Hi All,
I still get a ticket if I use fields code as mentioned by
Johann (I am using latest stable - web2py 1.99.2 not trunk) , does it
work with the trunk version?
Result1:
fields = (db.projects_post.title, db.projects_posts.project_details,
db.projects_posts.estimated_worth )
TRACEBACK -----------------------
Traceback (most recent call last):
File "D:\WEB2PY\web2py\gluon\restricted.py", line 194, in restricted
exec ccode in environment
File "D:/WEB2PY/web2py/applications/Link_IT/controllers/default.py",
line 159, in <module>
File "D:\WEB2PY\web2py\gluon\globals.py", line 149, in <lambda>
self._caller = lambda f: f()
File "D:/WEB2PY/web2py/applications/Link_IT/controllers/default.py",
line 37, in index
deletable=False, editable=True, csv=False, maxtextlength=64,
paginate=20 )
File "D:\WEB2PY\web2py\gluon\sqlhtml.py", line 1652, in grid
id = row[field_id]
File "D:\WEB2PY\web2py\gluon\dal.py", line 3842, in __getitem__
return dict.__getitem__(self, key)
KeyError: 'id'
#--------------
Result2:
Changing base.css fixed the View rendered by the grid for huge texts
(my Q3 above) - below code/prameter change worked -
.web2py_grid td { white-space:wrap; } /*changed from nowrap to wrap */
Result3: The below code for specifying a custom link works with
web2py(1.99.2) provided you have a valid function called view in your
controller
links = [lambda row: A('View
Post',_href=URL("default","view",args=[row.id]))]
Result4:
Code like below works!
db.projects_posts.id.readable=False # does not show the id in views
May be I'll try with latest web2py in trunk for the fields issue.
Thanks and Regards, Rahul
