Question

Couldn’t seem to find the answer to this question – what is the haml syntax for adding styles or a class styling to elements within a rails form_for?

The code I am dealing with is

.row.form
.threecol
.sevencol
    = form_for @article do |a|
      %h3= a.label "title"
      =    a.text_field :title 
      %h3= a.label "description"
      =    a.text_area :description
      %h3= a.label "body"
      =    a.text_area :body
      %br/
      =  a.submit "Post Article"
 .twocol.last

I am wanting to add a style to the text area description element.
I have tried (where new_desc is the class styling)

= a.text_area.new_desc :description

and

= a.text_area { :style ... } :description

but both failed to compile.
Can anyone help with this (hopefully trivial) problem?

Answer 1

text_area is a method that takes (object, method, and options) (http://api.rubyonrails.org/classes/ActionView/Helpers/FormHelper.html#method-i-text_area)

When you have it attached to a form object, you withhold the object, so it becomes text_area(method, options={})

= a.text_area :description, class: "description"

or

= a.text_area :description, class: "description", style: "font-size: 45"
