google app engine - Execute formatted time in a slice with html/template -

i'm making simple webserver can host blog, whatever do; can not execute proper formatted time html/template.

here's do:

i've created struct:

type blogpost struct {     title   string     content string     date    time.time } 

next i've created little func retrieves blogposts corresponding title/dates appengine datastore , return slice:

func getblogs(r *http.request, max int) []blogpost {     c := appengine.newcontext(r)     q := datastore.newquery("blogpost").order("-date").limit(max)     bp := make([]blogpost, 0, max)     q.getall(c, &bp)     return bp } 

finally, in bloghandler create slice based on retrieved data appengine datastore using:

blogs := getblogs(r, 10) 

now when execute template called blog this, dates of blogs being parsed default dates:

blog.execute(w, blogs) // gives dates like: 2013-09-03 16:06:48 +0000 utc 

so, me, being golang n00b am, function following give me result want

blogs[0].date = blogs[0].date.format("02-01-2006 15:04:05") // return 03-09-2013 16:06:48, @ least when print formatted date is. 

however results in type conflict ofcourse, tried solve using:

blogs[0].date, _ = time.parse("02-01-2006 15:04:05", blogs[0].date.format("02-01-2006 15:04:05")) // returns once again: 2013-09-03 16:06:48 +0000 utc 

it n00b thing oversaw once again, can't see how can't override time.time type in slice or @ least print in format want.

your date field has type time.time. if format string, , parse back, you'll once again time.time value, still print default way when template execution calls string method, it's not solving problem.

the way solve providing template formatted time string instead of time value, , can in multiple ways. example:

• add method blog post type named formatteddate or similar, returns string formatted in style of preference. that's easiest, , nicest way if don't have fancy use case.

• add string field blog type named formatteddate or similar; that's similar above option, have careful set , update field whenever necessary, i'd prefer method option instead.

• if you'd format time values in multiple ways within template, might opt define template formatter function, might {{post.date | fdate "02-01-2006 15:04:05"}}. see documentation on template.funcs, funcmap type, , this example details on how that.
