If you're looking for a slick CLI interface check out retscli, which is an awesome tool for exploring metadata or learning about RETS.
gem install rets
# or add it to your Gemfile if using Bundler then run bundle install
gem 'rets'
We need work in this area! There are currently a few guideline examples in the example folder on connecting, fetching a property's data, and fetching a property's photos.
Metadata, which is loaded when a client is first started, can be slow to fetch. To avoid the cost of fetching metadata every time the client is started, metadata can be cached.
To cache metadata, pass the :metadata_cache option to the client when you start it. The library comes with a predefined metadata cache that persists the metadata to a file. It is created with the path to which the cached metadata should be written:
metadata_cache = Rets::Metadata::FileCache.new("/tmp/metadata")
When you create the RETS client, pass it the metadata cache:
client = Rets::Client.new(
...
metadata_cache: metadata_cache
)
If you want to persist to something other than a file, create your own metadata cache object and pass it in. It should have the same interface as the built-in Metadata::FileCache class:
class MyMetadataCache
# Save the metadata. Should yield an IO-like object to a block;
# that block will serialize the metadata to that object.
def save(&block)
end
# Load the metadata. Should yield an IO-like object to a block;
# that block will deserialize the metadata from that object and
# return the metadata. Returns the metadata, or nil if it could
# not be loaded.
def load(&block)
end
end
By default, the metadata is serialized using Marshal. You may select JSON or YAML instead, or define your own serialization mechanism, using the :metadata_serializer option when you create the Rets::Client:
client = Rets::Client.new(
...
metadata_serializer: Rets::Metadata::JsonSerializer.new
)
The built-in serializers are:
- Rets::Metadata::JsonSerializer
- Rets::Metadata::MarshalSerializer
- Rets::Metadata::YamlSerializer
To define your own serializer, create an object with this interface:
class MySerializer
# Serialize to a file. The library reserves the right to change
# the type or contents of o, so don't depend on it being
# anything in particular.
def save(file, o)
end
# Deserialize from a file. If the metadata cannot be
# deserialized, return nil.
def load(file)
end
end
