Question

I’m trying to achieve the following, by pushing a button on a page the user to get a random item from the database which will be showed, but will have an attribute editable. The problem I hit into, is the following I don’t know how to pass an random id(valid in the database), to be rendered in my partial, but still to be able to update the specific attribute.

Problem from the title:

  SyntaxError in Tasks#main

I was trying to pass the rand_task output object to the _rand_show.html.erb and afterwartds call a new editable form only for the attr i’m intressted in by the id

form:

<%= form_for(@task = Task.new) do |f| %>
  <div class="field">
    <%= f.label :name %><br />
    <%= f.text_field :name, :disabled=>true %>
  </div>
  <div class="field">
    <%= f.label :category %><br />
    <%= f.text_field :category, :disabled=>true %>
  </div>
  <div class="actions">
    <%= f.submit %>
  </div>
<% end %>

random method:

def rand_task
    if params[:id] == 'random'
      @task = Task.order('RANDOM()').first
    else
      @task = Task.order('RANDOM()').first // if not  i get a nill related error.
    end 
  end

Please help why do i get the above mentioned error? IS the concept i’m thinking about wrong?

Answer 1

<%= form_for (:task, :url => {:action =>'rand_task'}) do |f| %>
            ^

The problem is the space between form_for and (. If you remove the space it should work.
