QUESTION
I am trying to validate the request body according to this struct using validator. But in Postman it always throws an error when validating the struct. I just want all values to be required when making a request.

I see a problem in your code the link you have shared is https://github.com/go-playground/validator
but in the code, import is gopkg.in/validator.v2
If you are using the go-playground validator
Use below code to validate
QUESTION
I am using go-playground/validator/v10
to validate some input and have some trouble with custom validation tags and functions. The problem is that the function is not called when one of the struct fields is a different struct. This is an example:
ANSWER
Answered 2021-Apr-26 at 23:38The function validator.RegisterValidation(...)
is registering a field level custom validator, as the type of the registered function suggests func(fl validator.FieldLevel) bool
.
Struct fields themselves are not validated this way and your custom validator is ignored.
To validate a struct field you should use validate.RegisterStructValidation(myValidate, ChildStruct{})
, where the function myValidate
is of type validator.StructLevelFunc
.
Inside this function you can then perform validation of the struct, either the field itself and/or its nested fields:

QUESTION
I am using the below code to sync goroutines. Recently while investigating a bug I found that the below code is not working always. Approx one out of five times it fails. The channel quit
gets the message before my out
channel. I am able to consistently reproduce this issue in my local (not in go-playground) and in k8s environments. As a workaround, I am now using sync.Map
to synchronize.
Is there a way to fix the below code?
...ANSWER
Answered 2021-Apr-11 at 05:33The out channel can contain values when quit is received. Fix by making out an unbuffered channel:

I'm trying to catch binding errors with gin gonic and it's working fine for all validation errors from go-playground/validator/v10 but i'm having an issue catching errors when unmarshalling into the proper data type.

QUESTION
I have a struct that i'm trying to validate a struct using validator v10 for which field can be of type null.XX from null.v4 package.
...ANSWER
Answered 2020-Oct-14 at 11:13You dont need to unparse the field inside the validator and make a custom case just for the special type.
Instead just create a new type then you can just use the normal bindings.
QUESTION
I recently found out that Go compiles down to WebAssembly. Cool!
As per this Go doc, the Go toolchain itself is written in Go.
This made me think, can the Go compiler run in the browser? Can I make a website which given a file path through an upload button (though, without uploading anything), can compile a Go project and return the executable as a "download"?
The end result I'm looking for is an executable file saved to disk, not for the Go code to run in a browser, but I don't need the exact scenario above to be followed as long as that is the final result.
If this is possible, what are the limitations, if any?
Additional resources I have looked at:
- A compiler from Go to WASM on GitHub
- Someone working on a game where entered Go code runs in the browser
EDIT: I have started work on this, based on a similar project. The repo can be found here: https://github.com/TR-SLimey/IBGC
...ANSWER
Answered 2020-Jul-03 at 18:00It is possible, but it's hard to do.
You can't access files using WebAssembly. Instead, you need the user to drop a folder inside the webpage and use the File and Directory Entries API to get the files and their contents.
But the real problem is passing the files from JS to WASM and vice-versa. You'll also need to replace in the compiler source code all the calls to the Go standard library that would access files to calls to JS functions. Those function need to access the WASM memory directly. You will need to modify the compiler quite a bit.
To download the binary, you can create a Blob
, use URL.createObjectURL()
to get an URL to that blob, create an element with
.download = true
and .href =
, and then .click()
it.
The performance might be worse than running the Go compiler directly, but other than that it should work just fine.
