hello, i have an input tag, and i want to set the value attribute to either a defined value or a blank string. my python expression either returns a single instance or an empty list.
right now, i am using two Input tags in tandem. Only one remains after rendering b/c one is removed. my question, is it possible to write this so i don't have to have nearly identical Input tags all over my page?
thanks, mark
<input type="text" name="input_name" tal:condition="task/task_name | nothing" tal:attributes="value task/task_name" />
<input type="text" name="input_name" tal:condition="not:exists:task/task_name" tal:attributes="value string:hi" />
The condition seems not to be necessary at all: <input type="text" name="input_name" tal:attributes="value task/task_name | nothing" /> should work for the first example -- well, I have only tested <input type="text" name="input_name" value="some_thing" tal:attributes="value task/task_name | nothing" /> I think the second can be expressed as (not tested): <input type="text" name="input_name" value="hi" tal:attributes="value not:exists:task/task_name | default"> Jim Penny
