Courses

An extension to GoBlender that allows for delivery of video based online courses.

Core Functionality

• Video lectures
• Create as many courses as needed
• Static page lectures
• Drag & drop page creation
• Track student progress
• All for submission of assignments
• Allow for grading of assignments
• Integration with MS Teams

Setup

First, install GoBlender.

All client specific code lives in ./client/clienthandlers, and is its own git repository. When working in JetBrains Goland, you must create (or clone) a git repository in this location, and then add the directory in Preferences -> Version Control.

Updating on server

Change update.sh in GoBlender root folder so as to enable git pull of client:

# uncomment if using custom client code
#cd ./client/clienthandlers
#git pull
#cd ../..

# run migrations for pg
# soda migrate -c ../../migrations-pg/database.yml

After changing, it should look like this (assuming you want to run postgres migrations):

# uncomment if using custom client code
cd ./client/clienthandlers
git pull
cd ../..

# run migrations for pg
soda migrate -c ../../migrations-pg/database.yml

#run client migrations for mariadb
# soda migrate -c ../../database.yml

Using custom templates

Inside of clientviews there are two folders: public and private. If you wish to use the base templates from GoBlender to create templates, do it like this:

For public pages:

{{template "base" .}}

{{define "title"}}Some title{{end}}

{{define "body"}}
    <p>Put whatever you want here</p>
{{end}}

For admin pages:

{{template "admin-base" .}}

{{define "title"}}Some Title - vMaintain Admin{{end}}

{{define "admin-title"}}Some title{{end}}
{{define "content-title"}}Some title{{end}}

{{define "content"}}
    <p>Some content</p>
{{end}}

Note

You can override anything in the base templates, or specific pages/partials, by putting a file in client/clientviews/public, client/clientviews/public/partials, client/clientviews/admin, or client/clientviews/admin/partials.

Client Specific Migrations

Migrations live in client/migrations. To run them, add the -c flag to soda, e.g.:

To generate Postgres migrations:

cd client/clienthandlers
soda -c ../../migrations-pg/database.yml generate fizz SomeMigrationName

To run Postgres migrations:

cd client/clienthandlers
soda -c ../../migrations-pg/database.yml migrate

To generate MariaDB/MySQL migrations:

cd client/clienthandlers
soda -c ../../database.yml generate fizz SomeMigration

To run MariaDB/MySQL migrations:

cd client/clienthandlers
soda -c ../../database.yml migrate

Middleware

Add custom middleware to ./client/clienthandlers/client-middleware.go, e.g.:

// SomeMiddleware is sample middleware
func SomeMiddleware(next http.Handler) http.Handler {
    return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
        ok := true
        // perform some logic to set ok
        
        if ok {
            next.ServeHTTP(w, r)
        } else {
            helpers.ClientError(w, http.StatusUnauthorized)
        }
    })
}
