Is there an equivalent of ActiveRecord's find(:include) in Elixir/SQLAlchemy?
I had been using ActiveRecord previously and it allowed to load all associations of an object using an optional :include argument to its dynamic finders. I have recentl开发者_JS百科y started using Elixir for a python project and am unable to find any documentation that'd suggest if it's possible to do the same.
Using plain SQLAlchemy (without Elixir): http://www.sqlalchemy.org/docs/orm/loading.html
I assume you can configure the loading strategies using Elixir as well, but I have never used it.
EDIT 1:
According to the Elixir documentation, options to the relationship constructs (for instance ManyToOne
) can include options that are passed directly to the SQLAlchemy relation
(relationship
if version >= 0.6) function. That means you can specify the lazy
option to control the loading for associated objects.
I assume that Elixir's query
method is a thin wrapper around SQLAlchemy's. In that case, you can also control lazy/eager loading for individual queries. See the documentation.
EDIT 2:
Have you considered using sqlalchemy.ext.declarative
instead of Elixir?
