similar to: using a helper from the console

Hi all, I''m trying to add a common menu to all pages in my application. It is just a set of links I want to display. I''m having trouble deciding where to put the code. Below is what I''ve tried to get out of the "Four Days on Rails" tutorial but no luck. Any help would be appreciated. Am I on the right track? Thanks, Sam

Hello, I''m facing this problem while trying to extend the parse_redmine_links helper method in Redmine-1.1.0 (Rails-2.3.5) from my plugin. My idea is to use alias_method_chain so the extended version could call the original version and adjust the result to it''s liking. Anything I''ve tried so far exposes this behavior: the first render of a page uses the extended

Hi, My helper specs were going ok until I added a call to a rails DateHelper method in one of my helpers http://api.rubyonrails.com/classes/ActionView/Helpers/ DateHelper.html#M000574 The helper runs fine from my view templates, just dies in the spec test. I boiled my question down to a simple (not too useful) example. I''m not sure what I''m missing. #

Is there some standard way to test migrations? It seems to me that an additional safeguard for migrations would be to test and see if applying the migrations to the test database allows one to reconstruct the structure of the development database. If you can''t, then there is an error in your migrations, most likely because someone hand-modified the database without generating a

Hi all, I''m in the process of creating rspecs for my helpers. One of the helpers in app/helpers/application_helper.rb looks like this: def page_name @page_name || "Define @page_name in #{controller.controller_name}::#{controller.action_name}" end The rspec is simply: it "should something" do page_name end

I am trying to run some functional (or are they unit?) tests on my application_helper.rb. So far, I''ve not had any success in being able to call the methods defined in application_helper.rb. Here is my app/test/functional/helpers.rb require File.dirname(__FILE__) + ''/../test_helper'' require File.dirname(__FILE__) +

Announcing RJSCallback 0.1 The RJS Callback plugin is being developed to provide Ruby On Rails with the ability to easily call RJS templates for the various callbacks associated with AJAX function calls (e.g., :before, :loading, :complete). Currently this plugin automatically detects, loads, and renders RJS templates with specific names and inserts them in the appropriate spot in

RJS templates are nifty. They let you put all sorts of fun effects all over your bland html pages without too much work. The link_to_remote function also lets you run scripts before, during, and after an AJAX call is run by using callbacks. There does not seem to be an equivalent method for running an RJS template before or during an action. Rendering it at the end is no problem. One

Hi, If I want to have helper method for my rjs, where''s the best place to put it? so for example: --- bla.rjs: page.replace_html ... page.visual_effect ... --- somewhere: (currently I put in application_helper.rb) def replace_with_effect(page) page.replace_html ... page.visual_effect ... end --- bla.rjs: replace_with_effect page and is there a way to define the helper so we

I''ve been trying to use the ez_where plugin to create a dynamic finder. The structure looks somehing like this.. === controller === def list attribute_filter = params[:filter] @filter = Caboose::EZ::Condition.new :table do attribute <=> attribute_filter if attribute_filter end # ... do the find with the @filter # end === view === .... <%= link_to

When working with views, I use instance methods of ApplicationHelper: # app/helpers/application_helper.rb: module ApplicationHelper def distribute(total, min, cutof, list) [1,2,3] end end # app/views/planner/_mta_colors.rhtml: <td> <% ... dist = distribute(total_v_px, 4, 0, colors.collect{|color| color[1]}) ... %> So to test the distribute method in ApplicationHelper, I have

Hi all I''m creating a shop page. I have a cart model that looks like the following: class Cart attr_reader :line_items def get_line_item id @line_items.each do |l| return l if l.id == id end end def initialize @line_items = [] end def empty! initialize end def empty? return true if @line_items.empty? false end end And I have some

I''m curious to see how others are dealing with the construction of multi-page forms. I can see a couple of ways to do this, each with their own advantages/disadvantates. Approach 1: * define one table with columns for each form entry. * define a method/view for each page, which only displays a subset of the fields. * submitting a page saves the data and moves on to the next page.

Hiall, Unfortunately I just can''t find out how to setup a default selected value when using collection_select. My call is like so: <%= collection_select(:consultant, :lastname, @consultants, :id, :lastname, { :selected => @current_consultant.id } ) %> which is not working, I debugged so far that I know that @current_consultant.id contains the correct value. Any tips? cheers

This isn''t really a scriptaculous question, but it might be interesting anyway. I''m generating a rails app and in one form I have a grid of check-boxes (rows = A..H and col=1..12). I would like to put a checkbox in the column/row headers to toggle the boxes in a particular row or column. Each box has a name like ''position_A1'' or

I''ve got an action in my application controller that needs to call a shared RJS template. Typically it''s actually being called by subclasses of the application controller. I''ve tried this.. def action ...code.. render :partial => "shared/template" end with ''_template.rjs'' existing in the shared folder. The problem that crops

Hi guys, I am a Rspec newbie and am having problems creating a spec for a RoR helper method. I have in fact already implemented the helper method and am trying to create retrospective specs. I know its the wrong way to do it but I am still learning Rspec. In my view I have a call to a helper method. <% body_class "users" %> which sets a CSS class declaration in the content_for

I''m using bundled_resource, login_engine, and a few other plugins. It appears Rails considers plugins in alphabetic order. Turns out that there is a particular order that will work and alphabetic ain''t it. The login engine must be loaded first. Bundled resource then includes ''application_helper'' and the application helper includes LoginEngine. If

Hi, I''m using scriptaculous to provide an auto complete textbox - and it works perfectly - but I was wondering if there was anyway to let users navigate the choices using the keyboard i.e the curor keys as opposed to having to use the mouse? Apart from that it''s perfect! :) Cheers, Pete -- Posted via http://www.ruby-forum.com/.
