Rails - Feb 2006 - Howto work with a page not generated by the scaffold ?

I am a newbie Ruby and RoR user. In my tests using the turorials that 
I found over the web, everthing is working fine and I am very impressed 
about RoR framework.

 As I am a Delphi developer, without any web development experience, 
There is some thing hard to understando and I didn''t find a tutorial 
about this.


 I wonder how to create a non-scaffold page ? I have customers, products 
and orders for example, and I want to create a page to view the orders 
between two dates. So, I need a page that will ask for initial and final 
date, I will select the records matching this criteria in the orders 
date and joining this 3 tables?



Thanks in advance.

hi all,
I''m reading the Agile WebDevelopment with Ruby on Rails but I obtain an
error for the code at page 111.
This is the error :
SyntaxError in Admin#ship
Showing app/views/admin/ship.rhtml where line #8 raised:

compile error
./script/../config/../app/views/admin/ship.rhtml:8: syntax error
_erbout.concat(( end _form_tag ).to_s); _erbout.concat "\n"
                    ^
Extracted source (around line #8):

5: </table>
6: <br />
7: <input type="submit" value=" INVIA ITEM CHEKATI "
/>
8: <%= end _form_tag %>
9:
10:

Trace of template inclusion: /app/views/admin/ship.rhtml

RAILS_ROOT: ./script/../config/..

and this is the code :

<h1>Ordini da spedire</h1>
<%= form_tag(:action => "ship") %>
<table>
<%= render(:partial => "order_line", :collection =>
@pending_orders) %>
</table>
<br />
<input type="submit" value=" INVIA ITEM CHEKATI " />
<%= end _form_tag %>

What''s wrong with it ??

thanks

marco

  Thank you oo00oo to answer my post.

  This is a great book, I have it.

  Maybe I missunderstood something.. I will take a look on it again.

  Anyway, Could someone give me the basics steps to create a page for 
searching records in a join SQL ? I am not asking for a sample code.

  Thank you

find method is powerfull but if you need to do complex query use
find_by_sql

I don''t want to sound rude, but the Agile book answers your questions  
virtually in the first chapter, you really should look at it again. I  
suggest you not worry about the join table stuff until you at least feel  
comfortable writing your own non-scaffold code.

There are also plenty of other tutorials about Rails that take you from  
scaffolding pages to custom pages. The "4 Days on Rails" tutorial is  
very good, although I don''t know if it''s been updated
recently. http://
rails.homelinux.org/ Curt Hibbs'' tutorials are also very good and teach
you how to go beyond scaffolding. http://www.onlamp.com/pub/a/onlamp/

   Andrew,

   Thanks very much for your reply,  you didn''t sound rude. I will 
really start from the "beginning" of the Agile book.

Jose, I''m a java programmer working at a shop full of delphi
programmers and I have
watched a couple of them transition to java web apps. One thing that I noticed
is that,
when one is learning a new language and a new framework and html/css/http all at
the same
time, it''s very easy for stuff to get jumbled together... It can be
hard to distinguish
what the language/framework are doing for you vs. the basic standard web stuff.

So, you might want to spend a little time just reading through some tutorials on
xhtml and
css and how http post/get requests work. There''s lots of this stuff on
the web! w3schools
is a pretty decent site full of tutorials:

http://www.w3schools.com/

just my 2 cents...

I too was trying to figure out such things.

I need a page that will ask for initial and final
date,

this would be a form page, so it would be a view. It would
go in the view folder. You could have an action getdates
det getdates
end
in controller which automatically will call getdates.rhtml
in the view folder.

You will get the info from this page in the params. Look up
render to look at the param hash.

The controller can then select all the data, and go to
another view page, show.rhtml.

You don''t need to use scaffold at all.

Here is what I found
http://wrath.rubyonrails.org/pipermail/rails/2006-February/016082.html

I also found the following tutorial which is more about
understanding
http://www.troubleshooters.com/codecorn/ruby/rails/rapidlearning_rails.htm

I will be happy to help if I can, I only have a couple weeks
on this myself.

Hey Anne !  Thanks for the links !
I think after a while, you don''t use scaffold at all... at least I
don''t
anymore.
You just start building your application page by page, action by action,
component by component... etc.
I think scaffold is just a "ooooooo look what rails can do" type thing
that
get''s people started.

I think... or I may be missing an amazing feature and I''m wasting a lot
of
time... but, I don''t think so :)

Yap, and I have become allergic to the word scaffold and to that attitude, 
and I prefer to ignore politly anyone suggesting that since there is 
scaffold, I should use it. 

Rails is not for the true beginner. There is a lot of learning to do just to 
get to the first chapter of agile rails. some pros don''t understand
that.

Now that I am starting to understand, I will certainly never use scaffold, 
symbol a certain humiliation: How hard it was to figure out just one of 
the lines of that oh so elegant program!

Well, there''s no harm in using the scaffold generator to put the
absolute
basics in place before fleshing them out yourself.  I still use them, because 
it''s useful for getting stuff up and running as quick as possible.

Soon though, I''m planning to develop my own customised engines to
rapidly
implement the kind of stuff I need on almost every website - news sections, 
link pages, standard contact forms and so on.  Might as well practise DRY 
between projects, as well as in them...  :-)
