First question:
Can be defined at the time that I'm generating the scaffold the size
of
a string?
For example name:string (50)?
Second question:
I wonder how to proceed correctly to include new
fields starting at a CRUD generated by scaffold.
Example:
First step (I use):
script/generate scaffold User name:string login:string
Second step (I add the field "password: string" in the User CRUD,
This field is a password varchar of 50 characters):
Problem --->>> I do not do this modification to add a new
field.
If you have any tutorial to make available, or, please specify
step-by-step how to proceed.
You can’t specify the size of the field while you are writing the scaffold command in the command prompt.
But, there’s a way you can do that.
Scaffolding makes a migration file for you, which actually makes the table for your model. You will find your migration file in /db/migrate folder in your application directory. Open your migration and add ,:limit => number after your column name.
Try it out…It worked for me.
regarding your second question, could you be a little more clear about adding on a password field.
class CreateUsuarios < ActiveRecord::Migration
def self.up
create_table :usuarios do |t|
t.string :nome
t.string :login, :limit => 20
e.g t.integer :age , :limit => 2 //Here you set the age to be a short.ie.it now occupies only 2 byte rather than actual 4 bytes of integer
t.timestamps
end
end
This way you can set limits on the size of your columns. Regarding your second question, I am still unable to get what you want to do.
