I want to add a iCal to my Djano site
I am building a website for a client for his vacation homes. He currently uses multiple vacation home sites to list his homes. Each site links to his iCalendar and if someone books a date it shows across all sites. What I want to know is the best approach to adding a iCal to my Django framework and linking it to a form so users can message him about available dates. Appreciate any direction. -
Exceptions in django stop the flow?
in my view I am executing this piece of code: try: activeterm = LeaseTerm.objects.get(lease=lease, is_active = True) except LeaseTenant.DoesNotExist: activeterm = None And I expected there will be no value in LeaseTerm I will get exception but I am getting an error: LeaseTerm matching query does not exist.

RelatedObjectDoesNotExist - in clean function of the model

Can not import models.UUIDField and other Django methods in deployment
I'm deploying my Django 1.9.8 project on a debian server. I'm repeatedly facing errors because django can not import some methods and packages. For example first it could not import slugify by following expression: from django.utils.text import slugify but then I checked it in django shell, and I saw no errors. After changing that to: from django.utils import text I could use text.slugify in my views. Now I'm facing new issue, which tells me: "'module' object has no attribute 'UUIDField'" but again in shell I can define a variable using models.UUIDField with no errors. Any idea why this is happening? -
Using MariaDB with Django 1.10 and Python 3.5
I want to migrate my database from SQLite to MariaDB. Running Ubuntu 14.04, Django 1.10 and Python 3.5. Digital Ocean has a guide, but it silent assumes one is using Python 2.x, not 3.x. They use the default mySQL connector, MySQLdb. This does not work for python 3.x.

Is it possible to create steam trading bot in Python?
I'm building website in Django where i will definitely need to use a trading bot, unfortunately, i couldn't find any good libraries that would do a job. ( Smiley's SteamAPI didn't have that feature ). Now i am trying to build my custom one, and i still don't understand how could i possibly do some things, is it even possible to be done in Python? I did find some code, but did not understand it quite well. The normal explanation is big, so code example is way more easily explainable: # Note: This code is example, it doesn't work. import mechanize import cookielib import steamapi from multiprocessing import Process from time import sleep br = mechanize.Browser() cj = cookielib.CookieJar() br.set_cookiejar(cj) def Listener(): while True: sleep(15) br.open("https://steamcommunity.com/tradeoffer/") if "If new offer appears": return "Bot accepts it" # ( I will make protections later ) def Sender(): while True: sleep(10) if "User bought item": # ( I don't need help on this line. ) items = ["something", "something2"] return "Make a trade using SteamID or Profile name" + items # ( So basically i need to make trade offer and send users items). if __name__ = '__main__': p1 = Process(target=Listener) p2 = … -
Django log requests with status 200 to syslog

Django: add filtering sidebar to a change list admin view
I have a back-end module showing a quite long items listing that looks like this: ID Label Type 1 Label 1 Type A 2 Label 2 Type B 3 Label 3 Type A 4 Label 4 Type D 5 Label 5 Type C 6 Label 6 Type D 7 Label 7 Type C What I want to do is quite simple: I want to add a "filter by" sidebox listing all available types, for example Available Types Type A Type B Type C Type D If clicked they should enable filtering by single type. For example, if I click on "Type A" only items belonging to that type will be shown. Sidebar's HTML should look like this <ul> <li><a href="?type=11">Type A</a></li> <li><a href="?type=12">Type B</a></li> <li><a href="?type=13">Type C</a></li> <li><a href="?type=14">Type D</a></li> </ul> How can I implement that? I'm quite confused right now... Thanx a lot! -
How to apply / unapply a Django migration programmatically?

How do I reverse a named Django URL to the urlpattern that defines it?
My Django app contains a couple of external references, e.g. to the application's blog, which is not part of the Django codebase and is hosted on a different subdomain. So far, links to these were spread all around the source code as direct absolute URLs. Now I was wondering if there was a way to use Django's excellent URL routing system for these external URLs as well. I thought I could define them like this: url(r'^permalink/blog/$', RedirectView.as_view(url='https://blog.example.com'), name='blog'), Then I could just reference them as {% url 'blog' %} in my templates. That works. Now I was wondering if there was a way to resolve these directly to the 'final' URL with a special (self-defined) template tag, so that they appear as https://blog.example.com to the user, as opposed to /permalink/blog/ (to the browser) or https://app.example.com/permalink/blog/ (to the user). I do already have a self-defined {% absolute_url %} template tag, which I use in templates that require absolute URLs, like transactional email. However, I couldn't find a way to reverse a named URL (like external:blog) to its urlpattern as opposed to its final relative URL. To do this myself, it seems like I'd have to duplicate all the code from URLNode.render(), … -
Django: file field validation in model
I have a model containing file field. I want to restrict it to pdf files. I have written clean method in model because I want to check for admin and shell level model creation also. But it is not working in model clean method. However form clean method is working. class mymodel(models.Model): myfile = models.FileField() def clean(): mime = magic.from_buffer(self.myfile.read(), mime=True) print mime if not mime == 'application/pdf': raise ValidationError('File must be a PDF document') class myform(forms.ModelForm): class Meta: model = mymodel fields = '__all__' def clean_myfile(self): file = self.cleaned_data.get('myfile') mime = magic.from_buffer(file.read(), mime=True) print mime if not mime == 'application/pdf': raise forms.ValidationError('File must be a PDF document') else: return file If I upload pdf, mime in form clean method is correctly validating (printing 'application/pdf'). But model clean method is not validating. It is printing mime as 'application/x-empty'. Where am I doing wrong ? -

Django: custom input + select search into admin items listing module
I am working to an admin items listing + search module and I need to apply a more complex search pattern than the one provided in basic templates. This is how my listing view looks like: ID Label Type 1 Label 1 Type A 2 Label 2 Type B 3 Label 3 Type A 4 Label 4 Type B This is how my search div should look like (#searchbar2 options are the result of a filter but I'm just simplifying) <label for="searchbar">Label:</label> <input type="text" size="40" name="{{ search_var }}" value="{{ cl.query }}" id="searchbar" autofocus /> <label for="searchbar2">Type:</label> <select name="{{ search_var2 }}" id="searchbar2"> <option value="A">Type A</option> <option value="B">Type B</option> </select> <input type="submit" value="{% trans 'Search' %}" /> What should I do do archieve that? Looks like I cannot obtain this by using default templates and search_fields array and so I'm quite confused on how to proceed. At first I'd say that I must implement my own search_form.html override but how can I make admin/change_list.html load my override? After that, How I'm supposed to handle submitted values into the admin.py class of the module? Thanx in advance for your precious help -

Django: If model field has editable=False does it matter if blank is set to True or False?
From Django: As currently implemented, setting auto_now or auto_now_add to True will cause the field to have editable=False and blank=True set. Field.editable If False, the field will not be displayed in the admin or any other ModelForm. They are also skipped during model validation. Default is True. Field.blank If True, the field is allowed to be blank. Default is False.? Note that this is different than null. null is purely database-related, whereas blank is validation-related. If a field has blank=True, form validation will allow entry of an empty value. If a field has blank=False, the field will be required. Am I correct when I say blank=True won't be validated? Does it matter in this case if it was set to blank=False?
