dancannon / gorethink_tododemo Goto Github PK

Is this repository deprecated?
E.g. I see this repo is using gorethink struct tags, however "Old-style gorethink struct tags are supported but deprecated."

I'd like to filter with the following code. However I recieve an invalid memory error. I'm curious if you could point me in the right direction. I'm somewhat new to both go and rethink, please excuse my ignorance.
I'd like to search the "name" field for a keyword substring. There's an Expr line in the docs but I'm lost as to what the Field,Nth,Field chaining does. Could you clarify this for me?

Thanks in advance

func (im *ImageService) SearchByKeyword(keyword string) []interface{} {
    var err error
    rows, err := r.Table("images").Filter(func(row r.RqlTerm) r.RqlTerm {
        //Expr("id:0,name:mlucy,foo:bar").Match("name:(\\w+)").Field("groups").Nth(0).Field("str")
        s := []string{"^", keyword}
        fmt.Printf(strings.Join(s, " "))
        return r.Expr(row.Field("name")).Match(s)
    }).Run(session)

    if err != nil {
        fmt.Println(err)
    }

    fmt.Println(rows)

this seems to be not using web sockets yet ?
if i open two tabs, they do not keep up to date.

the code is really well structured. Probably the best example i have seen.
i would be happy to finish it, but need a little more advice.

when using the latest GoRethink driver the app runs into io-timeout every time the Timeout limit (set in server.go) is reached.
with v0.6.3 everything works like expected.

When firing up the demo, there's an error on the main page:

template: index.gohtml:19:28: executing "index.gohtml" at <.Items>: can't evaluate field Items in type []main.TodoItem

Further, attempting to submit an entry works (it is inserted into the DB) however there are http: multiple response.WriteHeader calls being made.
