I have a question about using link_to in template and in console
Say I do rails new blah, I make a model called User, I make a table users,
each user has a field called 'name'. I have resources :users, in
config/routes.rb And I add some users.
in template, I can do
<% @z=User.find_by(name

You understand that there's a controller I'm trying to reference but that's
about it.

Is it possible to reference welcome#index, in the routes file?
e.g. suppose you create a rails program,
so then you do ralsi server you get the welcome page come up.
but the routes file is blank. The welcome controller hasn't been
referenced explicitly.
i'd like to reference it explicitly.

why is id off by one or defined different in edit vs in update? I will
explain what I mean
I have a controller called Bottles and a model Bottle
My config\routes.rb file has the line- resources :bottles
I have this controller
class BottlesController < ApplicationController
def index
end
What, if any, partial reload, does creating a table from the rails console
do?
I'll explain what I mean
C:\rubytest\proj>rails new abc1
..
C:\rubytest\proj>cd abc1
C:\rubytest\proj\abc1>cd app\models
C:\rubytest\proj\abc1\app\models>notepad blah.rb

If I go to rails console
I can't get a create_table statement onto one line
irb(main):019:0> ActiveRecord::Migration.create_table :wers { |t| t.string
:name }
SyntaxError: (irb):19: syntax error, unexpected '{', expecting end-of-input
Migration.create_table :wers { |t| t.string :name }

No, ERB is not IRB
Hi
Is there a command line ERB?
I've heard of one but if I look for an ERB executable I can't see one
I am in windows, I don't know if there is one in linux but not in windows?
if perhaps the issue is different distros of ruby , I don't know which
distro I have / how to find out.
Thanks

It works fine as far as this
C:\blah>rails new test1
C:\blah\test1>rails server
I edit application_controller.rb
I add a function called hello
def hello
render plain: "aasdf"
end
I edit the routes.rb file
I add this line into the existing procedure within routes.rb root
'application#h
I've got the program in chapter 2.
is there anything i can type in the console to reset the id? I can do e.g.
User.delete_all and delete all users, but if a new user is then created it
doesn't have an id of 1 'cos the id doesn't reset.
this User.reset_primary_key doesn't work either.
