I made an iOS app that has my favorite quotes in it by category. I wanted to turn this into a dashboard widget that notifies me of a quote of the day. I've never made a dashboard widget and only read the hello world example on apple site.
Can anyone suggest a good tutorial or help me understand the following:
What is the best way to take my SQLite database of quotes and make it available through a dashboard widget?
Thank you.
Dashboard is, like, really old... it has the look of a technology that's barely clinging to life support.
But if you want to fool around with it anyway, the way to access SQLite from a widget would be to implement a native widget plug-in that uses the SQLite library, exposing methods that your widget JavaScript code can call to fetch the info you need.
Or, as you seem to have done, repackage the data in a different form that you can access more conveniently from widget JavaScript.
I ended up using NerdTools and implemented an awk script to pull a random quote from a text file on my computer. So this was solved a different way.

I am trying to create a web app that allows the user to browse a noSQL (Preferably MongoDB) database and perform some queries using a graphical interface. All the queries are written in the code and the user only needs to click links and/or enter strings (mostly to search for matches to be displayed in properly formatted tables). The app follows MVC model.
Up until now I used to write similar desktop apps using Java and JavaFX. I have no experience with other languages or frameworks (Aside from C and SDL), neither have I ever deployed anything on a server, and the assignment should be completed within 6 weeks (Three other students are working with me). And I have the three following questions:
Which language/framework is easiest to learn (considering I/we know Java/JavaFX)?
The answer to that would most probably be JavaScript*, which takes me to the next question:Is there any (practical) way that I would make it possible to write the app without having to learn HTML and CSS?
The third and last question, in case I write the View class in JS or Angular, can I write the Controller and Modal with Java (If we disregard complicated workarounds)? And do I deploy all three MVC classes/packages on the same server?
*I believe some would suggest we use GWT or Vaadin, and in this case I wonder if these frameworks have any quirks or limitations that would make it difficult for us as students to work with, be it when it comes to deployment (which is totally new for us) or the writing of the code itself.
Thanks a lot in advance.
Since nobody answered I am posting the best answer I could find so if anyone googles this subject could read it. At last we went with Java for backend running on Tomcat server and JS for front end. It turns out that HTML is very simple and JS is pretty similar to C/Java in syntax.
I am developing a cs-cart based website and my client wants to integrate Fishbowl into his website.
I have searched an add-on for it, but there is no one for me.
I have experience developed a simple add-on and, now I am going to build one add-on to integrate fishbowl.
Please guide me if you have solid experience on integrating fishbowl and cs-cart or another warehouse solution for cs-cart.
I don't understand why the fishbowl doesn't provide or developed the add-on for it.
Please help!
Thanks for reading!
Well, there are a few things to watch out for, and therefore a number of options.
Firstly, what does your client really want. Does he want the stock to be updated on the fly, or once a night? If the client wants to stock to be updated on the fly you will need to add some sort of post function for updating products to also execute your code. If your client wants it only once a night you could just get away by sending every product in the database (with your selected columns).
Secondly, try using object oriented code. If you are really into PHP you will know what I mean by this. Otherwise dont bother (or try learing PHP Object Oriented), though I must note that this can make your addon significantly faster.
Thirdly, use the provided dbquery function
If you have any more questions regarding this, feel free to ask.
I understand that this is a very broad question and could get flagged but I need inputs from experienced programmers and will ask it anyway. If there is another forum where I can post this question, please let me know.
Currently we manage all our application information in an Excel spreadsheet. At a high level it contains an app id, the server names that it is hosted on and the name of the environment. The Excel spreadsheet has become too large and I am looking to build a simple application for it.
Ideally, I would like to write this app on Windows as everyone uses Windows but dont know how to go about it in Windows. I then thought of using MySQL and PHP or Perl (CGI) to build this but thought of exploring something new. I read about Joomla and a few other CMS products which make it very easy to build websites but am not sure whether these allows me to pull information from a database.
I am seeking inputs on what would be a good way to way to build this application.
Use Joomla! CMS is a good choice and to pull data from database you may use webservice calls. So, you will able to create a CMS website using joomla and will able to pull data easily from database with the help of webservice.
You can get webservice support in joomla by installing component redCORE in joomla.

I think Joomla is a great option to handle big loads of information. If you already know PHP and don't need to reinvent the wheel, it's cool. The way of handling data in Joomla is using Components.
If you want to try, it would be as easy as installing a local copy of Joomla, building the field structure on component-creator.com installing it and importing the data inside the component using phpmyadmin.
I would like to build a chrome extension (CE) that pulls data from a ruby db for a specific user. So, in a basic example, if an user submits their favorite color as 'red' and sport as 'tennis' into the db from the core website, when they click the CE, 'red' and 'tennis' will show up no matter where they are on the internet.
Any guidance on how to build something like this? Seems quite simple but am not sure how the CE files fit in with the ruby folder framework.
Also, is it possible to write to a ruby database from a popped out CE? i.e. - submitting 'red' and 'tennis' from the CE to the ruby database to go along with the previous example. Any guidance?
Cheers
This is a very general question so it sounds like you will need to learn a lot. Which can be a good thing :)
Here are the general steps you need:
Look into building an API for your ruby application. This will allow you to get data from your database. For example, you can
make an app where you go to http://yoursite.com/api/favorites and that will return a list of all favorites as JSON. Then in your Chrome Extension you can parse the JSON and display the results to the user. You will probably want to do this using an ajax call (see jquery.ajax for an easy way to use ajax).
Assuming you want user accounts, your user will need to be logged in. Then you can use your user's cookies to verify that they are logged in and show them custom info. i.e. going to http://yoursite.com/api/favorites will just show the favorites for that user, not for everyone.
Finally, submitting things to the database...you can have another route where users can send stuff. For example, if you go to http://yoursite.com/api/favorites/add?color=red then it will add the color red to that user's favorites. You will need to write all the logic for adding stuff to the database...again, it might help you to go through a rails tutorial and then look at building an API.
Related to #3, look into RESTful APIs. A good convention is that if you issue a GET request, you're asking for data, but if you issue a POST request, you are adding data (in your case, creating a new favorite).
Finally, for terminology: it's not a "ruby" database, it's just a database. You can access a database using almost any language, and it sounds like you are accessing it using ruby right now :)
If you only need to store data for one machine browsing anywhere online, chrome has a storage api that would work great.
If you do need a ruby server, I would recommend looking at sinatra.
I am developing a small web application using Ruby, Sinatra & HAML.
The scenario I am struggling with at the moment is something that I used to solve in PHP using Ajax and Javascript, and am not sure how to best go about doing it in Ruby (what the best practice would be, if there is a more optimized way of approaching this).
I have a screen as follows:
What I wish to happen is that when a user clicks on one of the buttons (for example Show most popular), the system calls a function which queries the database to get the relevant records and re-populates the 'Entries' box with the appropriate records. I want to do this without the rest of the page re-loading or anything else being effected, just the 'Entries' box. Bonus - If I can show a little "LOADING" spiral while the data is being fetched.
My research led me to gem known as "typhoeus" which I found to be really great, but am not sure if it applies in this scenario (or how to implement it if it does).
Any kind of help would be greatly appreciated.
Much obliged.
It seems like pjax is what you would be looking for.

The author uses Sinatra in his example app. Though he does use erb, I am sure that it wouldn't cause any problems if you switched the template engine to haml
