Every tutorial and guide show I need another framework such as Express, Angular, Sails, or Koa to connect with MongoDB.
Do I need to learn how to write Middleware, Adapters, and more to get MongoDB to work with EmberJS?
I'm pretty new, and I just finished a simple to-do and web scraping apps. I want to learn how to store it like how I can just write python script, process data, connect to postgresql, save data to the database server.
Can you provide a link to the right source, a step by step process, or tools to research that can help anyone in my position now and in the future learn how to make EmberJS and MongoDB work together without going in circles?
I use nodejs, emberjs, mongodb hosted on heroku.

I have a HTA tool that connects to oracle database. It's created using HTML,Javascript and oracle as backend.
Javascript connects to oracle database using OLEDB drive. It pulls data and create dynamic rows.
Tool is working but now am planning to convert it as Web Application.
Being a DBA , am not that much familiar with Java and i thought i will explore options in Python.
I have recently done a automation using Python and Selenium. So yes , i know bit of Python. But i have no idea about website using python.
I also don't want to change lot of code. I want javascript to do all the dynamic front-end stuffs.
All i need is interface that can connect to oracle database and pull the information and pass it to javascript function.
Can someone please guide to how to start with.
Thanks.
I don't know Python but if you don't want to change a lot of code, you may consider PHP. It's made to generate HTML code dynamicaly.
It is dangerous to connect to your DB directly by using javascript. Every user can read the JS code in the page and event modify it(sending every value they want).
PHP is executed on the server, it mean that you can check and validate the received value before risking to corupt your DB.
That's why a PHP page between the JS and the DB is better. Python should be secure too but I think it's easier to use PHP because it's open source and well documented.
I wish you a good continuation!
I am new to cloudantdb and django. Is there any way to integrate cloudantdb with danjgo framework. Is it possible to connect cloudant with django?
As you may be aware, Cloudant is built on Apache CouchDB, so if you can't find references for Cloudant, it's usually worth also searching for CouchDB. I don't really use Django, but a quick search throws up the following references:
http://leok.me/2013/05/02/what-you-need-to-know-couchdb-django/
https://lethain.com/an-introduction-to-using-couchdb-with-django/
http://eflorenzano.com/blog/2008/11/10/using-couchdb-django/
https://djangopackages.org/grids/g/couchdb/
Most if not all solutions on the web are very outdated.
The solution used by IBM in a capstone project on Coursera was:
Use SQLite backend in your Django app
Create Cloud Functions for communicating with Cloudant
Create REST API definitions in your Django app that utilize the Cloud Functions to communicate with Cloudant
I don't know if it's the best solution, but it works. I do feel like SQLite is redundant at this point but without it, I couldn't get the app to work.
Is it reliable to build desktop applications using web frameworks like Django?
The idea is to
build the interface with HTML, CSS, and JavaScript
use Python and Django for backend operations (calculations, storage and databases, etc)
and then run a server locally so that
the interaction with the application is done through the browser
other local devices can access the application by connecting to the device on which the server is running.
If that is possible and yields a reliable experience, then
is the development server that comes with Django enough? If no, what servers are most suitable for our purpose? Is Nginx good for example?
what database should be used? PostgreSQL, MySQL, etc? The app will need to store a large number of entries.
I've never done this, but I can't see why not. You can use the Django REST Framework to create an API that your desktop application can talk to, in exactly the same way as you might with a JavaScript single page app.
But no, you should not use the dev server for production, even in a limited scenario like this. Apache/mod_wsgi or nginx/gunicorn are simple to set up and deploy.
For the database, it makes no difference. The Django core devs prefer postgres, but you should use whatever you are comfortable with.
You are asking for a webApp, so yes you can. Is not use the Django server, instead is very common use nginx for Django, and the best database is postgres for Django.
If you want to pass your project like a desktop app is better use Django server and SQLite for avoid create a new database server.
Database
I find this answer explaining why is postgres better for Django
I have made a web-app using django framework and stored it on heroku.
How can i combine phonegap so that I will be able to create both iOS and Android application that will simply load my hosted website?
I'm having an hard time knowing how to combine both technologies (django and phonegap) together, because phonegap requires the "index.html" and i dont know how to make it navigate to my main page.
And i dont know what "Procfile" to use in order that the heroku server will know how to react both.
I have seen somthing involves rest API for django. I found it hard to understand why should i add it for my website...
A tutorial would also be great !!
Integrating phonegap and django is a pretty broad topic covered here and in this tutorial.
For setting up multiple stacks on the same heroku app, you will probably want to use buildpack-multi.
I am working on creating a dashboard which would access Redmine project data. This dashboard will be a consolidation of project data (delivery date, manager, start date, total issues, open issues, closed issues, bug count etc.) for all projects in the Redmine database.
Any ideas on how to do this? An SQL query to achieve this would be a good start. I have Redmine setup on my local system and can access the Redmine database.
I plan on creating an HTML5 .Net based web application. Once I figure out the queries to be used, I would write an IIS (or REST) service to fetch the desired data from the Redmine production database.
Any help/pointers would be deeply appreciated.

You have basically three options:
use the REST API
develop a redmine plug-in
do some custom SQL stuff
REST API
The best you could do is to use the redmine REST API. Using it, you can fetch the data directly from redmine without any SQL queries or manipulating the server. It should even work when the redmine server is updated.
Redmine Plug-in
The next best thing is probably to develop a redmine plug-in. Your plug-in can access redmine classes (Project, User, etc.). For example, you could do something like Projects.all.map {|p| [p.id, p.identifier]} to get the id and identifier of all projects in an array. This approach is way more powerful than using the REST API, but you have to modify the redmine server (install and maintain your plug-in). A plug-in is probably more fragile when redmine changes internal structures, than the REST API.
Custom SQL stuff
I do not recommend developing custom SQL solutions, but it is an option. Such a solution is harder to develop, more fragile, harder to set up, but might offer better performance.
You can see the the redmine database structure listed in db/schema.rb. Having the right schema, you could develop your custom SQL queries and return them to your dashboard.
Think about security
Apart from the usual security stuff (which you should consider too :)), remember that redmine has a rich permission system. Consider which object you make (publicly) available. This is most important for the last two options. When using the plug-in approach, you should have a look at the User#allowed_to method.
With the little information I have about your requirements, I have the feeling that you should go for the REST API.
