Yes, this is a pluralization error.

By passing the ID 1, I assume that you wish to display a single record.

So you need to use the singular &#39;message_thread&#39;:

    message_thread_path(1)

Which will yield:

    http://localhost:3000/message_threads/1

Sometimes this also is when you don&#39;t provide an :as parameter in your route:

    delete &quot;delete/:id&quot; =&gt; &quot;home#delete&quot;

Changed to:

    delete &quot;delete/:id&quot; =&gt; &quot;home#delete&quot;, as: :delete

(ignore the odd example, just happened to be something we just ran into for an internal app we&#39;re building)

Other folks that land here might be in this situation:

If you have a singular resource declared in your `routes.rb`:

```ruby
resource :map
```

You don&#39;t need to pass an object to `map_path`. Attempting to call `map_path(map)` will result in similar behavior (i.e. a URL like `map.12`).



I am trying to download a tarball from GitHub using [cURL][1], but it does not seem to be redirecting:

    $ curl --insecure https://github.com/pinard/Pymacs/tarball/v0.24-beta2
    &lt;html&gt;&lt;body&gt;You are being &lt;a href=&quot;https://nodeload.github.com/pinard/Pymacs/tarball/v0.24-beta2&quot;&gt;redirected&lt;/a&gt;.&lt;/body&gt;&lt;/html&gt;

Note: wget works for me:

    $ wget --no-check-certificate https://github.com/pinard/Pymacs/tarball/v0.24-beta2

However I want to use cURL because ultimately I want to untar it inline with something like:

    $ curl --insecure https://github.com/pinard/Pymacs/tarball/v0.24-beta2 | tar zx

I found that the URL after redirecting turned out to be https://download.github.com/pinard-Pymacs-v0.24-beta1-0-gcebc80b.tar.gz, but I would like cURL to be smart enough to figure this out.

What is the difference between filter with multiple arguments and chain filter in django?

In my routes.rb I have the following:

    resources :message_threads

When I call:

    message_threads_path(1)

I get:

    /message_threads.1

Why is this? My other resources work fine. Am I not pluralizing this correctly or something?

Path helpers generate paths with dots instead of slashes

In my routes.rb I have the following:
<pre><code class="hljs language-ruby">resources :message_threads

When I call:

I get:
<pre><code class="hljs language-bash">/message_threads.1

I have a table in a Rails application which (in schema.rb) looks like:

    create_table &quot;users&quot;, :force =&gt; true do |t|
       t.string &quot;name&quot;, :null=&gt;false
       t.string &quot;address&quot;, :null=&gt;false
    end

I would like to write a rails migration to allow nulls for the address field. i.e. after the migration the table looks like this:

    create_table &quot;users&quot;, :force =&gt; true do |t|
       t.string &quot;name&quot;, :null=&gt;false
       t.string &quot;address&quot;
    end

What do I need to do to remove the constraint?

Build-in rake tasks work fine, but my new custom one, in Project/lib/tasks/payments.rb doesn&#39;t get loaded:

    namespace :payments  do
      desc &quot;Tally payments at the end of the month&quot;
      task :compute =&gt; :environment do
        BillingPeriod.compute_new_period
      end
    end

    $ rake payments:compute
    (in /Users/rob/Code/Apps/skyfarm)
    rake aborted!
    Don&#39;t know how to build task &#39;payments:compute&#39;

It works fine if I load the file application.rb:

    require &#39;lib/tasks/payments.rb&#39;

...but it breaks other things:

    $ rails s
    ./lib/tasks/payments.rb:1: undefined method `namespace&#39; for main:Object (NoMethodError)




Why is my custom rake task in lib/tasks not discovered in Rails 3?

I have a model A that has a &quot;has_many&quot; association to another model B.  I have a business requirement that an insert into A requires at least 1 associated record to B.  Is there a method I can call to make sure this is true, or do I need to write a custom validation?

Right now I&#39;m using this which works for the development host, but I have to manually change the {:host =&gt; &quot;&quot;} code when I move to production.

### post.rb

    def share_all
      url =  Rails.application.routes.url_helpers.post_url(self, :host =&gt; &#39;localhost:3000&#39;)
      if user.authentications.where(:provider =&gt; &#39;twitter&#39;).any?
        user.twitter_share(url)  
      end
    end

I&#39;d like to use this and then define the default_url_options per environment:

### post.rb

    def share_all
      url =  Rails.application.routes.url_helpers.post_url(self)
      if user.authentications.where(:provider =&gt; &#39;twitter&#39;).any?
        user.twitter_share(url)  
      end
    end


I&#39;ve tried adding this to my config/environments/development.rb but I still get the &quot;Missing host to link to! Please provide :host parameter or set default_url_options[:host]&quot; error 

### development.rb

    config.action_controller.default_url_options = {:host =&gt; &quot;localhost:3000&quot;}


And I even tried it this way:

### development.rb 
    config.action_controller.default_url_options = {:host =&gt; &quot;localhost&quot;, :port =&gt; &quot;3000&quot;}



EDIT:

I&#39;ve now also followed this and still the same error guide http://edgeguides.rubyonrails.org/action_controller_overview.html#default_url_options

### application controller

    class ApplicationController &lt; ActionController::Base
      protect_from_forgery
      include ApplicationHelper
      def default_url_options
        if Rails.env.production?
          { :host =&gt; &quot;example.com&quot;}
        else
          {:host =&gt; &quot;example1.com&quot;}
        end
      end
    end

This is driving me crazy, what am I missing here???

How to set config.action_controller.default_url_options = {:host = &#39;#&#39;&#39;} on per environment basis

Does rails make any guarantees about the order that before filters get executed with either of the following usages: 

    before_filter [:fn1, :fn2]

or 

    before_filter :fn1
    before_filter :fn2

I&#39;d appreciate any help. 

How can I specify the order that before_filters are executed?

How can I run a command five times in a row?

How can I run a command five times using Ruby?

in my rails app I&#39;m creating an array like so:

    @messages.each do |message|

      @list &lt;&lt; {
        :id =&gt; message.id,
        :title =&gt; message.title,
        :time_ago =&gt; message.replies.first.created_at
      }
    end

After making this array I would like to then sort it by time_ago ASC order, is that possible?
