How to DRY REST admin path in URLs?

Rails
1

Hi everyone…

For almost all of my objects I put a series of classic REST admin links
in views. For example, for a ‘user’, I have

<%= link_to “Show”, user_path(user) %>
<%= link_to “Edit”, edit_user_path(user) %>
<%= link_to “Destroy”, user_path(user), :confirm => “Are you sure”,
:method => :delete %>

I am tired of writing those links down over and over and look for a way
to DRY it a little bit.
I am thinking about a helper method allowing me to write a simple

<%= admin_links(user) %>

but I don’t know how to dynamically write the user_path, edit_user_path
and so on?

An idea anyone?

In advance, thank you very much!

Hi Yannis,

You could define a helper method as follows:

def admin_links(user)
“<%= link_to “Show”, user_path(#{user}) %>
<%= link_to “Edit”, edit_user_path(#{user}) %>
<%= link_to “Destroy”, user_path(#{user}), :confirm => “Are you
sure”, :method => :delete %>”
end

In your controller, you would probably define the @user(s) variable
containing either a single user or an array of users. So, in your
view, you would call:

<%= admin_links(@user) %>

or if iterating through an array of users:

<%= admin_links(user) %>

This is untested and I think the helper method might need a little
refining but it shows how to pass the user variable through to
generate the correct links.

The following works (for me) in a simple test:

def admin_links element
text = "

“+link_to(‘Show’, element)+” \n"
text += " “+link_to(‘Edit’,
self.send(“edit_#{element.class.to_s.downcase}_path”, element))+” \n" text += " "+link_to('Destroy', element, :confirm => 'Are you sure?', :method => :delete)+" \n" text end

There may be plugins or gems that already do this, but I haven’t had a
look…

I don’t really like the way I have constructed the edit_XXX_path method
name, in particular because it won’t work for named routes, but it works
for simple standard routes and is a start…

@Robin
Thank you for your answer.
I think my question was not really clear, sorry for that.
In fact I would like to have my admin_links(object) method to accept any
object having resources.
Then I would be able to admin_links(object) and have the links returned
as ‘object’path(object) or edit’object’_path(object).

@Mark
Again, thank you very, much that’s exactly what I was looking for…
