Checking duplicate email when editing user profile in Django
I am trying to check the duplicate email while I am logged in as a user and editing my own profile. But when the email entered is the email of current logged in user and I do not want to update my current email then also I am getting a duplicate email error message. accounts/forms.py class UserProfileForm(forms.ModelForm): class Meta: model = models.Profile fields = ("organisation", "phone_number") first_name = forms.CharField(max_length=30) last_name = forms.CharField(max_length=30) phone_number = PhoneNumberField(label=_("Phone (Please state your country code eg. +44)")) organisation = forms.CharField(max_length=30) email = forms.EmailField() def __init__(self, *args, **kwargs): super(UserProfileForm, self).__init__(*args, **kwargs) self.initial['first_name'] = self.instance.user.first_name self.initial['last_name'] = self.instance.user.last_name self.initial['email'] = self.instance.user.email helper = FormHelper() helper.layout = Layout( Div( Field("first_name", wrapper_class="col-sm-6"), Field("last_name", wrapper_class="col-sm-6"), css_class = "row" ), Div( Field("organisation", wrapper_class="col-sm-6"), Field("email", wrapper_class="col-sm-6"), css_class = "row" ), Div( Field("phone_number", wrapper_class="col-sm-6"), css_class = "row" ), ) def clean_email(self): email = self.cleaned_data.get('email') if email and User.objects.filter(email=email).exists(): raise forms.ValidationError(u'Please use a different email address.') return email def save(self, commit=True, *args, **kwargs): self.instance.user.first_name = self.cleaned_data['first_name'] self.instance.user.last_name = self.cleaned_data['last_name'] self.instance.user.email = self.cleaned_data['email'] self.instance.user.save() return super(UserProfileForm, self).save(commit, *args, **kwargs) How can I check if the entered email is a new email and if it is new email then check duplicate function else ignore email field … -
Deploying Django projects with conda
Environment management in Python projects is critical and is commonly done with venv or virtualenv. However, I am interested in deploying a Django project with conda. The basic setup looks like the one here. Django is served using gunicorn which is controlled with supervisor. That conda does not use folders as environments basically means that there is no isolated directory where the Django project could live (hope I got this right). This post has a nice description of how to deploy a Python project with conda in general. For using this with supervisor I was thinking if activating a specific conda environment with installed dependencies in supervisor would suffice to create the needed results. I assume this supervisor config might look something like this: [program:djangoapp] command = .activate django-env; python gunicorn djangoapp.wsgi:application -b 127.0.0.1:8000 directory = /path/to/djangoapp ... The supervisor docs say that supervisor will search the supervisord’s environment $PATH for the executable, if it's provided without an absolute path. Does this mean that the absolute path of the conda environment needs to be used here? Long story short: Is anyone using conda for this and is it even usable the way I like to do it and if yes: … -

How can I display a view based on a database value
I want to use one view (URL) for 2 conditions. In my application, "owners" create daily plans for routes they manage, and update the plans/results throughout the day. class DailyRoute(models.Model): owner = models.ForeignKey(Owner) route = models.ForeignKey(Route) driver = models.ForeignKey(Driver) stops = models.PositiveSmallIntegerField(default=0, ... on_duty_hours = models.TimeField(default=datetime.time... date = models.Datefield(... finalized = models.Boolean(... Essentially, there are 3 database conditions, 2 of which I'm trying to use for a view: No database row for the date/route. This means that the owner hasn't created a plan for the day. (e.g. if DailyRoute.objects.filter(stage = 0).count() == 0:...) A database row for the date/route with finalized = False. This means that a plan has been created for the day for the date/route pair and can be edited. (e.g. DailyRoute.objects.filter(stage = 0).count() >0 ) A database row for the date/route with finalized = True. This means that a plan/updates for the day are complete and no further edits are allowed. (e.g. if DailyRoute.objects.filter(stage = 1).count() > 0:...) As a daily activity, I want the user to go to a URL (e.g. /account/daily) and be presented with one of these views: a) If no owner routes (point 1 above), provide an "Add" button to add a row … -

Can this be done with Scrapy or something else?
Compared to 99% of you on this site, I am a newbie when it comes to programming & other technical issues. Luckily I have a son with a CS degree who is pretty talented. Unfortunately, he is extremely busy so when I ask him to do something for me I have to have my ducks in a row to make him efficient. Scrapy looks like a tool that he could use to do something for me. I just wanted this communities’ thoughts on whether I’m sending him in the right direction. I promise that there will be no newbie level follow-up questions from me once I have determined that this is the right tool for him to use for what I want to accomplish. I’m looking for a tool that can constantly and quickly scan part of a website for newly added pages. Ideally, I need it to find the new page within 1-2 seconds after it is added. Before normally using this website I am required to logon to gain access (so it needs to be able to handle that). I only want this tool to scan the part of the website where the web address starts with an … -

Setting up a virtual environment for python3 using virtualenv on Ubuntu
I want to learn Django so for that, as per the instructions on the website, you need to create a virtual environment. I've heard enough horror stories about people corrupting their OS cause they didn't set up the virtual environments properly so it's safe to say I'm sufficiently paranoid. I've created a separate folder/directory VirtualE at located at Academics/CS/VirtualENV and I want to create all my virtual environments there. As per the website, the following command should be used - virtualenv --python=`which python3` ~/.virtualenvs/djangodev I'm not sure what exactly I should write in place of the single quotes (the which python3 part). I wrote the following - virtualenv --python=3.5.2 ~/Academics/CS/VirtualENV/DjangoDev It says The path 3.5.2 (from --python=3.5.2) does not exist Where exactly am I going wrong? -

limiting the number of displayed instances of a model in Django Admin
I have a model which over timer will have several thousand to tens of thousands of instances. Each of those is unique. In the Django Admin interface I can see all the instances and access them ect. Is there a way for me to limit the number of instances I can see to lets say 20 or 50 sorted in whichever order and I can look through them like pages? I ask because loading all several thousand instances will likely clog up my server. So how do I limit it?

invalid literal for int() with base 10: 'choosen_room_1_id'
I was trying to access part of the model self attributes, however after migrations this error showed up. The model works perfectly fine before I ran makemigrations and migrate. After reading through the value error page, I notice that the value error was cause by the model trying to access it's own foreign key(choosen_room_1) under a property function. models.py def getTotalPricing(self): total_price = 0 amount = dict() if self.choosen_room_1 is not None: The choosen_room_1 attribute was defined as below: models.py choosen_room_1 = models.ForeignKey(ChoosenRoom, default=None, related_name="room_type_1", null=True) Some things I have tried so far are: remove old migrations file check if id field exist in the table using sqlite terminal, and it does exist force choosen_room_1 to_field as 'id' or 'choosenroom_id', same error still exist Using django admin interface I am sure the choosenroom wasn't null and was able to reassign it with a new foreign key item. Accessing choosen_room_1 using manage.py shell will give me the same error. After reading through some of the stackoverflow issues, my guess was somehow foreignkey was expecting the unique id key with integer type, however something went wrong during query process?

Slow Image Loading with Lightbox Plugin and Amazon S3
I am hosting a Django app which displays images inside a gallery-view called lightbox (https://github.com/ashleydw/lightbox). Every Image is loaded via a presigned url from Amazon S3. The problem is that the image only starts loading as soon as it is viewed in the gallery, not any sooner. For some users this then takes a couple seconds to load. I am not to sure whether S3 is the bottleneck, but is there any method to force preloading of images that are currently "invisible"? Even preloading the next picture in the gallery would suffice I think. I am aware that Cloudfront enhances loading times from S3 as well, but is currently not an option. -

Loaddata return error "Key (user_id)=(2) already exists."
i have data in Sqllite3, but i want to use PostgreSQL so i did dumpdata then loaddata it says this error: psycopg2.IntegrityError: duplicate key value violates unique constraint "uyelik_ders_bilgileri_uye_id_23796fd8_uniq" DETAIL: Key (user_id)=(2) already exists. i think it is about my models.py, because i created extended user profile with these codes: class ders_bilgileri(models.Model): user=models.OneToOneField(User,on_delete=models.CASCADE) dersler = models.TextField(max_length=500,blank=True,default="bos") facebook_adresi=models.URLField(max_length=1000,blank=True) facebook_mesaj_gonderilsin=models.BooleanField(default=True) twitter_mention_atilsin=models.BooleanField(default=True) twitter_adresi = models.CharField(max_length=1000,blank=True) facebook_idsi=models.CharField(max_length=100,blank=True,default="yok") pushed_id=models.CharField(max_length=100,blank=True) def __str__(self): return str(self.user) @receiver(post_save, sender=User) def create_user_profile(sender, instance, created, **kwargs): if created: ders_bilgileri.objects.create(user=instance) I tried then get_or_create but nothing changes, what is the problem you think? -
Can I login in with Facebook as an unregistered user? (Django, all-auth)
I'm building my Django RESTful Framework to retrieve and post data for Mobile. I'm using djang-rest-auth (which is just all-auth with RESTful functionality; more info: http://django-rest-auth.readthedocs.io/en/latest/). Question: Social Auth in all-auth is not clear to me. Can you finish this use case? Use Case: Unregistered User User Login with Facebook on Mobile Mobile gets facebook token from Facebook SDK Mobile sends token to our DRF Backend server URL which is '/rest-auth/facebook' And what happens? Can you complete this Use Case? <- This is my question My guesses: all-auth automatically create new user for facebook user token and return new token? Then, it saves created user to settings.AUTH_USER_MODEL? Or...? I found 'social account' in Django admin. Are we saving User in this account..? -
how to setup django database accessed from 3 apps
I have 3 apps in a project. What I want to do are 2 things. (1) I want to setup each apps to access same database(Read & Write). I have no idea that I have to have same models.py each of my apps. If so, how can I migrate database. I tried it, but one app which was used to do migrate command success database access. But other 2 apps couldn't access database. And I tried to make simbolic link of models.py and migrations directory to each apps directories. But it didn't work too. (2) I want to use django authentication system to each of my apps. App1 (For Enduser) - (email, password) App2 (For Service provider) - (ID, password) App3 (For System Administrator) - (ID (different from App2), password) I can use django user authentication system from 1 app. But I want to make authentication system to 3 apps from different urls. App1 is a webview based app that use django via rest framework. App2 and App3 are web application (different url and port). Can I make it on using django? Would you give me some advice please? -
Django - creaing a custom model admin form field, passing the model instance to set a read only attribute
I know you can set readonly_fields in a model's admin.py but I am trying to make a field read only dependent upon it's (saved) value in the database. I can create a custom field Class, but am unable to pass the value of the model instance so I can achieve the above. Eg class MytypeField(models.CharField): def __init__(self,*args,**kwargs): PAGE_LAYOUT_CHOICES = ( ('column1','One Column'), ('column2','Two Columns') ) kwargs['max_length'] = 7 kwargs['choices'] = PAGE_LAYOUT_CHOICES kwargs['default'] = 'column1' super(MytypeField,self).__init__(*args,**kwargs) And in the model layout = MytypeField() Is there a way to do this in admin.py rather than in the model itself? I can't pass the model instance to this custom class, and I'm sure that's not the way to do it anyway! Many thanks!
