Pass variable to action

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.

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) -> # User clicks "Add image" button. $("#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.
