Edit: Also, is the method private maybe? I would imagine Rails should throw an error if that happens but many things in Rails don't happen the way I imagine.

Nope, it's public, but that got me fooling around a little more. On a whim, I renamed my "display" action to "enlarge", updated the routes and all the other references, and it works now!

What I didn't realize at the time is that Ruby already has an Object#display method, which I would have to guess is what caused the problem. A lot of trouble for nothing, apparently.

The TinyMCE ~/vendor/plugin folder seems to come with basically the same folders it puts in the ~/public directory. Is it safe to delete anything out of there? It slows down and usually times out FTP and SVN transfers.

I'll rename it "enlarge", so we stop getting hung up on the synonym and overlooking the actually problem here, which is why an action method isn't getting called.

You know what, that would fix it. "display" is a preexisting method in ActionController.

Edit: Oh, there was a new page I didn't see and you found that out already. Awesome.

Having a weird problem with drag & drop sortable lists--

I have two lists, one of categories and one of pages, with the following code:

code:

#controller
def update_category_sort_order
  	  params[:sortable_category_list].each_with_index do |id, category_order|
    	Category.update(id, :category_order => category_order)
  	  end
 	  render :nothing => true
  end

def update_page_sort_order
  	  params[:sortable_page_list].each_with_index do |id, page_order|
    	Page.update(id, :page_order => page_order)
  	  end
 	  render :nothing => true
  end


#view

#list_categories
<ul id="sortable_category_list">
<% @categories.each do |category| %>
<li id="item_<%= category.id %>"><%= category.title %></li>
	<% end -%>
</ul>

<%= sortable_element 'sortable_category_list', 
:complete => visual_effect(:highlight, 'sortable_category_list'), 
:url => { :action => "update_category_sort_order" } %>

/*-----------------------*/

#list_pages
<ul id="sortable_page_list">
<% @pages.each do |page| -%>
	<li id="item_<%= page.id %>"><%= page.title %></li>
<% end -%>
</ul>

<%= sortable_element 'sortable_page_list', 
:complete => visual_effect(:highlight, 'sortable_page_list'),
:url => { :action => "update_page_sort_order" } %>

It works PERFECT. I drag and drop my categories around and the order is updated in the db.
BUT when I drag and drop my pages around, the UI changes, but the DB is not updated.

This happens in my development.log:

code:

(various line breaks added to fix table breakage)

As you can see, the UPDATE command is missing for the pages section, and it's instead doing some weird select where clause that says id <> 6 or 7 depending on the id

I have an Entries model and I have a Votes model. Each Entry has many Votes and each time that an Entry is loaded, the associated Votes will also need to be loaded, is there a way I can use scope to automatically :include => :votes on each request?

Or is this not good practice?

In Edge rails, there's now default scoping: http://ryandaigle.com/articles/2008/11/18/what-s-new-in-edge-rails-default-scoping

Although if you aren't running Edge, you might want to just create a named_scope that does it, and just make sure you always use that named_scope when accessing your entries.

Honestly, it's not good practice.

Evil Trout's suggestion is better though. I think it's pretty important to be able to see the eager loaded tables (or at least scopes that suggest something funny's going on) at first glance for every ActiveRecord find call.

code:

class Entry
  has_many :votes
  named_scope :with_votes, :include => :votes

code:

Entry.with_votes.all :order => "created_at DESC", :limit => 10

If I am correctly inferring what you are trying to do, you might want to reconsider your use of GET.

Edit: I think this is a little nicer to read, also.

code:

<span class="activation-link">
  <% link_to category_path(category, :active => !category.active?), :method => :put do %>
    <%= category.active? ? 'Deactivate' : 'Activate' %>
  <% end %>

Nolgthorn: Jan 30, 2001; The pendulum of the mind alternates between sense and nonsense

Thanks for the advice, I am using named_scope now.

I have some restful routes in my application, shorthand it looks like this.

code:

  map.resources :entries
  map.root :controller => 'entries'

Now in my application if I call entries_path the result is a link to /entries when what I really want is to go to / instead. The path /entries should never really come up unless I've specified a entry_id, is there a way for me to tell Rails that the shorter url takes priority?

Before I started using rest Rails was good at picking the shortest url because I would always put the shorter urls lowest in the order.

Or do I have to start explicitly using root_path instead?

Yeah we'll see how it goes. If it ends up being the best of the two, that'll be great.

From what I've talked to people, Rails is going to be like Merb, where the default stack is just going to be the current Rails stack. But you could swap out AR for datamapper, or you could easily switch to jquery without extra plugins like you need today.

For rails, they get some smart people on the team from merb, and don't have to worry about merb killing them. For merb, they get, what, name recognition? I don't really see how this move helps the merb team.

I'm all in favor of choice, but since I already had that with Merb, I don't really gain anything.

I'm not sure why this is good for Merb, either. I, personally, didn't see the competition between the two frameworks as a bad thing.

It might actually benefit to start learning Merb. It'll get you prepared for Rails 3, which, after reading more, might be very heavily impacted by the Merb merge.

Overall, this seems like it is great for Rails people and "Meh?" for Merb people. I haven't seen a Merb person (aside from the Core team) who is particularly excited about this.

I am definitely including prototype, because the alert("hello world") works, and the log shows the action being called from the controller, with the correct parameters. For some reason page.show 'products' isn't working.

Also, I'm still a big time noob so I'm not using named routes because I'm not even sure what you mean.

I mean, I know how to look it up and figure it out, but it's going to take time, it's not what I'm used to (I started on the tutorials for 1.2)

I figured it out. It can't overwrite my CSS (display:none;) So I need to hide it with prototype on load, too. No big.

Now my problem is I have If conditionals powering which DIV element to show depending on what's selected. According to my log, my parameter is :entry_type_id so I would think this would work:

code:

page.show 'products' if params[:entry_type_id] == 1

But it doesn't. I'm sure it's a dumbass noob move, but I learn every time I do something dumb, so whatever.

I, personally, didn't see the competition between the two frameworks as a bad thing.

I do not see the benefit of continuing the separation between projects. As I read it, Merb will become Rails-core. Rails-flat will implement Rails on top of Merb, so to speak. The philosophies of both projects should remain, while eliminating the duplication of efforts.

Competition helps in business because there is a benefit to having more customers than the next guy. There is no real benefit to having more "customers" than the other guy when your product is free, and freely available to be modified.

It might actually benefit to start learning Merb. It'll get you prepared for Rails 3, which, after reading more, might be very heavily impacted by the Merb merge.

My plan is basically to keep on top of edge, and keep the apps I work on up-to-date with the changes.

Overall, this seems like it is great for Rails people and "Meh?" for Merb people. I haven't seen a Merb person (aside from the Core team) who is particularly excited about this.

It's validation that they were right about their architecture

I am using attachment_fu with ImageMagick/RMagick and I have this code in my photo model:

code:

class Photo < ActiveRecord::Base
	has_attachment 	:content_type => :image, 
                 	:storage => :file_system, 
                 	:max_size => 1.megabyte,
                 	:resize_to => '700x466>',
                 	:thumbnails => { 
                 		:thumb => '150x150>',
                 		:cropped => '70x70!' }
					
	validates_as_attachment
end

I have the same exact code in my model on my production server and it makes proper 70x70 cropped thumbnails. But on my local copy (both using rails 2.1), the cropped version is just a resize, and it distorts the picture. Anyone have any ideas? I did rewrite the application on my local copy, but I copied this model exactly.

Fairly certain that attachment_fu still doesn't support cropping due to the vast differences between the many image processors out there. You may have a modified version of the plugin that is only designed to work with some processors and may be running on a different one by default in production.

Try this:

code:

class Photo < ActiveRecord::Base
	has_attachment 	:content_type => :image, 
                 	:storage => :file_system, 
                 	:max_size => 1.megabyte,
                 	:resize_to => '700x466>',
                 	:thumbnails => { 
                 		:thumb => '150x150>',
                 		:cropped => '70x70!',
                        :processor => :rmagick }
					
	validates_as_attachment
end

Merry Christmas!

This is by far the best article on Rails 3 Merb/Rails merge, or Why should merbists be happy?, and it's answered all of the questions I had about what was in it for merb.

I'm pretty excited now. What I'd like to see most, I think, is a big step forward from each framework. Even if it will break a lot of existing stuff and plugins. Sorta like the difference between os 9 and X.

If there's going to be a clean merb-style API, there could maybe be some sort of transition API on top of that to ease old apps into Rails 3, whereas new apps wouldn't need it.

Why is it important to maintain any semblance of plugin backwards-compatibility? Generally if you're developing a Rails application, you use the latest version and go to production when it's done using whatever version you started with, unless there is a feature you absolutely need you wouldn't update it.

I would imagine there is a lot of code that could be different or that is different in Merb, why keep all these old methods? Isn't that all the opposite of trimming down the bloat Rails has been accumulating and the opposite of making it run faster?

Edit: Ohhh they're just talking about a public API for plugin functionality... ok I guess.

I really hope they bring Merb's slices.

The exact same plugin, image processor and model/code works on my other copy of the application though.

Example:

On my production server:

On my local copy:

The only difference is on my production copy I'm doing 75x75! instead of 70x70! Everything else is the same: model/code, plugin, img processor. The production copy STARTED on my local box and worked then, too.

I still think you would benefit by specifying the image processor you want if you're going to be using cropping.

It did not help. I don't know what's up with it. Really sucks though because his thumbnails look like crap and that's no good for a photography portfolio.

I have been working on a Rails contract for the past year but it's coming to an end in January and there are no other local jobs. What are you guys doing for work? Where are places to look for work online?

That's fine for applications that have active maintainers. For applications that don't, and need to stay in lock-step with security updates to the platform, breaking everything possible on a new release is kind of nightmarish for system administrators, who might have the good sense and Ruby knowledge to migrate small apps to the new framework, but have no interest in completely rewriting all plugin-provided functionality. Rails doesn't exactly have the best track record of backporting security fixes to prior releases once a new one is out.

UGH, I realized what it is. I looked up how to do cropped thumbnails with attachment_fu/rmagick, and I remembered I found this, which makes you rewrite the processor code:
