Rails 3.1 Mountable Engines : How to use/template it inside another application?

阅读更多关于 Rails 3.1 Mountable Engines : How to use/template it inside another application?

问题 Let's say I created a mountable engine called 'Soho' that has a controller for 'Users'. I can go to /users/1 to see my user with ID 1. Inside 'Soho', I have a application.html.erb for layout. Now let's assume I want to "blend" my engine 'Soho' in an application called 'Soho_test', and I mount my engine at "/". So, in my host application 'Soho_test', I can also go at /users/1 to see my user with ID 1. This is working. My question is : how can I do in my host application 'Soho_test' to apply

问题 I have to add Wufoo-like WYSIWYG form-builder functionality to a Rails webapp. Does anyone know of good resources (gems/engines/plugins/example code) that would help? 回答1: this is not really an answer to your question, but I still can't add comments unfortunately, due to my reputation level, sorry :) There is exact equivalent of such functionality in Drupal(php) http://drupal.org/project/webform especially useful for contact forms, i.e. clients happy and don't bug me every time they want to

recaptcha plugin for rails

阅读更多关于 recaptcha plugin for rails

I am currently using ambethia's recaptcha plugin for rails. I want to disable the message "incorrect-captcha-sol" whenever the user incorrectly enters the wrong recaptcha. How should I go about doing this? In the source file I get the following tags surrounding the error message <p class="recaptcha_error">incorrect-captcha-sol</p> The plugin sets the flash (more precisely flash[:recaptcha_error]), i.e. it won't display message automatically. Most likely you have a piece of code that displays all flash messages. Try removing it and/or excluding flash[:recaptcha_error] from being displayed.

Gem-idea: Automatic spam protection with captcha in before_filter when HTTP-method is post,put or delete

阅读更多关于 Gem-idea: Automatic spam protection with captcha in before_filter when HTTP-method is post,put or delete

问题 I'm thinking about writing an automatic spam protection system (maybe I will write a public gem) for rails. My concept is to include a helper method in application_controller f.e.: class ApplicationController < ActionController::Base automatic_captcha_redirect(:min_time => 30.seconds :limit => 50) ... end Then I want to include automatical a before_filter in every controller, which checks, if the current request is via post, put or delete-method. If the user's last post-request is smaller

阅读更多关于 Saving the order of associated records in a Rails has_many :through association

问题 I'm working on a Rails plugin that includes a way to modify the order of associated records in a has_many :through association. Say we have the following models: class Playlist < ActiveRecord::Base has_many :playlists_songs, :dependent => :destroy has_many :songs, :through => :playlists_songs end class Song < ActiveRecord::Base has_many :playlists_songs, :dependent => :destroy has_many :playlists, :through => :playlists_songs end class PlaylistsSong < ActiveRecord::Base belongs_to :playlist

TypeError (can't convert nil into Integer):

阅读更多关于 TypeError (can't convert nil into Integer):

I developed a plugin in rails 3, which servers a a document repository for models. In any model you can attach any number of documents with specific names. Like. class Person < ActiveRecord::Base attach_documents_as :job_documents attach_documents_as :personal_documents end It was working very good. I know it looks to be stupid, but today i start my project and found it dead. Can not figure out why does it happens. Tried a lot to figure out but no luck. New and Update forms shows well but when ever we create or update it does generate an error. It is giving a major error: TypeError (can't
