I got it to work by changing scheduled_end_date= nil to self.scheduled_end_date= nil. I believe these statements should be equivilent. I don''t know Ruby/Rails well enough to know when, if or why that should matter. Can someone educate me please? I want to believe this framework is ready for production work, but silently dropping data is a very big problem. I expect that I''ve

I''m selecting data into a controller and sorting it. The code (in the controller) looks like this: def index @assignments = [] tasks = Task.find(:all, :conditions => ["person_id = ? and actual_end_date is null", session[:user].id.to_s ]) issues = Issue.find(:all, :conditions => ["person_id = ? and status <>

Hi, I''m using TextMate for rails development on OSX, but have reached a point where I need to run in a debugger and be able to step through the code as it executes. I have previously used the Eclipse Ruby plug in and another IDE for ruby development on windows, but never figured out how to run a Rails app in the debugger. How are other textmate users debugging and what else is there on

Hi, I''m trying to use rails to build a model from a database view. I get this output C:\dev\v6\project>ruby script/generate scaffold Assignment ... error Before updating scaffolding from new DB schema, try creating a tab le for your model (Assignment) Is this not possible in Rails? It would be *really* helpful for my application. -------------- next part -------------- An

The new pragmatic Rails Cookbook has a drag and drop sorting recipe. Does anyone know if this works with 1.0? I''ve followed the recipe (i think), and I can drag but when I drop everything goes back the way it was. It seems that the sort logic doesn''t get invoked. I put this code in my view: <%= sortable_element ''task-list'' , :url => {

I am having a bit of trouble with the error. I hava a product and category table and wanting to display the categories in a drop down list. Below is the error I get. Any suggestion on how I can fix this. undefined method `name'' for #<Category:0x3652448> 9: <select name="product[category_id]"> 10: <% @categories.each do |category| %> 11:

in my code i''m calling save on an object. The id gets created as the object is persisted. How can i retrieve that newly created id?

At the risk of being wacked for asking what should be obvious.... I have a data frame with one categorical variable "CAT" and several numeric variables. I want to be able to get simple statistics on the numeric variables by level. For example, just as you can use table (CAT) to get the counts, I'd like to be able to get the means and sums by category. If someone could point me

I have an app that uploads files into the directory RAILS_ROOT/documents/ I tried to access the file for downloading using <a href="#{RAILS_ROOT}/documents/file_name">my file</a>. Rails prepends the controller name to the link so I get <a href=" http://localhost:3000/tasks/show_document/config/.../documents/file_name" What''s the right way to do this?

Is there a way to use form_remote_tag and to upload a file? The default behavior ignores the upload when the Javascript serializes the form to create the parameter list. Basically, i''m just looking for an ajax file upload capability. Any help would be appreciated. thanks. -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi, I'm trying to create a lattice plot with three xyplots in one vertical column. I would like to reduce the vertical space between the charts. My code is below. There seems to be a "between" parameter for lattice.options, but I can't find any examples. Aside from the data setup, the code is below. Can anyone provide an example showing how to reduce the white space between the

Hi, I'm trying to do something simple (I think) with lattice graphics. I want to have three xyplots in a single column, where the x axis for the three is a date range and the y axes are numeric. I tried doing the first chart, and ran into a problem. When I enter: xyplot (date ~ count) I get a well formed plot with the date on the y axis, but when I enter: xyplot (count ~ date) I get:

Hi i installed the latest ajaxscaffolding gem and generated a scaffold. List works fine. Delete deletes, but the update doesn''t show and the busy icon spins indefinitely.

I have a class called Duration that represents a unit of time. It has lots of time-related methods and an attribute that represents the duration in seconds. I want to store it in my db. I had a column type of NUMERIC, so if i save it, rails trys to coerce it to a float automagically and fails. I need to display it and store it as a number but treat it in the middle layer as a Duration so I can

-- apologies if this is a dup - i got a bounce saying the message was unprocessed. Is there a straightforward way to get a table with percents in the cells rather than counts? I've looked at table, ftable, xtabs, and ctab, which did the conversion but returned the results in a single row without labels. any suggestions are appreciated. thank you.

I''ve just started using the unbelievably easy and cool auto-complete feature. Does anyone know if you can make it search only from the start of the string (or from the beginning of each word)? By default it seems to do a complete search of the strings - typing MI returns both "Mike Jones" and "Mary Smith". I have to believe this will be much slower as the number of
