Generating GUIDs in Ruby
(11 answers)
Closed 10 years ago.
I am looking for a list of UUID gems for Ruby on Rails, could someone please recommend a couple to me, preferably ones that are not so complicated that I wouldn't be able to understand them easily.
The Ruby Toolbox is a nice place to start your search.
I would strongly recommend you to use UUID Tools
A brief of what they offer:
UUIDTools was designed to be a simple library for generating any of
the various types of UUIDs. It conforms to RFC 4122 whenever possible.
I have been using it for different projects and I haven't had any problems. Also, the documentation is pretty good. Check this out for more reference UUID Tools Reference

Cannot find origin object in Rails project

RoR noob here.
I need to decorate some controllers, helpers, models etc from Solidus. Solidus is divided in solidus_core, solidus_backend, solidus_frontend, solidus_api... finding what I need is a pain in the ass. I basically open the one that seems the most obvious for what I'm looking for but often I end up opening all of them and doing a global search. Is there an easier way?
Also when I'm looking at a view, sometimes I see something that looks like a method call. How can I know if it comes from a helper or the controller? How can I know if it comes instead from a gem? Or from another related package that is part of a gem?
I find it so confusing, I never know where things are and where to look for them. Am I missing something?
Because of the duck typed nature of Ruby, and the heavy use of meta programming in rails, this type of problem is not easily solved.
Two pieces of advice:
Use an IDE such as RubyMine or VS Code to jump to declaration - you can control click to jump to the definition of methods. This doesn't always work, but it does most of the time, as long as the method has a unique name.
Use an IDE that has good search functionality. I personally use VIM because I can easily extend the search component to use command line linux, making it very fast to scan very large projects quickly.

are extensions bad for performance in swift?
(2 answers)
Closed 3 years ago.
So i have been somewhat thwarted from using extension in my new work place and the reason is that it slows the app down?
Is it true? I cant seem to find any article that verifies this
Cuz i am so used to using extensions to wrap things of similar functionalities, same protocol together.
Extensions do not affect application performance, because in general it's gets compiled into the same machine code, especially when using Whole-Module-Optimization.
However huge number of extensions might affect your app's compile times. Take a look at this benchmark.

Ruby obfuscator [duplicate]

Closed 9 years ago.
were developing a ruby on rails application for a customer who wants the software to run on his server.
So, we want to have a mechanism that enables us to say that the customer may only use the software for a certain time.
Is there a way to "compile" the software that prevents the customer from tampering with the code?
Cheers,
Henning
I'm afraid this is far from trivial - ruby is script based, and there is no way to stop others from 'tampering' with your code.
There was a discussion about this on https://www.ruby-forum.com/topic/60047, and here is one possible suggestion:
One solution may be to compile a small app that takes an MD5, SHA, or
some other checksum of the ruby code and only executes it if it is in
an internal hash of allowed files. You could have user-based hashes of
allowed files based on who is logged in. Of course you will have to
rebuild this app every time you change the ruby code but that could be
automated. But a user could run the ruby code directly unless you
build in some dependency to the compiled app. If they can see the
source code, they can copy it, tamper with it, and run it.

I am new in ruby dont know the strength about ruby. I have some idea about ruby on rails for building web application so now i want to know about area where we can use ruby like is ruby only useful for web based application or we can write stand alone application also. like C and C++ can we write hardware level code or not. I tried to find my answer on google but did not get it and its my humble request give me guideline or some useful link to explore my knowledge and please dont close this question i am not interested in reputation i am just interested in my answer so please co-prate with me and my question .
Want a full over view and aspect of ruby its all about my future.
Ruby is a programming language and Rails is a web framework for building web applications.
If you are looking for a framework which would enable you to quickly build a web application, then Ruby on Rails is for you. Through the concept of convention over configuration, configuration is only used where necessary, and so, simple applications would no longer require lines and lines of XML.
Ruby programming language combines ideas of the dynamic scripting languages and a strong framework which is object-oriented. Additionally, Ruby on Rails leverages the extensive support of Ruby for metaprogramming, where it derives its elegance as well as its ease of development.
It makes use of code generation features, which makes it easier to start complete applications and promote agile programming techniques. Rails is also unique in the field of web application in the sense that it makes use of two key design features which are DRY or “Don’t Repeat Yourself” and CoC or “Convention over Configuration”.
Ruby is truly object oriented, in the sense that everything is object in ruby. You can built stand alone applications using Ruby.
You can Learn more of Ruby and Rails here.
Ruby is a scripting language so no it's probably not suitable for "hardware level" code. It's a higher level language than c/c++ and probably the only languages it makes sense to compare it to are perl, python and php.
Of those three I would say it's biggest strength against them is the ruby community. A consensus always forms behind good projects and competing projects either disappear or merge. It's no surprise that ruby is the number 2 language on github (let's face it, everybody has to use javascript at some point.) If you compare a common library like nokogiri to python's offerings you get a community that's split in half between beautiful soup and lxml. For php it's even more drastic. Maybe 8 competing libraries vie for the same space (and every php programmer a cowboy who thinks he can do it better).
As in above answer by Mithun, now you got the short brief idea about what ruby is ? and what Rails is ? For more better short description about Ruby on Rails(RoR) is available on wiki page here Wiki page for Ruby on Rails
You can get everything about ruby on rails on this documentation Learn all about Ruby on Rails Development.
For beginners to give startup you can start up with Ruby on Rails tutorials.
In case You are a Experienced developer in other language then you can learn a Basic Ruby language form Learn Ruby Quickly another good learning tutoral is Learn Ruby. Once you are done with basic Ruby then you can start with Rails framework. Rest of the things you can learn while developing application. Best documentation of Rails Framework is Ruby on Rails Guide. You can find everything in one place.
The best thing of this documentation is, it updates all the time when some new releases come.
I'm looking for a good wiki platform to work with RoR, I know mediawiki is great but its in PHP and I'd rather keep my code base in the same language if possible.
DHH (I think) wrote a simple wiki in Ruby several years ago called Instiki. I haven't used it in a while, but I'm sure the code is out there somewhere.
If you want an active project, there's something called Decko, which is a wiki in Ruby, but an unusual (and apparently successful) take on how to do a wiki. I've not used it, but all my poking at it suggests it's a very well-thought-out and useful approach. Find it at https://decko.org/
Here are list of wiki software written in Ruby and in other languages as well.
http://en.wikipedia.org/wiki/List_of_wiki_software#Ruby-based
Try the font of gem-ishness, ruby-toolbox.com
https://www.ruby-toolbox.com/categories/wiki_apps
I note the top 3 are all git-baseed, rather than database based, at time of writing.
I've used none, myself yet. So I guess we use number of download be a guide?
