undefined method 'assign_to' after updating shoulda-matchers

Question

I updated 'shoulda-matchers' in the Gemfile in my rails project from version 1.4.2 to 2.0.0 and now when I run my rspec tests, it is giving me the following error

undefined method `assign_to' for #<RSpec::Core::ExampleGroup::Nested_4::Nested_1::Nested_4::Nested_1:0x007fc96eaaaf48>

Was this method removed in the new 2.0.0 release?

Answer 1

Yes, the following methods were deprecated in version 1.5.0 and removed in version 2.0.0 of shoulda-matchers.

• assign_to
• respond_with_content_type
• query_the_database
• validate_format_of
• have_sent_email
• permit (strong parameters matcher)
• delegate_method

The developers recommend testing the code in another way if you are currently using these methods.
