I have just set up RoR to find out for myself if this tool is stable
enough to actually be used yet.
Anyhow, I started by going to the RubyOnRails website and following the
instructions to install the platform on my Windows 2000 PC.
"Get Ruby on Rails in no time"
"We recommend Ruby 1.8.4 for use with Rails."
So... I downloaded 1.8.4 and installed:
C:\>ruby -v
ruby 1.8.4 (2006-04-14) [i386-mswin32]
Great...
Then I''m told to "gem install rails --include-dependencies"
So, I did that...
C:\>rails -v
Rails 1.1.4
Then started following the tutorial here:
http://media.rubyonrails.org/video/rails_take2_with_sound.mov
Great, this all looks really cool, let me try and do it... All goes well
until 7:20 into the demo. I do exactly the same and get this error in my
brouser:

It seems that the (:long) on the to_s does not work. I tryed to find
things about this already and it seems that there were similar problems
10 months ago (http://dev.rubyonrails.org/ticket/2344) and at the start
of the year here (http://www.ruby-forum.com/topic/52205) and it seems
that the problem still exists.
Basically, what I want to know is, is this platform really worth me
spending any more time looking into or does it need a few more years
before it will really be stable enough to be useful. (Mind you, bugs
that have been known about for 10 months and still not fixed, perhaps a
few more years would not be enough).
What are your oppinions about this?

Mark, I haven''t done the tutorial that you are talking about but it appears there is a bug in your code, you aren''t supposed to put symbols in quotes. So line #8 (exactly where the error message pointed) should be like this: <%= post.created_at.to_s(:long) %> More than likely that will fix your bug which was simply a Ruby syntax error. Given the vibrant community of intelligent people I think Rails is ready to go. Now. There will always be bugs in documentation, tutorials and code. Especially when a framework is changing as quickly as Rails does. It takes just a little more effort on the developer''s part to keep up with the changes. Welcome to Rails! I hope you enjoy your stay.

You''re watching a video that''s pretty old and was really never
meant to be a
tutoral. It''s more of an marketing ploy. This framework changes very
fast
but the pain is worth it. Everyone here who uses this professionally finds
it very much worth it. Not only because we''re more productive, but
because
it''s fun.
Also, this looks wrong:
<%= post.created_at.to_s(":long") %>
But this looks right...
<%= post.created_at.to_s(:long) %>
:long is a *symbol*, something special and unique to Ruby. It''s not
meant to
be embedding in a string.
>From my own app as proof:
event = Event.find :first
event.created_at.to_s(:long)

Good luck with your journey on the Rails.

Wow.. Guys are really freindly and supper quick... Thank you! :)
Actually that was not the bug though :(. I hit the problem initially and
tryed putting "''s in to see what would happen with "%e",
"%Y", ":long"
etc. Then forgot to take them out for my example post, to prove I still
have the problem here is a new extract after having removed the quotes:

[Rails] Re: Unable to follow basic RoR tutorial (Win32)
With respect to the framework changing... I started our rails app last year when Rails was "pre-release". I have since upgraded a few times to various releases and much to my amazement, all of my code has continued to work with one exception. The ONLY problem I have had was when I upgraded engines (to use date_box engine) and my LoginEngine broke. I simply upgraded my LoginEngine to the latest version and then everything started working properly again. Is my experience unique? I don''t feel like I have had any pain with the framework evolving and expanding. Maybe my app is so basic that it doesn''t break - but I feel that I do a lot within it. A few days ago there was a thread on this forum about RadRails which has a lot of helpful information in it for new people to Rails/RadRails. I suggest searching or looking through the archives for this weeks posts to find that article. Regards, Michael -- Posted via http://www.ruby-forum.com/.

I think your database is not returning a Time object. Try this to troubleshoot. change line #8 to: <%= post.created_at.class %> This should render out "Time" if it doesn''t, you have the wrong datatype set on that database column. Change the database column data type to "datetime" (on mysql, not sure of others) and it should work fine. The basic logic here is that if the to_s method does not take a parameter, that the object it''s called on is not a date. Though polymorphism is powerful, it can be tricky at times. -- Posted via http://www.ruby-forum.com/.

These types of exceptions, no matter how cryptic the actual error may seem, are almost always the fault of the programmer. And on the few times that the framework does indeed have a bug, its pretty simply to write a patch/plugin to fix it. Rails is used on many production sites, succesfully and stable. The only time it chokes is when I do something stupid. And each release since 1.0 has been 100% backwards compatible. -- Posted via http://www.ruby-forum.com/.
Hi Alex, Thank you for taking the time to reply. I did exactly as you described and got quite an odd response: -------- My wonderful weblog Oi Tudo bem? *NilClass* (Edit) Hello How are you? *Time* (Edit) New post ----------- * I added The *''s around the printed class. It seems the first time the template is used it said that the class is of type "NilClass"... Great, we found the bug.. but.. the second instance it says the class is a "Time" class as we expect, I check the database and sure enough it is a datetime field, and checking the value through the database view it is "0000-00-00 00:00:00" not initialized (because I added the created_at field after the first entry. So it seems that if there is data in the field it knows that it''s a datetime field, but if not, it doesn''t know the type. Is this normal?

Hey Mark, I had the same problem as you. Here''s the fix: Replace: <%= post.created_at.to_s(:long) %> With: <%= post.created_at %> Then just edit one of ur posts so that the date and time are refreshed. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
