Guys,
I'm trying my best to build a helper that outputs a <'ul> consisting of all the members of a collection. For each member of the collection I want to print out a <'li> that has a title, and a div of links to CRUD the member. This is pretty similar to what Rails outputs for scaffolding for the index view.
Here is the helper I've got:
def display_all(collection_sym)
collection = collection_sym.to_s.capitalize.singularize.constantize.all
name = collection_sym.to_s.downcase
html = ''
html << "<ul class=\"#{name}-list\">"
for member in collection do
html << content_tag(:li, :id => member.title.gsub(' ', '-').downcase.strip) do
concat content_tag(:h1, member.title, :class => "#{name}-title")
concat link_to 'Edit', "/#{name}/#{member.id}/edit"
concat "\|"
concat link_to 'View', "/#{name}/#{member.id}"
concat "\|"
concat button_to 'Delete', "/#{name}/#{member.id}", :confirm => 'Are you sure? This cannot be undone.', :method => :delete
end
end
html << '</ul>'
return html
end
And that output exactly what I want. First of all, if anybody thinks there's a better way to do this, please feel free to correct me, I suspect that I'm doing this in a bass ackwards way, but at the moment its the only way I know how.
I then attempted to wrap the links in a div as follows:
def display_all(collection_sym)
collection = collection_sym.to_s.capitalize.singularize.constantize.all
name = collection_sym.to_s.downcase
html = ''
html << "<ul class=\"#{name}-list\">"
for member in collection do
html << content_tag(:li, :id => member.title.gsub(' ', '-').downcase.strip) do
concat content_tag(:h1, member.title, :class => "#{name}-title")
concat content_tag(:div, :class => "links-bar") do
concat link_to 'Edit', "/#{name}/#{member.id}/edit"
concat "\|"
concat link_to 'View', "/#{name}/#{member.id}"
concat "\|"
concat button_to 'Delete', "/#{name}/#{member.id}", :confirm => 'Are you sure? This cannot be undone.', :method => :delete
end
end
end
html << '</ul>'
return html
end
However, I now no longer get any of the markup inside the div.links-bar output to the view. I'm sure this must have something to do with block and bindings, but I can for the life of me figure out what or how to go about fixing it. Can anybody offer any help?
Thanks,
Joe
