Instance Method Details

#params ⇒ Object

Provides access to the params hash that will be available within the view.

params[:foo] = 'bar'

def params
  controller.params
end

#render ⇒ Object #render({partial: path_to_file}) ⇒ Object #render({partial: path_to_file}, {... locals ...}) ⇒ Object #render({partial: path_to_file}, {... locals ...}) ⇒ Object

Delegates to ActionView::Base#render, so see documentation on that for more info.

The only addition is that you can call render with no arguments, and RSpec will pass the top level description to render:

describe "widgets/new.html.erb" do
  it "shows all the widgets" do
    render # => view.render(file: "widgets/new.html.erb")
    # ...
  end
end

def render(options = {}, local_assigns = {}, &block)
  options = _default_render_options if Hash === options && options.empty?
  super(options, local_assigns, &block)
end

#response ⇒ Object

Deprecated.

Use rendered instead.

def response
  # `assert_template` expects `response` to implement a #body method
  # like an `ActionDispatch::Response` does to force the view to
  # render. For backwards compatibility, we use #response as an alias
  # for #rendered, but it needs to implement #body to avoid
  # `assert_template` raising a `NoMethodError`.
  unless rendered.respond_to?(:body)
    def rendered.body
      self
    end
  end
  rendered
end

#stub_template(hash) ⇒ Object

Simulates the presence of a template on the file system by adding a Rails' FixtureResolver to the front of the view_paths list. Designed to help isolate view examples from partials rendered by the view template that is the subject of the example.

stub_template("widgets/_widget.html.erb" => "This content.")

def stub_template(hash)
  view.view_paths.unshift(StubResolverCache.resolver_for(hash))
end

#template ⇒ Object

Use view instead.

def template
  RSpec.deprecate("template", replacement: "view")
  view
end

#view ⇒ Object

The instance of ActionView::Base that is used to render the template. Use this to stub methods before calling render.

describe "widgets/new.html.erb" do
  it "shows all the widgets" do
    view.stub(:foo) { "foo" }
    render
    # ...
  end
