RUby on rails if else syntax confusion

Question

having trouble with the if else -- I am thinking it is a syntax issue but I can not seem to get it. I used the suggestions below and it is still throwing a 500 error. I do not know the exact error because there is a custom error message and "a 500" is the only technical information given. is there a debug mode that I can enable on the dev side that would provide additional information?

What I am trying to do is display a drop down and allow for a selection if you are a "DSD" otherwise the drop down should be disabled, which is why I need the IF statement.

Here is the current if statement that I am running:

Updated

        <% 
           if (sign_on.acctypw1.strip =="DS") 
               select_tag(:distributor_number_X,  options_for_select(distributors_array), {:style => "width:400px", :disabled => "true"}) 
           else (sign_on.acctypw1.strip =="DSD")               
               select_tag(:distributor_number_X, options_for_select(distributors_array), {:style => "width:400px" })
           end
        %>

here is the error from the server log:

I assume this is in your view (erb.html file) Your if and else statements also have to go inside <% %>.

<% if sign_on.acctypw1.strip =="DS" %>
  <%= select_tag(:distributor_number_X, options_for_select(distributors_array), {:style => "width:400px", :disabled => "true"}) %>
<% else sign_on.acctypw1.strip =="DSD" %>             
  <%= select_tag(:distributor_number_X, options_for_select(distributors_array), {:style => "width:400px" })  %>
<% end %>

Also, something to keep in mind --

<% "This will be evaluated" %>
<%= "This will be evaluated and outputted to your view" %>

You want to use elsif instead of else there.

You also need to wrap your if/elsif/end in <% %> tags as this is ERB

bob kendall Over a year ago

I changed the block of code to the following and I am still getting the logged error above <% if (sign_on.acctypw1.strip =="DS") %> <%=select_tag(:distributor_number_X, options_for_select(distributors_array), {:style => "width:400px", :disabled => "true"}) %> <% elsif (sign_on.acctypw1.strip =="REP") %> <%=select_tag(:distributor_number_X, options_for_select(distributors_array), {:style => "width:400px", :disabled => "false"}) %> <% end %>

<%= 
   if (sign_on.acctypw1.strip =="DS") 
       select_tag(:distributor_number_X,  options_for_select(distributors_array), {:style => "width:400px", :disabled => "true"}) 
   else (sign_on.acctypw1.strip =="DSD")               
       select_tag(:distributor_number_X, options_for_select(distributors_array), {:style => "width:400px" })
   end
%>

this seems the most efficient but still fails a s a 500

bob kendall Over a year ago

no they have a custom error page catching the error and only displaying that it is a 500 is there and extended bug mode I can enable?

Can you ssh into the server and look at the log file? Not much we can do to help without the actual error message.

Why the down vote with no reason? This is a perfectly valid solution as far as i know.
