Prestashop 1.7.4.4 can't see my module

[salvio78]

I follow the 1.7 developer guide at:

https://devdocs.prestashop.com/1.7/modules/

I create a helloworld module directory and a helloworld.php

But I can't see it in backoffice at all.

Maybe I have to do some more steps, can anyone help me?

helloworld.zip

Did you search it in second tab "Selection" of Modules and Services?

The fact is that if I install it from zip there is no problem, otherwise I can't see it.

I've been at Prestashop for about a month now, and it took me three days to figure this out - I _THINK_ it's because somewhere along the Upload process an entry gets created in the `authorization_role` table followed by the `access` table.   Without these entries the Back Office TABS and/or MODULES you place in the directory cannot be seen. 

For 'MyCustomBackEndModule', I had to add via SQL INSERT to the `authorization_role` table:

ROLE_MOD_MODULE_MYBACKENDCONTROLLER_DELETE

ROLE_MOD_MODULE_MYBACKENDCONTROLLER_READ

ROLE_MOD_MODULE_MYBACKENDCONTROLLER_UPDATE

ROLE_MOD_MODULE_MYBACKENDCONTROLLER_CREATE

And because I had a TAB installed, I also had to add 

ROLE_MOD_TAB_MYBACKENDCONTROLLER_DELETE

ROLE_MOD_TAB_MYBACKENDCONTROLLER_READ

ROLE_MOD_TAB_MYBACKENDCONTROLLER_UPDATE

ROLE_MOD_TAB_MYBACKENDCONTROLLER_CREATE

Then I took the IDs that were generated from these commands above and also had to find the proper profile id for the administrator ( probably 1 ) and SQL INSERT them into the `access` table.

Of course, all of the permissions are dependent on what kind of access you want.  Administrator should probably have all the access, but if your module has a front end editing component, you may want to limit the `access` for other profile ids
