django models - Cannot resolve keyword '_icontains' into field -


for search function in django application, i'm using following statement query database fields containing search term:

search_results = post.objects.filter(name_icontains=search_term)

however, error:

cannot resolve keyword 'name_icontains' field. choices are: content, date, id, name, url, views

these contents of models.py file reference:

import datetime  django.db import models  class post(models.model):     name = models.charfield(max_length=200)     content = models.textfield()     date = models.datefield(default=none, blank=true, null=true)     url = models.charfield(max_length=5, default=none, blank=true, null=true)     views = models.integerfield(default=0)      def __str__(self):         return self.name

i'm following method searching it's described in documentation. doing wrong?

try doing double underscore:

search_results = post.objects.filter(name__icontains=search_term)                                           ^

see the docs field lookups in django more detailed information icontains , other filters.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

Why does math.random(999999999999) returns 1 in Lua? -

i tried: print(math.random(999999999999)) , has printed 1 . also math.random() includes 999999999999 printing same thing. examples: print(math.random(1.999999999999)) » 1 print(math.random(1999999999999)) » 1 for k,v in next,{math.random(999999999999), math.random(1999999999999), math.random(2.999999999999)} print(v) end » 1 local n = math.random(999999999999) print(n==1) » true then think understood (if know lua of course). can explain me? @edits: the lua version i'm using 5.2. i tried print(math.random(-999999999999)) , printed 111711452 . looks worked positive number. this problem surely because math.random treats input arguments passed in lua 5.1 and/or 5.2. [mathlib.c] 1 : as may know in c , standard int can represent values -2,147,483,648 2,147,483,647 . adding +1 2,147,483,647 , in use-case, overflow , wrap around value giving -2,147,483,648 . end result negative since you're multiplying positive negative number. ther...
