Looking for CRUD implementation example.

[mm]

Could someone point me to a nice implementation of how CRUD is used in GO? So far I have found this -

http://paste.ubuntu.com/8503695/

but it is incomplete. I come from Python, so I really need an example of how CRUD is used in GO.

thanks

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.

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.*")

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

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.
