i have a table of data in my application. i would like to be able to sort the data in the table by clicking on the column header. the way i was thinking i want to do this is just by making a ''sort'' action, and then calling the sort action from each link in the table header (passing the respective column name). it doesn''t seem to be possible to pass parameters to an

I have a category list which the customer wants administratively to define the sort order, instead of alphabetical or whatever. The obvious approach seems to be to put a sort_order int on the record and use this as the presentation sort order. Then to shift the item up in the sort order to swap the current and the prevous item in the sort_order. Does this seem like a sensible approach, or is there an easier way? _______________________________________________ Rails maili...

...am trying to implement a few queries now. What are good ways to do this? Right now, I have a list page that does sorting and can carry out a generic pagination request. @user_result_pages, @user_results = paginate(:user_results, :per_page => 20, :conditions => @condition, :order_by => @sort_order) I create @sort_order earlier in the list function. The problem I am having is with ''@condition'' I''m not sure what''s the best way to create this. There are a number of options that my user may select: 1. date > ... 2. range of dates 3. specific dates 4. n...

Hi! I''m looking for a good tutorial that explains the main points of performing queries with Rails. I do have AWDWR and have read the section on ''find'' but I''m looking for something that goes into more detail on how to perform queries across tables. Abstracted from my current application, this is an example: * person has_many sites * site has_one room *

My problem is that elements that were included in my site with innerHTML can´t be sortable because the DOM doesn´t know that these elements are there. Has anybody a solution or an idea to this problem?

Before I start down this road, has anyone done a breadcrumbs implementation they''d be happy to share? Thanks Chris T

I just updated to rails (via gem) and now all my .find..... methods give me "wrong number of arguments(3 for 0)" with the exception of find_by_sql which works fine but I want to avoid for obvious reasons. I''ve tried simplifying everything down to the bare minimum Priorities.find(1) and I printed out Priority.table_name to confirm it was still correct. What gives? Did I

Starting to feel more confident and code is DRYing up nicely, but I''ve hit a brick wall here and hoping someone can help me. I''ve got a module, TrustRanking, which extends a number of model''s instance methods, and I want to extend their class methods too, but I can seem to work out how to do it. Simply including the module from the class works a treat for the

Me: not experienced with Rails or Ruby, Problem: Ubuntu 9.04 server in my shop ...couldn''t get Apache2.2 + Passenger + Rails to work for Redmine.

Goal: run Redmine on a server that also runs PHP
