Hello All,
Currently using Web2Py 2.8.2-stable+timestamp.2013.11.28.13.54.07
I have a simple page for announcing seminars and for downloading
presentation files.
Here are definitions for table, controller and view :
db.define_table("seminars",
Field('sem_date', 'date', label='Date'),
Field('Sem_Time', 'string', label='Time'),
Field('room', 'string', label='Location'),
Field('person', 'string', label='Presenter'),
Field('title', 'string', label='Seminar Title'),
Field('sem_file', 'upload', label='Files', requires=False)
)
db.seminars.sem_file.represent = lambda value,row:A('Download', _href=URL(
'download', args=value))
----------
def index():
db.seminars.id.readable=False
grid = SQLFORM.grid(db.seminars, maxtextlength=150,
details=False, deletable=False, searchable=False,
csv=False, editargs=dict(id=False), formstyle='bootstrap')
grid.element('.web2py_counter', replace=None)
return dict(grid=grid)
----------
{{extend 'seminar_layout.html'}}
{{=grid}}
It works fine as intended. But, I want to replace "Download" link with "No
Files Available" and disable the link when there are there are no files
available. Any suggestion or help is appreciated.
Thanks,
PT
