I honestly don\u2019t know if there are still any dinosaurs like me using TextMate<\/strong>
\nin 2025. But if you\u2019re a die-hard TextMate fan like I am, then I\u2019ve got some
\nexciting news for you. Have you ever heard of rmate<\/code>?<\/p>\n\n

rmate<\/code> is actually a Ruby gem. What does it do? It lets you open a file from
\na remote server (via SSH) directly in your local TextMate editor\u2014just as if
\nyou had run mate \/path\/to\/file<\/code> on your own machine.<\/p>\n\n

In TextMate, under Settings > Terminal<\/strong>, there\u2019s an option called Accept rmate connections<\/strong>\u2014make sure that\u2019s checked first. <\/p>\n\n

\"TextMate<\/a><\/p>\n\n

Next, connect to your VPS via SSH and install Ruby, followed by rmate<\/code>, using the commands below. Let\u2019s assume you\u2019re using Ubuntu<\/strong> as your VPS operating system:
\n<\/p>\n\n

\n
sudo <\/span>apt install <\/span>ruby -y<\/span>\n<\/code><\/pre>\n\n<\/div>\n\n\n\n
Now, find the location for user installation directory for
\nruby gems:
\n<\/p>\n\n
\n
gem environment | grep<\/span> \"USER INSTALLATION DIRECTORY\"<\/span> | awk<\/span> -F<\/span>': '<\/span> '{print $2}'<\/span>\n# something like:<\/span>\n# \/home\/ubuntu\/.local\/share\/gem\/ruby\/3.2.0\/bin<\/span>\n<\/code><\/pre>\n\n<\/div>\n\n\n\n
Now, edit your ~\/.bashrc<\/code> and add this path to your PATH<\/code> environment
\nvariable:
\n<\/p>\n\n
\n
# set PATH if local ruby gems bin exists<\/span>\nPATH<\/span>=<\/span>\"<\/span>${<\/span>PATH<\/span>}<\/span>:<\/span>${<\/span>HOME<\/span>}<\/span>\/.local\/share\/gem\/ruby\/3.2.0\/bin\"<\/span>\n<\/code><\/pre>\n\n<\/div>\n\n\n\n
Save and exit from nano<\/code>. Now install rmate<\/code>:
\n<\/p>\n\n
\n
gem install<\/span> --user-install<\/span> rmate\n<\/code><\/pre>\n\n<\/div>\n\n\n\n
Now, restart your shell, logout\/login works fine. Now run:
\n<\/p>\n\n
\n
sudo <\/span>visudo\n<\/code><\/pre>\n\n<\/div>\n\n\n\n
Edit your sudo configuration, Two changes, add env_keep<\/code> and append
\n\/home\/ubuntu\/.local\/share\/gem\/ruby\/3.2.0\/bin<\/code> to secure_path<\/code> under the line
\nof Defaults env_reset<\/code>:<\/p>\n
\n
Defaults        env_reset\nDefaults        env_keep +=\"RMATE_HOST\"\nDefaults        secure_path=\"\/usr\/local\/sbin:\/usr\/local\/bin:\/usr\/sbin:\/usr\/bin:\/sbin:\/bin:\/snap\/bin:\/home\/ubuntu\/.local\/share\/gem\/ruby\/3.2.0\/bin\"\n<\/code><\/pre>\n\n<\/div>\n
Now, restart your shell, logout\/login works fine. Now open (as an example):
\n<\/p>\n\n
\n
sudo<\/span> -E<\/span> rmate \/etc\/nginx\/nginx.conf\n<\/code><\/pre>\n\n<\/div>\n\n\n\n
sudo -E<\/code> does the trick! -E<\/code> keeps environment variables which are defined
\nin env_keep<\/code>.<\/p>\n\n
Thats all! Keep the TextMate<\/strong> spirit alive! (macOS only<\/em>)<\/p>\n\n","category":["textmate","macos","vps","ssh"]},{"title":"Django Model Best Practices","pubDate":"Thu, 26 Aug 2021 11:13:31 +0000","link":"https:\/\/dev.to\/vigo\/django-model-best-practices-3e8e","guid":"https:\/\/dev.to\/vigo\/django-model-best-practices-3e8e","description":"
I've been writing Django apps since 2008. Here are some Django Model tips that I've collected, applied over the years.<\/p>\n\n
\n  \n  \n  Model Writing Rules\n<\/h2>\n\n
Before you do anything, please visit and read this doc<\/a>. Django documentation is your friend!<\/p>\n\n
Doc tells that, there is a rule\/order in the Model class:<\/p>\n\n
    \n
  1. All field declarations <\/li>\n
  2. Custom manager attributes<\/li>\n
  3. class Meta<\/code><\/li>\n
  4. def __str__()<\/code><\/li>\n
  5. def save()<\/code><\/li>\n
  6. def get_absolute_url()<\/code><\/li>\n
  7. You custom methods, properties etc...<\/li>\n<\/ol>\n\n
    Here is an example:

    \n  \n  \n  Correct Model Name\n<\/h2>\n\n
    Model stands for a single element in the database. Model name should be singular. In some cases, Model name can be plural if you are building intermediate relations table since this is a different situation. <\/p>\n\n
