Django model property geo distance -

-

I am trying to apply the proximity search based on latitude and longitude using Django and Postgresql. I have an abstract version of the model. Class items (models.Model): "" "Dossstrings for items" "uuid = UUIDField (primary_key = true, auto = true) name = model.carfild (_ (" name " ) = = Model = _Keyfield (_ ('location'), max_length = 40, and the address = Blank = true, null = true) @property def geo_distance (self, location = none): if the location is nothing: cursor = connection.cursor () cursor.xicute ("SELECT geo_distance CAST ('% s')) POINT , CAST ('% s' AS POINT) "% self.location, location) return round (float (curse) .itchin) * 1.621371192237), 2)

I want to be able to do something like this, such as view.py: 

  items = Item.Abject.Filter (name__istartwith = "anything") Results = [] Items in items for: results.append ({'name': item.name, 'distance': item.geo_distance ("(11.23123, -12.123213 ) ")}))

I welcome any suggestion that this is not the best way.

If you search based on latitude and longitude then I would recommend you. You can use to calculate the distance between point two or the surrounding area from the point of the point. It is better to write the calculation of distance by using it. For my information, the Django does not support the process of making the process; I did some benchmark in terms of distance calculation, instead of computing the end of the digengo, the processes got faster. Good Luck.

c# - How to capture HTTP packet with SharpPcap -

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.

jquery - SimpleModal Confirm fails to submit form -

-
I am trying to confirm jQuery to show yes / no confirmation when I submit a form. I had modified (in the last list) to capture and block form submissions. However, it only works with jQuery 1.2.6, a recent upgrade stops 1.3.2, if yes is clicked, then by submitting the form. But I can not understand what is wrong / inconsistent in my code now. Demo (which works in both versions of a simple window.href implementation). $ (document) .ready (function () {$ ('input.delete'). Click (function (e) {e.preventDefault (); var target = $ (e .target); Confirm ("Really delete this event?", Function () {target.click ()});});}); How about something like this? The idea of ​​catching clicks (and fire!) On the submitted event is not click event. $ (document) .ready (function () {$ ('# myForm'). Submit (function () {var f = this; Confirm (" Remove? ", Function () {$ (f). Submit ();}) Return; Return the initial session;}}}}; Hope That this is som

By using Wordpress I have created a multiple selection box so that users can select categories to exclude. When the page is initially loaded, I see my predefined default option.
