Hi everyone this is the error that''s been killing me, please tell
where i am missing.
I have upgraded my rails version from 1.2.3 to 2.3.2 and have
installed active_scaffold plugin, since then this error started which
was not there in older version.
This is the log output:
Processing AccountController#consumer_home (for 122.167.8.236 at
2009-07-31 09:02:22) [GET]
NoMethodError (undefined method `[]'' for nil:NilClass):
app/controllers/account_controller.rb:566:in `paginate_by_sql''
app/controllers/account_controller.rb:623:in `consumer_home''
Rendering /home/v8354a/public_html/projectbidding/public/500.html (500
Internal Server Error)
I have paginate_by_sql function in application_controller.rb file
which is shown below will call Paginator class.
def paginate_by_sql(model, sql, per_page, options={})
if options[:count]
if options[:count].is_a? Integer
total = options[:count]
else
total = model.count_by_sql(options[:count])
end
else
total = model.count_by_sql_wrapping_select_query(sql)
end
object_pages = Paginator.new self, total, per_page, @params
[''page'']
objects = model.find_by_sql_with_limit(sql,
object_pages.current.to_sql[1], per_page)
return [object_pages, objects]
end
Please help

Looking at the code though I guess it is one of the lines containing options[:count] or maybe @params[''page'']. The error is undefined method `[]'' for nil:NilClass which would suggest that maybe options or params is not set. If you can''t see the problem by inspecting the code you could try using ruby-debug to break in at the appropriate point and have a look at what is going on. The rails guide on testing applications is good. Colin

From the trace I would have expected line 566 of account_controller.rb to have been in the function paginate_by_sql and the call to paginate_by_sql to be at line 623 (in consumer_home). Whatever the answer to that however, I suggest you have a look at the last parameter of the call, is that an empty string? The function appears to be expecting a hash. Though I am not sure whether that would give the error seen. Did you try using the debugger? By the way I believe that top posting is rather frowned on in this list.
