Creating models

Models are normally the best way to handle the numerous databases used in web applications. The bee new project does not contain an example of models. Demos on implementing and using models can instead be found in bee api projects.

The Controller can automatically handle models for simple applications.

Larger applications with more reusable code requiring logic separation must use models. Reusable logic can be factored out into a Model and used to handle database interactions. The following is an example:

package models
import (
    "loggo/utils"
    "path/filepath"
    "strconv"
    "strings"
)
var (
    NotPV []string = []string{"css", "js", "class", "gif", "jpg", "jpeg", "png", "bmp", "ico", "rss", "xml", "swf"}
)
const big = 0xFFFFFF
func LogPV(urls string) bool {
    ext := filepath.Ext(urls)
    if ext == "" {
        return true
    }
    for _, v := range NotPV {
        if v == strings.ToLower(ext) {
            return false
        }
    }
    return true
}

Please see MVC Models for the specific examples of database models and Beego’s ORM framework. The next section will cover writing views.
