[go-nuts] Looking for CRUD implementation example.

This is a strange question.

You're looking for an example that demonstrates how to do Create, Update,
Delete with a relational database in Go? You can start
here: http://golang.org/pkg/database/sql/
Or are you looking for an ORM?

Sorry for being so oblique. Im using mgo/mongodb
I am trying to understand, specifically how to do GET and POST... usually
in python I have something like this:

class Edit(BaseHandler, Jinja2Rendering): @auth_admin def get(self, user_id): """Display a user profile """

Not sure how to do that in my func(c *context) UserEdit(rw web.ResponseWriter, req *web.Request) {}


On my list page I have the list of users and when you click on one you get to the user edit page.

I get from my list page to my edit page like so


rootRouter.Get("/user/edit/*:user_id*", (*Context).UserEdit)

In python I get the user_id from params. How does that work in go?

Read http://golang.org/doc/articles/wiki/ it has an example how to use FormValue.
Then http://astaxie.gitbooks.io/build-web-application-with-golang/content/ for a thorough explanation how to build web apps with Go.

Thanks so much Egon, those are great links for me!!

Ok found what I am looking for...Using Gocraft:

You can capture path variables like this:

router.Get("/suggestions/:suggestion_id/comments/:comment_id")

In your handler, you can access them like this:

func (c *YourContext) Root(rw web.ResponseWriter, req *web.Request) {
     fmt.Fprint(rw, "Suggestion ID:", req.PathParams["suggestion_id"])
     fmt.Fprint(rw, "Comment ID:", req.PathParams["comment_id"])
}

You can also validate the format of your path params with a regexp. For
instance, to ensure the 'ids' start with a digit:

router.Get("/suggestions/:suggestion_id:\\d.*/comments/:comment_id:\\d.*")

You're probably looking how to do an app using a framework (router at
least) and a database backend. I read you use MongoDB in Python, so for
that you should use the excellent Mongo library by Gustavo Niemeyer:

http://labix.org/mgo

As for frameworks, depending on the level of the app you want to code there
are a LOT, if you are only looking for a router and stuff to use with Go's
standard lib... I can definitely recommend Gorilla Toolkit
(http://www.gorillatoolkit.org/) you want to be using the MUX package at
least, it supports everything from subdomains to regular expression routing.

As for frameworks, Martini, Gin, and Goji are the simplest to get into IMHO.

https://github.com/go-martini/martini
https://github.com/gin-gonic/gin
https://goji.io/

Most of them have great documentation to get you started, as for
tutorialesque writing in this matter a simple Google search yields some of
them (once you know what to look for).

Hope this helps.

Thank you so much Guillermo, yes I need to keep it light so am just using
mgo and gocraft. I am really liking Go so far. Its a little complex for me
but once it compiles I know I have something sure and lightning fast.

Also forgot... two must videos to watch:
