  • State changed from “new” to “open”

  This is really strange. If I can get this to work properly I can solve the issue. Any ideas?

  >> User.send(:merge_joins, "one", "two")
  => ["one", "two"]
  >> User.respond_to?(:merge_joins)
  => false
  

  That should return true.

  I got this fixed, apparently ActiveRecord changes the default behavior of respond_to?, the second option allows you to include private methods.

  Anyways, this should be fixed now.

  For me it seems the bug is still there. I have tested your latest commit with the rails-settings plugin, which includes this "method_missing":

  class Settings < ActiveRecord::Base
    ....
  
    def self.method_missing(method, *args)
      method_name = method.to_s
      super(method, *args)
  
    rescue NoMethodError
      #set a value for a variable
      if method_name =~ /=$/
        var_name = method_name.gsub('=', '')
        value = args.first
        self[var_name] = value
  
      #retrieve a value
      else
        self[method_name]
  
      end
    end
  

  Perhaps this code smells, because the model "Settings" responds to everything, but didn't define a "respond_to?" method.

  I don't know if it's worth to fix compatibility issues regarding every plugin. But because this plugin works without searchgasm (and not with searchgasm), I think this can be cause other plugins to fail.

  Are you sure you are using the latest searchgasm?

  I just ran some tests:

  >> Settings.awesome
  => nil
  

  And it works fine. What rails version are you using?

  Strange, you are right, it works fine with plain Rails (2.1.1) and just this plugin (tested with new created Rails app). In my existing application there are a some more plugins in use. I will do some further tests to see which combination of plugins breaks it.

  After a few hours of debugging I give up :( In a plain new Rails app the StackOverflow does not occur, but in my large application it does (on calling "Settings.foo"). I have copied all plugins, gems, initializers and same more to the plain app, but in this dummy app it all works. I can't extract the problem.

  I will come back later to this ticket if I can reproduce it...

  I am certain I could easily fix the issue. I am betting it has to do with your version of ActiveRecord. Are you using the same version of rails?

  I want to solve the problem because something isn't right. I am leaving ot go on vacation and will return Sunday. If you have skype or anything, maybe we can get together on that and try to debug it together. I am certain we can solve the issue quickly. Something like this, where I can't reproduce the problem, would take forever talking through this.

  What was the problem before we the add_joins method in searchgasm/active_record/base.rb. That function was calling a method that didn't exist, which then called method_missing in Settings.rb. Settings.rb called add_joins again, and it got caught in an infinit loop. Settings.rb called add_joins becuase it is trying to execute a query. I have a feeling the problem lies somewhere in add_joins. Also, add_joins is just copied over from ActiveRecord with my own modifications. You will notice there are 2 versions and I do checks to determine which version of code to run. Since add_joins has changed quite a bit in the last few versions of rails.

  Argh, shame on me, it was my fault:

  I made some modifications to the plugin "rails-settings" (including renamings of the database fields) and replaced the plugin (by mistake) with the original from github, so the method "Settings.find_by_var" did not work anymore because of the missing field "var" in the database. So the method_missing was called in an endless loop. It has nothing to to with searchgasm (except I made this nearly the same time I upgraded searchgasm).

  In my dummy app the original plugin and original database structure were matching, so all went fine in this app.

  Thank you for your commitment, I hope my future bug reports will not be such false alarm ;-)

  Note to myself: Never ever change plugins from other people without creating a fork on github.

  Not a problem at all, glad you figured out what the issue was. Let me know if you have any other problems.
