Mandatory slider in oTree/django
I want to use oTree as an alternative for conducting experiments. For this purpose I am looking for a possibility to include mandatory slider questions in forms, i. e. sliders you are required to move before you are able to proceed to the next question. As a start I tried to modify oTrees survey template to achieve a solution for future usage but wasn't able to integrate common approaches like a fieldtracker into the project. Here are two modified (yet currently after a number of unsuccessful try-outs not really functioning) versions of the models.py and views.py files which give a hint in which direction I want to go. # -*- coding: utf-8 -*- ## models.py # <standard imports> from __future__ import division from django.db import models from django_countries.fields import CountryField from model_utils import FieldTracker, from otree import widgets from otree.constants import BaseConstants from otree.db import models from otree.models import BaseSubsession, BaseGroup, BasePlayer class Constants(BaseConstants): name_in_url = 'survey' players_per_group = None num_rounds = 1 class Subsession(BaseSubsession): pass class Group(BaseGroup): pass class Player(BasePlayer): def set_payoff(self): """Calculate payoff, which is zero for the survey""" self.payoff = 0 q_country = CountryField( verbose_name='What is your country of citizenship?') q_age = IntegerFielder(verbose_name='What is your age?', min=13, … -
Django multi tenancy solution
This is a question, I'm asking after a thorough google & SO search. Is there any django app that can help me with multi tenancy in a single schema. Preferably the schema owner shall be able to create sub-user under her/himself as well. I have seen Django-tenant-schema and although its awesome, it uses schema, which I think might not be a good option, if there's more than 200,000 tenant owners. I have also seen django-simple-multitenant, however the solution uses "GNU Affero General Public License v3 which makes it somewhat impractical for anything that would not be free and open source applications." Any help would be appreciated. -
Language choice affects text overflow in html(bootstrap) (Django)
I'm using bootstrap to implement my post detail page. It works well and fit perfectly into tho format when using Korean. But, if I wrote english contents, it overflow the format.

Set wait_timeout on Django migration
I have a very long migration to run (creating index on large table), and I am getting (2013, 'Lost connection to MySQL server during query') So I tried to set the wait_timeout' via RunPython as below, which the settings has been tested on./manage shell`, but it doesn't seem to help in migration. I am wondering if I run it at the correct place? def set_long_connection(*args, **kwargs): seconds = 28800 cursor = connection.cursor() cursor.execute('SET wait_timeout = {}'.format(seconds)) class Migration(migrations.Migration): dependencies = [ ('feed', '0021_genericapi_extra_ds'), ] operations = [ migrations.RunPython(set_long_connection), migrations.AlterField( model_name='importjob', name='state', field=models.CharField(default=b'new', max_length=25, db_index=True), ), ] -
Django 1.9 + Photologue: no such column
I am using Django 1.9+ Photologue 3.x to build a photo gallery web app. When I am trying to add photo or gallery, it returns 'NO SUCH COLUMN EXCEPTION' Request Method: GET Request URL: http://127.0.0.1:8000/admin/photologue/gallery/ Django Version: 1.9.5 Exception Type: OperationalError Exception Value: no such column: photologue_gallery.slug Exception Location: //anaconda/lib/python2.7/site-packages/django/db/backends/sqlite3/base.py in execute, line 323 Python Executable: //anaconda/bin/python Python Version: 2.7.12 Then I have checked the model file and view file. In model.py @python_2_unicode_compatible class Gallery(models.Model): date_added = models.DateTimeField(_('date published'), default=now) title = models.CharField(_('title'), max_length=250, unique=True) slug = models.SlugField(_('title slug'), unique=True, max_length=250, help_text=_('A "slug" is a unique URL-friendly title for an object.')) description = models.TextField(_('description'), blank=True) is_public = models.BooleanField(_('is public'), default=True, help_text=_('Public galleries will be displayed ' 'in the default views.')) photos = SortedManyToManyField('photologue.Photo', related_name='galleries', verbose_name=_('photos'), blank=True) sites = models.ManyToManyField(Site, verbose_name=_(u'sites'), blank=True) objects = GalleryQuerySet.as_manager() It seems to be right. Since it is Django 1.9, no more syncdb or clear sql methods are available. And I tried migrate/makemigrations, sqlmigrates and none of them works. My idea is to rebuild the sql table but how to achieve this, or any other approaches to solve this issue? Thank you. -
Django isn't serving static files
I'm working with an existing (and previously functional) Django site. We recently upgraded from Django 1.8.13 to 1.10.

Django with Pycharm - PermissionError at /home/
I set up my first Django project in PyCharm this morning but seem to be receiving the following error whenever I intend to navigate to the /home/ view.

Creating ModelAdmin that has more then 1 view
I'm currently working on a project that has a more of a complex Admin page. Currently what I'm trying to accomplish is when a user adds a Report this report then checks a bunch of data and create a list of people within the area (Less then 10 km). So when they add a report when you click save its changes view to a view that lists all the people it found and their emails, you can then select the people you want to add and press another button which does more stuff. My code is as follows: admin.register(Report) class ReportAdmin(admin.ModelAdmin): change_form_template = 'admin/phone/index.html' # inlines = [SubjectInLine] def response_change(self, request, obj): """ Determines the HttpResponse for the change_view stage. """ opts = self.model._meta msg_dict = {'name': force_text(opts.verbose_name), 'obj': force_text(obj)} context = {} if "_email" in request.POST: msg = _('Report Saved - Now please select the store below you would like to notify.') % msg_dict self.message_user(request, msg, messages.SUCCESS) payload = {'address': str(obj.location.address1) + ' ' + str(obj.location.address2)} start = requests.get("https://maps.googleapis.com/maps/api/geocode/json", params=payload) start = start.json() start_long = start['results'][0]['geometry']['location']['lng'] start_lat = start['results'][0]['geometry']['location']['lat'] start_loc = (float(start_lat), float(start_long)) clients = Clients.objects.filter() context['report'] = obj in_ten = [] for c in clients: payload = {'address': … -
Django Form Not updating
I'm trying to update a form in Django. I have the following: models.py from django.db import models from django.core.urlresolvers import reverse class List(models.Model): def get_absolute_url(self): return reverse('view_list', args=[self.id]) # Create your models here. class Item(models.Model): text = models.TextField(default = '') list = models.ForeignKey(List, default = None) forms.py from django import forms from lists.models import Item EMPTY_ITEM_ERROR = "You can't have an empty list item" class ItemForm(forms.models.ModelForm): class Meta: model = Item fields = ('text',) widgets ={ 'text' : forms.fields.TextInput(attrs={ 'placeholder': 'Enter a to-do item', 'class': 'form-control input-lg', }), } error_messages = { 'text' : { 'required': EMPTY_ITEM_ERROR } } I'm not seeing any changes in the forms.py now that it has been loaded. What I mean is, the page displays the form find, but if I attempt to change, for example, the placeholder value:: 'placeholder': 'Enter a to-do item OR DON'T!', The input box doesn't show any changes once the page loads. Is there a manage.py command I need to run? Or some other migration? -

Django Static image File Failed to load resource

Why supervisor doesn't start after `restart` comand?

Django: "referenced before assignment" but only for some variables
I'm writing a small app in Django and I'm keeping the state saved in a few variables I declare out of the methods in views.py. Here is the important part of this file: from app.playerlist import fullList auc_unsold = fullList[:] auc_teams = [] auc_in_progress = [] auc_current_turn = -1 print(auc_in_progress) def auc_action(request): data = json.loads(request.GET["data"]) # ... elif data[0] == "start": random.shuffle(auc_teams) print(auc_unsold) print(auc_in_progress) auc_in_progress = [None, 0, None] print(auc_in_progress) The auc_unsold and auc_teams variables work fine; the auc_in_progress variable is not seen by this method, though, giving the error in the title. If I take out the print statement and let this code assign a value to it, the exception will be thrown somewhere else in the code as soon as I use that variable again. I have tried making another variable and this new one seems to suffer from this problem as well. What is happening? -

Django template a tag link to another page for another column in the same view
I'm learning Django, and trying to create some practice by extending the polls app from the tutorial. Tried to find an answer but ended up with nothing. Please help!

Then I created a template and an url that would show me a list of the database names (the 1st column of my view), and a hyperlink which I intend to link me to another page showing me the DBCreationDate.

Django: display object's another field from template tag?

Object permissions with read only access for anonymous users in Django Rest Framework
The problem I am using Django REST Framework - and so far I have been using the DjangoObjectPermissions permissions class. I use django-rules to determine which users have permissions for objects. However, this permissions class seems to deny read access to anonymous users. I need to find the best way to allow read-only access to all users (authenticated or not). For additions, modifications and deletions - the object permissions should be applied as normal. What is the best approach to solving this problem? Django does not seem to provide a can_view permission by default. Perhaps this will involve manually adding a can_view permission for each model. Or maybe it's better to somehow implement a DjangoObjectPermissionsOrAnonReadOnly permissions class? -

Unable to find/edit ~/.bash_profile in windows machine
I'm following this tutorial (http://www.marinamele.com/taskbuster-django-tutorial/install-and-configure-mysql-for-django#install-mysql) to begin working with MySQL on my django projects.

Im doing this the following way. def tag_content(obj): for tag in Tag.objects.all(): print tag obj.tags.add(tag) obj.is_tagged = True obj.save() class Tag(models.Model): name = models.CharField(max_length=255) class Content(models.Model): title = models.CharField(max_length=255) is_tagged = models.BooleanField(default=False) tags = models.ManyToManyField(Tag, blank=True) def save(self, *args, **kwargs): super(Content, self).save(*args, **kwargs) @receiver(post_save, sender = Content) def update_m2m_relationships_on_save(sender, **kwargs): if not kwargs['instance'].is_tagged: tag_content(kwargs['instance']) The tag_content function runs, however, the m2m relationships are not established. Im using Django 1.9.8 btw. This makes no sense. What am I missing? Moreover, if I do something like tag_content(content_instance) in shell, then the tags are set, so the function is ok. I guess the problem is in the receiver. Any help?
