Rails Overall Architecture Best Practices -


i'm interested see rails veterans on stack overflow have this.

basically, rails newb, , no "formal" background in programming, 1 of biggest challenges has proper architecture. how know right or better build app are?

i love see resources are.

i know basic ones - lot of these don't give me high level architecture overview want:

here's quick example:

say i'm building rails app has merchants , shoppers - each set of users has own authentication, different permissions, etc. proper build single app or multiple communicate through apis? there added benefit multi-app abstraction?

thanks!

this not easy question. complete answer largely depend on project.

if starter i'd recommend keep in 1 app, have enough "separation" using models wisely. it's hard immagine scenario complexity introduced inter-app communication beneficial.

in example should ask wether it's better use 1 single parent model merchants , shoppers or 2 separate models.

in former case can consider sti:

  • user (main class, defined class user < activerecord::base)
    • merchant (defined class merchant < user)
    • shopper (similarly class shopper < user)

google sti further details.

then in controllers/view can check permissions quickly, example:

if user.class == merchant   do_something else   do_something_else end

similarly 2 classes might authenticate different algorithms. might include "standard" authentication in base user class , specialize in subclasses, if required.

cheers,

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
