Django login not showing errors
I know there are multiple questions like this around, but none of them contain a clear answer. I am using the default authentication from Django, but have trouble displaying something like 'Your username/password combination is incorrect'. Is it possible to fix this without making a custom view function? My urls.py looks like this: url(r'^login/$', auth_views.login, {'template_name': 'login.html'}, name='mysite_login') Then my login.html has the following code: {% block content %} <section class="content"> <div class="container block"> <div class="row"> <div class="col-md-12"></div> <form action="{% url 'mysite_login' %}" class="form-control" method="post" accept-charset="utf-8"> {% csrf_token %} {% for field in form %} <p> {{ field.label_tag }}<br> {{ field|addcss:'form-control' }} {% if field.help_text %} <small style="color: grey">{{ field.help_text|safe }}</small> {% endif %} {% for error in field.errors %} <p style="color: red">{{ error }}</p> {% endfor %} </p> {% endfor %} <button type="submit" class="btn btn-dark">Login</button> <input class="form-control" type="hidden" name="next" value="{{ next }}"><br> </form> </div> </div> </div> </section> {% endblock %} So this all works, except for displaying the error messages. I've seen answers where you can write a custom view function and form to fix this, but I assume it should be also possible while using the build-in login functionality right? Thanks a lot. -
Can't install Django using pipenv for unknown reason (but can using pip)
I have no idea what is causing this issue, I have tried uninstalling and re-installing everything from scratch, and I still can't solve this after two days of trying. I could really use some expert help. Am I missing something fundamental here? On my desktop I am running Windows 10, on my laptop I am running Windows 7 (Professional, SP1). On desktop, I pipenv to install django==1.11, and pip freeze shows django==1.11 listed. On my laptop, use pipenv to install django==1.10, but pip freeze doesn't list django. When I check pipfile.lock, I see django listed in there. When I try to use django-admin startporject project, The term 'django-admin' is not recognized as the name of a cmdlet, function, script file, or operable program. Check th e spelling of the name, or if a path was included, verify that the path is correct and try again.

python django deploy vs ruby on rails capistrano deploy
i'm learning Ruby on Rails. And i wrote a small app. now i want to deploy it to my domain. i don't want to make it live under heroku. so i bought a host package from digitalOcean. i used a couple deployment tutor, but no luck. it doesn't show my homepage. i like Ruby on Rails so much. especially approaching to database. but deploying is very hard, if you don't want to pay for it a company like heroku. now, i'm thinking another choices. i love osx and i want to code there. because of this, i don't think to learn c# and .net. python is warm to me. so, is the deploying of python django easier than RoR deployment, like html/ccs/js or lamp sites? thank you all! -
Refresh page without reload. Wagtail
Where can i put ajax get data code in Wagtail? I have following page model: class ScreencastPage(Page): content_panels = Page.content_panels + [ InlinePanel( 'groupstage_screencast_relationship', label="Choose Teams", panels=None, max_num=2), ] parent_page_types = ['home.HomePage'] def matches(self): matches = [ n.match for n in self.groupstage_screencast_relationship.all() ] return matches And my template: {% for spiel in page.matches %} {% if forloop.first == forloop.last %} <div id="fullscreen"> <ul class="ulup"> <li class="logo_bg first_team">{% image spiel.team_1.team_logo width-400 class="logo" %}<p>{{spiel.team_1.title}}</p></li> <li class="first_team_score">{{ spiel.team_1_total_score }}</li> <li class="colons">:</li> <li class="second_team_score">{{ spiel.team_2_total_score }}</li> <li class="logo_bg second_team">{% image spiel.team_2.team_logo width-400 class="logo" %}<p>{{spiel.team_2.title}}</p></li> </ul> </div> {% endif %} {% endfor %} I started writing js. Just exaple: $(document).ready(function() { setInterval(function(){ $.ajax({ type: "GET", url: "/presentation", success: function(data) { $(".first_team_score").update(data.team_1_total_score); $(".second_team_score").update(data.team_2_total_score); } }) }, 10000); }); The idea is that the page will automatically update the value of <li class="first_team_score">{{ spiel.team_1_total_score }}</li> and <li class="second_team_score">{{ spiel.team_2_total_score }}</li> without reloading the page. I found here great example, but they using view.py We also need to write a new view.py or have wagtail some method for that? -
Override in the widget attributes the max_length set on the Model
In the Model I set the maxlength of the field: short_description = models.CharField(max_length=405) In the ModelForm in the widget attributes I set minlength an maxlength: widgets={ 'short_description': TextareaWidget(attrs={'minlength': 200, 'maxlength': 400}), .... } The issue in the HTML the minlegth is from the widget, but maxlength is still taken from the model(405 instead of 400). I want the widget attribute to overwrite the model attribute. -

When using ajax with django views, when should I use a method of GET and when should it be POST?
I'm able to accomplish the same task with either--I only need to make sure that if the ajax method is get, then my view needs to handle the get and if a POST, that the view handles a post. Given this, when do I use a GET and when do I use a POST? $.ajax({ method: "????", url: $endpoint, data: $buttonData, success: handleSuccess, error: handleError, }) class MyAjaxView(View): def ???(self, request, *args, **kwargs): -

Value error in Django because the view request.GET or request.POST can't catch values from javascript
I have a quiz app and there are lots of interactions between JavaScript in templates and django views. Normally, on decent enough internet connection and less traffic the code works as it is supposed to. But as soon as the internet is slow and traffic is high (ie. 20 or so people are taking a quiz at the same time) . Django views stop catching values sent from forms in template Here is an example: Template code <form action='{% url "QuestionsAndPapers:EvaluateTest" %}' method='post' id ='finishForm'> {%csrf_token%} <input type="text" name="timeTaken" value="" class='hidden' /> <button type="submit" id='testsub' value="{{te_id}}" class="btn btn-default text-center" name="testSub" onclick="formClick()" >Submit Test</button> </form> Django View: def evaluate_test(request): user = request.user me = Studs(user) if 'testSub' in request.POST: # get values of test id and total test time try: test_id = request.POST['testSub'] test_id = int(test_id) Now the problem is majority of times the template successfully returns {{te_id}} variable but when traffic is high and internet is slow evaluate_test function can't catch the {{te_id}} variable and it throws an error ValueError: invalid literal for int() with base 10: The problem is this error is not reproducible. -

Where should a Django homepage template and view exist in a large-scale project?
On a large-scale Django project, where should the homepage template and view exist within the project structure? In its own app (ex: homepage app)? Some other app (ex: accounts)? At the project-level putting the template in a "templates" directory and the view somewhere? Somewhere else? Is there a most frequent answer to this question? Definitions: Large-scale is defined as let's say 15 apps The homepage content is mostly static now, with plans to get more dynamic as the project evolves Assumption: project structure strategy is dependent on the size of the project. -

When posting to a Django form, are all fields posted?
I'm trying to write a test for a form to simulate the situation in which I'd like to update just one field. Here is the test: from django.test import TestCase from django.forms.models import model_to_dict class FamilyDemographicsUpdateTest(TestCase): def test_update_phone_types_with_fields_from_family_factory(self): # Create a family for which the employee uses an iPhone family = FamilyFactory(employee_phone_type=Family.IPHONE) url = reverse('dashboard:family', kwargs={'pk': family.id, 'tab': 'family-demographics'}) # TODO: This doesn't work because the FamilyFactory generates invalid form data. Fix that. data = model_to_dict(instance=family, fields=FamilyDemographicsForm.base_fields) form = FamilyDemographicsForm(data=data) after which I drop into the debugger with import ipdb; ipdb.set_trace(). It is here that I notice that the form has errors: ipdb> form.errors {'employee_email': ['This email is already taken.']} This can be traced back to the Family model on which the form is based.

Chrome Mobile does not display checkbox
My website's register page has two checkbox inputs located at the bottom. On every browser I have tested on, there has been no issue.

They do appear on my iPad and other Apple devices. Why are no checkbox inputs showing up on certain mobile devices? -

Linking up CSS (and static files in general) to html in Django
My html file isn't reading my css file - I've tried searching for all related questions on this issue, but still can't get the css file to be read. Here's what I have: settings.py BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__))) ... STATIC_URL = '/static/' STATICFILES_DIRS = ( os.path.join(BASE_DIR, "static"), ) Beginning of index.html {% load staticfiles %} <!DOCTYPE html> <html leng="en"> <head> <title>Test</title> <link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css"> <link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap- theme.min.css"> <link rel="stylesheet" href="{% static 'css/main.css' %}" /> </head> My "static" and "templates" folder are on the same level, and main.css is at static/css/main.css
