Adding a Twitter Bootstrap button icon to button_to in Rails - ruby-on-rails

Question

I am working through the Agile Web Development with Rails book but I have been using Twitter Bootstrap instead of the custom styling from the book. I am having trouble adding an icon through GLyphonics to the button_to method. My code looks like this:
<%= button_to <i class="icon-search icon-white">Add To Cart</i>,
line_items_path(product_id: product),
class: "btn btn-success" %>
I have tried quite a few variations but can't seem to get it to work correctly.

Answer 1

I'm not sure how the OP got this to work, but Rails button_to generates an <input type='submit' /> element, which does not allow for HTML in the value field.
See also: input type="submit" Vs button tag are they interchangeable?
The best alternative in this situation is to force link_to to PUT (or POST):
<%= link_to raw("<i class=\"icon-search icon-white\">Add To Cart</i>"),
line_items_path(product_id: product),
class: "btn btn-success",
method: :put %>

Answer 2

You can add the icon as a child element:
<%= button_to button_path, method: :delete do %>
<span class="glyphicon glyphicon-search"></span>
<% end %>

Answer 3

It looks like you have an issue with your quotes:
<%= button_to raw("<i class=\"icon-search icon-white\">Add To Cart</i>"),
line_items_path(product_id: product),
class: "btn btn-success" %>
Enclose the label of the button in double quotes, escape the double quotes in your i tag, and finally, wrap everything into a raw() call to ensure the HTML is properly displayed.
Alternatively you can use html_safe:
<%= button_to "<i class=\"icon-search icon-white\">Add To Cart</i>".html_safe,
line_items_path(product_id: product),
class: "btn btn-success" %>
good point from #jordanpg: you can't have HTML in the value of a button, so his solution is more appropriate and should get the approved status.
the html_safepart remains valid though.

Answer 4

Using raw() or #html_safe still did not work for me.
I am using a helper method to create a button_to flag content. Ended up using the following in my helper method (path is defined beforehand):
form_tag path, :method => :post do
button_tag do
content_tag :i, 'Flag as inappropriate', :class => 'icon-flag flag_content'
end
end

Answer 5

I used this one and it works fine for me :
<%= link_to(line_items_path(product_id: product),
method: :put,
class: 'btn btn-success') do %>
<%= content_tag('i', nil, class: 'icon-search icon-white') %> Add To Cart
<% end %>
Hope this helps

Answer 6

I am using this helper:
module ApplicationHelper
def glyph(*names)
content_tag :i, nil, class: names.map{|name| "icon-#{name.to_s.gsub('_','-')}" }
end
end
Example:
glyph(:share_alt)
=> <i class="icon-share-alt"></i>
and
glyph(:lock, :white)
=> <i class="icon-lock icon-white"></i>

Answer 7

Using Rails 4 and Bootstrap 3, here's how to create a delete button using link_to or button_to.
Note that I'm using Haml instead of Erb.
In your view:
- #users.each do |user|
= link_to content_tag(:i, ' Delete', class: "glyphicon glyphicon-trash"),
users_path(user),
class: "btn btn-danger",
method: :delete,
data: { confirm: "Delete user #{user.username}?" }
You can also replace the content_tag part with
raw('<i class="glyphicon glyphicon-trash"> Delete</i>'),

Answer 8

This work for me, (and with confirm message)
<%= button_to "/home/delete?cardId="+card.id.to_s, data: { confirm:'Are you sure you want to delete?' } do %>
<i class="fa fa-times"></i>
<% end%>
this generate
<form class="button_to" method="post" action="/home/delete?cardId=15">
<button data-confirm="Are you sure you want to delete?" type="submit">
<i class="fa fa-times"></i>
</button>
</form>
