Licensing your software (run on web server?)
I've been working on a Python program that I'd like to sell. My business model would be temporal/functional licenses, i.e. standard, pro, full that could be monthly, anual or lifetime. I know it is practically impossible to protect your code, especially written in Python, from a good hacker. What I want is just a basic protection against mass copy (it probably won't be well distributed or looked for anyway) I've read a lot already but, honestly, there is so much information that I'm lost. By what I've read so far two models comes into mind: Make it a regular compiled software and use some kind of obsfucation on my code. Furthermore, implement some kind of cryptography to generate serial keys and build a server to test it against every time the software opens or periodically. Implement the software in a web server, which requires a login. The second is the one I'd like to know more, it seems more secure. I've read that there are some frameworks that can enable this like flask or django. Is it really possible to implement this with them? In addition, I don't want my server to get overloaded. For those web-implemented softwares, is it … -

How to create random (uid) file names for images uploaded with Django-CKEeditor?
I want to create random uid file names for images uploaded with the django-ckeditor/uploader. I've created utils.py in the same folder as settings.py: import uuid def get_name_uid(): ext = filename.split('.')[-1] filename = "%s.%s" % (uuid.uuid4(), ext) return filename I would like to add this "random" file name to settings.py: CKEDITOR_FILENAME_GENERATOR = get_name_uid() How can I do this? I am not sure how to get the filename that is uploaded in the editor. Should I pass the filename from settings.py to utils.py? Or is there a different way to do this? Their documentation says the following: ``CKEDITOR_UPLOAD_PATH = "uploads/"`` When using default file system storage, images will be uploaded to "uploads" folder in your MEDIA_ROOT and urls will be created against MEDIA_URL (/media/uploads/image.jpg). If you want be able for have control for filename generation, you have to add into settings yours custom filename generator. ``` # utils.py def get_filename(filename): return filename.upper() ``` ``` # settings.py CKEDITOR_FILENAME_GENERATOR = 'utils.get_filename' ``` CKEditor has been tested with django FileSystemStorage and S3BotoStorage. There are issues using S3Storage from django-storages. -
Performing migrations with multiple databases in Django
I have 2 databases in my Projects with multiple apps. All apps except for one are using default db, the other one has a separate db. After I ran makemigrations and ./manage.py migrate --database=separate_db_name I still have unapplied migration pending for default database. The question is how can I make this migration only visible for my separate app and not others(that use default db). Thanks Here is my router class S3DatabaseRouter(object): """ Determine how to route calls for s3web_upload_dev database """ def db_for_read(self, model, **hints): """ Attempts to read s3web_upload models to go to s3web_upload_dev """ if model._meta.app_label == 's3web_upload': return 's3web_upload_dev' return None def db_for_write(self, model, **hints): """ Attempts to write s3web_upload models to go to s3web_upload_dev """ if model._meta.app_label == 's3web_upload': return 's3web_upload_dev' return None def allow_migrate(self, db, app_label, model_name=None, **hints): """ Make sure the s3web_upload app only appears in the 's3web_upload_dev' database """ if app_label == 's3web_upload': return db == 's3web_upload_dev' return None -
Django : Migration of polymorphic models back to a single base class
Let's suppose I have a polymorphic model and I want to get rid of it. class AnswerBase(models.Model): question = models.ForeignKey(Question, related_name="answers") response = models.ForeignKey(Response, related_name="answers") class AnswerText(AnswerBase): body = models.TextField(blank=True, null=True) class AnswerInteger(AnswerBase): body = models.IntegerField(blank=True, null=True) When I want to get all the answers I can never access "body" or I need to try to get the instance of a sub-class by trial and error. # Query set of answerBase, no access to body AnswerBase.objects.all() question = Question.objects.get(pk=1) # Query set of answerBase, no access to body (even with django-polymorphic) question.answers.all() I don't want to use django-polymorphic because of performances, because it does not seem to work for foreignKey relation, and because I don't want my model to be too complicated. So I want this polymorphic architecture to become this simplified one : class Answer(models.Model): question = models.ForeignKey(Question, related_name="answers") response = models.ForeignKey(Response, related_name="answers") body = models.TextField(blank=True, null=True) The migrations cannot be created automatically, it would delete all older answers in the database. I've read the Schema Editor documentation but it does not seem there is a buildin to migrate a model to something that already exists. So I want to create my own operation to save the AnswerText and … -
Ignore inline model when saving
I've been looking on the documentation and stackoverflow/forums for a way to ignore the inline children of a model when I save it in django admin. I've been searching for a few days and I can't seem to find an answer. I have a normal tabularinline object: class UserOrdersAdmin(admin.TabularInline): model = Order classes = ['collapse'] And a normal User admin registration: class UserAdmin(BaseUserAdmin): inlines = (UserOrdersAdmin, UserSettingsAdmin) admin.site.unregister(User) admin.site.register(User, UserAdmin) What I simply want is when I press save within the User "change view", it will ignore the inline "UserOrderAdmin" which is inline to UserAdmin. -
Controlling model creation in Django and DRF
Consider the following Django model and DRF-based API: class Disk(models.Model): size = models.IntegerField(...) free_space = models.IntegerField(...) # ---- Serializers ---- # class DiskSerializer(serializers.ModelSerializer): class Meta: model = Disk fields = ('free_space', 'size') read_only_fields = ('size', ) class CreateDiskSerializer(models.Model): class Meta: model = Disk fields = ('size', ) # note, size only! # ---- View ---- # class DisksView(viewsets.ModelViewSet): ... def get_serializer(self): if self.request.method == 'POST': return CreateDiskSerializer else: return DiskSerializer I am trying to implement the idea of initializing the value of free_space field from size on model's creation. The naive approach would be overriding Disk.save() but that is something I would use at the very last resort. Another approach would be creating a custom model manager which overrides .create(), e.g.: class DiskManager(models.Manager): def create(self, **kwargs): if 'free_space' not in kwargs: try: kwargs['free_space'] = kwargs['size'] except KeyError: pass return super().create(**kwargs) Does it look acceptable to you? Is there a better solution? -

django.db.utils.IntegrityError: null value in column - but value is not null

Django Make Migration Error No Such Column
I have a pre-existing model that I am now trying to add an additional field too. It wasn't me that made the original field but I have been adding fields to other classes and making migrations fine. I want to add an additional image field to the class Event, there is already an image field on this class so I know it can handle image fields, I have tried changing the name around to see if that was a issue too. Here is the field I want to add: social_media_image = models.ImageField(null=True, blank=True, help_text='Hello World') This is the error I get when i'm trying to make my migration after adding that code to the model: django.db.utils.OperationalError: no such column: posts_event.social_media_image From my understanding of how migrations work there shouldn't be a column called this yet as I haven't made the migration yet that will add it to the DB. I have tried adding a default value to the field as well but with no luck. I have also tried completely removing the DB along with migration files and trying to recreate them. -

Display table rows according to keywords
I'm struggling with HTML, Javascript and the Django framework. I have a table. In one of the cases of this table, keywords are displayed. I'm doing bioinfo so it's stuff like "cellular_component" etc, but I'll call them item1, item2 and item3. See the code below : I display a list row for each "item". I would like, somewhere else on the page, to have three checkboxes (for item1, item2 and item3). When item1 is checked, only the rows in which item1 exists are displayed. Same for item2 and item3. I'm having a very hard time doing this, because the items are loaded in the table and the checkboxes are outside of it. Here is the code : <ul> <li> <input type="checkbox" > <label for="listcheck"><b>Item 1</b></label> </li> <li> <input type="checkbox" > <label for="listcheck"><b>Item 2</b></label> </li> <li> <input type="checkbox" > <label for="listcheck"><b>Item 3</b></label> </li> </ul> <table> <tr> <td>Foo</td> <td>Fighters</td> <td>Bar</td> <td> <!-- Only displayed if one of the items (see below) is checked in the list above --> <ul> {% for item in django_database %} <li> blahblah (actually a sub-list but whatever) </li> {% endfor %} </ul> </td> </table> I made a JSFiddle. -

On save edit FK model Django
The task that im trying to complete seems to be very simple and should be straight forward but i am having no look what so ever.

When the model is saved(partQuote) I want to update my other model in the same model.py doc called Job. Which is a Fk of the PartQuote model job = models.ForeignKey('jobs.Job', related_name='quote') The value of PartQuote.avg_quote should be saved in the job model instance as job.quote_price I have tried Django Signals but i dont really understand them that well and the django doc doesnt seem to help me. I have also tried to to it as a 'def' in the model. @receiver(post_save, sender=PartQuote) def f(sender, instance, created, **kwargs): instance.quoted_price = '10.00' instance.quoted_time = datetime.now() if self.avg_quote > 0: job = Job.objects.select_related() job.quoted_price = self.avg_quote Job.save() -

Using Django and Jquery
In addition to this post https://stackoverflow.com/a/17732956 I want to change the order of a list via drag'n'drop and save it afterwards in django backend. For test purposes and comprehension I've used following fiddle: http://jsfiddle.net/LvA2z/#&togetherjs=LvHpjIr7L0 and updated the action of the form with my own action. So, instead of script.php, I used action="{% url 'save_order' %}". In views my function looks like: def save_order(request): if (request.method == 'POST'): list = request.POST['listCSV'] print(list) Basically I want to change the order of list elements and save it afterwards with the result that after refreshing the page the saved order is given. However I do not know, how pass vars from jquery to django site. When I change the order, I have the sorted list in 'listCSV'. How do I pass this result to django site to save it in db?
