    - by Matt Campbell
    I am trying to remove a file from a dependency jar that I am including in my war file in maven.

  • Automark model names/attributes for translation

    - by Saosin
    Is there any way one could automatically mark all model names and attributes for translation, without specifying verbose_name/_plural on each one of them? Doesn't feel very DRY to do this every time: class Profile(models.Model): length = models.IntegerField(_('length')) weight = models.IntegerField(_('weight')) favorite_movies = models.CharField(_('favorite movies'), max_length=100) favorite_quote = models.CharField(_('favorite quote'), max_length=30) religious_views = models.CharField(_('religious views'), max_length=30) political_views = models.CharField(_('political views'), max_length=30) class Meta: verbose_name = _('profile') verbose_name_plural = _('profiles')

  • How to check WCF generated client is compatible with service at runtime

    - by Schneider
    I realise that WCF and services in general are meant to be loosely coupled. But I have a requirement that my client app can check whether an given WCF endpoint contains a service that matches its generated client code. In other words I need to check for a compatible service. Obviously I could have a method that returns a manually maintained version number, but I would prefer not to have to write my own meta data system if WCF can do something out of the box.

    - by joozek
    I have an 'order' Model: class Order(models.Model): date_time=models.DateTimeField() # other stuff And I'm using Django ModelForm class to render a form, but I want to display date and time widgets separately. I've came up with this: class Form(forms.ModelForm): class Meta: model = Order exclude = ('date_time',) date = forms.DateField() time = forms.TimeField() The problem is that I want to put these fields somewhere between 'other stuff'

  • getting Cannot identify image file when trying to create thumbnail in django

    - by Mo J. Mughrabi
    Am trying to create a thumbnail in django, am trying to build a custom class specifically to be used for generating thumbnails. As following from StringIO import StringIO from PIL import Image class Thumbnail(object): source = '' size = (50, 50) output = '' def __init__(self): pass @staticmethod def load(src): self = Thumbnail() self.source = src return self def generate(self, size=(50, 50)): if not isinstance(size, tuple): raise Exception('Thumbnail class: The size parameter must be an instance of a tuple.') self.size = size # resize properties box = self.size factor = 1 fit = True image = Image.open(self.source) # Convert to RGB if necessary if image.mode not in ('L', 'RGB'): image = image.convert('RGB') while image.size[0]/factor > 2*box[0] and image.size[1]*2/factor > 2*box[1]: factor *=2 if factor > 1: image.thumbnail((image.size[0]/factor, image.size[1]/factor), Image.NEAREST) #calculate the cropping box and get the cropped part if fit: x1 = y1 = 0 x2, y2 = image.size wRatio = 1.0 * x2/box[0] hRatio = 1.0 * y2/box[1] if hRatio > wRatio: y1 = int(y2/2-box[1]*wRatio/2) y2 = int(y2/2+box[1]*wRatio/2) else: x1 = int(x2/2-box[0]*hRatio/2) x2 = int(x2/2+box[0]*hRatio/2) image = image.crop((x1,y1,x2,y2)) #Resize the image with best quality algorithm ANTI-ALIAS image.thumbnail(box, Image.ANTIALIAS) # save image to memory temp_handle = StringIO() image.save(temp_handle, 'png') temp_handle.seek(0) self.output = temp_handle return self def get_output(self): return self.output.read() the purpose of the class is so i can use it inside different locations to generate thumbnails on the fly. The class works perfectly, I've tested it directly under a view.. I've implemented the thumbnail class inside the save method of the forms to resize the original images on saving. in my design, I have two fields for thumbnails. I was able to generate one thumbnail, if I try to generate two it crashes and I've been stuck for hours not sure whats the problem. Here is my model class Image(models.Model): article = models.ForeignKey(Article) title = models.CharField(max_length=100, null=True, blank=True) src = models.ImageField(upload_to='publication/image/') r128 = models.ImageField(upload_to='publication/image/128/', blank=True, null=True) r200 = models.ImageField(upload_to='publication/image/200/', blank=True, null=True) uploaded_at = models.DateTimeField(auto_now=True) Here is my forms class ImageForm(models.ModelForm): """ """ class Meta: model = Image fields = ('src',) def save(self, commit=True): instance = super(ImageForm, self).save(commit=True) file = Thumbnail.load(instance.src) instance.r128 = SimpleUploadedFile( instance.src.name, file.generate((128, 128)).get_output(), content_type='image/png' ) instance.r200 = SimpleUploadedFile( instance.src.name, file.generate((200, 200)).get_output(), content_type='image/png' ) if commit: instance.save() return instance the strange part is, when i remove the line which contains instance.r200 in the form save. It works fine, and it does the thumbnail and stores it successfully. Once I add the second thumbnail it fails.. Any ideas what am doing wrong here? Thanks Update: I tried earlier doing the following but I still got the same error class ImageForm(models.ModelForm): """ """ class Meta: model = Image fields = ('src',) def save(self, commit=True): instance = super(ImageForm, self).save(commit=True) instance.r128 = SimpleUploadedFile( instance.src.name, Thumbnail.load(instance.src).generate((128, 128)).get_output(), content_type='image/png' ) instance.r200 = SimpleUploadedFile( instance.src.name, Thumbnail.load(instance.src).generate((200, 200)).get_output(), content_type='image/png' ) if commit: instance.save() return instance

  • PHP: Which DB/DB Engine supports search well?

    - by KeyStroke
    Hi, I'm starting a site which relies heavily on search. While it's probably going to search basic meta data in the beginning, it might grow to something bigger in the future.

  • How to configure DB connection in a Servlet based JPA application

    - by deamon
    By default DB connections of JPA applications are configured in the META-INF/persistence.xml, when the application is not deployed to a full Java EE application server. In my opinion it is not very elegant to place such environment specific configuration into a file that is inside a .war file. How could a DB connection of a Servlet based JPA application be configured more flexible (=outside of the .war file)?

  • Is there a web tool framework for building a video editing/manipulation widget other than custom Fla

    - by Brandon
    I am looking to build a widget for a site which allows users to tag images from individual frames of a video file but would prefer not to have to build a custom Flash tool. Is there an existing free library or framework which simplifies things like this in a webapplication setting? Features would also involve basic video playback functionality as well as time-driven meta-data and the ability to extract images from individual video frames. Are there existing open-source web-based tools for video manipulation other than building your own custom Flash app?

  • Video playback with jQuery Mobile and Phonegap

    - by aritchie
    I'm fairly new to mobile apps, so am trying to knock up a simple video player using Phonegap and jQuery Mobile. The problem is, jQuery mobile appears to be blocking the video playback for some reason. To troubleshoot I stripped it right back to the following HTML, but get the same result, ie a black rectangle where the video should be, but no video playback or controls. <!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <meta name="viewport" content="width=device-width,initial-scale=1"/> <link rel="stylesheet" type="text/css" href="css/index.css" /> <link rel="stylesheet" href="css/jquery.mobile-1.2.0.min.css" /> <script type="text/javascript" src="cordova-2.2.0.js"></script> <script type="text/javascript" src="js/index.js"></script> <script src="js/jquery-1.8.3.min.js"></script> <script src="js/jquery.mobile-1.2.0.js"></script> <title></title> </head> <body> <div> <video controls autoplay> <source src="video/video1.mp4" type="video/mp4" > </video> </div> </body> </html> If I remove the link to jquery.mobile-1.2.0.js the video shows up and plays, otherwise, just the black rectangle. I don't know jQuery mobile at all, but searching in the js for a reference to the video elements doesn't show up, so I've no idea what is blocking it. The code works fine in Chrome and Firefox. There are no console messages in Xcode. I also tried hooking up to http://debug.phonegap.com/ but this gave no error messages either. Any ideas??

  • My login controller doesn't work. Problem with fetching username.

    - by misterwebz
    Currently my login controller doesn't work because i can't seem to fetch the username and password. I'm currently using something like this: form_username = str(request.params.get('username')) db_user = meta.Session.query(User).filter_by(username=form_username) if db_user is None: return redirect('auth/error') No matter which username is use, db_user always returns True and thus never goes to auth/error. I used the shell to play with this and i was able establish a connection with the database, so i'm not sure what i'm doing wrong here.

  • Redirecting users in JSP from within a includes - java syntax error

    - by Mark Hazlett
    Hey everyone, So my setup for my web application is that I have a general header and footer and then I just include them in all my other pages so that all the common elements for all the pages are in a single page. The only problem I'm running into is when I want to redirect the user back to a login page if the "username" session has not already been created. The problem that I"m running into is that I have an if statement at the top of my header.jsp and then I have the else in the footer.jsp and it is giving me a java syntax error. Any ideas? Here is the code I'm referring to... <%@page contentType="text/html" pageEncoding="UTF-8"%> <% if(session.getAttribute("username") != null) { %> <%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"> <!-- CSS files --> <link rel="stylesheet" href="../CSS/headerStyle.css" type="text/css" media="screen" /> <title>Insert title here</title> </head> <body> <div id="container"> <div id="header"> <div id="headerTitle">Title</div> </div> </div> <%} %> And then here is the footer <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <link rel="stylesheet" href="../CSS/headerStyle.css" type="text/css" media="screen" /> </head> <body> <div id="footer"></div> </body> </html> <% else { response.sendRedirect("../wa_login/login.jsp"); } %> However it is giving me an error on the else statement because the else doesn't have an if statement because it's in the header file.

    - by Thierry Lam
    I have the following dictionary: sites = { 'stackoverflow': 1, 'superuser': 2, 'meta': 3, 'serverfault': 4, 'mathoverflow': 5 } To check if there are more than one key available in the above dictionary, I will do something like: 'stackoverflow' in sites and 'serverfault' in sites The above is maintainable with only 2 key lookups. Is there a better way to handle checking a large number of keys in a very big dictionary?

  • Unable to fetch Json data from remote url

    - by user3772611
    I am cracking my head to solve this thing. I am unable to fetch the JSON data from remote REST API. I need to fetch the JSOn data nd display the "html_url" field from the JSON data on my website. I saw that you need the below charset and content type for fetching JSON. <html> <head> <meta charset="utf-8"> <meta http-equiv="content-type" content="application/json"> </head> <body> <p>My Instruments page</p> <ul></ul> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3/jquery.min.js"></script> <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.10.3/jquery-ui.min.js"></script> <script type="text/javascript" src="http://code.jquery.com/jquery-1.11.0.min.js"></script> <script type="text/javascript"> $(document).ready(function () { alert("Inside the script"); $.getJSON(" https://pki.zendesk.com/api/v2/help_center/sections/200268985/articles.json", function (obj) { alert("Inside the getJSON"); $.each(obj, function (key, value) { $("ul").append("<li>" + value.html_url + "</li>"); }); }); }); </script> </body> </html> I referred to following example on jsfiddle http://jsfiddle.net/2xTjf/29/ The "http://date.jsontest.com" given in this example also doesn't work in my code. The first alert is pops but not the other one. I am a novice at JSON/ Jquery. i used jsonlint.com to find if it has valid JSON, it came out valid. I tested using chrome REST client too. What am I missing here ? Help me please ! Thanks in anticipation.

    - by JNM
    I am trying to create a very simple phone gap application for iOS. I am using query mobile. the problem is, that i can't get javascript event to fire on button click. Code i have now: <!DOCTYPE html> <html> <head> <title>Title</title> <meta name="viewport" content="width=device-width, minimum-scale=1, maximum-scale=1"> <meta charset="utf-8"> <link rel="stylesheet" type="text/css" href="js/jquery.mobile-1.2.0.css" /> <script type="text/javascript" charset="utf-8" src="cordova-1.8.1.js"></script> <script type="text/javascript" charset="utf-8" src="js/jquery-1.8.2.min.js"></script> <script type="text/javascript" charset="utf-8" src="js/jquery.mobile-1.2.0.min.js"></script> <script type="text/javascript"> document.addEventListener("deviceready", onDeviceReady, false); function onDeviceReady() { } function showAlert() { navigator.notification.alert("Cordova is working"); } </script> </head> <body> <div data-role="page" id="options" data-add-back-btn="true" data-back-btn-text="Atgal"> <div data-role="header" data-position="fixed"> <h1>Title</h1> </div> <div data-role="content"> <h1>Alert</h1> <p><a href="#" onclick="showAlert(); return false;" data-role="button">Show alert</a></p> </div> </div> </body> </html> I tried multiple solutions to fix my problem, but none of them works. When have button with # in href, it doesn't event change the color on click. When i add url, it changes color. But it never call javascript function. Another problem is, that document.addEventListener("deviceready", onDeviceReady, false); works only in the index page. If i press button in initial page which redirects to another page, OnDeviceReady function is never called. Anybody has any ideas?
