moodler's Issues

Persist connection within package NS

Cache non-base tables.

In order to work with third party modules.

Make database table prefix configurable

The default table prefix is mdl_. As some Moodle installations use a different prefix it would be nice to have this value configurable via config.yml.

Declare package global variables

Use metaprogramming to declare column names in the package and avoid NOTE on check

Can´t figure out the config file part

Hi the example function does not open.
Can´t figure out how to edit it/write it
will love to test this package instead of having to use the API and will be very grateful for your input
thanks...

Download course content

Hello,

I am working on a research project which requires me to interact with moodle via R and I had a few questions regarding the functions of the package. Is there an option/way to access the course content through the package? Also, is it possible for a Moodle that is not local to the system to interact with this package via MoodleAPI?

Any information regarding the same is much appreciated as there is limited support on several platforms regarding this.

Regards,
Aarathy

Query not preparing correctly

When I run

test_courses <- mdl_courses(con = mdl_get_connection(use_cache = FALSE))

I receive the error

Error: Failed to prepare query: ERROR:  relation "courses" does not exist
LINE 2: FROM "courses" AS "q01"
             ^

My Moodle database runs off of Postgres, and when I run the command

test <- dplyr::tbl(mdl_con, "courses")

I get the same error

Consistently return tbl_lazy obejct from functions

As per comment made in #9 by @alex-ondrus

PostgreSQL support?

When running
mdl_con <- mdl_get_connection(use_cache = FALSE)
I receive the following error:
Error: Failed to connect: Lost connection to server at 'handshake: reading initial communication packet', system error: 2
We have set up the config.yml file as described in the setup vignette and are able to connect to the database using other tools (pgAdmin III) with the same settings, so I don't think it is a connection issue. After doing some googling it looks like it may be that the package is expecting a MySQL connection. Our institute runs their Moodle database on PostgreSQL.

Does moodleR support connections to Moodle databases running PostgreSQL?

Add set_default_connection

Change Port

Hello,
I´m currently working on a project where I have to connect a RStudio-server with a Moodle-database. I have created the config.yml with the database information but MoodleR seems to ignore the port-specification in the config file so the connection fails (our database admin told me, that MoodleR tries to connect via standard 3306 instead of the specified port 3308).
Is there any other way to force MoodleR to use the correct port?
Thank you in advance!

My config.yml looks like this:
default:
moodleR:
user: "XXX"
password: "XXX"
dbname: "XXX"
host: "XXX"
port: 3308
