I am doing controller testing, and I can''t seem to get the create method test to pass when friendly_id is added to the mix. If I comment it out of the model, the tests all pass perfectly. The moment I add it back in, the error looks like this: 1) Error: test_create_valid(BrandsControllerTest): FriendlyId::BlankError: FriendlyId::BlankError

Hello, I wanted to parse some information from a text, where fields are tab separated. When I copy the text into an R session (under emacs) like: mystring <- "field1 field2 field3" the tab character is replaced by a single space! For ex, if I type mystring, I get: "field1 field2 field3" The tabs have disappeared!!! I checked with Python that the text I copied was tab

I'm able to do this as follows, but am wondering if anyone knows a simpler way which still avoids explicit loops? > (mystring <- letters[1:5]) [1] "a" "b" "c" "d" "e" > unlist(sapply(mystring[-length(mystring)], + function(x) paste(x,mystring[(grep(x,mystring)+1):length(mystring)],sep=""))) a1 a2 a3

HI, While I testing some code, I found some problem on Union handling. I've wrte following test code, and it has union assignment. The code's output is from pointerToUnion: chars mystring, length 64 from original: chars mystring, length 8000 It's caused by second char member(charlength) of LongestMember. For union assignment, llvm-backend seems generates assigning each member of

Hi everyone, I am relatively new to rspec and I am running into a wall in testing my views. I have a RESTful resource Contracts with a nested resource of Line_items. I am trying to figure out how to test the "edit" form of the Line_items. What complicates this is the nested routing and how to account for it, and that there is a partial form (_form.haml) that both the edit.haml and

Hello everyone, After running the following code, I obtain this error message. > mydata <- read.table(textConnection(mystring), + header=TRUE, sep=",", + row.names="id", na.strings=" ") > mydata Warning message: closing unused connection 3 (mystring) ===== However, when I attempt to run read.table() again and immediately submit the close() function

I have a matching problem that I cant solve. mystring = "xxx{XX}yy{YYY}zzz{Z}" where "x","X","y","Y","z","Z" basiclly can be anything, letters, digits etc. I'm only interested in the content within each "{}". I am close but not really there yet. library(gsubfn) strapply(mystring,"\\{[^\\}]+",, perl=F)

Hi, I''m a newbie to RoR and have been facing some problem installing RoR on my system. I''m following this guide to install RoR https://help.ubuntu.com/community/RubyOnRails and stuck up at this step Installing Rubygems: To make gem work properly you should write gem''s path to PATH add to ~/.bashrc: export PATH=/var/lib/gems/1.8/bin:$PATH Can anyone help me saying

Dear list, I have a general problem that I really don't know how to solve efficiently in R. Lets say we have a sequence of things, like for instance a string of words, that is stored in a file. We need all the words in a table format, so therefore we create an id for the word, that links the word to a file and the position of the word within the file, like: #In this case a very short file

I''m having problems with class variables.. I have a class: class Content::ApplicantsController < ApplicationController layout "mylayout" @@tab = "mystring" [... the rest is standard scaffold-created stuff ...] and a layout (mylayout.rhtml): [...] <title><%= @@tab.capitalize %></title> [...] And I keep getting this error: uninitialized

I have these two instructions, first one inside some procedure, second one is an outside declaration. Code verification passes and it runs, but incorrectly. Every time I saw such situation coming from c++ compiler, attributes 'noalias sret' appear on both call and declaration. Does such situation make sense, or (as I guess it is) a bug in verifier? I think verifier should match at

Please consider following string: MyString <- "ABCFR34564IJVEOJC3434" Here you see that, there are 4 groups in above string. 1st and 3rd groups are for english letters and 2nd and 4th for numeric. Given a string, how can I separate out those 4 groups? Thanks for your time [[alternative HTML version deleted]]

Hi, I'm having a hard time finding an answer to what I assume is a very basic idea. I'm trying to produce this llvm code using the LLVM api: %myString = alloca [13 x i8], i32 13 store [13 x i8] c"Hello world.\00", [13 x i8]* %myString %tmp1 = getelementptr [13 x i8]* %myString, i32 0, i32 0 %tmp2 = call i32 (i8*, ...)* @printf( i8* %tmp1 ) nounwind A simple Hello

I want to fit a series of lme() regression models that differ only in the degrees of freedom of a ns() spline. I want to use a wrapper function to do this. The models will be of the form y ~ ns(x, df=splineDF) where splineDF is passed as an argument to a wrapper function. This works fine if the regression function is lm(). But with lme(), I get an error. fitfunction() below demonstrates this.

Hi, Is there an easy way to test if a substring exists in a string? I''m using this check: if mystring.index(substring) > 0 but it doesn''t seem to be working.... Thanks! -- Posted via http://www.ruby-forum.com/.

Hello everyone, I use Bob Muenchen's approach for reading in "in-stream" (to use SAS parlance) delimited data within a script. This works great: mystring <- "id,workshop,gender,q1,q2,q3,q4 1,1,f,1,1,5,1 2,2,f,2,1,4,1 3,1,f,2,2,4,3 4,2, ,3,1, ,3 5,1,m,4,5,2,4 6,2,m,5,4,5,5 7,1,m,5,3,4,4 8,2,m,4,5,5,5" mydata <- read.table( textConnection(mystring),

total rails nuby here. I have a table "thumbnails", hence the model Thumbnail. I''m extending the Thumbnail class with a few constants needed for thumbnail cropping: class Thumbnail < ActiveRecord::Base SOURCE_FILE_PATH = "path/to/source" TARGET_FILE_PATH = "path/to/target" TARGET_WIDTH = 100 TARGET_HEIGHT = 100 end Now, in my controller

Hi, i was struggling for a function where only 1 thumbnail should be active and others inactive when clicked on the particular thumbnail. code: 1. view: 2. <script type="javascript"> 3. function PlayVideo_options(videoFile, id) { 4. document.getElementById(id).className = ''video_option active_video''; 5. } 6. </script> 7. 8.
