ruby-on-rails - 更改模型计数的更具可读性的请求规范

我有以下通过的 rspec 请求规范示例

it "increases count by 1" do
  attributes = attributes_for(:district)
  expect { post admin_districts_path, params: { district: attributes} }.to change { District.count }.by(1)
end

expect 行有点忙，所以我想把它拆开。以下导致错误

it "increases count by 1" do
  attributes = attributes_for(:district)
  block = { post admin_districts_path, params: { district: attributes} }
  expect(block).to change { District.count }.by(1)
end

有错误

syntax error, unexpected '}', expecting keyword_end

为什么会发生此错误？有没有更简洁的方法来编写这个规范示例？

最佳答案

此外，您可以创建一个 lambda:

block = -> { post admin_districts_path, params: { district: attributes} }
expect(block).to change { District.count }.by(1)
