The last is misleading. You have created a constant that points to an
Hash object. However, the Hash object itself is not frozen. The values
pointed to by the keys are not constant or frozen. You can add new
keys to the Hash, change values, etc. But if you try to set Const to
something else (any other object) it will again show the warning.
irb(main):025:0> Const={a: 'a'}
{:a=>"a"}
irb(main):026:0> Const[:a] = 'b'
"b"

Re: [Rails] Re: Change 'nil' using literal notation?
Jordan Bedwell is correct. Ruby's constants are /meant/ to be not changed, but
you can define a constant and change its value later. Ruby will produce a
warning 'already initialized constant'
Also note that your constant's internal representation can be changed without
triggering the warning.

[Rails] Descent RoR shared hosting
Hi everyone. I was in the market for wordpress host today and i thought while i was at it why not get a hosting provider that can support RoR too. I just about to begin to try to learn rails & ruby. I'm a .net developer. It won't be any site with much load but of course id like to pick a hoster that kept ruby & rails somewhat current (without me having to do it manually) and i don't want to have to fight to deploy RoR projects. FYI I'll just be using cheap shared hosting and not a VPS. My site won't get enough traffic for the higher end hosting. I'm currently looking at Host Gator & BlueHost. Any recommendations would be apprciated. thanks.. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

As an aside, you do realize that naming your variable "Hash_Name" makes
it a constant right?
Should be:
hash_name = Hash.new("Anything other than nil!")
If you really intended to make that new hash a constant then the
convention is:
HASH_NAME = Hash.new("Anything other than nil!")

[Rails] What would be the best way to handle this situation?
Hi All, I'm trying to work out an issue and a bit stuck on the best way to handle this, so I'm hoping someone can give me some ideas to try. I have a form that contains some info about a particular job. Part of this form has some address info that once saved we gather some Geo Location info so we can plot the distance. We had an issue where the Geo API was down and therefore we couldn't get the distance in miles from the base office to a customers location for plotting on a map. I was asked to raise an error and bring the user back to the form to manually add in the distance if the API is not responding correctly. Pretty straight forward. The issue I am having is that I have a before_save method in the Job Model that runs this geo location code. If the API is having issues I Raise an error and handle it in the controller So the Model has before_save :geolocation_address def geolocation_address geo = APICall errors.add(:base, "Geo Location Failed" ) if !geo.success raise "Error" if !geo.success end Then in my controllers update action I have @job = Job.find(params[:id]) if @job.update_attributes(params[:job]) flash[:notice] = "Successfully updated job." return if has_session_return_to? redirect_to @job.contact else render :action => 'edit' end rescue render :action => 'edit' This brings the user back to the form to manually edit which is what I want. But the problem is that I'm always going to go back into the rescue block as long as the Geo location fails. Should I pull that before_save out and manually call the geolocation_address in the controller then when I hit the rescue block pass a variable so I know not to call it again when the user updates the form again, or does someone have a better solution?

[Rails] Re: storing values in session variable vs instance variable
instance variables are alive as long as the object instance is alive. My question then would be from one http request to the next does the same controller instance remain alive? If so, then there's no need for sessions at all. Right?

The honest answer is "it depends". Do you need the multi-user goodies of Refinery, providing you a full suite of editing and publishing controls? Do you need to manipulate a site "tree" and place content in a hierarchy? If your needs are simple, you might be best served by writing something yourself. It will be just enough to do what you need, and you'll know where the bodies are buried. But if an honest assessment of your needs turns up some of the things that an existing solution does well, you may as well just use it and learn what it can do. You may end up adding features -- for free -- that you didn't know you needed.

RE: [Rails] Using scaffolding
Restarting the server didn't fix the problem, I believe I was in the correct directory but that maybe was the problem. I've since closed the terminal down and it's now working. This is certainly the fastest setup I've ever experienced in getting a framework up and running. Hopefully today's progress will be good too!

[Rails] Re: Learning Rails - Advice for development environment
Hi Michael, I think the problem may be with the hardware being too new. Some lap tops have good comparability with mainstream linux distros. I had better success with older hardware and although they run slow under windows (which is by design by M$) they run quite fast under linux. For example Lubuntu 12.04 installs without problem on a Lenovo 3000 N100. With rvm and RubyMine I can run multiple versions of ruby and rails.

[Rails] CMS functions for a Rails web application
Hi, I'm a newbie to Ruby on Rails, but I'm very attracted to this awesome web technology. The only thing I'm wondering about, is how you can add CMS-like functionality to your Rails website. Do you implement the CMS functions yourself, using Ruby Gems, or do you pick a Rails CMS like Refenery CMS, Locomotive CMS etc ... I'm especially interested in a very lightweight CMS, and I'm wondering what's the best strategy: just implement the CMS functions myself or use a Rails CMS solution like Refinery CMS, Locomotive CMS, etc ...

[Rails] Re: Learning Rails - Advice for development environment
Hi Michael, I'm kind of in the same situation as Fai. I'm a .NET developer doing ASP.NET. But currently I started doing RoR development. For that purpose I bought a Mac. I understood that lot's of RoR use Textmate ( http://macromates.com/ ) as IDE. Texmate is only available for Mac. Another great editor is SublimeText 2 ( http://www.sublimetext.com/2 ). SublimeText2 is available for Mac and PC. I also heard a lot of praise about RubyMine by JetBrains ( http://www.jetbrains.com/ruby/) But the thing I like about RoR is just that it's less tool dependent like .NET development which relies heavily on Visual Studio and Sql Server. One can develop a Rails app by just using the terminal and an editor. hope this helps, Anthony Op maandag 18 maart 2013 20:46:31 UTC+1 schreef Michael Armistead het volgende: > > Hello, > > I have been learning Rails for several weeks now.

[Rails] Re: Rails 4.0 Example app
Thank you for the suggestion, yes of course I would have given up years ago without RBs fantastically clear material. However edit multiple does not work on multi-level nested attributes. Yet edit a single multi-level nested attribute (using update_attributes) works fine. My main point is that of newcomer accessibility. TDD may make a development more agile but there is nothing better than an example app that exercises all the simple/minimum/core functionality and use-cases. Just how long do you think it would take a true expert involved in edge rails development to write a small app ? I suspect that it does'nt exist because it is too hard to do. Another point is that an example app is like a picture being worth a thousand words. It proceeds the documentation lag and displays a best practice approach that is clearly comprehensible by a much broader ability level. I would gladly write one and give it back to the community if I could get it all to work and if I was sure that my approach was in line with the current version of rails best practice. An example app should execute without error and be a minimum requirement before a new release is issued. This is another example where TDD has pushed out verifying the basic use-case requirements. Sorry if this sounds like a rant but I am almost at the end of my tether after giving up on rails 2.x, starting again on 3, and again on 3.2 and now on 4.0.0.beta1. Rails is becoming so agile that you are lucky to complete an application before the next version is released. Just one last time - can anyone knock out a simple app displaying core use-cases I have highlighted ?

[Rails] Re: Learning Rails - Advice for development environment
I am using a Mac so I do not have you problems. Is you laptop certified for a specific distro of Linux. Do you know that Dell and may be HP have laptops certified for Ubuntu and Redhat? I personally would try to use Linux, bash, git, apt-get, more performance. I would try to fix Linux issues. You could develop in Windows, Ruby works on it. Vagrant is good, you can just run 'ssh vagrant' and call tests and guard from you windows shell. The problem is that Windows shell is rubbish and you have to use putty because Windows does not have ssh. I would just avoid to use Windows entirely, it is too limiting. I would try to fix LInux issues on the laptop or buy another laptop, seriously.

Have you restarted the server since you made the change? It is not necessary to restart when changing model/view/controller files but if any configuration files (such as routes.rb) are changed then it is necessary to restart it. Othewise, did you try running rake routes to show you the routes available, as suggested? You may not yet be able to fully understand the output but it is worth following the suggestion anyway. Have a look at config/routes.rb.

[Rails] Using scaffolding
Hi all, I've been following this online book: http://ruby.railstutorial.org/chapters/a-demo-app#sec-modeling_demo_users I ran the commands: rails generate scaffold User name:string email:string bundle exec rake db:migrate As I understand it I should be able to go to the following URL and it should display a list of users: http://localhost:3000/users However I get this error: "Routing Error No route matches [GET] "/users" Try running rake routes for more information on available routes." In the first chapter another application was created, could it be that the rails server is serving the first application instead of the one from the second chapter of the book? Anyone any idea how to fix this issue? Thanks in advance. G -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I could add PassengerDefaultUser apache # (or whichever user you like except root) to the virtual host block of the apache conf. I just tested this, and it works. But there is a more elegant way. All the necessary information is here: http://www.modrails.com/documentation/Users%20guide%20Apache.html#user_switching In essence, you just need to change the owner of config/environment.rb.
