Is there a standard practice for providing a UI into HBTM relationships? I have a model User, and a model Training, and I need to manage both relationships -- show me all the people that have training X, but also show me all trainings user U has. And, of course, "Lookup this user and then add/remove trainings for this person" or "Lookup this training and add/remove

What is the rails idiom for submit buttons on forms? All other field types have helpers, but button_to creates its own form, so should not be used. I''ve looked in "Agile Web Dev. with Rails" but can''t see what I should do instead. Is this "difficult" because it runs counter to AJAX type forms? And, related, is there a way to ensure that hitting return in

During one of my controller actions I want to call an external machine before I do anything. It''s not a real web service, more like a REST-style thing where I''ll just be tweaking a servlet running on another machine and sending it some data. Does Rails give me anything to work with for doing that? I read the web service stuff but it''s overkill for what I need. I

I''ve got a nice XML view of my data that works just fine when I call it from the browser. Now I''d like a different controller method to take that XML and write it to the file system. Since the XML view lives in an RXML file, is there a trick to telling the controller "Get your output into a string" instead of writing it back to the browser? After writing it out

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:

My Alert object has_many Links. I''ve got the whole system setup where, once I have the Alert object created, I can use a nice form_remote to show the user all the Links currently attached, and add more. But the form itself starts out with 0 links. What I''d like to do now is construct the form with a couple of default "Place link here" objects in the array, and

I''m curious, Christian Neukirchen has released test/unit[1] that seems to mirror much of RSpec, but built on Test::Unit, so in some ways less brittle from a Rails-integration perspective, and also allowing you to mix the two together as appropriate. So, has anyone made an informed comparison? I''m new enough that I don''t really know the finer points yet. The syntax is

So I''ve inherited a legacy application and I''m trying to work around the edges as I put an admin tool interface on top of the existing code base. I install Devise for user authentication, since I''ve used it in the past. I change none of the default code. And yet, on successful sign in, I get an error: Render and/or redirect were called multiple times in this action.

I am applying Rails to an existing schema and not sure how much the existing developers will let me go in and rename things. So I need to discover the limits of what I can change with Rails. I''ve found set_table_name and set_primary_key, which have been very useful. If I have a "foo has_one :bar" relationship, but then in the bar table my column is named "fooid"

Does anybody know how to paginate a find_by_sql query? Unfortunately I need to paginate a query which is next to impossible for ActiveRecord or just too much of a pain to implement. So I''m using find_by_sql. However, I anticipate a large number of rows returned eventually. So I may need paginate. Does anyone know how? Thanks Phillip Novess http://primalart.net

Googling for this has not solved my problems. Is there a particular site that is recommened for its examples and tutorials on Rails'' AJAX capabilities? I know exactly what I want to do, just not how to do it, and am looking for some code to pore over. 1) I have a dropdown that represents the name of an image in a library. When the dropdown value is changed, I would like to refresh

I''m trying to map Rails to an existing schema, and having a bit of a time of it. I''ve got a table Content, and I''ve got a table Review, which is a type of content. So content has an ''id'' field, and Review has a ''contentid'' field. Not all Content has a Review, but all Reviews have exactly one Content. How do I represent this?

Not sure if this is old news or not, but it would appear that both the Ruby Cookbook and a Rails book are now available for purchase at O''Reilly Rough Cuts (something akin to PragProg''s beta book program): http://rubyurl.com/nHz http://my.safaribooksonline.com/?mode=roughcuts&srchtext=ROUGHCUTS I haven''t tried them yet, but it definitely seems worth checking out.

I''ve had a number of occasions now where I want to find something in my model that is not on the primary object. For instance I''ve got a class Alert that has_one Status. Status has a "label". I want to find all of my Alert objects and order the results alphabetically by status label. Can I do that without going into SQL? Right now I find myself doing an

I want to be able to find items according to various params - category_id, member_id, type_id, rating, etc. What I have now is something like: if(@params[''category_id'']) @items=Item.find(:all, :conditions=>["category_id=?", @params[''category_id'']) elsif(@params[''category_id''] and @params[''member_id''])
