How to execute git command through Django migration?
I have the requirement to execute a git command in a Django migration. I need to clear the contents of a directory via a Django migration because we do not have access to the production server directly. Being new to both Django and git, I have no idea of how this could be achieved. Any help would be highly appreciated. TIA -
What to learn to implement backend of a website?
My friend, and I are learning websites. He accomplished his part by learning HTML, CSS, and even JAVASCRIPT. I on other hand have failed miserably. I learnt Python, but it's API's like DJANGO, and FLASK are a no go. I simply cannot understand them. Is there a simpler, yet effective technology out there for backend? Please help. Thank you. -
Django : select all columns when innerjoin using extra without foreignkey
I have two tables and they do not have foreign key or relationship. However, I have to do join and get all columns from both tables. This is the query I've made. query = Sms.objects \ .extra(tables=['product'], where=['product.id=sms.sms_id']) When I printed raw query, I could check it only gets tables from Sms model, not from product model. Is there any way to get columns from product model? -

Using {%extends var_name%} not being re-evaluated in jinja2 template
I am using Django and Jinja2 for email templating. Our template uses {% extends %} to dynamically derive from a base template depending on the style of email chosen by the user. It appears that the {extends} is never re-evaluated. Whichever value was supplied for the base_template parameter is always re-used. It feels like the two where textually combined. This uses the default DjangoTemplates engine I've logged all calls to cached.Loader and the base template is never re-requested {% include footer %} seem to be re-fetched from the loader every time Our email templates look like this: {% extends base_template %} {% block subject_line %} New Something Happened{% endblock %} {% block html_content %} <h2>Hello {{ name }},</h2> {% endlbock %} And we call it (through django) with context like: ctx = { base_template="emails/base/happy.html", dyn_footer="emails/footers/please_reply.html" } send_templated_email("gretting.html", ctx) I'm not sure about how Jinja2 actually behaves with {extends} and didn't see anything in the documentation saying this will or will not happen. -
Managing specific static pages acoss multiple domains in wagtail
I know wagtail can handle multiple domains to manage the sites, but after reading the documentation and browsing around what I don't understand is how exactly this works for static pages or really even where to get started. Non-static pages: I understand that the "Page" essentially replaces the model and you can defined the "content_panels" to determine what fields are editable and kick it off to a view to be rendering. Yet, I don't understand how the "@route" works with respect to pre-existing url schemas (Trying to integrate into a pre-existing project). I essentially want to move to using pages for my models so that they're openly editable through admin but keep my same url schema / setup. Maybe I misunderstand how wagtail works.... Static pages: (Main question) Right now I'm using a middleware to detect what domain im on, have a bunch of domains pointing to my app on a server through CDN since they share the same codebase, and then patch the root urlconf to use that apps urls file. So, I have domains xyz.com, abc.com, def.com, etcetera which are controlled by their respective apps (code is interrelated) and I'm simply rendering the (non-wagtail) template for their static … -

Django filter query with foreign key
I want to filter query based on three user inputs. Depart City, Arrive City and Date. Depart City and Arrive city are on the same table called Route while the TravelDate is a foreign key in Route.

If a bus is available on that date from city A to city B will be calculated by doing doing something like this if (d - TravelDate.start_date)% TravelDate.interval =0 then display the results to the user.

Querying hits per hour on Django timezone aware setup

Raw query and row level access control over multiple models in Django
I'm trying to provide an interface for the user to write custom queries over the database. I need to make sure they can only query the records they are allowed to. In order to do that, I decided to apply row based access control using django-guardian. Here is how my schemas look like class BaseClass(models.Model): somefield = models.TextField() class Meta: permissions = ( ('view_record', 'View record'), ) class ClassA(BaseClass): # some other fields here classb = models.ForeignKey(ClassB) class ClassB(BaseClass): # some fields here classc = models.ForeignKey(ClassC) class ClassC(BaseClass): # some fields here I would like to be able to use get_objects_for_group as follows: >>> group = Group.objects.create('some group') >>> class_c = ClassC.objects.create('ClassC') >>> class_b = ClassB.objects.create('ClassB', classc=class_c) >>> class_a = ClassA.objects.create('ClassA', classb=class_b) >>> assign_perm('view_record', group, class_c) >>> assign_perm('view_record', group, class_b) >>> assign_perm('view_record', group, class_a) >>> get_objects_for_group(group, 'view_record') This gives me a QuerySet. Can I use the BaseClass that I defined above and write a raw query over other related classes? >>> qs.intersection(get_objects_for_group(group, 'view_record'), \ BaseClass.objects.raw('select * from table_a a' 'join table_b b on a.id=b.table_a_id ' 'join table_c c on b.id=c.table_b_id ' 'where some conditions here')) Does this approach make sense? Is there a better way to tackle this problem? Thanks! -
dynamically add instances of a model in Django forms

I'm imagining something like having a form for the first instance (with fields "activity", "activity_type" and "activity_code") and then, if the user clicks a "plus sign" (or whatever), (s)he can add a second, third...Nth instance to the database. -
Django Foreign Key lookup into Template
