Django - parse data into javascript variable
I am working with django and a libary called gridstack.js. For this I got javascript functionality to use the libary. My idea is that the user can change the grid and press save. If he does that the data will be overritten with the new one. Now I created a Model field data = models.TextField(max_length=50000, default='{x: 0, y: 0, width: 2, height: 2}') this I call in the views.py like this: views.py def index(request): data = SaveData.objects.all() return render(request, 'main/index.html', { 'data': data }) Inside the templates javascript tag I want to give this data to a variable like let the_data = '{{ data.get.data }}';. But it dont parse the data into the js variable. I can call {{ data.get.data }} in the template and the correct data is shown. How can I add this? I already tried different variants like var the_data = JSON.parse("{{data|escapejs}}");. -

how to show the field data of one app model on the other app template?
Well I am creating a user profile where user can see his all posts which he has been uploaded.

How to Use RESTful APIs with Django
I have been trying to integrate a REST API developed using Django-rest framework with another Django web app. But stuck in passing JSON data into the front-end. I would appreciate any help. Here are my respective files. I have tried two different urls on views.py file, one is AWS API Gateway API, when used no errors are thrown but data is not displayed in front-end. AWS API JSON data where object is like {'key': 'value'}. it contains only one object though views.py def ClientList(request): response = requests.get('A URL') client_data = response.json() return render(request, 'clients/client_list.html', context=client_data) When I change the url in views.py for django-rest framework API then I get an error like "the JSON object must be str, bytes or bytearray, not list" [JSON data where objects are like {key: value},{key:value}, .... Table body was changed accordingly. FrontEnd HTML <table class="table data-list-view"> <thead> <tr> <th></th> <th>NAME</th> <th>EMAIL</th> <th>MOBILE</th> <th>ADDRESS</th> <th>ROLE</th> <th>ACTION</th> </tr> </thead> <tbody> {% for client in client_data %} <tr> <td></td> <td class="product-name">{{client.UserId}}</td> <td class="product-category">{{client.Height}}</td> <td class="product-category">{{client.Income}}</td> <td class="product-category">{{client.Age}}</td> <td> <div class="chip chip-success"> <div class="chip-body"> <div class="chip-text">{{client.role}}</div> </div> </div> </td> </tr> {% endfor %} </tbody> </table> -

Using TinyMCE with filebrowser and grappelli
I've been wanting to set up a blog app with a WYSIWYG editor. I use S3 as the storage backend for image uploads outside of the editor. For that purpose, I use "django-storages". I have deployed this on Heroku and for that purpose, I use django-heroku as well. To enable image upload for TinyMCE i went ahead and installed Grappelli and filebrowser. I added the URLs for the same added the context processor for Grappelli, set the TINYMCE_FILEBROWSER setting to true. I ensured the URLs for filebrowser and grappelli come before the URL for admin When I call collectstatic, I get this messages like this Found another file with the destination path 'admin/js/timeparse.js'. It will be ignored since only the first encountered file is collected. If this is not what you want, make sure every static file has a unique path. When I open up admin and go to the image upload button on the editor, it doesn't show the upload icon. I was wondering if anyone who has had any experience with this can help me out? I am open to setting up some time with them as well :) Here's the rundown on settings.py INSTALLED_APPS = [ 'django.contrib.admin', … -
