you're even trying to explain what you
have, and what you want....

Does this give what you're after? :
<%= @sp_references.map(&:all_references).flatten.map(&:reference).uniq.delete_if{|ref|
ref=~ /emend$/i}.join("<br/>") %>

To be honest, I'm just stabbing in the dark, because you've not
explained anything about what these objects are made of or what actual

I need the results have to print without duplicates. This gives the results with duplicates.

<% @sp_references.each do |sp_ref| %>

<%= sp_ref.all_references.map(&:reference).delete_if{|ref| ref=~ /emend$/i}.join("<br/>") %>

and

<% @sp_references.each do |sp_ref| %>

<%= sp_ref.all_references.map(&:reference).uniq.delete_if{|ref| ref=~ /emend$/i}.join("<br/>") %>
<% end %>

presents same results with duplicates. Please about your suggestion.

[Rails] Re: Dependency Problem

Ruby on Rails

Do you remember the version of the gem(s) you had before you updated
them? There is a way to install specific gem versions by adding the
version at the end of the install command. Something like this:

gem install rails -v=2.3.5 # This would install Rails 2.3.5

You can also check the dependencies of the other installed gems to try
to figure out the version you might be missing. Check the
documentation at http://docs.rubygems.org/read/chapter/10#page78

Right... also, when you say your pdf is blank --- does the file actually open or is it empty? I had a situation where I was getting empty files, which of course would not open. I'll try to remember what the solution was if you let me know what your situation is.

This data doesn't look like what the nested_attributes stuff looks
like - I would expected it to be more like
'uploaded_attachments_attributes' => {{'0' => {'name' => 'Test 2'}}

What does your form look like?

yes..

in this case method(".create()") first creates record in db table and
then it provides you hash with table's all attributes and values which

Hi,

Friend when you create any "new" object usign UserSkill or any class
class
which is associated with ActiveRecords.. then it auto create one hash
with all attributes of user_skills(or any relevant) table.. this is due
to ORM feature of the Rails..

Second thing, that all values seems to nil in that hash.. this is
because it provide you blank hash.. to do process or to assign required
values to
the attributes..

nil is just because as we know ruby has greate feature of NilClass to
avoid exceptions on nil values..

I dont know is this answer of your question or not.

Good luck ;)

I was upgrading from rails 3.0.0 to 3.0.3 and starting "rails server"
complained about needing i18n 0.4.1 but 0.5.0 being active so I
reinstalled all rubies with rvm, removed all cached gems, reinstalled
rails and removed i18n 0.5.0 to leave only 0.4.1 there and it finally
worked.

Used Debian squeeze 64 bit, rvm, ruby 1.9.2-head, rails 3.0.3

Since no one else has responded, and I don't know how it relates to
the error you are seeing, but I wonder whether this should be an array
of uploaded_attachments rather than a single instance.

Whether that is the issue or not, it might be worth removing the
attachements spec from the form initially just to check that you can
create a new object without the nested objects.

Do you know how to use reby-debug to break into your code and inspect
data and follow flow. You could break in before the offending line to
double check the data at that point. See the Rails Guide on debugging
if you are not familiar with this.

Hello,

you can do these kind of things from console. Do you have SSH access

First install the Haml gam:
gem install haml

Second write it to your Gemfile in your app's root folder:
gem 'haml'

Then try 'bundle install' in terminal.

If you have an error message its easier to go further. Please write it
here with your OS, gem list, versions you use.

Check these for Haml:

I think don't be afraid, just try it out! On your cpanel you can

You can also make a server on your machine, you will reach it as

Also you can ask your hosting's support.

After you tried to make it work, and something has error message -
it's much easier to help you, since we know what is your problem.

Well the error message is NoMethodError, Model UserSession does not
respond to t_login which is saying the UserSession does not have a
method t_login, which suggests to me that the name is the problem.
Have you done something somewhere else in your code to tell Authlogic
to expect the different names?

It is easy enough to see if this is the problem here, just change
those few lines of code and see if that error goes away.

Re: [Rails] Re: referring to params in other controller

Ruby on Rails

basically you got two possibilities: 1. write the value into a session-variable   session[:object] = "some string or value"  2. pass your value as a parameter to some action and read params in your controller: view:   <%=  link_to "my_action" :controller => :bla, :action => :my_action, :object => "some string or value" %>

controller:   def my_action     puts params[:wtf]   end

Sure. I have a page in (view\controller x) with an input field.
Submitting the form displays the value of the input field on this same
page.

There is a link on this page that connects to another page in a
different view/controller (view\controller y). I want to use the param
(input field value) as a conditon in a 'find' in the controller y. But I
am not yielding results. It's like the param is empty. I hope this makes
it a little clearer
