  • Rubyists: What is this called?

    - by Matt Darby
    Say I have a pool of enumerables that I want to group by an attribute: cars = Car.all.group_by(&:color) Then I want to iterate over those cars like so: cars.inject([]) do |stack, (color, cars)| stack << cars.each do |car| ... end end What is the term for the block variable extension (between the parentheses)?

  • Best way to create a preview functionality in rails

    - by slythic
    Hi all, I'm looking to implement a preview functionality in my posts scaffold. All I need to do is allow a user to enter information in the new view (/posts/new) and then replace the submit button with a preview button. Once the preview button is clicked, the user is routed to the preview page (probably /posts/new/preview). If the user wants to make a change they would click 'go back' or if they are happy with the post they can then submit the post. I found this article (http://eyedeal.team88.org/node/105) but it seems dated. Any ideas on what the best approach for this would be? Many thanks, Tony

  • Devise email confirmation from localhost

    - by John
    I am able to get the registration confirmation email to send out in deployment on Heroku, but when I try a registration on localhost:3000, I get the following error: undefined local variable or method `confirmed_at' for #<User:0xb67a1ff0> In my config/environments/production.rb file I have: config.action_mailer.default_url_options = { :host => 'xxxx.com' } And I have an initializer file with the following format: ActionMailer::Base.smtp_settings = { :user_name => "[email protected]", :password => "xxxxxx", :domain => "xxxx.com", :address => "smtp.sendgrid.net", :port => "xxx", :authentication => :plain, :enable_starttls_auto => true }; What settings do I need to get the localhost working? Thanks! John

  • Which testing method to go with? [Rails]

    - by yuval
    I am starting a new project for a client today. I have done some rails projects before but never bothered writing tests for them. I'd like to change that starting with this new project. I am aware there are several testing tools, but am a bit confused as to which I should be using. I heard of RSpec, Mocha, Webrat, and Cucamber. Please keep in mind I never really wrote any regular tests, so my knowledge of testing in general is quite limited. How would you suggest I get started? Thanks!

  • Monitor database table for external changes from within Rails application

    - by jhwist
    I'm integrating some non-rails-model tables in my Rails application. Everything works out very nicely, the way I set up the model is: class Change < ActiveRecord::Base establish_connection(ActiveRecord::Base.configurations["otherdb_#{RAILS_ENV}"]) set_table_name "change" end This way I can use the Change model for all existing records with find etc. Now I'd like to run some sort of notification, when a record is added to the table. Since the model never gets created via Change.new and Change.save using ActiveRecord::Observer is not an option. Is there any way I can get some of my Rails code to be executed, whenever a new record is added? I looked at delayed_job but can't quite get my head around, how to set that up. I imagine it evolves around a cron-job, that selects all rows that where created since the job last ran and then calls the respective Rails code for each row.

  • Using a join model to relate a model to itself

    - by Gabe Hollombe
    I have two models: User MentoringRelationship MentoringRelationship is a join model that has a mentor_id column and a mentee_id column (both of these reference user_ids from the users table). How can I specify a relation called 'mentees' on the User class that will return all of the users mentored by this user, using the MentoringRelationships join table? What relations do we need to declare in the User model and in the MentoringRelationship model?

  • Rails 3: How do I call a javascript function from a js.erb file

    - by user321775
    Now that I've upgraded to Rails 3, I'm trying to figure out the proper way to separate and reuse pieces of javascript. Here's the scenario I'm dealing with: I have a page with two areas: one with elements that should be draggable, the other with droppables. When the page loads I use jQuery to setup the draggables and droppables. Currently I have the script in the head portion of application.html.erb, which I'm sure is not the right solution but at least works. When I press a button on the page, an ajax call is made to my controller that replaces the draggables with a new set of elements that should also be draggable. I have a js.erb file that renders a partial in the correct location. After rendering I need to make the new elements draggable, so I'd like to reuse the code that currently lives in application.html.erb, but I haven't found the right way to do it. I can only make the new elements draggable by pasting the code directly into my js.erb file (yuck). What I'd like to have: - a javascript file that contains the functions prepdraggables() and prepdroppables() - a way to call either function from application.html.erb or from a js.erb file I've tried using :content_for to store and reuse the code, but can't seem to get it working correctly. What I currently have in the head section of application.html.erb <% content_for :drag_drop_prep do %> <script type="text/javascript" charset="utf-8"> $(document).ready(function () { // declare all DOM elements with class draggable to be draggable $( ".draggable" ).draggable( { revert : 'invalid' }); // declare all DOM elements with class legal to be droppable $(".legal").droppable({ hoverClass : 'legal_hover', drop : function(event, ui) { var c = new Object(); c['die'] = ui.draggable.attr("id"); c['cell'] = $(this).attr("id"); c['authenticity_token'] = encodeURIComponent(window._token); $.ajax({ type: "POST", url: "/placeDie", data: c, timeout: 5000 }); }}); }); </script> <% end %> undo.js.erb $("#board").html("<%= escape_javascript(render :partial => 'shared/board', :locals => { :playable => true, :restartable => !session[:challenge]}) %>") // This is where I want to prepare draggables. <%= javascript_include_tag "customdragdrop.js" %> // assuming this file had the draggables code from above in a prepdraggables() function prepdraggables();

  • Datamapper In Memory Database

    - by Daniel Ribeiro
    It is easy to setup Datamapper with a Sqlite3 in memory database with: DataMapper.setup :default, 'sqlite3::memory:'. However, when testing, I'd like to destroy the whole in memory database after each test, instead of invoking automigrate! as a shortcut on dropping everything. Is it possible? Or is it enough to set the default repository to nil, and let the garbage collector dispose of it?

  • An AuthLogic form is giving me incorrect validation errors -- why?

    - by sscirrus
    Hi everyone, I set up AuthLogic for Rails according to the AuthLogic example: http://github.com/binarylogic/authlogic_example. I can log on successfully to the system, but when accessing users/new.html.erb to register a new user, the form returns the following validation errors: Email is too short (minimum is 6 characters) Email should look like an email address. Login is too short (minimum is 3 characters) Login should use only letters, numbers, spaces, and .-_@ please. Password is too short (minimum is 4 characters) Password confirmation is too short (minimum is 4 characters) None of these errors exist in the data I am entering. # new.html.erb <%= form.label :login, nil, :class => "label" %><br /> <%= form.text_field :login, :class => "inputBox", :name => "login", :type => "text" %><br /> <%= form.label :password, form.object.new_record? ? nil : "Change password", :class => "label" %><br /> <%= form.password_field :password, :class => "inputBox", :name => "password", :type => "text" %><br /> <%= form.label "Confirm password", nil, :class => "label" %><br /> <%= form.password_field :password_confirmation, :class => "inputBox", :name => "password_confirmation", :type => "text" %><br /> <%= form.label :email, nil, :class => "label" %><br /> <%= form.text_field :email, :class => "inputBox", :name => "email", :type => "text" %><br /> # Users controller def new @user = User.new render :layout => "forms" end I think the problem is that the data isn't being transferred somehow and therefore AuthLogic doesn't think the inputs are sufficient. Do you have any idea why AuthLogic is telling me the data doesn't satisfy its validation?

  • Hot deploy on Heroku with no downtime

    - by zetarun
    A bad side of pushing to Heroku is that I must push the code (and the server restarts automatically) before running my db migrations. This can obviously cause some 500 errors on users navigating the website having the new code without the new tables/attributes: the solution proposed by Heroku is to use the maintenance mode, but I want a way with no downside letting my webapp running everytime! Is there a way? For example with Capistrano: I prepare the code to deploy in a new dir I run (backward) migrations and the old code continue to work perfectly I swith mongrel instance to the new dir and restart the server ...and I have no downtime!

  • Is Cancan's accessible_by my best choice for altering admin scope on the fly?

    - by evanchurchill
    Situation: On my site, I have a comment model, with a deleted field. Users cannot see deleted comments, but I would like to allow admins to see deleted comments, if they choose to. This will be accomplished by having a scope for users with the admin role which allows them to view comments with the deleted field set to false, as well as true. Question: Is Cancan's accessible_by method my best choice for doing so? From what I've read, it sounds like it will facilitate exactly what I'm trying to do, but, I don't want to implement something that is inefficient, if there is a better method.

  • How to pre-check checkboxes in formtastic

    - by trustfundbaby
    I have a form I'm trying to set up ... Users can have many posts, and each post can have many people watching it. The Watch model is set up polymorphically as 'watchable' so it can apply to different types of models. It has a user_id, watchable_id, watchable_type and timestamps as attributes/fields. This is soley so that when people comment on a post, users watching the post can get an email about it. What I'm trying to do is show the user a list of users that they can tag on each post, which is not problem. This is what I'm using right now http://pastie.org/940421 The problem with this, is that when you go to edit an update/post ... all the checkboxes are prechecked ... I want it to pre-check only users who are currently watching the post.

  • Nested form using accepts_nested_attributes_for with pre-population from another table

    - by mikeydelamonde
    I'm using Rails 2.3.5 and have a nested structure as follows: Lists has_many Items Items_Features has_many Features Items_Features has_many Items Items_Features has a text field to hold the value of the feature Then I have a nested form with partials to update and display this so that it updates Lists, Items and Items_Features What I want to do is generate input fields for each of the rows in features so that the user can fill in a value and it gets inserted/updated in items_features. I also want a label next to the box to display the feature name. It might look like this: List name: Cheeses Item1 name: Edam Feature, hardness: - fill in - <= this list of features from feature table Feature, smell: - fill in - How can I interrupt the nice and easy accepts_nested_attributes_for system to display this as I want?

  • Rails render partial with block

    - by brad
    I'm trying to re-use an html component that i've written that provides panel styling. Something like: <div class="v-panel"> <div class="v-panel-tr"></div> <h3>Some Title</h3> <div class="v-panel-c"> .. content goes here </div> <div class="v-panel-b"><div class="v-panel-br"></div><div class="v-panel-bl"></div></div> </div> So I see that render takes a block. I figured then I could do something like this: # /shared/_panel.html.erb <div class="v-panel"> <div class="v-panel-tr"></div> <h3><%= title %></h3> <div class="v-panel-c"> <%= yield %> </div> <div class="v-panel-b"><div class="v-panel-br"></div><div class="v-panel-bl"></div></div> </div> And I want to do something like: #some html view <%= render :partial => '/shared/panel', :locals =>{:title => "Some Title"} do %> <p>Here is some content to be rendered inside the panel</p> <% end %> Unfortunately this doesn't work with this error: ActionView::TemplateError (/Users/bradrobertson/Repos/VeloUltralite/source/trunk/app/views/sessions/new.html.erb:1: , unexpected tRPAREN old_output_buffer = output_buffer;;@output_buffer = ''; __in_erb_template=true ; @output_buffer.concat(( render :partial => '/shared/panel', :locals => {:title => "Welcome"} do ).to_s) on line #1 of app/views/sessions/new.html.erb: 1: <%= render :partial => '/shared/panel', :locals => {:title => "Welcome"} do -%> ... So it doesn't like the = obviously with a block, but if I remove it, then it just doesn't output anything. Does anyone know how to do what I'm trying to achieve here? I'd like to re-use this panel html in many places on my site.

  • Rails best practice on conditional parameters in a controller action

    - by randombits
    I have a controller create action looks for one or more parameters in the following ruleset. Let's say we have two parameters, foo and bar. The rules are the following: 1) if foo doesn't exist in the parameter list, bar must. 2) if bar doesn't exist in the parameter list, foo must. 3) they can both co-exist. they can't both be omitted (that's redundant with my rules above :) ) Can anyone show an example in Rails on how this is handled in the controller? Should I use a before_filter? Would appreciate some guidance as this isn't something that ActiveRecord validates.. so I'd need to build an error message to the user directly from controller logic, not model logic. For bonus points, I output the error in XML, so if you can show how that's done, that'd be great. Hypothetically let's call the resource "Lorem", so it is created via http://foo/lorem.xml and we have lorem_controller.rb.

The required behaviour is as follows: I have a link(with a ajax link embedded) xyz.com/admin#page1 When I go to the above page, I should be redirected to the login page, if I am not logged in.

The problem is that when I do request.uri, I get xyz.com/admin But I want to store xyz.com/admin#page1 Regards, Pankaj

  • Rails unknown action suddenly everywhere

    - by Joe
    The weird thing is that my app was working perfectly on Sat, and when I check it out on Monday (after doing nothing to it) I kept getting this problem: This behaviour is only happening on my production server. When I try to login or create a new user or do something that interacts with a form I am getting an unknown action error. A simple retrieval of rows does not throw this error however. I don't have all CRUD operations in most of my controllers because it's not necessary - but Rails always looks for the one that doesn't exist - it seams so anyway. If I make a mistake in the form that would normally throw a validation message to the user it will throw this error too, does that mean it has something to do with the model too (I'm not too Rails experienced and didn't know if that would be the case or not)? This is a general error I am getting - I have super_exception_notifier gem installed, so that's what all the extra params are.

Like I said it only throws this in a production environment, which guess is what the 'env' variable is referencing. Thank you for your time! I've spent nearly my whole day trying to figure this out! :(

  • rails ajax redirect

    - by badnaam
    Here is my use case I have a search model with two actions search_set and search_show. 1 - A user loads the home page which contains a search_form, rendered via a partial (search_form). 2 - User does a search, and the request goes to search_set, the search is saved and a redirect happens to search_show page which again renders the search_form with the saved search preferences. This search form is different than the one if step1, because it's a remote form being submitted to the same action (search set) 3 - Now the user does another search, and the search form is submitted via ajax to the search_set action. The search is saved and executed and now I need to present the result via rjs templates (corresponding to search_show). I am told that if the request is xhr then I can't redirect to the search_show action? Is that right? If yes, how do I handle this? Here is my controller class http://pastie.org/993460 Thanks

  • Rails: Getting rid of "X is invalid" validation errors

    - by DJTripleThreat
    I have a sign-up form that has nested associations/attributes whatever you want to call them. My Hierarchy is this: class User < ActiveRecord::Base acts_as_authentic belongs_to :user_role, :polymorphic => true end class Customer < ActiveRecord::Base has_one :user, :as => :user_role, :dependent => :destroy accepts_nested_attributes_for :user, :allow_destroy => true validates_associated :user end class Employee < ActiveRecord::Base has_one :user, :as => :user_role, :dependent => :destroy accepts_nested_attributes_for :user, :allow_destroy => true validates_associated :user end I have some validation stuff in these classes as well. My problem is that if I try to create and Customer (or Employee etc) with a blank form I get all of the validation errors I should get plus some Generic ones like "User is invalid" and "Customer is invalid" If I iterate through the errors I get something like: user.login can't be blank User is invalid customer.whatever is blah blah blah...etc customer.some_other_error etc etc Since there is at least one invalid field in the nested User model, an extra "X is invalid" message is added to the list of errors. This gets confusing to my client and so I'm wondering if there is a quick way to do this instead of having to filer through the errors myself.

  • 'button_to' gives me an ugly URL!

    - by Tyler
    Im trying to get an 'add to cart' button to work. When I use <%= button_to "Add to Cart", :acton = "add_to_cart", :id = @product % and then click the button, I get a URL that puts the action after the ID, like this: 'http://localhost:3000/store/show/1?acton=add_to_cart.' The cart page does not load. What I need is a URL that looks like this: 'http://localhost:3000/store/add_to_cart/1'. I can get that result (and the cart to work) if I don't use 'button_to': <% form_for @product, :url = {:action = "add_to_cart", :id = @product} do |f| % <% end % But, what the heck? Why can't I use 'button_to'?

  • How do I add Polylines in gmaps4rails v2

    - by LaraF
    I upgraded to the latest version of gmaps4rails (v2) and am having some issues getting polylines drawing. I can get markers working with the sample code on the wiki, but if I change the addMarkers to addPolylines, nothing renders in the map. Here's the handler code: handler = Gmaps.build('Google'); handler.buildMap({ provider: {}, internal: {id: 'map'}}, function(){ polylines = handler.addPolylines([{"lat":45.678295,"lng":-121.603813,"ele":438.626221,"time":1381851321},{"lat":45.678196,"lng":-121.603607,"ele":423.202148,"time":1381851363},{"lat":45.678181,"lng":-121.603607,"ele":421.108398,"time":1381851373},{"lat":45.678162,"lng":-121.603584,"ele":420.153442,"time":1381851383},{"lat":45.678123,"lng":-121.603569,"ele":422.561096,"time":1381851393},{"lat":45.678165,"lng":-121.6036,"ele":425.191284,"time":1381851403},{"lat":45.678169,"lng":-121.603607,"ele":425.262329,"time":1381851413}]); handler.bounds.extendWith(polylines); handler.fitMapToBounds(); }); No errors in the javascript console, just no map rendering. Any thoughts?
