We currently support binding of JSON, XML and standard form values (foo=bar&boo=baz). +Gin uses [**go-playground/validator.v8**](https://github.com/go-playground/validator) for validation. Check the full docs on tags usage [here](http://godoc.org/gopkg.in/go-playground/validator.v8#hdr-Baked_In_Validators_and_Tags). + Note that you need to set the corresponding binding tag on all fields you want to bind. For example, when binding from JSON, set `json:"fieldname"`. -When using the Bind-method, Gin tries to infer the binder depending on the Content-Type header. If you are sure what you are binding, you can use BindWith. +Also, Gin provides two sets of methods for binding: +- **Type** - Must bind + - **Methods** - `Bind`, `BindJSON`, `BindQuery` + - **Behavior** - These methods use `MustBindWith` under the hood. If there is a binding error, the request is aborted with `c.AbortWithError(400, err).SetType(ErrorTypeBind)`. This sets the response status code to 400 and the `Content-Type` header is set to `text/plain; charset=utf-8`. Note that if you try to set the response code after this, it will result in a warning `[GIN-debug] [WARNING] Headers were already written. Wanted to override status code 400 with 422`. If you wish to have greater control over the behavior, consider using the `ShouldBind` equivalent method. +- **Type** - Should bind + - **Methods** - `ShouldBind`, `ShouldBindJSON`, `ShouldBindQuery` + - **Behavior** - These methods use `ShouldBindWith` under the hood. If there is a binding error, the error is returned and it is the developer's responsibility to handle the request and error appropriately. -You can also specify that specific fields are required. If a field is decorated with `binding:"required"` and has a empty value when binding, the current request will fail with an error. +When using the Bind-method, Gin tries to infer the binder depending on the Content-Type header.

Because of this, straightforward rules for *scannability* had to be developed. Iff something is "Scannable", then it is used directly in `rows.Scan`; if it's not, then the standard sqlx struct rules apply. - -Something is scannable if any of the following are true: - -* It is not a struct, ie. `reflect.ValueOf(v).Kind() != reflect.Struct` -* It implements the `sql.Scanner` interface -* It has no exported fields (eg. `time.Time`) - -## embedded structs - -Scan targets obey Go attribute rules directly, including nested embedded structs. Older versions of sqlx would attempt to also descend into non-embedded structs, but this is no longer supported. - -Go makes *accessing* '[ambiguous selectors](http://play.golang.org/p/MGRxdjLaUc)' a compile time error, defining structs with ambiguous selectors is legal. Sqlx will decide which field to use on a struct based on a breadth first search of the struct and any structs it embeds, as specified by the order of the fields as accessible by `reflect`, which generally means in source-order. This means that sqlx chooses the outer-most, top-most matching name for targets, even when the selector might technically be ambiguous. - -## scan safety - -By default, scanning into structs requires the structs to have fields for all of the -columns in the query. This was done for a few reasons: - -* A mistake in naming during development could lead you to believe that data is - being written to a field when actually it can't be found and it is being dropped -* This behavior mirrors the behavior of the Go compiler with respect to unused - variables -* Selecting more data than you need is wasteful (more data on the wire, more time - marshalling, etc) - -Unlike Marshallers in the stdlib, the programmer scanning an sql result into a struct -will generally have a full understanding of what the underlying data model is *and* -full control over the SQL statement. - -Despite this, there are use cases where it's convenient to be able to ignore unknown -columns. In most of these cases, you might be better off with `ScanSlice`, but where -you want to still use structs, there is now the `Unsafe` method. Its usage is most -simply shown in an example: - -```go - db, err := sqlx.Connect("postgres", "user=foo dbname=bar sslmode=disable") - if err != nil { - log.Fatal(err) - } - - type Person { - Name string - } - var p Person - - // This fails, because there is no destination for location in Person - err = db.Get(&p, "SELECT name, location FROM person LIMIT 1") - - udb := db.Unsafe() - - // This succeeds and just sets `Name` in the p struct - err = udb.Get(&p, "SELECT name, location FROM person LIMIT 1") -``` - -The `Unsafe` method is implemented on `Tx`, `DB`, and `Stmt`. When you use an unsafe -`Tx` or `DB` to create a new `Tx` or `Stmt`, those inherit its lack of safety. - diff --git a/vendor/github.com/jmoiron/sqlx/bind.go b/vendor/github.com/jmoiron/sqlx/bind.go index 2f1ec2b..0fdc443 100644 --- a/vendor/github.com/jmoiron/sqlx/bind.go +++ b/vendor/github.com/jmoiron/sqlx/bind.go @@ -2,7 +2,12 @@ package sqlx import ( "bytes" + "errors" + "reflect" "strconv" + "strings" + + "github.com/jmoiron/sqlx/reflectx" ) // Bindvar types supported by Rebind, BindMap and BindStruct. @@ -16,13 +21,13 @@ const ( // BindType returns the bindtype for a given database given a drivername. func BindType(driverName string) int { switch driverName { - case "postgres", "pgx": + case "postgres", "pgx", "pq-timeouts", "cloudsqlpostgres": return DOLLAR case "mysql": return QUESTION case "sqlite3": return QUESTION - case "oci8": + case "oci8", "ora", "goracle": return NAMED } return UNKNOWN @@ -31,37 +36,41 @@ func BindType(driverName string) int { // FIXME: this should be able to be tolerant of escaped ?'s in queries without // losing much speed, and should be to avoid confusion. -// FIXME: this is now produces the wrong results for oracle's NAMED bindtype - // Rebind a query from the default bindtype (QUESTION) to the target bindtype. func Rebind(bindType int, query string) string { - if bindType != DOLLAR { + switch bindType { + case QUESTION, UNKNOWN: return query } - qb := []byte(query) // Add space enough for 10 params before we have to allocate - rqb := make([]byte, 0, len(qb)+10) - j := 1 - for _, b := range qb { - if b == '?' { + rqb := make([]byte, 0, len(query)+10) + + var i, j int + + for i = strings.Index(query, "?"); i != -1; i = strings.Index(query, "?") { + rqb = append(rqb, query[:i]...) + + switch bindType { + case DOLLAR: rqb = append(rqb, '$') - for _, b := range strconv.Itoa(j) { - rqb = append(rqb, byte(b)) - } - j++ - } else { - rqb = append(rqb, b) + case NAMED: + rqb = append(rqb, ':', 'a', 'r', 'g') } + + j++ + rqb = strconv.AppendInt(rqb, int64(j), 10) + + query = query[i+1:] } - return string(rqb) + + return string(append(rqb, query...)) } // Experimental implementation of Rebind which uses a bytes.Buffer.
