Is there a fast way to allow list / create / modify / delete model data in a django project?
Basically I want to have the django admin functions in a normal app without having to write separate class or function based views for each function like list / create / modify / delete, etc. Just want to confirm if there is a fast way? -
Django Template getting apparent catchall error: "AssertionError at / No exception message supplied"
I'm getting an error I believe to be secondary damage, or else a catchall error when the real error has not been pinpointed. (N.B. One search result for the error message said to make sure your tags have correct syntax; no {# ... %}. I double-checked, and I didn't notice any failures of properly nesting, opening, and closing tags. The code that Django's 500 page is highlighting is: 5 <table> 6 {% for pet in pets %} 7 {% if not pet.should_hide %} 8 <tr> 9 <th valign="top"> 10 <a href="/pet/{{ pet.slugline }}" 11 ><img src="{{ pet.main_image }}" /></a> 12 </th> 13 <td valign="top"> 14 <h2> 15 {% if pet.slugline %} 16 <a href="/pet/{{ pet.slugline }}"> 17 {% endif pet.slugline %} 18 {% if pet.name %} 19 {{ pet.name }} 20 {% else %} 21 Anonymous 22 {% endif %} 23 {% if pet.breed_or_type %} 24 - <span class="breed-or-type" 25 >{{ pet.breed_or_type }}</span> The line that is labeled as causing the problem is 15, {% if pet.slugline %}.

django makemigrations fails after removing a class
I have a model like this: class States(Enum): first = 'one' second = 'two' choices = ( (States.first, 'First'), ... ) class MyModel(models.Model): state = FSMField(choices=choices) and another model like: class MyOtherModel(models.Model): new_state = CharField(choices=myapp.choices) For various reasons, I removed the States Enum and replaced it with a bunch of constants like: FIRST = 'one' I then migrated my database, and it all went fine. But when I later run ./manage.py makemigrations, I get an `AttributeError: module 'myapp.models' has no attribute 'States'. The traceback ends like this: File "myapp/migrations/0038_xxx.py", line 12, in <module> class Migration(migrations.Migration): File "myapp/migrations/0038_xxx.py", line 36, in Migration ('new_state', models.SmallIntegerField(choices=[(myapp.models.States('one'), 'First'), (myapp.models.States('two'), 'Second')])), AttributeError: module 'myapp.models' has no attribute 'States' but if I paste the States definition back into my models file, then makemigrations runs fine. How am I supposed to remove this code if old migrations still require it? I have a bunch of migrations that follow this 0038, most of which have already been applied to the production database. -

django-admin-bootstrapped conficts with django-autocomplete-light with error: $("[title]").tooltip() is not a function
I'm setting up a django site using django-autocomplete-light (v3); however, when I add django-admin-bootstrapped, the following error occurs: $('[title]').tooltip(); tooltip is not a function. I installed 'dal' and 'dal_select2' before 'django-admin-bootstrapped' and 'django.contrib.admin' in settings.py as follow: 'dal', 'dal_select2', 'django_admin_bootstrapped', 'django.contrib.admin', It appears to me that, django-autocomplete-light has its own jquery and somehow overrides the django-admin original jquery. It might be a jquery loading issue, because when I run collectstatic, I can clearly see a new jquery.min.js and a jquery.init.js added by django-autocomplete-light. But this is not an issue at all until I add django-admin-bootstrapped which breaks the page loading with that error. In Chrome Dev Tools Network tab, I can see both django admin and django-autocomplete-light jquery being loaded and that appears to be the problem. How to solve this issue ? How to control which scripts get included by vendors in collecstatic ? Do I have to manually delete or edit generated static files by collecstatic ?(which might not work when deploying to heroku for instance) Or is there a better way to control what collectstatic process and create some post processing function to solve this conflict ? -
Combining two queries from different application/models to display them on a single overview page
I have only recently started working with Django and was wondering how one would go around to combine two queries from different application/models and display them in a given overview page. I will display some non-functional pseudo-code below to illustrate what I am trying to do: Index.html Note that I added two seperate context_object_names here just to illustrate what I am trying to do (latest_news and latest_enzyme) {% extends 'base.html' %} {% block body %} <div id="docs-content"> <div class="section" id="s-module-django.db.models.fields"> <div class="page-header text-primary"> <h3 class="info-header-blue-publication-small">Overview</h3> </div> <div> <h3 class="info-header-blue-publication-tiny">Latest news:</h3> </div> {% if latest_news %} {{ latest_news.news_text }} {% else %} <p>No recent news.</p> {% endif %} <div> <h3 class="info-header-blue-publication-tiny">Latest enzyme:</h3> </div> {% if latest_enzyme %} <ul> <li><a href="{% url 'gts:detail' latest_enzyme.id %}">{{ latest_enzyme.barcode }}</a></li> </ul> {% else %} <p>No enzymes are available.</p> {% endif %} </div> </div> {% endblock %} Views.py Note that this contains some commented lines that illustrate the method that I was trying but did not get working, as well as two seperate get_querysets to illustrate my intent. from django.shortcuts import render from django.http import HttpResponse from django.views import generic from gts.models import Enzymes from news.models import News # Create your views here. class IndexView(generic.ListView): template_name … -

ElasticSearch to Django APIView - Results limited
I'm trying to proxy my ElasticSearch connection via Django so I can filter results and use authentification. I want the django URL to behave as connecting directly to Elastic Search (:9200). The below code connects, and gives the same results as "http://localhost:9200/_search" However, all other requests it makes return the same result. I get no errors. When I connect to ES directly (:9200), it always does OPTIONS & POST. When I connect to ES via Django, it always does POST, rarely OPTIONS services.py def elastic_result(id, request): url = 'http://localhost:9200/_search' r = requests.post('http://localhost:9200/_search', params=request.data) items = r.json() return Response(items) views.py from services import elastic_result class ElasticView(APIView): permission_classes=[] def post(self, request): item_list = elastic_result(id, request) return item_list pass url router.register(r'elastic/_search', ElasticView, base_name='Elastic') -

Django/NGINX/Ubuntu: Media files - [Errno 13] Permission denied
I've deployed my web on Digital Ocean VPS - Ubuntu 14.04. I have a ImageField in one of my models which I choose in Django admin (browse pc and upload the image). The problem is that this image can't be saved into /media/categories/. It's raising: [Errno 13] Permission denied: '/home/django/project/media/categories/television_d3q3EM0.png' I thought that it is, because Nginx hasn't write privileges to /media/ directory so I run these commands: sudo chown -R www-data /media/ which didn't help sudo chown -R django /media/ which didn't help neither I'm a newbie in Linux rights so I can't figure out what am I doing wrong. Media folder is in /project/ directory (where the manage.py is). Here are permissions of the /media/ folder. Owner has rights so I don't know why sudo chown -R www-data /media/ didn't work. -
Django static files go missing when debug is set to False
I just set up a small web application in a production environment that uses static css files. This works fine when debug is set to True but as soon as debug is set to False, the css files go missing and I only see the html page as ugly as can be. Any thoughts on how I can fix this? Thanks! -
Call Django view function from AngularJS
I want to get the list of my existing users when a page loads. Everything works when getting the information from the Angular script, but it will be stored serverside. I've made a Django view: def getUsers(request): response = {} response['user'] = { 'username': 'guy1', 'password': 'guy1', 'fName': 'John', 'lName': 'Smith', 'email': 'guy1@host.com', 'role': 'Employee', 'theme': 'default' } return JsonResponse(response) Currently, I just pass my user there, later it will be filled with information from a postgre DB. I think I've set the url correct: urlpatterns = [ url(r'^$', views.index, name='index'), url(r'^', views.dashboard, name='dashboard'), url(r'getUsers/', views.getUsers), ] And finally, I call the view from Angular when the page loads: $http.get("getUsers") .then(function(output) { $scope.testUser = output; console.log($scope.testUser); }); When I run everything, the browser console comes up with incorrect output. Any ideas as to what I've done wrong? Thanks. -

How to limit objects an admin (without superuser) can interact with?
I am trying to build a platform and I thought using Djangos administrive user interface was simpler and faster than writing an own. The issue I have is that I don't want all admins to be able to see all objects, just the ones they are affiliated with. I use my own created model called Organisation which basically is the affiliation. I were reading this article: http://reinout.vanrees.org/weblog/2011/09/30/django-admin-filtering.html but it seems old and outdated. Because I copied the example and came up with this: class QuizAdmin(admin.ModelAdmin): form = QuizAdminForm list_display = ('title', 'category', ) list_filter = ('category',) search_fields = ('description', 'category', ) def queryset(self, request): """Limit quizzes to those that belong to the correct organisation.""" qs = super(QuizAdmin, self).queryset(request) org = Organisation.objects.get(user=request.user) if request.user.is_superuser: return qs return qs.filter(org=org) But it seems like the queryset method never runs. Is there another easy way to filter out the objects an admin user can interact with? Thanks in advance for your sage advice and better wisdom. -

django wsgi app settings
I'm trying to run my django application using the built in wsgi. My directory is structured as follows: /project/ -/project/ - settings.py - wsgi.py - urls.py -/app/ Here is the provided wsgi.py file, which I've modified a bit. import os from django.core.wsgi import get_wsgi_application # used to be crowdlabel.settings os.environ.setdefault("DJANGO_SETTINGS_MODULE", "project.settings") application = get_wsgi_application() if __name__ == "__main__": application.run() When running python project/wsgi.py , I get an error that the module project can't be found. To solve this, I change os.environ.setdefault("DJANGO_SETTINGS_MODULE", "settings"). Doing this then gives me a new error in the get_wsgi_application() function, ModuleNotFoundError: No module named 'app'. I am beyond confused so if anyone with experience could suggest what I'm doing wrong it would be greatly appreciated. As a note, the app runs fine on the test server. -
CRM for Django - New developments
I've been looking into CRM packages for Django recently. As far as I can see the, main options (koalix and Django-CRM) seem outdated, with unclear status and a lack of python 3 support. I am wodering why this is the case, since I consider Django to be among the best and most powerful tools to base a CRM application on. Therefore, I have invested some time in developing a simple and customizable CRM application for Django (django-leancrm) and I am currently thinking about open-sourcing it. Since maintaining this package will bind future resources, I am unsure if the effort is worth it. So, am I overlooking something? Is anybody aware of other CRM packages for Django currently still maintained or is there anything new currently under development? Thanks for your answers and opinions! -
How make uploaded image to fit in bootstrap div in django

How to use Django RegexValidator with AJAX?
I have a form with an input field. I validate this field with RegexValidator and it works. Also, I use django-crispy-forms. class EncryptionForm(forms.Form): shift = forms.IntegerField( label='Shift', max_value=26, min_value=1, initial=1) input_text = forms.CharField( label='Input', widget=forms.Textarea, validators=[ RegexValidator( r"^[A-Za-z\s0-9-!#$%&'*+/=?^_`{}|~.,<>():;@\\\[\]\"]*$", message='Please use english language!', code='invalid_language' ), ] ) I made this form work trough AJAX. validation for shift still works(max_value, min_value). And validation for input_text doesn't work(RegexValidator). I need to create new validation rule in jQuery or I can pass my RegexValidator(or just error) through AJAX? function submitForm(){ $('#id_intake_form').on('submit', function(){ var link = $(this); var action = $(this).find('#id_action').val(); var shift = $(this).find('#id_shift').val(); var input_text = $(this).find('#id_input_text').val(); $.ajax({ 'url': link.attr('action'), 'type': 'POST', 'dataType': 'json', 'data': { 'action': action, 'shift': shift, 'input_text': input_text, 'csrfmiddlewaretoken': $('input[name="csrfmiddlewaretoken"]').val() }, 'success': function(data, status, xhr){ if(status != 'success'){ alert('Error on server.

Please try again later.'); return false; } }); return false; }); } Now when input isn't valid I have "Error on server" alert from AJAX error. -
Django. Advanced search implementation.
I'm looking for relaively simple way to implement advanced search functionality in Django. I need to generate following form and obtain search results using this form. Form schema: general text input (text passed here will be used to search through all specified fields of given model + possible relationships) several checkboxes (those will be used to pick which fields will be included in search [all specified fields by default]) several pairs of inputs (those pairs will responsible for declare the scope used to limit search result e.g: date from -/- to, or mass from -/- to) I've checked several apps (django-watson, django-filters, django-haystack) and tried to bulid my own implementation but I didn't find proper (and simple) solution. Any ideas how could I manage this task? I'll be grateful of any answers!
