Content-Type: text/plain; charset=US-ASCII; delsp=yes; format=flowed
I am only 3 days into rails, so please excuse the stupid question.
I am trying to access my database named Movies. I am using a table
named movie. I would like to pull the table entry with field
vname=rawr, and then take this entry's field vpic, and use that vpic
(assume its a url to an image) to display an image.
To begin with, I am having problems with displaying an image with
html + ruby. In my index.rhtml I have two lines:
<% @pic = 'http://www.showfly.net/img/1.jpg' %>
<img src='<% @pic %>' width="50" height="75"></img>
And it doesn't display the image. What did I do wrong? How do I
make the @pic be the url that i did a search for in my database?
Thank you,
Ben

Not really our realm but if you just enclose the input element within <form>
tags and specify the action and provide a way to submit the form, it will be
sent along with the regular POST data.

Hi, I needing to modify the control.js file and am confused about what the
purpose of the getToken function is. I read the docs section below and still
don't understand why it doesn't just access the form.value directly.
Docs say:
This method should get the text for which to provide autocompletion by
invoking this.getToken(), NOT by directly accessing this.element.value. This
is to allow incremental tokenized autocompletion.
Does anyone understand the getToken function??
Thanks!

AFAIK it's because some autocompletion fields might take multiple
values and be delimited by characters like a comma or space. The get
token method allows you to get the last keyword/tag the user is
entering and instead of the whole value.

Ah, I see. Looking at the code, what you said makes since. I guess that
would be for typing in "tags" or something like that.
Thanks

I think your <img src='<% @pic %>' width="50" height="75"></img> is wrong
you can writen it like this : <img src='<%= @pic %>' width="50"
height="75"></img>
<%=%> evaluate the ruby expression., this can return result of the
expression.
<%%> ddeclare ruby expression or statement.

Andrzej,
I have been using the Yahoo! UI connection and drag and drop libraries
a bit instead of Prototype.js
Partly this is because I had read so many warning about the quality of
the Prototype.js library. Partly because I don't like the enumerable
stuff in Prototype.js. I think it makes for ugly JavaScript. Partly
because I don't really like seeing JavaScript hidden under Ruby
wrappers in my code. Yes JavaScript is weird but if I want to use
JavaScript to do a job then I don't mind coding in JavaScript.
The newest version of Prototype.js has nice Ajax stuff but I haven't
found a way to do what the Yahoo! UI connection "argument" can do. See
the Yahoo! UI docs.
The Yahoo! UI library has a rediculous requirement that every dragdrop
element must have an id. I have to invent dummy ids for sortable list
elements. I hope this goes away. The sortable list options in both
libraries are not so great.
However with the power of the new rjs templates I am using
Prototype.js a little bit. Prototype.js is so integrated into the
rails way of doing things it might not be good to avoid it all
together. With rjs it feels like fighting to avoid Prototype.js.
The way my app is set up it is not a problem for the client to
download both some Yahoo and Prototype libraries. I might just happily
sit on the fence.

I don't even know Ruby but I love the Enumeration helpers. For
example, $A().without() is something you do often in javascript and
I'm happy not to have to write a for-next loop and test values
everytime I need to do it.
