django-template-docx

Django-Template-Docx provide all the necessities to easily include docx merging capabilities to any Django project.

Main functionnalities:

• Easy data definition for developpers
• Autogenerated documentations for end users
• complete set of views and templates for end users to upload templates and download them merged

Install

pip install django-docx-template

Then update your settings:

INSTALLED_APPS = [
    ...
    "django_docx_template",
    ...
]

to finish, wire urls:

# config/urls.py
from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path("admin/", admin.site.urls),
    path("docx/", include("django_docx_template.urls")),
]

Usage

Create a DataSource

First you'll need to create a source of data:

# my_app/data_sources.py
from django_docx_template.data_sources import DataSource

# let's imagine you have a Model Person
from .models import Person


class PersonSource(data_sources.DataSource):
    # properties
    label = "Data source for Person"
    model = Person
    url_args = {"pk": "int"}
    # fields that will be used for merging
    first_name = data_sources.Field(examples=["Pierre", "Paul"])
    last_name = data_sources.Field(examples=["Smith", "Dupont"])
    size = data_sources.Field(examples=["180", "190"])
    favorite_color = data_sources.Field(source="color__label", examples=["red", "blue"])

then you need to add the data source to your settings:

# config/settings.py
...
DJANGO_DOCX_TEMPLATE = {
    "data_sources":[
        "my_app.data_sources.PersonDataSource",
    ]
}

Now your end users can access :

• docx/sources/ to explore data sources and related documentation
• docx/templates/ to browse and upload new templates
• docx/templates/detail/ to test downloading document

For example, to download a document with slug="identity" and wired to the data source previously built, the url would be /docx/template/detail/identity/123 (where 123 is a person_id).

Ideas for future improvements

• add documentations
• Make a ModelDataSource that really autogenerated doc from field type and help argument
• Then make a mixin that turn a Model into DataSource (would be awesome)
• Add managed command to help generate DataSource
• Customize admin views
• Add options to make DocxTemplates invisible or undeletable to wire them in other part of the app without risking enduser changing it
• Add protection mechanisms to provided views to restrict them to a particular set of users or restrict template list
• Add check mechanisms to valid docx document on upload (example a tag in the document that is not in the datasource should raise a warning because it will never be populated)
