# Returns corresponding model class for this controller
# @return [ActiveRecord::Base]
def corresponding_model_class

DISCLAIMER: Scaffolding is not recommended unless it's for very conventional CRUD apps/testing. This may generate a lot of files(views/models/controllers) that are not needed in your web application thus causing headaches(bad :().
To generate a fully working scaffold for a new object, including mod...
console.count([obj]) places a counter on the object's value provided as argument. Each time this method is invoked, the counter is increased (with the exception of the empty string ''). A label together with a number is displayed in the debugging console according to the following format:
[label]: ...
Debug.log's second argument is always returned, so you could write code like the following and it would just work:
update : Msg -> Model -> (Model, Cmd Msg)
update msg model =
case Debug.log "The Message" msg of

Replacing case msg o...

The Java language provides 4 operators that perform bitwise or logical operations on integer or boolean operands.
The complement (~) operator is a unary operator that performs a bitwise or logical inversion of the bits of one operand; see JLS 15.15.5..

Easily add a heading container to your panel with .panel-heading. You may also include any <h1>-<h6> with a .panel-title class to add a pre-styled heading. However, the font sizes of <h1>-<h6> are overridden by .panel-heading.
For proper link coloring, be sure to place links...
Wrap buttons or secondary text in .panel-footer. Note that panel footers do not inherit colors and borders when using contextual variations as they are not meant to be in the foreground.
<div class="panel panel-default">

Content scripts can be declared in manifest.json to be always injected into pages that match a set of URL patterns.
Minimal example
"content_scripts" : [
{
"js": ["content.js"],
"css": ["content.css"]
"matches": ["...
If, instead of always having a content script injected based on the URL, you want to directly control when a content script is injected, you can use Programmatic Injection.
Minimal example
JavaScript
chrome.tabs.executeScript({file: "content.js"});
CSS
chrome.tabs.insert...
Same conditions, multiple scripts
If you need to inject multiple files with all other conditions being the same, for example to include a library, you can list all of them in the "js" array:
"content_scripts" : [
{
"js": ["library.js", "conten...
There are two basic styles of type conversion in Go:
// Simple type conversion
var x := Foo{} // x is of type Foo
var y := (Bar)Foo // y is of type Bar, unless Foo cannot be cast to Bar, then compile-time error occurs.
// Extended type conversion
var z,ok := x.(Bar) // z is of type Bar, o...
As Go uses implicit interface implementation, you will not get a compile-time error if your struct does not implement an interface you had intended to implement. You can test the implementation explicitly using type casting:
type MyInterface interface {
Thing()
}
type MyImplementer struct {}
