Constructor Details

#initialize(attributes = {}, &block) ⇒ Base

New objects can be instantiated as either empty (pass no construction parameter) or pre-set with attributes.

Example:

# Instantiates a single new object
UserMock.new(first_name: 'Jamie')

.create(attributes = {}, &block) ⇒ Object Also known as: create!

Creates an object (or multiple objects) and saves it to memory.

The attributes parameter can be either a Hash or an Array of Hashes. These Hashes describe the attributes on the objects that are to be created.

Examples

# Create a single new object
User.create(first_name: 'Jamie')

# Create an Array of new objects
User.create([{ first_name: 'Jamie' }, { first_name: 'Jeremy' }])

# Create a single object and pass it into a block to set other attributes.
User.create(first_name: 'Jamie') do |u|
  u.is_admin = false
end

# Creating an Array of new objects using a block, where the block is executed for each object:
User.create([{ first_name: 'Jamie' }, { first_name: 'Jeremy' }]) do |u|
  u.is_admin = false
end

  end
end

.delete(id) ⇒ Object

Delete an object (or multiple objects) that has the given id.

This essentially finds the object (or multiple objects) with the given id and then calls delete on it.

Parameters

  • id - Can be either an Integer or an Array of Integers.

Examples

# Destroy a single object
TodoMock.delete(1)

# Destroy multiple objects
todos = [1,2,3]
TodoMock.delete(todos)

  end
end

Deletes the records matching conditions.

end

.destroy ⇒ Object

Delete an object (or multiple objects) that has the given id.

This essentially finds the object (or multiple objects) with the given id and then calls delete on it.

Parameters

  • id - Can be either an Integer or an Array of Integers.

Examples

# Destroy a single object
TodoMock.delete(1)

# Destroy multiple objects
todos = [1,2,3]
TodoMock.delete(todos)

#assign_attributes(new_attributes) {|_self| ... } ⇒ Object Also known as: attributes=

Allows you to set all the attributes by passing in a hash of attributes with keys matching the attribute names (which again matches the column names).

cat = Cat.new(name: "Gorby", status: "yawning")
cat.attributes # =>  { "name" => "Gorby", "status" => "yawning", "created_at" => nil, "updated_at" => nil}
cat.assign_attributes(status: "sleeping")
cat.attributes # =>  { "name" => "Gorby", "status" => "sleeping", "created_at" => nil, "updated_at" => nil }

Aliased to attributes=.

Yields:

  • (_self)

end

#attribute_names ⇒ Object

Returns an array of names for the attributes available on this object.

person = Person.new
person.attribute_names
# => ["id", "created_at", "updated_at", "name", "age"]

end

#attribute_present?(attribute) ⇒ Boolean

Returns true if the specified attribute has been set and is neither nil nor empty? (the latter only applies to objects that respond to empty?, most notably Strings). Otherwise, false. Note that it always returns true with boolean attributes.

person = Task.new(title: '', is_done: false)
person.attribute_present?(:title)   # => false
person.attribute_present?(:is_done) # => true
person.name = 'Francesco'
person.is_done = true
person.attribute_present?(:title)   # => true
person.attribute_present?(:is_done) # => true

Returns:

end

#freeze ⇒ Object

Will not allow attributes to be changed

Will freeze attributes forever. Querying for the record again will not unfreeze it because records exist in memory and are not initialized upon a query. This behaviour differs from ActiveRecord, beware of any side effect this may have when using this method.

#has_attribute?(attr_name) ⇒ Boolean

Returns true if the given attribute is in the attributes hash, otherwise false.

person.has_attribute?(:nothing) # => false
