}

func (NumberOptions) Validate 

func (o NumberOptions) Validate() error

type RelationOptions 

type RelationOptions struct {
	MaxSelect     int    `form:"maxSelect" json:"maxSelect"`
	CollectionId  string `form:"collectionId" json:"collectionId"`
	CascadeDelete bool   `form:"cascadeDelete" json:"cascadeDelete"`
}

func (RelationOptions) Validate 

func (o RelationOptions) Validate() error

type Schema 

type Schema struct {
	// contains filtered or unexported fields
}

Schema defines a dynamic db schema as a slice of `SchemaField`s.

func NewSchema 

func NewSchema(fields ...*SchemaField) Schema

NewSchema creates a new Schema instance with the provided fields.

func (*Schema) AddField 

func (s *Schema) AddField(newField *SchemaField)

AddField registers the provided newField to the current schema.

If field with `newField.Id` already exist, the existing field is replaced with the new one.

Otherwise the new field is appended to the other schema fields.

func (*Schema) AsMap 

func (s *Schema) AsMap() map[string]*SchemaField

AsMap returns a map with all registered schema field. The returned map is indexed with each field name.

func (*Schema) Clone 

func (s *Schema) Clone() (*Schema, error)

Clone creates a deep clone of the current schema.

func (*Schema) Fields 

func (s *Schema) Fields() []*SchemaField

Fields returns the registered schema fields.

func (*Schema) GetFieldById 

func (s *Schema) GetFieldById(id string) *SchemaField

GetFieldById returns a single field by its id.

func (*Schema) GetFieldByName 

func (s *Schema) GetFieldByName(name string) *SchemaField

GetFieldByName returns a single field by its name.

func (*Schema) InitFieldsOptions 

func (s *Schema) InitFieldsOptions() error

InitFieldsOptions calls `InitOptions()` for all schema fields.

func (Schema) MarshalJSON 

func (s Schema) MarshalJSON() ([]byte, error)

MarshalJSON implements the json.Marshaler interface.

func (*Schema) RemoveField 

func (s *Schema) RemoveField(id string)

RemoveField removes a single schema field by its id.

This method does nothing if field with `id` doesn't exist.

func (*Schema) Scan 

func (s *Schema) Scan(value any) error

Scan implements [sql.Scanner] interface to scan the provided value into the current Schema instance.

func (*Schema) UnmarshalJSON 

func (s *Schema) UnmarshalJSON(data []byte) error

UnmarshalJSON implements the json.Unmarshaler interface.

On success, all schema field options are auto initialized.

func (Schema) Validate 

func (s Schema) Validate() error

Validate makes Schema validatable by implementing validation.Validatable interface.

Internally calls each individual field's validator and additionally checks for invalid renamed fields and field name duplications.

func (Schema) Value 

func (s Schema) Value() (driver.Value, error)

Value implements the driver.Valuer interface.

type SchemaField 

type SchemaField struct {
	System   bool   `form:"system" json:"system"`
	Id       string `form:"id" json:"id"`
	Name     string `form:"name" json:"name"`
	Type     string `form:"type" json:"type"`
	Required bool   `form:"required" json:"required"`
	Unique   bool   `form:"unique" json:"unique"`
	Options  any    `form:"options" json:"options"`
}

SchemaField defines a single schema field structure.

func (*SchemaField) ColDefinition 

func (f *SchemaField) ColDefinition() string

ColDefinition returns the field db column type definition as string.

func (*SchemaField) InitOptions 

func (f *SchemaField) InitOptions() error

InitOptions initializes the current field options based on its type.

Returns error on unknown field type.

func (SchemaField) MarshalJSON 

func (f SchemaField) MarshalJSON() ([]byte, error)

MarshalJSON implements the json.Marshaler interface.

func (*SchemaField) PrepareValue 

func (f *SchemaField) PrepareValue(value any) any

PrepareValue returns normalized and properly formatted field value.

func (SchemaField) String 

func (f SchemaField) String() string

String serializes and returns the current field as string.

func (*SchemaField) UnmarshalJSON 

func (f *SchemaField) UnmarshalJSON(data []byte) error

UnmarshalJSON implements the json.Unmarshaler interface.

The schema field options are auto initialized on success.

func (SchemaField) Validate 

func (f SchemaField) Validate() error

Validate makes `SchemaField` validatable by implementing validation.Validatable interface.

type SelectOptions

	Pattern string `form:"pattern" json:"pattern"`
}

func (TextOptions) Validate 

func (o TextOptions) Validate() error
