i creating application in django , have next problem. have search forms in application, , in of them there fields of type 'datefield'. in addition, have implemented jquery function display calendar view when user clicks on date fields. code next: <script> $(function() { $( ".vdatefield" ).datepicker({ dateformat: 'yy-mm-dd' }).val(); }); </script> the problem doesn't work always. in pages, calendar view displayed correctly, in few others not. have put correctly class 'vdatefield' datefield attributes in forms in django this: self.fields['date'].widget.attrs = {'class': 'vdatefield'} so, why doesn't work? thank much! try wrap code in $(document).ready e.g. <script> $(document).ready(function(){ $(function() { $( ".vdatefield" ).datepicker({ dateformat: 'yy-mm-dd' }).val(); }); }); </script>

trying create view tables have same fields different data in them. have table track each of these tables, , track ones active. want view tie active tables in 1 view. say have tables a, b, , c. b , c active, table 1 lists each table , active. form table 1 can table names need view. it escapes me on how on sql server (2008 version) this sound bad design. better store data in 1 table , use partitioning methods access it. here, though, 1 method want: create view abc select a.* cross join (select 1 table1 status = 'active' , tablename = 'a') union select b.* b cross join (select 1 table1 status = 'active' , tablename = 'b') select c.* c cross join (select 1 table1 status = 'active' , tablename = 'c'); i don't recommend approach. intended show possible. chose cross join , because subquery evaluated once , might optimization underlying execution code.

i have list of color values (in either of formats: hex ('#ffffff') or rgb (255,255,255) if helps). these colors correspond explicitly line segment between points. plot line collection of line segments via: import matplotlib.pyplot plt import itertools colors = itertools.cycle('#ffffff', '#ffffff', '#ff0320', '#452143', ...) t = (0, 1, 2, 3, ...) var1 = (43, 15, 25, 9, ...) ax = plt.subplot2grid((3,1), (0,0), colspan=3, rowspan=1) ps = [(t,var1) (t,var1) in zip(t, val)] start, end in zip(ps[:-1], ps[1:]): t, var1 = zip(start, end) c = next(colors) ax.plot(t, var1, color=c) however since have color each point prefer set cmap plot. how might accomplish converting list of colors cmap can use when plotting line? as tcaswell says, use linecollection this: import numpy np matplotlib import pyplot plt matplotlib.collections import linecollection # random walk xy = np.cumsum(np.random.randn(1000, 2), axis=0) z = np.l

new formatting lets this: '{:.<12}'.format('##') - optional fill character. can using old formatting? (i know can fill spaces '%-12s' % '##' ) also, old formatting lets this: '%-*s' % (12, '##') - variable length. can using new formatting? for doing variable length using new-format , can use nesting of replacements - >>> '{:{}<{}}'.format('##','.',12) '##..........' >>> '{:{}<{}}'.format('##','-',12) '##----------' >>> '{:{}<{}}'.format('##','-',20) '##------------------' even spaces fill character - >>> '{:{}<{}}'.format('##',' ',20) '## ' please note not need use nesting of replacements, can directly specify them in format - >>> '{: <12}'.format('##') '## ' you can sp

i reading javascript tutorial , searching functions on mdn website when stumbled across example of math.random() : function getrandomintinclusive(min, max) { return math.floor(math.random() * (max - min + 1)) + min; } while understand math.floor chooses biggest number , erases numbers have decimal values, learnt function called parseint() deletes of numbers after point. so, what's difference between two? couldn't use function getrandominclusive(min, max) { return parseint(math.random() * (max - min + 1)) + min; } instead? got idea while writing question math.floor() might write 5 when it's 4,5 , parseint() write 4, it's not important random number generator understand (if know examples of when important, please tell me!) so, there's still not of difference in case? parseint parses string integer, reading digits @ beginning of string. not appropriate use round number integer. number converted string first, unexpected results: var num =

i have following table: column a: time stamps column b-d: different values column e: indicators column g: converted time stamps calculate (min sec) i need assign different values indicators (column f). first sequence xyz gets 1, second 2, ect. shown in image. however, if gets more complicated can have missing values. for example rows 11 17 might not exist , indicator left z (which gets 2 assigned). in worst case, rows 11 20 missing. next sequence 3 needs assigned. thus, somehow need work column "g" due missing values time stamp 'jumps' indicator in column "i". i tried use if functions 1 if indicator or time changes. combine , how can work in loop... does know deal or has idea? in actual table have around 12 rows per second. gives >16,000 rows per file. after assignment goal make pivot table different values , assignments (this works already).

i developing chat app. when user connects internet, server pushes message notifications him. should use service or intentservice new message notifications? service/intentservice must start on boot , never stop, if close app. i expect if using own push notification system, it's based on keeping connection/socket open backend. you'll have on background thread because android doesn't allow network operations on main thread. intentservice queues start commands (issued via context.startservice() ) , executes them serially on background thread; once queue exhausted stops automatically. useful performing relatively short-lived tasks off main thread , in context less erratic lifecycle activity. doesn't sound best fit must alive, think should stick regular service , manage own worker thread keep network operations in background.
