Ruby-on-rails 如何使用 Capybara 获取带有查询字符串的当前路径

How to get current path with query string using Capybara

提问by kriysna

The page url is something like /people?search=namewhile I used current_pathmethod of capybara it returned /peopleonly.

页面 url 就像/people?search=name我使用current_path水豚的方法一样，它只返回/people。

current_path.should == people_path(:search => 'name')

But it fails saying

但它没有说

expected: "/people?search=name"
got: "/people"

How we can make it pass? Is there is any way to do this?

我们怎样才能让它通过？有没有办法做到这一点？

I've updated this answer to reflect modern conventions in capybara. I think this is ideal since this is the accepted answer, and what many people are being referred to when looking for a solution. With that said, the correct way to check the current path is to use the has_current_path?matcher provided by Capybara, as documented here: Click Here

我已经更新了这个答案以反映水豚的现代惯例。我认为这是理想的，因为这是公认的答案，也是许多人在寻找解决方案时所参考的答案。话虽如此，检查当前路径的正确方法是使用has_current_path?Capybara 提供的匹配器，如此处所述：单击此处

Example usage:

用法示例：

expect(page).to have_current_path(people_path(search: 'name'))

As you can see in the documentation, other options are available. If the current page is /people?search=namebut you only care that it's on the /peoplepage regardless of the param, you can send the only_pathoption:

正如您在文档中看到的那样，还有其他选项可用。如果当前页面是/people?search=name但您只关心它在/people页面上而不管参数如何，您可以发送only_path选项：

expect(page).to have_current_path(people_path, only_path: true)

Additionally, if you want to compare the entire URL:

此外，如果要比较整个 URL：

expect(page).to have_current_path(people_url, url: true)

I replaced the _path method with _url to achieve comparing the full urls with parameters.

我用 _url 替换了 _path 方法，以实现将完整 url 与参数进行比较。

current_url.should == people_url(:search => 'name')

Just updating this question for modern times. The current best practice for checking current_paths when using Capybara 2.5+ is to use the current_path matcher, which will use Capybaras waiting behavior to check the path. If wanting to check against the request_uri (path and query string)

只是为现代更新这个问题。当前在使用 Capybara 2.5+ 时检查 current_paths 的最佳实践是使用 current_path 匹配器，它将使用 Capybara 等待行为来检查路径。如果要检查 request_uri（路径和查询字符串）

expect(page).to have_current_path(people_path(:search => 'name'))  

If only wanting the path part (ignoring the query string)

如果只想要路径部分（忽略查询字符串）

expect(page).to have_current_path(people_path, only_path: true) # Capybara < 2.16
expect(page).to have_current_path(people_path, ignore_query: true) # Capybara >= 2.16

If wanting to match the full url

如果想匹配完整的 url

expect(page).to have_current_path(people_url, url: true) # Capybara < 2.16
expect(page).to have_current_path(people_url) # Capybara >= 2.16

the matcher will take a string which is compared with == or a regex to match against

匹配器将采用与 == 或正则表达式进行比较的字符串进行匹配

expect(page).to have_current_path(/search=name/)

I know an answer has been selected, but I just wanted to give an alternative solution. So:

我知道已经选择了一个答案，但我只是想提供一个替代解决方案。所以：

To get the path and querystring, like request.fullpathin Rails, you can do:

要获取路径和查询字符串，就像request.fullpath在 Rails 中一样，您可以执行以下操作：

URI.parse(current_url).request_uri.should == people_path(:search => 'name')

You can also do a helper method in your test class (like ActionDispatch::IntegrationTest) like this (which is what I did):

你也可以在你的测试类中做一个辅助方法（比如ActionDispatch::IntegrationTest），就像这样（我就是这样做的）：

def current_fullpath
  URI.parse(current_url).request_uri
end

Hope this helps.

希望这可以帮助。
