Using a <%= form_tag ... %>, how do I give a form a name, so that I can reference it with javascript? I sure can''t figure this out from the docs... Thanks, Shelby PS - what I am trying to do is just have the focus in the first form field when the form is loaded. There has to be an easy way to do this, but I can''t figure it out... -------------- next part --------------

I''ve asked this before, but never got a working response. I''d like to store an object inside a binary field in my db. So I''d have a class like this class MyAwesomeClass def do_something_awesome ... end end then class MyRecord < ActiveRecord::Base end the table my_record would have a binary field, my_object, that would store an object of

I have a rather complex object with a number of attributes. For a variety of reasons, I would like one view to create the object with only a couple of fields completed, then a second and third view to finish all the fields. I would like the model to validate_presence_of all these fields, since eventually I need them all there, and I would like each page to validate its portion of the fields that

I have a mock object (Person) that is associated with another object (my_object) through a belongs_to association. When I check whether my_object is valid (my_object.should be_valid), I am getting an error like the following: Mock "Person_6338" received unexpected message :marked_for_destruction? with (no args) Checking the list of methods on the mock,

I have a database field called dates in which I am trying to serialize an array of DateTime objects. When I unserialize them, they are coming back in as Time objects. I know this, because I am getting errors that say "comparison between Time and DateTime failed. Why is this happening? Is there a way to prevent it??

I need to do something with about 100 of them (schedule manually) I say I should just mark them with a boolean when I have scheduled them. (manual == true) My son says I should pull them out of the entries table and copy them to new objects (lets call them "manual" objects, and store

Hi All, I''m trying to use a form to upload a photo that I will save using attachment_fu. I''m very new to Facebookr so I apologize if this is covered somewhere, but I''m kind of stumped.

I''m studying the Agile Development with Rails book. In the chapter that first sets up the depot application (page 68), there is this bit of code from a view: <% for product in @products %> <tr> <% for column in Product.content_columns %> <td><%=h product.send(column.name) %></td> <% end %> etc... I am trying to absorb both Ruby and

Let''s say I have an application and I want to create an admin program that will show me who is currently online using the application. I don''t know the best way to do this. Assuming I am storing my sessions in the default PStore, I don''t suppose there is any method that lists all the active sessions, is there? The only way I can think of to do this is to setup a

Hy guys, Inside my app I have a form which contains user information. Sometimes a have a form with a text_field as above: <%= form_remote_tag(:html => { :action => url_for(:controller => "my_controller", :action => "my_action") }) %> <%= text_field(''my_object'', ''my_parameter'', :maxlength =>

Reading the Agile book, I can''t find a single command to save a collection. The save command seems to operate on only individual objects. Lets say I have a collection that I have received from a find_all command. I want to go through and change some attributes in various objects in the collection. Then I want to resave the whole collection back to the database. I don''t think

The new "pending" example feature reminds me of a feature I''ve been bouncing around in my head, to aid in refactoring. Often, when I''m changing existing behaviour, I know that certain aspects of the old behaviour should change. Imagine changing the "it" method to perhaps "not" or "old" or "removed"... The behaviour would be to

I''m trying to get a collection_select generated Drop-down box to display two fields from a table (first name & last name); however, I am having trouble concatenating the symbols. It appears as though any code I put in the 5th argument for collection_select is processed prior to executing the collection_select method. The code executes successfully with 1 symbol in the 5th

I am confused about ruby fast C bindings. Does the command: gem install mysql install these? Is this page: http://www.tmtm.org/en/mysql/ruby/ the home page for these bindings? If so, it gives no instructions about installing them with using gem. Wondering if this is all the same??? Thanks for any help...

I know there have been threads on this before but I was thinking shouldn''t multiple collection_select automatically update habtm relations when you update_attributes? In order to get multiple collection_select to work I use: collection_select(:user, :group_ids, Group.find(:all), :id, :name,{},{:multiple=>'''',:name=>''group[id][]''}) In fact if I
