ActiveRecord: List columns in table from console

Question

I know that you can ask ActiveRecord to list tables in console using:

ActiveRecord::Base.connection.tables

Is there a command that would li

Answer 1

complementing this useful information, for example using rails console o rails dbconsole:

Student is my Model, using rails console:

$ rails console
> Student.column_names
 => ["id", "name", "surname", "created_at", "updated_at"] 

> Student
 => Student(id: integer, name: string, surname: string, created_at: datetime, updated_at: datetime)

Other option using SQLite through Rails:

$ rails dbconsole

sqlite> .help

sqlite> .table
ar_internal_metadata  relatives             schools             
relationships         schema_migrations     students 

sqlite> .schema students
CREATE TABLE "students" ("id" integer PRIMARY KEY AUTOINCREMENT NOT NULL, "name" varchar, "surname" varchar, "created_at" datetime NOT NULL, "updated_at" datetime NOT NULL);

Finally for more information.

sqlite> .help

Hope this helps!
