python - get_template_names(self) doesn't work in TemplateView -


i'm trying use pdfview django-pdfkit. problem don't have 1 template. instead have 4 templates. template chosen depends on request.get parameter.

so i've created view called test extends pdfview.

class test(pdfview):      def get_template_names(self):         # don't bother chosing template         return ["pdf/dobropis_pdf_template.html"]      def get_context_data(self, **kwargs):         doklad = get_object_or_404(doklad, pk=self.request.get.get('id'))         return {'doklad':doklad}

the problem if don't specify template_name, returns:

templatedoesnotexist @ /render/doklad/ none

so suppose get_template_names method isn't called.

why so? how can make work?

this urls.py:

url(r'^render/doklad/', views.test.as_view(), name="doklad_to_pdf"),

this pdfview (in case helps):

class pdfview(templateview):     #: set change filename of pdf.     filename = none      #: set default pdf display inline.     inline = false      #: set pdfkit options dict.     pdfkit_options = none      def get(self, request, *args, **kwargs):         """         return httpresponse either of pdf file or html.          :rtype: httpresponse         """         if 'html' in request.get:             # output html             content = self.render_html(*args, **kwargs)             return httpresponse(content)          else:             # output pdf             content = self.render_pdf(*args, **kwargs)              response = httpresponse(content, content_type='application/pdf')              if (not self.inline or 'download' in request.get) , 'inline' not in request.get:                 response['content-disposition'] = 'attachment; filename=%s' % self.get_filename()              response['content-length'] = len(content)              return response      def render_pdf(self, *args, **kwargs):         """         render pdf , returns bytes.          :rtype: bytes         """         html = self.render_html(*args, **kwargs)          options = self.get_pdfkit_options()         if 'debug' in self.request.get , settings.debug:             options['debug-javascript'] = 1          kwargs = {}         wkhtmltopdf_bin = os.environ.get('wkhtmltopdf_bin')         if wkhtmltopdf_bin:             kwargs['configuration'] = pdfkit.configuration(wkhtmltopdf=wkhtmltopdf_bin)          pdf = pdfkit.from_string(html, false, options, **kwargs)          return pdf      def get_pdfkit_options(self):         """         returns ``self.pdfkit_options`` if set otherwise default dict of options supply pdfkit.          :rtype: dict         """         if self.pdfkit_options not none:             return self.pdfkit_options          return {             'page-size': 'a4',             'encoding': 'utf-8',         }      def get_filename(self):         """         return ``self.filename`` if set otherwise return template basename ``.pdf`` extension.          :rtype: str         """         if self.filename none:             name = splitext(basename(self.template_name))[0]             return '{}.pdf'.format(name)          return self.filename      def render_html(self, *args, **kwargs):         """         renders template.          :rtype: str         """         static_url = '%s://%s%s' % (self.request.scheme, self.request.get_host(), settings.static_url)         media_url = '%s://%s%s' % (self.request.scheme, self.request.get_host(), settings.media_url)          override_settings(static_url=static_url, media_url=media_url):             template = loader.get_template(self.template_name)             context = self.get_context_data(*args, **kwargs)             html = template.render(context)             return html

by overriding get, you've bypassed all built-in functionality view, including calling of get_template_names. right thing do.

however, given code you've shown, what's reason why can't call method render_html? or inline logic there.

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...

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
