To not populate +certain fields, use a dash for the name and it will be ignored: + + type Person struct { + Name string `schema:"name"` // custom name + Phone string `schema:"phone"` // custom name + Admin bool `schema:"-"` // this field is never set + } + +The supported field types in the destination struct are: + + * bool + * float variants (float32, float64) + * int variants (int, int8, int16, int32, int64) + * string + * uint variants (uint, uint8, uint16, uint32, uint64) + * struct + * a pointer to one of the above types + * a slice or a pointer to a slice of one of the above types + +Non-supported types are simply ignored, however custom types can be registered +to be converted. + +To fill nested structs, keys must use a dotted notation as the "path" for the +field. So for example, to fill the struct Person below: + + type Phone struct { + Label string + Number string + } + + type Person struct { + Name string + Phone Phone + } + +...the source map must have the keys "Name", "Phone.Label" and "Phone.Number". +This means that an HTML form to fill a Person struct must look like this: + + <form> + <input type="text" name="Name"> + <input type="text" name="Phone.Label"> + <input type="text" name="Phone.Number"> + </form> + +Single values are filled using the first value for a key from the source map. +Slices are filled using all values for a key from the source map. So to fill +a Person with multiple Phone values, like: + + type Person struct { + Name string + Phones []Phone + } + +...an HTML form that accepts three Phone values would look like this: + + <form> + <input type="text" name="Name"> + <input type="text" name="Phones.0.Label"> + <input type="text" name="Phones.0.Number"> + <input type="text" name="Phones.1.Label"> + <input type="text" name="Phones.1.Number"> + <input type="text" name="Phones.2.Label"> + <input type="text" name="Phones.2.Number"> + </form> + +Notice that only for slices of structs the slice index is required. +This is needed for disambiguation: if the nested struct also had a slice +field, we could not translate multiple values to it if we did not use an +index for the parent struct. + +There's also the possibility to create a custom type that implements the +TextUnmarshaler interface, and in this case there's no need to register +a converter, like: + + type Person struct { + Emails []Email + } + + type Email struct { + *mail.Address + } + + func (e *Email) UnmarshalText(text []byte) (err error) { + e.Address, err = mail.ParseAddress(string(text)) + return + } + +...an HTML form that accepts three Email values would look like this: + + <form> + <input type="email" name="Emails.0"> + <input type="email" name="Emails.1"> + <input type="email" name="Emails.2"> + </form> +*/ +package schema diff --git a/vendor/github.com/gorilla/schema/encoder.go b/vendor/github.com/gorilla/schema/encoder.go new file mode 100644 index 000000000..bf1d511e6 --- /dev/null +++ b/vendor/github.com/gorilla/schema/encoder.go @@ -0,0 +1,195 @@ +package schema + +import ( + "errors" + "fmt" + "reflect" + "strconv" +) + +type encoderFunc func(reflect.Value) string + +// Encoder encodes values from a struct into url.Values. +type Encoder struct { + cache *cache + regenc map[reflect.Type]encoderFunc +} + +// NewEncoder returns a new Encoder with defaults. +func NewEncoder() *Encoder { + return &Encoder{cache: newCache(), regenc: make(map[reflect.Type]encoderFunc)} +} + +// Encode encodes a struct into map[string][]string. +// +// Intended for use with url.Values. +func (e *Encoder) Encode(src interface{}, dst map[string][]string) error { + v := reflect.ValueOf(src) + + return e.encode(v, dst) +} + +// RegisterEncoder registers a converter for encoding a custom type. +func (e *Encoder) RegisterEncoder(value interface{}, encoder func(reflect.Value) string) { + e.regenc[reflect.TypeOf(value)] = encoder +} + +// SetAliasTag changes the tag used to locate custom field aliases. +// The default tag is "schema". +func (e *Encoder) SetAliasTag(tag string) { + e.cache.tag = tag +} + +// isValidStructPointer test if input value is a valid struct pointer. +func isValidStructPointer(v reflect.Value) bool { + return v.Type().Kind() == reflect.Ptr && v.Elem().IsValid() && v.Elem().Type().Kind() == reflect.Struct +} + +func isZero(v reflect.Value) bool { + switch v.Kind() { + case reflect.Func: + case reflect.Map, reflect.Slice: + return v.IsNil() || v.Len() == 0 + case reflect.Array: + z := true + for i := 0;
