Here's the rundown of the problem that I'm having:
I have a page that I am rendering that has multiple icons being
displayed. The icons are being stored as binary files in the database.
When I load the page with a collection of items (icons) to be
displayed, not all of the icons are being displayed. In fact, the
icons which actually get displayed seem a bit random.
>From the main html file, a partial is called for each of the items:
<% if @new_items -%>
<ol>
<li><%= render :partial => 'shared/item', :collection =>
@new_items, :spacer_template => 'shared/li' %></li>
</ol>
<% end -%>
Inside the partial, each image is rendered with the following code:
<img src="<%= url_for(:action => 'get_icon', :id => item.id) %>"
alt="Unable to Display" class="uas-app-icon-link"/>
The get_icon method is just a function which contains the following:
def get_icon
item = ItemDocument.find(:all, :conditions => ["item_id == ?
AND
id == (SELECT
icon_id
FROM
items
WHERE
id == ?)",
params[:id],
params[:id]])
icon = item[0]
send_data(icon.file,
:type => icon.content_type, :disposition =>
"inline")
end
Anyways, only some of that actual images are actually rendered when
the page is complete. I checked to see whether the urls exist for each
image, and all of the image urls are fine; they render just as they
should. I have tried using both WEBrick and Mongrel in my server
configuration of the localhost. WEBrick is a bit better, but both of
them still fail to some extent. The server log for WEBrick is the
following:
Processing ApplicationController#get_icon (for 127.0.0.1 at
2009-09-01 15:45:05) [GET]
Parameters: {"id"=>"2"}

Currently I am using sqlite3 v3.6.17 (gem) and rails v2.3.3 if that
helps any. I did try making a quick temporary project that did the
same kind of rendering with send_data and an iterating partial call,
and it has the same behavior. I tried using both sqlite and mysql
v5.0.85 (v2.8.1 gem), and the results were the same. Any help at this
point would be greatly appreciated. I am a beginner just to let you
know, just FYI for those who might be able to help out. Thanks in
advance.
