similar to: Providing limited CRUD access to arbitrary tables through a web interface.

After sending this I realized that this was a Ruby not Rails issue - but the answer may be interesting for those who choose Marshal over Serialize. So, to close this off I don''t know why marshal.dump wasn''t ''dumping'' all attributes, but adding custom marshaling to PDate did the trick. ala, + def marshal_dump + dumped_obj = [date_precision, ajd,

I have a data set like this: > head(FormatedData) ID Target Actual Date Time 1 2030 0 -57.0 12/20/08 17:03:00 2 2030 90 90.0 12/20/08 18:41:00 3 2030 45 43.8 12/21/08 14:36:00 4 2030 0 -23.8 12/21/08 19:30:00 5 2030 90 90.2 12/21/08 21:48:00 6 2030 45 48.6 12/22/08 13:02:00 I wan to convert the format of Date and Time, so I did this: pdate

Dear R-devel: I could use some advice about matrix calculations and steps that might make for faster computation of generalized inverses. It appears in some projects there is a bottleneck at the use of svd in calculation of generalized inverses. Here's some Rprof output I need to understand. > summaryRprof("Amelia.out") $by.self self.time self.pct

SUPERMIN_KERNEL and SUPERMIN_MODULES don't work to guestfish. Since guestfish sets --if-newer parameter to supermin, so the environment variables are not used under the following conditions. - the output directory exists and, - the dates of both input files and package database are older than the output To solve that, rebuild the output it when SUPERMIN_KERNEL or SUPERMIN_MODULES are

Greetings, I first want to say that this problem is happening with the Runt gem. This may is likely an implementation issue between Marshal and Runt. While I''ve simultaneously filed this problem with Matt Lipper, I''m also hoping someone here can can guide me a little - either in implementation (usage of Marshal), or to aid me to fix Runt to support Marshal.

Add a function for each mode to return the list of potential outputs, so that the existance/timestamp checks done for --if-newer can take those into accounts. At the moment both modes return no outputs, so there is no behaviour change. --- src/mode_build.ml | 7 +++++++ src/mode_build.mli | 4 ++++ src/mode_prepare.ml | 9 ++++++++- src/mode_prepare.mli | 4 ++++ src/supermin.ml | 9

With most models, almost always I find myself writing Search/Find actions. When I view a Listing of a model, I want to look at another record or set of records. How nice it would be if I can do a query-by-example while viewing a Listing, or during Show/Edit/Create. Would be nice if Search becomes another act in the scaffolding magic. This wish has been expressed here before. Since then, has

For edge rails there is a Crud generator. There is also a CRUD controller that is out there from which you can inherit your other controllers (see http://geekonomics.blogspot.com/2006/07/crud-and- shared-controllers.html) This got me thinking about Crud controllers in general. As far as I know, the generator can''t produce crud classes which are nested (i.e.

?ginv provides 'Modern Applied Statistics with S' (MASS), 3rd, by Venables and Ripley as the sole reference. I happen to have this book (4th ed) on loan from our library, and as far as I can see, ginv is mentioned there twice, and it is *used*, not *explained* in any way. (It is used on p. 148 in the 4th edition.) ginv does not appear in the index of MASS. ginv is an implementation of

Hey guys, I''m trying out the new RESTful bits in Edge Rails, and am having a bit of trouble wrapping my brain around certain things. For instance, say I have a page that is separated into sections with tabs at the top. I want to replace divs on the page with RJS. Now typically before I''d have a method on the controller that rendered an RJS template to accomplish this.

Hi all .., I have a list of 7000 dataframes with similar column headers and I wanted to add a new column to each dataframe based on a certain condition which is the same for all dataframes. When I extract one dataframe and apply my code it works very well as follows :- First suppose this is my first dataframe in the list > OneDF <- Mylist[[1]] > OneDF ID Pdate

I''m rewriting an application with the intention to use the elegant CRUD and REST design principles as outlined by DHH in his RailsConf Keynote[1]. The question is: how do you use those principles for an application that is of a sequential nature? The application works much like an MS Windows wizard: user begins at screen foo. After doing (or not) some stuff in screen foo, he is taken to

I have a few simple controllers doing plain, simple crud in a standard way. now it''s not very DRY to write a funtcional test for each controller, since they are all doing the same (apart from a few variable names, but that could be easily inflected or so). is there a way to do this? e.g. does inheritance work with tests, so i define a base test first, inherit my other tests and add a few

Hello, I was wondering if there was any automated (may be scaffolding) way of exposing Model CRUD via web services. I found this ticket for django, but nothing for Rails. http://code.djangoproject.com/ticket/115 Thanks in advance for your opinions and suggestions.

Let''s say I have the model class Reader and Magazine, connected by join model Subscription. It looks something like this class Reader < ActiveRecord::Base has_many :subscriptions, :dependent => :delete_all has_many :magazines, :through => :subscriptions validates_presence_of :name end class Magazine < ActiveRecord::Base has_many :subscriptions, :dependent =>

Hi, I am just starting of in rails. I am trying to understand the features of rails and I have this burning question. (and search is not available now): Apart from relying on the automatic CRUD sql script produced, is there a way I can create my own sql script ex: with many joins between exixting tables (for reporting ). All I need is to declare the custom query and place the result in a

In case we need to check whether the appliance must be rebuilt, check also the timestamp of the outputs of the mode, i.e. the kernel, initrd, and root files. This way, when either of these files does not exist or is older than the package manager DB we can rebuild the appliance. Add a simple test to verify this behaviour. --- src/mode_build.ml | 12 ++++++++ src/mode_build.mli
