Source code for search.html looks like that:
{{extend 'layout.html'}}
{{try:}}{{=H2(message)}}{{except:}}{{=BEAUTIFY(response._vars)}}
{{pass}}
{{=SQLTABLE(items,headers="fieldname:capitalize") if items else
"nothing to see here"}}
The output page looks like that:
form :
No 1:
No 2:
No 3:
No 4:
items :
numbers.id numbers.no_1 numbers.no_2 numbers.no_3 numbers.no_4
nothing to see here
As you can see aliasing is not working at the moment.
Moreover when I put numbers into fields (numbers that are in database)
- nothing happens.
Values are not checked against DB.
I only get flash message: "There are no matching records in Database",
although I know that these numbers are in DB...
Something is missing but I can't figure out what it is.
