I'm still going through "Agile Web Development with Rails" (Beta version), and I'm confused as to why some code in the book is not working for me. Following their example code in the book, I created code like so:
Code:
$ rails demo
# ...
$ cd demo/
$ script/generate controller Say index hello goodbye
exists app/controllers/
[code]...
After starting the server, I can view the index view and the other views just fine. But then I have trouble if I add this code to any of the view html templates:
Code:
<p><%= link_to "Hello", say_hello_path %></p>
I'm told this is supposed to generate a link to the say/hello view. But instead I get an error message like so:
Code:
undefined local variable or method `say_hello_path' for #<ActionView::Base:0xb6ce3090>
If I edit it to
I'm going through the Beta version of "Agile Web Development with Rails - 4th Edition". But I'm having difficulty with initial configuration on my Gentoo box. I started like so, basically following the book:
Code: $ rails testrails $ cd testrails $ script/generate controller Say hello goodbye
Java applet not loading image with relative path(e.g. images/1.jpg) but loads image with absolute path(i.e. from /root/user/images/1.jpg) . This is a problem when i want to host the applet on web server
Does anyone know how to get the path with a inode number by C programming? Or can I get the absolute path without giving a "path" but a inode number by C?
like this: get_path(unsigned inode); not such this function: getcwd(".", xxx); taowuwen@gmail.com
knows how to remove an app (or in this case, a test/learning app) from Rails 3?I could just delete the folder, but I'm worried it will leave annoying residual files around that I will never find (database, server, configurations, etc...).Especially since I'm new to linux, I don't even know how to be aware of what files may have been generated/changed as a result of making a new rails app.
I have thousands files in thousands subfolders. All subfolders are named differently, but all files named like:
I have to replace "AAA_000" with the path of the file.
For example if I have a file AAA_000_001.tif in Foled/sub1/sub2, I have to rename AAA_000_001.tif to Foled/sub1/sub2_001.tif (or Folder_sub1_sub2_001.tif)
So far I have this script:
It can replace all AAA of all files in all subfolders with BBB, but I did not find a way to replace it with the path.
I've been dabbling in IDL lately, and it seems useful enough, but occasionally I come across a problem like this: I'm trying to call an IDL procedure from within an IDL script which is called from a .csh script. (Don't ask, trust me, you don't want to know.) The IDL procedure may or may not be in the same directory as the .csh, so I'm calling it by it's full path: /home/ic/rad_sim However, all IDL will do is give me a syntax error and tell me ic is an undefined variable. Putting ic in double quotes makes the undefined variable error go away, but it still reports a syntax error.
It is little weird now that cron job is not working as i have set. I have set weekly job to send email but i am receiving multiple emails daily. Below is my code; # sends email every monday at 4:00 am 00 04 * * 1 /usr/bin/ruby /home/mbm/www/current/script/runner /home/mbm/www/current/app/models/add_to_delayed_job.rb -e production
00 -> Minutes 04 -> Hours (0-24) 1 -> Days / 0-6 / Sun - Sat
Sending email is fine but the time is not working so far as set.
The site that used to host the language spec file for .erb/.rhtml for ruby/rails syntax highlighting is no more.If someone could attach the file for gtksourceview-2.It's located in /usr/share/gtksourceview-2.0/ language-specs/ and probably called rhtml.lang
I'm the server guy which is why I don't know this, but were staging a new webserver and we use some custom perl scripts and as were moving the site over for testing, apache is blowing a perl error;Can't locate web.pm in @INC (@INC contains: /etc/perl /usr/local/lib/perl/5.10.0 /usr/local/share/perl/5.10.0 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.10 /usr/share/perl/5.10 /usr/local/lib/site_perl .) at /home/mcp/htdocs/cgi-bin/newgraph.gif line 11.,Now I can copy that file local, but there are a bunch of things, so the question is how do you globally add a folder to the perl search path
I have made the installation of Qt4 in my Fedora/MacBookPro. It also got a first compiling and running a simple program. The point is that for the compiler to run I need to point out every time where the bin is located, as that:
$ /home/threader/kinetic/bin/qmake -project
I have tried the following, but it still doesn't work:
# script #-----------------------------------------------------------# # /etc/bashrc or /home/threader/.bash_profile # config to Qt compiler
I'm using bash scripting to find any file that matches a path governed by the following regular expression:
"(monthly|nightly).[0-9]+/home/(user1|user2)/.mailbox/" to match files like: monthly.9/home/user1/.mailbox/l23131564 nightly.15/home/user2/.mailbox/cur/6546213
I want to share file locations with pc users (i'm a mac user). problem is: mac uses fslash, while pc files are indicated with baskslashes. I'm looking for a automation/plugin/shortcut/... to change them quick. I use paths a lot and share them with pc users, so manually it's to time consuming.
Is there a way to get the full path of a file in C? I have a method that accepts a file name as an argument and is supposed to read the content of the file. The file name might include "../" so this might lead to accessing files outside of the current directory. I tried to use fstat but I could not figure out how to get the full path.
I'm fighting my way through JAVA. But have hit another wall. Basically I need to to set paths in java so it can set/read files/director for Linux,Mac and windows.
The tutorials I'm using says to do this through the FileSystems class eg
Code:
However this reports it is missing, so a look on line says I need the headers so I set them with
Code:
This gives the following error
This has me totally confused as the tutorial shows this and checking online shows this, do I need to link in libraries or something like that?
I am trying to install rails 3.0.1 on ubuntu 10.10. I am getting this error towards the end when i execute this command sudo gem install rails --version 3.0.1.
I'm trying to install ruby on rails on Ubuntu 9.10. I'm following the instructions on this site: http://castilho.biz/blog/2009/11/05/...-karmic-koala/
However, when I try to install Rails I get an error code...
It seems like gem can't access http://gems.rubyforge.org/gems/rake-0.8.7.gem for some reason, but when I try to go directly to that address I get the option to download it. Any ideas how to get around this problem?
I'm thinking if I can somehow tell gem to look for the file locally I can download it and install rails that way.
I am trying to execute executable files in bash without adding ./ I know there must be an alias to add in .bashrc, that must be something like alias PATH=$PATH:. But this seems not to be working.
i'm trying to run some code i had written a couple of weeks ago in windows :$, the program has to create and copy some files and when i try to run this code in monodevelop this error:Unhandled Exception: System.UnauthorizedAccessException:Access to the path '/tmp' is denied.i've tried to change the path where i know i have read/write permissions but it doesn't seem to work, the code was originally written to create a file in the Temp folder in windows.
I'm trying to pass a path as a string to an array, but its evaluating it as a command instead. I want to take the literal string "/mnt/accounts/user/temp/*.jpg" and assign it to an array{1}, but when i echo the array variable, it displays it as
pic1.jpg pic2.jpg pic3.jpg
[code]....
I just want it to be the actual text "/mnt/accounts/user/temp/*.jpg" which i will be combining with other text to create a longer path elsewhere in the code.
We have a custom app that runs on boot on some older hardware running DSL linux, and their startup manager was quite simple. We purchased some newer Asus eeebox's which run xandros and things are quite stable and run nice with 1 exception.The application only runs from the root (/) location. This box auto logs in as 'user' and there is a /home/user/.kde/Autostart folder where you can stick scripts to run at boot. So I have a start.sh script, and with little bash programming tried things such as; sudo cd / sudo /startapp.pl
but the errors start spewing with the basic;can't find data/xyz as it's looking in the local.I thought there was a basic cwd (change working directory) but everything I try just forces the run from that location.Any ideas or suggestions are appreciated, but things like can you change the code, etc. can't be done, so it must be a programming thing. The only other thought I had but not sure, can you do a cronjob with @boot or something, that when the box starts, it can run this job as root and fire off?
I am programming in bash and really stuck finding directory names. I have a script to find all the .php files on my / partition which will return the whole path. Is there a way to print directory hierarchy with all those values leaving out the forward slashes.
For gcc, it seems that there are multiple include paths like /usr/include and /usr/src/linux/include. How do I check the current include path for gcc via command line? How do I edit it?
im trying to write a makefile which contains :two cpp files and two header files. now i've put cppfiles in a folder called source whose path is: /root/workspace/source and header files in a folder called header whose path is:
/root/workspace/makedemo/header
my makefile is in the path:/root/workspace/makedemo my makefile was like this:
Code:
HEADERS = $(shell /root/workspace/makedemo/header ls *.h) SOURCES = $(shell /root/workspace/source ls *.cpp) COMPILERFLAGS = -W -Wall DEBUGFLAGS = -g
[code].....
im sure that i've given the correct path but it is showing errors like this:
[root@localhost makedemo]# make /bin/sh: /root/workspace/source: is a directory /bin/sh: /root/workspace/source: is a directory g++ -W -Wall -I. -o output g++: no input files make: *** [output] Error 1
