ruby on rails - How to set in a middleware a variable accessible in all my application? -

-

i using ruby on rails 3 , trying use middlewares in order set variable @variable_name accessible later in controllers.

for example middleware is

  class auth      def initialize(app)       @app = app     end      def call(env)       @account ||= account.find(1)        @app.call(env)     end   end

the above code set @account variable, isn't available in application (in controllers, models, views, ...). so, how can accomplish that?

i seen this answer way need, have @account variable "directly accessible". is, without use way making available, example in views, this:

<%= debug @account %>

you can use 'env' that. in middleware this:

def call(env)   env['account'] = account.find(1)   @app.call(env) end

you can value using 'request' in app:

request.env['account']

and please don't use global variables or class attributes people suggest here. that's sure way troubles , bad habit.

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
