Dynamic drop down list

ruby-talk
1

Hello,

I'm trying to make a drop down list from an array. For now, just hard
coding, later will use an actual array. This is in an erb file.

The first problem is that I can't find documentation on "select". Is it
a function, a class? (I'm new to Ruby). Can you point me to the
documentation?

The second problem is that according to some forums, the following
should work, but it doesn't, and I can't figure out the error message.

<%= select("borrowers", "borrower_id", [ ["name1", "value1"],["name2",
"value2"],["name3", "value3"]]) %>

ERROR: wrong argument type String (expected Array)

I have tried everything. Thanks!

You can do how follow:

<% menus_list = [["name1", "value1"], ["name2", "value2"], ["name3",
"value3"]] %>
<%= select("borrowers", "borrower_id", options_for_select(menus_list)) %>

Hugs.
