How to print django model data with template forloop?
Here I have template for tags, and i want print them all by forloop but with the tag id. e.g: {% for tag in tags %} <div class="row"> <div class="col-md-3 col-sm-6 col-xs-12"> <div class="photo-rounded-fluffs"> <a href="#"> <img class="img-responsive" src="{% static 'assets/img/fluffs/1.jpg'%}" alt="Image"> <h1 class="text-center">{{tag.title}}</h1>#Here i want print tag with tag id 1 </a> </div> </div> <div class="col-md-3 col-sm-6 col-xs-12"> <div class="photo-rounded-fluffs"> <a href="#"> <img class="img-responsive" src="{% static 'assets/img/fluffs/2.jpg'%}" alt="Image"> <h1 class="text-center">{{tag.title}}</h1> #here i want to print tag with id 2 </a> </div> </div> </div> {% endfor%} Right now the both tag title are same because same tag is repeating twice.

Django - allauth: How to remove allauth login and signup urls
I am trying to use Django-allauth for some password resetting functionalities, however, I am trying to disable login/signup with django-allauth. So far I have not been able to find a way to either redirect users to my custom signup and login or completely disable those URLs. I was wondering if there is a workaround on how I can remove those URLs? My current approach was to add all the URLs manually without those, but that is causing an error with my social-login links. Currently, I have added the following to my URLs: url(r"^accounts/logout/$", allauth_views.logout, name="account_logout"), url(r"^accounts/password/change/$", allauth_views.password_change,name="account_change_password"), url(r"^accounts/password/set/$", allauth_views.password_set, name="account_set_password"), url(r"^accounts/inactive/$", allauth_views.account_inactive, name="account_inactive"), # E-mail url(r"^accounts/email/$", allauth_views.email, name="account_email"), url(r"^accounts/confirm-email/$", allauth_views.email_verification_sent,name="account_email_verification_sent"), url(r"^accounts/confirm-email/(?P<key>[-:\w]+)/$", allauth_views.confirm_email,name="account_confirm_email"), # password reset url(r"^accounts/password/reset/$", allauth_views.password_reset,name="account_reset_password"), url(r"^accounts/password/reset/done/$", allauth_views.password_reset_done,name="account_reset_password_done"), url(r"^accounts/password/reset/key/(?P<uidb36>[0-9A-Za-z]+)-(?P<key>.+)/$",allauth_views.password_reset_from_key,name="account_reset_password_from_key"), url(r"^accounts/password/reset/key/done/$", allauth_views.password_reset_from_key_done,name="account_reset_password_from_key_done"), # social account path('socialaccount/login/cancelled/', allauth_socialviews.login_cancelled,name='socialaccount_login_cancelled'), path('socialaccount/login/error/', allauth_socialviews.login_error,name='socialaccount_login_error'), path('socialaccount/signup/', allauth_socialviews.signup, name='socialaccount_signup'), path('socialaccount/connections/', allauth_socialviews.connections, name='socialaccount_connections'), However, since I have a Google social login I get an error: Reverse for 'google_login' not found. 'google_login' is not a valid view function or pattern name How can I implement this without causing any errors? -
Cant get objects while testing Django 1.8.4
I have a test class, extending TestCase. I have a setUp() method in it, in which I do some preparations for tests in this suite: I create objects in db (using .objects.create(), so its pretty similar to what we have in Django docs). I create an instance of Client, so that I can perform some .post() and .get() requests. So, I perform a request on address specified in urlpatterns. In this endpoint to which I perform request, underneath the hood some query takes place. And the problem is IT CANNOT FIND THE OBJECTS CREATED IN setUp() In debugger, I see that endpoint is resolved correctly, request comes as it should, but when objects.get() or objects.filter() is called (with proper arguments), it cannot find the entry in testing db. -

I'm implementing a list of clients. I want to give to the user the possibility of importing new clients thought a csv file.

Django, struggling to make a form

How to search for the mode of a field in a one to many relationship in django's ORM?

Django does not seem to have functionality to implement this easily. So let's say we have three restaurants, Anny's, Domino and Verspucie. Anny's has different 8 dishes of which 2 dishes are labeled as being Hot, all other dishes are labeled as Mild, since the owner wants to be able to have a varied menu for children Domino has 9 different dishes of which 5 dishes are labeled as being Hot, 2 as being Super Hot and 2 as being mild. Verspucie has 10 different dishes of which 8 are labeled as being Super Hot, one 1 labeled as Mild and 1 is labeled as Hot.

Django Rest Framework: Rest-auth email verification - Server Error 500

How to add the result of a custom query to the Django Admin Site change_form template?
My web application manages hospitalizations and specialist examinations. Some of these exams may have been performed during a hospitalization, but I have no connection between the hospitalizations and the specialist exams. When the user modifies the data of an exam, I would like him to see at the bottom of the page all the admissions started before the exam and finished after the exam, because one of them could be the admissions where the exam was taken. How can I show the result of the query described above at the bottom of the "change_form" template of the Django Admin Site? Thanks in advance. -

How to run a function in Django after a certain time passed by
Having the model of Station with the below fields: class Station(models.Model): is_available = models.BooleanField(default=True) unavailable_until = models.DateTimeField(null=True,blank=True) I can define until when my station is unavailable by giving a DateTime value , so when that action happens the is_available value turns to False. I want to turn the is_available value to True every time the unavailable_until value passed by(comparing with the current time based on the timezone). How can I achieve an automation like this? Imagine that I have a lot of Station records which belong to station owners which can update the availability (assign new unavailable_until value if passed by) whenever they want. I think the logic could be something like: def turn_availability_to_true(station): if (station.unavailable_until < current_time): station.is_available = True But how can I implement a function like this to be called by its own when the unavailable_until value passed by? -
