Good afternoon.

I have two questions:

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.

Best Regards …

Regarding your first question,  
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.

</div>

Regarding the first question, you can put an example?

Currently in my db / migrate is thus:

class CreateUsuarios \< ActiveRecord::Migration  
def self.up  
create\_table :usuarios do |t|  
t.string :nome  
t.string :login

```
  t.timestamps
end

```

end

def self.down  
drop\_table :usuarios  
end  
end

How to get the code?

Referring to my second question I could find out how.

</div>

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.
