11,515 PointsRails definitions clarification
Starting at 2:43 you state that "we'll call the get method to set up a get route". When you use the term method here, are you talking about, for example:
def name
puts "hello"
end
kind of method, or some other definition of method, such as the definition of the the GET method listed at https://robots.thoughtbot.com/back-to-basics-http-requests?
I went looking for rails documentation that listed what the get method syntax might be but I wasn't able to find a definition. It doesn't look like a "normal" method that you are passing a parameter due to the lack of parenthesis.
When you use the to: ... whatever that is...a key value pair maybe? Where would I find more information on the ...key/value pairs? I can send in routes (Or parameters or whatever?).
There is a lot here that I am being asked to take on faith that eventually I will get an explanation for, but as far as I can tell its never brought up again. This feels really sloppy and unfinished.

With regards to we'll call the get method to set up a get route"
, he is referring to what he then types in on line 3 (3:49)
get '/pages', to: 'pages#index'
which you can read as
get(
/pages, {to: 'pages#index'
})`
- First parameter is the name of the route (
/pages
) - Second parameter is the key value pair. At this stage the most relevant key to learn is
to:
, with the valuecontroller#action
It tells rails what function to call when the route is hit. For'pages#index
, it will go to the pages controller and call the index function.
Official rails documentation is a good start: https://guides.rubyonrails.org/routing.html
