Use the command line tools - adm to help you quickly generate configuration files:
install adm
go install github.com/GoAdminGroup/adm
generate
Execute the command in your project folder
adm generate
Notice: use space to choose table, not enter
Fill in the information according to the prompts. After the run, a file users.go will be generated. This is the configuration file corresponding to the data table. How to configure it is described in detail later.
Step 2. Set access url
After the configuration file is generated, a routing configuration file tables.go will also be generated :
package main
import "github.com/GoAdminGroup/go-admin/plugins/admin/models"
// The key of Generators is the prefix of table info url.
// The corresponding value is the Form and Table data.
//
// http://{{config.DOMAIN}}:{{PORT}}/{{config.PREFIX}}/info/{{key}}
//
// example:
//
// "user" => http://localhost:9033/admin/info/user
//
var Generators = map[string]models.TableGenerator{
"user": GetUserTable,
}
"user" is the corresponding access route prefix, GetUserTable is the table data generation method. The corresponding access routing address is: http://localhost:9033/admin/info/user
Step 3. Initialize and load in the engine
To initialize, you need to call the eng.AddGenerators method, and then pass the Generators above.
package main
import (
_ "github.com/GoAdminGroup/go-admin/adapter/gin" // Import the adapter, it must be imported. If it is not imported, you need to define it yourself.
_ "github.com/GoAdminGroup/themes/adminlte" // Import the theme
_ "github.com/GoAdminGroup/go-admin/modules/db/drivers/mysql" // Import the sql driver
"github.com/gin-gonic/gin"
"github.com/GoAdminGroup/go-admin/engine"
"github.com/GoAdminGroup/go-admin/plugins/admin"
"github.com/GoAdminGroup/go-admin/modules/config"
"github.com/GoAdminGroup/go-admin/modules/language"
)
func main() {
r := gin.Default()
eng := engine.Default()
cfg := config.Config{
Databases: config.DatabaseList{
"default": {
Host: "127.0.0.1",
Port: "3306",
User: "root",
Pwd: "root",
Name: "godmin",
MaxIdleCon: 50,
MaxOpenCon: 150,
Driver: config.DriverMysql,
},
},
UrlPrefix: "admin",
Store: config.Store{
Path: "./uploads",
Prefix: "uploads",
},
Language: language.CN,
}
// AddGenerator can also be used to load the Generator, like:
// eng.AddGenerator("user", GetUserTable)
eng.AddConfig(cfg).
AddGenerators(Generators). // 加载插件
Use(r)
r.Run(":9033")
}
Step 4. Set access menu
After running, access the login URL, enter the menu management page, and then set the management menu of the data table to enter in the sidebar.

Initialized by calling models.NewDefaultTable(models.DefaultTableConfig) method to pass data table model configuration. The data table model is configured as:
type Config struct {
Driver string // database driver
Connection string // database connection name, defined in the global configuration
CanAdd bool // Can I add data
Editable bool // Can I edit
Deletable bool // Can I delete it
Exportable bool // Whether it can be exported
PrimaryKey PrimaryKey // primary key of the data table
}
type PrimaryKey struct {
Type db.DatabaseType // primary key type
Name string // primary key name
}
The business data table generation method is a function that returns a type object of models.Table. The following is the definition of models.Table:
It mainly includes GetInfo() and GetForm(). The UI corresponding to the type returned by these two functions is the table for displaying data and the form for editing or creating data. The screenshots are as follows:
This is the Info.
This is the Form.

Filter function FilterFn and processing function PostFn description
The data which framework retrieve from database will be displayed in the table or form. If you want to transform them before displaying, for example turn capital or add some html style etc, you can do that using the field filter callback function. Of course, the framework have some built-in data process functions which will be introduced in the chapter of admin table.
// FieldModel contains ID and value of the single query result.
type FieldModel struct {
ID string
Value string
}
// FieldFilterFn determines the value that is retrieved from the database
// and passes to the format displayed by the front end.
//
// The type currently accepted for return is: template.HTML, string, []string
//
// For tables, you can return the template.HTML type, including html and css
// styles, so that the fields in the table can be personalized, such as:
//
// FilterFn: func(model types.FieldModel) interface{} {
// return template.Get("adminlte").Label().SetContent(template2.HTML(model.Value)).GetContent()
// },
//
// For forms, note that if it is a select box type: Select/SelectSingle/SelectBox,
// you need to return an array: []string, such as:
//
// FilterFn: func(model types.FieldModel) interface{} {
// return strings.Split(model.Value, ",")
// },
//
// For other form types, return the string type
//
type FieldFilterFn func(value FieldModel) interface{}
// PostFieldModel contains ID and value of the single query result.
type PostFieldModel struct {
ID string
Value FieldModelValue
Row map[string]interface{}
}
type FieldModelValue []string
func (r FieldModelValue) Value() string {
return r.First()
}
func (r FieldModelValue) First() string {
return r[0]
}
