Is it possible to declare an instance variable in a controller that is available to every action without defining the variable in every action? -- Posted via http://www.ruby-forum.com/.

I was thinking about having instance variable stored and fetched from session container automatically before calling an action and after the action is finished. Using methodology of accessors it would look like: class MyController < ActionController::Base persistent_attr :person def alfa person = ''John Smith'' # render as usual view alfa.rhtml with anchor

So, under Sqlite2, if I want to update a database''s schema, I have to dump the DB, modify the table''s structure, then go and modify EVERY insert statement. The insert statements look like (from memory): INSERT INTO my_table VALUES (''some_id'', ''some_val'', '''', '''', '''', ''some_other

Hi! I want to add a function with a static paramter ("2" in the example) to a filter, but somehow Rails seems to be looking for another syntax. before_filter :check_quantity(2), :only => [:show] doesn''t work.

i am trying to create a system so that different users have different priviliges on my application. i was going to modify my authorize function so that i could pass the required role to it and have it check the current user for that role. i am using before_filter and would like to have just one function instead of writing one for each role like so: authorize(role) instead of:

Hello list, I have an app that has a very simple authorization scheme. A person can have many roles and roles can have many people. In my app, I''d like to do before_filter :login_required (since no role name is provided, it accepts any users with credentials) before_filter :login_required ("administrator") (only accepts those with role administrator) before_filter

Can you restric before_filter to specific actions? -- Posted via http://www.ruby-forum.com/.

Hello everyone, Samba 3.6.9 on CentOS 6.4. With "security = ads", winbind doesn't authenticate requests that prepend a not-existent domain to the username.

In asp there''s a built''in object, Application, which behaves like the session, but it allows you to share information among all users of the application. (http://www.microsoft.com/windows2000/en/server/IIs/default.asp?url=/windows2000/en/server/IIs/htm/asp/vbob6zkv.htm) It''s just like if every user would be accessing the same session. what is the rails equivalent?

I have multiple roles in my application. Now I want to block a method for all users except the administrator and a manager.

How can I change that to an "OR" combination? -- Posted via

One of these days I''ll figure this out, but in the meantime help me be a better programmer by eliminating some excess code: I''m trying to check to see if somebody trying to view/edit/update a product is the owner.
