basically you need to transform the class name of the model into something pointing to the correct path. model_name = m.class.to_s.underscore And then use it to call the appropriate path methods link_to “edit”, send(“edit_#{model_name}_path”, m) As an aside, you don’t need to put the link_tos in #{} because that function simply returns a string.
I cannot understand how resolve() and relativize() method works? Path resolve(Path) resolves the given path against this path. Path relativize(Path) constructs a relative path of the given path against this path . These are reverse operations. Path resolve(Path other) In the general use case of resolve(), you want to return a new Path object where … Read more
A bit late to the party with a couple of single-line suggestions that don’t require writing a custom function nor the use of a loop and work on Linux: pathlib.Path.glob() takes interleaved symbols in brackets. For the case of “.txt” and “.xls” suffixes, one could write files = pathlib.Path(‘temp_dir’).glob(‘*.[tx][xl][ts]’) If you need to search for … Read more

If you want to do it from Go code, you may use the user.Current() function to get details about the current user, including its home folder which will be … Read more

The most idiomatic way would be to just use an existing crate, in this case shellexpand (github, crates.io) seems to do what you want: extern crate shellexpand; // 1.0.0 #[test] fn test_shellexpand() { let home = std::env::var(“HOME”).unwrap(); assert_eq!(shellexpand::tilde(“~/foo”), format!(“{}/foo”, home)); } Alternatively, you could try it with dirs (crates.io). Here is a sketch: extern crate … Read more
sys.executable contains full path of the currently running Python interpreter. import sys print(sys.executable) which is now documented here
Python adds the directory where the initial script resides as first item to sys.path: As initialized upon program startup, the first item of this list, path[0], is the directory containing the script that was used to invoke the Python interpreter. If the script directory is not available (e.g. if the interpreter is invoked interactively or … Read more
You can assign a named route to a static file by passing any non-empty string as :controller and the path to the file as the :action for the route: Application.routes.draw do root :controller => ‘static’, :action => “https://stackoverflow.com/” # or # root :controller => ‘static’, :action => ‘/public/index.html’ end # elsewhere redirect_to root_path # redirect … Read more
