In djangocms-picture how to set a default maximum image size?
I would like to set a default maximum size of images in the djangocms-picture plugin. I would like to do this at template level. This simple template for example: {% load thumbnail %} <img src="{% thumbnail instance.img_src 'golden_ratio_xlarge' %}"> Gives this error: SuspiciousFileOperation at /en/ The joined path (/media/filer_public_thumbnails/filer_public/a3/07/a3073ea1-a798-43c0-869f-689de5f53e7e/sawa.png__420x233_q85_subsampling-2.png) is located outside of the base path component (/home/mogoh/src/git.noc.ruhr-uni-bochum.de/ceres/website/ceres/media) -
Using Python/Django how do I substitute values from an external source into an HTML page
I am relatively new to Django and am trying to substitute values from an external source into an HTML page? Using the following HTML snippet: <div>UID: -3SDfguwvNuurPe44AnUjGdzOj_guWVP3QPjmhZyWsA1</div> <div>Validic ID: 5e220365bdb13500b03075a2</div> <div>Created: 2020-01-17T18:56:37Z</div> <div>Updated: 2020-01-17T18:56:37Z</div> I want to replace the text value for each of those rows (to the right of the "key:" with the value retrieved from a JSON response for each of the "keys". I have tried: <div>UID: {{ display_uid }}</div> <div>Validic ID: {{ display_vid }}</div> <div>Created: {{ display_created }}</div> <div>Updated: {{ diplay_updated }}</div>``` The examples I have found have shown how to build forms and use text fields/text areas, but nothing for a plain HTML page. Anybody got suggestions? Thanks. Jeff Brown -

Replicating Django forms request.FILES to upload multiple image files using smartfields
I'm trying to take a single image using Django forms and upload it with resized version under 3 headers. I'm even able to do so with request.POST QueryDict but not with request.FILES MultiValueDict even after it shows filled data for respective field names. My Views.py def image_add(request,article_id): template_name = 'blogs/image_add.html' articles = Article.objects.get(article_id=article_id) form = ImageAddForm if request.method == 'POST': image = request.FILES["image_1080"] request.FILES['image_800'] = image request.FILES['image_350'] = image print(request.POST) print(request.FILES) form = ImageAddForm(request.POST, request.FILES) if form.is_valid(): new_form = form.save(commit=False) new_form.dir_id = article_id new_form.save() return redirect('/') context = {'form':form,'articles':articles} return render(request, template_name,context) My Models.py from smartfields import fields from smartfields.dependencies import FileDependency from smartfields.processors import ImageProcessor class Images(models.Model): dir_id = models.CharField(max_length=10,null=True) image_1080 = fields.ImageField(upload_to=img_1080_dir_path, name="image_1080", dependencies=[ FileDependency(processor=ImageProcessor( format='PNG', scale={'max_width': 1080, 'max_height': 1080})) ]) image_800 = fields.ImageField(upload_to=img_800_dir_path, blank=True, name="image_800", dependencies=[ FileDependency(processor=ImageProcessor( format='PNG', scale={'max_width': 800, 'max_height': 800})) ]) image_350 = fields.ImageField(upload_to=img_350_dir_path, blank=True, name="image_350", dependencies=[ FileDependency(processor=ImageProcessor( format='PNG', scale={'max_width': 350, 'max_height': 350})) ]) My Forms.py class ImageAddForm(forms.ModelForm): class Meta: model = Images fields = ('name','alt_text','image_1080') widgets = { 'name': forms.TextInput(attrs={'class': 'form-control'}), 'alt_text': forms.TextInput(attrs={'class': 'form-control'}), 'image_1080': forms.ClearableFileInput(attrs={'class': 'form-file-input'}) } This saves only one image - 'image_1080' but not the other two. -
Querying model by ForeignKey to receive data in another ForeignKey?
I am having trouble running a query through a table that I built as basically a linkage type table to link Company and Package class CompanyPackageLink(models.Model): company = models.ForeignKey('business.Company', related_name='company_packages') package = models.ForeignKey('business.Package', related_name='packages') I am trying to query the CompanyPackage table by company and then retrieve all packages associates to that query. I have something like... company = Company.objects.get(employee=self.request.user) company_packages = CompanyPackageLink.objects.filter(company=company).select_related('package') Now this returns a correct quesyset, but it returns the CompanyPackage instance. <QuerySet [<CompanyPackageLink: companyA: PackageA>, <CompanyPackageLink: CompanyB: PackageB>]> I would like my query to return the actual Package model instance where I can retrieve name, price, etc. So I would like the returned queryset to actually return this.. <QuerySet [<Package: $100.00>, <Package: $200.00>]> Any help is appreciated! -
Adding a language field to the login template in Django
I have to start a project in Django, which should be able to translate in three languages (Spanish, English and Italian). I have the 3 languages defined within the settings.py file, as it looks: LANGUAGES = [ ('es', _('Español')), ('en', _('English')), ('it', _('Italiano')), ] My intention (I am not sure if it is the one indicated) is that when the user logs in, they enter their username, their password and the language with which they will work and from there the application establishes the menus, forms, etc. according to to the indicated language. My first approach was to extend the user model by incorporating a language field, as seen: class User(AbstractUser): language = models.CharField(max_length=10, choices=settings.LANGUAGES, default=settings.LANGUAGE_CODE) modifying the AUTH_USER_MODEL variable: AUTH_USER_MODEL = 'usuarios.User' and modify the login form, as it looks: class LoginForm(ModelForm): def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) #self.fields['username'].widget.attrs['autofocus'] = True class Meta: model = User fields = 'username', 'password', 'language' widgets = { 'username': forms.TextInput( attrs={ 'placeholder': 'Ingrese su username', } ), 'password': forms.PasswordInput(render_value=True, attrs={ 'placeholder': 'Ingrese su password', } ), 'language': forms.SelectMultiple(attrs={ 'class': 'form-control select2', 'style': 'width: 100%', 'multiple': 'multiple' }) } As well as, add one more field to the login template: <div class="form-group form-primary"> {{form.username|add_class:'formcontrol'|attr:'type:text'}} … -
How to re-display formset & Select2 field with selected value on form error in Django
After searching for several days and trying different options, I decided to finally post the issue and question. I have a template that has a form and 2 different formsets. One of the formsets uses an intermediate model with a GenericForeignKey that will reference two other models. For the formset, I am using an inlineformset and adding a CharField which is used with Select2 to make an ajax call to check the two other models. The value returned by the ajax call will be a json/dict with 3 key/value pairs. The issue I am having is that when the template is submitted and there are errors, how can I redisplay the value that was entered in the Select2 CharField when the template is presented again? The value is in self.data and is sent back to the template. However, everything I've tried so far will not redisplay the select2 field with the value selected previously or the values that were submitted. The submitted values are returned to the template in a json/dict, key/value, format under form.fieldname.value but I am not sure how I can use that to repopulate the select2 field. I appreciate any suggestions or links. If there is an … -
Django: return distinct set of many to many relationship belonging to a particular model
I want a query that returns all the distinct tags belonging to all the entries in Model A. I suspect it's possible with clever query and a bit of filtering, but I can't work it out. I want to minimise database hits. Models: class Tag(models.Model): name = models.CharField(max_length = 50,) category = models.CharField(max_length = 50, blank=True) class A(models.Model): ... tags = models.ManyToManyField(Tag, blank=True) class B(models.Model): ... tags = models.ManyToManyField(Tag, blank=True) My solution in the meantime is: tags = list() for a in A.objects.all(): for t in a.tags.all(): if t not in tags: tags.append(t) Is there an elegant solution to achieve the above functionality? -

Django Test Client returning error on client.get(reverse('polls:index'))
working through the Django tutorial and running into issues. Patience appreciated! I'm on part 5 attempting to use the test client. When I run: > response = client.get(reverse('polls:index')) I get the following error: TemplateSyntaxError: Invalid block tag on line 38: '<span', expected 'empty' or 'endfor'.

Stop forloop tag template - Django
I am trying to stop a "forloop" tag template in Django, but I couldn't find a way to do that. In my Django template, I want to show all the articles that I have in my database. And each of those articles is connected to one or more SDGs. For now, my code is showing all the related SDGs, but I would like to only show the first result, and thus stop the "forloop" as soon as there is one positive result. Would someone know how to do that? Here is my Django template: <section> <div class="row px-4"> {% for article in articles %} <div class="col-md-12 col-lg-3 px-3 mb-5" data-aos=fade-up> <div class="card shadow lift rounded"> <div class="card-body py-4"> <h3 class="card-title">{{ article.title }}</h3> {% for sdg in sdg_seed_image %} {% if sdg.seed_id == article.id %} <h4>{{ sdg.sdg_id }}</h4> {% endif %} {% endfor %} </div> </div> </div> {% endfor %} </div> </section> Here is my view code: def article_view(request): articles = Article.objects.all().order_by("-date_publication") sdg_seed_image = SDG_Seed.objects.all() return render(request, "dist/inside/article/view_all.html", context={"articles": articles, "sdg_seed_image": sdg_seed_image})
