rails 3: display link as button?

On some non-form pages, I have a few links that would look better as a button than a hyperlink...

I thought button_to instead of link_to would work, 开发者_开发知识库but buton_to seems to always be treated as a post.

Is there an easy way to simply replace a (non-submit) link with a button?

All you have to do is add a :method => "get" to the end of your button_to to get it to be treated like a link

The button_to Way

Using a users_path

<%= button_to "BUTTON: link version", users_path, :method => "get" %>

The CSS Way

Or instead of actually inserting a form into your html (which is what button_to actually does) you could go with the cleaner (from a web design perspective) method and actually just style the link in a way to make it look like a button This has several benefits

Keeps forms out of your HTML, when they really shouldn't be there

Keeps your erb clean and normal, no surprises

Awesomely flexible, you can make them look the way you want

Here is a great article on how to do it and here is a little snippet of that code, really just depends on playing around with the border, padding and background image

a.button {
  background: transparent url('bg_button_a.gif') no-repeat scroll top right;
  color: #444;
  display: block;
  float: left;
  font: normal 12px arial, sans-serif;
  height: 24px;
  margin-right: 6px;
  padding-right: 18px; /* sliding doors padding */
  text-decoration: none;
}

The code comes from the link above. Whichever method you choose should work fine, enjoy!

I think all you want here is the just view. and if that is the case then you can just add a class to the class object in link

<%= link_to 'Add Class', new_subject_path, class: "btn btn-primary"%>

I recently had to do this because my form was acting differently for link_to than it was with button_to and I needed the functionality the link provided. The best solution I found does not use CSS at all but instead calls .html_safe to escape the html in the ruby code and properly display the link as a button. What you want to do is this:

<%= link_to "<button>This is a button</button>".html_safe, some_path, :id => "button_id", :class => "button_class" %>

If all you want to do is make a link look like a button.

Changing link_to to button_to is all I needed to do.
