Rails Text Field Helper Returns Array?

I have a rails form helper that looks like this:

<%= text_field :username,nil, {:placeholder=>"new username", :value=>nil} %>

When I look at the HTML generated by this, it looks like:

input id="username_" name="username[]" placeholder="new username" size="30" type="text"

(HTML <> removed)

This makes accessing the username attribute troubling. I do: 

@user.username = [:username]

Params looks like

{"utf8"=>"✓", "authenticity_token"=>"...", "username"=>["newusername"], "commit"=>"Save", "id"=>"10"}

And @user.username gets set to (escaped) ["newusername"] - it gets set to "--- - newusername"

Can't figure out how to get rid of the [] around the form value! What should I do?

EDIT: Entire form as generated by rails: http://tny.cz/0d5a9397

you should use text_field_tag

<%= text_field_tag :username, nil, :placeholder => "new username" %>

using text_field somehow expects you to work on a resource.

text_field :user, :username

You can still use text_field but you have to explicitly set the name

text_field :username, nil, name: 'username'

What I didn't know was if you pass nil as the second argument, it will set that field as a collective tag so I learned something new today.
