How to clean up input data in a Django view to avoid CSRF?
Lets say, in a view, I use input data to create an instance of a Model in my Django project. def create_post(request, message): post = Post.objects.create(message=message) post.save() Now, the problem is, the 'message' is coming from sources which may be unsavory, that is, a plugin that makes AJAX requests to my API. If it was a django form, I could have just used {% csrf_token %} and cleared the issue, but, I want to do this in my view. How do I do this? Note, please don't suggest adding csrf protection in my Javscript code, because that will not work for my case. Thanks! -
Django - how to work in live/dev environments and upgrade live?
I was wondering how i should work in Live/Dev environments in django and how to update the app. Currently I just edit the live version and if i break it i fix it. but the app is reaching a point where its not feasible to do this anymore. So i was wondering how best to do things? do i keep a copy locally on my machine and edit that then upload files? or should i package it and upgrade it once it has no bugs? (if the latter how do i create an upgrade package? Thanks for any advice -

im trying to set the ChoiceField length in my django form, I used the below: from django.forms import TextInput, Textarea, ChoiceField class SiteAdmin(admin.ModelAdmin): formfield_overrides = { models.CharField: {'widget': TextInput(attrs={'size':'25'})}, models.ChoiceField: {'widget': TextInput(attrs={'size':'25'})}, models.GenericIPAddressField: {'widget': TextInput(attrs={'size':'25'})}, } ... and then got the error: File "/var/www/infternal/sites/admin.py", line 18, in SiteAdmin models.ChoiceField: {'widget': TextInput(attrs={'size':'25'})}, AttributeError: 'module' object has no attribute 'ChoiceField' Does anyone know what i need to alter to change the select/dropdown length?

Django, Javascript: Can't upload image from other PCs
Here is a strange one. Although, when I login from my PC I can upload an image (using my client's credentials), when others login from their PCs they can't upload images. I am not talking about application hosted on my PC. I am talking about the one that is on the production server. So, we both use the exact same code. It is important to note that I get no error or warning message in my log files. The form I am using is something like this: <form method="post" action="{% url 'add_recipe' %}" enctype="multipart/form-data"> {% csrf_token %} <div id="file_upload-drop" class="uk-file-upload" style="background-image: url('/media/{{ recipe.featured }}'); background-repeat: no-repeat; background-position: center;"> <p class="uk-text">Drag an image</p> <p class="uk-text-muted uk-text-small uk-margin-small-bottom">ή</p> <a class="uk-form-file md-btn">Please, select an image to upload<input id="file_upload-select" name="image" type="file"></a> </div> <div id="file_upload-progressbar" class="uk-progress uk-hidden"> <div class="uk-progress-bar" style="width:0">0%</div> </div> as you can see there is a progress bar just underneath the image upload. and the views.py is like this: if request.method == "POST": image = request.FILES.get("image") and this is the models.py from sorl.thumbnail import ImageField class FoodRecipe(models.Model): featured = ImageField(upload_to='recipe', default=None, blank=True) The progress bar has a javascript code like this: var progressbar = $("#file_upload-progressbar"), bar = progressbar.find('.uk-progress-bar'), settings = { action: '/media/recipe', … -
django formset: it is always trying to create when the form is updated
I have been Googling around for this question for quite long. And sadly no luck. Indeed I found questions like SO question and SO question. I would say I found myself having a very similar question to the first one. However, I do not understand the discussions under that question. So first of all, to make it clear, I did not even get formset.is_valid() to return True--that is the problem. There are indeed uniqueness check but my edit should be able to pass that check in the database level. And here comes my code: ### models.py class DataAccess(models.Model): user = models.ForeignKey(User, models.CASCADE) project_data = models.ForeignKey(ProjectData, models.CASCADE) role = models.CharField( max_length=2, choices=ROLES, default='N' ) created_at = models.DateTimeField(auto_now=True) updated_at = models.DateTimeField(auto_now=True) class Meta: unique_together = (('user', 'project_data', 'role'),) # query from project data should happen more index_together = [['project_data', 'user', 'role']] def __str__(self): return '{}&{}&{}'.format(self.user, self.project_data, self.role) def save(self, *args, **kwargs): curr = datetime.now() if not self.created_at: self.created_at = curr self.updated_at = curr return super(DataAccess, self).save(*args, **kwargs) class DataSyncPath(models.Model): server = models.ForeignKey(Server, models.CASCADE) project_data = models.ForeignKey(ProjectData, models.CASCADE) path = models.CharField(max_length=128) created_at = models.DateTimeField(auto_now=True) updated_at = models.DateTimeField(auto_now=True) class Meta: unique_together = (('server', 'project_data',),) index_together = [['project_data', 'server']] def __str__(self): return '{}&{}'.format(self.server, self.project_data) def … -

What is the Correct Django Model Relationship
Im a beginner in django and its modeling structure. And i would like to seek answer from anyone. I have a model Animal and Herd Each herd has a multiple animals and an animal belongs to a herd.

Because i am confuse with the djangorestframework serializer relations of Album and Track model relationship.

django: call overridden model method from django template
I have overrode (overrided?) the get_FOO_display() method of django model class (see: doc reference) to return some different choice field mapping. But, on calling this function from the django template as {{ model_object.get_FOO_display }} calls the base class method instead of the new overridden method. I read the source code django/db/models/base.py and it seems like this is not some regular method rather, it is created dynamically for the model fields. (let me know if am getting it wrong) Is there a way I can resolve to the overridden method from the template ? See this code to get the essence of my issue: class UserStatus(models.Model): invite_status = models.CharField(max_length=15, choices=USER_STATUS, default='new') # Overridden method def get_invite_status_display(self): return dict(USER_STATUS_DISPLAY).get(self.invite_status) Yes, I need to display different content than the choices dict and no, I cannot keep my to-be-displayed content in the choice dict in the first place. Let me know if there is any possible way to make this template call work. Thanks. -
Django 1.8. Formset. Implement check field for delete image
I have a formset for update with image file and clear field. If clear is True I need to delete image from model. How can I get current model in formset and update it? What is the best way to do it?

Deserializing SlugRelatedField on ForeignKey with Django Rest Framework

Django custom test runner remove some of the default test argument
I write a custom test runner in Django to add custom argument '--headless', but the side effect is i can not use some of the default argument. I am using Django 1.9.11.

How can I embed django code in html?(pagination)

I tried something like: <nav> <div class="text-center"> <ul class="pagination pagination-centered"> {% for i in range(1, photos.practical.index) %} <li><a href="{% url 'practicals:detail' photos.practical.id i-1 %}" aria-label="previous">&laquo;</a></li> <li><a href="{% url 'practicals:detail' photos.practical.id i %}">2</a></li> <li><a href="{% url 'practicals:detail' photos.practical.id i+1 %}" aria-label="next">&raquo</a></li> {% endfor %} </ul></div> </nav> It seems that we cannot use parenthesis() inside {% %}, so range function cannot be used and (i-1),(i+1) cannot be used either. So how can I use pagination the better way? -

Django template blocks
