similar to: render_to_string and DoubleRender error

Hi all, I know that in general, view and controller tests should be isolated, such that controller specs don''t test views etc. However, I think I''ve run into a situation that might be an exception. My controller uses render_to_string to produce a chunk of HTML that it passes to a model to be processed. The controller then redirects the user to a different page. The

I want to clean my code by moving the duplicated lines : partial = render_to_string( :partial => "#{file}", :formats => [:html] ) to the pagination_partials function. ================================================= WORKING CODE: ================================================= def render_format_search_partial(file, options={}) # TODO remove this line to use the one

Hello, my question is rails related though it is also somewhat specific to the prawnto plugin (installed latest version as of 2010-03-15). I would ask on a prawnto forum/list if I knew where one was. Anyhow, I''m using rails 2.3.5 (with ruby 1.8.6 patchlevel 111) in an app that is successfully using the prawnto gem (with the prawn gem version 0.7.1). I''ve got a a

When I have a user go to a certain page, it will fork off a thread that will perform some action. So the main thread will finish and render :nothing => true . Now, I want that forked off thread to render into a string a partial. However, I cannot render_to_string :partial=> :foobar because I have already rendered once. Is there anyway to get around this? -- Posted via

Hi, I''m trying to build a simple mechanism for pre-caching a bunch of files by iterating over a hash of options from within a controller: #site.controller: for options in [ { :controller => "site", :action => "welcome" }, { :controller => "site", :action => "about" }, { :controller => "site", :action

Greetings, I''ve got a rails app which is basically an admin interface to a xml dataset. Currently I''ve got rails rigged to call a function to spit the entire dataset to file with every change. This would actually be ok, its fairly infrequently updated, but when the dataset grows large the user sits there waiting for it to dump with no feedback as to whats going on. Oh yes,

Is it possible to call render_to_string() in a controller that is not set as the default route? The content controller is set in routes.rb: map.connect '''', :controller => "content". The content controller is calling a template controller, and I would like to be able to call render_to_string() within the template controller, however I receive the error:

I use render_to_string to generate short reports (in HTML) under certain conditions when users access my application. The reports are stored in the database and uses database information at the time they are generated (and can thus not be generated later, e.g; when you want to consult them). The reports are generated the same way regardless of which controller has been accessed. Conditions for

I have a model (Query) which I use to, of all things, query the database. This is to enable raw SQL access. I want to ensure that db access using this model is read-only. Short of checking the sql query for ''insert'' and ''drop'' and ''update'', is there a more rails-like way of doing this in my app/models/query.rb itself? Thanks in advance,
