I'm building an API with Rails 4 and I really want to create a Batch request method to not overload my app when doing a bunch of ajax requests.
The Railscasts shows how to do it in a simple way but there's a lot of stuff missing.
I also tried the batch_api gem but I wasn't successful integrating it with my application.
Any ideas?
I know it's being late to answer this question but I recently used batch_api gem with my Rails API (rails 5.0.0 and Ruby 2.0) and it works find with me.
What you need to do is follow the instruction of this document:
https://github.com/arsduo/batch_api
Shortly:
1- You need to add the batch_api gem to your application GemFile.
2- You need to add the required middleware configuration in you application.rb file:
config.middleware.use BatchApi::RackMiddleware do |batch_config|
# you can set various configuration options:
batch_config.verb = :put # default :post
batch_config.endpoint = "/batchapi" # default /batch
batch_config.limit = 100 # how many operations max per request, default 50
# default middleware stack run for each batch request
batch_config.batch_middleware = Proc.new { }
# default middleware stack run for each individual operation
batch_config.operation_middleware = Proc.new { }
end
3- Then restart your rails server.
Make sure to insert the new middleware in the appropriate location, in my case I needed to include it before "ActionDispatch::RequestId" middleware.
config.middleware.insert_before "ActionDispatch::RequestId", BatchApi::RackMiddleware
because I wanted to include X-Request-ID header in each request in the Batch request and this ID will be returned in each response so that I could know the response for each request in the Batch (note that the responses will be executed sequentially depending on the sequence each request in the Batch).
Apparently the batch_api gem doesn't work with rails 4 yet, but there is a fork that was started to update it to rails 4 and ruby 2.0.

I want to caching api responses like
sitename.com/posts.json
for example for 5 minutes, where I must configure Rails and maybe what external tools I must use
just add
caches_page :posts, :expires_in => 5.minutes
it's explained decently on http://guides.rubyonrails.org/caching_with_rails.html#page-caching
Notice that expires_in only works with memcached as the cache store, AFAIK.
Uploading files won't work for me. The file does get saved but looking at the parameters there is no authenticity token sent by CKeditor. So I get a "Can't verify CSRF authenticity" warning, which resets the session, then I can't update the post.
The token is set in the form but CKEditor doesn't seem to send it for picture or file uploads. I think this may have been OK when I used CKE with Paperclip, but not certain of that. All other CKE operations work.
Answered at Ruby on Rails: problem getting CKeditor to upload images
You need to skip verification
skip_before_filter :verify_authenticity_token, :only => [:new_from_disk]
Please see the ckeditor code:
class Ckeditor::ApplicationController < ::ApplicationController
Please add some alike:
skip_before_filter :verify_authenticity_token
I am using devise in my application for authentication. When I try to register, I get the following error:
Missing host to link to! Please provide the :host parameter, set default_url_options[:host], or set :only_path to true
I am using :comfirmable and had uncommented t.confirmable in the migration
In order to use confirmable module you need to configure ActionMailer that is used by devise for sending confirmation emails. First step for solving your problem is setting up mailer host in you environment.rb or in the corresponding file for a particular environment like that:
config.action_mailer.default_url_options = { :host => “example.com” }
For further steps have a look at this rails guide and answers to this question.
I got an API that I have developed using Rails 3 and Devise. I am using tokens (token_authenticatable) for authentication for requests made to the API from a client. I want to be able to switch between users in the requests just be replacing the token.
I heard about a setting called :stateless_token (boolean) but I cannot figure out where to put this setting. Is there another way?
If found the token_authenticatable here:
https://github.com/plataformatec/devise/blob/master/lib/devise/strategies/token_authenticatable.rb
If found info about the stateless_token here:
http://rdoc.info/github/plataformatec/devise/master/Devise/Models/TokenAuthenticatable
stateless_token is deprecated as of now. This is the new form (it allows more auth strategies to be stateless):
# config/initializers/devise.rb
config.skip_session_storage = [:token_auth]
You can also edit the file /config/initializers/devise.rb and put (or uncomment, if already there) the following line:
config.stateless_token = true
It should be an option in your devise_for line in the routes file.
devise_for :users, :stateless_token => true
Let me know if that works,
In this page of documentation for devise it says that "TokenAuthenticatable adds the following options to devise_for:" with stateless token being one of them.
Also here is a link to the devise_for documentation
I am trying to split my current Ruby on Rails 3 web-application and it's web-services (API). My web-application is running on Heroku and implements API as a namespaced route within my application. For example /events returns a HTML page and /api/v1/events returns a JSON data.
According to some best practices, I want to split those into two different applications. I have chosen Sinatra to implement the API application. It works now for simple requests where authentication is not required.
My Ruby on Rails 3 application is using Devise to authenticate users. There's also ability to login with Facebook account. Now what I want to achieve, is HTTP Basic Authentication of users (including registration) through my Sinatra-based API by using Warden.
What is the best way to do that? Or maybe I can use something different then Warden?
Keep in mind that I am not very familiar with Rack :)
I was able to get it working. There were a few main aspects:
Get Devise working with Rails (Devise is a Rails app, won't work
without it)
Setup the mapping (route) on Rack level to support both Rails and Sinatra
Share the sessions between Rails and Sinatra
Setup Warden and make it available to Sinatra
Here is most relevant part of code from /config.ru:
#
# ...
# Rest with Rails
map "/" do
run MyApp::Application
end
# Anything urls starting with /slim will go to Sinatra
map "/slim" do
# make sure :key and :secret be in-sync with initializers/secret_store.rb initializers/secret_token.rb
use Rack::Session::Cookie, :key => '<< see, initializers/secret_store.rb >>', :secret => '<< copy from initializers/secret_token.rb >>'
# Point Warden to the Sinatra App
use Warden::Manager do |manager|
manager.failure_app = AppMain
manager.default_scope = Devise.default_scope
end
# Borrowed from https://gist.github.com/217362
Warden::Manager.before_failure do |env, opts|
env['REQUEST_METHOD'] = "POST"
end
run AppMain
end
