TinyMCE - Displaying Text Properly - Django
I'm using the TinyMCE text editor and have it successfully integrated into my Django Website. However when I go to display the TinyMCE document with the same styling, font, color, images, etc. it just displays the content as one single line of text. I use the |safe when I display my variable of the content in my HTML file but it only shows the color and font size it does not format it like it was with indents and spacing. I found a couple of solutions but I am saving it to my Django database so I am using the CONFIGURATION in my settings.py file instead of javascript with the HTML. I'm completely stuck and coming close to a dead-line so I could really use some help. Thanks! settings.py tinymce config TINYMCE_DEFAULT_CONFIG = { 'selector': 'textarea', 'theme': 'modern', 'plugins': 'link image preview codesample contextmenu table code lists print save autosave fullscreen spellchecker textcolor', 'toolbar1': 'formatselect | bold italic underline | forecolor backcolor | alignleft aligncenter alignright alignjustify' '| bullist numlist | outdent indent | table | link image | preview', 'contextmenu': 'formats | link image', 'menubar': True, 'inline': False, 'statusbar': True, 'width': 740, 'height': 990, } HTML - display {{ … -
Different model field requirements for superuser vs normal user? django
Example(not true example): I want the superusers to have to save on register their username and email. and the normal users to save username, email, and a number(unique=True). I wanted to use the user models django has, but I don't see how when the number has to be unique? or rather I originally wanted it to be the primary key, but only for normal users. Do I have to manually make two different user classes along with the permissions, authentication etc.? or is there separate user models for admin/user in django? I tried(as a complete amateur, new to oop and django)... after gave up on using it as primary key, bc AbstractUser is fly. Tried with onetoonefield, but couldn't make a combined form with UserCreationForm, bc "too many fields error". Also weird to have an important part of the user table be in a different table (or is it?). something like (not 100% accurate): #in models.py class AdminUser(AbstractUser): username email class NormalUser(): ontoonefield(AdminUser) number(unique=True) #in forms.py class NormalUserForm(UserCreationForm): class meta: fields class onetoonefieldForm(NormalUserForm): class meta: add_field += (number) tried playing with required_fields, but again... number is unique tried making two abstractUsers... permissions errors thought about just making it non-unique and … -
why doesn't my function launch after calling it in django
I am trying to launch a script when I click on an html button with django, I get what's have been entered in the input when I click on the button but the rest of the script in my function doesn't run although when tried alone in a py file it works normally So I got here index.html : <form action='/' method="get"> {% csrf_token %} <input type="text" class="input" name="result" placeholder="Search..."> <button class="btn" type="submit"> <i class="fas fa-search"></i> </button> views.py def play(request): inp_value = request.GET.get('result', '') context = {'inp_value': inp_value} print(context) chpath = 'C:/Program Files/Google/Chrome/Application/chrome.exe %s' webbrowser.get(chpath).open('google.com') urls.py urlpatterns = [ path('', views.home, name="home"), path('/', views.play, name="play") ] So when I click on the button search, only the url change as for example : http://127.0.0.1:8000/?csrfmiddlewaretoken=xYQaShcfX3apwjaOTeYvNsiXV4qXZoG3W4K5yP582IKAljAE1o0clnCagpVW3MPT&result=hey If someone could give me a hand I would be really grateful I am not able to find why Thanks -
Run python through frontend request using Django and Docker
I need to build a website that has a form in it. This form will get info that will further be submitted to a backend python file.

Why is django-select2 ModelSelect2Widget widget not retreiving results
I am using django-select2 to represent the Department (ForeignKey) in a Model form.

Will a SSG get me better SEO, than standard server side rendering? (Django)
I am just about to make my website and I will build it with either Gatsby (React SSG) or Django. SEO and the price of the hosting are the two most important deciding factors to me. I would love to build it with Django because overall I am more experienced in it than Gatsby and I might later add things like Stripe payments, client login,... But as SEO is very important to me, I can't decide between Django and Gatsby. Is the difference in SEO significant? Thank you very much. -
Update QuerySet by attribute variable
Take for example my data below where prop is the queryset I am trying to update, and results is a dict of information. This dict has keys that are attributes in this queryset, and also has keys that are not attributes in this queryset. I only want to update this queryset if it's attribute matches... prop = Property.objects.get(pk=14) results = {'price': '525000', 'code': '55285', 'estimate': '1500'} I know this does not work as it calls for an attribute literally named 'apicall' but this is the logic that I am looking to achieve: for apicall in results: if hasattr(prop,apicall): prop.apicall = results[apicall] prop.save() How can I avoid calling literally prop.apicall and instead prop.price if it exists in the queryset? -

Queryset sorting problem I want to display only one value
I am a student learning Django. I want to add a product sorting function, and I am implementing it. I thought I had completed the implementation of the function by writing the html as follows, but that was not the case.

Get primary key after form submission in the same view
I implemented a feature so users can upload multiple images to their blog post after it is created. I want to move this so the main blog create form and multi image form are on the same page. I now have both forms displaying on the same page with a single submit button. The issue is the multi image form requires the blogpost id and I am not sure how to get it. I have tried doing a few things such as response = {} response['id'] = postForm.id` and then pass it to the second form. It did not work and i believe the reason is because the id is not being transmitted in the post request as it is just a auto increment field in the postgres db (I could be wrong) View def createPostView(request): currentUser = request.user if request.method == 'POST': postForm = PostForm(request.POST, request.FILES) test = PostImagesForm(request.POST, request.FILES) #blog post form if postForm.is_valid(): PostFormID = postForm.save(commit=False) PostFormID.author = request.user PostFormID.save() return HttpResponseRedirect("/") else: print(postForm.errors) #multi image form for f in request.FILES.getlist('images'): test = PostImagesForm(request.POST, request.FILES) if test.is_valid(): instance = test.save(commit=False) instance.post = postForm.id instance.images = f instance.save() else: postForm = PostForm() return render(request, 'blog/post_form.html', {'postForm': postForm, 'PostImagesForm':PostImagesForm,}) … -

Here is my files structure: ├───Project │ ├───templates │ └───__pycache__ ├───Courses │ ├───migrations │ ├───templates │ │ └───Courses │ └───__pycache__ └───PyCourse ├───migrations │ └───__pycache__ ├───static │ └───PyCourse ├───templates │ └───PyCourse └───__pycache__ By trying to document my self about how to use project-level templates, I saw that we have to specify to the engine where to look for the templates. That is what I meant to do in my settings.py file: TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [os.path.join(BASE_DIR, 'templates')], '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', ], }, }, ] Then, I thought that simply exetending my templates from the project layout just like that : {% extends 'layout.html' %} would work, but I am getting the following error: django.template.exceptions.TemplateDoesNotExist: layout.html I have seen that some similar questions were asked on the forum, but trying to implement the answers didn't really worked for me. It may be because these were … -

How to return 404 status code with react and django-rest-framework
I'm using react as frontend with a Django rest framework as server side to provide api to the frontend. To handle the routing of the urls, react-router is used. To handle a urls not matching any paths in the react-router, I'm using the following code: <Route component={my404component} /> This does work but it returns status code 200, how can I return 404 instead for SEO purposes? I've heard some responses that I have to use a server, but how do I do this with a django-rest-framework? Or is this related to my nginx? -

DRF pagination with ordering
Have trouble with pagination and ordering at the same time. Problem is that one instance can be returned by view multiple times: for example on page 9 and then on page 11. View: from rest_framework import filters, viewsets from django_filters.rest_framework import DjangoFilterBackend from django_filters import FilterSet from django_filters.filters import CharFilter class TariffFilter(FilterSet): concat_code = CharFilter(field_name='concat_code') class Meta: model = Tariff fields = { 'id': ['in', 'exact'], 'title': ['exact', 'icontains', 'in'], .... } class TariffPagination(PageNumberPagination): page_size = 10 page_size_query_param = 'page_size' class TariffListViewSet(viewsets.ModelViewSet): pagination_class = TariffPagination serializer_class = tariff_serializer.TariffSerializer filter_backends = (DjangoFilterBackend, filters.SearchFilter, filters.OrderingFilter,) filterset_class = TariffFilter ordering_fields = ['id', 'title', ...] search_fields = ['title', ...] def get_queryset(self): concated_code = Concat(...., output_field=CharField()) queryset = Tariff.not_deleted_objects.annotate(concat_code=concated_code) return queryset Serializer: class TariffSerializer(serializers.ModelSerializer): element = TariffElementSerializer() service = ServiceElementSerializer() class Meta: model = Tariff fields = ('pk', 'title', 'code', 'element', 'service', 'concated_code', ) Where is problem? example problem query: http://127.0.0.1:8000/api/?ordering=-title&page=2 -
Inserting objects inside a foriegn key relationship in Django
I have a recipe, and it has a list of steps, related like so: class Recipe(Model): name = CharField() class Step(Model): recipe = ForeignKey('Recipe', related_name='steps') Now when editing the recipe, I want to be able to insert a new step between two others. But when I create a new step, it always get added to the end of recipe.steps. Using recipe.steps.set([step_1, step_2, step_3]) doesn't work, as apparently set() only works on nullable fields. I'd like to avoid having to change the model just to support this, but I can't seem to find a way to do this otherwise.
