ruby on rails - Instance variable not showing in view forms -

i'm having issues getting instance variable show in views. i'm setting using private method, , i'm using before_filter ensure can access in 2 places need it. however, instance variable not showing in view, let alone having needed action.

in controller have

class userscontroller < applicationcontroller before_action :set_user, only: [:show, :edit, :update, :destroy] before_filter :set_form, :only => [ :edit_password, :edit_email ] ... def edit_password  @user = current_user   set_form('password')  end  def edit_email   @user = current_user   set_form('email') end ... private def set_form(edit_type)   @form = edit_type end  

here view file

<h1>edit account</h1>  <title><%= @form %></title> <% if @form == 'email' %> <%= render 'edit_email_form' %> <% else %>  <%= render 'edit_password_form' %> <% end %> <%= link_to 'back', user_path(@user) %> 

i'm not sure else need able use instance variable in view. i'm wondering whether it's still possible access instance variable in update statement after? appreciated!

there's no value in setting set_form in before_filter, you're calling in methods.

you need explicitly render view file... don't see you're doing that. if form called (for example) edit_value.html.erb 2 edit_... methods need have

render :edit_value 

instance values not available in update statement. when update nothing available except information submitted in form or url, or saved in session hash, or persisted database.
