[web2py] Re: return all results for a field if no query.
every db.table.column == parameter is something that further reduces the resultset (it's a "filter" condition) in case "parameter" is 0, just don't use that condition in the query ^_^ moreover, you can do filter_condition = (db.table.created_by == auth.user_id) if . filter_condition = filter_condition & (db.table.field_a == something) filtered_set = db(filter_condition).select() PS: usually filters are more "manageable" with request.vars than request.args() ... it's a little unconfortable to remember the order of the filter and to specify 0 as the "ALL" parameter is counterintuitive eco/0/1/0/6/0/0 sounds a lot more ugly than eco?b=1&d=6 On Saturday, February 22, 2014 7:28:33 PM UTC+1, Avi A wrote: > > Hi, > Assuming I want to create an ajax query that will filter the results > according to some data in fields: > for example: ajax url: ... eco/1/6/4/5/3 > > def eco: > my_content = db.table.created_by == auth.user.id > query_a = db.table.field_a == request.args(0) > query_b = db.table.field_b== request.args(1) > query_c = db.table.field_c == request.args(2) > query_d = db.table.field_d == request.args(3) > query_e = db.table.field_e == request.args(4) > > filtered_list = db((my_content) & (query_a) & (query_b) & (query_c) & > (query_d) & (query_e)).select(,) > return dict(filtered_list = filtered_list) > I guess, so far so good. > > Now if any arg == 0 , (for example: eco/2/0/0/0/3) I want it to skip that > specific query. > > So I want to a chive something like that: > if request.args(0) != 0: > query_a = db.table.field_a == request.args(0) > else: > query_a = db.table.field_a == ALL >if request.args(01) != 0: > etc"... > > with what should I replace the ALL? or the else part? > > Thanks. > > > > > > > > > > > > > > > > > -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups "web2py-users" group.

Great, thanks. the "moreover" idea is what i was missing. Yeah, I'll replace the args with vars url, thanks.

[web2py] Re: return all results for a field if no query.
If you make sure your URL vars have the same names as the associated table fields, you can simplify further as follows: def eco: my_content = db.table.created_by == auth.user.id filter_query = reduce(lambda a, b: a & b, [db.table[v] == request.vars[v] for v in request. vars if v in db.table.fields]) filtered_list = db(my_content & filter_query).select(,) return dict(filtered_list = filtered_list) or if you prefer loops: def eco: filter_query = db.table.created_by == auth.user.id for var in [v for v in request.vars if v in table.fields]: filter_query &= db.table[var] == request.vars[var] filtered_list = db(my_content & filter_query).select(,) return dict(filtered_list = filtered_list) Anthony On Saturday, February 22, 2014 3:25:34 PM UTC-5, Avi A wrote: > > Great, thanks. the "moreover" idea is what i was missing.
