Hi guys, I''m facing an error trying to run my app as mongrel_service, hope those who have faced similar issue can help to shed some lights.

I have a new @offer that needs to generate a document if saved. But that''s all or nothing: transaction do @offer.save! generate_document end # handle exceptions if needed If save! fails everything is fine, but if generate_document raises an exception @offer is left as a model with timestamps, id, which is not a new_record? anymore (though the database was

I have two objects, QuoteInput and Insured. QuoteInput has one Insured and Insured belongs to QuoteInput. I don''t understand what I''m seeing. I assign an Insured to a QuoteInput. The Insured object has invalid data. I call save! on the quote input. QuoteInput has no validations. I expect two things to happen - 1) an exception should be thrown, indicating that there was a

Hi all I want to overwrite the push method (which is an alias of <<, the same as concat) of collections, and there I want to test if :uniq is set to true in the relationship. If so, the method should check if the passed object is already related to the parent, or not (only then it will be added). But I just can''t find the original code of this method, so I could overwrite

Ahhrg List, there was a hitch in the previous code. Updated and functional version follows after my initial question: I am trying to randomise a dataframe with mixed factors/numeric variables and return a new (randomised) dataframe with the same columns (as factors/numeric). simgap<-function(x) { ma<-max(x) mi<-min(x) Xout<-runif(length(x),min=mi,max=ma) return(Xout) }

Hi List, I have recently upgraded to opensuse10.2 and R 2.5 (compiled from source). Now, whenever I use plot the y-axis and labels are black blotches while x-axis and labels are fine. Using demo(graphics) this occurs with plot/boxplot/hist/pairs/coplot but not in the pie graphs and in the "The level of Interest in R" plot, which uses axis to define the y-axis. I presume this has to

The last thing that I read about it was: Steve Underwood [steveu@coppice.org] wrote on Sep 3: >> Is E&M designed to work with the E1 driver code? I think probably not.

Thanks to Edzer and Roger, I can now plot with increased font sizes. However, jpeg still does not reproduce these, nor does it show up in high quality. What I would like to do is produce some highresolution jpegs. Any help would be appreciated Thanx Herry R2.4 on Mandriva 10.2 linux.

Hi list, I am trying to print a rgl scene.

When you define belongs_to in a model, you can either access association or association_id. I was wondering how Rails would handle things if you set each one to be different. I made two simple models: class Foo < ActiveRecord::Base; end class Bar < ActiveRecord::Base belongs_to :foo end Now here''s a script/console session. >> f = Foo.create => #<Foo:0x270ec10

Dear list, I am having troubles increasing the fontize when plotting a variogram{gstat} and its model (vgm) with plot and using jpeg(). Also the resolution in the jpeg call does not work. I am using R2.4 on Mandriva 10.2 linux. I can change fontsize with cex.axis in a normal plot, so I presume it has to do with plotting the variogram model. Any help on how to increase the font size and
