How do I embed additional HTML inside of a link_to call?
Here is my desired result:
<i class="icon-show"></i>Show
Here is my link_to call
<%= link_to "Show", exercise_path(exercise) %>
<%= link_to '<i class="icon-search"></i> Show'.html_safe, exercise_path(exercise), :class => 'btn btn-small' %>
.html_safe is required so that it is not escaped.
It is cleaner if you wrap it in a do block
<%= link_to exercise_path(exercise) do %>
<i class="icon-search"></i> Show
<% end %>

I have a partial that takes a column from a database a iterates over it and displays all the urls on the web page. I want to add the lines that I have written in my app/views/topics/show.html.erb page that allow the user to edit, delete, or like the link.
These are the three lines I want to adapt to be added to the partial, the first two are buttons to carry out the edit and delete function and the third is a link to a partial with the like code.
<%= link_to "Edit bookmark", edit_topic_bookmark_path(bookmark.topic, bookmark), class: 'btn btn-primary btn-xs'%><br>
<%= link_to "Delete bookmark", [bookmark.topic, bookmark], method: :delete, class: 'btn btn-danger btn-xs', data: { confirm: 'Are you sure you want to delete this bookmark?' } %>
<%= render partial: 'likes/likes', locals: { bookmark: bookmark } %>
this is the partial I would like to adapt it to located in app/views/bookmarks/_bookmarksandlikes.html.erb
<div>
<h3>
<%y=1%>
<% mark.each do |x| %>
<%=y%>)<%= link_to x.url, x.url%>
<%y=y+1%>
<% end %>
</h3>
</div>
and it is being called from app/views/users/show.html.erb with these two lines.
<%= render partial: 'bookmarks/bookmarksandlikes', locals: { mark: #bookmarks} %>
<%= render partial: 'bookmarks/bookmarksandlikes', locals: { mark: #liked_bookmarks} %>
here is how I have tried to insert the code into the partial
<div>
<h3>
<%y=1%>
<% mark.each do |x| %>
<%=y%>)<%= link_to x.url, x.url%>
<%y=y+1%>
<%= link_to "Edit bookmark", edit_topic_bookmark_path(x.topic, x), class: 'btn btn-primary btn-xs'%><br>
<%= link_to "Delete bookmark", [x.topic, x], method: :delete, class: 'btn btn-danger btn-xs', data: { confirm: 'Are you sure you want to delete this bookmark?' } %>
<%= render partial: 'likes/likes', locals: { x: x } %>
<%end%>
</h3>
when I run the code as is I get an error page that says "undefined local variable or method 'bookmark' for #<#<Class:0x007fdfb1b39c80>:0x007fdfb1988d50> Did you mean? bookmark_url or #bookmarks
and says there is a problem on line 3 of the partial with the code for liking a page in app/views/likes/_likes.html.erb
<% if policy(Like.new).create? %>
<div>
<% if like = current_user.liked(bookmark) %>
<%= link_to [bookmark, like], class: 'btn btn-danger', method: :delete do %>
<i class="glyphicon glyphicon-star-empty"></i> Unlike
<% end %>
<% else %>
<%= link_to [bookmark, Like.new], class: 'btn btn-primary', method: :post do %>
<i class="glyphicon glyphicon-star"></i> Like
<% end %>
<% end %>
</div>
<% end %>
side note at this point in working through this problem, it appears that only the third line for the partial I am trying to insert is giving me problems, the edit and delete buttons are rendering nicely.
Even if you don't know the answer I am quite keen to hear any thoughts on what I am not considering in this question or just your thoughts, also if you need more information please just let me know and I will post more.
Thanks for looking at my question.
I figured out my problem, I could not use the partial because the partial app/views/likes/_likes.html.erb was taking in a different variable than was being passed by app/views/bookmarks/_bookmarksandlikes.html.erb so I just put the needed code into app/views/bookmarks/_bookmarksandlikes.html.erb and adapted it like so.
<div class=row>
<h3>
<%y=1%>
<% mark.each do |x| %>
<%=y%>)<%= link_to x.url, x.url%><br>
<%y=y+1%>
<%= link_to "Edit bookmark", edit_topic_bookmark_path(x.topic, x), class: 'btn btn-primary btn-xs'%><br>
<%= link_to "Delete bookmark", [x.topic, x], method: :delete, class: 'btn btn-danger btn-xs', data: { confirm: 'Are you sure you want to delete this bookmark?' } %><br>
<% if like = current_user.liked(x) %>
<%= link_to [x, like], class: 'btn btn-danger', method: :delete do %>
<i class="glyphicon glyphicon-star-empty"></i> Unlike
<% end %>
<% else %>
<%= link_to [x, Like.new], class: 'btn btn-primary', method: :post do %>
<i class="glyphicon glyphicon-star"></i> Like
<% end %>
<br>
<% end %>
<%end%>
</h3>
</div>
I am trying to replace the word "like" with a heart icon.
Basically, I am trying to add <i class="glyphicon glyphicon-heart"></i> to the following:
<%= link_to 'Like', like_post_path(post), method: :post %>
Try something like
<%= link_to like_post_path(post), method: :post do %>
<i class="glyphicon glyphicon-heart"></i>
<% end %>
This is for you
<%= link_to '<i class="glyphicon glyphicon-heart"></i> Like'.html_safe, like_post_path(post), method: :post %>
Thats the original Devise logout link which works:
link_to("Logout", destroy_user_session_path, :method => :delete)
Because of the and the I had to switch to this kind of link. The problem now is the link try to find the user sign_out
Tried:
<%= link_to (destroy_user_session_path, :method => :delete) do %>
<i class="icon-off"></i> Logout</span>
<% end %>
and
<%= link_to (destroy_user_session_path, method => :delete) do %>
<i class="icon-off"></i> Logout</span>
<% end %>
and
<%= link_to (destroy_user_session_path, :method = 'delete') do %>
<i class="icon-off"></i> Logout</span>
<% end %>
Any ideas or suggestions?
I would do,
<span>
<i class="icon-off">
</i>
<%= link_to("Logout",destroy_user_session_path, :method => :delete)%>
</span>
I'm trying to make link_to function have a css class attached to it,
My code is something like this:
<%= link_to newGame do%>
<%= image_tag newGame.image_url.to_s %>
<% end %>
which links an image to its content, but I need to add a class="thumbnail" to the link,
ie:
<a href="/games/:id" class="thumbnaill>
instead of what its currently generating:
<a href="/games/:id">
Thanks
Ref link_to
<%= link_to newGame, class: 'thumbnail' do %>
Be careful when using the older argument style, as an extra literal hash is needed:
<%= link_to "Articles", { :controller => "articles" }, :id => "news", :class => "article" %>
#Gives Articles
You can just do
<%= link_to newGame, class: 'thumbnail' do %>
<%= image_tag newGame.image_url.to_s %>
<% end %>
I'm trying to pass a link_to block with html but can't get it. I tried some other ways with no luck so I will use my original code:
<% link_to survey_path(survey), :class => "button" do %>
<span>add questions to <%= survey.name %></span>
<% end %>
This doesn't show the :class though.
What needs to be corrected?
Try to add = to make it <%= %>
<%= link_to survey_path(survey), :class => "button" do %>
<span>add questions to <%= survey.name %></span>
<% end %>
In the view code in Rails 3 applications it’s sometimes necessary to
use <%= instead of <% at the beginning of blocks that output content,
such as form_for.
Since it's just a span, why don't you just do
<%= link_to "add questions to #{survey.name}", survey_path(survey), :class => "button" %>
