Splitting Transaction across Multiple Views
I'm trying to figure out how to split a transaction across multiple views. This is what I have in mind: I have a view which creates a number of records (all packaged into a single transaction); The view presents some information on these changes and also a form which allows the user to either accept or reject; On the basis of the user's choice the transaction should either be committed or rolled back. The code that I have looks like this at present: @transaction.non_atomic_requests def record_results(request): if request.method=='POST': if "approve" in request.POST: transaction.commit() transaction.set_autocommit(True) if "reject" in request.POST: transaction.rollback() # # Turn AUTOCOMMIT back on again. # transaction.set_autocommit(True) # return render(request, 'updated.html') approve = ApproveForm() # Turn off AUTOCOMMIT. # transaction.set_autocommit(False) # Create records here. # # [...] context = { 'approve': approve, } return render(request, 'accept.html', context) Based on my understanding of the documentation, I thought that this would work. However, it does not do as I expected, so I suspect my understanding is flawed. If I comment out transaction.set_autocommit(False) then the data are committed, but immediately rather than after being approved. If transaction.set_autocommit(False) is included then no data are committed at all. Is the problem perhaps due to … -
How to get 'requests' object in custom function in django
I have created one library file where I have created one function suppose : def myfunc(param1): ---- --- do something ---- Now If I require requests object (to get details of user or something like that), How can I get requests object without passing parameter in my function.

Installing rpy2 with Docker is unable to find R path

Crispy forms layout different in local server and Ubuntu server
I am using crispy forms in my django forms and formset. It Worked as expected in the local server when run the same project in Ubuntu server its layout is different. For example, I am created a two column form using following code: class MemberForm(ModelForm): class Meta: model = Person exclude =('user',) def __init__(self, *args, **kwargs): super(MemberForm, self).__init__(*args, **kwargs) self.fields['name'].widget.attrs['placeholder'] = 'Your full name. 100 characters.' self.fields['tele_land'].label = 'Land phone' self.fields['tele_cell'].label = 'Cell phone' self.fields['passing_year'].label = 'Passing year' self.fields['passing_year'].help_text = 'According to your session year' self.helper = FormHelper() self.helper.form_method = 'POST' self.helper.form_tag = False self.helper.layout = Layout( Div( Div('name', 'name_in_bangla', 'nick_name', 'birth_date','blood_group','present_address','permanent_address','tele_land','tele_cell','photo','admission_session','degree_obtained','passing_year', 'category','is_active',css_class='col-md-5'), Div(css_class='col-xs-2'), Div('payment_number','bank_name','branch_name','profession', 'Designation', 'organization', 'official_address','office_phone', 'office_mobile','office_email','office_fax',' website','father_name','mother_name','is_married','national_id_no','passport_no','spouse_name','spouse_blood_group', css_class='col-md-5'), css_class='row-crispy' ), In localhost:8000 it gives two columns form but in Ubuntu server it gives one column form which is not desired. In another form it didn't show slug field which is shown by the localhost. Does anyone suggest me what will get rid of this behavior. -
Python Social Auth duplicating e-mails for different users
In my website it is possible to login through: username and password e-mail and password google auth 2 facebook Where I am using django user built in system and python social auth. The problem: Suppose I create the following account: username: losimonassi e-mail: lorenzosimonassi@gmail.com Then when I try to login with my gmail (lorenzosimonassi@gmail.com) python social auth creates another user with the same e-mail. So, when I try to login using my e-mail the auth system finds two similar e-mails which raises an error. I am trying to find a way that when the user try to login with gmail his e-mail is checked against the DB and if it already exists the process is stopped with a redirect and a alert message (I think it could be made through the middleware). But of course the checking against the DB should only check against other backends users and normal users, to avoid blocking his own login. I don't want to associate the accounts. settings.py SOCIAL_AUTH_PIPELINE = ( 'social.pipeline.social_auth.social_details', 'social.pipeline.social_auth.social_uid', 'social.pipeline.social_auth.auth_allowed', 'social.pipeline.social_auth.social_user', 'social.pipeline.user.get_username', 'social.pipeline.user.create_user', #'social.pipeline.social_auth.associate_user', #'social.pipeline.social_auth.load_extra_data', 'social.pipeline.user.user_details' ) enter image description here -

DRF: JSONField in serializers with TextField in models cause stringification
I am using python 2.7.11 A have a model let's say Game that has a TextField that's supposed to store json values. TextField was chosen because the database is shared with hibernate ORM that doesn't support postgres JSONb natively. Thus I have: models.py: @python_2_unicode_compatible class Game(models.Model): settings = models.TextField(default='{}') serializers.py: class GameSerializer(serializers.ModelSerializer): settings = serializers.JSONField() Is there a clean way to handle this, having valid json strings in the database and returning them as json objects through the API? -

migrations on django server 1.9 failing
I deployed my Django 1.9 project to Webfaction using FTP a few months ago.

Django - order many to many relation on id of intermediary model without using through
I am facing issue while sorting many to many field. I have many to many relationship on hobbies field. I want to keep the order user adds the hobbies. This can be done by sorting the records on intermediate model id. May people suggested to use through and add some field for ordering. But this creates problem while I create records using add function of related model. Is there any way to provide meta ordering to intermediary model so it can sort by id when I access data. My model is as - class User(AbstractBaseUser, PermissionsMixin): first_name = models.CharField(max_length=30) last_name = models.CharField(max_length=30) hobbies = models.ManyToManyField('UserHobby') class UserHobby(models.Model): hobby = models.CharField(max_length=100) -
Django Row Level Locking For Model Forms
I am using Python 3.5, Django 1.8 and PostgreSql 9.4. So I have one edit method where in get request I am rendering form and when user submit form it will get updated. Hers's the code def edit_case(request, case_id): case = get_object_or_404(Case, pk=case_id) if request.method == 'POST': data = request.POST.copy() form = CaseEditForm(data, instance=case) if form.is_valid(): res = form.save() return HttpResponseRedirect(reverse("case_list")) else: form = CaseEditForm(instance=case) variables = RequestContext(request, { "form": form, }) return render_to_response( 'sample/edit_case.html', variables, ) Now I want to add row level locking on it like if one user is updating something at the same time other will not be able update anything unless previous transaction succeeded Or if someone have any other better suggestions rather then using Pessimistic Locking. I know about select_for_update but don't have any idea how it will get implemented in case of form.save() Any help would be really appreciated -

Error: response = wrapped_callback(request, *callback_args, **callback_kwargs) File "/Users/Johnny/Desktop/pythondjango/django/user_dashboard/apps/login/views.py", line 18, in register regstatus = User.userManager.register(**request.POST) File "/Users/Johnny/Desktop/pythondjango/django/user_dashboard/apps/login/models.py", line 43, in register new_user.update(user_level='admin') AttributeError: 'User' object has no attribute 'update' code: views.py def register(request): regstatus = User.userManager.register(**request.POST) if regstatus[0]: request.session['user_id'] = regstatus[1] return redirect(reverse('dashboard:index')) else: for message in regstatus[1]: messages.warning(request, message) return redirect(reverse('login:index')) models.py: new_user = self.create(email=email, first_name=first_name, last_name=last_name, password=pw_hash) # Make first registered user an admin if new_user.id == 1: new_user.update(user_level='admin') return (True, new_user.id) These two snippets of code is where my errors are currently happening. Any help is greatly appreciated -
python django splitting models into separate files
I'm stumbling through learning python (3.5.2) and django (1.10.3). I have a project and that project has my first app. It is a member's area. I anticipate that this app will have a number of models and I like the idea of splitting the models out into their own files. I have seen an explanation of this here: https://code.djangoproject.com/wiki/CookBookSplitModelsToFiles -- MyApplication |-- __init__.py |-- settings.py |-- urls.py |-- wsgi.py -- Members |-- __init__.py |-- admin.py |-- apps.py |-- migrations | |-- __init__.py |-- models | |-- __init__.py | |-- address.py |-- tests.py |-- urls.py |-- views.py -- manage.py Members/models/__init__.py looks like from address import Address Members/models/address.py looks like from django.db import models class Address(models.Model): Member_ID = models.ForeignKey( settings.AUTH_USER_MODEL, on_delete=models.CASCADE ) Order = models.PositiveIntegerField() ... MyApplication/Settings.py has INSTALLED_APPS = [ 'Members.apps.MembersConfig', 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', ...

Why is the following Django URLConf regex not working?
URLConf urlpatterns = [ url(r'^(?P<slug>[\w./-]+)/$', page, name='page'), url(r'^$', page, name='homepage'), ] views.py def page(request, slug='index'): """Render the requested page if found.""" print slug file_name = '{}.html'.format(slug) page = get_page_or_404(file_name) context = { 'slug': slug, 'page': page, } return render(request, "page.html", context) You see that I'm printing the slug at the very first line of view. It prints the slug if I don't pass any parameter, however when I do pass a parameter in the URL, even if it is the default index, it shows Page Not Found.
