A Django Management Command for displaying details about your project's models.
**Warning**: This project is still very new. Expect to see proper testing and an example app demonstrating the command soon.
When working with large projects or when returning to a code base after some time away, it can be challenging to remember all of the fields and methods associated with your models. This command makes it easy to see:
- basic details about each model, such as the database table name, the file and line number where the model is located, etc.
- what fields are available
- how each field is referred to in queries (direct/reverse relations)
- each field’s class
- each field’s representation type in the database
- what methods are available
- method signatures
- method location and line number
- etc
This package takes the original [`list_model_info`](https://django-extensions.readthedocs.io/en/latest/list_model_info.html) command I wrote for django-extensions to a whole new level. I attempted to simplify some aspects of configuration, while increasing the overall amount of information provided.
The beautiful interface is thanks to [`rich`](https://github.com/willmcgugan/rich/)
## Documentation
The full documentation will (soon) be at <https://django-model-info.readthedocs.io>.
## Quickstart
Install django-model-info:
pip install django-model-info
Add it to your \`INSTALLED_APPS\`:
``` python
INSTALLED_APPS = (
...
'django_model_info.apps.DjangoModelInfoConfig',
...
)
```
Run the management command:
``` bash
>>> python manage.py model_info
```
An example of the resulting output can be seen [here](https://htmlpreview.github.io/?https://github.com/jacklinke/django-model-info/blob/master/example-output.html). This example shows the most verbose (level 3) details for a single model.
## Features
You can customize the output in a number of ways.
### Verbosity
Verbosity levels adjust the amount of information displayed to the console, and is set with the `-v` or `--verbosity` argument.
- 0 - Model names only - Convenient when you just need a list of all your project's models in one place
- 1 - Model names, field names, and non-dunder/common model method names
- 2 - Model names, field names & details, and non-dunder/common model method names & details
- 3 - Model names, field names & details, and all model method names & full details
Note: The default verbosity in `django-model-info` is **2**
From the command-line:
``` bash
>>> python manage.py model_info --v 0
>>> python manage.py model_info --verbosity 0
```
You can specify a different default verbosity value in your settings file.
``` python
MODEL_INFO_VERBOSITY = 1
```
### Filter
By default, all models within your project are processed and displayed. For large projects, this can result in an enormous output. If you want to limit output to a subset of models, you can use the `-f` or `--filter` argument, providing one or more of the following:
- Models, in the form of `appname.Model`
- Apps, in the form of `appname`
If Django is unable to find provided entries, a message will be written to the console, and the remaining models will be processed and displayed.
From the command-line, here is an example that processes all models in the `myapp` and `auth` apps, and also the `otherapp.SpecificModel` model:
``` bash
>>> python manage.py model_info --f myapp otherapp.SpecificModel auth
>>> python manage.py model_info --filter myapp otherapp.SpecificModel auth
```
You can specify a list of default apps and models to process in your settings file. Using the command-line example names above:
``` python
MODEL_INFO_FILTER = ["myapp", "otherapp.SpecificModel", "auth"]
```
### Export
`django-model-info` can optionally export the console output to an html or text file. The extension of the provided filename must be `.txt`, `.htm`, or `.html`.
``` bash
>>> python manage.py model_info -e myfilename.html
>>> python manage.py model_info --export myfilename.html
```
