I''m just getting started with GD2 and have successfully made a few dynamic PNGs. I need to make some fairly detailed line graphs on the fly and I know that GD2 is capable of what I want but I strongly suspect I''m reinventing the wheel badly. Are there gems or other projects that help creating complex charts? I''ve used GDChart in the distant past but I

Hi Everyone, This is basically an FYI because I don''t think there is much that can be done about it. I work at a DoD lab and up until very recently I had no problems at all getting to rubyonrails.org. All week long I have not been able to visit the site and I finally gave up and submitted a trouble call to our network help desk. I was told that the site was in a class B range

I have been very VERY frustrated for the past week trying to solve a seemingly spurious problem with my Windows XP SP2 box with Ruby 1.8.2/Rails 1.0.0/MySQL 5.0.16 or 4.1.15 (yes, I tried both) installed running against a remote MySQL server that was either 3.23 or 4.1 (4.1.15 to be exact--we finally matched them both up to make sure that wasn''t the problem). So I post it here (as

I've been attempting to get to get Shared Folders and ACL's to work under dovecot 1.0rc17. Unfortunately, I've run into some problems (many have already been mentioned on the list), specifically the problem where folder-specific ACL files are not found (and I will not use Global ACL's due to the 100% probability of cross-namespace mailbox name conflicts). My namespace

I developed a small RoR app on my Ubuntu laptop and I just tried to migrate it to my "production" box which is Fedora FC3. I moved the entire rails app. I received this error when I tried to get the first page: [2005-11-17 15:36:00] INFO WEBrick::HTTPServer#start: pid=32546 port=3000 192.168.0.61 - - [17/Nov/2005:15:40:01 EST] "GET /freesql HTTP/1.1" 200 0 - ->

Hi, I''m trying to setup rails 2.2.2 pool connections to MySQL by specifying the pool setting with 5 in database.yml but no hope.. It doesn''t work. My rails is running on webrick in the production mode and the webrick is launched by RadRails. Even though I send multiple requests to my app on rails at the same time, it seemed only one connection is shared ( pooled ). I also

Today I switched one of our servers from Courier (deployed 3-4y ago) to DCrc7. Everything seemed very nice (system load dropped significantly). Unfortunately after some time and ~8000 pop3-logins the main DC loop just quit without _any_ notice. Some pop3-login childs still showed up in the processlist, but the main listener on port 110 was gone. The above described scenario has been observed 2

Hello all, I''m trying to initialize my migrations against a current database implementation. rake db:schema:dump runs without error.

I''ve created a class method in my model called find_filtered. The intent is that I take various params that the user has submitted, and let the model build the query and return the AR collection, which is exactly what happens. However, now I''d like to paginate the recordset. Everything I''ve been able to find about pagination presumes that you have no pre-existing AR

Hi, I am just starting of in rails. I am trying to understand the features of rails and I have this burning question. (and search is not available now): Apart from relying on the automatic CRUD sql script produced, is there a way I can create my own sql script ex: with many joins between exixting tables (for reporting ). All I need is to declare the custom query and place the result in a

I had our production systems running on rc23, however we ran into problems when the server was under heavy load. Eventually, the server would begin to freeze all imap connection after authentication (according to the logs). A user would connect, authentication would succeed, and then the connection would sit until timing out. No error logs were produced. Upgrading to rc24 did not

Hi there I have a class method defined in my Product Model, ''featured_items'', which returns a recordset from the products table based on certain find conditions. I simply want to paginate this recordset, not the whole products table, using the paginate helper. After reading the Rails docs, I''m still struggling to work out how, in my ''list'' view, to

I have concluded that it is impossible to get this background process stable. I am out of ideas and could really use some help. Here is what I have: 50 workers, just running an infinite loop that constantly calls save! on a model. Keep in mind this is just for testing purposes. I catch all exceptions and put them in the log. I am tried setting allow_concurrency to true and false. Neither
