  • Where to put plugins in a Zend Framework website

    - by Matthieu
    Hi all, The question is quite simple : I have a plugin for Zend Framework. Should I put it in the "library/Plugin" folder, or in "application/plugins". (btw for now it is in library/Plugin but this works on Linux and Mac Os X, but not Windows so i figured maybe that is not the right place) Thank you

  • Zend Framework: Controller Plugins vs Action Helpers

    - by Laimoncijus
    Could someone give few tips and/or examples how Controller Plugins and Action Helpers are different? Are there situations where particular task could be accomplished with one but not another? For me they both look more or less the same and I'm often having trouble having to decide when to use what... Are there any big differences?

  • What are the Rails best practices for javascript templates in restful/resourceful controllers?

    - by numbers1311407
    First, 2 common (basic) approaches: # returning from some FoosController method respond_to do |format| # 1. render the javascript directly format.js { render :json => @foo.to_json } # 2. render the default template, say update.js.erb format.js { render } end # in update.js.erb $('#foo').html("<%= escape_javascript(render(@foo)) %>") These are obviously simple cases but I wanted to illustrate what I'm talking about. I believe that these are also the cases expected by the default responder in rails 3 (either the action-named default template or calling to_#{format} on the resource.) The Issues With 1, you have total flexibility on the view side with no worries about the template, but you have to manipulate the DOM directly via javascript. You lose access to helpers, partials, etc. With 2, you have partials and helpers at your disposal, but you're tied to the one template (by default at least). All your views that make JS calls to FoosController use the same template, which isn't exactly flexible. Three Other Approaches (none really satisfactory) 1.) Escape partials/helpers I need into javascript beforehand, then inserting them into the page after, using string replacement to tailor them to the results returned (subbing in name, id, etc). 2.) Put view logic in the templates. For example, looking for a particular DOM element and doing one thing if it exists, another if it does not. 3.) Put logic in the controller to render different templates. For example, in a polymorphic belongs to where update might be called for either comments/foo or posts/foo, rendering commnts/foos/update.js.erb versus posts/foos/update.js.erb. I've used all of these (and probably others I'm not thinking of). Often in the same app, which leads to confusing code. Are there best practices for this sort of thing? It seems like a common enough use-case that you'd want to call controllers via Ajax actions from different views and expect different things to happen (without having to do tedious things like escaping and string-replacing partials and helpers client side). Any thoughts?

  • Ruby on Rails vs Grails vs. Spring ROO vs. Spring App

    - by lizdev
    Hi, I'm planning on writing a simple web application that will be used by lots of users (as complicated as a simple bookmarking app) and I'm trying to decide which framework/language to use. I'm very experienced with Spring/Hibernate and Java in general but new to both Grails and RoR (and Spring ROO). The only reason I'm considering RoR is because Java hosting is MUCH more expensive than RoR hosting (which is supported by almost any hosting vendor for 5$ per month). Assuming the price wasn't an issue, which one of the frameworks/languages mentioned above would you recommend for a Java developer (who knows how to configure Spring/Hibernate etc.)? I'm afraid that by using RoR I won't be able to easily support many users who are using the website at the same time. thanks

  • Dynamic State Machine in Ruby? Do State Machines Have to be Classes?

    - by viatropos
    Question is, are state machines always defined statically (on classes)? Or is there a way for me to have it so each instance of the class with has it's own set of states? I'm checking out Stonepath for implementing a Task Engine. I don't really see the distinction between "states" and "tasks" in there, so I'm thinking I could just map a Task directly to a state. This would allow me to be able to define task-lists (or workflows) dynamically, without having to do things like: aasm_event :evaluate do transitions :to => :in_evaluation, :from => :pending end aasm_event :accept do transitions :to => :accepted, :from => :pending end aasm_event :reject do transitions :to => :rejected, :from => :pending end Instead, a WorkItem (the main workflow/task manager model), would just have many tasks. Then the tasks would work like states, so I could do something like this: aasm_initial_state :initial tasks.each do |task| aasm_state task.name.to_sym end previous_state = nil tasks.each do |tasks| aasm_event task.name.to_sym do transitions :to => "#{task.name}_phase".to_sym, :from => previous_state ? "#{task.name}_phase" : "initial" end previous_state = state end However, I can't do that with the aasm gem because those methods (aasm_state and aasm_event) are class methods, so every instance of the class with that state machine has the same states. I want it so a "WorkItem" or "TaskList" dynmically creates a sequence of states and transitions based on the tasks it has. This would allow me to dynamically define workflows and just have states map to tasks. Are state machines ever used like this?

    I am using Savon to build the client, but want to kno how to create the actual envelope. I am thinking of using Nokogiri XML Builder and just pass in the values, but not sure if that's the right way.

  • What is the right way to initialize a constant in Ruby?

    - by zbrimhall
    I have a simple class that defines some constants, e.g.: module Foo class Bar BAZ = "bof" ... Everything is puppies and rainbows until I tell Rake to run all my Test::Unit tests. When it does, I get warnings: bar.rb:3: warning: already initialized constant BAZ My habit has been to avoid these warnings by making the constant initialization conditional, e.g.: ... BAZ = "bof" unless const_defined? :BAZ ... This seems to solve the problem, but it is a little tedious, and I don't ever see anyone else initializing constants this way. This makes me think I might be Doing It Wrong. Is there a better way to initialize constants that won't generate warnings?

  • How to use class_eval <<-"end_eval" in Ruby? Not parsing correctly

    - by viatropos
    I would like to define dynamic methods based on some options people give when instantiating it. So in their AR model, they'd do something like this: acts_as_something :class_name => "CustomClass" I'm trying to implement that like so: module MyModule def self.included(base) as = Config.class_name.underscore foreign_key = "#{as}_id" # 1 - class eval, throws these errors # ~/test-project/helpers/form.rb:45: syntax error, unexpected $undefined # @ ||= MyForm.new( # ^ # ~/test-project/helpers/form.rb:46: syntax error, unexpected ',' #~/test-project/helpers/form.rb:48: syntax error, unexpected ')', # expecting kEND from ~/test-project/helpers.rb:12:in `include' base.class_eval <<-"end_eval", __FILE__, __LINE__ attr_accessor :#{as} def #{as} @#{as} ||= MyForm.new( :id => self.#{foreign_key}, :title => self.title ) @#{as} end end_eval end end But it's throwing a bunch of errors I've printed in the comments. Am I using this incorrectly? What are some better ways I can define dynamic method names and dynamic names inside the method like this? I see people use this often instead of define_method (see these classes in resource_controller and couchrest toward the bottom). What I missing here? Thanks for the help

  • Ruby on Rails redirect_to not functioning in IF statement?

    - by Hard-Boiled Wonderland
    Hi, I am redirecting a POST request to ensure the URL is correct along with other things. The redirect worked fine before I added in the if statements for town below: if !params[:address].blank? town = Town.find(:all, :conditions => ["name = ?", params[:address]]) @towns = town if !town.blank? redirect_to '/town/' + params[:address] else @town_invalid = 'test' end end end I am sure it is something simple and that I simply cannot see it. Also if you see any glaring errors or code mishaps let me know as I am just starting out. EDIT: I should mention this is what I get back from Safari when a real town is entered: Safari can’t open the page.Safari can’t open the page “http://localhost:3000/” because the server unexpectedly dropped the connection. This sometimes occurs when the server is busy. Wait for a few minutes, and then try again. Thanks!

  • Would Ruby on Rails be appropriate for this Foreign Language project?

    - by Lynne Overesch-Maister
    I'm a Spanish professor & computer groupie. About 15 years ago, I authored in HyperCard a series of verb conjugation programs that are now completely out of date with respect to System OS X. I would like to redo these programs myself because I had a lot of fun doing them last time (mostly I coded while my son played in Leaps and Bounds, you know, one of those places where parents take their kids & let them run wild through the tubes...). Colleagues have mentioned using Flash, Director, and various other solutions, but I saw a presentation on RoR at our SIDLIT conference today, and was inspired. I will be parsing and comparing strings (and there are other features on top of that, but that is the main one), "adding" strings relationally indexed in some kind of database(s). It will also have to handle various foreign characters (accents, upside down question marks, etc.). On top of the main process of the program, it will have to provide a practice vs. test mode, keep track of specific answers as well as totals right/wrong, and print a report. Would this be either easier and/or more efficiently done in RoR than in other languages. I am pretty sure that it will work on a Microsoft server, right? Because I think that is where most of our stuff is. I would be programming either on a Mac or a PC, whichever you think is easier. So, in summary, is RoR the way for me to go with this project? If I have some (little) experience programming in Hypercard and C, should I be able to pick RoR up fairly quickly? What things will I need to start (I already saw something called Redhills foreign key migration plugin, which I assume would be beneficial)? I still have my old scripts from hypercard, however what I would really like to do is to combine all six of my former tense-specific programs into one larger program. I figure that it wouldn't be too hard to reference the individual tenses in some way--could that be a class? Many thanks for any help you can give me on this forum.

  • On Ruby on Rails, <%= or <% should only matter whether it is show or no show, but why will it give

    - by Jian Lin
    The following code: <div id="vote_form"> <%= form_remote_tag :url => story_votes_path(@story) do %> <%= submit_tag 'shove it' %> <% end %> </div> gives compilation error while if the first <%= is replaced with <%, then everything works. I thought they only differ by "show" or "not show", but why will it actually cause a compile error? The error is: > SyntaxError in Stories#show > > Showing > app/views/stories/show.html.erb where > line #17 raised: > > compile error C:/Software > Projects/ror/shov12/app/views/stories/show.html.erb:17: > syntax error, unexpected ')' ... > story_votes_path(@story) do ).to_s); > @output_buffer.concat ... > ^ C:/Software > Projects/ror/shov12/app/views/stories/show.html.erb:23: > syntax error, unexpected kENSURE, > expecting ')' C:/Software > Projects/ror/shov12/app/views/stories/show.html.erb:25: > syntax error, unexpected kEND, > expecting ')'

  • In Ruby are there any related applications of the syntax: class << self ... end

    - by pez_dispenser
    class << self attr_accessor :n, :totalX, :totalY end The syntax above is used for defining class instance variables. But when I think about what syntax implies, it doesn't make any sense to me, so I'm wondering if this type of syntax is used for any other types of definitions. My point of confusion here is this: class << self The append operator normally means "add what's on the right to the object on the left". But in the context of this block, how does that add up to "put the contents of this block into the definition of the class instance rather than the instance"? For the same reason I'm confused as to why in one context class << self can define class instance variables while in another it seems to create class variables such as here: class Point # Instance methods go here class << self # Class methods go here end end

  • How do I validate XML via RELAX NG in Ruby?

    - by cdleary
    The REXML module appears to have support for RELAX NG validation, but the docs don't have any real information on using the validation portion of the framework. How would you validate an XML document with a RELAX NG schema? A code snippet would be most helpful. TIA!

  • Is it legal to stub the #class method of a Mock object when using RSpec in a Ruby on Rails applicati

    - by MiniQuark
    I would like to stub the #class method of a mock object: describe Letter do before(:each) do @john = mock("John") @john.stub!(:id).and_return(5) @john.stub!(:class).and_return(Person) # is this ok? @john.stub!(:name).and_return("John F.") Person.stub!(:find).and_return(@john) end it.should "have a valid #to field" do letter = Letter.create!(:to=>@john, :content => "Hello John") letter.to_type.should == @john.class.name letter.to_id.should == @john.id end [...] end On line 5 of this program, I stub the #class method, in order to allow things like @john.class.name. Is this the right way to go? Will there be any bad side effect? Edit: The Letter class looks like this: class Letter < ActiveRecord::Base belongs_to :to, :polymorphic => true [...] end I wonder whether ActiveRecord gets the :to field's class name with to.class.name or by some other means. Maybe this is what the class_name method is ActiveRecord::Base is for?
