add resource for routes

[keweegen]

Examples

Create handlers

func bookHandlers() rest.ResourceHandlers {
	return rest.ResourceHandlers{
		"Index": controllers.FindBooks,
		"Create": controllers.CreateBook,
		"Show": controllers.FindBook,
		"Update": controllers.UpdateBook,
		"Delete": controllers.DeleteBook,
	}
}

Initialize resource routes

func SetupRouter(r *gin.Engine) *gin.Engine {
	rest.Resource(r.Group("books"), bookHandlers(), rest.ResourceOptions{})
	rest.Resource(
		e.Group("/api/v1/tests"),
		bookHandlers(),
		rest.ResourceOptions{
			Param:   "customParam",
			Exclude: []string{"Create", "Update", "Delete"},
		},
	)
	return r
}

Run

go run .

output:
[GIN-debug] PUT    /books/:book              --> go-api/controllers.UpdateBook (3 handlers)
[GIN-debug] DELETE /books/:book              --> go-api/controllers.DeleteBook (3 handlers)

Personally, I'd go with having enum-style indexes, rather than strings, to avoid possibility of having a typo:

const (
	MethodIndex = iota
	MethodCreate
	MethodShow
	MethodUpdate
	MethodDelete
)

But I agree your way the code looks more readable.

Good addition, just a small concern regarding query param handling.

I'm not sure why you did this magic on routeMethod.Param. I guess you probably were thinking about the safety and bad names specified by users? I would remove this and keep this up to the users to think about what is allowed and what is not in the query string.
Also, this adds two unnecessary dependencies on 3rd-party packages:
