Add custom admin controller and use custom code inside controller

[Serega Sheypak]

Hi!

I'm still in battle with spree. Looks cool but some concepts are not pack into my small brain.

My heroic target is to:

1. Make some custom code (spree-independent). I think I can put it into /lib and then pack as gem (I'm noob in ruby and rails :( )

2. Make custom admin controller with custom UI (simple UI forms usig exisitng taxonomy, prototype UI functionality) and use custom code

Whay did I do:

1. I did read guides. Unfortunately I'm rather dumb and it's not enough for me. i would be glad to share later with some receipts and acquired experience points, but right now I don't know where to start.

2. I've found nice tutorial: http://quickleft.com/blog/how-to-add-a-custom-model-to-your-spree-app

AndI have a question. Where do I have to put ## HOOKS FILE custom_spree_hooks.rb

It's not clear to me. The rest things in article are rather clear. Just reproduce it once and get an idea.

Please help me, I need some details.

My suggestion is to google making a gem for ruby.  With Bundler, it's super easy to install a gem from a git repo and there are plenty of tutorials out there.  If you want to make an extension for Spree, you can just do spree extension 'My-Extension' and it will create the base gem structure for you with the stubbed tie-ins for spree.  I would also take a look at existing extensions to see how to create the admin elements.  Generally, if you write an extension instead of the hooks you'll use Deface to add it.

For instance, in the spree_static_content gem, we add a tab to the admin menu by putting the following code in /app/ovverrides/static_content_admin_tab.rb

Deface::Override.new(:virtual_path => "spree/layouts/admin",
                     :name => "static_content_admin_tab",
                     :insert_bottom => "[data-hook='admin_tabs']",
                     :text => "<%= tab(:pages, :icon => 'icon-file') %>",
                     :disabled => false)

Just make sure you have files ending with _override.rb set to automatically load...

Regards,

Nate

Sorry, I didn't catch your idea.

I did suggest me to create a gem and do not do anyting iside spree app.

Ok, create a gem from git is not a rocket science :)

The snippet you provide raises an exception:

Sorry for early post.

1. I've created my custom contoller:

controllers/spree/admin/parser_controller.rb

class Spree::Admin::ParserController < ApplicationController

  def index

  end

end

2. I've added this snippet to routes.rb

Htdocs::Application.routes.draw do

 mount Spree::Core::Engine, :at => '/'

end

Spree::Core::Engine.routes.prepend do

  namespace :admin do

    resources :parser_controller

    end

end

3. I've created override admin_content_admin_tab_parser.rb

Deface::Override.new(:virtual_path => "spree/layouts/admin",

                     :name => "admin_content_admin_tab_parser",

                     :insert_bottom => "[data-hook='admin_tabs']",

                     :text => "<%= tab :parser, :icon => 'icon-th-large' %>",

                     :disabled => false)

And I get mentioned exception. I don't understand what does it want from me more.

You need to call spree.admin_pages_path, not just admin_pages_path. Or at least, I think so...

Where is PagesController coming from and how are its routes defined?

Ryan,

That's not the issue.  The PagesController doesn't exist in his context.  It exists in spree_static_content which is where I pulled my original snippet from to show him how to do a deface override to add a tab for his controller.  He needed to change the symbol passed to match his controller.  I didn't make it clear what he needed to modify to make it work, hence the path error.

Serega,

A few things.

1. I am pretty sure that your controller needs to be pluralized.  It should be ParsersController located in file parsers_controller.rb.  
2. ParsersController should inherit from Spree::Admin::ResourceController instead of ApplicationController.  This gives you access to the restful route helpers available.
3. Your route for the ParsersController is wrong.  It needs to be
   

   namespace :admin do
       resources :parsers
     end

4. Your Deface override is wrong.  You need to use the plural form.  Change the text variable to: "<%= tab :parsers %>"
5. Once you fix #1-3, the routes error should go away.  If it does not, you can always manually specify the path by setting the Deface text to: "<%= tab :parsers, :url => spree.admin_parsers_path %>"

Regards,

Nate

If it's a Spree specific controller, it should be prepended to Spree::Core::Engine.routes. Do you have a basic application that you can share which reproduces this problem?

Here is controller code:

module Spree

  module Admin

    #class ParsersController < Spree::Admin::BaseController

    class ParsersController <  Spree::Admin::ResourceController

      def index

        @parser = Spree::Parser.new

WTF man??? Yesterday it was working!!!

Ok. Let's try some magic bro. Looks like something undescribable.

I did comment a line in controller:

#@parser = Spree::Parser.new

Let's try to refresh page and get expected exception:

Okay, no problem. My view code tries to pull some model methods from nil.

Again magic: uncomment a line of code and try to refresh page:

@parser = Spree::Parser.new

Wow, it works :))))

I'll do my best to prevent it.

The problem is caused by this line within your Parser model (which the console logs actually point to):

    belongs_to :taxon, :prototype

You must define different belongs_to associations on separate lines:

    belongs_to :taxon

    belongs_to :prototype

[Serega Sheypak]

I've already did it and it helped.

Then I turned off computer, started it next day and got mistary exception.

The model was ok at that time.
