Description
Example:
type Form struct {
Field []string `form:"field"`
}
form := Form{ Field: []string{"value1", "value2"} }
// vals is contains 'field': "value3", "value4"
_ := Decoder.Decode(&form, vals)
// form.Field contains now "value1", "value2", "value3", "value4".
// Excepted was only "value3", "value4"If I decode the HTTP post values to this struct, the Field property gets appended by the values in the post data instead of replaced.
The use case is the following:
I pre-fill the Form struct with data based on the DB entity. I use this struct also in the view template to render the values.
If I would fill the Form struct after the decoding, it will override all the decoded fields if I not check every single field.
My logical expectation of the form decoder is:
- If the form field exists in the values, make sure the value match the decoded value (now it's appending string array, don't tested other kind of arrays/struct array)
- If not just leave the field how it is (works)
