Like, Django Do you want any text information in the template?
Like, I have a few pages. Main and about us.♪ The page should include several blocks of textual information that can be edited through the Adminka.
The number of blocks is fixed and different for each page.
Modelling isn't right here. Please.

The simplest and most obvious way is to keep the template in the database. Create a model, in the simplest case, containing a text field and the name of.
```
from django.template import Template
from myapp.models import DbTmpl
a = DbTmpl.objects.get(name='contacts').html

tmpl = Template(a)

tmpl.render({'phone' : '111-22-33', 'city' : 'Moscow'})
```
It's up to the task and the fantasy.
In addition, for such cases, there is a battery: http://django-dbtemplates.readthedocs.org/en/latest/

UPDATE: He left you the link with the library I made, I hope it will still serve you. https://github.com/BrandonVargas/AndroidOCRFforID I just did one, unfortunately I can't make it public, but I can guide you a little. I'm using Mobile Vision as you mention, before using Tesseract which is very good but increases the size of your application too. To start, you should know that there are 5 types of IFE/INE A, B, C, D and E of which the only one that is not in force is type A. Now for a correct reading of the fields the first thing you need to do is cut the photo to the size of the IFE/INE to remain as the image you show, once done this is to take measures, like doing it? Let's take the picture you put as a reference. Suppose we need to draw the name, and the image measures 5.4 high by 8.6 wide. We know that android takes the origin of an image in the upper left corner, we take the measurements from there, the name starts at 0.3 cm in X and 1.6 cm in Y, it has an average width of 4 cm and a height of 1 cm. Once these measures are taken as a basis, the "percentages" would be removed and X = (0.3/8.6), Y = (1.6/5.4), ANCHO = (4/8.6) and ALTO = (1/5.4). Having this data we can create a bitmap of the name from the cut above and pass it to the API. It is important to take out these "proportional" data as there is a variety of cameras in Android and the photos are of various sizes. When I can publish the library that I edited this. Greetings.

The problem is the following:In order to get to cursor.execute() you require sentencing2. To be able to assign something to sentencing2 you have to have received by post 'select' and in case of receiving it that is by force 'div1' or 'div2' since otherwise sentence2 does not exist or is assigned, a possible solution is the following:sentencia2 = None # Inicializar sentencia2 para que no diga que se referencio antes de asignar if request.method=="POST": select = request.POST.get('select', None) # Si viene select en el post guardar si valor, si no asignar None if select: if select == 'div1': op= request.GET('op0') fecha_ini = request.POST['fecha_ini_0'] fecha_fin = request.POST['fecha_fin_0'] articulo = request.POST['articulo0'] sentencia2 ="exec [PR].[dbo].[PR_PR]" + str(rec_sistrade) + "," + emp + "," + op + "," + fecha_ini + "," + fecha_fin elif select == 'div2': op= request.POST['op1'] fecha_ini = request.POST['fecha_ini_1'] fecha_fin = request.POST['fecha_fin_1'] articulo = request.POST['articulo1'] sentencia2 ="exec [Empresa].[dbo].[PT_GET_ORDENES_EVENTOS]" + str(rec_sistrade) + "," + emp + "," + op + "," + fecha_ini + "," + fecha_fin if sentencia2: # Validamos que sentencia2 exista para ejecutar cr = cursor.execute(sentencia2) resultstable= namedtuplefetchall(cr)

Although your current code is suitable for a table that crosses products with stores (such as in https://pt.stackoverflow.com/q/96493/215 that originated this whole code), this new structure would benefit more than a different strategy. In particular, it is possible to cause "heavy work" to be done by the database itself, and the treatment in the view is much smaller. Not only should performance improve, as the code you would need to write would be much smaller.RefactoringYour case is quite similar to https://pt.stackoverflow.com/q/52125/215 . Adapted, it would be:Imports and auxiliary variables:from django.db.models import F, Min, FloatField pega_total = F('price') * F('quantity') pega_total.output_field = FloatField() Start the search Quotation:Quotation.objects. Find the lowest price of each product, and calculate the total (price x quantity):.annotate(menor=Min('product__quotation__price'), total=pega_total). Filter only the items whose price is equal to that minimum:.filter(price=F('menor')). [if supported] Eliminates duplicates (two stores that offer the product for the same value); not supported by all BDs:.distinct('product'). (No SQLite gave NotImplementedError: DISTINCT ON fields is not supported by this database backend)Order by store:.order_by('store__store'). Take the values that interest you to set up the table:.values('product__product', 'price', 'quantity', 'total', 'store__store') So you already get the data you need for your table in a single query:from django.db.models import F, Min, FloatField pega_total = F('price') * F('quantity') pega_total.output_field = FloatField() qs = Quotation.objects.all(). annotate(menor=Min('product__quotation__price'), total=pega_total). filter(price=F('menor')). distinct('product'). order_by('store__store'). values('product__product', 'price', 'quantity', 'total', 'store__store') context = { "linhas":list(qs) } And in the template:{% for linha in linhas %} <tr> <td>{{ linha.product__product }}</td> <td>{{ linha.price }}</td> <td>{{ linha.quantity }}</td> <td>{{ linha.total }}</td> <td>{{ linha.store__store }}</td> </tr> {% endfor %} Adding subtotal and totalAs the data already come ordered by store, calculating the subtotal is easy: just go by line by line and accumulating, and when the store changes (or the stores end), include a special line for the subtotal:qs = ... subtotal = 0 total = 0 ultima_loja = None linhas = [] for linha in qs: if ultima_loja is not None and ultima_loja != linha['store__store']: linhas.append({ 'subtotal':subtotal }) subtotal = 0 linhas.append(linha) ultima_loja = linha['store__store'] subtotal += linha['total'] total += linha['total'] if ultima_loja is not None: linhas.append({ 'subtotal':subtotal }) linhas.append({ 'total':total }) context = { "linhas":linhas } And in the template:{% for linha in linhas %} <tr> {% if linha.product__product %} <td>{{ linha.product__product }}</td> <td>{{ linha.price }}</td> <td>{{ linha.quantity }}</td> <td>{{ linha.total }}</td> <td>{{ linha.store__store }}</td> {% elif linha.subtotal %} <td></td><td></td><td></td> <td class="subtotal">{{ linha.subtotal }}</td> <td>SUBTOTAL</td> {% else %} <td></td><td></td><td></td> <td class="total">{{ linha.total }}</td> <td>TOTAL</td> {% endif %} </tr> {% endfor %} Note: if you're curious, that's the SQL that query suggested in this response generates (except for the part of distinct that didn't work here):SELECT "app_product"."product", "app_quotation"."price", "app_quotation"."quantity", "app_store"."store", ("app_quotation"."price" * "app_quotation"."quantity") AS "total" FROM "app_quotation" INNER JOIN "app_product" ON ( "app_quotation"."product_id" = "app_product"."id" ) LEFT OUTER JOIN "app_quotation" T3 ON ( "app_product"."id" = T3."product_id" ) INNER JOIN "app_store" ON ( "app_quotation"."store_id" = "app_store"."id" ) GROUP BY "app_quotation"."id", "app_quotation"."product_id", "app_quotation"."store_id", "app_quotation"."price", "app_quotation"."quantity", ("app_quotation"."price" * "app_quotation"."quantity"), "app_product"."product", "app_store"."store" HAVING "app_quotation"."price" = (MIN(T3."price")) ORDER BY "app_store"."store" ASC

Regis,I know a way to do this you want without creating a new filter, or changing the context of your View.To create a new filter you can look at https://docs.djangoproject.com/en/1.9/howto/custom-template-tags/ , but well summarized you would do so:First you register your new filter:@register.filter def count_published(value): return value.filter(published=True).count() Then you use it in the template:{% load seu_arquivo_de_template_tags %} <p>Livros publicados: {{ books | count_published }}</p> There is another way to do that would also be the modification of get_context_data of your ListView:class BookList(ListView): model = Book context_object_name = 'books' paginate_by = 10 def get_context_data(self, **kwargs): context = super(BookList, self).get_context_data(**kwargs) context['count_published'] = self.model.objects.filter(published=True).count() return context And then use in your template the context variable:<p>Livros publicados: {{ count_published }}</p>

The view Detail do not necessarily make it generic, whatever you go through the URL you capture it in your view and use it as you wish, in this example the variable is taken username that went through the URL:path('object/< str:username >', myproject.DetailObject, name='detail_object') Then in the view the object that is related to the user is sought using the username by contextdef DetailObjectRequest(request, username): requests = MyObject.objects.filter(user__username=username) return render(request, template_name='package_details.html', context={'object':requests}) I hope it serves you.

If you're going to take out all the shadows, they're already available to objects that were tied to as a manager. Which means you can get them by calling the method all.{% for tag in article.tags.all %} {{ tag }} {% endfor %} If you need specifics, such as those that contain a word, it will be necessary to refer to the context the filtered queryset tags, or to the Articket model the method that will retrieve this filtered queryset.With regard to references, attention to https://ru.stackoverflow.com/questions/998235/%D0%9A%D0%B0%D0%BA-%D1%81%D0%B4%D0%B5%D0%BB%D0%B0%D1%82%D1%8C-%D1%87%D1%82%D0%BE%D0%B1%D1%8B-%D0%BF%D0%BE-%D0%BD%D0%B0%D0%B6%D0%B0%D1%82%D0%B8%D1%8E-%D0%BD%D0%B0-%D1%81%D1%81%D1%8B%D0%BB%D0%BA%D1%83-%D0%BF%D0%BE%D0%BB%D1%8C%D0%B7%D0%BE%D0%B2%D0%B0%D1%82%D0%B5%D0%BB%D1%8C-%D0%BF%D0%B5%D1%80%D0%B5%D0%BD%D0%B0%D0%BF%D1%80%D0%B0%D0%B2%D0%BB%D1%81%D1%8F-%D0%BD%D0%B0-%D0%BD%D1%83%D0%B6%D0%BD%D1%83%D1%8E-%D1%81%D1%81%D1%8B%D0%BB/998294#998294

And the database is filled with data? If you don't, just clean it up, delete all the files from the migrations folder in all the project applications and migrate again. If you have the data, first unload the base and repeat the top point, then the base is back.

I'm not sure, but when the error tells you that the class is not installed, as your error message says: 'Occurrence', which is either not installed, or is abstract. It means that Django She doesn't find that class and this can be because she's not added to it. settings.py in instaled_apps. Try to add 'django-scheduler'.INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'django-scheduler', ]
