similar to: Can you unserialize an object from the db?

I''m using the runt library [1] to do some temporal expression matching. I want to keep the expression in a binary field in my db. I figured that then in order to do the fixtures, I''d need to do some erb in the yaml file. So I came up with this: onetime: id: 1 name: One Time description: This event occurs only one time. timex: <%= REYear.new(7) & REMonth.new(24)

Hi, While debugging a network server I'm developing I noticed something unusual - call to unserialize() resulted in an error about loading a namespace. I was a bit taken back by this - why should unserializing an object cause a namespace lookup? Are there any other side-effects of unserialize() that I should be cautious about? I've been digging through the R_Unserialize() call, I

I stumbled upon the following: f <- parallel::mcparallel(raw(0L)) parallel::mccollect(f) # $`77083` # NULL but f <- parallel::mcparallel(raw(1L)) parallel::mccollect(f) # Error in unserialize(r) : read error traceback() # 2: unserialize(r) # 1: parallel::mccollect(f) (restarting because the above appears to corrupt the R session) f <- parallel::mcparallel(raw(2L))

I mentioned this in another thread, but I''ve got a formal request now. After reading tons of stuff about REST, I don''t really get it. I need to see an example. I''d like someone to write up an example blog app with these requirements - RESTful using the simply_restful plugin (or edge rails) - allows posting of comments to articles - has categories for posts No need

Hi all, I am not able to export an ALTREP object when `gctorture` is on in the worker. The package simplemmap can be used to reproduce the problem. See the example below ``` ## Create a temporary file filePath <- tempfile() con <- file(filePath, "wrb") writeBin(rep(0.0,10),con) close(con) library(simplemmap) library(parallel) cl <- makeCluster(1) x <- mmap(filePath,

Hi folks, I've attached a patch to the svn trunk that improves the performance of the serialize/unserialize interface for vector types. The current implementation: a) invokes the R_XDREncode operation for each element of the vector type, and b) uses a switch statement to determine the stream type for each element of the vector type. I've added R_XDREncodeVector/R_XDRDecodeVector functions

I''m writing a simple app that doesn''t need to use a database. I added :active_record to the config.frameworks -= line in environment.rb file. This lets me run ./script/generate fine without complaining about no connection. However if I try to run a functional test, it complains about no connection being established. Well...I don''t want a connection to be established.

Hi all. I''m a new convert (or at least I want to be a convert) to Rails. I''ve got the book, have read it, done bits and pieces of the demo, and tried to apply it to a rather complicated DB I''ve got here. I''ve got a ton of questions, and before I bore everyone here, is there a dedicated forum for Rails newbies to get help? Yak -- Posted via

I need to split some information up between two servers, and wanted to use REST for it. I can write the REST server really easily...but I don''t know how I can actually use it. I downloaded Rails trunk to mess with ActiveResource, but it seems that it doesn''t have create functionality enabled yet. Is it possible to use AR fully? If not, what''s the best way to consume

How does one do a SELECT MAX query in rails? I''ve searched and searched and tried lots of things with no luck. I want to implement "SELECT MAX(column_name) from table_name and have it return the maximum value from column_name. I just need to get that one value, not the whole object... Thanks for any ideas...

I''d like to start gathering information/debating on the advantages/disadvantages of using it "should ..." vs other techniques. Dan North explained why we should use should: http://dannorth.net/introducing-bdd/ I used to use it "should ..." for the projects I was on, until I was challenged by a fellow developer who started using it with an active voice.

rspec_resource_generator ======================== By Pat Maddox Use this generator to generate RESTful scaffolding with RSpec specifications. Syntax is exactly the same as the scaffold_resource generator: ./script/generate rspec_resource ModelName [field:type field:type] When you run this generator, it will create a migration, model, and model spec file. In addition, it gives you a RESTful

Here''s a controller spec I wrote, it''s for a very simple RESTful controller (well, aren''t all RESTful controllers simple? :) I''ve created a couple spec helper methods to refactor some of the common code...for example, require_login_and_correct_user creates two specifications: one for when the user isn''t logged in, and one when the user is logged in but

I''ve seen a number of posts where someone says, "What happens if you just run dispatch.fcgi directly?" Every time I do it, I get a "500: internal server error" message. I was just curious if that''s what''s expected running it directly. I assume so, because my apps all work fine, but that''s always bugged me. Pat

I created a project, made a migration, generated scaffolding...start up webrick and I get nothing. To simplify things, I just started another project and generated a controller, still getting nothing. The index page loads fine, but nothing beyond that. If I go to anything that should give me a 404, the page is just blank. The Webrick console just says a 500 (nothing explaining why), and
