Module details

The collaboration project is divided into 6 modules for performing 5 different tasks as directed in Collaborative Communities section. A high level overview is depicted below:

Modules of collaboration project

The detail description for each of the modules are as follows:

  • dashboard - This module contains an Image Gallery in django where users can upload as many images and the result will be displayed into another page on clicking the create button.

    URL description for the module:

    http://127.0.0.1:8000/ - Base URL that contains button links to various modules of the application.

    http://127.0.0.1:8000/image_upload/ - URL to upload image files to the server.

    http://127.0.0.1:8000/image_list/ - URL is directed to when the form in /image_upload/ is submitted. This URL displays the images uploaded by user.

  • docviewer - This module contains a document upload section where document files can be uploaded and viewed in another page after the upload form is submitted.

    URL description for the module:

    http://127.0.0.1:8000/doc/doc_upload/ - URL to upload document files to server.

    http://127.0.0.1:8000/doc/doc_view/ - On submitting the form on /doc/doc_upload/ page, the uploaded files can be viewed in this URL.

  • slideviewer - This module contains a presentation upload section where presentation files can be uploaded and viewed in another link.

    URL description for the module:

    http://127.0.0.1:8000/slide/slide_upload/ - URL to upload presentation files to the server.

    http://127.0.0.1:8000/slide/slide_view/ - URL is triggered when the form on /slide/slide_upload/ is submitted. This URL displays each slides of the presentation in a file format. The contents of slides can only be viewed but not edited.

  • mediaAPI - This module contains a service that allows uploading image files to the server, updating specific image files based on their id , deleting image files rom the server and returning an API to access all images present in server database.

Note : This module does not interact with dashboard module in any way. The image files are also saved in a location different from that of dashboad and databases for each modules are separate.

URL description for the module:

http://127.0.0.1:8000/api/ - Form endpoint to upload image files for API usage.

http://127.0.0.1:8000/api/all_images/ - This endpoint returns a JSON formatted response containing data of all images stored in the database and their file path reference.

Sample JSON response:

[
  {
  "id": 3,
  "name": "Compass",
  "description": "This is a compass",
  "image": "media/ImageAPI/compass.jpg",
  "created_by": "Navigation dept"
  }
]

http://127.0.0.1:8000/api/images/?id=IMAGE_ID - This endpoint returns the JSON formatted response for a specific image(already existing in database). Invalid IDs will result in error.

Sample JSON response for IMAGE_ID = 3:

{
  "id": "3",
  "url": "http://127.0.0.1:8000/media/media/ImageAPI/compass.jpg"
}

http://127.0.0.1:8000/api/delete_image/?id=IMAGE_ID - Deletes image with the given IMAGE_ID as parameter both from the database and the file system and returns a JSON formatted response when the action is successfully performed.

Sample successful delete JSON response for IMAGE_ID = 5:

{
  "id": "5",
  "status": "deleted"
}

If no id parameter is passed to the URL http://127.0.0.1:8000/api/delete_image/, it results in a JSON formatted error response as:

{
  "error": "You need to pass in parameters"
}

http://127.0.0.1:8000/api/update_image - This endpoint results in a form page where the ID of an existing image in database can be entered and a new image can be uploaded and the image corresponding to the given ID will get updated with the newly updated image relative path in the database.

  • visualizations - This module holds a simple web application that uses D3.js to display data from json file.

    URL description for the module:

    http://127.0.0.1:8000/d3/ - D3.js uses the data stored in visualizations/static/json/data.json to create data points in the given URL.
    The data.json has been developed using the preprocessing module which is not a part of the django project but can be run independently to produce the data.json file.

Additional files and related discussion:

The django application requires some additional inclusions before running the application otherwise the application can run into errors.

  • media - Please create a media directory under the project folder. This directory will store all uploaded files from the user to this location and will use this location as reference to deliver files in JSON responses.

  • preprocessing - This directory isn't necessary for running the django application. This directory is used to prepare the data.json file used by the visualizations module. Please refer to further documentation under preprocessing directory here
