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 *

Hi, I 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

Hi, I''m looking at using my table headings as links that reload the page and sort it by the field which was clicked on. As is common, if the list is already sorted by the field, it reverses the order. I''m now looking at a good DRY way to do this. I have 3 fields: name, date, race. I''m setting a parameter called so (for sort order) to either "up" or

I''m trying to figure out how to change the order of a list view and it''s obvious to me that I don''t understand what I get from a simple scaffold to know enough to alter it. If someone would be so kind to tell me what this means ... def list @placment_pages, @placements = paginate :placements, :per_page => 10 end @placement_pages, # I am guessing that this

Hi there, Is there a neat and easy way to implement pagination with letters rather than numbers eg : A B C D ... Z Rob

because I am a grasshopper... Now that I can sort my ''list''...is there a logical way of not repeating myself to having essentially the same list view with multiple sorts? i.e. def list_cl # ordered by clients last name @placement_pages, @placements = paginate( :placements, :include => [:client], :order_by =>

I''m trying to create a paginated list that will take note of the "end_date" field in my table. This is what I have: @post_pages, @posts = paginate(:posts, :per_page => 10, :order_by => ''end_date'') in the controller. And for the view: <h1>Posts ending soon</h1> <ul><% for post in @posts do %> <strong>Post Title:

Hey all, I''m using a simple search function. It''s working great except for foreign keys. I have one table pets (id,name,owner_id) and another table people(id,name) owner_id being a foreign key of pet pointing to people name. here it is on the pet controller: @paginator, @pets= paginate(:pets, :conditions =>["name OR owner_id like

Ahoy, I checked the API and did some forum searches but didn''t find anything good on table sorting. Is there a "railish" way to do this? My current method really is lacking (i''m on like rails day 2) <th><%= link_to ''Name'', :action => ''list'', :order => ''name'' %></th>

i''ve figured out how to use the next and previous links with the paginator class but now i''m trying to figure out how to display all the page numbers in between. looking through the rails api, i found paginator.each() but i''m not sure how to use it, or if that''s even what i am looking for. also, is there a way to limit the amount of pages like some sites

I am trying to use pagination with the order option. I am following examples I''ve seen all over the web, but I am getting an error. My code seems simple: def list @upload_pages, @uploads = paginate :uploads, :per_page => 20, :order => ''id'' end Yet I keep getting this error: ___________________________________________

Hello. I call a find_all_by_subject("action") which returns 2 videos and displays them properly. But when I add @video_pages, @videos = paginate :videos, :per_page => 10 so I can paginate the videos, it displays ALL the videos as if I selected list videos. Can someone please tell me what I am doing wrong? Thank you. selectaction.rhtml <table> <tr> <% x = 0 %>

Hello, With default pagination I have this : <a href="/users/infos/3?page=1">1</a> <a href="/users/infos/3?page=3">3</a> but i need this : <a href="/users/infos/1">1</a> <a href="/users/infos/3">3</a> I need to remove the "?page=" parameters and rewrite a little the link ( with a link_to ? )

I''ve been experimenting with Rails over the past couple of days and have come across something that seems harder than it should be. In previous frameworks I have used (WebObjects, php) a full search page (which leads into a list view populated with search results) was part of the CRUD that was either dynamically or statically created after specifying table/object schema. In

Hi all, Best wishes for the new year! :'') I''m very new to Ruby and Rails, and I ran into a problem with the "paginate" function.

Evening folks, I''m new to RoR, and have found some very useful info on this site, thanks.

Hi all, Im trying to get my head around rails and to help along Im working through "four days on rails" as this seems to give a good real world example with multiple tables and relationships (the main thing I cant work out!) Ive got stuck. Some help would be really good here. The controller has this code: def list @category_pages, @categories = paginate(:category, :per_page =>

Hi! It''s rather ruby question than rails... I have a single ''list'' action where i call paginate method. I can receive none, 1 or 2 variables that specify conditions for paginate method. How to write the code so i can call paginate without conditions if all conditions variable are nil, with a single condition if one of conditions variables is not empty and with 2 if
