    take in Rails:Rails has so many methods that provide the facility to fetching the records from database, so that you don't need to write raw sql. One of them is take.
    By using take we can fetch a record (or N number of records if specified as a parameter) from a table. take doesn't take care of order. The order depends upon the database implementation.

    Example:

    blog = Blog.take
    # => #<Blog id: 1, title: "Active Records in Rails">
    #Sql equivalent is
    SELECT * FROM blogs LIMIT 1
    


    If we want to retrieve n records we can pass it as an argument

    blog = Blog.take(2)
    # => #<Blog id: 1, title: "Active Records in Rails">
    # => #<Blog id: 4, title: "Active Records Validation">
    #Sql equivalent is
    SELECT * FROM blogs LIMIT 2
    


    It can be used with where also:

    blog = Blog.where(title:"Active Records in Rails").take
    

    One similar method is take!. But it returns "ActiveRecord::RecordNotFound" if no record is found.
