Jinja2 templating with components? blocks? templates?
A little question to jinja2 templating: I want to create a reusable template to include and then overwrite blocks. Macros do not let me write junks of HTML easily as parameters do they? Say I want to reuse an include several times and am using BIG junks of HTML in blocks that I want to dynamically assign how would I do it? certainly not with macros I guess, or am I wrong? {% render_foo('bar',2) %} is fine {% render_foo('<table><tr><th>something</th><th>somethingelse</th></tr><tbody><tr>....etc') %} is not fine any more is it "what do you really want to do?" yes, what I told you, I have a way I create containers for my data. The container is ALWAYS the same. The content is completely different on each usage. Once a table. Once a bootstrap component. Once a form. The surrounding elements are always the same to reproduce the simple error this is what I did: {% include 'full_section.html' %} {% block fullsection %} <table><tr><th>something</th><th>somethingelse</th></tr><tbody><tr>....etc{% endblock %} {% include 'full_section.html' %} {% block fullsection %} <form>//some cool LONG big form </form>{% endblock %} full_section.html contents just for completeness, it is a lot more complex in reality <div class="my_cool_full_section"> {% block full_section %}{% endblock %} </div> TemplateAssertionError: … -
How to redirect to the Startup object detail after the user updates/deletes/creates a Post (or cancels in either of the 3 cases)
To use the Django Unleashed schema, suppose the user is on a Startup detail page and starts to create a Post, then decides to cancel. If I wanted the cancel button to redirect to a Startup list, that's easy: href="{% url 'organizer_startup_list' %}" class="button button-primary"> Cancel ...but the user expects it to redirect to the Startup detail. Something like {% url 'organizer_startup_detail' startup.pk %} comes to mind. The problem is there's no startup object in the context. So I need to put the startup object in the context when the user goes to create or update or delete a Post, but the author is using ObjectCreateMixin in the organizer app, so its difficult to customize. His view looks like: class StartupCreate(ObjectCreateMixin, View): form_class = StartupForm template_name = 'organizer/startup_form.html' -
Dashes instead of Date-Time in djangotables2
I am getting dashes in my Django table for all of the columns that are supposed to be showing a date and time.

The non date fields (except for one...different issue...are showing up correctly). -

Django page not found when deleting object with foreign key (1 to many)
This is my first time trying to delete objects with a foreign key. The models have a 1 to many relationship: class NumObject(models.Model): title= models.CharField(max_length=50) number= models.IntegerField() ident= models.IntegerField() usersave= models.CharField(max_length=100, blank= True) def __str__(self): return self.title def save(self, *args, **kwargs): super(NumObject,self).save(*args,**kwargs) def get_absolute_url(self): return reverse('posts:detail', kwargs={'id': self.id}) class Sounds(models.Model): numobj = models.ForeignKey(NumObject) title = models.CharField(max_length=50) sound = models.FileField() def __str__(self): return self.title def get_absolute_url(self): return reverse('posts:detail', kwargs={'title': self.title}) The views for the NumObject and Sounds look like this: def post_detail(request,id= None): instance= get_object_or_404(NumObject, id=id) context= { 'title': instance.number, 'instance': instance, } return render(request,'post_detail.html',context) def sound_detail(request,id= None): instancesound= get_object_or_404(Sounds, id=id) context= { 'sound': instance.number, 'instancesound': instancesound, } return render(request,'sound_detail.html',context) in my template, I'm able to display all "Sounds" objects associated with a "NumObject" object by doing this: {% for obj in instance.sounds_set.all %} {% include 'sound_detail.html' %} {% endfor %} sound_detail.html has a ul that displays all the sound objects, as well as a link to the delete view for each sound object: <a href="/{{instance.id}}/delete/">Delete</a> The url for the delete view looks like this: url(r'^(?P<id>\d+)/delete/$', views.post_delete, name= 'delete'), And the delete view: def post_delete(request, id): sound= get_object_or_404(Sounds, pk=id).delete() return redirect('posts:list') For some reason, when I try and delete the individual … -
node js multi part file upload to django not showing my file in request.FILES.get('filename')
I'm using the requests npm library for node js and attempting to do a multipart upload to an api. How can I set up my body of my post request to be properly be recognized by [request.FILES.get('filename')][1] In the django framework? I'm currently formatting my post request as shown below. body = {file_size: bytes ,checksum_sha256: sha256, checksum_md5: md5, part: i} I'm really not sure how to tie declaring the image a file so the django framework recognizes it, naming it, and actually linking the data together with fs.createReadStream(filepath); Any help would be appreciated. -
Django / Django REST Framework: serializer.is_valid() false and can't save web API query to Postgres
When I run from manage.py shell the following: from accounts.views import * c = ExtractCRMDataAPIView() c.crm() It evaluates to Failed. per the code in my views.py. I looked into the conditions where serializer.is_valid will be false per (serializer.is_valid() failing though `required=False` - Django REST Framework), and my model and serializer meet the criteria of optional fields being blank=True and required=False. Furthermore, while I know the query is successful because I can run it in its own crm.py and have it print in the console, this is not saving the web API query result to the database and I am not sure why.

Django Tables 2 - Accessing Fields
I recently upgraded from django-tables (version 1) to djangotables2 in order to upgrade my code to Django 1.11 (from Django 1.6). I have a table containing several fields, and I am trying to access specific fields. The following code is not working in the HTML: <td>{{ item.entered_by }}</td> <td>{{ item.last_updated|date:"m/d/Y j:i a" }}</td> I can iterate through all fields, and all fields will be displayed if I write: {% for field in item%} <td>{{ field }}</td> {% endfor %} However, I only want certain fields to be printed (for instance, the 'entered_by' and 'last_updated') fields. How can I do this/check the field name? I've looked through the documentation here: http://django-tables2.readthedocs.io/en/latest/pages/api-reference.html# without success. -

Django: activate user-stored language after login
I'm using Python 3.6 and Django 1.11. I'm using Django class-based auth views and custom user model. My users have their language stored in database. I would like to retrieve this language after every login and activate it. I was hoping to do this through user_logged_in signal, but signals cannot affect response in any way, so this is not possible. Another way is to override default auth views, which is something I wanted to avoid. Is there any other way? Thank you. -
Django Rest Framework and Select Lists
Suppose that I have a contact form, in which one of the informations I want my users to supply is the department from a predefined list of values. Using the DRF, what is the best or the correct approach to implement such form? Let's say I'm using Vue or Angular on the front-end. When its time to present the HTML to the user, is it better to query the back-end for the available values, or can I just hardcode the values on the HTML? Although the second approach is the easiest, I think it is not the best, since it will be a lot of work when there's a need changing/adding/removing values from this list (assuming this same select list is used multiple times through the application).
