Django: TypeError - argument of type 'QuerySet' is not iterable
So this error is very cryptic, how can it be that a Queryset object, even if empty, is not iterable? This is the rare error I'm seeing: TypeError: argument of type 'QuerySet' is not iterable And this is the code producing this error: artist_object = Artist.objects.get(id=id) artist_release_groups = artist_object.release_groups.all() if rg not in artist_release_groups: # this is the line where the error is happening artist_object.release_groups.add(rg) I don't know if this is relevant, but this is happening in a celery task and the error is being reported in Sentry (an exception reporting service). -
Django Password Reset - HTML encoded characters not displaying properly in e-mails
I am trying to get my password reset function to send e-mails with Spanish characters, like so: views.py def reset_password(email, from_email, template='registration/password_reset_email.html'): form = PasswordResetForm({'email':email}) return form.save(from_email=from_email, email_template_name=template) password_reset_email.html Para iniciar el cambio de contraseña hacer click aquí E-mails sent to @yahoo.com show up the way I want them to: Para iniciar el cambio de contraseña hacer click aquí E-mails sent to @gmail.com show up like this: Para iniciar el cambio de contraseña hacer click aquí I tried passing in html_email_template_name to the form.save() function and mucking with the content_type, but it still doesn't work. Anyone know what could be going on here? Thanks. -
TemplateDoesNotExist with Django-Fobi
Alright, so I'm not that new to programming, but I still have newbie problems. I'm using Python 2.7 , Django 1.8 I installed django-fobi around 2 days ago and have been pulling my hair since. Things are better now, but one error refuses to resolve: TemplateDoesNotExist at /fobi/forms/create/ the template is: bootstrap3/create_form_entry.html although the loader does find it: project_name/fobi/contrib/themes/bootstrap3/templates/bootstrap3/create_form_entry.html (File exists) However, the other templates of fobi are working. To be honest, I'm not sure if I configuredfobi correctly (newbie issues). Here are my files: project_name/settings.py: TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [(os.path.join(SETTINGS_PATH, 'templates'))], # 'DIRS': [], # 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', "fobi.context_processors.theme", # Important! "fobi.context_processors.dynamic_values", # Optional "django.core.context_processors.request" ], 'loaders': [ 'django.template.loaders.filesystem.Loader', 'django.template.loaders.app_directories.Loader', 'admin_tools.template_loaders.Loader', ], # 'debug': DEBUG_TEMPLATE, }, }, ] And I copied the fobi folder from https://github.com/barseghyanartur/django-fobi/tree/master/src and put it at project_name/fobi Initially, when I did not have the full fobi folder copied, I had just a few templates copied to project_name/templates/bootstrap3/create_form_entry.html, and the template loaded, but then the reversed url fobi_theme.create_form_entry didn't work. All migrations are applied and the apps are added in INSTALLED_APPS. Please, help and thank you in advance. -
How to add Django middleware with custom user settings as a Python package?
I'm attempting to create Django middleware that modifies the request object by adding additional data. I want to package this middleware so that it only requires the following steps for setup: Install via PIP Add route to MIDDLEWARE in settings.py. Read custom user settings from some config file. I've been searching for ways to do this but have not found any. There are guides for creating middleware packages, but not for properly packaging them for distribution. So I have the following questions. Is it possible to install middleware via PIP? If this is possible, is there a good cookiecutter-like example to base it off of? I tried (https://github.com/pydanny/cookiecutter-djangopackage), but this assumes the package is a stand-alone app, which seems like overkill for a package that consists of a single class. What's the best way to allow a user to customize the behavior of the middleware object? Ideally, I'd like the user to pass in a callable with the custom behavior, but I'm not sure where a user can define custom settings/functionality that gets passed into the middleware upon instantiation. Thanks in advance. -
Django - Template is not displaying the entire context list that I am passing
This is driving me crazy. I ran my logic in the shell and the list I am filling is holding all the values that should be passed to the template but when the template is rendered it is only displaying the first pass of the "each_role" iteration The shell shows 8 objects being placed into the list and all I am doing is passing that to be rendered in the template. The user I am using for both test cases is my admin user that is assigned to a 'finance' and 'IT' Role hence why it showed all 8 objects. The first 5 objects are 'IT' objects and the remaining 3 are the 'Finance'. Any reason for this behavior and why it will not display all the lines on the webpage? I attached an image of the actual page rendered. Thank yoU! WebPage image Shell >>> for each_role in all_roles: ... if each_role in user_roles: ... list_of_reqs = RequisitionLine.objects.filter(assistance=each_role.id) ... for line in list_of_reqs: ... parent = line.parent_req ... if parent in req_header_list: ... continue ... else: ... req_header_list.append(parent) ... for i in range(len(req_header_list)): ... hold_line_count = RequisitionLine.objects.filter(Q(parent_req=req_header_list[i]) & Q(assistance=each_role.id)) ... for j in hold_line_count: ... req_header_line_list.append(j) ... print(j) ... … -

Django: generic ListView, only show when in other model via ForeignKey
I have two models: Creator and Piece. Per default every user is a Creator. But only if the user uploads a Piece he actually created something. Hence I would like to show in the generic Creator ListView only those Creators that uploaded a Piece. How can I filter the generic ListView to only show Creators that are present in the model Piece via a ForeignKey? models.py class Creator(models.Model): ... user = models.OneToOneField(User, on_delete=models.CASCADE) ... class Piece(models.Model): ... creator = models.ForeignKey('Creator', on_delete=models.SET_NULL, null=True) ... views.py class CreatorListView(generic.ListView): model = Creator paginate_by = 10 creator_list.html {% block content %} <h1>Creators</h1> {% if creator_list %} <ul> {% for creator in creator_list %} <li> <a href="{{ creator.get_absolute_url }}">{{ creator }}</a> </li> {% endfor %} </ul> {% endif %} {% endblock %} -

Django: How to create a dynamic related_name for an inherited parent model?
I have 4 models: class User(models.Model): name = models.CharField(max_length=255) class A(models.Model): user= models.ForeignKey("User", related_name="u_a", on_delete=models.CASCADE) title = models.CharField(max_length=255) class B(A): user= models.ForeignKey("User", related_name="u_b", on_delete=models.CASCADE) #isn't the code repeated??? b_field = CharField(max_length=255) class C(A): user= models.ForeignKey("User", related_name="u_c", on_delete=models.CASCADE) #isn't the code repeated??? c_field = CharField(max_length=255) Here, A has a ForeignKey relationsip with User and a reverse relationship as u_a. But B and C are children of A. So It appears to me as if Do not repeat your code is violated. How to overcome this? -
How to use Django Model permissions defined in Meta of the model classes for setting REST_FRAMEWORK DEFAULT_PERMISSION_CLASSES
I have models that define permissions in the Meta class as follows (not just the default view add edit delete) : class FabricInstance(models.Model): class Meta: permissions = ( ( 'sf_fabricinstance_read', 'View Fabric Instances' ), ( 'sf_fabricinstance_manage', 'Manage Fabric Instances' ), ( 'sf_fabricinstance_delete', 'Delete Fabric Instances' ), ) I want the rest framework to pick up on these permissions and return responses and allow opperations based on user's permissions. I have tried this: REST_FRAMEWORK = { 'DEFAULT_PERMISSION_CLASSES': ( 'rest_framework.permissions.IsAuthenticated', 'rest_framework.permissions.DjangoModelPermissions', ), } But the Rest framework does not pick up on the permissions I define in the Meta class. So I get Read only access to the REST API (to be clear: I am talking of when hitting the REST urls directly. No issue working programatically). Am I missing something? My understanding is that that they should be picked up by simply adding 'rest_framework.permissions.DjangoModelPermissions' in the REST_FRAMEWORK section in settings.py -

Django 2 distinct model field items
I am trying to get a list of distinct items in a field of a module and then display all the items associated with that field. For example, in a school administration system there is a school module and a student model. Each student has a color associated with them as a 'color' field. I want to create a page where the page lists all the distinct colors in the school and then under each color a list of students that belong to that color. Would I write this function in views? Here is what I have so far in views.py: class SchoolColorDetailView(DetailView): model=models.School template_name='school_app/school_color_detail.html def get_context_data(self,**kwargs): context = super().get_context_data(**kwargs) context['colors']=Student.objects.all().order_by('color').distinct('color') This will get me a list of all colors (but not by school). Is there any way to only get the colors by school and then all the students associated with that color? Do I have to create a dictionary for this? Any help would be appreciated. Thanks! -

Javascript for validating if uploaded file is image isn't working

But if I remove the validation part: var uploadField = document.getElementById("file_upload"); uploadField.onchange = function(){ if(this.files[0].size > 2097152){ alert("File is too big!"); this.value = ""; } else{ this.form.submit(); document.getElementById('celimsg').innerHTML='Analyzing image...'; document.getElementById('celi').src=gif_url; } } It started working again. Unlike other web development platform, Django doesn't support debugging for javascript and I can't put print statements on it etiher.
