Since I'm using Paperclip, I will ask as follows:
I have the following in my model and view. What should I place instead
of ????? in the view (show.html.erb)?
*Model:
class Dicom < ActiveRecord::Base
has_attached_file :photo, :styles => {:original => ["100%", :jpg]}
def getHeight()
uploaded_file = photo.queued_for_write[:original]
dimensions = Paperclip::Geometry.from_file(uploaded_file)
height = dimensions.height
return height
end
def getWidth()
uploaded_file = photo.queued_for_write[:original]
dimensions = Paperclip::Geometry.from_file(uploaded_file)
width = dimensions.width
return width
end
end
* View:
<%= javascript_include_tag "coordinate" %>
<canvas id="draw" height= "<%=????? %>" width="<%=????? %>" >
</canvas>
<p id="notice"><%= notice %></p>
<p>
<b> Name </b>
<%= @dicom.name %>
</p>
<p>
<b> Image </b>
</p>
<div id="image_element" style="display: none;">
<p>
<%= image_tag @dicom.photo.url , :id => 'dicom_image' %>
</p>
</div>
<%= update_page_tag do |page|
page << "drawImg();"
end
%>
<%= update_page_tag do |page|
page << "drawLine();"
end
%>
<%= link_to 'Edit', edit_dicom_path(@dicom) %>
<%= link_to 'Back', dicoms_path %>
