Pass variable to action

Rails
#1

Hi,

Still learning rails and have a basic question. Can I pass any variable
thru the params hash to an action?

eg “in_progress”

View:
<%= f.submit “Add image/video”, :in_progress=> “true” %>

Controller:
def update
@question = Question.find(params[:id])

if params[:in_progress] == "true"
  @question.attributes = params[:question]
  if @question.save(:validate => false)
    redirect_to gallery_path(session[:minisection_id]), id:

“image_gallery”
end
else…

Im trying to set flag to bypass validation and redirect in update
action. “in_progress” is an attribute of question which is initially
set to false in the edit action.

Thanks

You can do that the same way you would do it in HTML, use a hidden form
field. Rails has a helper for that:

I did try that. For some reason update action does not see
params[:in_progress] == “true” as true. It is ‘true’ in params hash
though. Any other thoughts? Been trying to figure this out all week.

In view:
<%= f.submit “Add image/video”, :id=> ‘add_image_commit’ %>

jQuery sets hidden field “in_progress” to true:
$("#add_image_commit").on “click”, (event) ->
$("#in_progress").val(“true”)

Hidden field IS set to true.

In controller:
def update
@question = Question.find(params[:id])
if params[:in_progress] == “true”
@question.attributes = params[:question]
if @question.save(:validate => false)
redirect_to gallery_path(session[:minisection_id]), id:
“image_gallery”
end
else…

Params hash:
in_progress: ‘true’ commit: Add image/video _wysihtml5_mode: ‘1’
action: update controller: questions

Got it!

if params[:question][:in_progress] == ‘true’

Thanks.
