Web Application Development with Beego
======================================

Beego is a fantastic web application framework from the Go China
community. It currently powers some of the biggest websites in China,
and thus the world.

Let's get started. For now I am going to assume you are running OSX or
Linux. Getting Beego set up on Windows with the sqlite driver is
nontrivial at best due to Windows being terrible.

### Installing Beego 

The Beego developers have made a tool called bee for easier managing of
Beego projects. To install it, run:

```
go get github.com/beego/bee
go get github.com/astaxie/beego
```

The `bee` tool will be present in `$GOPATH/bin`. Please make sure this
folder is in your `$PATH` or things will not work.

### Creating a Project 

Navigate to a directory in your `$GOPATH` and run the command `bee new
quickstart`:

The `bee` tool created all the scaffolding we needed for our example
program. Change into that directory and run `bee run`. Your
application will be served on port 8080.

Now let's take a look at the parts of Beego that are in use. Beego is a
typical MVC style framework so there are 3 basic places you may need to
edit code:

The Models are Beego's powerful database-backed models (we'll get into
those in a little bit), the Views are normal Go
[html/template](https://godoc.org/html/template)s, and 
the Controllers are the Go code that controls the Views based on the Models.

New Beego projects use Beego's default HTTP router, which is similar to
Sinatra or Tornado. The default router is very simple. It will only
route `/` to the MainController that was generated for you:

The main file will shadow-include the router package which will seed the
Beego router with your paths and site content. The MainController will
embed beego.Controller so it acquires all instance methods that a Beego
controller needs. Beego's controllers offer many methods that could be
used based on different HTTP verbs, but this simple example only
overrides the GET verb to serve the site. The data that will be passed
to the template is a `map[string]interface{}` as c.Data. The last line
tells Beego what template to render for the page, in this case
"index.tpl". If you don't set the template it will default to
"controller/method\_name.tpl" where method\_name is the method that was
called on the controller. In this example it would be
"maincontroller/get.tpl"
