Example application not working


#1

Hi,

I am trying to create the sample application as mentioned at the
following link:
http://www.onlamp.com/pub/a/onlamp/2005/01/20/rails.html?page=2

But the example doesnt seem to work.
I am following the exact steps as mentioned on the above page and type
the following at the command line(as mentioned in the example)
ruby script\generate controller MyTest

Then after doing this I go to the browser and type the following in the
address window:
http://127.0.0.1:3000/MyTest/

But the response that I get is:

“We’re sorry, but something went wrong.
We’ve been notified about this issue and we’ll take a look at it
shortly.”

Plz note that when i do “http://127.0.0.1:3000/” a web page is opening
correctly. but not when i do “http://127.0.0.1:3000/MyTest/

What could be the possible reason and whats the fix. I am a beginner and
started learning RoR today itself with this first example.
Any help will be greatly appreciated.

Thanks & Regards,
Kamal

These days you would need to go to http://127.0.0.1:3000/my_test

You’re following a tutorial that is over 4 years old. A lot has
changed. A good starting place would be the guides on
guides.rubyonrails.org

Fred,
I tried with “ttp://127.0.0.1:3000/my_test” as well but it doesnt make
any difference. Is there any other fix/cause of this problem.
I will follow the new tutorials that you have suggested.
Thanks for your suggestion and response.

Regards,
Kamal

Hi icemag,

The output is the following in the browser window:

"We’re sorry, but something went wrong.

We’ve been notified about this issue and we’ll take a look at it
shortly."

Any pointers.

Thanks & Regards,
Kamal

Icemag,

I am sorry, you asked for output on console and not in the browser.
Infact when I do “http://127.0.0.1:3000/my_test”, i dont see any output
on the console. But when i refresh the page in the browser once again I
see the following output(repeated twice, probably for the prev trial
too) on the console(where the server is running):

You’re missing the sqlite3 gem. Try ‘gem install sqlite3’.

However, as Frederick C. pointed out, you’re following a very old
tutorial. I’d suggest checking out
http://guides.rails.info/getting_started.html

Good luck!

Thanks Bjørn Arild Mæland…
It worked.
Yes…I have started with
http://guides.rails.info/getting_started.html” itself as suggested by
Fred and you…
