Hi, anyone have any experience compiling/installing Cassandra and thrift on CentOS? Thx, JD

An easy way to start troubleshooting these is to look at the audit logs and see what SELInux is blocking. You have /McFrazier in the email.. if that's off the root tree than unless you've set permissions to allow httpd to look at tat folder, I bet that's one problem. if you run ls -Z you can see the labels that are present on those folders, that might be helpful too. On Wed, Mar 4,

Hey all, There's a website I help run that uses the Cassandra DB as its database. I notice that if I run the web server in SELinux permissive mode, the site works fine. But if I put it into enforcing mode, the site goes down with this error: Warning: require_once(/McFrazier/PhpBinaryCql/CqlClient.php): failed to open stream: Permission denied in

I asked this question before, but didn''t get any response. I hope someone can give me some clue now. Here''s the background, I upgraded to rails 1.1 and suddenly I was getting strange failures in my functional tests. I traced the problem to dynamic scaffolding. I had overwritten all of scaffold''s methods in my controller (all but show and destroy). Destroy no

Now that were designing are controllers to just be CRUD, scaffolding makes a lot of sense (DHH must of had this planed from the beginning). The current scaffolding should be modified to better fit Resources. Scaffolding doesn''t need to be redone, it just needs a few tweaks. I''ve already started converting the scaffold method. I made a plugin, but it still needs some work.

After I downloaded this plugin, I am not sure how to use it. According the doc: Generally, the scaffolding extensions are used in same way as the normal scaffolding. Inside a controller, run the command: scaffold :album But I tried to run scaffold :control_name, (I have table in the database) in the app/controller, the system says " scaffold: command not found" Suggestion? Thanks in

Hello all, I am a bit hung up. I have created a simple table (pluralized) named aircrews and I have edited my database.yml file to point to the database that I created and that is holding the table aircrews. I have gone through the depot tutorial in the Agile book and when I have run the scaffolding command for the depot app all has worked fine for the table products. Now when I run the ruby

Hey all, I''m just starting in rails and am working on my first app. I need to do inline editing for 2-15 rows of data on a page. I found Ajax Scaffolding here: http://www.ajaxscaffold.com/ And it is EXACTLY what I want in my app. But I''ve also been trying to read a bit up on RJS Templates. Are they basically the same things except RJS is built into rails or is the

I am having trouble generating some of my scaffolding. I''m trying to use PostgreSQL as my back-end. Some of my scaffolding generates with no problem but for other parts I get this: Before updating scaffolding from new DB schema, try creating a table for your model The tables do exist. At least I can see them from psql. Here is the SQL I''m using to create my tables: CREATE

I''m creating a photo blog with ror. The front end has gone great, so now I''m working on the back end, and was playing with scaffolding. I generated these scaffolds: ruby script/generate scaffold Photo admin/photo ruby script/generate scaffold Camera admin/camera Then, in my routes, I added this line: map.connect ''/admin'',

Hi, I would like to know if there is a way to maintain database reflection for the ''new'' and ''edit'' views whilst removing scaffolding? I''m trying to create a webapp that will be somewhat maintainable by colleagues (that aren''t necessarily web developers) through simple manipulation of db table fields. For example to add another field to the

It occurs to me as a missing feature that there''s no way to indicate a lookup table relationship (as opposed to other sorts of foreign key relationships) in Rails and that the scaffolding generator could recognise this lookup and render a drop-down list automagically for the lookup table. Say you have an Address and a State, and the State is a lookup table. In addresses you have

What does everyone on this list think about enhancing scaffolding somehow so that a "has_many" relationship will automatically drop the <select> box into the view to reference the "belongs_to" part of the view? I think scaffolding is great but I am always adding the <select> boxes to reference the parent association. Do you think this would be useful? just a

I saw some interesting mails from TImo back in 2009 talking about the idea of using something like Cassandra db or similar as a storage platform for both email and index/logs. I was wondering if this has been discussed since then, and if there are any plans to support something like this in the future? I have been playing with Cassandra and found that their RackAwareStrategy gives you the

Hi, I''m going through the Depot tutorial in the book "Agile Web Development with Rails" and I can''t even get past the very first step. I''m getting the following error: "Before updating scaffolding from new DB schema, try creating a table for your model (Product)" when I try to run "ruby script/generate scaffold Product Admin. I have a table

Allo, Just started playing around with RoR/scaffolding and have been impressed so far. However, it seems to create a 1:1 relationship between Controllers and Models and the basic CRUD actions -- I need to CRUD two models from the same views and actions. I have: Book model Book controller, with create/edit/show/destroy/list actions and the scaffold-gen''ed views. Category model Category

When using ruby to generate scaffolding, is there an easy way to add features that would be useful for keeping track of has_many and belongs_to relations? For example, suppose I have the following: Users Sites Pages Modules Each user has many pages, each site has many pages, each page has many modules, and also the belongs_to relation holds in the opposite order. I''m using the
