Controllers

Most of the time, you do not need to declare controllers in Hexya. Instead, declare an "Action" with the views you want and a menu to access it. The framework will take care of the UI including rendering views, navigation, CRUD, etc.

Iterative Definition and Modularity

Each part of the Hexya Framework is modular and follow the Iterative Definition concept.

This means that an object (for example a model class) can be defined in a module and then extended in place by dependent modules. So any subsequent modification will be made on the original model and will be available for the whole application.

This makes it possible to customize the application by creating a new module with the new features without forking and still benefiting from upstream updates.

Example on models:

package Avar fields_User = map[string]models.FieldDefinition{ "Name": fields.Char{String: "Name", Help: "The user's username", Unique: true, NoCopy: true, OnChange: h.User().Methods().OnChangeName()}, "Email": fields.Char{Help: "The user's email address", Size: 100, Index: true}, "Password": fields.Char{}, "IsStaff": fields.Boolean{String: "Is a Staff Member", Help: "Set to true if this user is a member of staff"},}func init() { models.NewModel("User") h.User().AddFields(fields_User)}

package Bvar fields_User = map[string]models.FieldDefinition{ "Size": models.Float{},}func init() { h.User().AddFields(fields_User)}

// Anywhere elsenewUser := h.User().Create(env, h.User().NewData(). SetName("John"). SetEmail("john@example.com"). SetSize(185.7))fmt.Println(newUser.Name())// output : Johnfmt.Println(newUser.Size())// output : 185.7

Model methods can be extended too:

package A// GetEmail returns the Email of the user with the given namefunc user_GetEmail(rs m.UserSet, name string) string { user := h.User().Search(rs.Env(), q.User().Name().Equals(name)).Limit(1) user.Sanitize() return user.Email() }func init() { h.User().NewMethod("GetEmail", user_GetEmail)}

package Bfunc init() { h.User().Methods().GetEmail().Extend( func(rs m.UserSet, name string) string { res := rs.Super().GetEmail(name) return fmt.Sprintf("<%s>", res) })}

// Anywhere elseemail := h.User().NewSet(env).GetEmail("John")fmt.Println(email)// output:

And it works also with views:

And the rendered view will be :
