Hi everyone, I''m working on my first Rails project and I''d like some input before I get started coding in earnest. My previous Web app development experience has been in standard Python CGI and Zope. I''m here to find out more about Rails. I work in technology in an average-sized school district (8,000 students) in Minnesota (USA). One of the problems in our

Hi! If i have an object it''s easy. But i''m making a simple contact form and i check if email address is correct. If it''s not i redisplay the form with the info that there was an error (should i use redirect_to or render :action? what''s the difference?), but all previously submitted data is lost. I tried creating variables using names of the form fields, but

Hi all, is there a way to override the validation methods so as to avoid the div.fieldWithErrors divs from being created on the redisplayed form? Many thanks in advance, Nicky

I want to build a simple calculator with 1 form and a results page. The form will be redisplayed with an error message upon an invalid value entered. I won''t be using any database/active record for this. The problem i have is when i return to the form page i want to redisplay the values already entered in the form fields. Should i use text_field (which seems to be tied to a model) or

I am playing around with the Agile Rails development book again and thought to see what effect, if any, placing a doctype declaration at the top of an rhtml file would have. When I insert any of the three standard forms of such declaration at the top of app/views/store.rhtml the product image disappears when the web page is redisplayed. The error logged in log/development.log is: >

I am trying to create submenus, or more specifically a single submenu, using PXELINUX and the menu.c32. I have a tftp share with a basic config: / (root of tftp) pxelinux.0 menu.c32 /diskdiag (dir) /diskdiag/dskdiag.0 /pxelinux.cfg (dir) /pxelinux.cfg/default /pxelinux.cfg/dskdiag one of the menu items in /pxelinux.cfg/default is as follows: LABEL DISKDIAG MENU LABEL [^B] Disk Diagnostics

Hi, Something has been bothering me for a long time and I''d like to know what other think about this common situation with Rails. Someone is looking at http://example.com/user/new where there is a form that POSTs the data to the user/create action. The controller might look like def new @user = User.new end def create @user = User.new(params[:entry]) if @user.save

I''m trying to assign a parent foreign key value using collection_select from my child "new" form. The problem I''m having is if I do not make a selection, I get the following error instead of the Rails validates_presence_of error: You have a nil object when you didn''t expect it! You might have expected an instance of Array. The error occurred while evaluating

I''m creating an AR object in my controller and then attempting to add error messages to it: if (master_storeids.nil?) @item.errors.add_to_base ''No store is selected'' end This works without error but when it comes time for AR to add the record, it apparently initializes the errors because the message that I added does not cause the AR add to fail as you would

I am trying to write some simple code post a form, update the database and do some validation. I have 2 problems: 1) The validation fails but I can''t get hold of the error message 2) I can''t get the form to redisplay the previously entered data for the user to correct. I have 2 controllers: user and holiday. A user can request a new holiday by filling in a form. I have a

I have a partial, it''s a shopping cart display, it''s designed to appear on several different pages of my site. One of the buttons on the shopping cart empties the cart, and then I want the calling page to redisplay. In other words, the cart controller needs to return the visitor to the same page -- however since the cart could appear on any given page, this has to be

Hi, I have the binned data (observed and generated from model)  that I would like to test using the anderson-darling goodness of fit test.  But I'm not sure which package in R to use. I tried ad.test(...) but it does not recognise the test by Vito Ricci in FITTING DISTRIBUTIONS WITH R   > ad.test(hist_hume_beec[,1],hist_hume_beec[,2]) Error: could not find function "ad.test"

Hi again... One more item.. the file_column plugin uses a tmp directory inside the /public directory to store a temporary uploaded item. But it looks like this folder is just going to grow and grow. Is there some way to clear this out or not cause this to happen? Thanks once again! -- Posted via http://www.ruby-forum.com/.

Hello all, Would somebody be kind enough to show me how to do a KS test in R for a lognormal distribution with ESTIMATED parameters. The R function ks.test()says "the parameters specified must be prespecified and not estimated from the data" Is there a way to correct this when one uses estimated data?

Hi, I'm trying to run an anderson-darling test for normality on a given variable 'Y': ad.test(Y) I think I need the 'nortest' package, but since it does not appear in any of the Ubuntu repositories for 2.10.1, I am wondering if it goes by the name of something else now? Thanks -- View this message in context:
