Reflections on Milestone 4


Updates we completed for the final milestone of our open source application

  • Improved authorization awareness of the application.
    • Updated authorization to prevent unauthorized users from editing or deleting routines or magicians.
    • Displayed navigation elements based on your logged-in state and whether you are the owner of an item or not.
  • Added the Set Notes feature
    • A Magician may input desired information about a Set, and then get an analysis of the Routines they’ve chosen for the Set.
  • Resolved the https issues to the best of our ability with Heroku.
  • Used FontAwesome icons for placeholder images in newly created Profiles, Routines, and Materials that do not have uploaded images.
  • Fixed image upload issue when deployed on Heroku.
  • Evolutions were not being applied in Heroku.
  • Cleaned up dead branches.

Feedback on Milestone 3

The PWM team got feedback from our professor after we demoed Milestone 3. Our professor gave us the following feedback:

  • Probably not good for unlogged-in users to edit/delete all content. 
  • Maybe only allow “creator” of content to be able to delete it?
  • Implement first pass at Magic Checkstyle.

Plan of Attack for Milestone 4

  • Patrick noticed that I had not normalized the imageId field that defines the “one to one” relationship between the Magician’s profile image and the Image entity I had created in the code to allow the user to upload images. After looking into the problem I noticed that I had also neglected to establish the one to one relationship in the Routines and Materials imageIds as well. I added this bug as an issue on Github. I focused on updating the image upload code I had written.
  • Mark worked on implementing the Set Checker feature for our application.
  • And Patrick worked on finalizing the User Authentication issues we had encountered in our demo of Milestone 3.

We met on Skype for a few hours and each worked on the issues that had been assigned to us. Our longest stretch of programming was around 3 hours. Here’s a screenshot I took while I was running the tests on the code.

Github Issues I fixed

Issue #189: Set up default images for Profile, Routines, and Materials:

Screen Shot 2015-05-13 at 3.27.49 PM

I created a new branch called fixImageUploads-1 off of the Milestone 3 branch and started updating,, and to note the “one to one” relationship between the entities. Once I had updated the java files, I spoke with Mark and learned that we had created a new branch called Milestone-4. The branch I had merged off of was out of date.

I abandoned the fixImageUploads-1 branch and created a new branch off of the Milestone-4 branch and redid my corrections.

Then I noticed that now I had 2 branches with the same name. I did an easy fix and created a new branch off of fixImageUploads-1 called fixImageUploads-2. Then I spoke with Patrick and gave him the name of the correct branch name and he merged it with the master branch.

Issue #209: Images are referred to by their ids instead of a database relation

Screen Shot 2015-05-13 at 1.26.32 PM

There was an issue with images not being associated with the correct Magician/Routine/Material. When we checked the edit and view pages for Magician, Routine, and Material, the pages were querying the database for images that were not there. We had added Magicians, Routines, and Materials to the in-memory database. Now when we were loading the view or edit pages, they were looking for images that had not been ported to the Postgres database.

I updated the code to check for the imageId associated with each Magician, Routine, and Material to validate the imageId. If the imageId was not a valid number the code did not attempt to load the image.

Issue #211: Image Uploads do not work on Heroku

Screen Shot 2015-05-13 at 3.27.53 PM

Another issue that came up with the addition of the image uploads was located when Mark and Patrick ran Mark’s Chromium tests on the codebase. I fixed this issue by removing all tests that referred to deleting Magicians, Routines, and Materials.

This was an easy fix that involved opening the code in IntelliJ and running a search all files operation with the keyboard shortcut Shift+Command+f. I searched for the keyword “delete” and commented all references to methods to delete the Magician, Routine, or Materials in the Postgres database.

We collectively decided to leave the delete code in to allow for future updates that will allow the site administrators to delete Magicians, Routines, and Materials in the future once the Site Admin accounts can be created.

Issue #223: Fails tests in Milestone-4

Screen Shot 2015-05-13 at 1.26.30 PM

Once I had removed all references to delete Magicians, Routines, and Materials in PWN, the tests started to fail. 5 out of 15 tests were failing. This was a good thing. This allowed me to dig into the Chromium tests that Mark had written to remove the test code that was testing against the Postgres database.

Once I had removed the tests that checked the delete functions the tests all passed. I confidently merged my changes into the Milestone-4 branch.

Created Set Notes wiki page

I created a wiki page for the Set Notes that explains how to use the feature on our site. In order to accomplish this I reviewed the Set Notes Design in the Developer Guide and updated it to show what was actually implemented in the code. I also took screenshots on desktop and mobile versions of the site and added them to the docs/images folder on the master branch of our code. I pushed the repo and linked the images in the Set Notes to the images in the code.

PlayWithMagic – Reflections on Milestone 3

homePageDesktop fosters an online community around an online tool that allows amateur magicians to post renditions of well-known routines and get feedback from their peers as well as professionals. also allows magicians to post their routines as sets. Once the set has been posted, will automatically process the saved set and suggest improvements to refine the set based on the venue, type of magic performed, and duration of the set. also allows other magicians in the community to comment on the sets that magicians have created to suggest additions and refinements to the sets that have been created by amateur magicians on the website.

This milestone brings together Authentication, Tests, and Image Uploads. We are edging closer and closer to a project that can be distributed to other developers to update and refine our initial product.

  • The deployed instance can be found at (as of 5/5/2015 at 8:54pm we are working on a few issues with our last merge)
  • can be accessed on Github here.

Project management is the process and activity of planning, organizing, motivating, and controlling resources, procedures and protocols to achieve specific goals in scientific or daily problems.

The primary challenge of project management is to achieve all of the project goals and objectives while honoring the preconceived constraints. The primary constraints are scope, time, quality and budget. The secondary — and more ambitious — challenge is to optimize the allocation of necessary inputs and integrate them to meet pre-defined objectives.


The time constraint on this project was palpable. Our frequent meetings on Skype have, by far, been the best way the team has communicated. Being able to meet on Skype has really allowed us to keep the momentum going.

Here’s a video I put together of our tests running on

I really would have liked to be able to code while we are all coding online but I found that I do my best coding when I have complete silence (or classical music).

Working with talented and driven developers is making me a better developer. Having standing weekly meetings has worked well. I never feel like we’re at a loss for which direction to go. When I have a question about the tools  we are using or the code that we are building I am confident that one of my collaborators will have an answer.

Having finally fixed the bug that didn’t attribute my commits, my commits are finally showing up in the Github graph so my contributions are noted.

In the final milestone I’d like to see our “secret sauce” (Set Style Checker) implemented and providing constructive feedback to our community of amateur magicians.

At this point I feel like we’ve built a beautiful building, but it’s empty inside. It’s got air conditioning, it’s locked down with round-the-clock security, and it has a fresh coat of paint. But we are still waiting for the tenants to move in and start building cool things, having cool experiences, making friends, networking, and stepping up their magical game.
