Description
This may be a duplicate/related to MONGOID-4683, but I think it is different because this depends on how the field is accessed. I have found this in hash fields (but I'm sure it could be reproduce in other fields too).
Here is an example model:
class SomeHashModel |
include Mongoid::Document
|
field :some_hash, type: Hash |
end |
If I reference the field using `[:some_hash]` I get the following results.
|
|
something = SomeHashModel.create(some_hash:{key1: 'value1'}) |
something[:some_hash].merge!(key2: 'value2') |
# or something[:some_hash][:key2] = 'value2'
|
something.save!
|
something.some_hash # => {key1: 'value1', key2: 'value2'} |
something.reload
|
something.some_hash # => {key1: 'value1'} |
|
If I reference the field using `.some_hash` sometime before I change the object I get the following results.
something = SomeHashModel.create(some_hash: {key1: 'value1'}) |
something.some_hash
|
something[:some_hash].merge!(key2: 'value2') |
# or something[:some_hash][:key2] = 'value2'
|
something.save!
|
something.some_hash # => {key1: 'value1', key2: 'value2'} |
something.reload
|
something.some_hash # => {key1: 'value1', key2: 'value2'} |
|
I have also noticed that if it is a string, it doesn't seem to depend on how I reference the field. Here is an example:
class SomeStringModel |
include Mongoid::Document
|
|
|
field :some_string, type: String |
end |
|
|
something_created = SomeStringModel.create(some_string: 'value1') |
# This line below is only needed if you have '# frozen_string_literal: true'
|
something = SomeStringModel.find(something_created.id)
|
# or something.some_hash
|
something[:some_string].prepend('something_super_cool_') |
something.save!
|
something.some_string # => 'something_super_cool_value1' |
something.reload
|
something.some_string # => 'value1' |
