In this class based view....assuming that queryset = self.objects.get(user_assigned=pk) has a value...I would like it to return it back to AccountModify so def get_object(self, queryset=None): can take it and return it. Right now def get_object() is not receiving it and returning blank queryset class AccountCreateOrModify(object): model = Employee form_class = AccountForm template_name = 'bot_data/account_modify.html' success_url = reverse_lazy('home') class AccountModify(LoginRequiredMixin, AccountCreateOrModify, UpdateView): def dispatch(self, request, *args, **kwargs): try: pk = self.request.user.pk queryset = self.objects.get(user_assigned=pk) except Employee.DoesNotExist: return redirect('account_add') if request.method.lower() in self.http_method_names: handler = getattr(self, request.method.lower(), self.http_method_not_allowed) else: handler = self.http_method_not_allowed return handler(request, queryset) def get_object(self, queryset=None): return queryset

If I create a CustomUser model which inherits from django.contrib.auth.models.User, like so: in models.py class CustomUser(django.contrib.auth.models.User): customfield = TextField() ... Should I still be able to use django.contrib.auth.{authenticate, login, logout} in the normal way? Do I have to make some additional configuration change? I know these methods only work on User objects, but technically my CustomUser is-a User. Currently, authenticate(username=u, password=p) is always returning None, even with valid credentials.

In my database, I have a Customer table defined in my database that all other tables are foreign keyed on. class Customer(models.Model): ... class TableA(models.Model): Customer = models.ForeignKey(Customer) ... class TableB(models.Model): Customer = models.ForeignKey(Customer) ... I'm trying to implement a database router that determines the database to connect to based on the primary key of the Customer table. For instance, ids in the range 1 - 100 will connect to Database A, ids in the range 101 - 200 will connect to Database B. I've read through the Django documentation on routers but I'm unsure if what I'm asking is possible. I'm essentially attempting to implement application level sharding of the database. Is this possible in Django?

Based on my previous question and feedback I received I have redesigned my Models and need some feedback before I run the "syncdb". My concerns are mostly ForeignKeys and the one ManyToManyField in the Restaurant table. Should also the ManyTomany field have the through='' value and what the value should be? Any feedback is appreciated! Models class Restaurant(models.Model): id = models.AutoField(primary_key=True, db_column='id') name = models.CharField(max_length=50L, db_column='name', blank=True) address = models.CharField(max_length=100L, blank=True) city_id = models.ForeignKey('City', related_name="restaurant_city") location_id = models.ForeignKey('Location', related_name="restaurant_location") hood_id = models.ForeignKey('Hood', null=True, blank=True, related_name="restaurant_hood") listingrole_id = models.ForeignKey('Listingrole', related_name="restaurant_listingrole") cuisine_types = models.ManyToManyField('Cuisinetype', null=True, blank=True, related_name="restaurant_cuisinetype") class Meta: db_table = 'restaurant' class City(models.Model): id = models.AutoField(primary_key=True, db_column='id') name = models.CharField(max_length=50L, db_column='city') state = models.CharField(max_length=50L, db_column='state', blank=True, null=True) class Meta: db_table = 'city' class Cuisinetype(models.Model): id = models.AutoField(primary_key=True, db_column='id') name = models.CharField(max_length=50L, db_column='cuisine', blank=True) # Field name made lowercase. class Meta: db_table = 'cuisinetype' class Location(models.Model): id = models.AutoField(primary_key=True, db_column='id') name = models.CharField(max_length=50L, db_column='location', blank=False, null=False) city = models.ForeignKey('City', related_name="location_city") class Meta: db_table = 'location' class Hood(models.Model): id = models.AutoField(primary_key=True, db_column='id') name = models.CharField(max_length=50L, db_column='hood') city = models.ForeignKey('City', related_name='hood_city') location = models.ForeignKey('Location', related_name='hood_location') class Meta: db_table = 'hood' class Listingrole(models.Model): id = models.AutoField(primary_key=True, db_column='id') name = models.CharField(max_length=50L, db_column='listingrole', blank=True) # Field name ...

I am very new to Django, so please bear with me if my question seems naive. How do I change values of a form based on a condition before the form loads? For example, if there is a form checkbox field called "Admin", and the user is an admin, I would like to know how I could have that checkbox field checked before the form loads. Do I add this logic to the view calling the form or do I add this to the form class? I am using Django 1.4.

I have got example simple Django + Mongoengine app from here https://github.com/sneawo/django_mongo_test This is simple blog app that store posts in Mongodb. Now i want admin interface, for this i found django-mongonaut http://django-mongonaut.readthedocs.org/en/latest/installation.html I passed all install instructions, but still when trying to access localhost:8000/mongonaut/ i see You do not have permissions to access this content. What is the worst - there is no any login form. This is my mongoadmin.py # myapp/mongoadmin.py http://django-mongonaut.readthedocs.org/en/latest/configuration.html # Import the MongoAdmin base class from mongonaut.sites import MongoAdmin # Import your custom models from blog.models import Post, Tag # Instantiate the MongoAdmin class # Then attach the mongoadmin to your model Post.mongoadmin = MongoAdmin() Tag.mongoadmin = MongoAdmin() I am new to django, this is my last chance to work with Django + Mongodb, i took several days going through multiple tutorials i found in net - tried django-nonrel with mongodb-engine, and other options. I am really frustrated, because i cannot find full working tutorials, some of them works, but with unexpected errors. Also i tried Quokka http://quokkaproject.org/but it is alpha and some pages don't work too...

I think I might be missing something key here.... I have a view that renders a formset to a template SurveyFormset = formset_factory(SurveyForm, extra=0) survey_formset = SurveyFormset(initial=data) And the form on that is submitted with ajax... $(document).ready( function() { var form = $('#surveyset'); form.submit( function(event) { event.preventDefault(); $.ajax( { type: "POST", url: form.attr( 'action' ), data: form.serialize(), success: function( response ) { console.log( response ); } }); }); }); the form action points to the following view... def save_survey_set(request): if request.is_ajax(): return HttpResponse('hello babes') # Redirect to a 'success' page Normally I would just do survey_formset = SurveyFormset(request.POST) But I don't have that to look at, I already made the formset with the other view. I just have post data from form serialized... So what do I do?

I have django models defined as class Event(models.Model): event_id=models.IntegerField(primary_key=True) OS_CHOICE=(('Win 2003','windows 2003'), ('Win 2008','Windows 2008'), ('Win XP','Windows XP'), ('Win VISTA','Win VISTA'), ('Win 2007','Windows 2007'), ) windows=models.CharField(max_length=10,choices=OS_CHOICE,default='Win 2003') def __unicode__(self): return " %s, event_id :%s" \ % (self.windows, self.event_id) class Meta: db_table= 'event' verbose_name_plural='events' class Eventgroups(models.Model): event=models.ManyToManyField(Event) group_name=models.CharField(max_length=100) def __unicode__(self): return "%s, %s" \ % (self.group_name, self.event) class Meta: db_table= 'eventgroup' verbose_name_plural='eventgroups' I want to write a django view that will anable a user browse to a csv file and click on import to upload/import the selected csv file to the models defined above(consider the M2M field in you answer please). Will anyone please give some guidance on this? An example based on my models will be much appreciated. Regards

I have a form where all the fields are valid. I now want to send an email if the form is valid but if sending the email fails, I want to generate an error message for the user. What is the proper way to do this? Should I redirect the user to a new page with the error or re-render the form as invalid. views.py from myapp.forms import ContactForm from django.views.generic.edit import FormView class ContactView(FormView): template_name = 'contact.html' form_class = ContactForm success_url = '/thanks/' def form_valid(self, form): # This method is called when valid form data has been POSTed. # It should return an HttpResponse. form.send_email() return super(ContactView, self).form_valid(form) In this example if form.send_emai() returns an error message, whats the best way to return that message back to the user? My send_email() function returns an error if the user has already sent the same email before, or if the recipient has opted out of receiving emails. I want to relay these messages back to the user.

I have csv files that i want to import to django models. I want a feature whereby i can drag and drop the csv file and it automatically imports this csv to a django models(like we do in dropbox). Anyone with an insight on this please. An example will be much appreciated. Regards, Josh

I have two Django models, Team and Player, where Player has a many-to-one relationship with Team: class Team(models.Model): name = models.CharField(max_length=20) class Player(models.Model): name = models.CharField(max_length=20) team = models.ForeignKey(Team) I have created a Team object, and saved it in the SQL database: my_team = Team(name = 'Django_FC') my_team.save() Now, I want to create a Player object, my_player, whose team is the my_team object that I just created. But I am outside the scope of where I created my_team, so I must load it from the database in order to assign it to my_player's team. I have therefore tried the following: the_team = Team.objects.filter(name = 'Django_FC') my_player = Player(name = 'Mr_Python', team = the_team) However, I get the following ValueError exception: Cannot assign "[<Team: Django_FC>]": "Player.team" must be a "Team" instance. Please can somebody explain what I am doing wrong? Thank you.

Trying to save a form with AJAX. This is what I have so far... <form action="/save_survey_set/" method="POST" id="surveyset">{% csrf_token %} {{ survey_formset.management_form|crispy }} {% for form in survey_formset.forms %} <div id="survey-{{ forloop.counter }}" class='content'> {% crispy form %} </div> {% endfor %} <input id='save_set' type="submit" value="Submit" class='button' /> </form> <script> $(document).ready( function() { var form = $('#surveyset'); form.submit( function() { $.ajax( { type: "POST", url: form.attr( 'action' ), data: form.serialize(), success: function( response ) { console.log( response ); } }); }); }); </script> And the view... def save_survey_set(request): if request.is_ajax(): return HttpResponse('hello babes') # Redirect to a 'success' page And... The error: The view reports.views.save_survey_set didn't return an HttpResponse object. Why is it not recognizing the request as AJAX?

I started using Haystack, and everything seems to be working, the index was created, etc.. The urls on my website are all of the type '/something/someparam/someotherparam' and I use ajax calls to get every piece together. Now, I would like for haystack to receive the query in such a format. This is what I've been doing so far #Nothing special here, default stuff class ProjectSearchForm(SearchForm): def search(self): # First, store the SearchQuerySet received from other processing. sqs = super(ProjectSearchForm, self).search() if not self.is_valid(): return self.no_query_found() return sqs #Same here, nothing much, except that I'm trying to grab the query from a view parameter class ProjectsSearchView(SearchView): template = 'projects/_project_archive.html' searchqueryset = SearchQuerySet().models(Project) form_class = ProjectSearchForm def get_query(self): return self.kwargs['query'] In my urls.py I'm trying to do something like this: url( regex=r'search/(?P<query>[-\w\d\+]+)$', view=ProjectsSearchView.as_view(), ), So, I was hoping that "ProjectSearchView" would catch the regex parameter 'query' and pass it as search query to the form in order to perform the search.. But this isn't working (basically because Haystack's views are not like django views, and I'm not sure they can get parameters from the regex. I tried making the view a subclass of ListView (or simple view), but it didn't work.

I have 2 views...one to modify a database object with UpdateView. The other view uses CreateView in case the object doesn't exist. I am using a redirect to CreateView if the query find that the object does not exist. However, I get 'HttpResponseRedirect' object has no attribute '_meta' and can not figure out why. class AccountCreateOrModify(): model = Employee form_class = AccountForm template_name = 'bot_data/account_modify.html' success_url = reverse_lazy('home') class AccountModify(LoginRequiredMixin, AccountCreateOrModify, UpdateView): def get_object(self, queryset=None): try: pk = self.request.user.pk query_set = self.model.objects.get(user_assigned=pk) return query_set except Employee.DoesNotExist: return redirect('account_add/') class AccountCreateRecord(LoginRequiredMixin, AccountCreateOrModify, CreateView): print "hi"

I'm developing a simple web application in Django, and I wanted to start a Scrapy spider from an admin action.

I suppose this must be possible judging by this post but I can't seem to work out the syntax. I need to get the blog object with the picture field via the author foreign key. Is this possible with get_object_or_404, and if so how? #models.py class Blog(models.Model): author = models.ForeignKey(MyUser) #author class MyUser(AbstractUser): picture = models.ImageField() blog = get_object_or_404(Blog, pk=blog_id)

I'm trying to enqueue a basic job in redis using django_rq, a python library for queueing jobs and processing them in the background with workers, but the simple call throws a: AttributeError: 'dict' object has no attribute '__module__' I've traced down the issue to this line in the rq library: if not isinstance(f, string_types) and f.__module__ == '__main__': raise ValueError('Functions from the __main__ module cannot be processed ' 'by workers.') I'm passing a function in as f so I dont understand how it can throw an attribute error on a dict. Any ideas on whats going wrong?

I have two lists of Django model objects, which I want to display on a template. list1 is a one-dimensional array, and list1 is a two-dimensional array. In the template, I want to loop through each element in list1, display its value, and then display all the values of the corresponding element in list2. For example, if list1 = ['Andrew', 'Ben,' 'Charles'] and list2 = [[3, 4, 8], [12, 9], [10, 0, 5, 1]], then I want to display: - Andrew - 3 - 4 - 8 - Ben - 12 - 9 - Charles - 10 - 0 - 5 - 1 My question is, in my template, how can I loop through list1 and then access the corresponding element of list2? The following code is what I have so far: <ul> {% for name in list1 %} <li>{{ name }} <ul> {% for A %} <li>{{ B }}</li> {% endfor %} </ul> </li> {% endfor %} </ul> What should I write in place of A and B?

I initialize a dict and add objects into it like this, so that at the end of day, i can render data to template data = {} data['one'] = "1" data['two'] = "2" data['three'] = "3" ... ... but, is there a one-line solution for this?

Im trying to write a model Manager to get all entries that is published, and start_date is in the past of now. The strange thing is if I set the date to a value in the past, everything works, but if I set the date 1 minute in the future, the object does not show, even if I wait more than 1 minute to test. If I do nothing but restart the server, the entry is shown. But I can't restart the server everytime I publish an entry. Anyone see what could be wrong with this code? Or could this be done differently? from django.utils import timezone now = timezone.now() def entries_published(queryset): """Return only the entries published""" return queryset.filter( models.Q(start_publication__lte=now) | \ models.Q(start_publication=None), models.Q(end_publication__gt=now) | \ models.Q(end_publication=None), status=PUBLISHED) class EntryPublishedManager(models.Manager): """Manager to retrieve published entries""" def get_queryset(self): """Return published entries""" return entries_published( super(EntryPublishedManager, self).get_queryset()) class Entry(models.Model): title = models.CharField(max_length=255) slug = models.SlugField(max_length=255) categories = models.ManyToManyField(Category, related_name='entries', blank=True, null=True) creation_date = models.DateTimeField(auto_now_add=True) start_publication = models.DateTimeField(blank=True, null=True, help_text="Date and time the entry should be visible") end_publication = models.DateTimeField(blank=True, null=True, help_text="Date and time the entry should be removed from the site") status = models.IntegerField(choices=STATUS_CHOICES, default=DRAFT) objects = models.Manager() published = EntryPublishedManager() My view ...
