I would like to know if Google Docs API or any other spreadsheet (xls) API or any reporting tool works with GAE, Django & application data from BigTable. In other words, I would like to generate spreadsheet with rich formatting - colors, fonts and upto 50 sheets in each file. And send this spreadsheet as E-Mail attachment to user or download using browser.
Thanks a lot,
Sandeep
I've used openpyxl to good effect with Django + AppEngine. Openpyxl can do styles and sheets and formatting and all that stuff, and saves to an .xlsx file. If you need .xls files, then perhaps have a look at something like xlwt.
If your spreadsheets are under 1MB, then they can be saved in/served with the Datastore just fine. Otherwise, you can use the Blobstore, but that would require using the AppEngine API instead of pure Django.

I have a postgresql database and I want to add data to it.
I want to upload an excel file containing the data and save it to database.
I have a backend server of django and a frontend server of React.
I am easily able to import the data from the excel sheet to database using django_import_export but from the django admin.
What I want is, to do this using React and for normal users(non superusers) also. Is there a way to integrate django_import_export with react? Any other way to implement this functionality is also apreciated.
Presumably your backend uses a REST API to handle requests from the frontend. So, you can write an API handler which receives the Excel data posted to it.
The Django API handler can create an import process to handle upload. Check the documentation for more information.
Note that if you are loading large files, then you might want to handle the upload asychronously. This is little more tricky, but you could look at Celery to help with this.
I am using Django 1.4 on Google App Engine.
I have a model called Media, where the admins can upload files to use in their website. It has a field:
file = models.FileField(upload_to='/uploads/%Y/%m/%d')
It works perfectly with images (although the URL provided is weird), but that is not a problem.
The problem is when they try to upload a PDF (or anything else). Everything seems to work, but when you go to edit it, it doesn't contain any file - there is no "Currently" or anything else.
If I go to Google App Engine dashboard, the file is in Blob Viewer, and the record is also saved and available through the Datastore Viewer, with the correct blob key.
Why Django is not recognizing it? And how I can fix it?
djangoappengine contains a storage provider for the blobstore.
To me it doesn't seem like a full-featured solution, just something to get file uploads running.
I had to add this to get some functionality I needed (urls to the files).
It might make the admin work too:

I'm not sure where to begin, as in do I start working towards PHP, Ruby or what, but here is what I'd like to do:
I have a Python script that takes a pre-formatted Excel document and using xlrd and Django, I output a nicely formatted HTML page, based on a template HTML page.
But currently on my team, I'm the only one that can use this Python script because our setups, and I'd like to simplify the process by creating a web app that has a couple drop down menus to specify which script to run, then let me upload the .xls file, at which point the HTML file is automatically generated and a download link is created or the HTML file is spit out somehow.
Does anyone have any guidance as to how I should even begin this project?
I would suggest having a good read of the django docs, and probably working through the tutorials.
Django's documentation is very good.
If you just want to hack at the code you've got then probably read the following to get a very basic overview of some core django functionality -
url dispatcher
views
models
forms
templating
With your app, the url dispatcher will pass the request to a view which will use a template to render your excel document.
You want a form to handle your user parameters and a single view to render and process the form and also render the excel template.
I am building a small side project - a simple news site. I want to use the Django Admin for uploading articles and allow access to non-coders so as they can publish articles a la Wordpress or such. I have added some functionality to the admin, first trying out TinyMCE and Dojo rich text editors. However, these do not come with the ability to insert an image into an article from a file (just urls).
I really only want some light text formatting in the text area plus the ability to upload and insert images from the users's harddrive directly into the article. Is there a simple way to achieve this?
If you are already using django-tinymce, you can integrate django-filebrowser with it. See django-tinymce's documentation.
There is also a commercial choice which looks good, but I have never tested it.
I want to show the latest 8 images from a Flickr photostream using Django. I've had a good google and the only articles I can find focus on syncing the results with a database. I'd rather not do this if possible, I just want to show the images and nothing else.
http://code.djangoproject.com/wiki/FlickrIntegration This page has some adaptable code, but the library he uses seems to be offline now.
Does anyone have any examples of how I might integrate with a flickr stream without syncing the results?
Why can't you just use the flickr API from Python? There's probably python packages to do it. All you do is get the user's photostream info, map the photos to URLS:
http://www.flickr.com/services/api/flickr.people.getPhotos.html
Then your Django template just has an <img> tag with the right URL.
Edit: python packages listed on the flickr API page:
http://stuvel.eu/flickrapi

I made Flickr Pony for use Flickr with Django Storage API and more.
You'll only need an API KEY and launch this:
>>> from flickr_pony.storage import FlickrStorage
>>> storage = FlickrStorage(api_key="myApiKey")
>>> storage.listdir('140893176#N07')
