Module: Graphiti::SpecHelpers::Matchers

Defined in:
lib/graphiti/spec_helpers/matchers.rb

Overview

Assertions against a resource's DSL. The schema specs cannot cover adapter-dependent options (primary key, foreign key, and so on) because the schema does not carry them; these read the resource config directly.

Defined Under Namespace

Classes: BaseMatcher, BelongsToMatcher, ExposeAttributeMatcher, FilterAttributeMatcher, HasManyMatcher, HasOneMatcher, RelationMatcher, ResourceDSLMatcher
