Change html layout (list, thumbnails, tiles..) for the same Django View
What is the simplest way to change some html dynamically (i.e. on a button press) to create different layouts for a Django (python) view? I have a view that presents a list of records. And I would like the User to be able to quickly flick between a text list and thumbnail images etc. Thanks! -
class httpresponse results in 405 - django
I am new to django and I am trying to understand class views. In urls.py (main) I have: from django.conf.urls import url, include from django.contrib import admin urlpatterns = [ url(r'^admin/', admin.site.urls), url(r'^', include('webapp.urls')), ] in webapp folder I have: urls.py (webapp): from django.conf.urls import url from webapp.views import Firstapp urlpatterns = [ url(r'^whatever$', Firstapp.as_view()), ] views.py (webapp): from django.shortcuts import render from django.views import View from django.http import HttpResponse class Firstapp(View): def something(self): return HttpResponse('Yes it works!')

Django-filer, Relating a record to a stored image without using Admin (Django)
I have made a script that will convert a CSV into data and insert it into my table. Now this table has a imagefilerfeild, from django-filer. I need to bypass the admin widget and just pass in a primery key or some peice of information that can be used to relate the image to the record. entry.image = Image.objects.get(file='filer_public/e3/83/e383cd94-c28a-485b-8307-f4107698ad1d/keypad-sm-keypad.jpg') Is there a way to assign a record an image within filer without selecting it from the widget in the admin? -
Unable to print array into HTML
I have a program which is pulling data from the database like so. Views.py def final(request): total = [] name = [] k = 0 for i in Question.objects.raw("SELECT name, question1, question2, question3, question4, question5, question6, question7, question8, question9, question10 FROM music_question"): name.append(str(i.name)) total.append(int(i.question1) + int(i.question2) + int(i.question3) + int(i.question4) + int(i.question5) + int(i.question6) + int(i.question7) + int(i.question8) + int(i.question9) + int(i.question10)) return render(request, 'music/final.html', {"totals": total, "names": name, "rows": Question.objects.all()}) From here I'm trying to print into HTML like so final.HTML </body> <script type=text/javascript> data = {{totals}} console.log(data) </script> </html> I can see that the data from the database has returned to the console in Chrome but it won't persist onto the web page and I'm not sure where I'm going wrong. -

ASP.NET api post nested model
i was a django user and recently transfered to ASP.NET . currently my api post works like this. POST : http://localhost:55974/api/trades/ { "id": 1, "baseProduct": { "id": 1, "productID": "sample string 2", "tags": [ "sample string 1", "sample string 2" ] }, "productDescription": "sample string 2", "images": [ "QEA=", "QEA=" ], "price": 3, "estimatedShippingDate": "2017-03-31T20:41:03.2760924+09:00" } but what i want is to link the existing data with its id something like this. { "id": 1, "baseProduct": 1, "productDescription": "sample string 2", "images": [ "QEA=", "QEA=" ], "price": 3, "estimatedShippingDate": "2017-03-31T20:41:03.2760924+09:00" } you can note that baseProduct has changed to its id. but when i try to do this, i get this error { "Message": "The request is invalid.", "ModelState": { "tradeModel.baseProduct": [ "Error converting value 3 to type 'EodiRoad.Models.BaseProductModel'. Path 'baseProduct', line 2, position 19." ] } } well this worked fine on django so.. i guess that it will have its way on asp.net to.. any possible solutions? -
Django - how many views and templates
I've got some script generating CSV files and I would like to present these data on the web page. I'm new at Django and I'm wondering how I can use Django for my project. Please refer to this scheme https://drive.google.com/open?id=0ByiuoauCCrVrMkg1bHdjMUE4amM. For now in searchengine.py I'm typing prices, sizes and brand manually and running script manually. I'm not going to use models so I need only views and one template. Do I need only one template? I need only one page but with multiple subpages beacuse of pagination. I don't want to display all 200 tiles on one page. How many views do I need? Is one view common for every tile on any subpage? Is any search field or button or pagination elements a separate view or I should create all elements inside one view? Can you point me some exaple of similar simple Django project? -
Import a string value from first loop to second loop in template?

Django queries: get dictionaries together with model instances
The documentation for .values says .. Returns a QuerySet that returns dictionaries, rather than model instances, when used as an iterable. .. with following the example: >>> Blog.objects.values('id', 'name') <QuerySet [{'id': 1, 'name': 'Beatles Blog'}]> I'm looking for a way where I get both, i.e. something like this <QuerySet [(<Blog: Beatles Blog>, {'id': 1, 'name': 'Beatles Blog'})] Note: yes, it's a dump example and it mustn't be a tuple inside a list, it's just a way to express my needs. -

Django 1.10.6 - MP3 Upload and player
For a job interview I need to code a website consisting of at least 3 pages for a fictional band's website using Django. My idea is to: have a front page with blog posts from the band, the most recent one on top. have an admin page where I can upload the band's songs. have a page with a list of songs that can be played by clicking on the song. I know very basic html and css (did some one codecademy). I did the Django tutorial up until part 6 https://docs.djangoproject.com/en/1.10/intro/tutorial06/ I'm just not very sure how to go about doing this. (Would I use "static files" for the mp3's? How does one set up a blog format page?) So I'm just hoping for a nudge in the right direction. Any links to tutorials or books or anything that might be useful would be much appreciated. -

What template is loaded by Django?
I was following Django tutorial, and got stuck where it asked me to replace the default template for administrative part of the site with my own. The problem was a typo in the template's name. I suspected there must be a problem like that, but to troubleshoot the problem it'd be very helpful to see some kind of report from Django on what template it used to render a particular page. Is there any way to do this? -

How can I register a custom management command that is tied to the project, not the app?
I have a django project whose functionality is split into several interdependent apps. I want to write a custom management command that deletes data from the database and files from the media directory for easy testing in the dev environment. My management command works if I put my management/commands/custom_command.py in an app directory, but it won't work it it's in the base project directory. That feels wrong, as it deletes model instances from several apps, not just the one in whose directory it resides. The docs don't seem to cover what to do in this case. What's best practice in my situation? -
How to replicate Microsoft Word, by being able to add images to text editor?
I'm currently using django pagedown for my text editor: https://github.com/timmyomahony/django-pagedown, which has a <textarea> as the body of the editor. However i'd like to be able to add images within the actual editor, similar to Microsoft Word. Though I've been told I can't add divs to a <textarea>, so would I have to make a text editor myself? Really don't think i'm capable of doing that so is it possible to implement this feature to my current text editor or maybe another one that already has this feature? How would I do this? PS: All text editors can add images which displays the file path of the image, which then renders after the post has been posted. However like I said I want the actual image to show before the post is submitted, like Microsoft Word which shows the image instantaneously.
