Does anyone know of a good tutorial for installing Authlogic in Rails 3? I know how to generate the files and everything, I just keep getting errors.

Has anyone here done this yet?

for reference I followed: http://github.com/binarylogic/authlogic_example

I've begun using devise with omniauth and I cannot get my localhost machine recognized by my facebook app settings. The error message I get is:

"error": {
"type": "OAuthException",
"message": "Invalid redirect_uri: Given URL is not allowed by the Application configuration."

I've read that changing my hosts file can fix this, but it has not worked for me. Does anyone know how I can get facebook to recognized a localhost machine? I'm going to keep trying because this is driving me insane.

Edit: My changes worked, sanity restored.

This was covered a few pages ago, but I cannot find it.

Do you guys have suggestions for hosting, preferably some kind of reseller hosting? I'll have a few client sites going up soon, and I need a host that is rails 3.0 compatible. Possibly a goon hosting solution?

I'm at my wits end, or maybe I'm too tired.

This is my first time using carrierwave, and for some reason I am having a hell of a time getting lightwindow to work correctly with it. (or any lightbox for that matter)

code:

<%= lightwindow_link_to(
	image_tag(artwork.image_url(:thumb)), artwork.image_url(:large), 
        :title => "This is a test!",
	:author=>"Carlo Bertini",
	:caption=>"Ruby on rails is beautyfull :D",
) %>

I have it all connected properly, however the url returned from artwork.image_url(:large) has a trailing / resulting in a lightwindow with a string in it.

How can I remove the trailing /, or is there a better solution for my lightbox needs?

Edit: Figured it out. The lightwindow plugin must be depreciated.

Thanks, but I decided to go with topup since it seems to have better documentation.

I have a new problem now, and it's about using kaminari for pagination.

My app is basically a simple photo gallery, and although I have pagination working for the gallery index method, I need to limit how many images are displayed using the show method as well.

It looks like this.

code:

class GalleriesController < ApplicationController
  def index
    @galleries = Gallery.page(params[:page]).per(5)
  end

  def show
    @gallery = Gallery.find(params[:id])
  end

.
.
.

end

What do I need to insert into the controller or model in order to limit the number of images found in a gallery?

I can provide more code if necessary.

Argh, I still don't get it. Here is some more information, hopefully someone can show me what I am doing wrong.

controller :

code:

class GalleriesController < ApplicationController
  # GET /galleries
  # GET /galleries.json
  def index
    @galleries = Gallery.page(params[:page]).per(4)

    respond_to do |format|
      format.html # index.html.erb
      format.json { render json: @galleries }
    end
  end

  # GET /galleries/1
  # GET /galleries/1.json
  def show
    @gallery = Gallery.find(params[:id])
    @gallery.photos.page(:pagina).per(2)
    
    respond_to do |format|
      format.html # show.html.erb
      format.json { render json: @gallery }
    end
  end

index view:

code:


<% @galleries.each do |gallery| %>
  <tr>
    <td><%= gallery.name %></td>
    <td><%= link_to 'Show', gallery %></td>
    <td><%= link_to 'Edit', edit_gallery_path(gallery) %></td>
    <td><%= link_to 'Destroy', gallery, confirm: 'Are you sure?', method: :delete %></td>
  </tr>
<% end %>
</table>

<%= paginate @galleries %>  <-- THIS WORKS

show view:

code:


<h2>Photos</h2>
<% @gallery.photos.each do |photo| %>
  <p>
    <b>title:</b>
    <%= photo.title %>
  </p>
	<%= image_tag photo.photo_url(:thumb) if photo.photo? %>
<% end %>

<%= paginate @gallery %>  <--- THIS PRODUCES UNDEFINED METHODE 'CURRENT_PAGE'

I recreated a really simple version to just play with this, and I still have no luck. As before I have pagination working on my index view, however I cannot get it working on my show view.

How would I use kaminari to paginate the photos in the show view?

I'm starting to learn about polymorphic associations, and have run into a road block of sorts. So far I have followed and understood the basic concepts presented by ryan baits in episode #154, and have even created the same basic app. I can create new comments, and destroy, however I cannot figure out how to edit them.

I understand that I should be using edit_polymorphic_path or edit_polymorphic_url, and am even 99% sure I am passing in the right models. However when I click the link I get a hash error, which may suggest something is wrong with my controller.

so... does anyone have a working example or know of one that shows a complete polymorphic association in action? My final goal is to create a polymorphic image model with carrierwave, but cannot find many working examples.

Or should I avoid using polymorphic associations all together?

I'll be looking at adding a cart to an existing clients site, and I would appreciate some feed back regarding spree. If I need a highly customized look, is spree simple enough to bend to my will? I took a look at the documentation, and they recommended against replacing the entire theme manually due to issues caused by future upgrades.

Also, is there anything else I should be looking at in terms of rails e-commerce. Spree seems to offer what the client wants, but I am eager to learn how to do this myself. Considering time is not an issue, are there some good (current) resources regarding creating your own simple(?) carts?

To clarify this is for an artists site, and all they really want to do is sell prints from their online portfolio. Ideally it would be nice to have the option of adding pieces to a store when they are uploaded to the portfolio, and define print size, prices, etc. all at the same time.

I need to be schooled in e-commerce please.

When using postgresql in a new app it won't allow me to connect unless I specify a host:

code:
database.yml development: adapter: postgresql encoding: unicode database: *** pool: 5 host: localhost <-- username: *** password: ***
Using my previous setup I never had to include that option, what happened?

Edit: It was a pathing issue. Once I corrected the path in .bash_profile and reinstalled the pg gem it is working as expected again.

What's really bothering me is the inability to play with Rails Apps Composer, since the active record recipe doesn't allow me to provide the username / password / host options. It simply tries using the default rails database.yml, which results in the script being unable to access the db.

While I'm at it, how do people feel about Rails Apps Composer, or Rails Wizard? Are they a good idea to use for basic app templates? Or would you rather stick to the manual approach of setting up a new app?

I'm really interested to know why you think this. I've used Heroku for a little while now, and set-up is nearly painless. My only complaint is the price associated with it. The bare minimum (after the free tier) is $35.00 a month + whatever add-ons you want to use.

I have recently experimented with a VPS or two, and although I got it running properly, it took time (which could have been spent working on the app). At this point I'm comfortable setting up a new server with rvm-capybara + nginx + unicorn, but my god was the documentation to do so fragmented. The cost however is much lower.
