can't use fragment caching with render_anywhere

Question

can't use fragment caching with render_anywhere

Closed this issue 11 years ago · 15 comments

Hi there,

When I try to use fragment caching with render_anywhere, I get this error:

Rendered reviews/print.html.haml within layouts/print (592.2ms)
ActionView::Template::Error: undefined method `perform_caching' for #<RenderAnywhere::RenderingController:0x007fb5e9c7dcc8>
from /Users/steven/.rvm/gems/ruby-1.9.2-p320/gems/actionpack-3.2.11/lib/action_view/helpers/cache_helper.rb:35:in `cache'

In production.rb and development.rb I have:

config.action_controller.perform_caching = true

Hi Steven,

I'm away this weekend but I'll take a look next week. Can you let me know what version of Rails you're using and if possible provide a snippet of code of how you're using this to get this error?

Thanks

Thanks. I'm on Rails 3.2.1. I call it like this:

require 'render_anywhere'
class Review < ActiveRecord::Base
  include RenderAnywhere

  def create_pdf
    css = Rails.application.assets.find_asset('print').to_s
    @mc = marker_count
    html = render "/reviews/print", :layout => "print", :locals => {:@review => self, 
                                                                    :@competitors => sorted_competitors, 
                                                                    :@elements => elements, 
                                                                    :@standards => standards, 
                                                                    :@batteries => batteries, 
                                                                    :@css => css, 
                                                                    :@base => base,
                                                                    :@element_scores_chart => element_scores_chart(@mc),
                                                                    :@standard_scores_chart => standard_scores_chart(@mc)}
    @response = DocRaptor.create(:document_content => html, :document_type => "pdf", :test => !Rails.env.production?, :no_subset_fonts => true).body
    s3 = AWS::S3.new :access_key_id => ENV["S3_ACCESS_KEY_ID"], :secret_access_key => ENV["S3_SECRET_ACCESS_KEY"]
    bucket_name = "Testivate" if Rails.env.production?
    bucket_name = "Testivate-staging" if Rails.env.staging?
    bucket_name = "Testivate-localhost" if Rails.env.test? || Rails.env.development?
    bucket = s3.buckets[bucket_name]
    @uploadname = [client_name, "/", product.short_name, "_", Time.now.in_time_zone("Sydney").full_time, "_", SecureRandom.uuid, ".pdf"].join.downcase.gsub(/\W*&\W*|\s+/, "_").gsub("-", "")
    obj = bucket.objects[@uploadname]
    upload = obj.write(@response)    
    obj.acl = :public_read
    client = Googl.client("orders@testivate.com", ENV["GMAIL_PASSWORD"])
    update_attribute :latest_url, client.shorten("http://s3.amazonaws.com/#{bucket_name}/#{@uploadname}").short_url
    NotificationMailer.pdf_creation(self).deliver
  end

And the actual caching occurs in a template?

Yes. Sorry. A snippet:

    - @batteries.each do |battery|
      - cache battery do
        .section{:id => "#{@chapter}"}
          - @chapter += 1
          %h2 Question: &ldquo;#{battery.description}&rdquo;
          %p The website element this question checked: #{battery.element_name}
          %p The quality standard this question checked: #{battery.standard_name}

There's caching elsewhere in the template too. It's necessary as the template builds a 100+ page PDF from 1000s of data points and reams of conditional logic.

Answer 5 · 2013-11-29T21:53:05.000Z

Great, thanks. I'll take a look soon.

Hey robb1e -- any progress on this? Cheers

Answer 7 · 2014-01-22T13:14:52.000Z

Sorry @snoblenet I haven't had a chance. I will try to take a look this week.

Answer 8 · 2014-01-25T14:21:17.000Z

Hi @snoblenet, sorry it's been so long getting back to you. I think I've made a change to fix this. If you update to v0.0.5 hopefully it'll work. I created a small Rails app using 3.2.16 and got the same issue as you, then resolved it with the change. Can you give it a try and let me know how you get on.

Thanks

Answer 9 · 2014-01-26T22:34:17.000Z

Thanks. I've temporarily broken the features that uses render_anywhere on the main branch but as soon as it's working again I'll do this and let you know what happens. Cheers.

Answer 10 · 2014-02-18T09:41:20.000Z

That fixed it for me. Thanks for the update.

Answer 11 · 2014-03-06T18:48:43.000Z

@snoblenet Are you using cache digests? I only ask, because I'm having the same problem, but with a different error thrown from c_d:

 undefined local variable or method `view_cache_dependencies'

Answer 12 · 2014-03-06T21:06:30.000Z

I guess I am using them implicitly in that I'm doing things like:

- cache [@report, element] do

Answer 13 · 2014-03-07T15:38:42.000Z

So then not actually using the cache_digests gem? I might have to fork this and add some includes to get it working.

Answer 14 · 2014-03-07T21:08:31.000Z

Using Rails 4 which I thought bundled the cache_digests functionality that was previously provided through a gem.

Answer 15 · 2014-03-07T21:11:09.000Z

Right your are, still on 3.2.17 on this app here. Thanks for the responses!
