Conditional statements in rhtml

Rails
1

Hello i was wondering is there was any way of using an IF statement in a
.rhtml…?

So far i have this:

State: <%= if @boards.running == "1" render :text => "Running" %>

What i want to do is to evaluate a column’s value and depending on its
value render a text. On the line above i want to render Running if
@boards.running is == 1 else render Waiting…?

Can i do that the way i looking at it…?

Any ideas…

Thanks

You can embed any ruby code in RHTML - that is what the R stands for -
by putting the code in between <% %> or <%=%>

Try this:

State: <%if @boards.running == "1" %> <%= render :text => "Running" %> <%else%> <%= render :text => "Waiting" %> <%end%>

you might be able to embed the whole code block in a <%=%> - give it a
try.

Hummm… That didnt work… It didnt give me any errors, but the test
wont show up…

here is what i have:

State:
<% if @boards.running == “1” %>
<%= render :text => “Running” %>
<% else %>
<%= render :text => “Waiting” %>
<% end %>

I also tried:

State: <%= render
:action => ‘state’ %>

and in the controller i have
def state
bstate = Boards.find(@params[“id”])

        if bstate.running == "1"
            render :text => "Running"
        else
            render :text => "Waiting"
        end
    end

None of them worked, yet it didnt give me any errors…

Any ideas…?

Thanks

<%= @boards.running==1?‘Running’:‘Waiting’ %>

The excess %><% freak me out.

     <%= render :text => if @boards.running == "1"
         "Running"
     else
         "Waiting"
     end %>

Idiomatic but legible!

It is basically the same thing…

1==“1”
=> false

1==“1”
=> false

That’s one thing. Second: you shouldn’t use render :text in .rhtml
templates. I does not work there (AFAIK).
