How to use GroupBy?

[vizcay]

Hi, sorry but I wasn't able to locate the docs for that (tried at https://godoc.org/github.com/gobuffalo/buffalo and also at the README but no examples).

I need to pair a slice into 2 per row pairs.

Ruby developer, learning Go and Buffalo at the same time..

Thanks!

Sounds like a good case for a custom helper ( https://gobuffalo.io/en/docs/custom-helpers ). If you give more info/an example of use, one of us may be able to help more with how you might make that helper.

That helper take a int (how many groups you want) and a slice to divide up.

The tests explain it a bit clearer; but we need more docs there.

<%= form_for(contact, {action: "/contact"}) { %> <%= f.InputTag("Name") %> <%= f.InputTag("Email") %> <%= f.InputTag("Company") %> <%= f.TextArea("Description", {rows: 10, label: "Please let us what you are looking for in regards to training."}) %> Please check the topics that are of interest for you.

That’s a real world example. It takes the slice and breaks it into 2 so I can make two nice columns in HTML On Dec 13, 2018, 3:29 AM -0500, Matthew Clark [email protected], wrote:

Closing. It seems like it's an answered question.
