similar to: another select_list question - bad bad booleans

I want to use select form elements to choose between boolean options. How can I have it default to true and still display the persisted value (either true or false) when editing an existing object? I guess booleans default to false by default so its not obvious how to recognize when it''s a real ''false'' that the user set or default false because the value was null.

I have a view with a form and i want to be able to process the button selected in a controller - not sure how to do this. The form does not map directly to a model - all I want to do is be able to pass back the selected button and know which one it is. So, i have a form and several radio buttons - the submit (not shown) takes me to the process_answer action where I want to determine which

I have a simple Yes/No selection list that I am using in a number of places. Thinking that I could DRY things out a bit, I added it to application_helper.rb ... YES_NO = [ [ "Yes", true ], [ "No", false ] ].freeze So I figured I would use it there instead of in each model.rb where needed. anyway, in webrick screen, I am continually seeing this...

I have 2 radio buttons like this: <%= radio_button ''group'', ''public'', true %> <%= radio_button ''group'', ''public'', false %> They hold the correct values when viewing the @group object.

Hello- I would like to know what the suggested practice is for having multiple submit buttons on a relatively complicated input page. Let''s use the example of a Contact. There is lots of info there, including name, address, phone number. There is also a list of "contact associations" which can be modified on the same page. Ideally, the user could have one

Hiall, Unfortunately I just can''t find out how to setup a default selected value when using collection_select. My call is like so: <%= collection_select(:consultant, :lastname, @consultants, :id, :lastname, { :selected => @current_consultant.id } ) %> which is not working, I debugged so far that I know that @current_consultant.id contains the correct value. Any tips? cheers

Hello, how can I check if a destroy was successful? Is the object only frozen if deleted or do I have to do an additional find to see if there is a record left? What happens if an after_destroy callback returns false? Is there always a rollback? Markus

Apart from that it''s perfect! :) Cheers, Pete -- Posted via http://www.ruby-forum.com/.

Howdy folks, As I was putting together a rough form for a rails app, I got to thinking how much smoother (in my siytuation) a little calendar widget would be than the default date picker selects. Does anyone know if such a thing exists ? I suspect it would have to be somewhat designed with rails in mind to populate the right kind of post params for convenient use at the controller end.

Hello, The problem I am having is I have a form where a user can edit their data that does not include their password. I have another form that I allow them to change their password. Both forms use the before_update method that hashes the password. There is no password in the first form. Am I making this too complicated? How do I call the hash_password for only the second form? Both forms use

I''ve got a fairly basic problem here that I''m hoping there is an easy solution for. I have a chunk of html code that I want to truncate to a given length... say 20 characters or so. If I use the ''truncate'' helper function I end up with unbalanced tags. For example. <a href=www.someplace.com>A really long string of words</a> becomes <a
