Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(name, *args, &block) ⇒ Object (private)

Note:

Due to the way this works, be careful not to use this syntactic sugar with existing ActiveRecord::Base methods (see last example).

Equivalent to calling #attribute with the missing method’s name if the table has a column with that name.

Delegates to superclass implementation otherwise, eventually raising NoMethodError.

Examples:

# Suppose the "users" table has an "email" column, then these are equivalent:
User.email
User.attribute(:email)

# Here is the previous example (from `attribute`) rewritten:
User.where(User.score > 1000)
# => SELECT "users".* FROM "users" WHERE ("users"."score" > 1000)

# Don't use it with existing `ActiveRecord::Base` methods, i.e. `name`:
User.name # => "User"
# In these cases you'll have to use `attribute` explicitely
User.attribute(:name)

Raises:

• (NoMethodError) —

  if the table has no corresponding column
