Conditional value in ruby on rails?

Question

Hello
I have a form, in which I can set various client fields like client name client address and more.
Only the client name is a must field, and all the other fields can be empty.
After saving the client data I display to the end user the clients details page (with all the clients information).
Now if the address field is empty I want to display some customized text for example "The Address is not set". Currently my "show" page display only this

Address <%=h @client.address %>

So if the address is empty I see nothing.
Can any one tell me how I can add this conditional text?

Answer 1

Try this…

<%- if @client.address.blank? %>
  "The Address is not set"
<%- else %>
  <%=h @client.address %>
<%- end %>

Answer 2

<%=h @client.address.present? && @client.address || "The Address is not set"%>

If you're using it often enough, you may consider making this a helper.

Answer 3

Lots of ways, here's a somewhat messy one

<%=h (@client.address.blank? ? "The Address is not set" : @client.address) %>
