Python Bottle - Inline IF statements in Template

Question

Make = <SELECT name="where_make">
        % for make in makes:
            <OPTION value="{{make}}" 
            % if make == defaults['make']:
                selected="selected"
            % end
            >{{make}}</option>
        %end

How can I do this if statement on a single line?

Answer 1

Bottle's built-in template engine supports inline if statements:

<option value="{{make}}" {{!'selected="selected"' if make == defaults['make'] else ""}}>{{make}}</option>

Note the exclamation mark before the selected="selected" - it tells the template engine not to escape quotes.

Demo:

from bottle import SimpleTemplate

tpl = SimpleTemplate("""Make = <SELECT name="where_make">
        % for make in makes:
            <option value="{{make}}" {{!'selected="selected"' if make == defaults['make'] else ""}}>{{make}}</option>
        %end""")
print tpl.render(make='test', defaults={'make': 'test'}, makes=['test'])

prints:

Make = <SELECT name="where_make">
            <option value="test" selected="selected">test</option>

Hope that helps.
