Rails:更改语言环境并保留页面参数
我有一个导航栏，其中包含指向不同语言的链接:
I have a navbar with links to different languages:
<%= link_to t('header.english'), locale: "en" %>
问题是，当用户尝试在包含url中其他参数的页面上切换语言时.此时更改语言环境将重新加载页面并剥离所有其他参数.
The problem is when user tries to switch language on a page which contains additional parameters in the url. Changing locale at this point reloads the page and strips all the additional parameters.
那么，如何将所有参数从当前页面传递到语言环境切换链接?
So, how do I pass all the parameters from the current page to the locale switch link?
例如，当
/page/new?param1=1¶m2=2
已打开，并且用户切换了语言环境，
is open, and user switches the locale,
/page/new?locale=en
已打开，并且两个附加参数也从网址中剥离.
is opened, and both additional parameters are stripped away from the url.
这不是执行此操作的好方法.请参见下面的评论.
问题是创建语言环境切换器链接时您没有将当前参数传递给link_to.
The problem is that you are not passing the current params to link_to when you create the locale switcher link.
将您的导航栏链接更改为:
Change your navbar link to:
<%= link_to t('header.english'), params.merge(locale: "en") %>
