So, I know how to make a module with cookiecutter, but how do i really install it? I mean should I make them in /home/pathos/path/d/lib/python3.12/site-packages/trytond/modules here? And then I run the admin-tryton stuff?
And theres another question. I have several modules I want to try that I donβt install with pip, how do I install it without having a conflict? Thank you so much.

Have a look at the [module tutorial](https://docs.tryton.org/latest/server/tutorial/module/setup.html).
There most of your questions are answered.

Edit: Recommended installation method depends on what you are trying to do.
While that can work, it is strongly discouraged.
For testing and development you will find the following in the module tutorial:
`python3 -m pip install --use-pep517 --editable opportunity`
> [@mahija](#):
>
> And then I run the admin-tryton stuff?
After you have installed/added a module you need to run:
`trytond-admin -c trytond.conf -d databasename -m`.
`-m` updates the module list.
After adding or modifying it is necessary to restart the server so that the new code can be read, unless you are using `trytond --dev`.

Official tryton modules are designed to not conflict, but you do need to mind other module dependencies and external python dependencies.

Just to be sure, suppose I already make a whole module in trytond/modules, then in the folder i run` python3 -m pip install --use-pep517 --editable my_module_name`?
and another question can i modify official tryton modules?? and if i can edit my module/official module should i run this again` trytond-admin -c trytond.conf -d database name -m`? Thank you so much for answering. π₯π₯π₯π₯π₯π₯

Either you install using the above command, or you put the directory containing the module in the trytond/modules directory, not both.

I had the same idea when I started out using tryton.
You CAN, but it will become a nightmare to maintain.
Tryton modules are designed to be extended, so you can extend or override most aspects of a module without actually changing the original module. This is also covered in the module tutorial.

I _strongly_ suggest you to not do this. This is mixing installation and development. You will run into troubles more quickly than you think and you will end in a nightmare.
I suggest to:
- use a project directory per module
- install trytond in a virtual environment
- activate the virtual environment
- install your module in the virtual environment (using `pip` like @dotbit has shown)
- If your module depends on other custom modules, consider using a `requirements.txt` file to install these prior to installing your module
- For modifying official modules: Use an own custom module containing the modifications.

Thank you.
I have made an env for this and i installed some official modules in that env. The modules are installed in myenv/lib/python/site-packages/trytond/modules/
In modulesβ path there are gnuhealth modules and official modules. Since I want to develope my own modules should I make my custom module in that exact path? Or I could create another path for my custom modules?

I suggest to use one separate path for every of your custom modules like this
```auto
.
βββ my_module_1
β βββ requirements.txt
β βββ setup.py
β βββ tryton.cfg
β βββ β¦

I get the gist of these, thank you. So i should run `python3 -m pip install --use-pep517 --editable my_module_name` with every name? I could not do this bundle?
P.S: I already did what you told: and after i run trytond-admin -c trytond.conf -d my\_database -m this errror shown: OSError: File not found : /home/username/.virtualenvs/folder\_name/lib/python3.10/site-packages/trytond/modules/absensi/tryton.cfg

Yes, every module needs to be installed.
> [@mahija](#):

What does `ls /home/username/.virtualenvs/folder_name/lib/python3.10/site-packages/trytond/modules/absensi/tryton.cfg` result in?
BTW, your venv needs to be activated before you install your module, so that you are installing the module inside your venv.

This: `ls /home/username/.virtualenvs/folder_name/lib/python3.10/site-packages/trytond/modules/absensi/tryton.cfg`
Result in: `ls: cannot access '/home/username/.virtualenvs/folder_name/lib/python3.10/site-packages/trytond/modules/absensi/tryton.cfg': No such file or directory`
But that was because absensi is a custom module, and why they would read a custom in `trytond/modules/`??
note: my venv is active

Every module needs to have a tryton.cfg file. It does not matter if it is custom or official.
See [Anatomy of a module β Tryton server](https://docs.tryton.org/latest/server/tutorial/module/anatomy.html)
When trytond starts it reads all the installed modules, even not activated ones.
If there is an error or something missing trytond will not start.
If you put `absensi` in your modules directory manually and you are not using it I recommend deleting it.

Of course I have trytond.cfg inside `absensi`. But somehow it could not read the trytond.cfg
because this path: `/home/username/.virtualenvs/folder_name/lib/python3.10/site-packages/trytond/modules/absensi/tryton.cfg` is not the path of absensi modules.
This is my structure file, absensi is my module:

It seems that I have confused you with the trytond/modules directory, and for that I apologize.
There are multiple entry-points to a module depending on installation method, one of which is the module directory inside trytond directory.

It should be tryton.cfg.
> [@mahija](#):

Perhaps an old version of the module which is no longer there is registered in the database.
Are you using an old database, or starting a new one?
I would recommend checking that the module is installed using `pip list` and starting with a new database.

This error message is often misleading. This often means that your module fails to import (due to an error in your module). Just add a `raise` in front of [line 77 in trytond/tools/misc.py](https://foss.heptapod.net/tryton/tryton/-/blob/branch/7.0/trytond/trytond/tools/misc.py?ref_type=heads#L77). nly use this in your development environment!

Thank you @htgoebel, I will keep that in mind. That was beyond my knowledge.
@mahija The technique I use to avoid such errors is to make really small steps, then test and when you get an error you know which step produced the error.

I assume the link you gave me was trytond 7.2. I forgot to mention it was trytond 6.0 and the line in misc.py is a bit differen(that already bin raised)t:

Oh, you are still on 6.0. AFAIU you are using GnuHealth and assume GnuHealth is still on 6.0. Otherwise Iβs strongly suggest to start new projects with the current TLS version.
In 6.0 the behavior was quite different and even worse. Since there are many possibilities why this can fail, I suggest to add this before line 42 and step through the code.
```auto
if module_name == 'absensi': breakpoint()
```
