A friend of mine asked me if I was aware of Ruby on Rails ... and frankly I have heard a lot about it but know practically nothing about it. Any help will be much appreciated.
I want to be able to edit and delete resources myself, but not allow users of the application to do so.
Is there an easy way of doing this in Rails?
An incomplete solution would be just to remove the "delete" and "edit" buttons from the index view, but that doesn't disable their ability to do so via direct HTTP requests.

I have a simple Ruby on Rails form which includes an authenticity_token. Unfortunatly, I missed that when you page cache this page then the Authenticity Token becomes invalid. I'm glad I figured it out however.
How do you solve caching in such a case?
Hai
I need to retain the Form data submitted in one view to be used in another view.
I'll be using POST method to submit the data. Is there anyway I can retrieve data from the POST method in Ruby, like in PHP I would use $title=$_POST["title"].

Thanks and Cheers !
How can I declare a method with keyword arguments just like rails do. some examples may be

Does anyone know if it would be possible to dynamically load gems from compiled code? Or compile the gems and link them in? Is this planned? Or how compiled code will be able to make use of gems in general.

I have a binary files which needs to be sent as a string to a third-party web-service. Turns out it requires that it needs to be base64 encoded.
In ruby I use the following:
body = body << IO.read("#{@postalcard.postalimage.path}")
body is a strong which conists of a bunch of strings as parameters.
So...how do I base64 encode it into this string?
Thanks.
Can't seem to find how to check if an object is a boolean easily. Is there something like this in Ruby?
true.is_a?(Boolean)
false.is_a?(Boolean)
Right now I'm doing this and would like to shorten it:
some_var = rand(1) == 1 ? true : false
(some_var.is_a?(TrueClass) || some_var.is_a?(FalseClass))
In a simple Ruby example, I'm getting an error that does not occur in irb.
name = "Joe"
def say_hi
"\"Hi there!\" said #{self}"
end
response = name.say_hi
puts response
This code should return, "Hi there!" said Joe.
It works perfectly fine in irb. However, when I attempt to put the same code in a file and run the file, I get this error:
say_hi.rb:8:in `<main>': private method `say_hi' called for "Joe":String (NoMethodError)
Any suggestion about why this happens?
How can I verify the certificates of a site like https://processing.ukash.com/ in ruby with net/http?
https = Net::HTTP.new('processing.ukash.com', 443)
https.use_ssl = true
https.verify_mode = OpenSSL::SSL::VERIFY_NONE
Works so far, but how do I verify that it's the right cert now? I saved the certificate from within firefox, but the resulting .pem file has many certificates in it and net/http doesn't seem to like it.

The post office actually publishes a list of commonly used street suffixes in addresses:
http://www.usps.com/ncsc/lookups/abbr_suffix.txt
I want to take this list and make a ruby function that takes a string, takes the last word ("183 main strt".split[' '].last) and if it matches any of the commonly used street suffixes ("strt"), replace it with the official Postal Service Standard Suffix ("st").
Is there a better way to approach this than a massive str.sub.sub.sub.sub.sub?
How do I include the 'autofocus' attribute on an HTML5 form using the text_field form helper in ruby?

Hi guy,
In ruby ActiveRecord doesn't provide dynamic binding for update and insert sqls, of course i can use raw sql, but that need maintain connection, so i want to know if there is simpler way to escape update or insert sql before executing like code below:
ActiveRecord::Base.connection.insert(sql)
i think i can write code by gsub, but i know if there has been a ready method to do it.
thank you very much, and Merry Christmas for you all.
My company has data messages (json) stored in gzipped files on Amazon S3. I want to use Ruby to iterate through the files and do some analytics. I started to use the 'aws/s3' gem, and get get each file as an object:
#<AWS::S3::S3Object:0x4xxx4760 '/my.company.archive/data/msg/20131030093336.json.gz'>
But once I have this object, I do not know how to unzip it or even access the data inside of it.
Is there a better way to write this Expando class? The way it is written does not work.
I'm using Ruby 1.8.7
starting code quoted from https://gist.github.com/300462/3fdf51800768f2c7089a53726384350c890bc7c3
class Expando
def method_missing(method_id, *arguments)
if match = method_id.id2name.match(/(\w*)(\s*)(=)(\s*)(\.*)/)
puts match[1].to_sym # think this was supposed to be commented
self.class.class_eval{ attr_accessor match[1].to_sym }
instance_variable_set("#{match[1]}", match[5])
else
super.method_missing(method_id, *arguments)
end
end
end
person = Expando.new
person.name = "Michael"
person.surname = "Erasmus"
person.age = 29
