Hi everyone,
I am attempting to connect an already existing mysql database with
Rails. For This I can't use the traditional "generate scaffold" and
"rake db:migrate" because (I think), I'll loose the data already
existing in that database table. So what I did was, I generated a
scaffold for my table, and instead of running db:migrate, I added a
set_table_name to my model.
Of course, I get a bunch of errors whenever I do things like
Product.all, because I think my model's properties are not properly
mapped to the database table columns. So I began poking around my rails
app rolder and found a file named schema.rb in the "db" folder inside my
app, with content like this:
create_table "users", :force => true do |t|
t.text "username"
t.text "password"
t.text "email"
t.text "real_name"
t.datetime "created_at"
t.datetime "updated_at"
end
There were also some comments about not editing this file manually, but
to use migrations instead.
So the questions are: How does Rails know which properties from the
model to match to the database fields? What is the purpose of
db\schema.rb? And how, then, would you reccomend that I connect this
table to my Rails app?
