Ruby on Rails：使用 post 方法链接，但参数位于 URL 中
我正在使用
link_to 'My link', path(:arg1 => session[:arg1], :arg2 => session[:arg2],:arg3 => anyobject.id), :method => :post
，但生成的 HTML 链接包含 (arg1,arg2,arg3) 作为 URL 查询参数。
如何去除它们？我错过了文档中的某些内容吗？
I'm using
link_to 'My link', path(:arg1 => session[:arg1], :arg2 => session[:arg2],:arg3 => anyobject.id), :method => :post
but the HTML link being generated includes (arg1,arg2,arg3) as URL query parameters.
How can remove them? Did I miss something in the documentation?

link_to始终会将参数放入查询字符串中，因为它正在创建 get 样式的 HTML 链接 - 即使您将:method =>; :post只是附加一个额外的（“特殊”）参数_method。我认为你真正想要的是一个
button_to链接 - 它将使其成为一种表单帖子。它的工作原理相同，但它显示为button_to（例如，button_to 'My link', path(:params => :go_here)。缺点是它看起来像一个按钮。但是您可以给它一个 CSS 类（例如“unbutton”），然后更改该 CSS 类的样式，使其看起来不像一个按钮。或者，如果您真正想要的实际上是没有 按钮。
params完全传递给控制器...然后在创建链接时不要包含它们（例如，link_to“My link”路径- 不需要:post如果您不想发布任何params）。最后，如果您想要的是
params成为 的一部分。 URL（例如，stuff/[param_1]/more_stuff/[param_2]等），那么您需要更新您的路由以将这些参数作为选项包含在内。 rdoc 了解如何执行此操作。A
link_towill always put the arguments into the query string as it is creating a get-style HTML link - even if you put:method => :postthat just appends an extra ("special") argument_method.What I think you really want is a
button_tolink - which will make it into a sort of form-post. It works the same, but it saysbutton_toinstead (for example,button_to 'My link', path(:params => :go_here). The downside is that it will look like a button. But you can give it a CSS class (eg "unbutton") and then change the styling on that CSS class to make it not look like a button.Alternatively, if what you really want is actually to have no
paramspassed to the controller at all... then just don't include them when making your link (for example,link_to "My link" path- there's no need for:postif you don't want to post anyparams).Finally, if what you want is for the
paramsto become a part of the URL (for example,stuff/[param_1]/more_stuff/[param_2], etc.) then you need to update your routes to include these parameters as options. Have a look at the routing section of the rdoc for how to do that.您可以使用下面的代码，其中 rails.js 需要 data-method 在 Ajax 中切换到 post 模式。
<%= link_to ''.html_safe, { 控制器: :lots, id: @lot.containername , 操作: "print_#{print_template}", 远程: true }, {'data-method' => :post} %>You can use below code, which rails.js need data-method to switch to post mode in Ajax.
<%= link_to '<button id="print" type="submit" class="btn">Print</button>'.html_safe, { controller: :lots, id: @lot.containername, action: "print_#{print_template}", remote: true }, {'data-method' => :post} %>
