djangotextsplitter 1.0.4

This package allows the pdftextsplitter engine to communicate with a Django-database

djangotextsplitter

This package is meant as a django-extension for the pdftextsplitter package. As such, the pdftextsplitter package should be installed before this package.

This django-extension provides an out-of-the-box django-app with database models for the python-classes in pdftextsplitter. As such, it becomes possible to store the results of the pdftextsplitter package in the django database.

The django-application in this package does not contain any views, urls, templates, static files or any other functionality. Only database models (including admin-registration) and load/write functions. These models and load/write functions can then be used in other django applications, together with the pdftextsplitter engine.

Installation works like: pip install djangopdftextsplitter

List of database models

The database models in this application are:

• textpart (corresponds to the textpart-class from the pdftextsplitter-package)
• fontregion (corresponds to the fonregion-class from the pdftextsplitter-package)
• lineregion (corresponds to the lineregion-class from the pdftextsplitter-package)
• readingline (needed to store certain information, but does not have an equivalent in the pdftextsplitter-package)
• readinghistogram (needed to store certain information, but does not have an equivalent in the pdftextsplitter-package)
• title (corresponds to the title-class from the pdftextsplitter-package)
• body (corresponds to the body-class from the pdftextsplitter-package)
• footer (corresponds to the footer-class from the pdftextsplitter-package)
• headlines (corresponds to the headlines-class from the pdftextsplitter-package)
• headlines_hierarchy (needed to store certain information, but does not have an equivalent in the pdftextsplitter-package)
• enumeration (corresponds to the enumeration-class from the pdftextsplitter-package)
• enumeration_hierarchy (needed to store certain information, but does not have an equivalent in the pdftextsplitter-package)
• textsplitter (corresponds to the textsplitter-class from the pdftextsplitter-package)
• native_toc_element (corresponds to the native_toc_element-class from the pdftextsplitter-package)
• breakdown_decision (needed to store certain information, but does not have an equivalent in the pdftextsplitter-package)
• textalinea (corresponds to the textalinea-class from the pdftextsplitter-package)

Getting started

Within a django-environment (if the djangotextsplitter is installed in the virtual environment and registered in the django), one can simpy have access to the model by calling
from djangotextsplitter import textsplitter as db_textsplitter
We recommend using the 'as db_' to distinguish django database models from base classes in the pdftextsplitter-package.
Loading/writing operations can be accessed with:
from djangotextsplitter import load_textsplitter
Each model that has an associated class in pdftextsplitter, has a load-function, a newwrite-function, an overwrite-function and a delete-function.
They can be called as:
from pdftextsplitter import textsplitter
from djangotextsplitter import textsplitter as db_textsplitter
mysplitter = load_textsplitter(31) # 31 is database primary key; in django the pk
db_splitter = newwrite_textsplitter(mysplitter) # No need for a key here, as it is appended to the list
db_splitter = overwrite_textsplitter(31,mysplitter) # 31 is database primary key; in django the pk
delete_textsplitter(31) # 31 is database primary key; in django the pk

For further details, we refer the user to the documentation of the pdftextsplitter-package, or to the mode details documentation in the docs-folder of this package.
djangotextsplitter is not very complicated. It just provides the database models and load/newwrite/overwrite/delete functions to the pdftextsplitter package, so the pdftextsplitter package can be efficiently used from within a django webapplication.
