Hi
I need something like :
<% obj = params[:obj].find(params[:obj_id]) %>
<textarea id="mce_edit" style="height:430px;
width:100%;">
<%= obj.params[:obj_method] %>
</textarea>
in a partial. params[:obj] and params[:obj_method] are strings like
TrstSysPage, title. params[:obj_id] is number and is only working for
the rest I got
undefined method `params'' for
#<Enumerable::Enumerator:0xb4b38b48>
Extracted source (around line #17):
14: <body style="background-color : #AFAFAF; padding: 10px 10px 0
10px;">
15: <% obj = params[:obj].find(params[:obj_id]) %>
16: <textarea id="mce_edit" style="height:430px;
width:100%;">
17: <%= obj.params[:obj_method] %>
18: </textarea>
19: <p style="padding: 15px 0 0 10px">
I''m stuck :)

(Repeat with all other values for :obj_id ;-) Note also that you don''t check for any exceptions (such as ActiveRecord::RecordNotFound or NoMethodError) -Rob> > <textarea id="mce_edit" style="height:430px; width:100%;"> > <%= obj.params[:obj_method] %> > </textarea> > > in a partial. params[:obj] and params[:obj_method] are strings like > TrstSysPage, title. params[:obj_id] is number and is only working for > the rest I got > > undefined method `params'' for #<Enumerable::Enumerator:0xb4b38b48> > > Extracted source (around line #17): > > 14: <body style="background-color : #AFAFAF; padding: 10px 10px 0 > 10px;"> > 15: <% obj = params[:obj].find(params[:obj_id]) %> > 16: <textarea id="mce_edit" style="height:430px; width:100%;"> > 17: <%= obj.params[:obj_method] %> > 18: </textarea> > 19: <p style="padding: 15px 0 0 10px"> > > I''m stuck :) > -- > Posted via http://www.ruby-forum.com/.Rob Biedenharn http://agileconsultingllc.com Rob-xa9cJyRlE0mWcWVYNo9pwxS2lgjeYSpx@public.gmane.org --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I use this just for edit some html data with mceEdit. All params comes from regularly checked edit form, but I needed a new screen/window for those text fields :) Thanks again I''ll try tomorrow .
