[The docs explain what `:cascade` does][1]:

&gt; `:force` - Set to `:cascade` to drop dependent objects as well. Defaults to `false`.

One reason you may be seeing this is a change in Rails 4.2 in `SchemaDumper` to use `:cascade`, [release notes][2].

Release notes about change:
&gt; `SchemaDumper` uses `force: :cascade` on `create_table`. This makes it possible to reload a schema when foreign keys are in place.

http://api.rubyonrails.org/classes/ActiveRecord/ConnectionAdapters/SchemaStatements.html#method-i-create_table

:force
Set to ```true``` to drop the table before creating it. Set to ```:cascade``` to drop dependent objects as well. Defaults to ```false```.



Need to confirm something. The following code:

    CompletableFuture
        .supplyAsync(() -&gt; {return doSomethingAndReturnA();})
        .thenApply(a -&gt; convertToB(a));

would be the same as:

    CompletableFuture
        .supplyAsync(() -&gt; {
            A a = doSomethingAndReturnA();
            convertToB(a);
     });

Right? 

Furthermore, another two questions following as for &quot;is there any reason why we would use `thenApply`?&quot;

1) having big code for conversion? 

**or**

2)  need to reuse the lambda block in other places?

CompletableFuture, supplyAsync() and thenApply()

If I define a function

    inc = function(x) { return x + 1 }

and make a nested invocation of it

    inc(inc(inc(inc(inc(inc(inc(inc(inc(inc(inc(inc(inc(inc(inc(inc(inc(inc(inc(inc(inc(1)))))))))))))))))))))

this will result in the value `22`. If I revise the nested expression to instead make use of `call`, passing in `null` for `this`, as

    inc.call(null, inc.call(null, inc.call(null, inc.call(null, inc.call(null, inc.call(null, inc.call(null, inc.call(null, inc.call(null, inc.call(null, inc.call(null, inc.call(null, inc.call(null, inc.call(null, inc.call(null, inc.call(null, inc.call(null, inc.call(null, inc.call(null, inc.call(null, inc.call(null, 1)))))))))))))))))))))

this will also produce the value `22`. 

But, on JavaScriptCore this second form appears to consume _O_(2^_n_) memory, where _n_ is the number of nested calls. This is not the case if I try this JavaScript in Firefox or Chrome so it seems to be isolated to JavaScriptCore.

I have very little JavaScript experience (almost none). I don&#39;t have a feel for the tradeoffs that various JavaScript implementations might make, nor whether it is reasonable for the example code to be expensive in some implementations (providing generic support for closures or some such), while efficient in others.

My question is: Is this code inherently problematic? Should it be rewritten to be structured in a different way? Or is the code fine—does JavaScriptCore simply have a bug? 

I&#39;ve done some experimentation where refactoring a few of the inner calls to temporaries will &quot;truncate&quot; the memory doubling behavior

    var temp1 = inc.call(null, inc.call(null, inc.call(null, inc.call(null, inc.call(null, inc.call(null, inc.call(null, 1)))))));
                                                                                                  
    var temp2 = inc.call(null, inc.call(null, inc.call(null, inc.call(null, inc.call(null, inc.call(null, inc.call(null, temp1)))))));
        
    inc.call(null, inc.call(null, inc.call(null, inc.call(null, inc.call(null, inc.call(null, inc.call(null, temp2)))))));

JavaScriptCore nested &quot;call&quot; performance issue

After adding another migration and occasional decision to drop and migrate I checked my schema.rb
and saw this

    create_table &quot;users&quot;, force: :cascade do |t|

I haven&#39;t committed this changes yet and on remote I have this

    create_table &quot;users&quot;, force: true do |t|


Now I have cascade in front of each table. What is cascade and where did it come from?

What is :cascade in rails schema.rb and where did it come from?

I was trying to select objects uniq by one attribute, using `@videos.uniq{|p| p.author}`

      time = Time.new(2014, 12)
      start_time = time.beginning_of_month
      end_time = time.end_of_month

      videos = Video.where(&quot;created_at &gt; ? AND created_at &lt; ?&quot;, start_time, end_time).where(&quot;likes &gt; ?&quot;, 15)
      selected_videos = videos.uniq{|p| p.author}
      puts videos.count, videos.class, selected_videos.count 
     #=&gt; 23, Video::ActiveRecord_Relation, 23
    
      videos_first = videos.first(23)
      selected_videos = videos_first.uniq{|p| p.author}
      puts videos_first.count, videos_first.class, selected_videos.count
      #=&gt; 23, array, 10

`.uniq` is not for `ActiveRecord_Relation`. And the problem is that the query returns a `Video::ActiveRecord_Relation`, but I need `array`.

Certainly, this could be achieved by using `to_a`, but is this elegant? 

1. What&#39;s the correct way of handling this ?
2. Is it possible to use `.uniq` for `activerecord:relation`?

Rails: correct way of turning activerecord relation to array?

I have the following two Models:

    class Store &lt; ActiveRecord::Base
        belongs_to :person
    end

    class Person &lt; ActiveRecord::Base
        has_one :store
    end


Here is the issue: I am trying to create a migration to create the foreign key within the people table. However, the column referring to the foreign key of Store is not named *store_id* as would be rails convention but is instead named *foo_bar_store_id*.  

If I was following the rails convention I would do the migration like this:

    class AddReferencesToPeople &lt; ActiveRecord::Migration
      def change
        add_reference :people, :store, index: true
      end
    end

However this will not work because the column name is not ***store_id*** but is ***foo_bar_store_id***.  So how do I specify that the foreign key name is just different, but still maintain index: true to maintain fast performance?

Rails Migration: add_reference to Table but Different Column Name For Foreign Key Than Rails Convention

Before writing this question I looked at these answers, but was unable to find a solution.: 

[Error when execute rails generate scaffold User name:string email:string][1]

[Error launching Rails server: undefined method &#39;configure&#39;][3] 


----------


When I try to start a new application (for  [Hartl&#39;s tutorial][4], Chapter 2), at the stage *scaffold* start, I got an error like: 

    **undefined method `configure&#39; for #&lt;SampleApp2::Application:0x00000101a74610&gt; (NoMethodError)**

But thanks to the above examples, I edited the *development.rb* file:

    DemoApp::Application.configure do
(Yes, my application is called *demo_app* so I transformed its name).

After that, I tried to run *scaffold* again but got a new error:

    **method_missing&#39;: undefined method raise_in_transactional_callbacks=&#39; for ActiveRecord::Base:Class (NoMethodError)**

In response to similar cases indicates a *migration* method - that it should be removed from the file development.rb. Similarly, I tried to find in this file *raise_in_transactional_callbacks* method, but it&#39;s not there!
In addition, I would say that the full code that produces in cmd is very large:

    C:\Sites\demo_app&gt;rails generate scaffold User name:string email:string

Where the ...(ellipsis) - specially cut similar code.
That&#39;s all. I would be grateful for any help!

I also downgraded the turbolinks gem from 2.3.0 to 2.2.2, thinking that the newer version of the turbolinks gem was causing my app to have errors; obviously that didn&#39;t work for me.

Any suggestions on what could be going wrong with my app?
