问题 I'm trying to open my MongoDB models, however, I'm getting the following error: MONGODB | xxx.xx.x.xxx:27017 | db.find | FAILED | wrong number of arguments (given 2, expected 1) | 0.013306s My Mongo credentials are correct, and I can connect to the database's collections outside of Rails.

问题 As suggested in http://railscasts.com/episodes/345-hstore, I added: serialize :properties, ActiveRecord::Coders::Hstore to my model. This allows me to iterate over key / value pairs in the view (without it, I get a undefined method `each' for String error): <% @item.properties.try(:each) do |key, value| %> <%= key %>: <%= value %><br /> <% end %> I managed to get the hstore field in RailsAdmin working by explicitly declaring it as a text field: class Item < ActiveRecord::Base attr_accessible

问题 In my application Product has many categories though category_has_products Category has many products though category_has_products Initially I used at product.rb default_scope { includes(:brand, :categories) } and in rails_admin config set it as field :categories, :string do searchable [{Category => :name}] end This works like a charm. This got in to performance issue due to has_many_through(other pages using product details got affected) So I removed the default_scope from product. After

问题 I have 3 tables, Activity, Activity_type and Itineraries. In activity type, I insert a new entry name => Testing => Example. In my activity, I can use the activity type I created earlier in my dropdown and type a location. In creating a new itinerary there's a dropdown activity and user(who created the new itinerary and choose what activity for the specific itinerary) but it only shows the activity #1 and user #1. In my list and i think this is the reason why it only display the Activity #1

问题 I'm building a custom action for rails admin that includes a custom view. I want to include a local copy of sparkline.js but I can't figure out a way to do this. I tried to add the sparkline.js to the /vendor/assets/javascripts/actions/action_name directory but it is not loaded by rails admin Is there any other way to get this file loaded 回答1: I did this by putting the external library into the app/assets/javascripts/rails_admin/custom directory and adding a 'require' statement to the rails

问题 I am building a JSON-only application, it is basically a leaner Rails, with fewer middleware and fewer modules. This is an application being built in Rails 4. I want to to develop a simple app that can administrate the data in the database for the main-app. For this I would like to use Active Admin or Rails Admin. But both options somehow use the underlying models and their validations, requirements and such to build on top of. This means that I need to share at least the models between the

问题 So i wanted to create an app, where people can view art. The problem is, only the admin should be able to create, edit and delete data. So i wanted to add an admin interface. I went with the rails_admin gem. I've installed everything as it said on the git documentation, but everything stopped working when I installed it. I can't generate scaffolds, models or controllers and I can't start my server. It gives me this message whenever I try something. /Users/Max/.rvm/gems/ruby-1.9.3-p194/gems
