Hello,
I am facing an error when using web2py sqlform.grid that I am not
understanding why.
I have the controller where I define the form:
def search_records():
if request.vars:
selectable = request.vars.z
DBconn = db._uri
name = searchtable(selectable)
try:
form = SQLFORM.grid(query=name, orderby=None, searchable=True,
sortable=True, paginate=20, deletable=True,
editable=True, details=True, selectable=None,
user_signature=False, create=True, csv=False,
links=None, links_in_grid=True, maxtextlength=100,
sorter_icons=('[^]', '[v]'),
ui='jquery-ui', showbuttontext=True,
_class="web2py_grid", formname='web2py_grid',
search_widget='default', ignore_rw=True)
response.view = 'default/search_records.html'
except:
redirect(URL('default', 'index'))
return dict(form=form, selectable=selectable)
the function searchtable returns the table to present in the grid, so the
variable name is spmething like: db.TABLE_TO_PRESENT
The view page returns what is expected with the respective links "add
record", "view", "edit" and "delete. The error comes when I use the link
"add record" or "edit". After opining the correct page to insert the data,
when clicking submit it shows the error:
1.
2.
3.
4.
5.
6.
7.
8.
9.
10.
Traceback (most recent call last):
File "...\web2py\gluon\restricted.py", line 227, in restricted

line 36, in search_records
return dict(form=form, selectable=selectable)
UnboundLocalError: local variable 'form' referenced before assignment
So it seems that it loses the information relative to that form that was
previously loaded.
I am trying to understand the reason for this but I can't get to any
conclusion. Can anyone help me?
Thank you.
