MySQL Syntax error: unexpected keyword_do_block - mysql

Question

I am very new to Ruby and trying to complete a tutorial that I can't get to work properly. I am attempting to run rake db:migrate on my root folder and is giving me 3 separate error messages:
>rake db:migrate
rake aborted!
SyntaxError:
C:/Users/Bill/Sites/simple_cms/db/migrate/20170922050429_create_use
rs.rb:4: syntax error, unexpected keyword_do_block
create_table :users, do |t|
^
C:/Users/Bill/Sites/simple_cms/db/migrate/20170922050429_create_users.rb:5:
syntax error, unexpected tSTRING_BEG, expecting keyword_end
t.column "first_name", :string, :limit => 25
^
C:/Users/Bill/Sites/simple_cms/db/migrate/20170922050429_create_users.rb:5:
syntax error, unexpected ',', expecting keyword_end
t.column "first_name", :string, :limit => 25
^
Tasks: TOP => db:migrate
(See full trace by running task with --trace)
The Ruby code from my create_users.rb file is:
class CreateUsers < ActiveRecord::Migration[5.1]
def change
create_table :users, do |t|
t.column "first_name", :string, :limit => 25
t.string "last_name", :limit => 50
t.string "email", :default => "", :null => false
t.string "password", :limit => 40
t.timestamps
end
end
I am not sure what I am doing wrong here. Any insight would be appreciated!

Answer 1

in addition to first answer. Why don't you use rails generators?
Write migrations can be usefull when you have to modify something. Faster and cleaner way is using rails generators:
Example:
rails g model User first_name:string last_name:string
If attributes are string you can just
rails g model User first_name last_name
It will generate class User in /app/models/user.rb and migration for database.
Also you have Scaffold, and others generators.
More info: Command Line Rails
Tip: Check for Devise Gem, it will generate entire structure for User Model.

Answer 2

In your code:
def change
create_table :users, do |t|
t.column "first_name", :string, :limit => 25
t.string "last_name", :limit => 50
t.string "email", :default => "", :null => false
t.string "password", :limit => 40
t.timestamps
end
end
You have:
create_table :users, do |t|
which should be:
create_table :users do |t|
There should not be any comma after that unless you have more than one arguments there.
Update:
And also you class has no end which will not close the class definition and throw exception.
On a side note:
You have this line:
t.column "first_name", :string, :limit => 25
which can be written as:
t.string "first_name", :limit => 25
Hope this helps.
