Hello world

Thufir · June 20, 2007, 10:05am

I’ve done these steps before, but am retracing my steps. Now, it
generates an error and I’m not sure why. Navigating to <http://
localhost:3000/hello> gives:

"Action Controller: Exception caught

Unknown action

No action responded to index"

Which is a bit frustrating because I’ve had it working in the past

(the bash script prints out a copy of itself, if that’s unclear)

Hmm. When I did the following, and went to <http://localhost:3000/
hello> I did see “hello world” as I wanted. However, I can’t figure
out why it works when I type in the commands by hand but not from the
bash script. I like the repeatability of the bash script, so want to
fix it. I’m looking it over, but any input would be appreciated!

Oh, this is based on the tutorial at <The collected ramblings of Jakob Skjerning | mentalized.net

Dear Thufir,

In your first script you were echoing “hello world” to index.html.

It needs to be index.rhtml.

Additionally, your controller needs an index action in it.

But I can’t figure out why you are doing this in SUCH a hard way!

Try this (with SQLite3 installed as a prerequisite)

rails text -d sqlite3
cd text
./script/generate model HelloWorld title:string message:text
rake db:migrate
./script/generate scaffold HelloWorld
./script/server

And then open your web browser and point to
http://localhost:3001/hello_worlds/

Regards

Mikel

Boy, it took me about an hour to get it working. I probably looked at
that line twenty times and my eye just went right over .html and said
“fine”. c’est la vie.

Additionally, your controller needs an index action in it.

english please
what does that mean more concretely?

But I can’t figure out why you are doing this in SUCH a hard way!

I’m recovering ground with a script because I need it to be repeatable
because I’ve run into a wall further down the line. This is a
foundation.

The legacy database is MySQL, I have MySQL setup, I like the
myPHPAdmin GUI, and, again, the legacy database is using MySQL.

The end goal is to get this working with <Google Code Archive - Long-term storage for Google Code Project Hosting.
feed-on-feeds/

which is, ironically, a PHP application.

The next step is that I have a database “Dummy” with table “Dummy”
which I would like listed. I did this before but forgot. Hence, the
bash scripts.

Then, I’ll move onto the legacy database, some day…

Get these books (PDF or paper)

Four Days on Rails
and
Agile Web D. with Rails

Read them, both books are pretty easy to follow, if you have worked with
PHP, Rails shouldn’t be that difficult. For me it was simply
terminology. Once I learned how models and controllers worked,
everything “just worked”

I have seen torrents on tpb and mininova, tho your mileage may vary.

Somewhere along the line, I think a .rhtml morphed to a .html, but
other than that, I pretty much copied the first script to the second
one and it worked…dunno why.
