Django Image gallery
I'm trying to make a image gallery template in Django that will pull in new images when they are added to the blog. What I'm wanting are three or four columns of thumbnail sized images in a grid. So far my template looks like this {% for image in images %} {% if forloop.first %} <tr> {% endif %} <td> <a href="{{ image.get_absolute_url }}"> <img src="{{ image.image.url }}" class="img-responsive img-thumbnail" width="304" height="236"/></a> </td> {% if forloop.last %} </tr> {% else %} {% if forloop.counter|divisibleby:"4" %} </tr><tr> {% endif %} {% endif %} {% endfor %} However this won't allow me to manipulate the images as easily as I would like I was hoping to use Bootstraps columns but each time I try that it gives me the images in a single column. -

Django test - Get messages in HttpReponseRedirect with view call (so no follow = True)
I'm trying to test a login view, here is the test code: #test login view class LoginViewTest(TestCase): def setUp(self): self.client = Client() self.factory = RequestFactory() self.user = User.objects.create_user('user_test', 'user_test@test.com', 'pws_test') #self.browser = webdriver.Firefox() def test_successful_login(self): activate('en') request = self.client.post('/en/account/login/', {'username': 'user_test', 'password': 'pws_test'}, follow=True) request.user = self.user response = my_login(request) m = list(response.context['messages']) self.assertEqual(len(m), 1) self.assertEqual(str(m[0]), 'Login successfull') self.assertTrue(response.context['user'].is_active) self.assertRedirects(response, '/en/') And the error message: 'HttpResponseRedirect' object has no attribute 'context' I want to check if the message is correctly sent in case of successful login, but I am unable to access messages as my_login is a HttpRedirectResponse (as the login is successful), and I cannot simply set follow = True as I am directly calling a view and not a self.client.post. Does anyone have a solution ? Thanks -

Django: save() method in form or model?
quite a generic question here but I was curious as to when and in what cases would you use a save method in a ModelForm over the Model class itself and vice versa? model: class Model(models.Model): ... def save(self, *args, **kwargs): super (Model, self).save(*args, **kwargs) modelform: class ModelForm(forms.ModelForm): ... def save(self, commit=True): model = super(ModelForm, self).save(commit=True) if commit: model.save() return model Thanks! -

Storing several images in article in Django
I create a Django app which has articles, currently stored as html in a text-field in the model. In template I show them using {{article.text|safe }}. But I need to be able to put images in any place of acrticle: different quantity to each article or none to some of them. I see following options to do that: To store html-text including <img src='...'> in database (and loose the opportunity to use django staticfiles in this case?)... To create ImageField (or several) in model - in this case I will have limited fixed number of images for each article and new questions - how to put images inside html-content (not above or below). To store prepared articles htmls with images as staticfiles - get problems with access and loose the ability to edit content rapidly using django admin panel (ex. to fix a typo). To use WYSIWYG-editor with possibility to upload images in django admin. This post tells about django-adminfiles but it was last updated in 2013 and doesn't work in Django 1.9 and later (I use 1.11). Even if find a modern plugin like that - main problem is that content is currently beeing prepared by other people having … -

Do I have to isolate my wsgi.py from my django project folder?
where should I place my wsgi.py? Do I have to isolate it from my django project folder? Should I move my django project folder outside of my home directory? Currently I copied my django project folder to /home/username/djangosites/project/ and my wsgi.py is in the folder /home/username/djangosites/project/project/ In the same folder there are files like settings.py urls.py ... From the modwsgi documentation: "Note that it is highly recommended that the WSGI application script file in this case NOT be placed within the existing DocumentRoot for your main Apache installation, or the particular site you are setting it up for. This is because if that directory is otherwise being used as a source of static files, the source code for your application might be able to be downloaded. You also should not use the home directory of a user account, as to do that would mean allowing Apache to serve up any files in that account. In this case any misconfiguration of Apache could end up exposing your whole account for downloading. It is thus recommended that a special directory be setup distinct from other directories and that the only thing in that directory be the WSGI application script file, and if … -
